USBLC6-4SC6 Alternative / Equivalent / Replacement - YINT ESDSRV05-4 Cross Reference

YINT Electronics | Product Knowledge Draft | USB and multi-line connector ESD protection

USBLC6-4SC6 alternative searches normally come from products that expose several low-voltage signal lines at a connector. YINT official Cross-reference Search records ESDSRV05-4 against the STMicroelectronics part, giving engineers and buyers a documented candidate for USB, service-port and compact connector designs.

1. Replacement Overview

For a USBLC6-4SC6 replacement review, begin with the protected line count and the connector circuit rather than the model name alone. A four-line array can reduce component count around USB 2.0, charging and service connectors, but the PCB footprint and internal steering topology must agree with the original design. The candidate should also be reviewed for reverse stand-off voltage, leakage, junction capacitance and clamping behavior. These checks are especially important where the protection device sits directly on a data pair and excessive capacitance could reduce eye-diagram margin. Placement close to the connector, a short discharge path to ground and a continuous return plane remain part of the protection system; changing the diode without reviewing the layout can produce misleading test results.

2. YINT Candidate Profile

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 USBLC6-4SC6 and YINT ESDSRV05-4

The official YINT mapping means that ESDSRV05-4 is a candidate for USBLC6-4SC6; 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.

• USB 2.0 data and charging ports on notebooks, hubs and docking stations.
• Industrial HMI and diagnostic service connectors exposed to repeated handling.
• Consumer electronics such as media players, accessories and test equipment.
• Compact embedded boards that need one array to protect several adjacent traces.

5. Replacement Qualification Checklist

Use a controlled checklist so the sourcing decision remains traceable and repeatable:

1. Confirm the complete ordering code, protection function, line count and directionality.
2. Compare package drawings, land pattern, pinout, height and tape orientation.
3. Review voltage, current, leakage, capacitance and clamping under equivalent tests.
4. Approve AEC-Q101, industrial grade or other project qualifications separately.
5. 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 USBLC6-4SC6 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.

8. Conclusion and Contact

YINT ESDSRV05-4 is the official cross-reference candidate identified for STMicroelectronics USBLC6-4SC6. 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.
