Ohmite 41F82RE Equivalent & Substitute Parts

Part Overview

The Ohmite 41F82RE is a 1W, 82 Ohms ±1% through-hole resistor with axial wirewound construction, part of the Ohmicone® 40 series. This component is designed for applications requiring precision resistive elements with stable performance across extended temperature ranges. The part is currently active in production with 863 units in stock. Substitute parts are identified when packaging, inventory availability, or compliance requirements necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 41F82RE is determined by strict equivalence across the following critical parameters:

• Resistance value: 82 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Composition: Wirewound
• Package configuration: Axial
• Temperature coefficient: ±20ppm/°C
• Physical dimensions: 0.126" Dia × 0.437" L (3.20mm × 11.10mm)
• Termination count: 2

The identified substitute, Ohmite 41F82R, matches all electrical and mechanical parameters. Differences exist only in packaging format (bulk versus box) and regulatory compliance status, which do not affect functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 41F82RE and 41F82R are active production components from Ohmite with identical electrical performance and mechanical form factor. Selection between these parts should be based on the following criteria:

The 41F82RE is the preferred choice for applications subject to RoHS compliance requirements or where regulatory documentation mandates lead-free construction. This part carries RoHS Compliant certification and is packaged in box format.

The 41F82R is functionally equivalent but carries RoHS Non-Compliant status and is supplied in bulk packaging. This part is suitable for applications where RoHS compliance is not a requirement and bulk packaging is acceptable for manufacturing workflows.

Both parts share identical resistance value, tolerance, power rating, temperature coefficient, and physical dimensions, ensuring direct functional interchangeability in circuit design without performance degradation.

Frequently Asked Questions (FAQ)

Q: Can the 41F82R be used as a direct replacement for the 41F82RE in all applications?

A: The 41F82R is electrically and mechanically identical to the 41F82RE. Direct substitution is possible in applications where RoHS compliance is not mandated. If your application or supply chain requires RoHS Compliant components, the 41F82RE must be used.

Q: What is the difference between box and bulk packaging?

A: Box packaging (41F82RE) typically includes individual component packaging suitable for controlled inventory and traceability. Bulk packaging (41F82R) supplies components in larger quantities without individual wrapping, reducing per-unit cost but requiring different handling and inventory management procedures.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the 41F82RE and 41F82R measure 0.126" diameter by 0.437" length (3.20mm × 11.10mm). They are mechanically interchangeable on PCBs and in through-hole applications.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical characteristics. Both parts deliver identical resistance value, tolerance, temperature coefficient, and power handling capability.

Q: Which part should I specify for new designs?

A: Specify the 41F82RE for designs requiring RoHS Compliant documentation and certification. This ensures compliance with current environmental regulations and supply chain requirements. The 41F82R may be used only when RoHS compliance is explicitly not required by your application or regulatory framework.
