TX2SL-3V Equivalent & Substitute Parts Reference

Part Overview

The TX2SL-3V is a telecom relay manufactured by Panasonic Electric Works, featuring DPDT (2 Form C) contact configuration with 2A contact rating and 3VDC coil voltage. This surface mount component is designed for telecommunications applications with sealed, fully enclosed construction. The TX2SL-3V is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TX2SL-3V are classified into two categories based on parametric equivalence:

Parametric Equivalents (TX2SA-3V, TX2SS-3V): These Panasonic Electric Works relays maintain identical electrical and mechanical specifications across all critical parameters: 3VDC coil voltage, DPDT contact form, 2A contact rating, 220VDC maximum switching voltage, 46.7 mA coil current, 4 ms operate and release times, -40°C to 85°C operating temperature range, and gull wing termination. Both are active products with full seal rating and identical contact material composition. The primary distinction is packaging format and inventory availability.

Similar Equivalent (V23079D1008B301): The TE Connectivity Potter & Brumfield V23079D1008B301 provides functional equivalence with matching coil voltage, contact form, current rating, coil current, timing characteristics, and operating temperature range. This part is classified as a general purpose relay rather than telecom-specific, with contact material specified as Silver Nickel (AgNi) and Gold (Au) instead of pure Silver and Gold. Maximum switching voltage extends to 250VAC in addition to 220VDC. Coil resistance is 64 Ohms versus 64.3 Ohms for the TX2SL-3V.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: TX2SA-3V and TX2SS-3V are the primary substitutes for TX2SL-3V. Both maintain identical electrical specifications and are active products with current manufacturing support. TX2SA-3V and TX2SS-3V are both ROHS3 compliant, providing regulatory advantage over the obsolete TX2SL-3V. Selection between these two parametric equivalents depends on packaging requirements and inventory availability.

For Cross-Manufacturer Substitution: V23079D1008B301 from TE Connectivity Potter & Brumfield provides functional equivalence with all critical electrical parameters matching the TX2SL-3V. This part is RoHS compliant and active. The contact material composition differs (Silver Nickel versus pure Silver), and the seal rating is not specified. The V23079D1008B301 supports both 250VAC and 220VDC switching, providing extended voltage capability. This part is suitable for applications where cross-manufacturer sourcing is acceptable and the contact material variation does not impact circuit performance.

Frequently Asked Questions (FAQ)

Q: Can TX2SA-3V and TX2SS-3V be used interchangeably with TX2SL-3V?

A: Yes. Both TX2SA-3V and TX2SS-3V are parametric equivalents with identical electrical and mechanical specifications. The primary differences are packaging format (tube) and inventory levels. Both are active products with current manufacturing support, making them suitable direct replacements for the obsolete TX2SL-3V.

Q: What is the difference between the Panasonic TX2SA-3V/TX2SS-3V and the TE Connectivity V23079D1008B301?

A: All three parts share identical coil voltage, contact form, current rating, coil current, timing, and operating temperature specifications. The V23079D1008B301 differs in contact material composition (Silver Nickel and Gold versus Silver and Gold), relay classification (general purpose versus telecom), and extended switching voltage capability (250VAC addition). The V23079D1008B301 seal rating is not specified, whereas the Panasonic parts are fully sealed.

Q: Are there packaging considerations when substituting these relays?

A: Yes. TX2SA-3V and TX2SS-3V are supplied in tube packaging, while V23079D1008B301 is supplied in tape and reel format. Tube packaging is suitable for manual assembly and lower-volume applications, while tape and reel is optimized for automated pick-and-place assembly. Verify your assembly process requirements before selecting a substitute.

Q: Do all substitute parts meet RoHS compliance?

A: TX2SA-3V and TX2SS-3V are ROHS3 compliant. V23079D1008B301 is RoHS compliant. The original TX2SL-3V RoHS status is not specified. All three substitutes meet current RoHS regulatory requirements.

Q: What is the coil resistance tolerance between these parts?

A: TX2SL-3V, TX2SA-3V, and TX2SS-3V all specify 64.3 Ohms coil resistance. V23079D1008B301 specifies 64 Ohms, a 0.3 Ohm difference. This variation is negligible for circuit design purposes and does not affect functional equivalence.

Q: Can V23079D1008B301 be used in applications requiring sealed relay construction?

A: The V23079D1008B301 seal rating is not specified in the provided data. If sealed construction is a design requirement, TX2SA-3V or TX2SS-3V are the appropriate selections, as both are fully sealed relays matching the TX2SL-3V specification.
