AHN12012 Equivalent & Substitute Parts

Part Overview

The AHN12012 is a general purpose relay manufactured by Panasonic Electric Works, featuring a Single Pole Double Throw (SPDT) contact configuration with a 12VDC coil. This socketable relay is rated for 16A switching capacity and is designed for non-latching operation in industrial control applications. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance and component replacement in existing installations.

Key Parameters

Substitute Part Grouping Explanation

The Finder Relays 40.61.9.012.0000 qualifies as a direct substitute for the AHN12012 based on the following critical parameters:

• Coil Voltage: Both parts operate at 12VDC
• Contact Configuration: Both feature SPDT (1 Form C) contact form
• Current Rating: Both are rated for 16A switching capacity
• Mounting Architecture: Both utilize socketable, plug-in termination
• Coil Operation: Both employ non-latching coil type
• Electrical Classification: Both are general purpose relays

The 40.61.9.012.0000 maintains functional equivalence across all primary switching parameters while offering enhanced performance characteristics in secondary specifications.

Parameter Comparison

Engineering Selection Recommendations

The Finder Relays 40.61.9.012.0000 is a qualified substitute for the obsolete AHN12012. Both parts share identical primary electrical specifications: 12VDC coil voltage, SPDT contact configuration, and 16A current rating with socketable plug-in termination.

The Finder part demonstrates superior performance in secondary parameters: higher maximum switching voltage (400VAC versus 250VAC), increased load capacity (6400VA versus 4000VA), faster switching times (7ms operate, 3ms release versus 15ms and 5ms), and extended operating temperature range (-40°C to 85°C versus -40°C to 70°C).

Both parts maintain current regulatory compliance. The AHN12012 holds cURus and VDE certifications with RoHS compliance. The 40.61.9.012.0000 carries broader certification coverage including CCC, CSA, cURus, EAC, ENEC, RINA, and VDE, with ROHS3 compliance and REACH unaffected status.

Socket compatibility and plug-in termination are identical between both parts, ensuring direct mechanical and electrical interchangeability in existing relay base installations.

Frequently Asked Questions (FAQ)

Q: Can the Finder 40.61.9.012.0000 directly replace the Panasonic AHN12012 in existing applications?

A: Yes. Both relays share identical coil voltage (12VDC), contact configuration (SPDT), current rating (16A), and socketable plug-in termination. Direct substitution is electrically and mechanically compatible.

Q: What are the key differences between these two relays?

A: The Finder part offers enhanced specifications: maximum switching voltage of 400VAC (versus 250VAC), higher load capacity of 6400VA (versus 4000VA), faster switching response times, and a wider operating temperature range to 85°C. Contact material differs: Silver Nickel in the Panasonic versus Silver Cadmium Oxide in the Finder.

Q: Are there any compliance or certification concerns with substitution?

A: No. Both parts are obsolete and maintain appropriate regulatory certifications. The Finder part carries additional certifications (CCC, EAC, ENEC, RINA) and ROHS3 compliance, providing equivalent or superior compliance status.

Q: Will the Finder relay fit in the existing socket base?

A: Yes. Both relays utilize identical socketable mounting architecture with plug-in termination, ensuring physical compatibility with existing relay bases designed for the AHN12012.

Q: Are there any coil current or resistance differences that affect circuit design?

A: The Finder part draws 55mA coil current (versus 44.4mA) with 220 Ohm coil resistance (versus 270 Ohms). These differences are minor and do not require circuit redesign in standard control applications. Verify coil supply capacity if operating near current limits.
