AHN22112 Equivalent & Substitute Parts

Part Overview

The AHN22112 is a general purpose relay manufactured by Panasonic Electric Works, featuring a DPDT (2 Form C) contact configuration with a 12VDC coil. This socketable relay is designed for applications requiring 5A switching capacity at 250VAC or 30VDC maximum. The product is currently obsolete, making equivalent substitute parts necessary for system maintenance, repair, and legacy equipment support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AHN22112 is determined by the following critical parameters:

• Coil Voltage: Must be 12VDC to ensure direct compatibility with existing control circuits
• Contact Form: Must be DPDT (2 Form C) to maintain circuit switching topology
• Mounting Type: Must be socketable with plug-in termination for mechanical and electrical compatibility
• Contact Rating: Minimum 5A at 250VAC or 30VDC to support the original application load
• Operating Temperature Range: Must encompass -40°C to 70°C to function within specified environmental conditions
• RoHS Compliance: Required for regulatory and supply chain continuity

The RRM002D12V from Carlo Gavazzi Inc. meets all critical substitution criteria. While it provides enhanced specifications (10A contact rating, higher switching capacity), these represent functional improvements rather than deviations from the core requirements.

Parameter Comparison

Engineering Selection Recommendations

The RRM002D12V is a direct functional substitute for the AHN22112. Both relays are obsolete products with RoHS compliance, ensuring regulatory alignment for legacy system maintenance.

The RRM002D12V provides higher contact current rating (10A versus 5A) and increased switching capacity (2500VA, 300W versus 1250VA, 150W). These enhanced specifications do not create incompatibility; they provide additional margin for the original application requirements.

Approval certifications differ between the two parts. The AHN22112 carries cURus and VDE approvals, while the RRM002D12V carries CE, CSA, and UR approvals. Both certifications are recognized for industrial relay applications. Verification of certification requirements for your specific end-use application is necessary prior to implementation.

Frequently Asked Questions (FAQ)

Q: Can the RRM002D12V directly replace the AHN22112 in existing equipment?

A: Yes. Both relays share identical coil voltage (12VDC), contact form (DPDT), mounting type (socketable), and termination style (plug-in). The RRM002D12V meets or exceeds all electrical parameters of the AHN22112.

Q: Why does the RRM002D12V have a higher current rating?

A: The RRM002D12V is rated for 10A contact current compared to the AHN22112's 5A rating. This represents a design difference between manufacturers and does not prevent substitution. The higher rating provides additional capacity margin for the application.

Q: Are there packaging differences between these relays?

A: The AHN22112 is supplied in tube packaging, while the RRM002D12V is supplied in bulk packaging. Both are socketable relays with identical plug-in termination, ensuring mechanical compatibility in the socket.

Q: Do the different approval agencies affect substitution?

A: The AHN22112 carries cURus and VDE approvals; the RRM002D12V carries CE, CSA, and UR approvals. Both sets of certifications are recognized for industrial relay applications. Confirm that the substitute part's certifications meet your equipment's regulatory requirements.

Q: What is the operating temperature range for both relays?

A: Both the AHN22112 and RRM002D12V operate across -40°C to 70°C, ensuring identical thermal performance in the specified environment.
