Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TXS2SL-L-3V is determined by the following critical parameters:

• Coil voltage must be 3VDC
• Contact configuration must be DPDT (2 Form C)
• Mounting type must be surface mount with gull wing termination
• Coil type must be latching, single coil operation

The V23079F1108B301 qualifies as a substitute based on these core parameters. While the substitute part features a higher contact rating (2A versus 1A) and extended operating temperature range (-40°C ~ 85°C), these represent improvements over the original specification and do not prevent substitution. The substitute maintains identical coil voltage, contact form, mounting configuration, and coil type.

Parameter Comparison

Engineering Selection Recommendations

The V23079F1108B301 is the qualified substitute for the TXS2SL-L-3V based on matching core electrical and mechanical specifications. The substitute part carries active product status, ensuring ongoing availability and supply chain continuity compared to the obsolete original part.

The V23079F1108B301 is RoHS compliant, providing regulatory advantage for new designs and applications subject to environmental compliance requirements. The original TXS2SL-L-3V does not specify RoHS status.

Circuit design considerations include the higher coil current requirement (23.3 mA versus 11.7 mA) and lower coil resistance (128 Ohms versus 257 Ohms) of the substitute part. These differences necessitate verification of driver circuit capability to supply the increased coil current. The substitute part's faster switching times (4 ms versus 5 ms) and extended operating temperature range (-40°C ~ 85°C versus -40°C ~ 70°C) represent functional improvements suitable for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can the V23079F1108B301 directly replace the TXS2SL-L-3V in existing designs?

A: Direct replacement is possible when the circuit design accommodates the higher coil current requirement (23.3 mA). The substitute part maintains identical coil voltage (3VDC), contact configuration (DPDT), and mounting format (surface mount, gull wing termination). Circuit validation is required to confirm driver capability.

Q: What are the key differences between these parts?

A: The substitute part features higher contact current rating (2A versus 1A), extended operating temperature range (-40°C ~ 85°C versus -40°C ~ 70°C), faster switching times (4 ms versus 5 ms), and higher coil current demand (23.3 mA versus 11.7 mA). These represent performance enhancements rather than incompatibilities.

Q: Why is the coil current higher in the substitute part?

A: The V23079F1108B301 has lower coil resistance (128 Ohms versus 257 Ohms), resulting in higher current draw at the same 3VDC coil voltage. This is a direct consequence of the relay's internal design and does not affect functional compatibility when the driver circuit is rated for the higher current.

Q: Are there packaging considerations for substitution?

A: The TXS2SL-L-3V packaging is not specified in available documentation. The V23079F1108B301 is supplied in Tape & Reel (TR) format, standard for surface mount production environments. Footprint compatibility should be confirmed through mechanical drawings.

Q: What is the compliance status of the substitute part?

A: The V23079F1108B301 is RoHS compliant with Moisture Sensitivity Level (MSL) 3 (168 Hours), meeting environmental and handling requirements for modern manufacturing processes. The original part's compliance status is not specified.
