Ohmite 45J500 Equivalent & Substitute Parts

Part Overview

The Ohmite 45J500 is a 500 Ohm, 5W axial wirewound through-hole resistor from the Ohmicone® 40 series. This component is classified as Active and remains in production. Substitute parts are identified when the original part becomes unavailable, when alternative packaging options are required, or when compliance requirements necessitate updated component versions.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 45J500 are determined by matching the following critical electrical and mechanical parameters:

• Resistance value: 500 Ohms
• Tolerance: ±5%
• Power rating: 5W
• Composition: Wirewound
• Package configuration: Axial
• Temperature coefficient: ±20ppm/°C
• Physical dimensions: 0.343" Dia x 0.937" L (8.70mm x 23.80mm)
• Number of terminations: 2

The 45J500E meets all these criteria and is classified as a parametric equivalent. The primary distinction between these parts is packaging format and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 45J500 and 45J500E are electrically and mechanically identical components from the Ohmicone® 40 series. Selection between these parts is determined by compliance and packaging requirements:

The 45J500E is ROHS3 compliant, making it the appropriate choice for applications subject to RoHS regulations or where compliance documentation is required. The 45J500 is RoHS non-compliant and suitable for applications without RoHS mandates.

Packaging format differs between the two parts: the 45J500 is supplied in standard packaging, while the 45J500E is supplied in bulk packaging. Bulk packaging may be preferred for high-volume production environments.

Both parts carry identical REACH and ECCN classifications, indicating equivalent regulatory treatment for export and environmental compliance purposes.

Frequently Asked Questions (FAQ)

Q: Are the 45J500 and 45J500E electrically interchangeable?

A: Yes. Both parts have identical electrical specifications: 500 Ohm resistance, ±5% tolerance, 5W power rating, ±20ppm/°C temperature coefficient, and wirewound composition. They are direct functional equivalents.

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

A: The primary differences are RoHS compliance status and packaging format. The 45J500E is ROHS3 compliant and supplied in bulk packaging, while the 45J500 is RoHS non-compliant and supplied in standard packaging.

Q: Can I use the 45J500E as a replacement for the 45J500 in existing designs?

A: Yes, provided your application does not have specific packaging requirements. The electrical and mechanical specifications are identical, and the improved RoHS compliance of the 45J500E may be advantageous for future production runs.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.343" diameter by 0.937" length (8.70mm x 23.80mm) and use identical axial package configuration with two terminations.

Q: Which part should I specify for new designs?

A: Specify the 45J500E for new designs unless RoHS compliance is not a requirement. The ROHS3 compliance provides regulatory flexibility and future-proofs the design against evolving environmental standards.
