TQ2SS-L-3V Equivalent & Substitute Parts

Part Overview

The TQ2SS-L-3V is a telecom relay manufactured by Panasonic Electric Works, featuring DPDT (2 Form C) contact configuration with 2A contact rating and 3VDC coil voltage. This surface mount component is designed for telecommunications applications requiring latching, single coil operation. The part is currently active in production with RoHS compliance certification. Substitute parts are identified to provide alternative sourcing options when the primary component becomes unavailable or when inventory requirements necessitate alternative suppliers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TQ2SS-L-3V is determined by the following critical parameters:

• Coil voltage: 3VDC (exact match required)
• Contact form: DPDT (2 Form C) (exact match required)
• Contact rating: 2 A (exact match required)
• Mounting type: Surface Mount (exact match required)
• Termination style: Gull Wing (exact match required)
• Coil type: Latching, Single Coil (exact match required)
• Operating temperature range: -40°C ~ 85°C (exact match required)
• Must operate voltage: 2.25 VDC (exact match required)

The identified substitute parts meet all critical electrical and mechanical parameters. Variations in secondary parameters such as coil current, coil resistance, switching voltage maximum rating, contact material composition, and seal rating do not preclude substitution when the primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status with current RoHS compliance certifications. The TQ2SS-L-3V and V23079J1108B301 share identical operate and release times (4 ms), coil current (23.3 mA), and coil resistance values (128-129 Ohms), making V23079J1108B301 the closest functional equivalent. The 5-1462037-4 exhibits faster switching performance (3 ms operate and release times) and higher coil current (33.3 mA) due to lower coil resistance (90 Ohms), with the additional benefit of hermetic sealing. Selection between substitutes should be based on application-specific requirements for switching speed, power dissipation tolerance, and environmental sealing needs, all of which remain within acceptable parameters for DPDT 2A 3V relay applications.

Frequently Asked Questions (FAQ)

Q: Can the 5-1462037-4 be used as a direct replacement for the TQ2SS-L-3V?

A: Yes. The 5-1462037-4 meets all critical substitution parameters: 3VDC coil voltage, DPDT contact form, 2A contact rating, surface mount configuration, and gull wing termination. The faster switching times (3 ms vs. 4 ms) and higher coil current represent performance enhancements rather than incompatibilities.

Q: What is the difference between the V23079J1108B301 and the TQ2SS-L-3V?

A: The V23079J1108B301 is functionally equivalent to the TQ2SS-L-3V across all critical parameters. Both share identical switching times (4 ms), coil current (23.3 mA), and coil resistance values. The V23079J1108B301 is classified as a general purpose relay versus the telecom classification of the TQ2SS-L-3V, but this distinction does not affect electrical or mechanical compatibility.

Q: Are there packaging differences between these parts?

A: Yes. The TQ2SS-L-3V is supplied in Tube packaging. The 5-1462037-4 is available in Cut Tape (CT) & Digi-Reel® packaging. The V23079J1108B301 is supplied in Tape & Reel (TR) packaging. Packaging format does not affect component functionality or substitutability.

Q: Does the hermetic sealing on the 5-1462037-4 affect its use in non-sealed applications?

A: No. Hermetic sealing is an additional feature that provides enhanced environmental protection. A hermetically sealed component functions identically to a non-sealed equivalent in standard applications and offers no disadvantage when used as a substitute.

Q: Are all three parts RoHS compliant?

A: Yes. The TQ2SS-L-3V and V23079J1108B301 are RoHS Compliant. The 5-1462037-4 is ROHS3 Compliant, which represents an updated compliance standard. All three parts meet RoHS requirements.
