MK2KP AC24 Equivalent & Substitute Parts

Part Overview

The MK2KP AC24 is a general purpose relay manufactured by Omron Automation and Safety, featuring a DPDT (2 Form C) contact configuration with a 24VAC coil. This socketable relay is designed for applications requiring 5A switching capacity at up to 250VAC or 250VDC. The part is currently active in production with 914 units in stock. Alternative models become necessary when addressing specific inventory constraints, regional availability requirements, or when integrating into systems with existing substitute part qualifications.

Key Parameters

Substitute Part Grouping Explanation

The MK2KP AC24 has one parametric equivalent within the MKK series: MK2KP-UA-AC24. This substitute relationship is established based on strict electrical and mechanical parameter matching across all critical specifications. The substitution criteria include:

• Identical coil voltage (24VAC)
• Identical contact form (DPDT / 2 Form C)
• Identical contact rating (5 A)
• Identical switching voltage capability (250VAC, 250VDC - Max)
• Identical coil current (66 mA)
• Identical coil type (Latching, Dual Coil)
• Identical termination style (Plug In, 11 Pin Octal)
• Identical operating temperature range (-10°C ~ 40°C)
• Identical contact material (Silver)
• Identical coil resistance (105 Ohms)
• Identical RoHS compliance status
• Identical MSL rating (1 - Unlimited)

Both parts share the same base product number (MK2KP) and series designation (MKK), confirming their functional and mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both MK2KP AC24 and MK2KP-UA-AC24 are active production parts with full RoHS compliance and identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and supply chain requirements. The MK2KP-UA-AC24 variant currently maintains higher stock levels (1032 units versus 914 units), making it suitable for high-volume procurement scenarios. Both parts carry identical ECCN (EAR99) and HTSUS classifications, ensuring equivalent regulatory and trade compliance. The MSL rating of 1 (Unlimited) for both parts indicates no moisture sensitivity restrictions during storage or handling.

Frequently Asked Questions (FAQ)

Q: Are MK2KP AC24 and MK2KP-UA-AC24 directly interchangeable?

A: Yes. Both parts are parametrically identical across all electrical and mechanical specifications, including coil voltage, contact configuration, current rating, switching voltage, termination style, and operating temperature range. They share the same base product number and series designation.

Q: What does the "-UA" designation in MK2KP-UA-AC24 indicate?

A: The "-UA" suffix represents a variant designation within the MKK series. This designation does not alter the electrical or mechanical performance characteristics; it reflects a specific product configuration or manufacturing variant that maintains full compatibility with the base MK2KP AC24 specification.

Q: Can I use these relays in applications requiring operation below -10°C or above 40°C?

A: No. Both parts are specified for operation within -10°C to 40°C. Applications outside this range require evaluation of alternative relay models with extended temperature ratings.

Q: Are there any differences in RoHS or regulatory compliance between these parts?

A: No. Both parts are RoHS Compliant with identical ECCN (EAR99) and HTSUS (8536.41.0020) classifications. They carry equivalent regulatory status for all markets.

Q: What is the significance of the 11 Pin Octal termination style?

A: The 11 Pin Octal termination indicates a socketable plug-in configuration. This allows the relay to be inserted into a standard 11-pin octal socket base, enabling tool-free installation and removal. Both substitute parts maintain this identical termination specification.

Q: Should I consider inventory levels when selecting between these parts?

A: Inventory levels may influence procurement decisions for high-volume applications. MK2KP-UA-AC24 currently maintains 1032 units in stock compared to 914 units for MK2KP AC24. For single-unit or low-volume requirements, both parts are equally suitable based on availability.
