Ohmite 90J100 11W 100 Ohm Axial Wirewound Resistor - Equivalent & Substitute Parts

Part Overview

The Ohmite 90J100 is a 100 Ohm, 11W through-hole axial wirewound resistor with flame retardant coating and safety features. This component is classified as Active product status and is designed for applications requiring high power dissipation in a compact axial package. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, supply chain considerations, or compliance requirements.

Substitute Part Grouping Explanation

Substitute parts for the Ohmite 90J100 are qualified based on strict parametric equivalence across the following criteria:

• Resistance value: 100 Ohms
• Tolerance: ±5%
• Power rating: 11W
• Composition: Wirewound
• Package configuration: Axial
• Physical dimensions: 0.343" Dia x 1.811" L (8.70mm x 46.00mm)
• Temperature coefficient: ±30ppm/°C
• Termination count: 2

Parts meeting all these parameters are classified as direct parametric equivalents and may be substituted in applications where the original part number is unavailable.

Parameter Comparison

Engineering Selection Recommendations

Both the 90J100 and 90J100E are active product offerings from Ohmite with identical electrical and mechanical specifications. The primary distinction is regulatory compliance: the 90J100E carries ROHS3 compliance certification, while the 90J100 is RoHS non-compliant. Selection between these parts should be based on applicable regulatory requirements for the end application. Where ROHS3 compliance is mandated, the 90J100E is the appropriate selection. Both parts are suitable for direct substitution where compliance requirements are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the 90J100E replace the 90J100 in existing designs?

A: Yes. The 90J100E is a parametric equivalent with identical electrical characteristics (100 Ohms, ±5%, 11W), composition (wirewound), and physical dimensions (0.343" Dia x 1.811" L). Direct substitution is permissible from an electrical and mechanical standpoint. Verify compliance requirements for your application.

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

A: The 90J100E is ROHS3 compliant, while the 90J100 is RoHS non-compliant. All other specifications are identical.

Q: Are the axial package dimensions identical between both parts?

A: Yes. Both parts share identical dimensions of 0.343" Dia x 1.811" L (8.70mm x 46.00mm) and are compatible with the same PCB footprints and through-hole mounting configurations.

Q: What parameters must remain constant for substitution?

A: Resistance value (100 Ohms), tolerance (±5%), power rating (11W), composition (wirewound), package type (axial), and physical dimensions must all match for valid substitution.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Both parts share the same temperature coefficient of ±30ppm/°C. Substitution is valid for applications within the specified operating temperature range.
