• Contact rating: 2 A (identical)
• Mounting type: Surface mount (identical)
• Termination style: Gull wing (identical)
• Coil type: Latching, single coil (identical)
• Operating temperature range: -40°C ~ 85°C (identical)
• Must operate voltage: 6.75 VDC (identical)
• Relay type: Telecom (identical)
• Packaging: Tape & reel (identical)

Both parts meet the core functional and mechanical requirements for direct substitution in telecom relay applications.

Parameter Comparison

Engineering Selection Recommendations

Both the TQ2SS-L-9V-Z and 6-1462037-4 are active products with current manufacturing status. The TQ2SS-L-9V-Z is RoHS compliant, while the 6-1462037-4 meets ROHS3 compliance and includes hermetic sealing. The substitute part exhibits faster switching times (3 ms operate and release versus 4 ms) and higher maximum switching voltage (250VAC versus 125VAC). The coil current differential (11.1 mA versus 7.8 mA) and coil resistance variation (810 Ohms versus 1.16 kOhms) reflect design differences between manufacturers but do not prevent functional equivalence given identical coil voltage and must-operate specifications. Both parts are packaged identically in tape & reel format and maintain the same operating temperature range and contact rating.

Frequently Asked Questions (FAQ)

Q: Can 6-1462037-4 directly replace TQ2SS-L-9V-Z in existing designs?

A: Yes. Both parts share identical coil voltage (9VDC), contact form (DPDT), contact rating (2A), mounting type (surface mount), termination style (gull wing), and operating temperature range (-40°C ~ 85°C). The must-operate voltage specification (6.75 VDC) is identical, confirming functional compatibility.

Q: What are the differences in switching performance?

A: The 6-1462037-4 operates and releases 1 millisecond faster than the TQ2SS-L-9V-Z (3 ms versus 4 ms). This faster response time may be advantageous in time-sensitive applications but does not prevent substitution in designs tolerating the original 4 ms specification.

Q: How do the coil current specifications differ?

A: The TQ2SS-L-9V-Z draws 7.8 mA while the 6-1462037-4 draws 11.1 mA at 9VDC. This difference reflects internal design variations between manufacturers. Both parts meet the 6.75 VDC must-operate voltage requirement, indicating adequate coil design for the specified voltage range.

Q: Are there compliance differences?

A: The TQ2SS-L-9V-Z is RoHS compliant. The 6-1462037-4 meets ROHS3 compliance and includes hermetic sealing, providing enhanced environmental protection. Both parts carry EAR99 ECCN classification and identical HTSUS codes.

Q: What is the significance of contact material differences?

A: The TQ2SS-L-9V-Z uses Silver Nickel and Gold contact materials, while the 6-1462037-4 uses Palladium, Ruthenium, and Gold. Both material sets are standard for telecom relay applications and support the 2A contact rating and specified switching voltages.

Q: Are both parts available in the same packaging format?

A: Yes. Both the TQ2SS-L-9V-Z and 6-1462037-4 are supplied in tape & reel (TR) packaging, enabling direct substitution in automated assembly processes.
