TN2-L2-H-12V Equivalent & Substitute Parts

Part Overview

The TN2-L2-H-12V is a general purpose relay manufactured by Panasonic Electric Works, featuring a DPDT (2 Form C) contact configuration with 1 A contact rating and 12VDC coil voltage. This through-hole mounted relay is designed for applications requiring dual-coil latching operation with sealed construction. The product is currently obsolete, making identification of compatible substitute components essential for system maintenance, repair, and redesign applications where continued availability is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TN2-L2-H-12V is determined by the following critical parameters:

• Coil Voltage: 12VDC (must match exactly for direct circuit compatibility)
• Contact Form: DPDT (2 Form C) (electrical switching topology requirement)
• Coil Type: Latching, Dual Coil (functional operation mode)
• Mounting Type: Through Hole (PCB assembly compatibility)
• Termination Style: PC Pin (connection interface)

The V23079B1203B301 qualifies as a substitute because it maintains identical specifications for all critical parameters listed above. While the substitute exhibits higher contact rating (2 A versus 1 A) and improved switching voltage capability (250VAC, 220VDC versus 125VAC, 110VDC), these represent enhanced performance characteristics that do not prevent substitution in applications designed for the original component.

Parameter Comparison

Engineering Selection Recommendations

The V23079B1203B301 is suitable for direct substitution in applications currently using the TN2-L2-H-12V. The substitute component maintains active product status with TE Connectivity, ensuring ongoing availability and supply chain continuity. The V23079B1203B301 is RoHS3 compliant, providing regulatory advantage over the obsolete original component. Both components share identical REACH and ECCN classifications (REACH Unaffected, EAR99), maintaining consistent export and compliance documentation requirements.

The substitute exhibits lower coil current consumption (11.7 mA versus 16.7 mA), which may provide marginal power efficiency benefits in applications with current-limited drive circuits. The higher contact rating and switching voltage of the substitute do not introduce incompatibility and provide additional safety margin for applications operating near the original component's electrical limits.

Frequently Asked Questions (FAQ)

Q: Can the V23079B1203B301 be used as a direct replacement for the TN2-L2-H-12V?

A: Yes. Both components share identical coil voltage (12VDC), contact form (DPDT), coil type (latching, dual coil), mounting type (through hole), and termination style (PC pin). These parameters determine functional compatibility in the circuit.

Q: What are the differences between these two relays?

A: The V23079B1203B301 provides higher contact current rating (2 A versus 1 A), higher maximum switching voltage (250VAC, 220VDC versus 125VAC, 110VDC), lower coil current draw (11.7 mA versus 16.7 mA), and extended operating temperature range (-40°C to 85°C versus -40°C to 70°C). Operate and release times are slightly longer (4 ms versus 3 ms).

Q: Are there any packaging differences?

A: The V23079B1203B301 is supplied in tube packaging, while the original TN2-L2-H-12V packaging format is not specified in available documentation. Both components use identical PC pin termination for through-hole PCB mounting.

Q: Does the substitute meet current regulatory requirements?

A: Yes. The V23079B1203B301 is RoHS3 compliant and maintains REACH Unaffected status, consistent with the original component's compliance classification.

Q: Will the higher coil resistance of the substitute affect circuit operation?

A: The substitute exhibits higher coil resistance (1.03 kOhms versus 720 Ohms) and lower coil current (11.7 mA versus 16.7 mA). Circuits designed for the original component's coil specifications should be verified to confirm adequate drive current availability for reliable relay operation.
