Key Parameters

Substitute Part Grouping Explanation

Substitution of the G2RL-1A4-CF DC48 is determined by strict equivalence across the following critical parameters:

• Coil voltage specification (48VDC)
• Contact configuration (SPST-NO, 1 Form A)
• Current rating (12A minimum)
• Switching voltage capability (440VAC, 300VDC maximum)
• Mounting method (Through Hole)
• Termination type (PC Pin)
• Seal rating (Sealed - Fully)
• Operating temperature range (-40°C ~ 85°C)
• Contact material composition (Silver Alloy, Cadmium Free)

The G2RL-1A4 DC48 meets all these criteria and is identified as a parametric equivalent. The primary distinction is product status: the original part is obsolete while the substitute is active.

Parameter Comparison

Engineering Selection Recommendations

The G2RL-1A4 DC48 is the direct active equivalent for the obsolete G2RL-1A4-CF DC48. All electrical and mechanical parameters are identical. The substitute part carries RoHS Compliance certification, providing enhanced regulatory alignment for new designs and procurement cycles. Both parts share the same base product number (G2RL-1A), series designation, and export classification codes. Selection of the active substitute ensures continued availability and supply chain continuity without design modification.

Frequently Asked Questions (FAQ)

Q: Can the G2RL-1A4 DC48 be used as a direct replacement for the G2RL-1A4-CF DC48?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters including coil voltage, contact configuration, current rating, switching voltage, mounting type, and termination style. The substitute is the active production equivalent.

Q: What is the primary difference between these two parts?

A: Product status. The G2RL-1A4-CF DC48 is obsolete, while the G2RL-1A4 DC48 is active. The substitute also carries RoHS Compliance certification.

Q: Are there any compatibility concerns with PCB layout or footprint?

A: No. Both parts use identical through-hole PC pin termination and sealed construction. Footprint and mounting requirements are unchanged.

Q: Does the RoHS Compliance status of the substitute affect circuit performance?

A: No. RoHS Compliance relates to material composition and environmental standards, not electrical or switching characteristics. All performance parameters remain identical.

Q: What is the coil voltage tolerance for this relay?

A: The relay must operate at 33.6 VDC minimum and release at 4.8 VDC maximum, establishing the functional voltage window for 48VDC nominal coil specification.

Q: Is this relay suitable for AC switching applications?

A: This relay is rated for switching up to 440VAC at maximum voltage. Verify specific load requirements and switching frequency for your application.
