Equivalent & Substitute Parts for MK3ZP-DC24

Part Overview

The MK3ZP-DC24 is a general purpose relay manufactured by Omron Automation and Safety, featuring a 3PDT (3 Form C) contact configuration with a 24VDC coil. This socketable relay is designed for applications requiring switching of 10A loads at up to 250VAC or 250VDC. The part is currently active in production with 1126 units in stock. Alternative models become necessary when specific inventory constraints exist, when packaging requirements differ, or when extended operating temperature ranges are required for particular applications.

Key Parameters

Parameter	Value

Contact Form	3PDT (3 Form C)
Contact Rating (Current)	10 A
Switching Voltage	250VAC, 250VDC - Max
Mounting Type	Socketable
Termination Style	Plug In, 11 Pin (Octal)
Coil Type	Non Latching
Contact Material	Silver (Ag)
Operating Temperature	-10°C ~ 40°C
RoHS Status	RoHS Compliant

Substitute Part Grouping Explanation

Substitution eligibility for the MK3ZP-DC24 is determined by strict alignment with the following critical parameters:

Coil voltage must be 24VDC
Contact configuration must be 3PDT (3 Form C)
Current rating must be 10A
Mounting type must be socketable
Termination must be 11 Pin Octal plug-in style
Coil type must be non-latching

The substitute parts identified—MK3P-13-DC24, KRPA-14DG-24, and KRPA-14DN-24—meet all mandatory electrical and mechanical parameters. Variations in secondary parameters such as coil current, switching voltage maximum ratings, operating temperature range, contact material composition, and coil resistance do not preclude substitution when the primary parameters align.

Engineering Selection Recommendations

MK3P-13-DC24 is a parametric equivalent manufactured by Omron. This part shares identical electrical specifications with the MK3ZP-DC24, including coil voltage, contact configuration, current rating, switching voltage, coil current, and operating temperature range. Both parts are RoHS Compliant and carry the same ECCN and HTSUS classifications. Selection of this part is appropriate when Omron product continuity is required or when inventory of the primary part is constrained.

KRPA-14DG-24 and KRPA-14DN-24 are manufactured by TE Connectivity Potter & Brumfield Relays and meet all mandatory substitution criteria. These parts carry ROHS3 Compliant certification and support an extended operating temperature range of -45°C to 70°C compared to the -10°C to 40°C range of the MK3ZP-DC24. The KRPA-14DN-24 includes a lighted indicator feature not present in the primary part. Selection of TE Connectivity alternatives is appropriate when extended temperature performance is required, when higher inventory availability is needed, or when tray packaging is preferred over bulk packaging.

Frequently Asked Questions (FAQ)

Q: Can MK3P-13-DC24 be used as a direct replacement for MK3ZP-DC24?

A: Yes. The MK3P-13-DC24 is a parametric equivalent with identical coil voltage, contact configuration, current rating, switching voltage, coil current, and operating temperature specifications. Both parts use 11 Pin Octal socketable termination and are RoHS Compliant.

Q: What are the differences between Omron and TE Connectivity substitute options?

A: The Omron MK3P-13-DC24 maintains identical specifications to the MK3ZP-DC24. The TE Connectivity KRPA-14DG-24 and KRPA-14DN-24 provide extended operating temperature range (-45°C to 70°C versus -10°C to 40°C), lower coil current (51 mA versus 56 mA), and different contact material composition (Silver Cadmium Oxide versus Silver). The KRPA-14DN-24 includes a lighted indicator feature.

Q: Are there packaging differences between these parts?

A: Yes. The MK3ZP-DC24 and MK3P-13-DC24 are supplied in bulk packaging. The KRPA-14DG-24 and KRPA-14DN-24 are supplied in tray packaging. All parts use identical 11 Pin Octal socketable termination.

Q: Do all substitute parts meet the same compliance standards?

A: The MK3ZP-DC24 and MK3P-13-DC24 are RoHS Compliant. The KRPA-14DG-24 and KRPA-14DN-24 are ROHS3 Compliant. All parts share the same ECCN (EAR99) and HTSUS (8536.41.0050) classifications.

Q: Which substitute part has the highest inventory availability?

A: The KRPA-14DN-24 has 2300 units in stock, compared to 1126 units for the MK3ZP-DC24, 700 units for the MK3P-13-DC24, and 866 units for the KRPA-14DG-24.
