Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TX2SL-L2-12V is determined by strict alignment with the following critical parameters:

• Coil voltage: 12VDC
• Contact configuration: DPDT (2 Form C)
• Contact current rating: 2 A minimum
• Switching voltage capability: 220VDC or higher
• Coil type: Latching, dual coil
• Mounting type: Surface mount
• Termination style: Gull wing
• Operating temperature range: -40°C to 85°C minimum
• Switching speed: 4 ms operate and release time

The V23079E1203B301 qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. While classified as general purpose rather than telecom-specific, it maintains identical coil voltage, contact configuration, current rating, switching voltage capability, coil type, mounting configuration, and thermal operating range.

Engineering Selection Recommendations

The V23079E1203B301 is the qualified substitute for TX2SL-L2-12V applications. Selection rationale is based on the following factors:

Electrical Compatibility: Both relays operate at identical coil voltage (12VDC), contact configuration (DPDT), current rating (2A), and switching voltage limits (220VDC minimum). Coil must-operate voltage is identical at 9VDC, ensuring consistent control circuit performance.

Mechanical Compatibility: Both components feature surface mount gull wing termination, enabling direct PCB replacement without redesign of landing patterns or assembly processes.

Thermal Performance: Identical operating temperature range (-40°C to 85°C) ensures equivalent performance across specified environmental conditions.

Product Status Advantage: The V23079E1203B301 is classified as active, providing long-term availability and supply chain stability compared to the obsolete TX2SL-L2-12V.

Compliance: The V23079E1203B301 carries RoHS3 compliance certification, meeting modern regulatory requirements for new designs and manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can the V23079E1203B301 directly replace the TX2SL-L2-12V without circuit modification?

A: Yes. Both relays share identical coil voltage (12VDC), contact configuration (DPDT), current rating (2A), switching voltage capability (220VDC), and gull wing surface mount termination. No circuit redesign is required.

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

A: The TX2SL-L2-12V is designated telecom-grade, while the V23079E1203B301 is general-purpose. Both meet the specified electrical and mechanical parameters for this application. The general-purpose classification does not indicate reduced performance for the stated parameters.

Q: Are there differences in coil current consumption between these relays?

A: The TX2SL-L2-12V specifies 16.7 mA coil current, while the V23079E1203B301 specifies 11.7 mA. Both operate at 12VDC with identical must-operate voltage (9VDC). The lower coil current of the substitute may reduce power consumption in control circuits.

Q: What packaging formats are available for the V23079E1203B301?

A: The V23079E1203B301 is supplied in cut tape (CT) packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: Does the V23079E1203B301 meet RoHS requirements?

A: Yes. The V23079E1203B301 is RoHS3 compliant. The TX2SL-L2-12V REACH status is unaffected, and the substitute maintains equivalent regulatory standing for new applications.

Q: Are the contact materials equivalent between these relays?

A: The TX2SL-L2-12V uses silver (Ag) and gold (Au) contact materials. The V23079E1203B301 uses silver nickel (AgNi) and gold (Au). Both material systems are suitable for 2A switching applications at the specified voltage levels.
