GSCA01C Equivalent & Substitute Parts Reference

Part Overview

The GSCA01C is a safety limit switch manufactured by Honeywell Sensing and Productivity Solutions, configured as a 1NC/1NO (one normally closed, one normally open) switch. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives from active product lines. The part maintains RoHS compliance and unlimited moisture sensitivity rating (MSL 1), making it suitable for industrial control and safety applications requiring dual-circuit switching capability.

Substitute Part Grouping Explanation

Substitution for the GSCA01C is determined by circuit configuration compatibility and electrical ratings. The original part specifies 1NC/1NO functionality, indicating a dual-circuit switch with one normally closed contact and one normally open contact.

Two substitute candidates are identified:

D4B-2171N (Omron Automation and Safety): Provides SPDT (Single Pole Double Throw) circuit configuration, functionally equivalent to 1NC/1NO switching. This part is active, RoHS3 compliant, and rated for 10A AC at 120V and 6A DC at 30V. Chassis mount configuration with screw terminal termination and IP67 ingress protection.

D4N-4132NPT (Omron Automation and Safety): Provides DPST-NO/NC (Double Pole Single Throw with normally open and normally closed contacts) circuit configuration, offering dual-circuit switching. This part is active, RoHS compliant, and rated for 3A AC at 240V and 270mA DC at 250V. Chassis mount configuration with screw terminal termination and IP67 ingress protection.

Substitution logic is based on:

• Circuit configuration (1NC/1NO equivalent functionality)
• Product status (active alternatives to obsolete part)
• RoHS compliance maintenance
• Moisture sensitivity rating (MSL 1 maintained)
• ECCN classification (EAR99 maintained)

Parameter Comparison

Engineering Selection Recommendations

For D4B-2171N Selection: This substitute is appropriate when the application requires SPDT switching with higher current capacity (10A AC). The part is active with current manufacturing support, ROHS3 compliant, and maintains EAR99 classification. Electrical ratings of 120V AC and 30V DC accommodate standard industrial control voltages. Chassis mount configuration with screw terminals provides standard industrial installation methods.

For D4N-4132NPT Selection: This substitute is appropriate when the application requires explicit dual-circuit switching (DPST-NO/NC) with higher voltage capacity (240V AC). The part is active with current manufacturing support, RoHS compliant, and maintains EAR99 classification and matching HTSUS code (8536.50.9055) to the original GSCA01C. Chassis mount configuration with screw terminals provides standard industrial installation methods.

Both substitutes maintain MSL 1 rating and ECCN EAR99 classification, ensuring compatibility with existing supply chain and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Why is the GSCA01C obsolete and what does this mean for procurement?

A: Obsolete status indicates the part is no longer manufactured by Honeywell Sensing and Productivity Solutions. Active substitutes from Omron Automation and Safety provide equivalent circuit functionality with current manufacturing support and availability.

Q: What is the functional difference between D4B-2171N and D4N-4132NPT?

A: D4B-2171N provides SPDT (Single Pole Double Throw) configuration, functionally equivalent to 1NC/1NO with single-pole switching. D4N-4132NPT provides DPST-NO/NC (Double Pole Single Throw) configuration with dual-pole switching capability. Selection depends on application circuit requirements.

Q: Are both substitutes RoHS compliant?

A: Yes. D4B-2171N is ROHS3 compliant and D4N-4132NPT is RoHS compliant. Both maintain the RoHS compliance status of the original GSCA01C.

Q: Do the substitutes maintain the same moisture sensitivity rating?

A: Yes. Both D4B-2171N and D4N-4132NPT maintain MSL 1 (Unlimited) rating, identical to the GSCA01C.

Q: What are the voltage and current differences between the substitutes?

A: D4B-2171N is rated 10A AC at 120V and 6A DC at 30V. D4N-4132NPT is rated 3A AC at 240V and 270mA DC at 250V. Application voltage and current requirements determine appropriate selection.

Q: Are the substitutes available in the same packaging?

A: Both substitutes are supplied in bulk packaging. Original GSCA01C packaging information is not specified in available data. Confirm packaging requirements with procurement specifications.

Q: Do both substitutes have the same ECCN classification?

A: Yes. Both D4B-2171N and D4N-4132NPT maintain EAR99 classification, identical to the GSCA01C.

Q: What mounting and termination methods do the substitutes use?

A: Both substitutes use chassis mount configuration with screw terminal termination, providing standard industrial installation compatibility.
