Substitute Part Grouping Explanation

Substitute parts for the MKS3P-2 AC220 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• Contact Form: 3PDT (3 Form C)
• Contact Rating (Current): 10 A
• Coil Voltage: 220VAC
• Switching Voltage: 250VAC, 30VDC – Max
• Coil Current: 10.5 mA
• Coil Type: Non Latching
• Mounting Type: Socketable
• Termination Style: Plug In, 11 Pin (Octal)
• Operating Temperature: –40°C to 60°C
• Contact Material: Silver Tin Indium (AgSnIn)
• Coil Resistance: 4.65 kOhms
• Must Operate Voltage: 176 VAC
• Must Release Voltage: 66 VAC
• Operate Time: 20 ms
• Release Time: 20 ms

The identified substitute parts—MKS3P AC220 and MKS3P-5 AC220—maintain complete parametric alignment with the main part across all electrical performance characteristics, mechanical configuration, and environmental specifications. These parts are interchangeable within the same circuit design without modification.

Parameter Comparison

Engineering Selection Recommendations

All three parts—MKS3P-2 AC220, MKS3P AC220, and MKS3P-5 AC220—are active products from Omron Automation and Safety with full RoHS compliance. The MKS3P AC220 carries ROHS3 certification, while MKS3P-2 AC220 and MKS3P-5 AC220 maintain standard RoHS compliance. All parts meet MSL Level 1 (Unlimited) moisture sensitivity requirements and carry identical electrical and mechanical specifications.

Selection between these parts should be based on procurement availability, inventory status, and compliance requirements specific to the application. The parametric equivalence across all critical specifications ensures direct substitution without circuit redesign or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can MKS3P AC220 and MKS3P-5 AC220 be used interchangeably with MKS3P-2 AC220?

A: Yes. All three parts maintain identical electrical performance, contact configuration, coil specifications, and mechanical mounting. They are direct parametric equivalents suitable for drop-in replacement within the same circuit design.

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

A: MKS3P AC220 carries ROHS3 certification, while MKS3P-2 AC220 and MKS3P-5 AC220 maintain RoHS compliance. Both certifications satisfy RoHS requirements; the difference reflects certification revision levels. Application compliance requirements should determine selection if ROHS3 specifically is mandated.

Q: Do these relays require socket bases for installation?

A: Yes. All three parts feature socketable mounting with 11-pin octal termination. Installation requires compatible relay sockets; direct PCB soldering is not applicable.

Q: What is the operating voltage range for these relays?

A: The coil operates at 220VAC nominal. Must Operate Voltage is 176 VAC and Must Release Voltage is 66 VAC, defining the functional voltage window for reliable operation.

Q: Are these parts suitable for high-frequency switching applications?

A: These relays are general purpose devices with 20 ms operate and release times. They are designed for standard industrial control applications, not high-frequency switching. Switching frequency requirements should be evaluated against these timing specifications.
