Key Parameters

Substitute Part Grouping Explanation

Substitution of the TX2SL-L-24V is determined by strict equivalence across the following critical parameters:

• Contact configuration: DPDT (2 Form C)
• Contact current rating: 2 A minimum
• Coil voltage: 24VDC
• Coil type: Latching, single coil
• Mounting technology: Surface mount with gull wing termination
• Operating temperature range: -40°C to 85°C minimum
• Switching voltage capability: 220VDC or higher

The V23079F1105B301 from TE Connectivity Potter & Brumfield Relays meets all these criteria, classified as a general purpose relay with identical electrical and mechanical specifications to the TX2SL-L-24V.

Parameter Comparison

Engineering Selection Recommendations

The V23079F1105B301 serves as a direct functional equivalent for the TX2SL-L-24V. Both relays share identical contact configuration, current rating, coil voltage, and mounting specifications. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The V23079F1105B301 carries RoHS compliance certification and is available in Tape & Reel packaging, supporting automated assembly processes. The release time differential of 2 milliseconds (6 ms versus 4 ms) and coil resistance variation remain within acceptable tolerances for telecom relay applications and do not compromise functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the V23079F1105B301 directly replace the TX2SL-L-24V in existing designs?

A: Yes. Both relays meet identical electrical specifications for contact form, current rating, coil voltage, and coil type. Surface mount gull wing termination is identical, enabling direct PCB substitution without layout modification.

Q: What is the significance of the release time difference between these relays?

A: The TX2SL-L-24V releases in 4 ms while the V23079F1105B301 releases in 6 ms. This 2 ms difference is typical among relay variants and does not affect standard telecom switching applications. Circuit timing requirements should be evaluated for critical applications.

Q: Are there packaging differences between these parts?

A: The TX2SL-L-24V is supplied as new original stock without specified packaging. The V23079F1105B301 is available in Tape & Reel (TR) format, standard for automated surface mount assembly. Both use identical gull wing termination.

Q: What compliance certifications apply to the substitute part?

A: The V23079F1105B301 is RoHS compliant with Moisture Sensitivity Level 3 (168 hours). Both parts carry EAR99 ECCN classification and share identical HTSUS code 8536.41.0020.

Q: Why is the TX2SL-L-24V classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Panasonic Electric Works. The V23079F1105B301, maintained in active production by TE Connectivity, provides continuity for applications requiring DPDT 24VDC latching relay functionality.
