ACV11012 Equivalent & Substitute Parts

Part Overview

The ACV11012 is an automotive SPDT relay manufactured by Panasonic Electric Works, rated for 20A at 12VDC. This part is classified as obsolete, making equivalent substitutes necessary for ongoing system maintenance and new designs. The relay features non-latching coil operation, socketable mounting, and plug-in termination suitable for automotive applications. Cadmium-free silver alloy contacts ensure environmental compliance while maintaining reliable switching performance across the operating temperature range of -40°C to 85°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ACV11012 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Contact form must be SPDT (1 Form C)
• Coil voltage must be 12VDC
• Mounting type must be socketable
• Termination style must be plug-in
• Operating temperature range must encompass -40°C to 85°C

Secondary Compatibility Criteria:

• Contact rating current must be equal to or greater than 20A
• Coil current must not exceed system drive capability
• Switching voltage must be compatible with 14VDC nominal automotive systems
• Must operate and release voltages must support 12VDC coil operation

The CM1-12V meets all primary and secondary criteria, with enhanced contact rating (35A) and sealed construction providing improved reliability for automotive environments.

Parameter Comparison

Engineering Selection Recommendations

The CM1-12V is a direct functional substitute for the ACV11012. Both relays share identical contact form, coil voltage, mounting configuration, and operating temperature specifications. The CM1-12V offers superior contact current rating (35A versus 20A), providing design margin for applications requiring the ACV11012.

The CM1-12V carries active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The sealed construction of the CM1-12V provides enhanced environmental protection compared to the ACV11012, making it suitable for demanding automotive applications.

The increased coil current requirement (125mA versus 67mA) must be verified against the system's relay drive circuit capability. The higher must-release voltage (1.2VDC versus 0.6VDC) remains within acceptable automotive electrical system parameters.

Frequently Asked Questions (FAQ)

Q: Can the CM1-12V directly replace the ACV11012 in existing designs?

A: Yes. Both relays feature identical SPDT contact form, 12VDC coil voltage, socketable mounting, and plug-in termination. The CM1-12V's higher contact rating (35A) and sealed construction provide equivalent or improved performance. Verify that the relay drive circuit can supply the increased coil current (125mA).

Q: What is the primary difference between these two relays?

A: The CM1-12V provides higher contact current rating (35A versus 20A) and sealed construction. The CM1-12V requires higher coil current (125mA versus 67mA) and has a higher must-release voltage (1.2VDC versus 0.6VDC). Both operate identically at 12VDC with 10ms switching times.

Q: Is the CM1-12V suitable for automotive applications?

A: Yes. The CM1-12V is designed for automotive use with sealed construction, cadmium-free silver alloy contacts, and operating temperature range of -40°C to 85°C. ROHS3 compliance ensures regulatory compliance for current automotive standards.

Q: What packaging is available for the CM1-12V?

A: The CM1-12V is supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: Are there any coil drive considerations when switching from ACV11012 to CM1-12V?

A: Yes. The CM1-12V requires 125mA coil current compared to 67mA for the ACV11012. Confirm that the relay drive circuit can supply this increased current without exceeding design limits.
