TX2SS-48V Telecom Relay Equivalent & Substitute Parts

Part Overview

The TX2SS-48V is an active Panasonic Electric Works telecom relay featuring DPDT (2 Form C) contact configuration with 2A switching capacity at 48VDC coil voltage. This surface mount component is designed for telecom applications requiring sealed, fully isolated switching with non-latching operation. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, ensuring functional interchangeability in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TX2SS-48V is determined by strict equivalence across the following critical parameters:

• Coil voltage: 48VDC
• Contact form: DPDT (2 Form C)
• Contact rating: 2 A minimum
• Switching voltage: 220VDC maximum
• Mounting type: Surface Mount
• Termination style: Gull Wing
• Seal rating: Sealed - Fully
• Operating temperature range: -40°C ~ 70°C
• Coil type: Non Latching
• Contact material composition: Silver (Ag), Gold (Au)

The TX2SA-48V meets all specified parameters and qualifies as a parametric equivalent within the TX series telecom relay family.

Parameter Comparison

Engineering Selection Recommendations

Both TX2SS-48V and TX2SA-48V are active products from Panasonic Electric Works with identical RoHS compliance and export classification (EAR99). Selection between these parts should be based on availability and application-specific inventory requirements. The TX2SA-48V currently maintains higher stock levels (2083 pcs vs. 1095 pcs), which may influence procurement decisions for high-volume applications. Both components satisfy identical electrical and mechanical specifications for 48VDC telecom relay applications requiring DPDT switching with 2A contact rating.

Frequently Asked Questions (FAQ)

Q: Can TX2SA-48V replace TX2SS-48V in existing designs? A: Yes. Both parts are parametrically equivalent across all critical electrical and mechanical specifications, including coil voltage, contact configuration, current rating, switching voltage, operating temperature range, and termination style.

Q: Are there differences in contact material or seal rating between these parts? A: No. Both parts feature identical silver (Ag) and gold (Au) contact material composition and fully sealed construction.

Q: Do both parts meet the same compliance standards? A: Yes. Both TX2SS-48V and TX2SA-48V are RoHS compliant with EAR99 export classification and identical HTSUS coding.

Q: What is the difference between the TX2SS and TX2SA base product numbers? A: The base product numbers (TX2SS vs. TX2SA) indicate different internal design variants within the TX series. However, when specified with identical coil voltage (48V), contact form (DPDT), and all other parameters, they function as electrical equivalents.

Q: Are the operating and release times identical? A: Yes. Both parts operate and release in 4 ms, with identical must-operate voltage (36 VDC) and must-release voltage (4.8 VDC) specifications.
