H12WD48110-10 Equivalent & Substitute Parts

Part Overview

The H12WD48110-10 is a solid state relay (SSR) manufactured by Sensata-Crydom, configured as a SPST-NO (1 Form A) device in a hockey puck package. This component is rated for 110A load current with an AC output and operates with a 4–32VDC input signal across a 48–660V load voltage range. The product is currently obsolete, making identification of suitable substitute components essential for system maintenance, repair, and redesign applications where this relay is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the H12WD48110-10 is determined by the following critical parameters:

• Circuit configuration (SPST-NO / 1 Form A)
• Package type (Hockey Puck)
• Mounting method (Chassis Mount)
• Termination style (Screw Terminal)
• Input voltage range (4 ~ 32VDC)
• Output type (AC)
• Load voltage range compatibility (minimum 48V, maximum 660V or higher)
• Load current capacity (minimum 110A)

Substitute parts must maintain compatibility across all these parameters. Load current capacity may exceed the original specification, provided all other electrical and mechanical characteristics align with the original design requirements.

Parameter Comparison

Engineering Selection Recommendations

H12WD48125-10 (Sensata-Crydom): This part is the direct manufacturer upgrade within the H12WD series. It maintains identical electrical and mechanical specifications to the H12WD48110-10 while offering increased load current capacity (125A vs. 110A). The part is active and RoHS compliant, making it the preferred choice for direct replacement in applications where the original specification is maintained or where the additional current capacity provides operational margin.

84138180N (Crouzet): This part provides functional equivalence with the same circuit configuration, input voltage range, load current capacity (125A), and hockey puck package. However, the maximum load voltage is 500V, which is lower than the original 660V specification. This part is suitable only for applications where the load voltage does not exceed 500V. The part is active and RoHS compliant. The addition of zero-cross switching capability may provide benefits in certain AC load applications.

Frequently Asked Questions (FAQ)

Q: Can the H12WD48125-10 be used as a direct replacement for the H12WD48110-10?

A: Yes. The H12WD48125-10 maintains all electrical and mechanical parameters of the original part while providing increased load current capacity. No design modifications are required.

Q: What is the key limitation of the 84138180N substitute?

A: The 84138180N has a maximum load voltage rating of 500V, compared to the original 660V specification. It is suitable only for applications operating at or below 500V load voltage.

Q: Are all substitute parts compatible with the same mounting and termination hardware?

A: Yes. All substitute parts use hockey puck packaging with chassis mount configuration and screw terminal termination, ensuring mechanical and electrical interface compatibility.

Q: Does the zero-cross switching feature of the 84138180N affect compatibility?

A: Zero-cross switching is an additional feature that does not prevent substitution. It may improve performance in certain AC load applications but is not required for basic functional equivalence.

Q: What compliance certifications apply to the substitute parts?

A: The H12WD48125-10 is RoHS compliant. The 84138180N is RoHS compliant. Both parts are REACH unaffected and classified as EAR99 for export control purposes.
