Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete D4GL-1CFA-A is based on the following criteria derived from the provided parameters:

Primary Substitution Logic:

• Identical manufacturer (Omron Automation and Safety)
• Matching circuit configuration (DPST-NO/NC + DPST-NC)
• Identical actuator type (Panel Disconnect)
• Matching ingress protection rating (IP67)
• Identical operating temperature range (-10°C to 55°C)
• Matching moisture sensitivity level (MSL 1)
• Active product status (ensuring ongoing availability and support)

Identified Substitutes: The D4SL-N series (D4SL-N4CFA and D4SL-N4CFA-N) meet the core functional and environmental requirements. Both variants maintain the same circuit topology, environmental protection, and temperature specifications as the original part.

Parameter Variations in Substitutes:

• Current rating differs (1.5A AC / 220mA DC vs. 750mA AC)
• Voltage rating differs (120VAC / 125VDC vs. 240VAC)
• Holding force differs (6kgf vs. 102kgf)
• Conduit thread size differs (M20 vs. PG14.6)
• Termination style varies between screw terminal and connector options

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Screw Terminal Requirement): The D4SL-N4CFA is the active substitute with screw terminal termination, matching the original D4GL-1CFA-A configuration. This part maintains identical circuit topology, environmental ratings, and temperature specifications. The D4SL-N4CFA carries expanded regulatory approvals (CCC, CE, cURus, TUV) compared to the original part.

For Connector-Based Applications: The D4SL-N4CFA-N provides an alternative with connector termination instead of screw terminals. This variant is functionally equivalent to the D4SL-N4CFA with identical electrical and environmental specifications.

Compliance Considerations: Both substitute parts maintain CE, TUV, and cU-series certifications. The D4SL-N series adds CCC approval, providing broader regulatory coverage. All parts maintain MSL 1 rating, indicating no moisture sensitivity constraints during storage or handling.

Application Constraints: Substitution requires evaluation of the following parameter differences: voltage rating (120VAC/125VDC vs. 240VAC), current capacity (1.5A AC vs. 750mA AC), holding force (6kgf vs. 102kgf), and mechanical interface (M20 vs. PG14.6 conduit thread). These differences must be assessed against specific application requirements before implementation.

Frequently Asked Questions (FAQ)

Q: Can the D4SL-N4CFA directly replace the D4GL-1CFA-A in all applications? A: The D4SL-N4CFA maintains identical circuit configuration, actuator type, environmental protection, and temperature range. However, the voltage rating (120VAC/125VDC vs. 240VAC), current capacity (1.5A AC vs. 750mA AC), holding force (6kgf vs. 102kgf), and conduit thread size (M20 vs. PG14.6) differ. Application compatibility depends on whether these parameter differences are acceptable for the specific installation.

Q: What is the difference between D4SL-N4CFA and D4SL-N4CFA-N? A: Both parts are functionally identical with matching electrical specifications, environmental ratings, and temperature ranges. The primary difference is termination style: D4SL-N4CFA uses screw terminals, while D4SL-N4CFA-N uses connector termination. Selection depends on the wiring interface required by the application.

Q: Why is the holding force significantly lower in the D4SL-N series? A: The D4SL-N series is rated at 6kgf holding force compared to the D4GL-1CFA-A at 102kgf. This represents a fundamental design difference between the product lines. Applications requiring the original 102kgf holding force cannot use the D4SL-N series as a substitute.

Q: Are there any regulatory compliance differences between the main part and substitutes? A: The D4GL-1CFA-A carries CE, cULus, and TUV approvals. The D4SL-N series carries CCC, CE, cURus, and TUV approvals. The D4SL-N series provides additional CCC certification. Both maintain identical MSL 1 moisture sensitivity ratings.

Q: What is the impact of the different conduit thread sizes? A: The D4GL-1CFA-A uses PG14.6 conduit threading, while the D4SL-N series uses M20. This mechanical difference requires evaluation of the mounting interface and conduit compatibility in the target application.

Q: Can the D4SL-N series handle the same voltage as the original part? A: No. The D4GL-1CFA-A is rated for 240VAC operation, while the D4SL-N series is rated for 120VAC and 125VDC. The voltage rating difference must be evaluated against the application's power supply specifications.
