D4BS-2BFS Equivalent & Substitute Parts

Part Overview

The D4BS-2BFS is an interlock non-locking DPST switch manufactured by Omron Automation and Safety. This panel disconnect switch is rated for 10A AC at 120VAC with IP67 ingress protection and operates across -40°C to 80°C. The product is currently obsolete, making equivalent substitute parts necessary for system maintenance, repair, and component sourcing in applications where this switch was originally specified.

Key Parameters

Substitute Part Grouping Explanation

The D4BS-2AFS qualifies as a direct substitute for the D4BS-2BFS based on the following critical parameters:

• Circuit Configuration: Both parts maintain DPST-NC (Double Pole Single Throw - Normally Closed) configuration
• Current and Voltage Ratings: Identical 10A AC at 120VAC specifications
• Mechanical Compatibility: Matching holding force (2kgf), actuator type (Panel Disconnect), termination style (Screw Terminal), and conduit thread size (G1/2)
• Environmental Specifications: Identical operating temperature range (-40°C to 80°C) and IP67 ingress protection rating
• Regulatory Compliance: Both parts carry CE, CSA, and UL approvals
• Series Alignment: Both belong to the D4BS series

The primary distinction is product status: the D4BS-2BFS is obsolete, while the D4BS-2AFS is active and available in inventory.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Can the D4BS-2AFS directly replace the D4BS-2BFS in existing installations?

A: Yes. Both parts are identical in electrical rating (10A AC at 120VAC), circuit configuration (DPST-NC), mechanical interface (Panel Disconnect with Screw Terminal), environmental performance (IP67, -40°C to 80°C), and regulatory approvals (CE, CSA, UL). Direct substitution is supported without circuit or mechanical modifications.

Q: What is the difference between the D4BS-2BFS and D4BS-2AFS?

A: The primary difference is product status. The D4BS-2BFS is obsolete, while the D4BS-2AFS is an active product with current manufacturing and inventory support. All functional and performance parameters are identical.

Q: Are there packaging differences between these parts?

A: The D4BS-2AFS is supplied in Bulk packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: Does the D4BS-2AFS meet current environmental and compliance standards?

A: Yes. The D4BS-2AFS is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What parameters determine substitution eligibility for the D4BS-2BFS?

A: Substitution is based on matching circuit configuration (DPST-NC), current and voltage ratings (10A AC at 120VAC), mechanical interface specifications (Panel Disconnect, Screw Terminal, G1/2 conduit thread), holding force (2kgf), operating temperature range (-40°C to 80°C), ingress protection (IP67), and regulatory approvals (CE, CSA, UL).
