RSF2JA82K0 Equivalent & Substitute Parts

Part Overview

The RSF2JA82K0 is a 2W metal oxide film axial resistor with 82 kOhms resistance and ±5% tolerance, manufactured by Stackpole Electronics Inc. This component is designed for through-hole applications requiring flame retardant coating and safety features. The part maintains Active product status with ROHS3 compliance and is suitable for applications across the -55°C to 235°C operating temperature range. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained while offering alternative packaging or enhanced performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RSF2JA82K0 are qualified based on the following criteria:

Electrical Parameters: Resistance value (82 kOhms), tolerance (±5%), and temperature coefficient (±200ppm/°C) must remain identical to ensure functional equivalence in circuit applications.

Mechanical Compatibility: Package type (Axial), physical dimensions (0.217" Dia x 0.591" L), and number of terminations (2) must match to ensure board-level compatibility and assembly feasibility.

Material Composition: Metal oxide film construction is maintained across all substitutes to preserve thermal and frequency response characteristics.

Compliance & Safety: All substitutes maintain ROHS3 compliance, REACH unaffected status, and equivalent safety certifications (flame retardant or flame proof coating).

Power Rating Variance: Substitutes may feature equal or higher power ratings (2W or greater) without affecting circuit performance, as higher ratings provide additional thermal margin.

Parameter Comparison

Engineering Selection Recommendations

The RSMF3JT82K0 qualifies as a direct substitute for the RSF2JA82K0 based on identical electrical parameters and mechanical compatibility. Both components maintain Active product status and full ROHS3 compliance. The primary distinction is the increased power rating (3W versus 2W) and packaging format (Cut Tape versus Tape & Box). The higher power rating of the substitute provides enhanced thermal performance without altering circuit behavior. Selection between these parts should be based on procurement requirements, packaging preferences, and inventory availability rather than electrical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can the RSMF3JT82K0 replace the RSF2JA82K0 in existing designs?

A: Yes. Both components share identical resistance (82 kOhms), tolerance (±5%), temperature coefficient (±200ppm/°C), and physical dimensions (0.217" Dia x 0.591" L). The substitute's higher power rating (3W) does not negatively impact circuit operation.

Q: What is the difference between the two parts?

A: The primary differences are power rating (2W versus 3W), packaging format (Tape & Box versus Cut Tape), and safety coating designation (Flame Retardant versus Flame Proof). Electrical and mechanical specifications are identical.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the RSF2JA82K0 and RSMF3JT82K0 maintain ROHS3 compliance and REACH unaffected status.

Q: Does the packaging format affect component performance?

A: No. Tape & Box and Cut Tape formats are packaging and delivery methods only. They do not affect electrical performance or board-level compatibility.

Q: Can I use the substitute in high-temperature applications?

A: Yes. Both components operate across the -55°C to 235°C temperature range with identical temperature coefficients (±200ppm/°C).
