Omron G2A-4341P DC48 Equivalent & Substitute Parts

Part Overview

The Omron G2A-4341P DC48 is a general purpose relay with 4PDT (4 Form C) contact configuration, rated for 500 mA at 48VDC coil voltage. This through-hole mounted relay is designed for applications requiring multiple independent switching circuits with low-level control signals.

The G2A-4341P DC48 is classified as obsolete. Locating active production alternatives is necessary for new designs, long-term supply chain continuity, and applications requiring enhanced environmental specifications or higher contact ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the G2A-4341P DC48 is determined by the following critical parameters:

• Coil Voltage: Must be 48VDC to maintain control circuit compatibility
• Contact Form: Must be 4PDT (4 Form C) to preserve switching circuit topology
• Mounting Type: Must be through-hole with PC pin termination for PCB compatibility
• Switching Voltage Rating: Must support 250VAC, 125VDC maximum to handle load specifications
• Must Operate/Release Voltages: Must match 38.4 VDC / 4.8 VDC to ensure reliable actuation within the control system voltage window

The Omron MYQ4Z-02 DC48 meets all substitution criteria. While it provides higher contact current rating (1 A versus 500 mA), this represents an upgrade that maintains backward compatibility with the original application requirements. The MYQ4Z-02 DC48 is an active production part with sealed construction and extended operating temperature range.

Engineering Selection Recommendations

The MYQ4Z-02 DC48 is the qualified substitute for the obsolete G2A-4341P DC48. Selection is based on the following engineering factors:

Product Status: The G2A-4341P DC48 is obsolete. The MYQ4Z-02 DC48 is an active production part with confirmed inventory availability, ensuring long-term supply chain viability.

Compliance & Certifications: The MYQ4Z-02 DC48 carries RoHS compliance certification, meeting modern regulatory requirements for new equipment designs. Both parts share identical ECCN and HTSUS classifications.

Functional Compatibility: Both relays maintain identical coil voltage (48VDC), contact form (4PDT), switching voltage rating (250VAC, 125VDC), and actuation thresholds (38.4 VDC operate, 4.8 VDC release). These parameters ensure direct functional substitution in existing control circuits.

Performance Enhancements: The MYQ4Z-02 DC48 provides higher contact current rating (1 A versus 500 mA), lower coil current draw (18.5 mA versus 22 mA), sealed construction for environmental protection, and extended operating temperature range (-55°C to 60°C versus -10°C to 40°C).

Timing Considerations: The MYQ4Z-02 DC48 exhibits slightly longer switching times (20 ms operate/release versus 15 ms). Applications with strict timing requirements must evaluate this 5 ms difference against system performance specifications.

Frequently Asked Questions (FAQ)

Q: Can the MYQ4Z-02 DC48 directly replace the G2A-4341P DC48 in existing designs?

A: Yes. Both relays share identical coil voltage, contact form, switching voltage rating, and actuation thresholds. The MYQ4Z-02 DC48 is a functional equivalent with enhanced specifications. PCB footprint compatibility must be verified during physical integration.

Q: What is the significance of the higher 1 A contact rating on the MYQ4Z-02 DC48?

A: The MYQ4Z-02 DC48 supports higher load currents (1 A maximum) compared to the G2A-4341P DC48 (500 mA maximum). This provides design margin for applications approaching the original 500 mA limit and enables use in higher-current switching scenarios without relay replacement.

Q: Does the sealed construction of the MYQ4Z-02 DC48 affect compatibility?

A: No. Sealed construction provides enhanced environmental protection against moisture and contaminants. This is a performance upgrade that does not compromise electrical or mechanical compatibility with the original application.

Q: Are the 5 ms longer switching times of the MYQ4Z-02 DC48 significant?

A: Switching time differences (20 ms versus 15 ms) must be evaluated against application timing requirements. For most general-purpose relay applications, this difference is not critical. Applications with strict timing specifications require explicit timing validation.

Q: What is the coil current difference between these relays?

A: The MYQ4Z-02 DC48 draws 18.5 mA compared to 22 mA for the G2A-4341P DC48. The lower coil current reduces control circuit power consumption and heat generation, providing a secondary benefit in the substitution.

Q: Is RoHS compliance required for my application?

A: RoHS compliance is mandatory for equipment sold in the European Union and many other markets. The MYQ4Z-02 DC48 carries RoHS certification; the G2A-4341P DC48 status is not specified. New designs should specify the RoHS-compliant MYQ4Z-02 DC48.
