Parameter Comparison

Engineering Selection Recommendations

Both the primary part (84134320) and substitute part (84137320N) are active products with RoHS compliance certification. Selection between these parts should be based on:

• Availability: Choose based on current inventory status and supplier lead times
• Compliance Requirements: Both parts meet RoHS compliance standards for regulated applications
• Supply Chain Strategy: Maintain dual-source qualification to mitigate supply disruption risk
• Packaging Format: Both parts are supplied in hockey puck chassis mount configuration with screw terminals, ensuring mechanical and electrical compatibility in existing designs

Frequently Asked Questions (FAQ)

Q: Can 84137320N be used as a direct replacement for 84134320? A: Yes. Both parts share identical electrical specifications (SPST-NO circuit, 50A at 48-660V AC output, 4-32VDC input), mechanical configuration (chassis mount, screw terminal, hockey puck package), and compliance status (RoHS compliant, active product status).

Q: Are there differences in packaging between these parts? A: The primary part (84134320) is supplied in bulk packaging, while the substitute (84137320N) is supplied in box packaging. Both contain the same component in the hockey puck case format suitable for chassis mount applications.

Q: What parameters must remain identical for substitution? A: Load current (50A), load voltage range (48-660V AC), input voltage range (4-32VDC), circuit type (SPST-NO), output type (AC), mounting configuration (chassis mount), and termination style (screw terminal) must all match for functional equivalence.

Q: Are both parts suitable for industrial control applications? A: Both parts are active products with RoHS compliance, meeting industrial relay requirements. Selection depends on application-specific compliance certifications and supply availability.
