Key Parameters

Substitute Part Grouping Explanation

The 90J500E qualifies as a parametric equivalent based on the following criteria:

• Identical resistance value: 500 Ohms
• Matching tolerance: ±5%
• Identical power rating: 11W
• Same composition: Wirewound
• Identical package type: Axial
• Matching physical dimensions: 0.343" Dia x 1.811" L (8.70mm x 46.00mm)
• Identical temperature coefficient: ±30ppm/°C
• Same features: Flame Retardant Coating, Safety
• Identical number of terminations: 2

The primary difference is packaging format (Bulk for 90J500E versus standard for 90J500) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 90J500 and 90J500E are active production parts from Ohmite with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory requirements:

• Use 90J500 for applications where RoHS non-compliance is acceptable or required by design specifications.
• Use 90J500E for applications requiring ROHS3 compliance or when sourcing from bulk packaging is preferred.

Both parts are suitable for direct substitution in circuits requiring 500 Ohm, 11W wirewound axial resistors with flame retardant coating.

Frequently Asked Questions (FAQ)

Q: Can 90J500E replace 90J500 in existing designs?

A: Yes. The 90J500E is electrically and mechanically identical to the 90J500. The primary difference is RoHS compliance status and packaging format. Substitution is valid for all applications where the original part was specified.

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

A: The 90J500E designation indicates ROHS3 compliance and bulk packaging, while the 90J500 is RoHS non-compliant with standard packaging. All electrical parameters, physical dimensions, and performance characteristics are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.343" diameter by 1.811" length (8.70mm x 46.00mm) and use the same axial package configuration. PCB layout and mounting considerations are identical.

Q: Does RoHS compliance affect performance?

A: No. RoHS compliance status reflects material composition and manufacturing process but does not alter electrical performance, power rating, tolerance, or temperature coefficient specifications.

Q: Can these parts be used interchangeably in production?

A: Yes, provided that the design and regulatory requirements of the end application are satisfied by the selected part's RoHS status.
