Omron MY2-J DC48 General Purpose Relay - Equivalent & Substitute Parts

Part Overview

The Omron MY2-J DC48 is a general purpose relay with DPDT (2 Form C) contact configuration rated for 5A at 48VDC coil voltage. This socketable relay is designed for switching applications up to 250VAC or 125VDC maximum. The MY2-J DC48 is classified as obsolete, making identification of active equivalent parts essential for new designs and system maintenance where continued availability is required.

Key Parameters

Substitute Part Grouping Explanation

The MY2 DC48 (S) qualifies as a parametric equivalent to the MY2-J DC48 based on the following critical parameters:

• Coil Voltage: Both parts operate at 48VDC
• Contact Form: Both are DPDT (2 Form C) configuration
• Contact Rating: Both rated for 5A switching current
• Switching Voltage: Both support 250VAC, 125VDC maximum
• Mounting Type: Both are socketable with plug-in termination
• Coil Characteristics: Identical coil current (18.8 mA), coil resistance (2.56 kOhms), and timing specifications (20 ms operate/release)
• Operating Temperature Range: Both rated -55°C to 70°C
• Contact Material: Both use silver (Ag) contacts

The primary distinction is product status: MY2-J DC48 is obsolete while MY2 DC48 (S) is active, with improved compliance certifications (RoHS Compliant, REACH Unaffected).

Parameter Comparison

Engineering Selection Recommendations

The MY2 DC48 (S) is the direct active equivalent for the obsolete MY2-J DC48. All electrical and mechanical parameters are identical, ensuring drop-in compatibility in existing socket-based installations. The MY2 DC48 (S) provides the additional advantage of active product status with current RoHS compliance and REACH unaffected certification, making it suitable for new designs and long-term supply chain continuity. Both parts share the same ECCN (EAR99) and HTSUS classification (8536.41.0020).

Frequently Asked Questions (FAQ)

Q: Can the MY2 DC48 (S) directly replace the MY2-J DC48 in existing applications?

A: Yes. The MY2 DC48 (S) is electrically and mechanically identical to the MY2-J DC48. Both parts have the same coil voltage (48VDC), contact configuration (DPDT), current rating (5A), switching voltage limits (250VAC/125VDC), and timing characteristics (20 ms operate/release). The socketable mounting and plug-in termination are identical, allowing direct socket substitution.

Q: What is the difference between MY2-J DC48 and MY2 DC48 (S)?

A: The primary differences are product status and compliance certifications. The MY2-J DC48 is obsolete, while the MY2 DC48 (S) is an active product with RoHS compliance and REACH unaffected status. All functional electrical and mechanical parameters are identical.

Q: Are there packaging differences between these parts?

A: The MY2-J DC48 is supplied with standard packaging, while the MY2 DC48 (S) is supplied in bulk packaging. Both parts are socketable relays with identical form factors and pin configurations.

Q: What is the coil resistance and current draw for these relays?

A: Both the MY2-J DC48 and MY2 DC48 (S) have a coil resistance of 2.56 kOhms and draw 18.8 mA at 48VDC. The must-operate voltage is 38.4 VDC and the must-release voltage is 4.8 VDC.

Q: Are these relays suitable for high-temperature applications?

A: Both relays are rated for operation across -55°C to 70°C. Applications requiring operation outside this range require alternative relay selection.

Q: What contact material is used in these relays?

A: Both the MY2-J DC48 and MY2 DC48 (S) use silver (Ag) contacts, providing reliable switching performance for general purpose applications.
