TXD2SL-L-5V-Z Equivalent & Substitute Parts

Part Overview

The TXD2SL-L-5V-Z is a general purpose relay manufactured by Panasonic Electric Works, configured as a DPDT (2 Form C) surface mount component with 2A contact rating and 5VDC coil voltage. This part is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and production continuity. Substitute parts must maintain functional equivalence across electrical and mechanical parameters while meeting current availability and compliance requirements.

Must Operate Voltage	3.75 VDC
Switching Voltage (Max)	220VDC

Substitute Part Grouping Explanation

Substitute parts for the TXD2SL-L-5V-Z are qualified based on the following mandatory parameters:

Contact form must be DPDT (2 Form C)
Contact rating must be 2 A minimum
Coil voltage must be 5VDC
Mounting type must be surface mount
Termination style must be gull wing
Coil type must be latching, single coil
Operating temperature range must encompass -40°C ~ 85°C
Must operate voltage must be 3.75 VDC or lower
Switching voltage capability must support 220VDC minimum

Both identified substitute parts meet these criteria and are classified as active products with current availability.

Engineering Selection Recommendations

Both substitute parts are classified as active products with current manufacturing status, providing long-term availability compared to the obsolete TXD2SL-L-5V-Z.

The 5-1462037-9 (TE Connectivity IM/AXICOM series) is RoHS3 compliant and offers hermetic sealing with faster switching times (3 ms operate/release versus 4 ms). This part is suitable for applications requiring enhanced environmental protection and reduced switching latency.

The V23079F1101B301 (TE Connectivity V23079/AXICOM series) is RoHS3 compliant and maintains identical switching times (4 ms) to the original part. This part provides the closest operational match to the TXD2SL-L-5V-Z.

Both substitute parts carry REACH unaffected status and EAR99 ECCN classification, matching the regulatory profile of the original component. Selection between substitutes should be based on specific application requirements regarding switching speed, sealing requirements, and coil current constraints.

Frequently Asked Questions (FAQ)

Q: Can the 5-1462037-9 be used as a direct replacement for the TXD2SL-L-5V-Z?

A: Yes. Both parts share identical contact form (DPDT), contact rating (2A), coil voltage (5VDC), mounting type (surface mount), termination style (gull wing), and operating temperature range (-40°C ~ 85°C). The 5-1462037-9 operates faster (3 ms versus 4 ms) and draws less coil current (20 mA versus 30 mA), making it functionally compatible for direct substitution.

Q: Can the V23079F1101B301 be used as a direct replacement for the TXD2SL-L-5V-Z?

A: Yes. Both parts share identical contact form (DPDT), contact rating (2A), coil voltage (5VDC), mounting type (surface mount), termination style (gull wing), operating temperature range (-40°C ~ 85°C), and switching times (4 ms). The V23079F1101B301 draws significantly less coil current (14 mA versus 30 mA), making it functionally compatible for direct substitution.

Q: What is the difference in coil current between the main part and substitutes?

A: The TXD2SL-L-5V-Z requires 30 mA coil current. The 5-1462037-9 requires 20 mA, and the V23079F1101B301 requires 14 mA. Lower coil current in substitute parts reduces power consumption and heat generation in the drive circuit.

Q: Are there packaging differences between these parts?

A: The TXD2SL-L-5V-Z packaging is not specified in available data. Both substitute parts are supplied in Tape & Reel (TR) packaging, which is standard for surface mount relay production and automated assembly processes.

Q: Do the substitute parts have different sealing specifications?

A: The TXD2SL-L-5V-Z is sealed fully. The 5-1462037-9 is sealed hermetically, providing enhanced environmental protection. The V23079F1101B301 sealing specification is not provided in available data.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the 5-1462037-9 and V23079F1101B301 are RoHS3 compliant, meeting current environmental and hazardous substance restrictions.
