• Mounting technology: Surface mount with gull wing termination
• Coil type: Latching, single coil operation
• Operating temperature range: -40°C to 85°C minimum
• Must operate voltage: 2.25 VDC or lower
• Switching performance: 4 ms operate and release times
• Packaging: Tape and reel format
• Compliance: RoHS compliant

The V23079J1108B301 manufactured by TE Connectivity Potter & Brumfield Relays meets all substitution criteria within the allowed parameter tolerance for this product category.

Parameter Comparison

Engineering Selection Recommendations

Both the TXD2SS-L-3V-Z and V23079J1108B301 are active production components with full RoHS compliance and identical ECCN and HTSUS classifications. Selection between these parts is based on application-specific requirements and supply availability.

The V23079J1108B301 operates at lower coil current (23.3 mA versus 50 mA) due to higher coil resistance (128 Ohms versus 60 Ohms), resulting in reduced power consumption during coil energization. This characteristic may be advantageous in power-constrained applications. The V23079J1108B301 additionally supports 250VAC switching voltage in addition to 220VDC maximum switching capability.

Both parts maintain identical electrical performance specifications for contact switching time, operating temperature range, and must-operate voltage threshold. Mechanical compatibility is confirmed through identical surface mount gull wing termination and tape and reel packaging format.

Frequently Asked Questions (FAQ)

Q: Can the V23079J1108B301 be used as a direct replacement for the TXD2SS-L-3V-Z?

A: Yes. Both relays meet all critical substitution parameters: 3VDC coil voltage, DPDT contact configuration, 2A contact rating, surface mount gull wing termination, latching single coil operation, and identical switching performance characteristics. Tape and reel packaging format is identical.

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

A: The TXD2SS-L-3V-Z draws 50 mA coil current, while the V23079J1108B301 draws 23.3 mA. This difference results from the higher coil resistance in the V23079J1108B301 (128 Ohms versus 60 Ohms). Both parts operate at the same 3VDC coil voltage and meet the 2.25 VDC must-operate threshold.

Q: Are there differences in switching voltage capability?

A: The TXD2SS-L-3V-Z is rated for 220VDC maximum switching voltage. The V23079J1108B301 supports both 250VAC and 220VDC maximum switching voltage, providing broader application flexibility.

Q: Do both parts have identical contact material composition?

A: Contact materials differ slightly. The TXD2SS-L-3V-Z uses Silver (Ag) and Gold (Au), while the V23079J1108B301 uses Silver Nickel (AgNi) and Gold (Au). Both compositions are suitable for general purpose relay applications within the specified 2A contact rating.

Q: Are both parts RoHS compliant?

A: Yes. Both the TXD2SS-L-3V-Z and V23079J1108B301 are RoHS compliant and share identical ECCN (EAR99) and HTSUS (8536.41.0020) classifications.

Q: What is the operating temperature range for both relays?

A: Both relays operate across the identical temperature range of -40°C to 85°C, with switching performance maintained at 4 ms operate and release times throughout this range.
