Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TQ2SA-L-12V-Z is determined by strict equivalence across the following critical parameters:

• Coil voltage: 12VDC (exact match required)
• Contact configuration: DPDT (2 Form C) (exact match required)
• Contact current rating: 2 A (exact match required)
• Mounting technology: Surface mount with gull wing termination (exact match required)
• Coil type: Latching, single coil operation (exact match required)
• Operating temperature range: -40°C ~ 85°C (exact match required)
• Must operate voltage: 9 VDC (exact match required)
• Relay classification: Telecom (exact match required)

The substitute part 6-1462037-7 (TE Connectivity Potter & Brumfield Relays) meets all mandatory electrical and mechanical criteria for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Both the TQ2SA-L-12V-Z and 6-1462037-7 maintain active product status with current manufacturing support. The TQ2SA-L-12V-Z carries RoHS compliance certification, while the 6-1462037-7 meets ROHS3 compliance standards. Both components are classified as EAR99 for export control purposes and share identical HTSUS commodity codes (8536.41.0020).

The 6-1462037-7 provides enhanced switching voltage capability (250VAC maximum versus 125VAC) and faster switching response times (3 ms operate and release versus 4 ms), with hermetic sealing and MSL 3 moisture sensitivity rating. The TQ2SA-L-12V-Z operates at lower coil current (5.8 mA versus 8.3 mA) and higher coil resistance (2.06 kOhms versus 1.44 kOhms).

Selection between these parts depends on application-specific requirements for switching voltage, coil power consumption, and environmental sealing specifications, with both meeting the core functional and compliance criteria for telecom relay applications.

Frequently Asked Questions (FAQ)

Q: Can the 6-1462037-7 directly replace the TQ2SA-L-12V-Z in existing designs?

A: Yes. Both parts share identical coil voltage (12VDC), contact configuration (DPDT), current rating (2 A), mounting type (surface mount), termination style (gull wing), operating temperature range (-40°C ~ 85°C), and must-operate voltage (9 VDC). These parameters define functional equivalence for telecom relay applications.

Q: What are the differences in switching performance?

A: The 6-1462037-7 operates and releases 1 millisecond faster (3 ms versus 4 ms). The 6-1462037-7 also supports higher maximum switching voltage (250VAC versus 125VAC at the AC rating).

Q: Are there packaging differences?

A: Yes. The TQ2SA-L-12V-Z is supplied in tape & reel (TR) packaging, while the 6-1462037-7 is available in cut tape (CT) and Digi-Reel® formats. Packaging selection depends on assembly equipment and procurement volume requirements.

Q: Do both parts meet environmental compliance standards?

A: Both parts are active products with current RoHS compliance. The TQ2SA-L-12V-Z is RoHS compliant, and the 6-1462037-7 meets ROHS3 standards. Both are classified as EAR99 for export control.

Q: What is the difference in coil current consumption?

A: The TQ2SA-L-12V-Z draws 5.8 mA, while the 6-1462037-7 draws 8.3 mA. This difference reflects different coil resistance values (2.06 kOhms versus 1.44 kOhms) and may impact power supply design in current-limited applications.

Q: Is the 6-1462037-7 sealed?

A: Yes. The 6-1462037-7 is hermetically sealed with MSL 3 moisture sensitivity rating. The TQ2SA-L-12V-Z seal rating is not specified in the provided parameters.
