Sensata-Crydom 84134111 SSR Relay SPST-NO 25A 48-660V Equivalent & Substitute Parts

Part Overview

The Sensata-Crydom 84134111 is a solid-state relay (SSR) with SPST-NO (1 Form A) configuration, rated for 25A load current and 48V to 660V output voltage range. This hockey puck-style chassis mount relay operates with AC zero-cross switching and accepts 90-280VAC input voltage. The component is active in production status and ROHS3 compliant. Equivalent and substitute parts are identified when they maintain identical or compatible electrical and mechanical specifications within the allowed parameter ranges for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 84134111 are qualified based on the following critical parameters that determine functional compatibility:

• Circuit Configuration: Must be SPST-NO (1 Form A)
• Load Current Rating: Must be 25 A
• Load Voltage Range: Must support 48 V ~ 660 V
• Output Type: Must be AC with zero-cross switching
• Package / Case: Must be Hockey Puck form factor
• Mounting Type: Must be Chassis Mount
• Termination Style: Must be Screw Terminal
• Input Voltage Range: Must accommodate the control signal voltage requirements

The substitute part 84137111N (Crouzet) meets these criteria with input voltage range of 20 ~ 265VAC, which overlaps with the main part's 90 ~ 280VAC specification within acceptable operating margins for this relay category.

Parameter Comparison

Engineering Selection Recommendations

Both the 84134111 (Sensata-Crydom) and 84137111N (Crouzet) are active production components with full compliance certifications. The 84134111 carries ROHS3 compliance status, while the 84137111N carries standard RoHS compliance. Both components are REACH-affected or REACH-unaffected respectively, reflecting their regulatory classification. Selection between these parts should be based on supply chain availability, packaging preference (Bulk vs. Box), and specific regulatory requirements of the end application. The input voltage range difference (90-280VAC vs. 20-265VAC) represents a minor specification variance that does not affect substitution eligibility within standard industrial relay applications.

Frequently Asked Questions (FAQ)

Q: Can the 84137111N (Crouzet) directly replace the 84134111 (Sensata-Crydom)?

A: Yes. Both parts share identical circuit configuration (SPST-NO), load current rating (25A), load voltage range (48-660V), output type (AC zero-cross), package form factor (hockey puck), and termination style (screw terminal). The input voltage ranges overlap sufficiently for standard applications.

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

A: The 84134111 accepts 90-280VAC input, while the 84137111N accepts 20-265VAC input. The overlapping range (90-265VAC) covers typical industrial control signal voltages. Applications operating strictly above 265VAC input would require the 84134111.

Q: Are there packaging differences between these parts?

A: Yes. The 84134111 is supplied in Bulk packaging, while the 84137111N is supplied in Box packaging. Both use identical hockey puck form factor and screw terminal configuration.

Q: What compliance certifications apply to each part?

A: The 84134111 is ROHS3 compliant and REACH affected. The 84137111N is RoHS compliant and REACH unaffected. Both carry EAR99 ECCN classification and are suitable for industrial relay applications.

Q: Are these parts interchangeable in existing designs?

A: Yes, provided the application input voltage remains within the 20-265VAC overlapping range. Mechanical mounting (chassis mount, screw terminal) and electrical ratings (25A, 48-660V load) are identical, enabling direct substitution in PCB layouts and control circuits.
