HS5E-DD4403-G Equivalent & Substitute Parts

Part Overview

The HS5E-DD4403-G is an interlock solenoid release switch manufactured by IDEC, classified as a DPST-NC (Double Pole Single Throw - Normally Closed) configuration. This component functions as a panel disconnect actuator with a holding force of 102 kgf, designed for 24VDC supply operation with dual circuit capability rated at 2.5A (AC/DC). The part is currently obsolete, necessitating identification of functionally equivalent alternatives to maintain system continuity and support ongoing maintenance requirements.

Key Parameters

Substitute Part Grouping Explanation

The HS5L-DD44M-G qualifies as a functional substitute based on the following critical parameters:

Electrical Compatibility:

• Identical circuit configuration (DPST-NC x 2)
• Matching current rating (2.5A AC/DC)
• Identical voltage rating (125VAC, 30VDC)
• Identical supply voltage (24VDC)

Mechanical Compatibility:

• Same actuator type (Panel Disconnect)
• Same solenoid release function
• Enhanced holding force (143 kgf vs. 102 kgf) provides superior performance margin
• Extended operating temperature range (-25°C to 55°C vs. -25°C to 50°C)

Environmental & Compliance:

• Identical ingress protection rating (IP67)
• ROHS3 compliant
• Enhanced approval certifications (CCC, CE, TUV, UL vs. CE, cURus, TUV)

Operational Differences:

• Termination style differs (Spring Terminal vs. Cable Leads) - requires connector adaptation
• Conduit thread size specified (M20) for the substitute
• Product status is Active, ensuring ongoing availability

Engineering Selection Recommendations

The HS5L-DD44M-G is the designated substitute for the obsolete HS5E-DD4403-G. Selection is based on:

Electrical Equivalence: All critical electrical parameters are identical, ensuring direct functional replacement in 24VDC solenoid release applications with DPST-NC switching requirements.

Compliance & Certification: The substitute carries expanded approval certifications (CCC, CE, TUV, UL) compared to the original part (CE, cURus, TUV), providing enhanced regulatory coverage. Both parts maintain ROHS3 compliance.

Active Product Status: The HS5L-DD44M-G is currently in active production with confirmed inventory availability (1053 pcs), ensuring long-term supply continuity and technical support.

Performance Enhancement: The increased holding force (143 kgf vs. 102 kgf) and extended temperature range (-25°C to 55°C vs. -25°C to 50°C) provide operational margin improvements over the original specification.

Integration Consideration: Termination style transition from Cable Leads to Spring Terminal requires connector interface modification during installation.

Frequently Asked Questions (FAQ)

Q: Can the HS5L-DD44M-G directly replace the HS5E-DD4403-G without circuit modification?

A: Electrical and functional replacement is direct. The DPST-NC x 2 circuit configuration, current rating (2.5A AC/DC), voltage rating (125VAC, 30VDC), and 24VDC supply voltage are identical. Physical installation requires connector adaptation due to termination style change from Cable Leads to Spring Terminal.

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

A: The HS5L-DD44M-G provides 143 kgf holding force compared to 102 kgf in the original part. This represents a 40% increase in mechanical holding capacity, providing enhanced performance margin for panel disconnect applications without exceeding the original design envelope.

Q: Are there compliance differences between the two parts?

A: Both parts are ROHS3 compliant. The substitute carries additional certifications (CCC, UL) beyond the original part's certifications (CE, cURus, TUV). Both maintain CE and TUV approval. The expanded certification profile of the substitute supports broader regulatory requirements.

Q: Does the operating temperature range difference affect substitution suitability?

A: The substitute operates across -25°C to 55°C versus the original -25°C to 50°C. This 5°C upper temperature extension provides additional thermal margin. For applications within the original -25°C to 50°C range, the substitute performs equivalently or better.

Q: What connector modifications are required for the termination style change?

A: The original part uses Cable Leads termination; the substitute uses Spring Terminal termination. Installation requires appropriate connector interfaces compatible with Spring Terminal configuration. Electrical continuity and current-carrying capacity must be maintained at 2.5A (AC/DC).

Q: Is the M20 conduit thread size on the substitute a mandatory requirement?

A: The M20 conduit thread size is specified for the substitute part. This parameter should be evaluated against the original installation environment. If the original installation does not require conduit threading, this specification does not impact substitution feasibility.
