TX2SA-L2-9V-X Equivalent & Substitute Parts

Part Overview

The TX2SA-L2-9V-X is an active telecom relay manufactured by Panasonic Electric Works, configured as a DPDT (2 Form C) surface mount component with 2A contact rating and 9VDC coil voltage. This relay is designed for telecommunications applications requiring sealed, fully-rated switching performance across industrial temperature ranges. Substitute parts are identified to provide equivalent functional performance when the primary part number becomes unavailable or when alternative packaging configurations are required for specific assembly processes.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TX2SA-L2-9V-X is determined by strict equivalence across the following critical parameters:

• Coil voltage specification (9VDC)
• Contact configuration (DPDT / 2 Form C)
• Current rating (2 A)
• Coil type (Latching, Dual Coil)
• Mounting technology (Surface Mount)
• Termination style (Gull Wing)
• Seal rating (Sealed - Fully)
• Operating temperature range (-40°C ~ 85°C)
• Contact material composition (Silver/Gold)

The TX2SA-L2-9V substitute part maintains identical electrical and mechanical specifications. The primary distinction between the main part and its substitute is packaging configuration: the main part is supplied in Tape & Reel format, while the substitute is supplied in Tube packaging. Both parts share the same base product number (TX2SA) and are manufactured by Panasonic Electric Works with active product status.

Parameter Comparison

Engineering Selection Recommendations

Both the TX2SA-L2-9V-X and TX2SA-L2-9V are active products from Panasonic Electric Works with full regulatory compliance. The TX2SA-L2-9V-X maintains RoHS Compliance certification, while the TX2SA-L2-9V carries ROHS3 Compliance with REACH Unaffected status, indicating enhanced environmental compliance documentation.

Selection between these parts should be based on assembly process requirements. The Tape & Reel packaging (TX2SA-L2-9V-X) is optimized for automated pick-and-place assembly operations. The Tube packaging (TX2SA-L2-9V) is suitable for manual assembly processes or applications where reel-based feeding is not required. Both configurations deliver identical electrical performance and mechanical reliability for telecom relay applications.

Frequently Asked Questions (FAQ)

Q: Can TX2SA-L2-9V (Tube) be used as a direct replacement for TX2SA-L2-9V-X (Tape & Reel)?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. Substitution is valid provided the assembly process can accommodate Tube packaging instead of Tape & Reel format.

Q: What determines if a relay can substitute for the TX2SA-L2-9V-X?

A: A substitute relay must match all critical parameters: 9VDC coil voltage, DPDT contact configuration, 2A current rating, latching dual-coil type, surface mount technology, gull wing termination, full seal rating, and -40°C to 85°C operating range. Deviations in any of these parameters disqualify substitution.

Q: Are there compliance differences between the two part numbers?

A: The TX2SA-L2-9V-X is RoHS Compliant. The TX2SA-L2-9V carries ROHS3 Compliance with REACH Unaffected status. Both meet regulatory requirements; the substitute offers enhanced environmental compliance documentation.

Q: Does packaging affect the relay's electrical performance?

A: No. Tape & Reel and Tube packaging formats contain identical relay components. Packaging affects only handling, storage, and assembly process compatibility, not electrical or switching characteristics.

Q: What is the coil resistance specification used for?

A: The 405 Ohm coil resistance, combined with the 9VDC coil voltage specification, determines the coil current draw (22.2 mA). This parameter is critical for power supply design and circuit protection calculations.
