Omron MY2Z DC12 General Purpose Relay - Equivalent & Substitute Parts

Part Overview

The Omron MY2Z DC12 is an active general purpose relay featuring DPDT (2 Form C) contact configuration with 5A contact rating and 12VDC coil voltage. This socketable relay is designed for standard switching applications requiring reliable electromagnetic actuation. Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when inventory constraints require component alternatives that maintain functional and electrical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MY2Z DC12 are classified based on strict electrical and mechanical parameter alignment:

Parametric Equivalent Classification: Parts that maintain identical or functionally equivalent specifications across all critical parameters including coil voltage, contact form, contact rating, coil current, mounting type, and termination style.

Similar Classification: Parts that share the same functional contact configuration and coil voltage but may exhibit variations in secondary parameters such as switching voltage maximum, operating temperature range, or contact material composition. These parts are suitable for applications where the specific parameter variations do not conflict with circuit requirements.

The following parameters are mandatory for substitution consideration:

• Coil Voltage: 12VDC
• Contact Form: DPDT (2 Form C)
• Contact Rating: 5 A minimum
• Mounting Type: Socketable
• Termination Style: Plug In
• Coil Current: 75 mA

Engineering Selection Recommendations

MY2 DC12 (S) - Parametric Equivalent: This Omron part maintains complete electrical and mechanical equivalence to the MY2Z DC12. Both parts are RoHS compliant and share identical coil specifications, contact ratings, and operating parameters. Selection of this substitute provides direct functional replacement with no circuit redesign required. Higher inventory availability (2384 pcs) supports supply chain continuity.

KHAU-11D12-12 - Similar Substitute: This TE Connectivity Potter & Brumfield relay maintains core functional compatibility through identical coil voltage, contact form, contact rating, and coil current. The part is RoHS non-compliant and REACH affected, which may restrict use in regulated applications or regions with environmental compliance requirements. The maximum switching voltage is reduced to 240VAC compared to 250VAC for the primary part. The operating temperature minimum is -45°C versus -55°C for the primary part. Selection of this substitute requires verification that the reduced switching voltage maximum and narrower temperature range do not conflict with application requirements. This part is suitable only for applications where environmental compliance restrictions do not apply.

Frequently Asked Questions (FAQ)

Q: Can MY2 DC12 (S) be used as a direct replacement for MY2Z DC12?

A: Yes. The MY2 DC12 (S) is a parametric equivalent with identical electrical specifications, contact configuration, coil voltage, and mounting characteristics. No circuit modifications are required for substitution.

Q: What are the key differences between MY2Z DC12 and KHAU-11D12-12?

A: Both parts share 12VDC coil voltage, DPDT contact form, 5A contact rating, and socketable mounting. The KHAU-11D12-12 has a reduced maximum switching voltage (240VAC vs. 250VAC), narrower operating temperature range (-45°C to 70°C vs. -55°C to 70°C), and uses Silver Cadmium Oxide contact material instead of Silver. Additionally, the KHAU-11D12-12 is RoHS non-compliant and REACH affected.

Q: Are there compliance considerations when selecting substitute parts?

A: Yes. The MY2Z DC12 and MY2 DC12 (S) are both RoHS compliant. The KHAU-11D12-12 is RoHS non-compliant and REACH affected. Applications subject to RoHS or REACH regulations must use compliant parts. Verify regulatory requirements before selecting the KHAU-11D12-12.

Q: What is the significance of the socketable mounting type?

A: Socketable mounting indicates the relay is designed for plug-in installation into a relay socket base. All three parts share this mounting characteristic, ensuring mechanical compatibility with standard relay socket installations.

Q: Can KHAU-11D12-12 be used in applications requiring -55°C operation?

A: No. The KHAU-11D12-12 operating temperature minimum is -45°C. Applications requiring operation at -55°C must use MY2Z DC12 or MY2 DC12 (S).

Q: What is the impact of different contact materials on relay performance?

A: The MY2Z DC12 and MY2 DC12 (S) use Silver (Ag) contact material. The KHAU-11D12-12 uses Silver Cadmium Oxide (AgCdO). Contact material affects electrical conductivity, wear characteristics, and arc resistance. Verify that application switching conditions are compatible with the specified contact material before substitution.
