HS5E-B4403-G Equivalent & Substitute Parts

Part Overview

The HS5E-B4403-G is an interlock solenoid release switch manufactured by IDEC, designed for panel disconnect applications with dual-pole switching capability. This component operates at 24VDC supply voltage and provides 2.5A switching capacity across both AC and DC circuits. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HS5E-B4403-G is determined by strict equivalence across the following critical 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 rating (IP67)
• Operating temperature range compatibility
• Regulatory compliance (CE, TUV certifications)

The HS5L-VB44M-G meets all mandatory electrical and mechanical substitution criteria. Both components share identical circuit topology, current capacity, voltage specifications, and environmental protection ratings. Differences in holding force, termination style, and operating temperature upper limit represent design variations within the same functional category and do not preclude substitution where the application requirements fall within the specified parameters of both components.

Parameter Comparison

Engineering Selection Recommendations

The HS5L-VB44M-G is the designated equivalent substitute for the obsolete HS5E-B4403-G. Selection of the substitute component is justified on the following basis:

• Both components maintain identical electrical specifications across all critical switching parameters
• The substitute part carries active product status, ensuring ongoing availability and supply chain continuity
• Regulatory compliance is enhanced in the substitute, which includes UL certification in addition to CE and TUV approvals held by the original part
• ROHS3 compliance is maintained across both components
• The substitute component operates across an extended temperature range (-25°C to 55°C versus -25°C to 50°C), providing broader environmental tolerance
• Increased holding force in the substitute (143kgf versus 102kgf) represents a design improvement that does not compromise backward compatibility

Termination style differs between the two components (cable leads versus spring terminal). Installation procedures must account for this mechanical difference during component replacement.

Frequently Asked Questions (FAQ)

Q: Can the HS5L-VB44M-G directly replace the HS5E-B4403-G in existing installations?

A: Yes, provided that the mechanical mounting interface accommodates the spring terminal configuration of the substitute part. The electrical specifications are fully equivalent.

Q: What is the significance of the increased holding force in the substitute part?

A: The HS5L-VB44M-G provides 143kgf holding force compared to 102kgf in the original part. This represents a design enhancement and does not create incompatibility. Applications requiring the original holding force specification will continue to function correctly with the substitute.

Q: Are there differences in regulatory compliance between the two parts?

A: The substitute part includes UL certification in addition to CE and TUV approvals. Both components are ROHS3 compliant. The expanded certification profile of the substitute part does not affect substitution eligibility.

Q: How does the operating temperature range difference affect substitution?

A: The substitute part operates to 55°C versus 50°C for the original part. This extended upper temperature limit provides additional margin and does not restrict substitution in applications within the original part's temperature specification.

Q: What installation considerations apply to the termination style change?

A: The original part uses cable leads while the substitute uses spring terminals. Wiring connections must be adapted accordingly during installation. Consult component datasheets for specific terminal specifications and connection procedures.
