AEP17012 Equivalent & Substitute Parts

Part Overview

The AEP17012 is a general purpose relay manufactured by Panasonic Electric Works, configured as a SPST-NO (1 Form A) with a 12VDC coil and 200A contact rating. This chassis mount relay is designed for applications requiring high current switching at 277VAC or 400VDC nominal switching voltage. The product is classified as "Not For New Designs," making identification of functionally equivalent alternatives necessary for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AEP17012 is determined by the following critical parameters:

• Coil Voltage: 12VDC (must match exactly for direct circuit compatibility)
• Contact Form: SPST-NO (1 Form A) (functional switching configuration)
• Coil Current: 500 mA (driver circuit compatibility)
• Coil Resistance: 24 Ohms (electrical load matching)
• Mounting Type: Chassis Mount (physical installation compatibility)
• Termination Style: Screw Terminal (connection method)
• Operating Temperature Range: -40°C ~ 80°C minimum (environmental suitability)
• Timing Characteristics: Operate Time 50 ms, Release Time 30 ms (system response requirements)

The AEVA1251 qualifies as a substitute based on matching all critical coil and functional parameters. While the AEVA1251 offers higher contact current rating (250A vs. 200A) and higher switching voltage capability (500VDC vs. 400VDC), these represent performance enhancements that do not compromise compatibility in applications designed for the AEP17012.

Parameter Comparison

Engineering Selection Recommendations

The AEVA1251 is the manufacturer-recommended substitute for the AEP17012. Both components are ROHS3 compliant and carry MSL rating of 1 (Unlimited), ensuring equivalent environmental and regulatory compliance.

The AEP17012 is designated "Not For New Designs," indicating end-of-life status. The AEVA1251 maintains "Active" product status, providing long-term availability and supply chain continuity for applications requiring 12VDC SPST-NO relay functionality.

Selection between these parts should be based on application requirements and supply availability. The AEVA1251 provides enhanced performance specifications (higher contact current rating and switching voltage capability) while maintaining identical coil parameters and timing characteristics, making it suitable for direct substitution in existing AEP17012 applications.

Frequently Asked Questions (FAQ)

Q: Can the AEVA1251 directly replace the AEP17012 in existing circuits?

A: Yes. Both relays share identical coil voltage (12VDC), coil current (500 mA), coil resistance (24 Ohms), contact form (SPST-NO), mounting type (Chassis Mount), and timing characteristics (50 ms operate, 30 ms release). The AEVA1251 provides equal or superior performance in all switching parameters.

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

A: The AEVA1251 offers higher contact current rating (250A vs. 200A) and higher nominal switching voltage (500VDC vs. 400VDC). The AEVA1251 also has a lower must-release voltage (0.5VDC vs. 1VDC) and slightly extended operating temperature range (-40°C to 85°C vs. -40°C to 80°C). The AEP17012 is obsolete; the AEVA1251 is in active production.

Q: Are there packaging differences between these parts?

A: Yes. The AEP17012 is supplied in Bulk packaging, while the AEVA1251 is supplied in Tray packaging. Both use Screw Terminal termination, though the AEP17012 includes wire leads as an additional option.

Q: Do both relays meet the same compliance standards?

A: Yes. Both the AEP17012 and AEVA1251 are ROHS3 compliant with MSL rating of 1 (Unlimited), ensuring equivalent environmental and regulatory compliance for industrial applications.

Q: Which relay should be selected for new applications?

A: The AEVA1251 should be selected for new applications. It is the active, manufacturer-recommended substitute with superior performance specifications and ongoing supply availability.
