H10D4850 Solid State Relay SPST-NO 50A 48-530V Equivalent & Substitute Parts

Part Overview

The H10D4850 is a Solid State Relay (SSR) with SPST-NO (1 Form A) configuration manufactured by Sensata-Crydom. This hockey puck-style relay is rated for 50A load current with input voltage range of 4-32VDC and output voltage range of 48-530V AC with zero-cross switching. The H10D4850 is classified as obsolete, making identification of equivalent and substitute parts essential for system maintenance, repair, and new design implementations where this component is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the H10D4850 is determined by electrical and mechanical compatibility across the following parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A)
• Output Type: Must be AC with zero-cross switching
• Input Voltage Range: Must accommodate 4-32VDC
• Load Current Rating: Must be rated for 50A minimum
• Load Voltage Range: Must support at least 48V minimum; higher maximum voltage ratings are acceptable
• Mounting Type: Must be chassis mount
• Termination Style: Must use screw terminals
• Package Type: Must be hockey puck form factor

Two substitute parts meet these criteria: the H12WD4850 (Sensata-Crydom, active product status) and the SSR-480D50 (TE Connectivity Potter & Brumfield Relays, active product status). Both substitutes maintain electrical equivalence while offering extended load voltage ratings and active product support.

Parameter Comparison

Engineering Selection Recommendations

H12WD4850 (Sensata-Crydom): This substitute maintains the same manufacturer lineage as the original H10D4850 and is classified as active product status. The H12WD4850 extends the maximum load voltage rating from 530V to 660V while maintaining all other electrical and mechanical specifications. This part is ROHS3 compliant and REACH affected. Selection of this substitute provides continuity with the original manufacturer while ensuring ongoing product support and availability.

SSR-480D50 (TE Connectivity Potter & Brumfield Relays): This substitute is manufactured by TE Connectivity and is classified as active product status. The SSR-480D50 matches all electrical specifications of the H10D4850 and extends the maximum load voltage rating to 660V. This part is ROHS3 compliant, REACH affected, and carries MSL rating of 1 (Unlimited). Selection of this substitute provides access to an alternative manufacturer with established product support.

Both substitutes are electrically and mechanically compatible with the H10D4850 and are suitable for direct replacement in applications where the original part is specified.

Frequently Asked Questions (FAQ)

Q: Can the H12WD4850 be used as a direct replacement for the H10D4850?

A: Yes. The H12WD4850 maintains identical electrical specifications for input voltage (4-32VDC), load current (50A), circuit configuration (SPST-NO), output type (AC, zero cross), mounting type (chassis mount), termination style (screw terminal), and package type (hockey puck). The H12WD4850 extends the maximum load voltage rating to 660V, which is compatible with applications designed for the H10D4850's 530V maximum rating.

Q: Can the SSR-480D50 be used as a direct replacement for the H10D4850?

A: Yes. The SSR-480D50 maintains identical electrical specifications for input voltage (4-32VDC), load current (50A), circuit configuration (SPST-NO), output type (AC, zero cross), mounting type (chassis mount), termination style (screw terminal), and package type (hockey puck). The SSR-480D50 extends the maximum load voltage rating to 660V, which is compatible with applications designed for the H10D4850's 530V maximum rating.

Q: What is the primary difference between the H10D4850 and its substitutes?

A: The H10D4850 is classified as obsolete, while both the H12WD4850 and SSR-480D50 are active products. Both substitutes extend the maximum load voltage rating from 530V to 660V. All three parts share identical input voltage, load current, circuit configuration, output type, mounting type, termination style, and package type specifications.

Q: Are there any compliance differences between the substitute parts?

A: The H12WD4850 is ROHS3 compliant and REACH affected. The SSR-480D50 is ROHS3 compliant, REACH affected, and carries an MSL rating of 1 (Unlimited). Both substitutes meet current regulatory requirements for electronic components.

Q: What mounting and termination considerations apply to these parts?

A: All three parts (H10D4850, H12WD4850, and SSR-480D50) are chassis mount relays with screw terminal connections in hockey puck form factor. No mechanical modifications are required for substitution.
