Substitute Part Grouping Explanation

Substitution eligibility for the 84137320 is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST-NO (1 Form A)
• Output type: AC
• Input voltage range: 4 ~ 32VDC
• Load voltage range: 48 V ~ 660 V
• Load current rating: 50 A
• Mounting type: Chassis Mount
• Package type: Hockey Puck
• Termination style: Screw Terminal
• Series designation: GN

The substitute part 84137320N meets all electrical and mechanical requirements for direct substitution. Differences in packaging format (Bulk vs. Box), manufacturer (Sensata-Crydom vs. Crouzet), and regional compliance certifications do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both 84137320 and 84137320N are active production parts with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Packaging requirements: Choose 84137320 for bulk packaging or 84137320N for box packaging
• Regulatory jurisdiction: The 84137320 is REACH Affected; the 84137320N is REACH Unaffected. Applications subject to REACH regulations should specify 84137320N
• RoHS compliance level: Both parts are RoHS compliant; 84137320 meets ROHS3 while 84137320N meets general RoHS requirements
• Inventory availability: 84137320N currently has higher stock levels (933 units vs. 697 units)

Frequently Asked Questions (FAQ)

Q: Can 84137320N be used as a direct replacement for 84137320?

A: Yes. Both parts are electrically and mechanically equivalent with identical SPST-NO circuit configuration, 50A load current rating, 4-32VDC input voltage, and 48-660V AC output voltage range. Both use hockey puck packaging with screw terminals and chassis mounting.

Q: What is the difference between these two part numbers?

A: The primary differences are manufacturer (Sensata-Crydom vs. Crouzet), packaging format (Bulk vs. Box), and regional compliance certifications (REACH Affected vs. REACH Unaffected). Electrical performance and mechanical form factor are identical.

Q: Does packaging format affect compatibility?

A: No. Packaging format (Bulk vs. Box) does not affect electrical or mechanical compatibility. Selection should be based on procurement and storage requirements.

Q: Are both parts suitable for high-voltage AC applications?

A: Yes. Both 84137320 and 84137320N are rated for load voltages from 48V to 660V AC, making them suitable for industrial and utility-scale AC switching applications.

Q: What is the REACH compliance difference?

A: The 84137320 is REACH Affected, indicating it may contain substances of concern under REACH regulations. The 84137320N is REACH Unaffected. Applications in REACH-regulated regions should specify 84137320N.
