H12D4890-10 Equivalent & Substitute Parts

Part Overview

The H12D4890-10 is a solid-state relay (SSR) manufactured by Sensata Technologies, configured as a single-pole single-throw normally open (SPST-NO) device rated for 90A load current with an input voltage range of 4–32VDC and output voltage range of 48–530V AC. The device features a hockey puck form factor with screw terminal connections and is designed for chassis mount applications.

This part is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain system functionality and ensure continued availability for replacement and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the H12D4890-10 is determined by the following critical parameters:

• Circuit configuration (SPST-NO)
• Output type (AC)
• Input voltage range (4–32VDC)
• Load voltage range (minimum 48V, maximum ≥530V)
• Load current rating (≥90A)
• Mounting type (Chassis Mount)
• Package form factor (Hockey Puck)
• Termination style (Screw Terminal)

Two substitute parts meet these criteria and are identified as direct equivalents or functional upgrades:

1. CWD4890-10 (Sensata-Crydom): Direct equivalent with extended load voltage range (48–660V) and active product status
2. 84134340 (Sensata-Crydom): Manufacturer-recommended upgrade with increased load current rating (100A) and active product status

Parameter Comparison

Engineering Selection Recommendations

CWD4890-10 is the direct functional equivalent to the H12D4890-10. Both devices maintain identical input voltage, load current rating, circuit configuration, and physical form factor. The CWD4890-10 provides an extended load voltage range (48–660V versus 48–530V) and carries active product status with RoHS compliance, making it the primary substitute for direct replacement applications.

84134340 is the manufacturer-recommended upgrade option. This part increases the load current rating to 100A while maintaining all other critical parameters. The extended current capacity provides additional design margin and is suitable for applications where the original 90A rating is marginal or where future capacity expansion is anticipated. This part also carries active product status and RoHS compliance.

Both substitute parts are manufactured by Sensata-Crydom, a division of Sensata Technologies, ensuring compatibility with the original design ecosystem and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can CWD4890-10 be used as a direct replacement for H12D4890-10?

A: Yes. The CWD4890-10 maintains identical electrical specifications for input voltage (4–32VDC), load current (90A), circuit configuration (SPST-NO), and physical form factor (hockey puck, screw terminal, chassis mount). The extended load voltage range (48–660V) is backward compatible with the original 48–530V specification.

Q: What is the difference between CWD4890-10 and 84134340?

A: Both are active substitutes with identical input voltage and load voltage ranges. The primary difference is load current rating: CWD4890-10 is rated for 90A (matching the original), while 84134340 is rated for 100A. The 84134340 is the manufacturer-recommended upgrade for applications requiring additional current capacity.

Q: Are the substitute parts physically compatible with the original mounting?

A: Yes. Both CWD4890-10 and 84134340 maintain the hockey puck form factor, chassis mount configuration, and screw terminal termination style of the H12D4890-10, ensuring mechanical compatibility with existing installations.

Q: What compliance certifications apply to the substitute parts?

A: Both CWD4890-10 and 84134340 are RoHS compliant. Both carry ECCN classification EAR99 and HTSUS code 8536.49.0080 (CWD4890-10) or 8536.41.0060 (84134340), consistent with regulatory requirements for solid-state relay devices.

Q: Why is the H12D4890-10 classified as obsolete?

A: The H12D4890-10 has reached end-of-life status. Active alternatives from the same manufacturer family (Sensata-Crydom) are available with equivalent or enhanced specifications and current product support.
