Parameter Comparison

Engineering Selection Recommendations

Both the TX2SS-9V and TX2SA-9V are active production components from Panasonic Electric Works with identical electrical and mechanical specifications. The TX2SS-9V carries RoHS Compliance certification, while the TX2SA-9V carries ROHS3 Compliance and REACH Unaffected status. Selection between these parts should be based on regulatory requirements specific to the application and end-market destination. Both parts are suitable for telecommunications relay applications requiring DPDT switching at 9VDC with 2A contact capacity and sealed enclosure design.

Frequently Asked Questions (FAQ)

Q: Can TX2SA-9V replace TX2SS-9V in existing designs?

A: Yes. Both parts share identical electrical parameters (9VDC coil, DPDT contact form, 2A rating, 220VDC switching voltage, 579 Ohm coil resistance) and mechanical specifications (surface mount, gull wing termination, sealed enclosure). Direct substitution is supported without circuit modification.

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 resistance and operating voltage specifications identical?

A: Yes. Both parts specify 579 Ohm coil resistance, 9VDC coil voltage, 6.75 VDC must operate voltage, and 0.9 VDC must release voltage. Switching characteristics (4 ms operate time, 4 ms release time) are also identical.

Q: What is the packaging format for both parts?

A: Both TX2SS-9V and TX2SA-9V are supplied in tube packaging for surface mount assembly.

Q: Are there any temperature or environmental differences between these parts?

A: No. Both parts operate across the identical temperature range of -40°C to 85°C and feature sealed, fully enclosed construction with silver and gold contact materials.
