Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TX2SL-L2-9V is determined by strict alignment of the following critical parameters:

• Coil voltage: 9VDC
• Contact configuration: DPDT (2 Form C)
• Contact current rating: 2 A minimum
• Mounting type: Surface Mount
• Termination style: Gull Wing
• Coil type: Latching, Dual Coil
• Operating temperature range: -40°C ~ 85°C minimum
• Switching voltage capability: 220VDC or higher

The V23079E1206B301 from TE Connectivity Potter & Brumfield Relays meets all substitution criteria. This general purpose relay maintains functional equivalence across all critical electrical and mechanical parameters while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The V23079E1206B301 is the qualified substitute for TX2SL-L2-9V applications. Selection is based on:

• Functional parameter equivalence across all critical electrical specifications
• Active product status ensuring long-term availability and supply chain continuity
• RoHS compliance certification of the substitute part
• Identical contact configuration, coil voltage, and switching characteristics
• Matching operating temperature range and timing specifications
• Surface mount gull wing termination compatibility with existing PCB layouts

The substitute part demonstrates lower coil current consumption (15.6 mA versus 22.2 mA), which represents an operational advantage in power-sensitive applications. Contact material composition differs slightly (AgNi versus Ag in the substitute), but both configurations maintain the required contact rating and switching voltage specifications.

Frequently Asked Questions (FAQ)

Q: Can V23079E1206B301 directly replace TX2SL-L2-9V in existing designs?

A: Yes. Both relays share identical coil voltage (9VDC), contact configuration (DPDT), current rating (2A), mounting type (surface mount), and termination style (gull wing). PCB footprints and electrical performance are compatible.

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

A: The V23079E1206B301 operates at 15.6 mA compared to 22.2 mA for the TX2SL-L2-9V. This lower current consumption in the substitute part reduces power dissipation and driver circuit loading without affecting switching performance.

Q: Are there packaging differences between these relays?

A: The TX2SL-L2-9V uses standard packaging, while the V23079E1206B301 is supplied in Tape & Reel (TR) format. Both are surface mount components with gull wing termination suitable for automated assembly.

Q: What is the significance of the coil resistance difference?

A: The V23079E1206B301 has 578 Ohms coil resistance versus 405 Ohms for the TX2SL-L2-9V. Both maintain the same 6.75 VDC must-operate voltage specification, ensuring compatible driver circuit performance.

Q: Does the substitute part meet current compliance standards?

A: The V23079E1206B301 is RoHS compliant and carries EAR99 ECCN classification, matching the regulatory status of the original part. The substitute is an active product with current manufacturing support.

Q: Are the switching voltage ratings equivalent?

A: The V23079E1206B301 supports 250VAC and 220VDC maximum switching voltage, exceeding the 220VDC specification of the TX2SL-L2-9V. This provides equivalent or superior performance for DC switching applications.
