Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TXD2SA-3V-X are identified based on strict electrical and mechanical parameter equivalence within the TX-D series. The substitution criteria are:

• Identical coil voltage (3VDC)
• Identical contact form (DPDT / 2 Form C)
• Identical contact rating (2 A)
• Identical mounting type (Surface Mount)
• Identical termination style (Gull Wing)
• Identical coil resistance (45 Ohms)
• Identical operating temperature range (-40°C ~ 85°C)
• Identical switching voltage rating (220VDC Max)
• Same manufacturer (Panasonic Electric Works)
• Active product status

The TXD2SA-3V-Z meets all substitution criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both TXD2SA-3V-X and TXD2SA-3V-Z are Active status products from Panasonic Electric Works with identical electrical and mechanical specifications. The TXD2SA-3V-X carries RoHS Compliant certification, while the TXD2SA-3V-Z carries ROHS3 Compliant certification with additional REACH Unaffected status. Selection between these parts should be based on regulatory compliance requirements specific to the application and end-use region. Both parts are suitable for direct substitution in 3VDC DPDT relay applications requiring 2A contact rating and surface mount gull wing termination.

Frequently Asked Questions (FAQ)

Q: Can TXD2SA-3V-Z replace TXD2SA-3V-X in existing designs?

A: Yes. Both parts maintain identical electrical parameters including coil voltage, contact form, contact rating, coil resistance, timing characteristics, and operating temperature range. Surface mount gull wing termination is identical, enabling direct PCB footprint compatibility.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: RoHS Compliant indicates conformance to the original Restriction of Hazardous Substances directive. ROHS3 Compliant indicates conformance to the updated RoHS 3 directive (2015/863/EU), which includes additional restricted substances. Selection depends on regulatory requirements for the target market.

Q: Are the coil characteristics identical between these parts?

A: Yes. Both parts have 3VDC coil voltage, 45 Ohms coil resistance, 66.7 mA coil current, 2.25 VDC must operate voltage, 0.3 VDC must release voltage, and 4 ms operate and release times.

Q: What is the contact rating for these relays?

A: Both parts are rated for 2A continuous contact current with a maximum switching voltage of 220VDC. Contact material is Silver (Ag) and Gold (Au) with fully sealed construction.

Q: Are these parts available in different packaging options?

A: Both TXD2SA-3V-X and TXD2SA-3V-Z are supplied in Tape & Reel (TR) packaging for automated assembly processes.
