Substitute Part Grouping Explanation

Substitution of the TX2SL-L2-5V-Z is determined by strict equivalence across the following critical parameters:

• Coil Voltage: 5VDC (exact match required)
• Contact Form: DPDT (2 Form C) configuration
• Contact Rating: 2A minimum
• Coil Type: Latching, Dual Coil operation
• Mounting Type: Surface Mount with Gull Wing termination
• Operating Temperature Range: -40°C ~ 85°C minimum coverage
• Switching Voltage: 220VDC or higher maximum rating
• Timing Characteristics: 4 ms operate and release times

The V23079E1201B301 from TE Connectivity Potter & Brumfield Relays meets all substitution criteria, providing functional equivalence with enhanced availability and active product status.

Engineering Selection Recommendations

The V23079E1201B301 serves as the direct functional equivalent for TX2SL-L2-5V-Z replacement applications. Selection is supported by:

• Product Status: The substitute maintains active manufacturing status, ensuring long-term availability and supply chain continuity compared to the obsolete original part.
• Regulatory Compliance: The V23079E1201B301 carries ROHS3 compliance certification, meeting current environmental and material restriction requirements.
• Electrical Equivalence: All critical electrical parameters—coil voltage, contact configuration, current rating, switching voltage, and timing characteristics—are identical or superior.
• Mechanical Compatibility: Surface mount construction with Gull Wing termination ensures direct PCB footprint compatibility.
• Operational Characteristics: Coil current reduction (28 mA vs. 40 mA) in the substitute provides improved power efficiency without compromising switching performance.

Frequently Asked Questions (FAQ)

Q: Can the V23079E1201B301 be used as a direct replacement for TX2SL-L2-5V-Z in existing designs?

A: Yes. Both relays share identical coil voltage (5VDC), contact configuration (DPDT), current rating (2A), timing characteristics (4 ms), and operating temperature range (-40°C ~ 85°C). Surface mount Gull Wing termination ensures PCB footprint compatibility.

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

A: The V23079E1201B301 operates at 28 mA compared to 40 mA for the TX2SL-L2-5V-Z. This 30% reduction in coil current provides power efficiency benefits while maintaining identical switching performance and timing.

Q: Are there packaging differences between these parts?

A: The TX2SL-L2-5V-Z uses standard packaging, while the V23079E1201B301 is available in Cut Tape (CT) and Digi-Reel® formats. Both maintain identical component dimensions and PCB mounting characteristics.

Q: What is the significance of the coil resistance difference?

A: The V23079E1201B301 has 178 Ohms coil resistance versus 125 Ohms for the TX2SL-L2-5V-Z. This difference is consistent with the lower coil current specification and does not affect functional compatibility when driven by standard 5VDC control circuits.

Q: Does the contact material difference affect performance?

A: Both relays use gold-plated contacts for reliability. The TX2SL-L2-5V-Z uses pure silver with gold plating, while the V23079E1201B301 uses silver-nickel with gold plating. Both contact materials meet the 2A switching requirement and 220VDC maximum switching voltage specification.

Q: Is the V23079E1201B301 suitable for new designs?

A: Yes. The active product status, ROHS3 compliance, and superior availability make the V23079E1201B301 the appropriate choice for new telecommunications relay applications requiring DPDT 2A 5VDC latching operation.
