MK2PD-I-DC24 Equivalent & Substitute Parts

Part Overview

The MK2PD-I-DC24 is a general purpose relay manufactured by Omron Automation and Safety, featuring a DPDT (2 Form C) contact configuration with a 24VDC coil and 10A contact rating. This socketable, 8-pin octal relay is designed for industrial control applications requiring reliable switching of AC and DC loads.

The MK2PD-I-DC24 is classified as obsolete. Identifying suitable substitute parts is necessary to maintain system continuity, ensure component availability for new designs, and support ongoing maintenance of existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MK2PD-I-DC24 are identified based on the following critical parameters that must match or remain compatible:

• Coil voltage: 24VDC
• Contact form: DPDT (2 Form C)
• Contact rating: 10A minimum
• Mounting type: Socketable
• Termination style: Plug In, 8 Pin (Octal)
• Coil type: Non Latching
• Must operate and release voltages within acceptable ranges

The MKS2P-D DC24 meets these core substitution criteria. While minor variations exist in switching voltage maximum ratings, operating temperature range, and contact material composition, the relay maintains functional equivalence for standard industrial control applications.

Parameter Comparison

Engineering Selection Recommendations

The MKS2P-D DC24 is the direct substitute for the obsolete MK2PD-I-DC24. Both relays are manufactured by Omron Automation and Safety and share identical core electrical specifications: 24VDC coil, DPDT contact configuration, 10A contact rating, and 8-pin octal socketable termination.

The MKS2P-D DC24 is classified as active product status, ensuring ongoing availability and supply chain continuity. The substitute part is RoHS compliant, providing compliance advantage over the original part.

Key differences exist in DC switching voltage maximum (30VDC versus 250VDC), operating temperature range (-40°C to 60°C versus -10°C to 40°C), and release time (40 ms versus 20 ms). These differences must be evaluated against specific application requirements. The MKS2P-D DC24 offers extended temperature operation and improved contact material composition (AgSnIn versus Ag), which may provide enhanced performance in demanding environments.

Frequently Asked Questions (FAQ)

Q: Can the MKS2P-D DC24 directly replace the MK2PD-I-DC24 in existing installations?

A: Yes. Both relays share identical coil voltage (24VDC), contact form (DPDT), contact rating (10A), mounting type (socketable), and termination style (8-pin octal). Physical and electrical compatibility is confirmed for standard industrial control applications.

Q: What is the significance of the different DC switching voltage ratings?

A: The MK2PD-I-DC24 specifies 250VDC maximum switching voltage, while the MKS2P-D DC24 specifies 30VDC maximum. Applications requiring DC switching above 30V must retain the original part or identify alternative substitutes. For AC switching applications, both relays are rated to 250VAC.

Q: How does the extended operating temperature range of the MKS2P-D DC24 affect substitution?

A: The MKS2P-D DC24 operates from -40°C to 60°C, compared to -10°C to 40°C for the MK2PD-I-DC24. This extended range provides greater flexibility for applications in temperature-extreme environments. Applications within the original temperature range experience no adverse effects from this specification difference.

Q: What is the impact of the 20 ms difference in release time?

A: The MK2PD-I-DC24 releases in 20 ms, while the MKS2P-D DC24 releases in 40 ms. Applications with strict timing requirements must evaluate whether the longer release time affects system performance. For most general purpose control applications, this difference is not critical.

Q: Are there packaging differences between these relays?

A: The MK2PD-I-DC24 is packaged as individual units, while the MKS2P-D DC24 is supplied in bulk packaging. Both maintain identical form factor and socketable 8-pin octal termination for direct mechanical compatibility.

Q: What compliance certifications apply to the substitute part?

A: The MKS2P-D DC24 is RoHS compliant. Both parts carry ECCN EAR99 classification and HTSUS code 8536.41.0050. Moisture sensitivity level is 1 (Unlimited) for both relays.
