TQ2SL-L2-24V-Z Equivalent & Substitute Parts

Part Overview

The TQ2SL-L2-24V-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 24VDC coil voltage. This relay is designed for telecommunications applications requiring dual-coil latching operation. Substitute parts are identified to provide alternative sourcing options when the primary component becomes unavailable or when inventory constraints require alternative procurement channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TQ2SL-L2-24V-Z is determined by strict alignment of the following critical parameters:

• Coil voltage: 24VDC
• Contact form: DPDT (2 Form C)
• Contact rating: 2 A minimum
• Mounting type: Surface Mount
• Termination style: Gull Wing
• Operating temperature range: -40°C ~ 85°C minimum
• Coil type: Latching, Dual Coil
• Must operate voltage: 18 VDC

The V23079E1205B301 satisfies all substitution criteria. While classified as a general purpose relay rather than telecom-specific, it maintains electrical and mechanical compatibility across all specified parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the TQ2SL-L2-24V-Z and V23079E1205B301 maintain active product status with current manufacturing support. The TQ2SL-L2-24V-Z is RoHS Compliant, while the V23079E1205B301 is ROHS3 Compliant, indicating both meet environmental regulatory requirements. The V23079E1205B301 offers higher AC switching voltage capability (250VAC vs. 125VAC) and lower coil current consumption (5.8 mA vs. 8.3 mA), with a higher coil resistance value (4.11 kOhms vs. 2.88 kOhms). Selection between these parts should be based on specific application requirements regarding switching voltage levels and power consumption constraints.

Frequently Asked Questions (FAQ)

Q: Can the V23079E1205B301 directly replace the TQ2SL-L2-24V-Z in existing designs?

A: Yes, provided the application does not exceed 125VAC switching voltage. The V23079E1205B301 supports higher AC switching voltage (250VAC), making it suitable for applications within the TQ2SL-L2-24V-Z specification range. All critical electrical and mechanical parameters align.

Q: What is the difference between telecom and general purpose relay classifications?

A: The TQ2SL-L2-24V-Z is designated for telecommunications applications, while the V23079E1205B301 is classified as general purpose. Both share identical electrical specifications and contact configurations. Classification reflects intended market segment rather than functional capability differences.

Q: Are there packaging differences between these parts?

A: Yes. The TQ2SL-L2-24V-Z is supplied in Tape & Reel (TR) packaging, while the V23079E1205B301 is supplied in Cut Tape (CT) packaging. Both use Gull Wing termination style and are surface mount components compatible with standard pick-and-place assembly equipment.

Q: How do coil resistance differences affect circuit design?

A: The V23079E1205B301 has higher coil resistance (4.11 kOhms vs. 2.88 kOhms) and lower coil current (5.8 mA vs. 8.3 mA). Circuits designed for the TQ2SL-L2-24V-Z will function with the V23079E1205B301, though driver circuits may require adjustment if designed with tight current margins.

Q: Are both parts RoHS compliant?

A: Yes. The TQ2SL-L2-24V-Z is RoHS Compliant, and the V23079E1205B301 is ROHS3 Compliant. Both meet environmental compliance requirements for restricted substance use.
