TN2-H-12V Equivalent & Substitute Parts

Part Overview

The TN2-H-12V is a general purpose relay manufactured by Panasonic Electric Works, configured as a DPDT (2 Form C) with 1A contact rating and 12VDC coil voltage. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations. The relay features through-hole mounting with PC pin termination, sealed construction, and operates across -40°C to 70°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TN2-H-12V is determined by the following critical parameters that must remain constant or compatible:

• Contact Form: DPDT (2 Form C) configuration required for identical switching functionality
• Coil Voltage: 12VDC nominal operating voltage
• Coil Current: 11.7 mA draw specification
• Mounting Type: Through hole with PC pin termination for PCB compatibility
• Coil Type: Non-latching operation
• Contact Rating: Minimum 1A current handling capability

Two substitute parts meet these criteria with varying degrees of parameter alignment:

AGN20012 (Panasonic Electric Works): Active product status with identical electrical specifications and enhanced operating temperature range (-40°C to 85°C). Packaging format is tube. Contact material differs (AgPd/Au vs Ag/Au).

D3202 (TE Connectivity Potter & Brumfield Relays): Obsolete telecom relay with higher contact rating (2A vs 1A) and elevated switching voltage capability (250VAC/220VDC vs 125VAC/110VDC). Operate and release times differ slightly. Coil specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

AGN20012 is the primary substitute for new designs and ongoing applications. This part maintains identical electrical specifications (coil voltage, current, and resistance) while offering active product status, ensuring long-term availability and supply chain stability. The extended operating temperature range (-40°C to 85°C) provides additional thermal margin. RoHS3 compliance supports modern manufacturing and environmental standards. Packaging in tube format accommodates automated assembly processes.

D3202 serves as an alternative where higher contact current capacity (2A) and elevated switching voltage (250VAC/220VDC) are beneficial for margin or future design flexibility. However, this part shares obsolete status with the original TN2-H-12V, limiting its suitability for new implementations. The slightly increased operate and release times (4ms vs 3ms) may impact timing-critical applications.

Both substitutes maintain through-hole PC pin termination, ensuring direct PCB footprint compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can AGN20012 replace TN2-H-12V in existing designs without modification?

A: Yes. AGN20012 maintains identical contact form (DPDT), coil voltage (12VDC), coil current (11.7mA), and coil resistance (1.03kOhms). Through-hole PC pin termination is identical. The 1ms increase in operate and release time is within typical relay tolerance bands for general purpose applications.

Q: What is the primary difference between AGN20012 and D3202?

A: AGN20012 is an active Panasonic product with identical 1A contact rating. D3202 is an obsolete TE Connectivity part with doubled contact rating (2A) and higher switching voltage capability (250VAC/220VDC vs 125VAC/110VDC). Both maintain 12VDC coil specifications and DPDT configuration.

Q: Does AGN20012 require different PCB footprint or mounting?

A: No. AGN20012 uses identical through-hole PC pin termination as TN2-H-12V. No PCB layout changes are required.

Q: Why is AGN20012 preferred over D3202 for new designs?

A: AGN20012 carries active product status, ensuring availability and supply continuity. D3202 is obsolete, presenting long-term sourcing risk. For applications requiring only 1A contact rating, AGN20012 provides equivalent performance with superior lifecycle support.

Q: Are there compliance differences between these parts?

A: AGN20012 is RoHS3 compliant and carries REACH Unaffected status. Both TN2-H-12V and D3202 are REACH Unaffected. All three parts carry EAR99 ECCN classification and identical HTSUS code (8536.41.0020).

Q: What is the operating temperature consideration?

A: TN2-H-12V operates -40°C to 70°C. Both AGN20012 and D3202 extend to -40°C to 85°C, providing 15°C additional upper margin. For applications approaching 70°C ambient, substitutes offer thermal headroom.
