Sensata-Crydom 84140801H Solid State Relay - Equivalent & Substitute Parts

Part Overview

The Sensata-Crydom 84140801H is an active, production solid state relay (SSR) with SPST-NO (1 Form A) x 2 configuration in Hockey Puck package. This component is designed for AC load switching applications requiring 25A capacity at 24-280V output voltage range with 4-15VDC input control. The part is RoHS Compliant and carries MSL 1 (Unlimited) moisture sensitivity rating.

Substitute parts are identified when equivalent electrical performance can be achieved within the allowed parameter ranges for this SSR category, accounting for differences in load current capacity, voltage ratings, input control ranges, and package/termination styles.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 84140801H is determined by the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Circuit configuration: SPST-NO (1 Form A) x 2 (mandatory match)
• Output type: AC (mandatory match)
• Load current capacity: Equal to or greater than 25A
• Load voltage range: Must encompass or exceed 24-280V operating window
• Input control voltage: Must be compatible with 4-15VDC range
• Product status: Active production status required
• Compliance: RoHS or equivalent environmental compliance

Secondary Considerations:

• Package type and termination style may differ if mechanical integration is feasible
• Moisture sensitivity level MSL 1 is maintained across qualified substitutes

The substitute part 84140631N meets these criteria with enhanced electrical ratings (50A load current, 24-510V load voltage range, 4-32VDC input range) while maintaining identical circuit topology and AC output type.

Parameter Comparison

Engineering Selection Recommendations

84140801H Selection Criteria:

• Required load current: 25A or less
• Load voltage range: 24-280V
• Input control voltage: 4-15VDC
• Hockey Puck package form factor required
• Quick Connect termination preferred
• RoHS Compliant status required

84140631N Selection Criteria:

• Required load current: Up to 50A
• Load voltage range: 24-510V (extended range)
• Input control voltage: 4-32VDC (extended range)
• Module package form factor acceptable
• Screw Terminal termination acceptable
• ROHS3 Compliant status acceptable
• REACH Unaffected status applicable

Both parts maintain active production status and MSL 1 rating. The 84140631N provides enhanced electrical performance headroom with higher current and voltage ratings. Selection between these parts depends on specific application load requirements, available control voltage, and mechanical packaging constraints.

Frequently Asked Questions (FAQ)

Q: Can 84140631N directly replace 84140801H in all applications?

A: Electrical compatibility exists for applications within the 84140801H's rated parameters (25A maximum, 24-280V load range, 4-15VDC input). The 84140631N's higher ratings (50A, 24-510V, 4-32VDC) provide operational margin. However, package differences (Hockey Puck vs. Module) and termination style differences (Quick Connect vs. Screw Terminal) require mechanical integration verification.

Q: What are the key electrical differences between these parts?

A: The 84140631N provides higher load current capacity (50A vs. 25A), extended load voltage range (24-510V vs. 24-280V), and wider input control voltage range (4-32VDC vs. 4-15VDC). Both maintain identical SPST-NO (1 Form A) x 2 circuit topology and AC output type.

Q: Are there compliance differences between these parts?

A: Both parts carry MSL 1 (Unlimited) rating. The 84140801H is RoHS Compliant; the 84140631N is ROHS3 Compliant. The 84140631N additionally carries REACH Unaffected status. Both are EAR99 classified.

Q: What packaging differences exist?

A: The 84140801H uses Hockey Puck package with Quick Connect - 0.250" (6.3mm) termination. The 84140631N uses Module package with Screw Terminal termination. These differences affect mechanical mounting and electrical connection methods.

Q: Can I use 84140801H in an application designed for 84140631N?

A: No. The 84140801H has lower electrical ratings (25A vs. 50A load current, 280V vs. 510V maximum load voltage). Use only if application requirements fall within 84140801H specifications.
