TN2-L2-3V Equivalent & Substitute Parts

Part Overview

The TN2-L2-3V is a general purpose relay manufactured by Panasonic Electric Works, featuring a DPDT (2 Form C) contact configuration with 1 A contact rating and 3 VDC coil voltage. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations.

The relay is designed for through-hole mounting with latching dual-coil operation, sealed construction, and PC pin termination. Given its obsolete status, substitute parts with compatible electrical and mechanical parameters are required for procurement and system continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TN2-L2-3V is determined by the following critical parameters:

• Coil voltage: 3 VDC (must match exactly)
• Contact form: DPDT (2 Form C) (must match exactly)
• Mounting type: Through Hole (must match exactly)
• Coil type: Latching, Dual Coil (must match exactly)
• Termination style: PC Pin (must match exactly)
• Must operate voltage: 2.25 VDC (must match exactly)

The substitute part V23079B1208B301 meets all critical substitution criteria. While the contact rating (2 A versus 1 A) and operating temperature range (-40°C to 85°C versus -40°C to 70°C) differ, these parameters represent improvements in capability and do not prevent functional substitution in applications designed for the TN2-L2-3V.

Parameter Comparison

Engineering Selection Recommendations

The V23079B1208B301 is suitable as a substitute for the obsolete TN2-L2-3V based on the following factors:

• Active product status ensures ongoing availability and supply chain continuity
• All critical electrical parameters match: 3 VDC coil voltage, DPDT contact configuration, 2.25 VDC must operate voltage, and latching dual-coil operation
• Mechanical compatibility is maintained through identical mounting type (through hole) and termination style (PC pin)
• The substitute provides enhanced specifications: higher contact rating (2 A versus 1 A) and extended operating temperature range (-40°C to 85°C versus -40°C to 70°C)
• RoHS3 compliance and REACH unaffected status align with modern regulatory requirements

Frequently Asked Questions (FAQ)

Q: Can the V23079B1208B301 directly replace the TN2-L2-3V in existing applications?

A: Yes. The substitute meets all critical substitution parameters: identical coil voltage (3 VDC), contact form (DPDT), mounting type (through hole), coil type (latching dual coil), termination style (PC pin), and must operate voltage (2.25 VDC). The higher contact rating and extended temperature range represent capability improvements.

Q: What is the significance of the different contact ratings (1 A versus 2 A)?

A: The TN2-L2-3V is rated for 1 A maximum contact current. The V23079B1208B301 is rated for 2 A. Applications designed for the original 1 A rating will operate within the substitute's specifications. The higher rating does not affect compatibility.

Q: Are there differences in coil resistance between these parts?

A: Yes. The TN2-L2-3V has 45 Ohms coil resistance; the V23079B1208B301 has 64 Ohms. Both meet the 2.25 VDC must operate voltage requirement. Coil resistance differences do not prevent substitution when the must operate voltage is satisfied.

Q: How do the operating time specifications compare?

A: The TN2-L2-3V operates and releases in 3 ms. The V23079B1208B301 operates and releases in 4 ms. This 1 ms difference is within typical relay performance variation and does not prevent functional substitution in general purpose applications.

Q: What is the impact of the extended operating temperature range?

A: The V23079B1208B301 operates from -40°C to 85°C, compared to the TN2-L2-3V range of -40°C to 70°C. The substitute provides a 15°C extension at the upper temperature limit, offering improved performance in higher temperature environments without affecting compatibility in the original operating range.

Q: Are there any compliance or certification differences?

A: The V23079B1208B301 carries RoHS3 compliance certification. Both parts are REACH unaffected and classified as EAR99. The substitute's active product status ensures compliance with current regulatory standards.
