Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RSMF3JB100K are identified based on the following critical parameters that determine functional equivalence:

• Resistance value: 100 kOhms
• Tolerance: ±5%
• Power rating: 3W
• Composition: Metal Oxide Film
• Package type: Axial
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 235°C
• Physical dimensions: 0.217" Dia x 0.591" L (5.50mm x 15.00mm)
• Compliance: ROHS3 Compliant

The RSMF3JT100K qualifies as a direct substitute because it maintains identical electrical and mechanical specifications. The only difference is packaging format (Cut Tape versus Bulk), which does not affect component performance or circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the RSMF3JB100K and RSMF3JT100K are Active status components manufactured by Stackpole Electronics Inc within the RSMF series. Both parts maintain identical electrical performance specifications and are ROHS3 compliant. Selection between these parts should be based on procurement and assembly requirements: the RSMF3JB100K is supplied in Bulk packaging, while the RSMF3JT100K is supplied in Cut Tape format. Circuit performance and reliability characteristics are equivalent across both packaging options.

Frequently Asked Questions (FAQ)

Q: Can RSMF3JT100K replace RSMF3JB100K in production assemblies?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. RSMF3JT100K (Cut Tape) is suitable for automated pick-and-place assembly, while RSMF3JB100K (Bulk) is suitable for manual assembly or bulk handling applications.

Q: Are there any performance differences between the substitute parts?

A: No. Both parts share identical resistance value (100 kOhms), tolerance (±5%), power rating (3W), temperature coefficient (±200ppm/°C), operating temperature range (-55°C to 235°C), and physical dimensions (0.217" Dia x 0.591" L).

Q: Do both parts meet the same compliance standards?

A: Yes. Both RSMF3JB100K and RSMF3JT100K are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements.

Q: What determines if a part can substitute for the RSMF3JB100K?

A: A substitute must match all critical parameters: 100 kOhms resistance, ±5% tolerance, 3W power rating, metal oxide film composition, axial package type, ±200ppm/°C temperature coefficient, -55°C to 235°C operating range, and 5.50mm x 15.00mm physical dimensions.

Q: Can parts from other manufacturers substitute for this Stackpole component?

A: Only if they meet all specified electrical and mechanical parameters. However, only the RSMF3JT100K from Stackpole Electronics Inc is listed as a qualified substitute based on the provided data.
