TXS2SA-1.5V-X Equivalent & Substitute Parts

Part Overview

The TXS2SA-1.5V-X is a general purpose relay manufactured by Panasonic Electric Works, featuring DPDT (2 Form C) contact configuration with 1 A contact rating and 1.5 VDC coil voltage. This surface mount relay operates at low voltage and is designed for applications requiring sealed, fully protected switching contacts. The part is currently active in production with 1053 units in stock.

Substitute parts are identified when equivalent electrical performance can be maintained across critical switching parameters while accommodating different coil voltage requirements in system designs.

Key Parameters

Substitute Part Grouping Explanation

The TXS2SA-1.5V-X can be substituted with TXS2SA-6V based on the following criteria:

Both parts share identical electrical and mechanical characteristics across all critical switching parameters:

• Same contact form (DPDT / 2 Form C)
• Same contact rating (1 A)
• Same maximum switching voltage (110 VDC)
• Same mounting type (Surface Mount)
• Same termination style (Gull Wing)
• Same seal rating (Sealed - Fully)
• Same operating temperature range (-40°C to 70°C)
• Same contact material composition (Silver and Gold)
• Same coil type (Non Latching)
• Same relay type (General Purpose)

The primary difference is coil voltage: TXS2SA-1.5V-X operates at 1.5 VDC, while TXS2SA-6V operates at 6 VDC. Substitution is valid only when the system power supply and control circuit voltage can accommodate the alternative coil voltage requirement.

Parameter Comparison

Engineering Selection Recommendations

Both TXS2SA-1.5V-X and TXS2SA-6V are active production parts with full RoHS compliance. The TXS2SA-1.5V-X carries RoHS Compliant status, while TXS2SA-6V carries ROHS3 Compliant status with REACH Unaffected designation.

Selection between these parts depends solely on system coil voltage requirements. The TXS2SA-1.5V-X requires 1.5 VDC operation with a must-operate threshold of 1.2 VDC. The TXS2SA-6V requires 6 VDC operation with a must-operate threshold of 4.8 VDC. Both parts deliver identical contact switching performance and thermal operating range.

Packaging differs: TXS2SA-1.5V-X is supplied in Tape & Reel format, while TXS2SA-6V is supplied in Tube format. This distinction affects procurement and assembly processes but does not impact electrical performance.

Frequently Asked Questions (FAQ)

Q: Can TXS2SA-6V replace TXS2SA-1.5V-X in any application?

A: Substitution is valid only when the control circuit power supply can provide 6 VDC to the relay coil. The contact switching characteristics are identical, but coil voltage requirements differ. Direct substitution without circuit modification is not possible if the system is designed for 1.5 VDC operation.

Q: What are the critical parameters that must match for substitution?

A: Contact form (DPDT), contact rating (1 A), maximum switching voltage (110 VDC), mounting type (Surface Mount), termination style (Gull Wing), seal rating (Sealed - Fully), and operating temperature range (-40°C to 70°C) must remain constant. Coil voltage is the only parameter that can differ between equivalent parts.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel and Tube packaging formats do not affect relay electrical performance. Packaging selection is determined by assembly process requirements and procurement logistics.

Q: Are both parts compliant with current environmental regulations?

A: Yes. TXS2SA-1.5V-X is RoHS Compliant. TXS2SA-6V is ROHS3 Compliant with REACH Unaffected status. Both parts meet current environmental compliance requirements.

Q: What is the difference in coil current between these parts?

A: TXS2SA-1.5V-X draws 33.3 mA at 1.5 VDC. TXS2SA-6V draws 8.3 mA at 6 VDC. The higher coil resistance in TXS2SA-6V (720 Ohms versus 45 Ohms) results in lower current draw at higher voltage, affecting power supply design and circuit protection requirements.
