Substitute Part Grouping Explanation

Substitution eligibility for the MKS3P AC24 is determined by strict equivalence across the following critical parameters:

  • Coil Voltage: 24VAC (exact match required)
  • Contact Form: 3PDT (3 Form C) configuration
  • Contact Rating: 10 A minimum
  • Switching Voltage: 250VAC, 30VDC maximum capability
  • Termination Style: Plug In, 11 Pin (Octal) socket compatibility
  • Mounting Type: Socketable installation method
  • Series: MKS product family

The MKS3P-5 AC24 meets all substitution criteria as a parametric equivalent within the Omron MKS series. Both parts share identical electrical specifications, contact ratings, coil characteristics, and physical termination requirements, enabling direct socket-based replacement in control circuits.

Engineering Selection Recommendations

Both the MKS3P AC24 and MKS3P-5 AC24 are active production parts from Omron Automation and Safety. The MKS3P-5 AC24 carries ROHS3 compliance certification, representing an updated compliance status relative to the base RoHS designation of the MKS3P AC24. Both parts maintain identical electrical performance, contact ratings, coil specifications, and physical termination characteristics. Selection between these parts may be based on compliance documentation requirements, inventory availability, or supply chain considerations, as all functional parameters remain equivalent for direct socket-based substitution.

Frequently Asked Questions (FAQ)

Q: Can the MKS3P-5 AC24 be used as a direct replacement for the MKS3P AC24 in existing installations?

A: Yes. Both relays share identical coil voltage (24VAC), contact form (3PDT), current rating (10 A), switching voltage capability (250VAC, 30VDC), termination style (11 Pin Octal socket), and operating temperature range (-40°C ~ 60°C). Direct socket-based substitution is supported without circuit modification.

Q: What is the significance of the ROHS3 compliance designation on the MKS3P-5 AC24?

A: ROHS3 represents an updated compliance certification status. Both parts are RoHS compliant and suitable for applications requiring hazardous substance restriction compliance. The ROHS3 designation on the MKS3P-5 AC24 reflects current compliance documentation standards.

Q: Are the coil electrical characteristics identical between these two relays?

A: Yes. Both parts operate at 24VAC with a coil current of 96.3 mA and coil resistance of 48.4 Ohms. Must operate voltage is 19.2 VAC and must release voltage is 7.2 VAC for both relays. Operate and release times are both 20 ms.

Q: Do these relays require the same socket type?

A: Yes. Both the MKS3P AC24 and MKS3P-5 AC24 use an 11 Pin Octal plug-in termination style. They are mechanically and electrically compatible with standard MKS series relay sockets.
