VF7-41F11 Equivalent & Substitute Parts

Part Overview

The VF7-41F11 is an automotive SPST relay manufactured by TE Connectivity Potter & Brumfield Relays, designed for 12VDC applications with a 70A contact rating. This relay operates as a non-latching, single-pole single-throw (SPST-NO) device with socketable mounting and quick-connect termination. The product is classified as obsolete, necessitating identification of functionally equivalent alternatives for continued system support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the VF7-41F11 is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Coil voltage: 12VDC
• Contact form: SPST-NO (1 Form A)
• Contact rating: 70 A minimum
• Switching voltage: 14VDC nominal
• Coil type: Non-latching operation
• Termination compatibility: Quick-connect 0.250" standard

The CB1AH-M-12V from Panasonic Electric Works satisfies all mandatory electrical parameters. Differences in mounting type (socketable versus chassis mount), operating temperature upper limit (125°C versus 85°C), and coil power consumption (1.6W versus 1.8W) represent secondary variations that do not preclude functional substitution in applications within the overlapping temperature range of -40°C to 85°C.

Parameter Comparison

Engineering Selection Recommendations

The CB1AH-M-12V is a functionally equivalent substitute for the obsolete VF7-41F11 based on electrical parameter alignment. Both relays operate at 12VDC with identical 70A contact ratings and SPST-NO contact configuration.

Compliance and Certification Status:

• VF7-41F11: REACH Unaffected, ECCN EAR99
• CB1AH-M-12V: REACH Unaffected, ECCN EAR99, RoHS3 Compliant

The CB1AH-M-12V provides enhanced regulatory compliance through RoHS3 certification and active product status, ensuring continued availability and manufacturer support. The substitute operates within the overlapping temperature range of -40°C to 85°C, suitable for automotive applications within this envelope.

Application Constraints: Applications requiring operation above 85°C or demanding the faster switching response of the original VF7-41F11 (7 ms operate time, 2 ms release time) must evaluate the 15 ms switching times of the CB1AH-M-12V for compatibility with system timing requirements.

Frequently Asked Questions (FAQ)

Q: Can the CB1AH-M-12V directly replace the VF7-41F11 in all applications?

A: The CB1AH-M-12V is electrically equivalent for coil voltage, contact rating, and switching voltage. However, applications operating above 85°C ambient temperature or requiring the faster switching response of the original relay (7 ms operate, 2 ms release versus 15 ms for the substitute) require evaluation against specific system requirements.

Q: What is the difference in mounting between these relays?

A: The VF7-41F11 uses socketable mounting, while the CB1AH-M-12V is chassis-mount. Physical installation methods differ, requiring mechanical redesign or adapter solutions for direct substitution in existing socket-based assemblies.

Q: Are the termination styles compatible?

A: Both relays use quick-connect termination at 0.250" (6.3mm) standard. The CB1AH-M-12V additionally supports 0.375" termination. Existing 0.250" quick-connect terminals are compatible with the substitute.

Q: How do the switching times affect system performance?

A: The CB1AH-M-12V operates at 15 ms for both operate and release times, compared to 7 ms operate and 2 ms release for the VF7-41F11. Applications with timing-critical control logic must verify that the slower response meets system specifications.

Q: What is the significance of the different contact materials?

A: The VF7-41F11 uses Silver Nickel (AgNi) contacts, while the CB1AH-M-12V uses Silver Alloy with cadmium-free composition. Both materials are suitable for automotive 70A switching applications. The cadmium-free composition of the substitute provides environmental compliance advantages.

Q: Is the CB1AH-M-12V suitable for high-temperature automotive applications?

A: The CB1AH-M-12V operates to 85°C maximum ambient temperature. Applications requiring sustained operation above 85°C must use the original VF7-41F11 or identify alternative relays rated to 125°C.

Q: What regulatory advantages does the CB1AH-M-12V provide?

A: The CB1AH-M-12V holds RoHS3 compliance certification and active product status, ensuring regulatory alignment with current environmental standards and continued manufacturer support. Both relays maintain REACH Unaffected and EAR99 ECCN classifications.
