Parameter Comparison

Engineering Selection Recommendations

Both the TQ2SS-L-5V-Z and 5-1462037-9 are active production components with current inventory availability. The TQ2SS-L-5V-Z maintains RoHS compliance, while the 5-1462037-9 meets ROHS3 compliance standards. Both parts carry EAR99 ECCN classification and identical HTSUS codes (8536.41.0020), confirming regulatory alignment for telecom relay applications.

The 5-1462037-9 offers hermetically sealed construction with faster switching times (3 ms operate and release versus 4 ms), while the TQ2SS-L-5V-Z operates at lower coil current (14 mA versus 20 mA). Selection between these parts depends on specific application requirements regarding switching speed, power consumption, and environmental sealing specifications.

Frequently Asked Questions (FAQ)

Q: Can the 5-1462037-9 directly replace the TQ2SS-L-5V-Z in existing designs?

A: Yes, both parts share identical coil voltage (5VDC), contact form (DPDT), current rating (2A), mounting type (Surface Mount), termination style (Gull Wing), and operating temperature range (-40°C ~ 85°C). Direct substitution is electrically and mechanically compatible.

Q: What are the differences in switching performance?

A: The 5-1462037-9 operates and releases in 3 ms, compared to 4 ms for the TQ2SS-L-5V-Z. This 1 ms difference may be significant in time-critical applications but does not affect functional compatibility in standard telecom relay circuits.

Q: How do coil current requirements differ?

A: The TQ2SS-L-5V-Z requires 14 mA coil current, while the 5-1462037-9 requires 20 mA. Applications with strict power budget constraints may favor the lower current requirement of the TQ2SS-L-5V-Z.

Q: Are there environmental sealing differences?

A: The 5-1462037-9 features hermetically sealed construction, while the TQ2SS-L-5V-Z does not specify a seal rating. Hermetic sealing provides enhanced protection in harsh or moisture-prone environments.

Q: Do both parts meet the same regulatory standards?

A: Both parts are RoHS compliant (TQ2SS-L-5V-Z: RoHS Compliant; 5-1462037-9: ROHS3 Compliant) and carry identical ECCN and HTSUS classifications, confirming regulatory compatibility for telecom applications.

Q: What is the difference in coil resistance?

A: The TQ2SS-L-5V-Z has 357 Ohms coil resistance, while the 5-1462037-9 has 250 Ohms. This difference reflects different coil designs but does not affect substitution compatibility when both are driven by equivalent 5VDC control circuits.
