43F82RE Equivalent & Substitute Parts Reference

Part Overview

The 43F82RE is an 82 Ohm ±1% 3W axial wirewound resistor manufactured by Ohmite in the Ohmicone® 40 series. This through-hole component is actively produced and ROHS3 compliant. Equivalent and substitute parts are identified when component availability changes, supply chain constraints occur, or design flexibility permits mechanical or packaging variations while maintaining electrical performance within specified parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical parameters: resistance value (82 Ohms), tolerance (±1%), power rating (3W), composition (wirewound), package type (axial), and temperature coefficient (±20ppm/°C). All identified substitutes meet these core electrical specifications. Mechanical dimensions and packaging format (bulk vs. cut tape) may vary within acceptable tolerances for through-hole axial components. Compliance certifications (ROHS3, REACH, EAR99) are verified for each substitute to ensure regulatory compatibility.

Parameter Comparison

Engineering Selection Recommendations

RS02B82R00FE70 (Vishay Dale) and WW3FT82R0 (Stackpole Electronics Inc) are direct electrical and mechanical substitutes for 43F82RE. Both are ROHS3 compliant, actively produced, and available in higher inventory quantities. These parts are supplied in cut tape format rather than bulk packaging. 43F82R (Ohmite) is a parametric equivalent with identical electrical specifications and same-manufacturer sourcing; however, it is RoHS non-compliant and should be selected only when legacy design requirements or specific application constraints mandate this status. All three substitutes maintain the same axial package geometry, resistance value, tolerance, power rating, and temperature coefficient as the primary part.

Frequently Asked Questions (FAQ)

Q: Can RS02B82R00FE70 or WW3FT82R0 be used as direct replacements for 43F82RE in PCB assembly?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical resistance (82 Ω), tolerance (±1%), power rating (3W), composition (wirewound), package type (axial), and temperature coefficient (±20ppm/°C). Axial lead spacing and hole diameter compatibility are maintained across all three parts for through-hole mounting.

Q: What is the difference between bulk and cut tape packaging?

A: Bulk packaging supplies loose components; cut tape supplies components on adhesive tape in carrier strips. Both formats contain the same electrical component. Cut tape format (RS02B82R00FE70, WW3FT82R0) is suitable for automated assembly lines. Bulk format (43F82RE, 43F82R) is suitable for manual assembly or reel-fed processes.

Q: Why is 43F82R listed as RoHS non-compliant?

A: 43F82R does not meet ROHS3 compliance requirements. It is electrically identical to 43F82RE but manufactured to a different compliance standard. Selection of 43F82R should be limited to applications where RoHS non-compliance is explicitly permitted by design or regulatory requirements.

Q: Are there operating temperature differences between substitutes?

A: RS02B82R00FE70 operates from -65°C to 250°C. WW3FT82R0 operates from -55°C to 350°C. 43F82RE and 43F82R do not specify operating temperature ranges in provided data. For applications requiring extended temperature operation, WW3FT82R0 provides the widest operating range.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the design does not impose specific packaging format requirements. All substitutes meet the electrical specifications that determine circuit performance. Verify PCB footprint compatibility and assembly process requirements before implementation.
