Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TX2SA-L-5V is determined by strict equivalence across the following critical parameters:

• Coil voltage: 5VDC
• Contact configuration: DPDT (2 Form C)
• Contact current rating: 2 A minimum
• Mounting type: Surface Mount
• Termination style: Gull Wing
• Coil type: Latching, Single Coil
• Operating temperature range: -40°C ~ 85°C minimum
• Must operate voltage: 3.75 VDC or lower
• Switching voltage capability: 220VDC or higher
• Operate and release time: 4 ms or faster

The V23079F1101B301 meets all substitution criteria within these parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the TX2SA-L-5V and V23079F1101B301 are active production components with current RoHS compliance certifications. The V23079F1101B301 demonstrates equivalent electrical performance across all critical switching and coil parameters. The lower coil current (14 mA versus 20 mA) in the TE Connectivity part results in reduced power consumption during operation. Both parts maintain identical operate and release timing at 4 ms and support the full -40°C to 85°C operating temperature range. Selection between these parts should be based on packaging requirements (Tube versus Tape & Reel), inventory availability, and application-specific compliance documentation needs.

Frequently Asked Questions (FAQ)

Q: Can the V23079F1101B301 directly replace the TX2SA-L-5V in existing designs?

A: Yes, provided that the application accommodates the packaging format change from Tube to Tape & Reel and accepts the coil resistance difference of 357 Ohms versus 250 Ohms. All electrical switching parameters, contact ratings, and timing specifications are equivalent.

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

A: The V23079F1101B301 operates at 14 mA coil current compared to 20 mA for the TX2SA-L-5V. This 6 mA reduction decreases power dissipation in the coil during energization, which may benefit thermal management in space-constrained applications. Both parts meet the 3.75 VDC must-operate voltage requirement.

Q: Are there differences in contact material composition?

A: The TX2SA-L-5V uses Silver (Ag) and Gold (Au) contact materials, while the V23079F1101B301 uses Silver Nickel (AgNi) and Gold (Au). Both compositions support the 2A contact rating and 220VDC switching voltage specification. Contact material selection should be evaluated based on specific load characteristics and environmental exposure in the application.

Q: What packaging considerations apply to substitution?

A: The TX2SA-L-5V is supplied in Tube packaging, while the V23079F1101B301 is supplied in Tape & Reel (TR) format. This affects handling, storage, and automated assembly processes. Tape & Reel packaging is standard for high-volume surface mount production environments.

Q: Do both parts meet the same compliance standards?

A: The TX2SA-L-5V is RoHS Compliant, and the V23079F1101B301 is ROHS3 Compliant. Both meet current environmental and hazardous substance restrictions. The V23079F1101B301 additionally carries REACH Unaffected status.
