TQ2SS-L2-3V-X Equivalent & Substitute Parts

Part Overview

The TQ2SS-L2-3V-X is a telecom relay manufactured by Panasonic Electric Works, classified as a surface mount DPDT (2 Form C) component with 2A contact rating and 3VDC coil voltage. This relay is designed for telecommunications applications requiring dual-coil latching operation with fast switching characteristics. The part is currently active in production with RoHS compliance certification. Substitute parts are identified when packaging or inventory availability differs while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TQ2SS-L2-3V-X is determined by strict equivalence across the following critical parameters:

• Coil Voltage: 3VDC
• Contact Form: DPDT (2 Form C)
• Contact Rating: 2 A
• Switching Voltage: 125VAC, 220VDC - Max
• Coil Current: 46.7 mA
• Coil Type: Latching, Dual Coil
• Termination Style: Gull Wing
• Operating Temperature Range: -40°C ~ 85°C
• Contact Material: Silver Nickel (AgNi), Gold (Au)
• Coil Resistance: 64.3 Ohms
• Mounting Type: Surface Mount
• Series: TQ-SMD

Packaging format (Tape & Reel versus Tube) does not affect electrical or mechanical compatibility and therefore does not preclude substitution. The identified substitute maintains all specified parameters while differing only in packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

Both the TQ2SS-L2-3V-X and TQ2SS-L2-3V are active production components from Panasonic Electric Works with identical RoHS compliance certification. Selection between these parts should be based on packaging requirements and inventory availability. The Tape & Reel format (TQ2SS-L2-3V-X) is suitable for automated assembly processes, while the Tube format (TQ2SS-L2-3V) accommodates manual handling and smaller volume applications. Both configurations deliver equivalent electrical performance and mechanical reliability for telecommunications relay applications.

Frequently Asked Questions (FAQ)

Q: Can TQ2SS-L2-3V be used as a direct replacement for TQ2SS-L2-3V-X?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: TQ2SS-L2-3V-X uses Tape & Reel packaging while TQ2SS-L2-3V uses Tube packaging. This distinction affects handling and assembly processes but not component performance.

Q: What determines if a relay can substitute for the TQ2SS-L2-3V-X?

A: Substitution requires matching all critical parameters: 3VDC coil voltage, DPDT contact form, 2A contact rating, 125VAC/220VDC switching voltage, 46.7mA coil current, latching dual-coil configuration, gull wing termination, 4ms operate/release times, -40°C to 85°C operating range, and 64.3 Ohm coil resistance. Packaging format does not affect substitution eligibility.

Q: Are there inventory differences between the two part numbers?

A: Yes. TQ2SS-L2-3V-X (Tape & Reel) has 819 pieces in stock, while TQ2SS-L2-3V (Tube) has 2491 pieces in stock. Availability may influence part selection based on project timeline and volume requirements.

Q: Does packaging format affect PCB assembly compatibility?

A: Packaging format affects assembly methodology. Tape & Reel format supports automated pick-and-place assembly, while Tube format requires manual component handling. Both formats are compatible with standard surface mount PCB assembly when processed through appropriate equipment or procedures.

Q: Are both parts RoHS compliant?

A: Yes. Both TQ2SS-L2-3V-X and TQ2SS-L2-3V carry RoHS compliance certification and are suitable for applications requiring environmental regulatory adherence.
