Key Parameters

Substitute Part Grouping Explanation

The substitute part 5-1462037-1 (TE Connectivity Potter & Brumfield Relays) qualifies as an equivalent based on the following critical parameters:

• Coil voltage matches at 1.5VDC
• Contact form is identical: DPDT (2 Form C)
• Contact current rating is equivalent at 2 A
• Mounting type is identical: Surface Mount
• Termination style matches: Gull Wing
• Coil type matches: Latching, Single Coil
• Operating temperature range is identical: -40°C ~ 85°C
• Relay type classification matches: Telecom
• Both parts maintain RoHS compliance (RoHS3 for substitute)

Substitution is valid when these core electrical and mechanical parameters align, enabling direct functional replacement in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

Both the TQ2SA-L-1.5V-Z and 5-1462037-1 are active production components with current RoHS compliance certifications. The TQ2SA-L-1.5V-Z maintains RoHS compliance, while the 5-1462037-1 meets ROHS3 compliance standards. The substitute part offers hermetic sealing, which provides enhanced environmental protection compared to the main part specification. Selection between these parts should be based on availability, packaging format (Tape & Reel versus Cut Tape), and specific application environmental requirements. Both parts are classified under ECCN EAR99 and HTSUS 8536.41.0020.

Frequently Asked Questions (FAQ)

Q: Can the 5-1462037-1 directly replace the TQ2SA-L-1.5V-Z in existing designs?

A: Yes. Both parts share identical coil voltage (1.5VDC), contact form (DPDT), current rating (2A), mounting type (Surface Mount), termination style (Gull Wing), and operating temperature range (-40°C ~ 85°C). The substitute part operates faster (3 ms versus 4 ms) and has higher switching voltage capability (250VAC versus 125VAC), making it functionally compatible.

Q: What are the differences in coil current between these parts?

A: The TQ2SA-L-1.5V-Z draws 46.9 mA, while the 5-1462037-1 draws 66.7 mA. This difference reflects different coil resistance values (32 Ohms versus 23 Ohms). Circuit designs must accommodate the higher current draw of the substitute part.

Q: Does packaging format affect substitution eligibility?

A: Packaging format (Tape & Reel for TQ2SA-L-1.5V-Z versus Cut Tape for 5-1462037-1) affects procurement and assembly processes but does not affect electrical or mechanical compatibility. Selection depends on manufacturing equipment and volume requirements.

Q: What is the significance of hermetic sealing on the substitute part?

A: The 5-1462037-1 includes hermetic sealing, providing enhanced protection against moisture and environmental contamination. The TQ2SA-L-1.5V-Z seal rating is not specified. Hermetic sealing is beneficial for applications requiring extended reliability in harsh or humid environments.

Q: Are both parts compliant with current regulatory standards?

A: Yes. The TQ2SA-L-1.5V-Z is RoHS Compliant. The 5-1462037-1 is ROHS3 Compliant and REACH Unaffected. Both parts carry EAR99 ECCN classification and HTSUS 8536.41.0020 tariff code.
