Omron MY2K DC12 General Purpose Relay - Equivalent & Substitute Parts

Part Overview

The Omron MY2K DC12 is a general purpose relay with DPDT (2 Form C) contact configuration and 12VDC coil voltage. This socketable relay is designed for applications requiring 3A contact rating at 250VAC or 125VDC maximum switching voltage. The part is currently active in production with RoHS compliance and unlimited moisture sensitivity rating. Alternative models may be required due to inventory constraints, specific compliance requirements, or application-specific performance parameters such as contact rating, coil current, or operating temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MY2K DC12 is determined by strict alignment with the following critical parameters: coil voltage (12VDC), contact form (DPDT), mounting type (socketable), and termination style (plug in). Parts meeting these core requirements are classified as parametric equivalents. Parts that maintain the same coil voltage, contact form, and mounting configuration but differ in contact rating, coil current, operating temperature range, or coil type are classified as similar alternatives suitable for applications where the performance variance is acceptable.

The MY2K DC12 has two substitute relationships:

Parametric Equivalent: MY2K-US-DC12 matches all critical parameters including coil voltage, contact form, mounting type, and termination style. This variant differs only in RoHS certification status (ROHS3 vs. RoHS Compliant) and base product number designation.

Similar Alternative: KHAU-11D12-12 (TE Connectivity Potter & Brumfield) maintains the same coil voltage (12VDC), contact form (DPDT), mounting type (socketable), and termination style (plug in). However, this part differs in contact rating (5A vs. 3A), coil type (non-latching vs. latching dual coil), coil current (75 mA vs. 110 mA), operating temperature range (-45°C ~ 70°C vs. -55°C ~ 60°C), and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

MY2K-US-DC12 is the primary parametric equivalent for the MY2K DC12. Both parts are manufactured by Omron, maintain identical electrical and mechanical specifications, and are active products. The MY2K-US-DC12 carries ROHS3 compliance, which supersedes the standard RoHS Compliant designation of the original part. Selection between these two variants should be based on specific compliance documentation requirements for the end application.

KHAU-11D12-12 is a similar alternative suitable only for applications where the performance differences are acceptable. This TE Connectivity part provides higher contact rating (5A vs. 3A), lower coil current (75 mA vs. 110 mA), and faster release time (6 ms vs. 15 ms). However, it operates as a non-latching relay rather than latching dual coil, features a higher coil resistance (160 Ohms vs. 110 Ohms), and is RoHS non-compliant. The KHAU-11D12-12 is suitable only for applications that do not require latching functionality and can accommodate RoHS non-compliance. The wider operating temperature range (-45°C ~ 70°C) may be advantageous in certain thermal environments.

Frequently Asked Questions (FAQ)

Q: Can MY2K-US-DC12 be used as a direct replacement for MY2K DC12?

A: Yes. Both parts share identical coil voltage (12VDC), contact form (DPDT), contact rating (3A), switching voltage (250VAC, 125VDC), mounting type (socketable), termination style (plug in), coil type (latching dual coil), and operating specifications. The primary difference is RoHS certification status. Direct substitution is supported from an electrical and mechanical standpoint.

Q: Is KHAU-11D12-12 a direct replacement for MY2K DC12?

A: No. While KHAU-11D12-12 maintains the same coil voltage, contact form, and socketable mounting, it differs in critical functional parameters. The KHAU-11D12-12 is a non-latching relay with 5A contact rating, compared to the MY2K DC12's latching dual coil configuration with 3A rating. Substitution is only appropriate for applications that do not require latching functionality and can operate with the higher contact rating and lower coil current.

Q: What are the key differences between latching and non-latching relay types?

A: The MY2K DC12 is a latching dual coil relay, meaning it maintains its contact state after the coil is de-energized until a separate release signal is applied. The KHAU-11D12-12 is non-latching, meaning contacts return to their original state immediately upon coil de-energization. Application requirements determine which type is necessary.

Q: Does RoHS compliance affect substitution decisions?

A: RoHS compliance is a regulatory requirement for specific markets and applications. The MY2K DC12 is RoHS Compliant, MY2K-US-DC12 is ROHS3 Compliant, and KHAU-11D12-12 is RoHS non-compliant. Selection must align with the regulatory requirements of the target market and end-use application.

Q: Can KHAU-11D12-12 be used in applications requiring lower coil current?

A: Yes. The KHAU-11D12-12 draws 75 mA compared to the MY2K DC12's 110 mA, representing a 32% reduction in coil current. This may be advantageous in power-constrained applications. However, the non-latching functionality and RoHS non-compliance status must be evaluated against application requirements.

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

A: Socketable mounting indicates the relay is designed for plug-in connection to a standardized socket base. All three parts (MY2K DC12, MY2K-US-DC12, and KHAU-11D12-12) support this mounting configuration, ensuring mechanical compatibility with socket-based installations.
