Key Parameters

Substitute Part Grouping Explanation

Substitution of the G2RL-2A4-CF DC48 is determined by strict equivalence across the following critical parameters:

• Coil Voltage: 48VDC (must operate at 33.6 VDC minimum, release at 4.8 VDC maximum)
• Contact Configuration: DPST-NO (2 Form A) with 8A current rating
• Switching Capability: 440VAC, 300VDC maximum
• Mounting Interface: Through-hole PC pin termination
• Environmental Sealing: Fully sealed construction
• Contact Material Composition: Silver alloy, cadmium-free
• Operating Temperature: -40°C to 85°C range
• Coil Resistance: 5.36 kOhms

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. Deviations in any of these parameters result in functional or compatibility incompatibility.

Parameter Comparison

Engineering Selection Recommendations

The G2RL-2A4 DC48 is the direct parametric equivalent and recommended substitute for the obsolete G2RL-2A4-CF DC48. Both parts are manufactured by Omron Electronics Inc-EMC Div within the G2RL series and maintain identical electrical and mechanical specifications across all critical parameters.

The substitute part offers the advantage of active product status, ensuring continued availability and supply chain support. The G2RL-2A4 DC48 carries RoHS compliance certification, meeting current environmental and regulatory standards for electronic component manufacturing.

No functional or compatibility compromises exist between the main part and substitute. Direct replacement is supported without circuit redesign or application modification.

Frequently Asked Questions (FAQ)

Q: Can the G2RL-2A4 DC48 be used as a direct replacement for the G2RL-2A4-CF DC48?

A: Yes. Both relays share identical coil voltage (48VDC), contact configuration (DPST-NO, 2 Form A), current rating (8A), switching voltage capability (440VAC, 300VDC max), mounting type (through-hole), seal rating (fully sealed), contact material (silver alloy, cadmium-free), and operating temperature range (-40°C to 85°C). Direct substitution is supported without modification.

Q: What is the difference between the G2RL-2A4-CF DC48 and G2RL-2A4 DC48?

A: The primary difference is product status. The G2RL-2A4-CF DC48 is obsolete, while the G2RL-2A4 DC48 is active and carries RoHS compliance certification. All electrical and mechanical parameters are identical.

Q: Are there any compatibility concerns when substituting the G2RL-2A4 DC48 for the G2RL-2A4-CF DC48?

A: No compatibility concerns exist. Both relays are through-hole mounted with PC pin termination, operate at identical coil voltage and current specifications, and maintain the same contact rating and switching voltage limits. PCB footprint and pin configuration are compatible.

Q: Does the substitute part meet current regulatory requirements?

A: Yes. The G2RL-2A4 DC48 is RoHS compliant and carries current environmental certifications. The original G2RL-2A4-CF DC48 is obsolete and no longer supported by the manufacturer.

Q: What is the coil resistance of the substitute relay?

A: The coil resistance of the G2RL-2A4 DC48 is 5.36 kOhms, identical to the original part. This ensures equivalent power consumption and drive circuit requirements.
