Key Parameters

Substitute Part Grouping Explanation

The HS5L-VA44M-G qualifies as a functional substitute for the HS5E-A4403-G based on the following critical parameters:

Matching Parameters (Substitution Basis):

• Manufacturer: IDEC (same manufacturer ensures design compatibility)
• Type: Solenoid Release (identical functional classification)
• Circuit Configuration: DPST-NO/NC x 2 (identical electrical circuit)
• Current Rating: 2.5A (AC/DC) (identical current capacity)
• Voltage Rating: 125VAC, 30VDC (identical voltage specifications)
• Supply Voltage: 24VDC (identical operating voltage)
• Actuator Type: Panel Disconnect (identical mechanical interface)
• Ingress Protection: IP67 - Dust Tight, Waterproof (identical environmental protection)
• RoHS Status: ROHS3 Compliant (equivalent regulatory compliance)

Differing Parameters (Functional Enhancements):

• Holding Force: 143kgf (substitute provides 41kgf increase)
• Termination Style: Spring Terminal (substitute uses spring terminal vs. cable leads)
• Operating Temperature Range: -25°C ~ 55°C (substitute extends upper limit by 5°C)
• Approval Agencies: CCC, CE, TUV, UL (substitute includes additional UL and CCC certifications)
• Product Status: Active (substitute is currently in production)

The HS5L-VA44M-G represents an active production alternative within the IDEC interlock solenoid release product line, offering enhanced holding force and extended temperature range while maintaining electrical and mechanical compatibility.

Engineering Selection Recommendations

The HS5L-VA44M-G is the designated substitute for the obsolete HS5E-A4403-G. Selection of the HS5L-VA44M-G is supported by:

Product Status: The HS5L-VA44M-G maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete HS5E-A4403-G.

Regulatory Compliance: Both components meet ROHS3 compliance requirements. The HS5L-VA44M-G carries expanded approval certifications (CCC, CE, TUV, UL) compared to the original part (CE, cURus, TUV), providing broader market acceptance and regulatory coverage.

Electrical Compatibility: Identical circuit configuration (DPST-NO/NC x 2), current rating (2.5A AC/DC), voltage rating (125VAC, 30VDC), and supply voltage (24VDC) ensure direct functional equivalence in electrical applications.

Mechanical Compatibility: Both components feature identical panel disconnect actuator type and IP67 ingress protection, maintaining environmental sealing and mechanical interface requirements.

Performance Enhancement: The HS5L-VA44M-G provides increased holding force (143kgf vs. 102kgf) and extended operating temperature range (-25°C ~ 55°C vs. -25°C ~ 50°C), offering improved performance margins in demanding applications.

Termination Consideration: The HS5L-VA44M-G uses spring terminal termination versus cable leads on the original part. Installation procedures and wiring harness design must accommodate this termination style difference.

Frequently Asked Questions (FAQ)

Q: Can the HS5L-VA44M-G directly replace the HS5E-A4403-G in existing installations?

A: The HS5L-VA44M-G provides electrical and mechanical compatibility for direct substitution. The primary consideration is termination style: the substitute uses spring terminal connections instead of cable leads. Wiring harness and connection methodology must be adapted accordingly.

Q: What are the key electrical parameters that make these parts interchangeable?

A: Both components share identical circuit configuration (DPST-NO/NC x 2), current rating (2.5A AC/DC), voltage rating (125VAC, 30VDC), and supply voltage (24VDC). These parameters define functional equivalence for electrical circuit applications.

Q: Does the increased holding force of the HS5L-VA44M-G (143kgf vs. 102kgf) affect compatibility?

A: The increased holding force represents a performance enhancement and does not compromise compatibility. Applications requiring the original 102kgf specification will function correctly with the higher-force substitute. Applications with mechanical load requirements between 102kgf and 143kgf benefit from the enhanced performance margin.

Q: Are there regulatory or certification differences between these parts?

A: Both components are ROHS3 compliant. The HS5L-VA44M-G carries additional certifications (CCC, UL) beyond the original part's certifications (CE, cURus, TUV). These additional certifications expand market applicability without reducing compatibility.

Q: What is the impact of the extended operating temperature range on the HS5L-VA44M-G?

A: The HS5L-VA44M-G extends the upper operating temperature limit from 50°C to 55°C. This enhancement provides additional thermal margin and does not affect compatibility with applications operating within the original temperature range (-25°C ~ 50°C).

Q: How does the termination style difference affect installation?

A: The HS5E-A4403-G uses cable lead termination, while the HS5L-VA44M-G uses spring terminal termination. Installation procedures, wiring harness design, and connection methodology must be adapted to accommodate spring terminal connections. Mechanical mounting and panel interface remain compatible.

Q: Is the HS5L-VA44M-G suitable for applications with environmental sealing requirements?

A: Yes. Both components maintain IP67 ingress protection (dust tight, waterproof), ensuring equivalent environmental sealing performance for applications requiring protection against dust and water ingress.
