SSR Relay SPST-NO 84134142 Equivalent & Substitute Parts

Part Overview

The Sensata-Crydom 84134142 is an active solid-state relay (SSR) with SPST-NO (1 Form A) configuration, rated for 100A load current at 48–660V output. This hockey puck-style chassis mount relay features AC zero-cross switching and screw terminal connections, designed for high-current AC switching applications. The part is RoHS compliant and carries unlimited moisture sensitivity rating (MSL 1). Finding equivalent or substitute parts may be necessary due to inventory constraints, lead time requirements, or application-specific compatibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 84134142 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain functional equivalence
• Package / Case: Must be Hockey Puck to ensure mechanical compatibility with existing mounting
• Mounting Type: Must be Chassis Mount for installation compatibility
• Termination Style: Must be Screw Terminal for connection compatibility
• Output Type: Must be AC with Zero Cross switching for application compatibility
• Load Current Rating: Substitute must meet or exceed 100A requirement
• Load Voltage Range: Substitute must cover the 48–660V operating window
• Input Voltage: Substitute input voltage must be compatible with control circuit requirements
• RoHS Compliance: Must maintain RoHS compliance status for regulatory alignment

The substitute part 84138153N (Crouzet GN+ series) meets these criteria with the following considerations: it maintains identical circuit configuration, package type, mounting style, and termination method. However, the load current rating is 90A (below the 100A specification) and the load voltage range is 24–500V (narrower than 48–660V). The input voltage range is 20–260VAC/DC, which overlaps with but extends beyond the original 18–36VAC specification.

Parameter Comparison

Engineering Selection Recommendations

Both the 84134142 and 84138153N are active products with RoHS compliance and REACH unaffected status, ensuring regulatory alignment for current applications. The primary distinction lies in electrical performance specifications: the 84134142 provides higher load current capacity (100A vs. 90A) and broader load voltage coverage (48–660V vs. 24–500V). Selection between these parts should be based on whether the application load current and voltage requirements fall within the narrower specifications of the 84138153N. If the application requires the full 100A capacity or operates at voltages exceeding 500V, the 84134142 is the appropriate choice. If application requirements are within the 90A and 24–500V envelope, the 84138153N provides functional equivalence with identical mechanical and control interface characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 84138153N directly replace the 84134142 in all applications?

A: Direct replacement is limited by electrical specifications. The 84138153N is suitable only for applications where load current does not exceed 90A and load voltage remains within 24–500V. Applications requiring the full 100A capacity or higher voltage operation require the 84134142.

Q: Are the mechanical interfaces identical between these parts?

A: Yes. Both parts share identical package type (Hockey Puck), mounting method (Chassis Mount), and termination style (Screw Terminal), ensuring mechanical and connection compatibility.

Q: What is the significance of the input voltage difference?

A: The 84134142 accepts 18–36VAC input, while the 84138153N accepts 20–260VAC/DC. The 84138153N's broader input range provides greater flexibility for control circuit integration, though both are compatible with standard 24VAC control signals.

Q: Do both parts support zero-cross switching?

A: Yes. Both the 84134142 and 84138153N feature AC zero-cross output switching, providing identical switching characteristics for AC load control.

Q: Are there compliance or certification differences?

A: Both parts are RoHS compliant and active products. The 84138153N carries additional REACH unaffected status documentation. Both carry ECCN EAR99 classification.
