JC2AF-S-DC48V Equivalent & Substitute Parts

Part Overview

The JC2AF-S-DC48V is a general purpose relay manufactured by Panasonic Electric Works, configured as a DPST-NO (2 Form A) with a 48VDC coil and 10A contact rating. This socketable relay is designed for general switching applications requiring dual pole, single throw functionality at 48 volts DC.

The JC2AF-S-DC48V is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for replacement, repair, and new design implementations where this relay specification remains applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the JC2AF-S-DC48V is determined by strict equivalence across the following critical parameters:

• Coil Voltage: 48VDC (exact match required)
• Contact Form: DPST-NO (2 Form A) (exact match required)
• Contact Rating: 10A minimum (exact match required)
• Mounting Type: Socketable (exact match required)
• Termination Style: Plug In, Quick Connect - 0.187" (4.7mm) (exact match required)
• Coil Type: Non Latching (exact match required)

The KUEP-7D15-48 manufactured by TE Connectivity Potter & Brumfield Relays meets all critical substitution criteria. Both relays share identical coil voltage, contact configuration, current rating, socketable mounting, and termination interface. These parameters ensure mechanical and electrical compatibility within the same application circuit.

Parameter Comparison

Engineering Selection Recommendations

The KUEP-7D15-48 is the qualified substitute for the JC2AF-S-DC48V based on product status and compliance factors:

Product Status: The JC2AF-S-DC48V is obsolete, while the KUEP-7D15-48 is active. Active product status ensures ongoing availability, manufacturing support, and supply chain continuity.

Compliance: The KUEP-7D15-48 is RoHS3 compliant, meeting current environmental and regulatory standards. The JC2AF-S-DC48V compliance status is not specified in available documentation.

Electrical Compatibility: Both relays operate at 48VDC with identical contact configuration (DPST-NO), current rating (10A), and termination interface. The KUEP-7D15-48 demonstrates a lower must-operate voltage (36 VDC vs. 38.4 VDC), providing improved operational margin in low-voltage scenarios.

Mechanical Compatibility: Socketable mounting and 0.187" (4.7mm) quick-connect termination are identical, ensuring direct physical replacement without socket or connector modification.

Frequently Asked Questions (FAQ)

Q: Can the KUEP-7D15-48 directly replace the JC2AF-S-DC48V in existing applications?

A: Yes. Both relays share identical coil voltage (48VDC), contact configuration (DPST-NO), current rating (10A), socketable mounting, and termination interface (0.187" quick-connect). Direct socket replacement is possible without circuit or mechanical modification.

Q: What are the differences in coil current between these relays?

A: The JC2AF-S-DC48V draws 20.8 mA, while the KUEP-7D15-48 draws 38 mA. The higher coil current of the substitute requires verification that the control circuit can supply this additional current without exceeding driver or power supply ratings.

Q: How do the switching voltage ratings differ?

A: The JC2AF-S-DC48V is rated for 250VAC maximum switching voltage. The KUEP-7D15-48 is rated for 150VDC maximum switching voltage. Application circuits must operate within the lower switching voltage specification of the substitute.

Q: Are there temperature range differences?

A: The JC2AF-S-DC48V operates from -50°C to 60°C. The KUEP-7D15-48 operates from -45°C to 70°C. The substitute provides a wider upper temperature range but a narrower lower temperature range. Applications requiring operation below -45°C are not suitable for the KUEP-7D15-48.

Q: What is the difference in release time?

A: The JC2AF-S-DC48V releases in 2 ms, while the KUEP-7D15-48 releases in 10 ms. Applications requiring fast de-energization must account for the longer release time of the substitute.

Q: Are the contact materials compatible with the same load types?

A: The JC2AF-S-DC48V uses silver alloy contacts, while the KUEP-7D15-48 uses silver cadmium oxide (AgCdO) contacts. Both materials are suitable for general purpose switching. Application-specific load characteristics (resistive, inductive, capacitive) must be evaluated against the contact material specifications provided by each manufacturer.
