MK2PD-S-DC12 Equivalent & Substitute Parts

Part Overview

The MK2PD-S-DC12 is a general purpose relay manufactured by Omron Automation and Safety, featuring a DPDT (2 Form C) contact configuration with a 12VDC coil and 10A contact rating. This socketable, 8-pin octal relay is designed for general-purpose switching applications requiring dual-pole, dual-throw functionality.

The MK2PD-S-DC12 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain system functionality and ensure continued availability for replacement and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MK2PD-S-DC12 is based on strict equivalence of the following critical parameters:

• Coil voltage: 12VDC
• Contact configuration: DPDT (2 Form C)
• Contact current rating: 10 A
• Mounting type: Socketable
• Termination style: Plug In, 8 Pin (Octal)
• Coil type: Non Latching

The MKS2PIDC12 meets all these core requirements and is therefore classified as a direct substitute. Both relays share identical coil voltage, contact form, current rating, and physical mounting characteristics, enabling functional replacement in applications designed for the MK2PD-S-DC12.

Parameter Comparison

Engineering Selection Recommendations

The MKS2PIDC12 is the active equivalent for the obsolete MK2PD-S-DC12. Both relays are manufactured by Omron Automation and Safety and share identical electrical and mechanical specifications for coil voltage, contact configuration, current rating, and physical form factor.

The MKS2PIDC12 offers an extended operating temperature range (-40°C ~ 60°C versus -10°C ~ 40°C) and improved coil efficiency (112 mA versus 126 mA). The MKS2PIDC12 is ROHS3 compliant, whereas the MK2PD-S-DC12 compliance status is not specified. Both parts maintain REACH Unaffected and EAR99 ECCN classifications.

For applications requiring DC switching above 30V, the MK2PD-S-DC12 specification of 250VDC maximum switching voltage should be noted against the MKS2PIDC12 specification of 30VDC maximum. Contact material differs between the two relays: the MK2PD-S-DC12 uses silver (Ag), while the MKS2PIDC12 uses silver tin indium (AgSnIn).

Frequently Asked Questions (FAQ)

Q: Can the MKS2PIDC12 directly replace the MK2PD-S-DC12 in existing applications?

A: Yes. Both relays share identical coil voltage (12VDC), contact configuration (DPDT), current rating (10A), mounting type (socketable), and termination style (8-pin octal). The MKS2PIDC12 is the active equivalent for the obsolete MK2PD-S-DC12.

Q: What are the differences in switching voltage specifications?

A: The MK2PD-S-DC12 is rated for 250VAC and 250VDC maximum switching voltage. The MKS2PIDC12 is rated for 250VAC and 30VDC maximum switching voltage. Applications requiring DC switching above 30V should reference the original MK2PD-S-DC12 specification.
