Key Parameters

Substitute Part Grouping Explanation

The KUP-14A15-120 manufactured by TE Connectivity Potter & Brumfield Relays qualifies as a direct substitute based on the following critical parameters:

• Coil voltage: 120VAC (identical)
• Contact form: 3PDT (3 Form C) (identical)
• Contact rating: 10 A (identical)
• Mounting type: Socketable (identical)
• Termination style: Plug In, Quick Connect - 0.187" (4.7mm) (identical)
• Coil type: Non Latching (identical)
• Operating temperature range: -45°C ~ 45°C (identical)
• Coil resistance: 1.7 kOhms (identical)
• Must operate voltage: 102 VAC (identical)

These parameters establish functional and mechanical compatibility for direct substitution in applications requiring 120VAC 3PDT general purpose relays with socketable configuration.

Parameter Comparison

Engineering Selection Recommendations

Both the MJN3C-AC120 and KUP-14A15-120 are active products suitable for 120VAC 3PDT relay applications. The MJN3C-AC120 is RoHS compliant, making it the preferred choice for applications subject to RoHS regulations or customer requirements. The KUP-14A15-120 is RoHS non-compliant and REACH affected, requiring evaluation against specific application compliance mandates. The KUP-14A15-120 exhibits faster operate time (15 ms versus 20 ms) and higher coil current draw (24 mA versus 16.7 mA), with lower maximum switching voltage (240VAC versus 600VAC, 28VDC). Selection between these parts should be based on regulatory compliance requirements and application-specific voltage and timing constraints.

Frequently Asked Questions (FAQ)

Q: Can the KUP-14A15-120 be used as a direct replacement for the MJN3C-AC120?

A: The KUP-14A15-120 is mechanically and functionally compatible for applications requiring 120VAC 3PDT socketable relays with 10A contact rating. However, compliance requirements must be evaluated. The MJN3C-AC120 is RoHS compliant while the KUP-14A15-120 is not, and the KUP-14A15-120 is REACH affected. Application-specific voltage and timing requirements must also be confirmed.

Q: What are the key differences between these two relays?

A: The primary differences are RoHS compliance status, maximum switching voltage (MJN3C-AC120 supports 600VAC/28VDC versus KUP-14A15-120 at 240VAC), coil current (16.7 mA versus 24 mA), operate time (20 ms versus 15 ms), and contact material (Silver Alloy versus Silver Cadmium Oxide).

Q: Are the socketable mounting and termination styles identical?

A: Yes. Both relays feature socketable mounting and identical Plug In, Quick Connect termination at 0.187" (4.7mm), ensuring mechanical compatibility in socket-based applications.

Q: What is the operating temperature range for both relays?

A: Both the MJN3C-AC120 and KUP-14A15-120 operate across the same temperature range of -45°C to 45°C.

Q: Do both relays have the same coil resistance?

A: Yes. Both relays have a coil resistance of 1.7 kOhms and a must operate voltage of 102 VAC.
