TX2SL-9V Equivalent & Substitute Parts

Part Overview

The TX2SL-9V is a telecom relay manufactured by Panasonic Electric Works, configured as a DPDT (2 Form C) surface mount component with 2A contact rating and 9VDC coil voltage. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The TX2SL-9V operates across industrial temperature ranges and is fully sealed for telecom applications.

Substitute Part Grouping Explanation

Substitution for the TX2SL-9V is determined by strict electrical and mechanical parameter matching:

Parametric Equivalents (TX2SA-9V, TX2SS-9V): These parts share identical electrical specifications with the TX2SL-9V across all critical parameters: 9VDC coil voltage, DPDT contact form, 2A contact rating, 220VDC maximum switching voltage, 15.5 mA coil current, 579 Ohms coil resistance, and -40°C to 85°C operating temperature range. Both maintain surface mount gull wing termination and fully sealed construction. The primary distinction is product status: TX2SA-9V and TX2SS-9V are active production parts, whereas TX2SL-9V is obsolete. TX2SA-9V carries RoHS3 compliance, and TX2SS-9V carries RoHS compliance.

Similar Substitute (V23079D1006B301): This TE Connectivity Potter & Brumfield relay matches the TX2SL-9V on core electrical parameters: 9VDC coil voltage, DPDT contact form, 2A contact rating, 15.6 mA coil current, 578 Ohms coil resistance, and identical operating temperature range. The switching voltage specification extends to 250VAC and 220VDC maximum. Contact material differs slightly (Silver Nickel and Gold versus Silver and Gold). This part is classified as general purpose rather than telecom-specific and carries RoHS compliance with MSL 3 rating.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents): TX2SA-9V and TX2SS-9V are the primary substitutes for TX2SL-9V. Both are active production parts from the same manufacturer with identical electrical and mechanical specifications. TX2SA-9V is recommended for new designs requiring RoHS3 compliance. TX2SS-9V is suitable for applications requiring RoHS compliance. Both maintain the telecom relay classification and fully sealed construction of the original part.

For Alternative Applications (Similar Substitute): V23079D1006B301 from TE Connectivity Potter & Brumfield provides functional equivalence with extended switching voltage capability (250VAC addition). This part is classified as general purpose rather than telecom-specific and does not specify seal rating. The contact material composition differs slightly. This substitute is appropriate when telecom-specific classification is not a design requirement and when the extended AC switching voltage capability is beneficial.

Frequently Asked Questions (FAQ)

Q: Can TX2SA-9V or TX2SS-9V be used as direct replacements for TX2SL-9V?

A: Yes. Both parts are parametric equivalents with identical coil voltage (9VDC), contact form (DPDT), current rating (2A), switching voltage (220VDC max), coil current (15.5 mA), operating temperature range (-40°C to 85°C), and coil resistance (579 Ohms). Surface mount gull wing termination and fully sealed construction are maintained. The primary difference is product status: TX2SA-9V and TX2SS-9V are active production parts.

Q: What is the difference between TX2SA-9V and TX2SS-9V?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The distinction is regulatory compliance: TX2SA-9V carries RoHS3 compliance, while TX2SS-9V carries RoHS compliance. Selection depends on the specific regulatory requirements of the application.

Q: Can V23079D1006B301 replace TX2SL-9V?

A: V23079D1006B301 is a functional equivalent with matching coil voltage, contact form, current rating, and operating temperature range. However, it is classified as a general purpose relay rather than telecom-specific, and seal rating is not specified. The contact material composition differs (Silver Nickel and Gold versus Silver and Gold). This substitute is suitable when telecom classification is not required and when the extended AC switching voltage capability (250VAC) is acceptable.

Q: What packaging options are available for substitutes?

A: TX2SA-9V and TX2SS-9V are supplied in Tube packaging. V23079D1006B301 is supplied in Tape & Reel (TR) packaging. Packaging selection depends on assembly process requirements and inventory management practices.

Q: Are all substitutes RoHS compliant?

A: TX2SA-9V is RoHS3 compliant. TX2SS-9V is RoHS compliant. V23079D1006B301 is RoHS compliant. The original TX2SL-9V is classified as REACH Unaffected. Compliance status should be verified against specific design and regulatory requirements.
