Substitute Part Grouping Explanation

Substitution eligibility for the MK3ZP-2-DC24 is determined by the following critical parameters:

Coil Voltage: 24VDC (exact match required)
Contact Form: 3PDT (3 Form C) (exact match required)
Contact Rating: 10 A minimum (exact match required)
Mounting Type: Socketable (exact match required)
Termination Style: Plug In, 11 Pin (Octal) (exact match required)
Coil Type: Non Latching (exact match required)

The substitute parts listed below meet all critical electrical and mechanical parameters. Variations in secondary parameters such as coil current, operating temperature range, contact material composition, and compliance certifications do not prevent functional substitution when the above criteria are satisfied.

Engineering Selection Recommendations

All listed substitute parts are active products with current manufacturing status and meet the critical electrical and mechanical specifications required for direct substitution with the MK3ZP-2-DC24.

MK3P-13-DC24 (Omron Automation and Safety): This part is a parametric equivalent manufactured by the same supplier as the main part. It shares identical coil voltage, contact configuration, current rating, and operating characteristics. Both parts maintain RoHS compliance and are suitable for equivalent performance in existing designs.

KRPA-14DG-24 and KRPA-14DN-24 (TE Connectivity Potter & Brumfield Relays): These parts meet all critical substitution criteria and are manufactured by an alternative qualified supplier. Both maintain ROHS3 compliance. The KRPA-14DN-24 includes a lighted indicator feature not present in the main part. The TE Connectivity relays operate across a wider temperature range (-45°C ~ 70°C) compared to the Omron parts (-10°C ~ 40°C), providing extended environmental capability for applications requiring broader temperature tolerance.

All substitute parts are available in active production with confirmed inventory levels.

Frequently Asked Questions (FAQ)

Q: Can MK3P-13-DC24 be used as a direct replacement for MK3ZP-2-DC24?

A: Yes. Both parts are manufactured by Omron Automation and Safety and share identical electrical specifications including 24VDC coil voltage, 3PDT contact form, 10A contact rating, and 11-pin octal socketable termination. They are functionally equivalent for all applications.

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

A: The Omron MK3P-13-DC24 maintains identical specifications to the main part. The TE Connectivity KRPA-14DG-24 and KRPA-14DN-24 provide equivalent core functionality but operate across a wider temperature range (-45°C ~ 70°C versus -10°C ~ 40°C) and use silver cadmium oxide contact material instead of pure silver. The KRPA-14DN-24 includes an integrated lighted indicator feature.

Q: Are there packaging differences between these relays?

A: The Omron MK3ZP-2-DC24 is supplied in bulk packaging, while both TE Connectivity parts (KRPA-14DG-24 and KRPA-14DN-24) are supplied in tray packaging. The 11-pin octal socketable termination is identical across all parts.

Q: Do all substitute parts meet RoHS requirements?

A: Yes. The Omron parts are RoHS Compliant, and the TE Connectivity parts are ROHS3 Compliant. All parts meet current environmental compliance standards.

Q: Which substitute part offers the best inventory availability?

A: The KRPA-14DN-24 has the highest inventory level at 2300 units in stock, followed by KRPA-14DG-24 at 866 units, MK3P-13-DC24 at 700 units, and the main part MK3ZP-2-DC24 at 1109 units.
