Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RSF2JB82K0 is determined by the following critical parameters:

• Resistance Value: Must be 82 kOhms
• Tolerance: Must be ±5%
• Composition: Must be Metal Oxide Film
• Package Type: Must be Axial
• Operating Temperature Range: Must support -55°C ~ 235°C
• Temperature Coefficient: Must be ±200ppm/°C
• Compliance: Must maintain ROHS3 compliance

The substitute part RSMF3JT82K0 meets all electrical and mechanical compatibility criteria. The primary difference is an increased power rating (3W versus 2W), which represents an upgrade capability rather than a limitation. Both parts share identical resistance, tolerance, composition, package configuration, and thermal characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the RSF2JB82K0 and RSMF3JT82K0 are Active products manufactured by Stackpole Electronics Inc and maintain full ROHS3 compliance. The RSMF3JT82K0 provides equivalent electrical performance with enhanced power dissipation capability. Selection between these parts depends on circuit power requirements and available board space. Both parts are suitable for applications within the specified operating temperature range of -55°C to 235°C.

Frequently Asked Questions (FAQ)

Q: Can RSMF3JT82K0 replace RSF2JB82K0 in existing designs?

A: Yes. Both parts share identical resistance (82 kOhms), tolerance (±5%), composition (Metal Oxide Film), axial package configuration, and thermal characteristics. The RSMF3JT82K0 provides 3W power rating compared to the 2W rating of RSF2JB82K0, making it suitable for applications requiring equal or lower power dissipation.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.217" diameter by 0.591" length (5.50mm x 15.00mm), ensuring mechanical compatibility in PCB layouts designed for either part.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RSF2JB82K0 and RSMF3JT82K0 are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements.

Q: What is the difference between Flame Retardant and Flame Proof coatings?

A: Both coatings provide safety features for metal oxide film resistors. The RSF2JB82K0 features Flame Retardant coating, while the RSMF3JT82K0 features Flame Proof coating. Both are acceptable for applications requiring safety-rated components.

Q: Are there packaging differences between these parts?

A: Yes. RSF2JB82K0 is supplied in Bulk packaging, while RSMF3JT82K0 is supplied in Cut Tape (CT) packaging. This affects order quantities and handling but does not impact electrical or mechanical compatibility.
