Substitute Part Grouping Explanation

Substitute parts within the TX-S series are classified as parametric equivalents when all critical electrical and mechanical parameters match the main part number TXS2SL-3V-X. The substitution logic is based on the following key parameters that determine functional interchangeability:

Coil Voltage: 3VDC
Contact Form: DPDT (2 Form C)
Contact Rating: 1 A
Switching Voltage: 110VDC - Max
Coil Current: 16.7 mA
Coil Type: Non Latching
Mounting Type: Surface Mount
Termination Style: Gull Wing
Seal Rating: Sealed - Fully
Operating Temperature Range: -40°C ~ 70°C
Contact Material: Silver (Ag), Gold (Au)
Coil Resistance: 180 Ohms
Must Operate Voltage: 2.4 VDC

Engineering Selection Recommendations

All three part numbers—TXS2SL-3V-X, TXS2SA-3V-Z, and TXS2SS-3V-Z—are classified as Active product status and maintain full compliance with environmental regulations. TXS2SA-3V-Z and TXS2SS-3V-Z carry ROHS3 Compliant certification with REACH Unaffected status, providing enhanced regulatory alignment for applications requiring stricter compliance documentation. Selection between these equivalents should be based on inventory availability, supply chain lead times, and specific compliance documentation requirements for the end application. All three parts are suitable for direct substitution in DPDT relay applications operating at 3VDC with 1A contact rating and surface mount gull wing termination.

Frequently Asked Questions (FAQ)

Q: Can TXS2SA-3V-Z or TXS2SS-3V-Z be used as direct replacements for TXS2SL-3V-X?

A: Yes. All three part numbers share identical electrical specifications, contact ratings, coil parameters, and mechanical mounting characteristics. They are functionally interchangeable in circuit applications.

Q: What is the difference between the three part numbers?

A: The part numbers differ in internal construction designation or manufacturing lot coding within the TX-S series. All electrical and mechanical parameters remain identical. TXS2SA-3V-Z and TXS2SS-3V-Z carry ROHS3 Compliant certification versus RoHS Compliant for TXS2SL-3V-X.

Q: Are there any compatibility concerns with PCB layout or footprint?

A: No. All three parts use identical Surface Mount gull wing termination style and are designed for the same PCB footprint pattern.

Q: What is the operating voltage range for these relays?

A: The coil operates at 3VDC nominal. Must Operate Voltage is 2.4 VDC and Must Release Voltage is 0.3 VDC. Maximum switching voltage across contacts is 110VDC.

Q: Can these relays be used in applications requiring REACH compliance?

A: TXS2SA-3V-Z and TXS2SS-3V-Z are classified as REACH Unaffected. TXS2SL-3V-X compliance status for REACH is not specified in the provided data.

Q: What is the coil power consumption?

A: Coil current is 16.7 mA at 3VDC nominal, with coil resistance of 180 Ohms. Power consumption is approximately 50.1 mW.

Q: What are the switching speed characteristics?

A: Operate Time and Release Time are both 5 ms for all three part numbers.
