Equivalent & Substitute Parts for D4GL-1CFA-A4

Part Overview

The D4GL-1CFA-A4 is an interlock solenoid release switch manufactured by Omron Automation and Safety. This DPST (Double Pole Single Throw) device functions as a panel disconnect actuator with dual circuit configuration (DPST-NO/NC + DPST-NC), rated for 240VAC at 750mA with 24VDC supply voltage. The product is classified as obsolete, necessitating identification of active equivalent alternatives to maintain system functionality and ensure continued availability for replacement and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D4GL-1CFA-A4 is determined by the following critical parameters:

• Manufacturer: Omron Automation and Safety (same manufacturer ensures design compatibility)
• Type: Solenoid Release (functional category match)
• Circuit Configuration: DPST-NO/NC + DPST-NC (identical dual circuit requirement)
• Actuator Type: Panel Disconnect (mechanical interface requirement)
• Ingress Protection: IP67 - Dust Tight, Waterproof (environmental sealing specification)
• Operating Temperature Range: -10°C ~ 55°C (thermal operating envelope)
• Approval Agencies: CE, cULus, TUV (regulatory compliance baseline)

The substitute parts D4SL-N4CFA and D4SL-N4CFA-N satisfy all mandatory substitution criteria. Both are active products from the D4SL-N series, maintaining identical circuit configuration, actuator type, ingress protection rating, operating temperature range, and regulatory approvals. The primary distinction between substitutes is termination style: D4SL-N4CFA uses screw terminal (matching the original), while D4SL-N4CFA-N uses connector termination.

Parameter Comparison

Engineering Selection Recommendations

Both D4SL-N4CFA and D4SL-N4CFA-N are qualified substitutes for the obsolete D4GL-1CFA-A4. Selection between the two active alternatives depends on termination interface requirements:

D4SL-N4CFA is the primary substitute when screw terminal connection is required, maintaining direct compatibility with existing wiring harnesses and terminal blocks designed for the original D4GL-1CFA-A4.

D4SL-N4CFA-N is the appropriate selection when connector-based termination is preferred or when system redesign permits connector integration. This variant offers the same functional and environmental specifications with alternative connection methodology.

Both substitutes carry expanded regulatory approvals (CCC, CE, cURus, TUV) compared to the original part, ensuring compliance across broader market jurisdictions. Active product status guarantees continued manufacturing support and availability for future procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N4CFA and D4SL-N4CFA-N be used interchangeably with D4GL-1CFA-A4?

A: Both D4SL-N series parts are functionally equivalent substitutes. Interchangeability depends on termination interface compatibility. D4SL-N4CFA with screw terminal provides direct replacement capability. D4SL-N4CFA-N with connector termination requires interface adaptation or system redesign.

Q: What is the primary reason for substitution?

A: The D4GL-1CFA-A4 is classified as obsolete. The D4SL-N4CFA and D4SL-N4CFA-N are active products from Omron's current product line, ensuring long-term availability and manufacturing support.

Q: Are the electrical specifications compatible?

A: Both substitute parts maintain identical circuit configuration (DPST-NO/NC + DPST-NC), actuator type (Panel Disconnect), ingress protection (IP67), and operating temperature range (-10°C ~ 55°C) as the original part. Voltage and current ratings differ between the original and substitutes; system integration must account for these electrical parameter variations.

Q: What certifications do the substitute parts carry?

A: D4SL-N4CFA and D4SL-N4CFA-N carry CCC, CE, cURus, and TUV approvals, providing broader regulatory compliance than the original D4GL-1CFA-A4 (CE, cULus, TUV).

Q: How do termination styles affect installation?

A: Screw terminal (D4SL-N4CFA) connects directly to wire leads or terminal blocks. Connector termination (D4SL-N4CFA-N) requires mating connector assembly. Installation method selection depends on existing system infrastructure and wiring methodology.
