Omron MK2P-I-AC12 General Purpose Relay - Equivalent & Substitute Parts

Part Overview

The Omron MK2P-I-AC12 is a general purpose relay with DPDT (2 Form C) contact configuration, rated for 10A at 12VAC coil voltage. This socketable, 8-pin octal relay features a mechanical indicator and is designed for standard switching applications in industrial control systems. The product is classified as obsolete, making equivalent substitute parts necessary for system maintenance, repair, and replacement applications where original stock is unavailable.

Key Parameters

Substitute Part Grouping Explanation

The TE Connectivity Potter & Brumfield KRPA-11AG-12 relay qualifies as a functional substitute for the Omron MK2P-I-AC12 based on the following critical parameters:

• Coil Voltage: Both relays operate at 12VAC
• Contact Configuration: Both feature DPDT (2 Form C) contact form
• Current Rating: Both are rated for 10A switching capacity
• Mounting Architecture: Both are socketable with 8-pin octal termination
• Coil Type: Both are non-latching relays
• Relay Classification: Both are general purpose relays

These parameters define the functional interchangeability for direct replacement in applications requiring identical electrical and mechanical interfaces.

Parameter Comparison

Engineering Selection Recommendations

Both the Omron MK2P-I-AC12 and TE Connectivity KRPA-11AG-12 are classified as obsolete products. Selection between these relays should be based on application-specific requirements and availability:

The KRPA-11AG-12 offers an extended operating temperature range (-45°C to 55°C) compared to the MK2P-I-AC12 (-10°C to 40°C), making it suitable for applications requiring broader thermal performance. The KRPA-11AG-12 also carries RoHS3 compliance certification, which may be required for certain regulatory environments.

The MK2P-I-AC12 provides higher maximum switching voltage capability (250VAC/250VDC versus 240VAC for the KRPA-11AG-12), which may be relevant for high-voltage switching applications.

Both relays share identical core electrical and mechanical specifications (12VAC coil, DPDT configuration, 10A rating, 8-pin octal socketable mounting), ensuring functional compatibility in standard replacement scenarios.

Frequently Asked Questions (FAQ)

Q: Can the KRPA-11AG-12 directly replace the MK2P-I-AC12 in existing applications?

A: Yes. Both relays share identical coil voltage (12VAC), contact configuration (DPDT), current rating (10A), and socketable 8-pin octal termination. Direct socket replacement is mechanically and electrically compatible.

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

A: The primary differences are: (1) Operating temperature range—KRPA-11AG-12 operates from -45°C to 55°C versus MK2P-I-AC12 at -10°C to 40°C; (2) Maximum switching voltage—MK2P-I-AC12 supports 250VAC/250VDC versus KRPA-11AG-12 at 240VAC; (3) Contact material—MK2P-I-AC12 uses silver (Ag) while KRPA-11AG-12 uses silver cadmium oxide (AgCdO); (4) Coil resistance—MK2P-I-AC12 is 16.3 Ohms versus KRPA-11AG-12 at 24 Ohms; (5) RoHS compliance—KRPA-11AG-12 is RoHS3 compliant.

Q: Are there any voltage compatibility concerns?

A: The must-operate voltage differs slightly: MK2P-I-AC12 requires 9.6VAC minimum while KRPA-11AG-12 requires 10.2VAC minimum. In applications with marginal supply voltage, verify that the 12VAC source reliably exceeds 10.2VAC to ensure KRPA-11AG-12 operation.

Q: Which relay should I select for temperature-critical applications?

A: The KRPA-11AG-12 is suitable for applications requiring operation below -10°C or above 40°C, as it supports -45°C to 55°C. The MK2P-I-AC12 is limited to -10°C to 40°C.

Q: Are both relays available in current inventory?

A: Both relays are classified as obsolete products. Availability should be confirmed with component suppliers before design finalization.
