Substitute Part Grouping Explanation

Substitution eligibility for the MJN2C-DC24 is determined by the following critical parameters:

• Coil Voltage: Must be 24VDC to ensure direct compatibility with existing control circuits
• Contact Form: Must be DPDT (2 Form C) to maintain identical switching functionality
• Contact Rating: Must be rated for minimum 10A to handle the same load requirements
• Mounting Type: Must be socketable to fit existing relay sockets
• Termination Style: Must use Plug In, Quick Connect - 0.187" (4.7mm) connectors for mechanical compatibility
• Coil Type: Must be Non Latching for identical operational behavior
• Operating Temperature Range: Must support -45°C ~ 70°C minimum
• Must Operate Voltage: Must be 18 VDC or lower to ensure reliable operation at minimum coil voltage

The substitute part KUP-11D15-24 meets all critical substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

MJN2C-DC24 (Omron) is recommended for applications requiring:

• RoHS compliance certification
• Maximum switching voltage capability (600VAC, 28VDC)
• Silver alloy contact material specifications

KUP-11D15-24 (TE Connectivity) is recommended for applications where:

• Faster operate time (15 ms vs 20 ms) is beneficial
• RoHS compliance is not a requirement
• Maximum switching voltage of 240VAC is sufficient
• Silver cadmium oxide contact material is acceptable

Both relays are active products with current manufacturing status and meet all critical functional substitution criteria for 24VDC DPDT socketable relay applications.

Frequently Asked Questions (FAQ)

Q: Can KUP-11D15-24 be used as a direct replacement for MJN2C-DC24 in existing circuits?

A: Yes, for applications where the maximum switching voltage of 240VAC is sufficient and RoHS compliance is not required. Both relays share identical coil voltage, contact form, current rating, mounting type, and termination style. The KUP operates 5 ms faster, which may be advantageous in time-sensitive applications.

Q: What is the difference in contact material between these relays?

A: The MJN2C-DC24 uses silver alloy contacts, while the KUP-11D15-24 uses silver cadmium oxide (AgCdO) contacts. Silver cadmium oxide provides enhanced arc resistance and contact life in certain switching applications, while silver alloy offers different electrical characteristics. Selection depends on specific load switching requirements.

Q: Are there RoHS compliance differences between these parts?

A: Yes. The MJN2C-DC24 is RoHS compliant, while the KUP-11D15-24 is RoHS non-compliant and REACH affected. Applications subject to RoHS regulations must use the MJN2C-DC24.

Q: Do both relays fit the same socket?

A: Yes. Both relays are socketable with identical Plug In, Quick Connect - 0.187" (4.7mm) termination, ensuring mechanical compatibility with the same relay socket bases.

Q: What is the significance of the 5 ms difference in operate time?

A: The KUP-11D15-24 operates in 15 ms compared to the MJN2C-DC24 at 20 ms. This 5 ms faster response may be critical in applications requiring rapid switching response, such as protective circuits or high-speed control systems. Both have identical 10 ms release time.

Q: Can these relays be used interchangeably in high-voltage AC applications?

A: No. The MJN2C-DC24 is rated for 600VAC maximum switching voltage, while the KUP-11D15-24 is rated for 240VAC maximum. For applications exceeding 240VAC, only the MJN2C-DC24 is suitable.
