NUP4201MR6T1G Alternative / Equivalent / Replacement - YINT ESDSRV05-4 Cross Reference
YINT Electronics | Product Knowledge Draft | Four-line ESD array sourcing and qualification
NUP4201MR6T1G replacement searches often start when a multi-line ESD array becomes difficult to source or a second supplier is required. YINT lists ESDSRV05-4 as the official cross-reference candidate, allowing procurement and engineering teams to organize a controlled comparison instead of relying on a name-only substitution.
1. Replacement Overview
| Original part number | Original manufacturer | YINT alternative | Review status |
|---|---|---|---|
| NUP4201MR6T1G | onsemi | ESDSRV05-4 | Candidate for qualification |
The main task in a NUP4201MR6T1G alternative review is to preserve the four protected channels while checking how the array is connected internally. Portable instruments, control panels and peripheral products may use similar looking six-lead packages with different common pins or signal routing. Confirming the schematic symbol, pin assignment and land pattern prevents a mechanically compatible package from being electrically incompatible. The next review layer covers working voltage, leakage, capacitance and dynamic clamping. These parameters influence both normal communication and the voltage that reaches downstream ICs during an ESD strike. If NUP4201MR6T1G is already qualified in a released product, the YINT candidate should be introduced through the project change-control process with traceable samples, assembly checks and board-level verification.
2. YINT Candidate Profile
| YINT model | ESDSRV05-4 |
|---|---|
| Device class | Four-line ESD protection array |
| Package class | SOT-23-6 class; verify footprint and pinout |
| Cross-reference status | Listed in YINT official database |
YINT ESDSRV05-4 is a four-line ESD protection-array candidate documented in the company cross-reference database. The currently available public page does not provide enough detail to approve an automatic replacement, so this draft does not invent unsupported numeric values. Obtain the latest controlled data sheets for both parts and compare working voltage, leakage, capacitance, clamping, current paths, package dimensions and pin assignment before release.
3. How to Compare NUP4201MR6T1G and YINT ESDSRV05-4
The official YINT mapping means that ESDSRV05-4 is a candidate for NUP4201MR6T1G; it does not mean that either device can be exchanged without verification. First compare function, directionality, protected-line count, common pins and every pin assignment. Next check the package drawing, land pattern, component height and tape orientation. Then compare working voltage, breakdown or clamping behavior, leakage, capacitance, peak current, pulse waveform and temperature range under equivalent test conditions.
For high-speed links, add eye-diagram, return-loss or error-rate testing as appropriate. For automotive, industrial or long-cable ports, repeat the project ESD, surge and system-immunity tests. The approval should identify the exact PCB revision, firmware state, cable, enclosure and test level, preventing a result from one connector or product variant from being reused without evidence.
4. Application Scenarios
The following equipment categories are practical starting points for evaluating the cross-reference. The final decision must follow the electrical limits, interface speed and immunity level of the actual product.
- Computer and peripheral I/O connectors that combine several exposed signal lines.
- Control-panel communication ports in factory and building automation equipment.
- Portable measurement instruments that are frequently connected in the field.
- General multi-line connectors where board area and component count are limited.
5. Replacement Qualification Checklist
Use a controlled checklist so the sourcing decision remains traceable and repeatable:
- Confirm the complete ordering code, protection function, line count and directionality.
- Compare package drawings, land pattern, pinout, height and tape orientation.
- Review voltage, current, leakage, capacitance and clamping under equivalent tests.
- Approve AEC-Q101, industrial grade or other project qualifications separately.
- Run ESD, surge and required signal-integrity tests on the target PCB.
6. Why Evaluate YINT Electronics
The reason to evaluate YINT ESDSRV05-4 for a NUP4201MR6T1G replacement is that the relationship is recorded in YINT's public cross-reference database, giving purchasing and engineering teams one traceable model from which to work. YINT can help confirm current inventory, reel packing, samples, quotation and application conditions, and can support a parameter comparison when project information is provided.
- Public mapping: the relationship can be checked on the YINT website rather than relying on an informal list.
- Product coverage: YINT supplies ESD, TVS, surge-protection and EMI-filtering devices for coordinated interface sourcing.
- Sample and supply support: contact YINT to verify available quantity, lead time and sample arrangements.
- Controlled engineering review: final selection remains based on controlled data sheets and tests on the target board.
7. Frequently Asked Questions
Q1: What is the YINT alternative to
YINT official Cross-reference Search maps the onsemi NUP4201MR6T1G to ESDSRV05-4, so ESDSRV05-4 is the candidate recommended for engineering review in this article.
Q2: Can ESDSRV05-4 replace NUP4201MR6T1G without qualification?
No. The cross-reference narrows the candidate search; production substitution still depends on current data sheets, package drawings, qualification requirements and application testing.
Q3: Which parameters matter most in the comparison?
Review working voltage, line count, directionality, leakage, capacitance, clamping, package and pinout, and confirm that values from both suppliers were measured under comparable conditions.
Q4: Is board-level or system-level testing required?
Yes. Complete the applicable ESD, surge and signal-integrity tests on the target PCB and assembled product.
Q5: How can buyers confirm stock, samples and pricing?
Contact Shanghai Yint Electronic Co., Ltd. with the target part number, quantity, application and required delivery date so current stock, samples and quotation can be checked.
8. Conclusion and Contact
YINT ESDSRV05-4 is the official cross-reference candidate identified for onsemi NUP4201MR6T1G. It provides a practical starting point for supply continuity, second-source qualification or a new design review, while the final release must remain tied to verified data sheets and target-system testing. Before purchasing release, record the approved application, test evidence and complete ordering code in the bill-of-materials change record.
