Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MK2P-S-DC12 are qualified based on the following critical parameters that must match or exceed the original specification:

• Coil voltage: 12VDC
• Contact configuration: DPDT (2 Form C)
• Contact current rating: 10A minimum
• Mounting type: Socketable
• Termination: 8 Pin Octal plug-in
• Coil type: Non Latching

The substitute parts identified are grouped into two categories:

Direct Manufacturer Substitute: MKS2PIDC12 from Omron Automation and Safety represents a direct evolution within the same manufacturer's product line, maintaining identical electrical and mechanical specifications while offering active product status.

Similar Manufacturer Substitutes: KRPA-11DG-12 and KRPA-11DN-12 from TE Connectivity Potter & Brumfield Relays meet all critical electrical and mechanical parameters, providing cross-manufacturer compatibility for applications requiring DPDT 12VDC relay functionality.

Parameter Comparison

Engineering Selection Recommendations

MKS2PIDC12 is the primary substitute for the obsolete MK2P-S-DC12. As an active product from the same manufacturer, it maintains identical coil voltage, contact configuration, and current rating specifications. The MKS2PIDC12 offers an extended operating temperature range (-40°C to 60°C versus -10°C to 40°C) and is ROHS3 compliant, making it suitable for modern applications requiring environmental compliance. The lower coil current (112 mA versus 126 mA) reduces power consumption while maintaining functional equivalence.

KRPA-11DG-12 and KRPA-11DN-12 from TE Connectivity Potter & Brumfield Relays provide cross-manufacturer alternatives meeting all critical electrical and mechanical parameters. Both parts are active products with ROHS3 compliance. The KRPA series offers an extended operating temperature range (-45°C to 70°C) and lower coil current (100 mA), providing advantages in temperature-sensitive or power-constrained applications. The KRPA-11DN-12 includes a lighted indicator feature, distinguishing it from the KRPA-11DG-12 which has no indicator features.

Selection between these substitutes should be based on application-specific requirements including operating temperature range, coil current constraints, and feature requirements.

Frequently Asked Questions (FAQ)

Q: Can MKS2PIDC12 be used as a direct replacement for MK2P-S-DC12?

A: Yes. MKS2PIDC12 meets all critical electrical and mechanical specifications: 12VDC coil, DPDT contact configuration, 10A contact rating, socketable mounting, and 8-pin octal termination. The lower coil current and extended temperature range represent improvements over the original specification.

Q: What are the key differences between the Omron MKS2PIDC12 and TE Connectivity KRPA series substitutes?

A: All three substitute parts meet the core functional requirements. Primary differences include coil current (Omron MKS2PIDC12 at 112 mA versus TE Connectivity KRPA series at 100 mA), switching voltage ratings (Omron at 250VAC/30VDC maximum versus TE Connectivity at 240VAC maximum), and contact material composition (Omron uses AgSnIn versus TE Connectivity uses AgCdO). Operating temperature ranges also differ, with TE Connectivity offering -45°C to 70°C versus Omron's -40°C to 60°C.

Q: Are all substitute parts socketable with 8-pin octal termination?

A: Yes. All identified substitutes maintain socketable mounting with 8-pin octal plug-in termination, ensuring mechanical compatibility with existing relay sockets designed for the MK2P-S-DC12.

Q: What is the significance of the different contact materials used in these relays?

A: Contact material composition affects switching characteristics, contact resistance, and longevity under specific load conditions. The MK2P-S-DC12 uses silver (Ag), MKS2PIDC12 uses silver tin indium (AgSnIn), and KRPA series uses silver cadmium oxide (AgCdO). All materials are suitable for general purpose switching applications at the specified 10A rating and voltage levels.

Q: Do all substitute parts meet modern compliance standards?

A: MKS2PIDC12 and both KRPA series parts are ROHS3 compliant. The original MK2P-S-DC12 compliance status is not specified. All parts carry EAR99 ECCN classification and are REACH unaffected or vendor undefined, suitable for standard industrial applications.

Q: What is the impact of different coil currents on circuit design?

A: The MK2P-S-DC12 requires 126 mA coil current, while MKS2PIDC12 requires 112 mA and KRPA series requires 100 mA. Lower coil current reduces power consumption and heat generation. Existing circuits designed for the original 126 mA specification will operate correctly with lower-current substitutes, but new designs may benefit from the reduced power requirements of the KRPA series.
