MK2P-I-DC6 Equivalent & Substitute Parts

Part Overview

The MK2P-I-DC6 is a general purpose relay manufactured by Omron Automation and Safety, featuring a DPDT (2 Form C) contact configuration with 10A contact rating and 6VDC coil voltage. This socketable, 8-pin octal relay is designed for general switching applications requiring dual-pole, dual-throw functionality.

The MK2P-I-DC6 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for applications currently utilizing this relay in production or maintenance scenarios.

Substitute Part Grouping Explanation

Substitute parts for the MK2P-I-DC6 are identified based on strict electrical and mechanical compatibility criteria. The following parameters must match or be compatible:

• Coil voltage: 6VDC (exact match required)
• Contact form: DPDT (2 Form C) (exact match required)
• Contact rating: 10A minimum (exact match required)
• Mounting type: Socketable (exact match required)
• Termination style: Plug In, 8 Pin (Octal) (exact match required)
• Coil type: Non Latching (exact match required)

The KRPA-11DG-6 meets all mandatory substitution criteria for the MK2P-I-DC6.

Parameter Comparison

Engineering Selection Recommendations

The KRPA-11DG-6 is the qualified substitute for the obsolete MK2P-I-DC6. Both relays share identical electrical and mechanical specifications for coil voltage, contact configuration, current rating, and termination style.

The KRPA-11DG-6 offers the advantage of active product status, ensuring ongoing availability and supply chain continuity. The substitute part demonstrates superior operating temperature range (-45°C ~ 70°C versus -10°C ~ 40°C) and lower coil current draw (188 mA versus 255 mA), which may provide operational benefits in temperature-sensitive or power-constrained applications.

The KRPA-11DG-6 is ROHS3 compliant, supporting modern regulatory requirements. Switching voltage specification for the substitute (240VAC maximum) is slightly lower than the original part (250VAC, 250VDC maximum); applications operating at or near maximum switching voltage limits should be evaluated for compatibility.

Frequently Asked Questions (FAQ)

Q: Can the KRPA-11DG-6 directly replace the MK2P-I-DC6 in existing applications?

A: Yes. Both relays share identical coil voltage (6VDC), contact form (DPDT), current rating (10A), mounting type (socketable), and 8-pin octal termination. Direct socket substitution is mechanically and electrically compatible.

Q: What are the key differences between these two relays?

A: The primary differences are product status (MK2P-I-DC6 is obsolete; KRPA-11DG-6 is active), operating temperature range (KRPA-11DG-6 supports -45°C ~ 70°C versus -10°C ~ 40°C), coil current (KRPA-11DG-6 draws 188 mA versus 255 mA), and contact material composition (Silver Cadmium Oxide versus Silver). The KRPA-11DG-6 is ROHS3 compliant.

Q: Are there any switching voltage limitations when substituting?

A: The KRPA-11DG-6 specifies 240VAC maximum switching voltage, compared to 250VAC, 250VDC maximum for the MK2P-I-DC6. Applications operating above 240VAC should be evaluated to confirm compatibility with the substitute part's rating.

Q: What is the impact of different coil resistance values?

A: The KRPA-11DG-6 has 32 Ohms coil resistance versus 24.6 Ohms for the MK2P-I-DC6. This difference, combined with lower coil current (188 mA versus 255 mA), results in reduced power consumption. Existing drive circuits designed for the original part will operate the substitute within specified parameters.

Q: Does the contact material difference affect application suitability?

A: The KRPA-11DG-6 uses Silver Cadmium Oxide contacts versus Silver for the MK2P-I-DC6. Both materials are suitable for general purpose switching applications. Contact material selection depends on specific load characteristics and application requirements; no universal compatibility issue exists between these materials for standard relay applications.

Q: Is the KRPA-11DG-6 available in the same packaging format?

A: The KRPA-11DG-6 is supplied in tray packaging. Both relays feature identical 8-pin octal socketable termination, ensuring mechanical compatibility in relay socket installations.
