MK2P-I-DC12 Equivalent & Substitute Parts

Part Overview

The MK2P-I-DC12 is a general purpose relay manufactured by Omron Automation and Safety, featuring a DPDT (2 Form C) contact configuration with 10A switching capacity at 12VDC coil voltage. This relay is designed for socketable mounting with an 8-pin octal termination style and includes a mechanical indicator for operational status.

The MK2P-I-DC12 is classified as obsolete. Identifying equivalent substitute parts is essential for maintaining system functionality, ensuring design continuity, and managing component availability in production environments where this relay is specified.

Key Parameters

Substitute Part Grouping Explanation

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

• Coil voltage: 12VDC (exact match required)
• Contact form: DPDT (2 Form C) (exact match required)
• Contact rating: 10A minimum (exact match required)
• Mounting type: Socketable (exact match required)
• Termination style: Plug In, 8 Pin (Octal) (exact match required)
• Coil type: Non Latching (exact match required)

The substitute parts KRPA-11DG-12 and KRPA-11DN-12, both manufactured by TE Connectivity Potter & Brumfield Relays, satisfy all critical substitution criteria. Both parts are currently in active product status, ensuring long-term availability and supply chain stability compared to the obsolete MK2P-I-DC12.

Parameter Comparison

Engineering Selection Recommendations

Both KRPA-11DG-12 and KRPA-11DN-12 are functionally equivalent substitutes for the obsolete MK2P-I-DC12. The selection between these two active alternatives depends on application-specific requirements:

KRPA-11DG-12 provides a direct functional replacement without additional features. This part maintains compatibility with existing socket-based installations and offers ROHS3 compliance with unlimited moisture sensitivity rating.

KRPA-11DN-12 includes a lighted indicator feature in addition to the core relay functionality. This variant also provides ROHS3 compliance and is suitable for applications requiring visual operational feedback. The lighted indicator distinguishes this part from both the original MK2P-I-DC12 and the KRPA-11DG-12.

Both substitute parts operate across a wider temperature range (-45°C ~ 70°C) compared to the original specification (-10°C ~ 40°C), providing enhanced thermal performance. The switching voltage specification of 240VAC for both substitutes is slightly lower than the original 250VAC maximum, which remains acceptable for standard industrial applications within this voltage class.

Frequently Asked Questions (FAQ)

Q: Can KRPA-11DG-12 and KRPA-11DN-12 be used interchangeably with MK2P-I-DC12?

A: Both KRPA parts meet all critical substitution parameters: 12VDC coil voltage, DPDT contact form, 10A contact rating, socketable mounting, and 8-pin octal termination. The primary difference is that KRPA-11DN-12 includes a lighted indicator feature. Selection depends on whether this additional feature is required or acceptable in your application.

Q: What are the key differences between KRPA-11DG-12 and KRPA-11DN-12?

A: Both parts are electrically and mechanically equivalent. KRPA-11DN-12 includes a lighted indicator for operational status visibility, while KRPA-11DG-12 does not. Both are active products with ROHS3 compliance and identical electrical specifications.

Q: Does the lower switching voltage specification (240VAC vs. 250VAC) of the substitute parts affect compatibility?

A: The substitute parts are rated for 240VAC maximum switching voltage, compared to the original 250VAC specification. This difference is within standard industrial voltage classifications and does not affect compatibility for applications operating at standard utility voltages (120VAC, 240VAC, etc.).

Q: Are the substitute parts available in the same packaging as the original?

A: The substitute parts are supplied in tray packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What is the impact of the lower coil current specification (100 mA vs. 126 mA) in the substitute parts?

A: The lower coil current in the substitute parts (100 mA at 120 Ohms resistance) compared to the original (126 mA at 95 Ohms resistance) indicates improved coil efficiency. This results in reduced power consumption and heat generation, which is beneficial for circuit design and thermal management.

Q: Do the substitute parts have the same mechanical indicator feature as the original?

A: KRPA-11DG-12 does not include a mechanical indicator. KRPA-11DN-12 includes a lighted indicator instead. If a mechanical indicator is required, neither substitute provides an exact feature match, though both provide functional relay operation.
