Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Sensata-Crydom 84134910 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A)
• Load Current Rating: Must be 25A minimum
• Load Voltage Range: Must support 24V to 280V AC
• Input Voltage Range: Must accommodate 3V to 32VDC or compatible subset
• Mounting Type: Must be Chassis Mount
• Termination Style: Must be Screw Terminal
• Package Format: Must be Hockey Puck

The substitute part 84137910N from Crouzet meets these core electrical and mechanical requirements, enabling direct functional replacement in applications requiring SPST-NO solid-state relay performance at 25A load current.

Parameter Comparison

Engineering Selection Recommendations

84134910 (Sensata-Crydom): Primary selection for applications requiring ROHS3 compliance. Active product status ensures continued availability and support. REACH Affected status requires compliance verification in regulated markets.

84137910N (Crouzet): Qualified substitute offering RoHS compliance with zero-cross output type feature. Input voltage range begins at 4VDC (versus 3VDC minimum for primary part). REACH Unaffected status may provide advantages in certain regulatory jurisdictions. Active product status confirms ongoing manufacturability.

Both parts satisfy identical load current (25A), load voltage (24V–280V AC), mounting configuration (Chassis Mount), and package format (Hockey Puck) requirements. Selection between these parts should be based on specific compliance requirements, input voltage floor specifications, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can 84137910N replace 84134910 in all applications?

A: The 84137910N meets the core electrical and mechanical specifications for SPST-NO 25A AC relay operation at 24V–280V load voltage. The primary difference is the input voltage minimum of 4VDC versus 3VDC. Applications operating below 4VDC input require the original 84134910 part.

Q: What is the significance of "Zero Cross" output type in the substitute part?

A: Zero-cross functionality in the 84137910N provides switching at AC voltage zero-crossing points, which may reduce electromagnetic interference and improve load switching characteristics in certain applications. This is an additional feature not specified in the primary part.

Q: Are both parts physically interchangeable?

A: Yes. Both parts share identical mounting type (Chassis Mount), termination style (Screw Terminal), and package format (Hockey Puck), enabling direct physical installation without mechanical modification.

Q: What compliance differences exist between these parts?

A: The 84134910 is ROHS3 Compliant and REACH Affected. The 84137910N is RoHS Compliant and REACH Unaffected. Applications in regulated markets should verify compliance requirements before substitution.

Q: Are there inventory considerations for these parts?

A: The 84134910 has 636 pieces in stock (Bulk packaging). The 84137910N has 660 pieces in stock (Box packaging). Packaging format differences may affect procurement and handling procedures.
