RSF3JB82K0 Equivalent & Substitute Parts

Part Overview

The RSF3JB82K0 is an 82 kOhms ±5% 3W through-hole axial resistor manufactured by Stackpole Electronics Inc. This metal oxide film resistor features flame retardant coating and safety design, suitable for applications requiring stable resistance values across a wide operating temperature range from -55°C to 235°C. The part is currently active in production with ROHS3 compliance and REACH unaffected status, making it suitable for modern electronic assemblies.

Equivalent parts are necessary when the primary manufacturer part becomes unavailable, when supply chain optimization is required, or when design flexibility allows for functionally compatible alternatives that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RSF3JB82K0 is determined by the following critical parameters:

• Resistance value: 82 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 3W (exact match required)
• Composition: Metal Oxide Film (exact match required)
• Package type: Axial (exact match required)
• Number of terminations: 2 (exact match required)
• Compliance: ROHS3 Compliant and REACH Unaffected status

The ROX3SJ82K from TE Connectivity Passive Product meets all critical substitution criteria. Both parts share identical electrical specifications (82 kOhms, ±5%, 3W) and mechanical configuration (axial package, 2 terminations). Both are ROHS3 compliant and REACH unaffected, ensuring regulatory compatibility in modern applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RSF3JB82K0 and ROX3SJ82K are active production parts with ROHS3 compliance and REACH unaffected status, confirming their suitability for current electronic assembly standards.

The RSF3JB82K0 operates across a wider temperature range (-55°C to 235°C) compared to the ROX3SJ82K (-55°C to 200°C). Applications requiring operation above 200°C must use the RSF3JB82K0. For applications within the -55°C to 200°C range, both parts are functionally equivalent.

The RSF3JB82K0 exhibits a lower temperature coefficient (±200ppm/°C) versus the ROX3SJ82K (±350ppm/°C), providing superior stability across temperature variations. Applications with stringent temperature stability requirements should prioritize the RSF3JB82K0.

Physical dimensions differ slightly between the two parts. The RSF3JB82K0 is larger (6.00mm diameter, 17.50mm length) than the ROX3SJ82K (5.50mm diameter, 16.00mm length). PCB layout constraints may influence part selection based on available space.

Frequently Asked Questions (FAQ)

Q: Can ROX3SJ82K replace RSF3JB82K0 in all applications?

A: ROX3SJ82K is functionally equivalent for applications operating within -55°C to 200°C. Applications requiring operation above 200°C must use RSF3JB82K0. Verify your circuit's maximum operating temperature before substitution.

Q: What are the key differences between these two parts?

A: The primary differences are operating temperature range (RSF3JB82K0 extends to 235°C versus ROX3SJ82K at 200°C), temperature coefficient stability (RSF3JB82K0 at ±200ppm/°C versus ROX3SJ82K at ±350ppm/°C), and physical dimensions (RSF3JB82K0 is slightly larger).

Q: Are both parts RoHS compliant?

A: Yes, both RSF3JB82K0 and ROX3SJ82K are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: Do the physical dimension differences affect PCB compatibility?

A: Both parts use axial packaging with 2 terminations and fit standard through-hole footprints. However, the RSF3JB82K0 is larger in diameter and length. Verify PCB layout clearances if space is constrained.

Q: Which part should I select for new designs?

A: Selection depends on application requirements. For maximum temperature range and stability, use RSF3JB82K0. For standard applications within -55°C to 200°C with adequate space, ROX3SJ82K offers equivalent performance with different availability and sourcing options.
