Key Parameters

Substitute Part Grouping Explanation

Substitution of the TXD2SS-5V-X is permissible when the alternative component maintains identical electrical and mechanical characteristics across the following critical parameters:

• Coil voltage specification (5VDC)
• Contact form configuration (DPDT / 2 Form C)
• Contact current rating (2 A minimum)
• Maximum switching voltage (220VDC or greater)
• Mounting type (Surface Mount)
• Termination style (Gull Wing)
• Coil current draw (40 mA)
• Operating temperature range (-40°C to 85°C minimum)
• Seal rating (Sealed - Fully)
• Coil type (Non Latching)

The TXD2SA-5V-Z meets all specified parameters and qualifies as a parametric equivalent within the TX-D series family.

Parameter Comparison

Engineering Selection Recommendations

Both the TXD2SS-5V-X and TXD2SA-5V-Z are active production components from Panasonic Electric Works within the TX-D relay series. The TXD2SA-5V-Z carries ROHS3 compliance certification, which represents an enhanced regulatory status compared to the standard RoHS compliance of the TXD2SS-5V-X. The TXD2SA-5V-Z additionally carries REACH Unaffected status.

Selection between these parts should be based on supply availability and regulatory requirements specific to the end application. Both components are electrically and mechanically interchangeable for applications requiring 5VDC DPDT surface mount relays with 2A contact rating and sealed construction.

Frequently Asked Questions (FAQ)

Q: Are TXD2SS-5V-X and TXD2SA-5V-Z electrically interchangeable?

A: Yes. Both relays share identical electrical specifications including coil voltage (5VDC), contact form (DPDT), current rating (2A), switching voltage (220VDC max), coil current (40 mA), and timing characteristics (4 ms operate and release times).

Q: Do these relays have the same physical footprint?

A: Yes. Both components use surface mount packaging with gull wing termination style, ensuring identical PCB layout compatibility.

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

A: ROHS3 represents the current regulatory standard with updated substance restrictions. The TXD2SA-5V-Z meets this enhanced standard, while the TXD2SS-5V-X meets the earlier RoHS standard. Both are compliant with their respective regulatory frameworks.

Q: Can I substitute TXD2SA-5V-Z for TXD2SS-5V-X in existing designs?

A: Yes, provided the design does not have specific constraints tied to the original part number. The electrical and mechanical parameters are identical, and the enhanced compliance status of the TXD2SA-5V-Z presents no compatibility issues.

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

A: Both relays operate across -40°C to 85°C, supporting applications in industrial and automotive environments.

Q: Are both parts available in tape and reel packaging?

A: Yes. Both TXD2SS-5V-X and TXD2SA-5V-Z are supplied in tape and reel (TR) packaging suitable for automated assembly processes.
