TQ2SS-L-3V-Z Equivalent & Substitute Parts

Part Overview

The TQ2SS-L-3V-Z is an active telecom relay manufactured by Panasonic Electric Works, configured as a DPDT (2 Form C) surface mount component with 2A contact rating and 3VDC coil voltage. This part is designed for telecommunications applications requiring latching, single-coil operation in compact surface mount packages. Equivalent and substitute parts are identified to provide procurement flexibility, inventory alternatives, and continuity of supply for applications where the primary part may be unavailable or where design requirements permit functional substitution.

Key Parameters

Substitute Part Grouping Explanation

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

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

The identified substitute parts meet all critical substitution criteria. Variations in coil current, coil resistance, operate/release time, switching voltage, contact material composition, and seal rating do not preclude functional substitution when the above parameters align.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and comply with applicable regulatory requirements (RoHS/ROHS3). Selection between the TQ2SS-L-3V-Z and its substitutes should be based on the following factors:

TQ2SS-L-3V-Z (Panasonic Electric Works): Primary choice when original specification and telecom-grade classification are required. RoHS Compliant status applies.

5-1462037-4 (TE Connectivity): Acceptable substitute with hermetically sealed construction and ROHS3 Compliant status. Higher coil current (33.3 mA vs. 23.3 mA) and lower coil resistance (90 Ohms vs. 129 Ohms) may require circuit verification. Faster operate/release time (3 ms vs. 4 ms) may benefit timing-sensitive applications. Available in higher inventory quantities.

V23079J1108B301 (TE Connectivity): Acceptable substitute with matching coil current and operate/release time specifications. General Purpose relay classification differs from telecom designation of primary part. RoHS Compliant status applies. Identical electrical performance characteristics to primary part.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical coil voltage (3VDC), contact form (DPDT), contact rating (2A), mounting type (Surface Mount), coil type (Latching, Single Coil), termination style (Gull Wing), operating temperature range (-40°C ~ 85°C), and must operate voltage (2.25 VDC). The higher coil current and lower coil resistance of 5-1462037-4 require circuit-level verification to ensure compatibility with existing drive circuitry.

Q: What is the difference between the telecom relay (TQ2SS-L-3V-Z) and the general purpose relay (V23079J1108B301)?

A: The primary difference is application classification. Both parts are functionally equivalent with identical electrical specifications (coil voltage, contact form, contact rating, coil current, operate/release time, and operating temperature). Telecom relays are typically designed and tested for telecommunications infrastructure applications, while general purpose relays serve broader industrial applications. Selection depends on application requirements and qualification standards.

Q: Are there packaging differences between these parts?

A: Yes. TQ2SS-L-3V-Z and V23079J1108B301 are supplied in Tape & Reel (TR) packaging. 5-1462037-4 is supplied in Cut Tape (CT) and Digi-Reel® packaging. Packaging selection affects handling, storage, and automated assembly processes.

Q: Do all three parts meet RoHS compliance?

A: Yes. TQ2SS-L-3V-Z and V23079J1108B301 are RoHS Compliant. 5-1462037-4 is ROHS3 Compliant, which represents a more recent revision of the RoHS standard. Both compliance levels are acceptable for most applications.

Q: What is the significance of the 1 ms difference in operate/release time between TQ2SS-L-3V-Z and 5-1462037-4?

A: The 5-1462037-4 operates and releases 1 ms faster (3 ms vs. 4 ms). This difference is significant only in applications with strict timing requirements or high-frequency switching operations. For standard telecommunications applications, this difference is typically negligible.
