Omron MY2-GS AC48 General Purpose Relay - Equivalent & Substitute Parts

Part Overview

The Omron MY2-GS AC48 is a general purpose relay with DPDT (2 Form C) contact configuration and 48VAC coil voltage. This socketable relay is designed for applications requiring 5A contact rating at switching voltages up to 250VAC or 220VDC. The product is currently classified as obsolete, making identification of suitable substitute components essential for system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MY2-GS AC48 is determined by the following critical parameters that must remain consistent:

• Coil Voltage: 48VAC (exact match required)
• Contact Form: DPDT (2 Form C) configuration
• Coil Type: Non Latching
• Mounting Type: Socketable
• Coil Current: 21.1 mA
• Coil Resistance: 788 Ohms
• Operating Temperature Range: -55°C ~ 70°C
• Contact Material: Silver (Ag)

The MY2-GS-R AC48 qualifies as a direct substitute based on these parameters. While the contact rating increases from 5A to 10A, this represents an enhancement that maintains backward compatibility with the original specification. The termination style expansion to include Quick Connect options provides additional installation flexibility without compromising electrical performance.

Parameter Comparison

Engineering Selection Recommendations

The MY2-GS-R AC48 is the manufacturer-recommended substitute for the obsolete MY2-GS AC48. Both components maintain identical electrical characteristics for coil voltage, contact configuration, timing parameters, and operating temperature range. The substitute part carries active product status, ensuring continued availability and supply chain reliability.

The increased contact rating of the MY2-GS-R AC48 (10A versus 5A) provides enhanced current-carrying capacity while maintaining all other specifications. This enhancement does not introduce incompatibility with existing circuit designs rated for the original 5A specification. Both components are RoHS compliant and utilize identical coil resistance and current draw characteristics, ensuring direct functional equivalence in socketable mounting applications.

Frequently Asked Questions (FAQ)

Q: Can the MY2-GS-R AC48 directly replace the MY2-GS AC48 in existing applications?

A: Yes. The MY2-GS-R AC48 maintains identical coil voltage (48VAC), contact form (DPDT), coil current (21.1 mA), coil resistance (788 Ohms), and operating temperature range (-55°C ~ 70°C). The increased contact rating represents a capability enhancement that does not compromise compatibility with circuits designed for the original 5A specification.

Q: What is the significance of the increased contact rating in the substitute part?

A: The MY2-GS-R AC48 provides 10A contact rating compared to the original 5A rating. This allows the substitute to handle higher current loads while maintaining all other electrical and mechanical specifications. Applications limited to 5A operation remain fully compatible.

Q: Are there differences in termination style between these parts?

A: The MY2-GS AC48 uses Plug In termination. The MY2-GS-R AC48 offers both Plug In and Quick Connect - 0.110" (2.8mm) termination options. Both termination styles are compatible with socketable mounting applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the MY2-GS AC48 and MY2-GS-R AC48 are RoHS compliant with MSL rating of 1 (Unlimited). Both utilize silver (Ag) contact material and are classified as general purpose relays within the Omron MY series.

Q: Why is the original part listed as obsolete?

A: The MY2-GS AC48 has reached end-of-life status. The MY2-GS-R AC48 is the active replacement that provides equivalent functionality with enhanced specifications and continued manufacturer support.
