VF4-15H13 Equivalent & Substitute Parts

Part Overview

The VF4-15H13 is a general purpose relay manufactured by TE Connectivity Potter & Brumfield Relays. This through-hole mounted device features a 24VDC coil, SPDT (1 Form C) contact configuration, and a 40A contact rating. The relay operates with a 7 ms response time and is designed for applications requiring reliable switching at moderate to high current levels. The part is currently active in production with 840 units in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters allow direct replacement in the same application circuit without modification to the host system design.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VF4-15H13 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Coil voltage: 24VDC
• Contact form: SPDT (1 Form C)
• Mounting type: Through hole
• Termination style: PC Pin
• Coil type: Non latching
• Must operate voltage: 14.4 VDC or lower
• Must release voltage: 2.4 VDC or lower

Allowable Variation Parameters:

• Contact rating (current): Equal to or greater than 40A
• Operating temperature range: Must encompass the application's required range
• Operate and release times: May vary within application tolerance
• Coil current and resistance: May vary
• Contact material composition: May vary
• Regulatory compliance: Must maintain RoHS compliance

The CB1-P-24V from Panasonic Electric Works meets the mandatory matching parameters for coil voltage, contact form, mounting type, termination style, and coil type. However, the contact rating of 20A is below the 40A requirement of the VF4-15H13, limiting its substitution applicability to circuits requiring 20A or less.

Parameter Comparison

Engineering Selection Recommendations

The CB1-P-24V is listed as a substitute part for the VF4-15H13 based on matching coil voltage, contact form, mounting configuration, and termination style. Both relays are active products with RoHS compliance and unlimited moisture sensitivity ratings.

Application Scope Limitation: The CB1-P-24V contact rating of 20A restricts its use to circuits where the maximum switching current does not exceed 20A. Applications requiring the full 40A switching capacity of the VF4-15H13 cannot use the CB1-P-24V as a direct substitute.

Temperature Consideration: The CB1-P-24V operating temperature range extends to 85°C maximum, compared to 125°C for the VF4-15H13. Applications operating above 85°C require the VF4-15H13.

Response Time Difference: The CB1-P-24V exhibits longer operate and release times (15 ms each) compared to the VF4-15H13 (7 ms operate, 2 ms release). Applications with timing-critical switching requirements may be affected by this difference.

Regulatory Compliance: Both parts maintain current RoHS compliance status and carry the same ECCN and HTSUS classifications, supporting equivalent supply chain and regulatory treatment.

Frequently Asked Questions (FAQ)

Q: Can the CB1-P-24V replace the VF4-15H13 in all applications?

A: No. The CB1-P-24V is suitable only for applications where the switching current requirement does not exceed 20A. The VF4-15H13 is rated for 40A switching current. If your application requires switching currents between 20A and 40A, the CB1-P-24V cannot be used.

Q: What is the impact of the different operate and release times?

A: The CB1-P-24V has operate and release times of 15 ms each, while the VF4-15H13 operates in 7 ms and releases in 2 ms. In applications where relay response speed is critical to system performance, this difference must be evaluated against circuit timing requirements.

Q: Are both relays RoHS compliant?

A: Yes. The VF4-15H13 is RoHS Compliant, and the CB1-P-24V is ROHS3 Compliant. Both meet current RoHS requirements and are suitable for applications with RoHS compliance mandates.

Q: Do both relays use the same mounting and termination?

A: Yes. Both the VF4-15H13 and CB1-P-24V are through-hole mounted devices with PC pin termination, allowing physical interchangeability on the same PCB layout.

Q: What is the temperature operating range difference?

A: The VF4-15H13 operates from -40°C to 125°C, while the CB1-P-24V operates from -40°C to 85°C. If your application requires operation above 85°C, the VF4-15H13 is required.

Q: Are the coil voltages identical?

A: Yes. Both relays operate on 24VDC coil voltage. The must-operate and must-release voltage thresholds are also compatible, with the CB1-P-24V requiring 14VDC to operate (compared to 14.4VDC for the VF4-15H13).

Q: What is the difference in contact material?

A: The VF4-15H13 uses Silver Nickel (AgNi) contacts, while the CB1-P-24V uses Silver Alloy with cadmium-free composition. Both materials are suitable for general-purpose switching applications, though contact material selection may affect performance in specific chemical or corrosive environments.
