Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VF4A-15F11-S01 is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

• Coil voltage: 12VDC
• Contact form: SPDT (1 Form C)
• Contact rating: 40A minimum
• Mounting type: Socketable
• Termination style: Plug In, Quick Connect - 0.250" (6.3mm)
• Coil type: Non-latching
• Features: Integrated resistor

Secondary Compatibility Parameters:

• Operating temperature range (minimum -40°C, maximum 125°C or higher)
• Must operate voltage: 7.0 VDC or lower
• Must release voltage: 1.2 VDC or higher
• Switching voltage: 14VDC nominal

The substitute parts are grouped into two categories:

Direct Equivalents (Identical Electrical and Mechanical Specifications):

• 1-1414687-0 (TE Connectivity Potter & Brumfield Relays, SRF-A series): Matches all primary and secondary parameters with active product status and RoHS3 compliance.

Compatible Alternatives (Functionally Equivalent with Minor Parameter Variations):

• CB1-T-R-12V, CB1F-T-R-12V, CB1-R-12V, CB1F-R-12V (Panasonic Electric Works, CB series): Meet all primary equivalence criteria. Operating temperature upper limit of 85°C represents a constraint for applications requiring full -40°C to 125°C range. Coil current is 134 mA versus 151 mA in the original part. Contact material is silver alloy cadmium-free versus silver nickel. All feature sealed construction and active product status.

Engineering Selection Recommendations

1-1414687-0 (TE Connectivity Potter & Brumfield Relays, SRF-A Series)

This part is the primary substitute for the VF4A-15F11-S01. It maintains identical electrical specifications including coil voltage, contact rating, switching voltage, operate time, release time, and coil resistance. The part is manufactured by the same original equipment manufacturer, ensuring design continuity. Product status is active with RoHS3 compliance and MSL rating of 1 (Unlimited), supporting long-term procurement and environmental compliance requirements.

CB1-T-R-12V and CB1F-T-R-12V (Panasonic Electric Works, CB Series)

These parts are compatible alternatives with full operating temperature range support (-40°C to 125°C). Both maintain the required 40A contact rating, 12VDC coil voltage, and socketable mounting with 0.250" quick-connect termination. CB1-T-R-12V features fully sealed construction, while CB1F-T-R-12V includes flux protection sealing. Differences include 134 mA coil current (versus 151 mA), 89.5 Ohm coil resistance (versus 79.5 Ohm), and extended operate/release times of 15 ms each. Contact material is silver alloy cadmium-free. Both are active products with RoHS3 compliance.

CB1-R-12V and CB1F-R-12V (Panasonic Electric Works, CB Series)

These parts are compatible alternatives with operating temperature range limited to -40°C to 85°C. Selection of these parts is appropriate only for applications not requiring operation above 85°C. CB1-R-12V features fully sealed construction, while CB1F-R-12V includes flux protection sealing. Electrical specifications match CB1-T-R-12V and CB1F-T-R-12V variants. Both are active products with RoHS3 compliance and REACH Unaffected status.

Selection Criteria Summary:

• For direct replacement with identical timing and temperature range: 1-1414687-0
• For sealed construction with full temperature range: CB1-T-R-12V or CB1F-T-R-12V
• For sealed construction with limited temperature range (≤85°C): CB1-R-12V or CB1F-R-12V
• For flux-protected applications: CB1F-T-R-12V or CB1F-R-12V
• For fully sealed applications: CB1-T-R-12V or CB1-R-12V

Frequently Asked Questions (FAQ)

Q: Can the 1-1414687-0 be used as a direct drop-in replacement for the VF4A-15F11-S01?

A: Yes. The 1-1414687-0 maintains identical coil voltage (12VDC), contact form (SPDT), contact rating (40A), coil resistance (79.5 Ohms), operate time (7 ms), release time (2 ms), and operating temperature range (-40°C to 125°C). Socketable mounting and 0.250" quick-connect termination are identical. The part is manufactured by the same original equipment manufacturer.

Q: What is the primary difference between the Panasonic CB series alternatives and the original VF4A-15F11-S01?

A: The Panasonic CB series relays feature sealed construction (fully sealed or flux-protected) and cadmium-free silver alloy contact material. Coil current is reduced to 134 mA with increased coil resistance to 89.5 Ohms. Operate and release times are extended to 15 ms each. CB1-R-12V and CB1F-R-12V variants have a maximum operating temperature of 85°C, while CB1-T-R-12V and CB1F-T-R-12V support the full -40°C to 125°C range.

Q: Are the Panasonic CB series relays compatible with the same socket as the VF4A-15F11-S01?

A: Yes. All substitute parts maintain socketable mounting type with Plug In, Quick Connect - 0.250" (6.3mm) termination style, ensuring mechanical compatibility with existing relay sockets designed for the VF4A-15F11-S01.

Q: Which substitute part should be selected for applications requiring operation above 85°C?

A: For applications requiring operation in the full -40°C to 125°C temperature range, select either 1-1414687-0, CB1-T-R-12V, or CB1F-T-R-12V. The CB1-R-12V and CB1F-R-12V variants are limited to -40°C to 85°C and are not suitable for high-temperature applications.

Q: What is the significance of the flux protection feature in CB1F-T-R-12V and CB1F-R-12V?

A: Flux protection sealing provides additional protection against flux residue and contaminants during soldering or assembly processes. This feature is beneficial in manufacturing environments where flux exposure is present. Fully sealed variants (CB1-T-R-12V and CB1-R-12V) provide general environmental sealing without specific flux protection designation.

Q: How do the timing characteristics of the substitute parts compare to the original VF4A-15F11-S01?

A: The 1-1414687-0 maintains identical operate time (7 ms) and release time (2 ms). The Panasonic CB series alternatives (CB1-T-R-12V, CB1F-T-R-12V, CB1-R-12V, CB1F-R-12V) have extended timing with 15 ms operate time and 15 ms release time. Applications with strict timing requirements should use the 1-1414687-0 or evaluate whether the extended timing of the CB series is acceptable.

Q: What compliance certifications are relevant for substitute part selection?

A: All substitute parts are RoHS compliant. The 1-1414687-0 is RoHS3 compliant with REACH status vendor-undefined. The Panasonic CB series parts are RoHS3 compliant with REACH Unaffected status (except CB1F-T-R-12V, which does not specify REACH status). For applications requiring specific environmental compliance, verify the applicable regulatory requirements against the provided certification data.

Q: Is the coil current difference between the VF4A-15F11-S01 (151 mA) and the Panasonic CB series (134 mA) significant?

A: The coil current difference reflects the higher coil resistance in the CB series (89.5 Ohms versus 79.5 Ohms). At 12VDC, the CB series draws less current while maintaining the same switching voltage and contact rating. This difference is not significant for most applications and may provide a slight power consumption benefit. Verify that the control circuit can accommodate the different coil resistance if precise current limiting is required.
