Ohmite 90J180 11W 180 Ohms Wirewound Resistor - Equivalent & Substitute Parts

Part Overview

The Ohmite 90J180 is an 11W, 180 Ohms wirewound resistor with ±5% tolerance, designed for through-hole axial applications. The component features flame retardant coating and safety-rated construction, making it suitable for industrial and safety-critical applications. The part is currently active in production with 1065 units in stock.

Substitute parts are identified when they maintain identical electrical specifications (resistance value, tolerance, power rating, temperature coefficient) and mechanical compatibility (package type, dimensions, termination count) while potentially offering different packaging formats or improved compliance certifications.

Substitute Part Grouping Explanation

Substitution eligibility for the Ohmite 90J180 is determined by strict equivalence across the following critical parameters:

• Resistance value: 180 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 11W (exact match required)
• Composition: Wirewound (exact match required)
• Package type: Axial (exact match required)
• Physical dimensions: 0.343" Dia x 1.811" L (exact match required)
• Temperature coefficient: ±30ppm/°C (exact match required)
• Termination count: 2 (exact match required)

The identified substitute part 90J180E meets all electrical and mechanical parameters. Differences are limited to packaging format (bulk versus box) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The 90J180E serves as a direct parametric equivalent to the 90J180. Both parts are manufactured by Ohmite and maintain identical electrical and mechanical specifications across all critical parameters.

The primary distinction between these parts is RoHS compliance status. The 90J180E achieves ROHS3 compliance, while the 90J180 is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the 90J180E is the appropriate selection. For applications without RoHS mandates, either part is electrically and mechanically interchangeable.

Both parts are active products with established inventory levels, ensuring supply continuity for production requirements.

Frequently Asked Questions (FAQ)

Q: Can the 90J180E replace the 90J180 in existing designs?

A: Yes. The 90J180E is electrically and mechanically identical to the 90J180. Both parts share the same resistance value (180 Ohms), tolerance (±5%), power rating (11W), temperature coefficient (±30ppm/°C), axial package configuration, and physical dimensions (0.343" Dia x 1.811" L). Direct substitution is valid from a component performance standpoint.

Q: What is the difference between these two parts?

A: The differences are limited to packaging format and compliance certification. The 90J180 is supplied in box packaging and is RoHS non-compliant. The 90J180E is supplied in bulk packaging and is ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Which part should I select for a new design?

A: Selection depends on regulatory requirements. If RoHS compliance is mandatory, specify the 90J180E. If RoHS compliance is not required, either part is acceptable. Consider packaging requirements: box packaging (90J180) or bulk packaging (90J180E).

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.343" diameter by 1.811" length (8.70mm x 46.00mm). They are mechanically interchangeable in PCB layouts and mechanical assemblies.

Q: Do these parts have the same temperature coefficient?

A: Yes. Both the 90J180 and 90J180E have a temperature coefficient of ±30ppm/°C, ensuring identical thermal performance across the operating temperature range.
