HS5E-B4405-G Interlock Solenoid Release DPST — Equivalent & Substitute Parts

Part Overview

The HS5E-B4405-G is an interlock solenoid release switch manufactured by IDEC, classified as a DPST (Double Pole Single Throw) device with combined NO/NC and NC circuits. This component functions as a panel disconnect actuator with a 24VDC supply voltage, rated for 2.5A AC/DC operation at 125VAC or 30VDC. The device features a 102kgf holding force, cable lead termination, status indicator capability, and IP67 ingress protection suitable for dust-tight and waterproof applications.

The HS5E-B4405-G is designated as obsolete. Identifying equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for replacement, repair, and new installations where this legacy component is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HS5E-B4405-G is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: DPST-NO/NC + DPST-NC
• Current rating: 2.5A (AC/DC)
• Voltage rating: 125VAC, 30VDC
• Supply voltage: 24VDC
• Actuator type: Panel Disconnect
• Ingress protection: IP67
• RoHS compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Holding force: May increase (higher force provides equivalent or superior mechanical retention)
• Termination style: May differ (cable leads vs. spring terminal) provided mechanical and electrical interface compatibility is confirmed
• Operating temperature range: May extend (wider range maintains or exceeds original specification)
• Approval agencies: May expand (additional certifications do not reduce compliance)
• Product status: Active status preferred for long-term availability

The HS5L-VB44M-G meets all mandatory matching parameters and represents a direct functional equivalent with enhanced specifications in holding force and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The HS5L-VB44M-G is a direct functional substitute for the obsolete HS5E-B4405-G. Both components share identical circuit configuration, current and voltage ratings, supply voltage, actuator type, and ingress protection classification.

The HS5L-VB44M-G offers the following advantages:

• Active Product Status: Currently manufactured and supported by IDEC, ensuring long-term availability and supply chain continuity.
• Enhanced Holding Force: 143kgf vs. 102kgf provides superior mechanical retention without compromising electrical or thermal performance.
• Extended Operating Temperature Range: −25°C to +55°C vs. −25°C to +50°C accommodates wider environmental conditions.
• Expanded Certifications: Includes CCC and UL approvals in addition to CE and TUV, broadening regulatory compliance scope.
• ROHS3 Compliance: Maintains full RoHS3 compliance equivalent to the original part.

Termination Consideration: The HS5L-VB44M-G uses spring terminal termination instead of cable leads. Integration into existing harnesses or connector systems requires mechanical and electrical interface verification to confirm compatibility with the original cable lead configuration.

Frequently Asked Questions (FAQ)

Q: Can the HS5L-VB44M-G directly replace the HS5E-B4405-G without modification?

A: The HS5L-VB44M-G matches all critical electrical and functional parameters. However, the termination style differs (spring terminal vs. cable leads). Direct replacement requires confirmation that the spring terminal interface is compatible with the existing connector or harness assembly. Mechanical mounting and electrical connection points must be verified.

Q: Does the higher holding force of the HS5L-VB44M-G (143kgf vs. 102kgf) affect system operation?

A: No. The increased holding force is a specification enhancement that maintains or exceeds the mechanical retention capability of the original part. It does not alter electrical performance, switching characteristics, or response time. The higher force is compatible with all applications designed for the original 102kgf specification.

Q: Are there any compliance or certification differences between the two parts?

A: Both parts are ROHS3 compliant. The HS5L-VB44M-G carries additional certifications (CCC, UL) beyond the original part's CE, cURus, and TUV approvals. These additional certifications expand regulatory coverage and do not reduce compliance with the original specifications.

Q: What is the impact of the extended operating temperature range on the HS5L-VB44M-G?

A: The HS5L-VB44M-G operates from −25°C to +55°C, compared to −25°C to +50°C for the original part. This 5°C extension at the upper limit provides additional thermal margin and is fully backward compatible with applications designed for the original temperature range.

Q: Is the HS5L-VB44M-G available in the same packaging as the HS5E-B4405-G?

A: The HS5L-VB44M-G is supplied in bulk packaging. Original packaging specifications for the HS5E-B4405-G are not provided in the technical data. Packaging requirements should be confirmed with the supplier or procurement department.

Q: What is the inventory status of the HS5L-VB44M-G?

A: The HS5L-VB44M-G has 1,131 pieces in stock as new original inventory, compared to 982 pieces for the obsolete HS5E-B4405-G. The active product status and higher inventory level support reliable supply for current and future applications.
