Omron MK2P-I-DC24 Equivalent & Substitute Parts

Part Overview

The Omron MK2P-I-DC24 is a general purpose relay with DPDT (2 Form C) contact configuration, rated for 10A at 24VDC coil voltage. This socketable, 8-pin octal relay features a mechanical indicator and is designed for non-latching operation in industrial control applications. The MK2P-I-DC24 is classified as obsolete, making identification of equivalent substitute parts essential for system maintenance, repair, and new design implementations where this relay type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MK2P-I-DC24 are qualified based on the following critical parameters that determine functional equivalence:

• Coil voltage: 24VDC
• Contact form: DPDT (2 Form C)
• Contact rating: 10A minimum
• Termination style: Plug In, 8 Pin (Octal)
• Mounting type: Socketable
• Coil type: Non Latching

The TE Connectivity Potter & Brumfield KRPA-11DG-24 and KRPA-11DN-24 relays satisfy all mandatory substitution criteria. Both parts maintain identical coil voltage, contact configuration, current rating, and octal socketable termination. The KRPA series relays are active products with current manufacturing status, providing long-term availability compared to the obsolete MK2P-I-DC24.

Parameter Comparison

Engineering Selection Recommendations

Both KRPA-11DG-24 and KRPA-11DN-24 relays are qualified substitutes for the obsolete MK2P-I-DC24. Selection between the two KRPA variants depends on application requirements:

The KRPA-11DG-24 provides a direct functional replacement without additional features, maintaining the core relay functionality of the original MK2P-I-DC24.

The KRPA-11DN-24 includes a lighted indicator feature, offering enhanced operational visibility compared to the mechanical indicator of the original part.

Both KRPA relays are active products with RoHS3 compliance status, ensuring continued availability and regulatory alignment. The KRPA series operates across an extended temperature range (-45°C to 70°C) compared to the MK2P-I-DC24 (-10°C to 40°C), providing broader environmental suitability. Coil current consumption is slightly lower in the KRPA variants (51 mA versus 56 mA), resulting in reduced power draw during operation.

Frequently Asked Questions (FAQ)

Q: Can KRPA-11DG-24 and KRPA-11DN-24 be used interchangeably with MK2P-I-DC24?

A: Both KRPA relays meet the core electrical and mechanical requirements for substitution: identical 24VDC coil voltage, DPDT contact configuration, 10A current rating, and 8-pin octal socketable termination. Direct socket compatibility is maintained.

Q: What is the difference between KRPA-11DG-24 and KRPA-11DN-24?

A: The primary difference is the indicator feature. KRPA-11DG-24 has no indicator, while KRPA-11DN-24 includes a lighted indicator for operational status visibility. All other electrical and mechanical parameters are identical.

Q: Are there any switching voltage differences I should consider?

A: The MK2P-I-DC24 is rated for 250VAC/250VDC maximum switching voltage, while both KRPA variants are rated for 240VAC maximum. For applications operating at or near 250VAC, the original MK2P-I-DC24 specification should be verified against actual system requirements.

Q: What is the impact of different contact materials?

A: The MK2P-I-DC24 uses silver (Ag) contacts, while KRPA relays use silver cadmium oxide (AgCdO) contacts. Both materials are suitable for general purpose relay applications. Contact material selection depends on specific load characteristics and application environment.

Q: Are the KRPA relays RoHS compliant?

A: Yes, both KRPA-11DG-24 and KRPA-11DN-24 are RoHS3 compliant, meeting current environmental and regulatory requirements.

Q: What is the operating temperature range difference?

A: The MK2P-I-DC24 operates from -10°C to 40°C, while KRPA relays operate from -45°C to 70°C. The extended KRPA temperature range provides greater flexibility for applications in extreme environments.
