Key Parameters

Substitute Part Grouping Explanation

Substitution of the TXD2SL-L-24V-Z is determined by the following critical parameters:

• Coil Voltage: 24VDC (exact match required)
• Contact Form: DPDT (2 Form C) configuration
• Contact Rating: 2A minimum
• Mounting Type: Surface Mount with Gull Wing termination
• Coil Type: Latching, Single Coil operation
• Operating Temperature Range: -40°C ~ 85°C compatibility

The V23079F1105B301 from TE Connectivity Potter & Brumfield Relays satisfies all substitution criteria within these parameters.

Parameter Comparison

Engineering Selection Recommendations

The V23079F1105B301 is the designated substitute for the obsolete TXD2SL-L-24V-Z. Selection is based on the following factors:

• Product Status: The substitute is active and currently manufactured, ensuring long-term availability and supply chain continuity.
• Compliance: The V23079F1105B301 is RoHS Compliant, meeting current regulatory requirements. The main part carries REACH Unaffected status.
• Functional Equivalence: Both relays match across all critical electrical and mechanical parameters: 24VDC coil voltage, DPDT contact configuration, 2A contact rating, surface mount Gull Wing termination, and identical operating temperature range.
• Packaging Availability: The substitute is available in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the V23079F1105B301 directly replace the TXD2SL-L-24V-Z in existing designs?

A: Yes. Both relays share identical coil voltage (24VDC), contact form (DPDT), contact rating (2A), mounting type (surface mount), and termination style (Gull Wing). Operating temperature ranges are identical (-40°C ~ 85°C). The substitute is functionally equivalent for applications requiring these specifications.

Q: What is the difference in release time between the two relays?

A: The TXD2SL-L-24V-Z has a release time of 4 ms, while the V23079F1105B301 has a release time of 6 ms. This 2 ms difference must be evaluated against application timing requirements.

Q: Are there differences in coil resistance?

A: Yes. The TXD2SL-L-24V-Z has a coil resistance of 3.39 kOhms, while the V23079F1105B301 has a coil resistance of 8228 Ohms (approximately 8.23 kOhms). This difference affects coil current draw and must be considered in circuit design.

Q: What packaging options are available for the substitute?

A: The V23079F1105B301 is supplied in Tape & Reel (TR) packaging, standard for surface mount component automation.

Q: Is the substitute RoHS compliant?

A: Yes. The V23079F1105B301 is RoHS Compliant. The original TXD2SL-L-24V-Z carries REACH Unaffected status.

Q: What is the switching voltage capability of the substitute?

A: The V23079F1105B301 supports 250VAC and 220VDC maximum switching voltage, exceeding the original part's 220VDC maximum specification.
