TQ2SL-9V-X Equivalent & Substitute Parts

Part Overview

The TQ2SL-9V-X is an active telecom relay manufactured by Panasonic Electric Works, designed for surface mount applications requiring DPDT switching functionality at 9VDC coil voltage. This part operates with a 2A contact rating and supports switching voltages up to 125VAC and 220VDC maximum. The component is RoHS compliant and suitable for telecommunications and industrial control applications. Substitute parts are identified to provide alternative sourcing options when the primary part number becomes unavailable or when inventory requirements necessitate alternative suppliers or packaging configurations.

Substitute Part Grouping Explanation

The TQ2SL-9V-X and TQ2SA-9V-Z are classified as parametric equivalents based on identical electrical and mechanical specifications. Substitution is valid when the following critical parameters match:

Coil voltage: 9VDC
Contact form: DPDT (2 Form C)
Contact rating: 2 A
Switching voltage: 125VAC, 220VDC maximum
Coil current: 15.5 mA
Mounting type: Surface Mount
Termination style: Gull Wing
Operating temperature range: -40°C ~ 85°C
Coil resistance: 579 Ohms
Must operate voltage: 6.75 VDC
Must release voltage: 0.9 VDC
Operate time: 4 ms
Release time: 4 ms

Both parts are manufactured by Panasonic Electric Works within the TQ-SMD series and maintain identical functional performance characteristics. The difference between TQ2SL-9V-X and TQ2SA-9V-Z lies in the base product designation (TQ2SL versus TQ2SA), which reflects internal Panasonic product line segmentation but does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can TQ2SA-9V-Z be used as a direct replacement for TQ2SL-9V-X?

A: Yes. Both parts are parametric equivalents with identical electrical characteristics, contact ratings, coil specifications, and switching performance. They are interchangeable at the circuit level.

Q: What is the difference between TQ2SL and TQ2SA base product designations?

A: The base product designation reflects Panasonic's internal product line organization. Both designations within the TQ-SMD series maintain identical functional specifications for the 9VDC DPDT configuration.

Q: Are there any compliance differences between these parts?

A: TQ2SA-9V-Z includes ROHS3 Compliant and REACH Unaffected certifications, while TQ2SL-9V-X carries RoHS Compliant status. Both meet environmental standards; TQ2SA-9V-Z provides additional compliance documentation.

Q: What are the critical parameters for substitution?

A: Coil voltage (9VDC), contact form (DPDT), contact rating (2A), switching voltage (125VAC/220VDC max), mounting type (Surface Mount), and termination style (Gull Wing) must remain constant for functional equivalence.

Q: Can these relays be used in applications requiring switching frequencies above 4 ms?

A: The specified operate and release times are 4 ms. Application requirements must align with these timing specifications.

Q: Are both parts suitable for the full operating temperature range?

A: Yes. Both TQ2SL-9V-X and TQ2SA-9V-Z are rated for -40°C to 85°C operation.
