TXD2SA-12V-Z Equivalent & Substitute Parts

Part Overview

The TXD2SA-12V-Z is a general purpose relay manufactured by Panasonic Electric Works, configured as a DPDT (2 Form C) surface mount component with a 12VDC coil. This relay is designed for applications requiring dual-pole, dual-throw switching functionality at 2A contact rating. The part is currently active in production with full RoHS compliance and sealed construction suitable for industrial and commercial environments. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the TX-D series, ensuring functional interchangeability within specified operating conditions.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TXD2SA-12V-Z are identified within the TX-D series based on strict equivalence of the following critical parameters:

• Coil voltage: 12VDC
• Contact form: DPDT (2 Form C)
• Contact rating: 2 A
• Switching voltage: 220VDC maximum
• Mounting type: Surface Mount
• Termination style: Gull Wing
• Coil resistance: 720 Ohms
• Coil current: 16.7 mA
• Operating temperature range: -40°C to 85°C
• Seal rating: Sealed - Fully
• Contact material: Silver (Ag), Gold (Au)

Parts meeting all these parameters are classified as parametric equivalents and may be substituted without modification to circuit design or PCB layout. Variations in base product number (suffix designation) within the TX-D series do not affect functional compatibility when all electrical and mechanical parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both the TXD2SA-12V-Z and TXD2SS-12V-Z are active production parts from Panasonic Electric Works with full RoHS compliance and identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability and supply chain considerations. Both parts carry ECCN EAR99 classification and HTSUS 8536.41.0020 tariff code. The TXD2SA-12V-Z currently maintains higher inventory levels (2100 pcs) compared to the TXD2SS-12V-Z (1882 pcs), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can TXD2SS-12V-Z be used as a direct replacement for TXD2SA-12V-Z?

A: Yes. Both parts are parametric equivalents with identical coil voltage, contact form, current rating, switching voltage, timing characteristics, and operating temperature range. No circuit or PCB modifications are required.

Q: What determines if a part is a valid substitute for the TXD2SA-12V-Z?

A: A substitute must maintain equivalence across all critical parameters: 12VDC coil voltage, DPDT contact form, 2A contact rating, 220VDC maximum switching voltage, 720 Ohm coil resistance, 16.7 mA coil current, surface mount configuration with gull wing termination, and -40°C to 85°C operating temperature range.

Q: Are there packaging differences between TXD2SA-12V-Z and TXD2SS-12V-Z?

A: Both parts are supplied in Tape & Reel (TR) packaging, which is the standard surface mount delivery format for these relays.

Q: What is the difference between the base product numbers TXD2 and TXD2SS?

A: The base product number suffix designates internal construction or manufacturing variant within the TX-D series. When all electrical and mechanical parameters are identical, these variants are functionally interchangeable.

Q: Are both parts suitable for the same temperature range applications?

A: Yes. Both TXD2SA-12V-Z and TXD2SS-12V-Z operate across the identical temperature range of -40°C to 85°C with the same must-operate and must-release voltage specifications.
