Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MJN2C-DC12 is determined by strict alignment of the following critical parameters:

• Coil voltage: 12VDC
• Contact configuration: DPDT (2 Form C)
• Contact current rating: 10 A minimum
• Mounting type: Socketable
• Termination style: Plug In, Quick Connect - 0.187" (4.7mm)
• Coil current: 100 mA
• Coil resistance: 120 Ohms
• Must operate voltage: 9 VDC minimum
• Operating temperature range: -45°C ~ 70°C or wider

The KUP-11D15-12 meets all substitution criteria. Variations in switching voltage ratings, contact material composition, operate time, and compliance certifications do not preclude functional substitution when the above parameters are satisfied.

Parameter Comparison

Engineering Selection Recommendations

Both the MJN2C-DC12 and KUP-11D15-12 are active production relays suitable for general purpose switching applications with identical coil voltage, contact configuration, current rating, and mechanical interface specifications.

The MJN2C-DC12 is RoHS compliant and supports higher maximum switching voltage (600VAC, 28VDC) compared to the KUP-11D15-12 (240VAC maximum). The MJN2C-DC12 also features a longer operate time of 20 ms versus 15 ms for the KUP-11D15-12.

The KUP-11D15-12 is RoHS non-compliant and REACH affected. Selection between these parts should be based on regulatory compliance requirements, maximum switching voltage requirements for the target application, and response time specifications.

Frequently Asked Questions (FAQ)

Q: Can the KUP-11D15-12 directly replace the MJN2C-DC12 in existing designs?

A: Yes, provided the application does not exceed 240VAC maximum switching voltage and the 15 ms operate time of the KUP-11D15-12 is acceptable. Both relays share identical coil voltage, contact configuration, current rating, mounting type, and termination style.

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

A: The primary differences are maximum switching voltage rating (MJN2C-DC12: 600VAC/28VDC; KUP-11D15-12: 240VAC), operate time (MJN2C-DC12: 20 ms; KUP-11D15-12: 15 ms), contact material composition, and RoHS compliance status (MJN2C-DC12 compliant; KUP-11D15-12 non-compliant).

Q: Are the physical packages identical?

A: Yes. Both relays use socketable mounting with Plug In, Quick Connect termination at 0.187" (4.7mm) spacing, ensuring mechanical compatibility in relay socket applications.

Q: Which relay should I select for RoHS-compliant applications?

A: The MJN2C-DC12 is RoHS compliant. The KUP-11D15-12 is RoHS non-compliant and REACH affected, making it unsuitable for applications with RoHS compliance requirements.

Q: Do these relays have identical electrical performance?

A: Both relays operate at 12VDC with 100 mA coil current, 120 Ohms coil resistance, and 9 VDC minimum operate voltage. The KUP-11D15-12 has a faster operate time (15 ms vs. 20 ms). The MJN2C-DC12 supports higher switching voltage levels.
