Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TXD2SL-L-12V-Z is determined by the following critical parameters:

• Contact form configuration: DPDT (2 Form C)
• Coil voltage: 12VDC
• Contact current rating: 2 A minimum
• Mounting type: Surface Mount
• Termination style: Gull Wing
• Operating temperature range: -40°C ~ 85°C minimum
• Coil type: Latching, Single Coil

The substitute part V23079F1103B301 (TE Connectivity Potter & Brumfield Relays) satisfies all critical substitution parameters. Both components share identical contact form configuration, coil voltage, contact rating, mounting type, termination style, operating temperature range, and coil type. Differences in coil current (12.5 mA vs. 5.8 mA), coil resistance (960 Ohms vs. 2.06 kOhms), and switching voltage capability (220VDC vs. 250VAC/220VDC) do not preclude functional equivalence within the specified application envelope.

Parameter Comparison

Engineering Selection Recommendations

The V23079F1103B301 is the primary equivalent substitute for the obsolete TXD2SL-L-12V-Z. Selection of this substitute is supported by the following factors:

• Active product status ensures ongoing availability and supply chain continuity
• RoHS compliance status provides regulatory alignment for new designs
• Identical electrical and mechanical parameters across all critical substitution criteria
• Gull Wing termination and surface mount configuration enable direct PCB layout compatibility
• Latching single coil operation maintains functional equivalence in circuit applications

The lower coil current requirement (5.8 mA vs. 12.5 mA) of the substitute part represents an operational advantage, reducing drive circuit power consumption without compromising switching performance.

Frequently Asked Questions (FAQ)

Q: Can the V23079F1103B301 be used as a direct replacement for the TXD2SL-L-12V-Z?

A: Yes. Both relays share identical contact form (DPDT), coil voltage (12VDC), contact rating (2A), mounting type (Surface Mount), termination style (Gull Wing), and operating temperature range (-40°C ~ 85°C). PCB footprint compatibility and electrical performance are equivalent.

Q: What is the difference in coil current between these two relays?

A: The TXD2SL-L-12V-Z requires 12.5 mA coil current, while the V23079F1103B301 requires 5.8 mA. This difference reflects different coil resistance values (960 Ohms vs. 2.06 kOhms) but does not affect functional substitution. The lower current requirement of the substitute part reduces drive circuit power dissipation.

Q: Are there packaging differences between these relays?

A: The TXD2SL-L-12V-Z packaging is not specified in available documentation. The V23079F1103B301 is supplied in Tape & Reel (TR) packaging, which is standard for surface mount relay applications and compatible with automated assembly processes.

Q: Does the substitute part meet RoHS compliance requirements?

A: Yes. The V23079F1103B301 is RoHS compliant. The TXD2SL-L-12V-Z RoHS status is not specified. For new designs requiring RoHS compliance, the V23079F1103B301 is the appropriate selection.

Q: What is the switching voltage capability difference?

A: The TXD2SL-L-12V-Z is rated for 220VDC maximum switching voltage. The V23079F1103B301 is rated for 250VAC or 220VDC maximum switching voltage. Both specifications accommodate the same DC switching envelope, with the substitute part offering additional AC switching capability.
