RSMF2JB100K Equivalent & Substitute Parts

Part Overview

The RSMF2JB100K is a 100 kOhms ±5% 2W through-hole resistor in axial configuration, manufactured by Stackpole Electronics Inc. This metal oxide film resistor features flame-proof construction with safety certification and is designed for applications requiring reliable performance across industrial temperature ranges. The part is currently active in production with ROHS3 compliance and REACH unaffected status. Substitute parts are identified to address packaging availability, inventory levels, and equivalent electrical performance across the RSMF and RSF series.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RSMF2JB100K is determined by the following critical parameters: resistance value (100 kOhms), tolerance (±5%), power rating (2W), composition (metal oxide film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 235°C), axial package configuration, and compliance certifications (ROHS3, REACH unaffected).

The RSMF2JT100K qualifies as a direct substitute, maintaining identical electrical specifications and physical package dimensions while differing only in packaging format (cut tape versus bulk). Both parts belong to the RSMF series and share identical flame-proof safety features.

The RSF2JT100K qualifies as a manufacturer-recommended substitute within the RSF series. While maintaining all critical electrical parameters, this part features a larger physical dimension (0.217" Dia x 0.591" L versus 0.177" Dia x 0.433" L) and employs flame retardant coating rather than flame-proof construction. These dimensional and construction differences require verification of mechanical fit and thermal performance in the target application.

Parameter Comparison

Engineering Selection Recommendations

The RSMF2JT100K is the preferred direct substitute for the RSMF2JB100K. Both parts maintain identical electrical specifications, temperature performance, and physical dimensions. The substitution addresses packaging format differences (cut tape availability versus bulk packaging) without introducing any electrical or mechanical compatibility concerns. Both parts carry active product status with full ROHS3 compliance and REACH unaffected certification.

The RSF2JT100K is available as a manufacturer-recommended alternative within the RSF series. This part maintains all critical electrical parameters and compliance certifications. However, the increased physical dimensions (0.217" Dia x 0.591" L) and construction method change (flame retardant coating versus flame-proof) require confirmation of mechanical fit within the target assembly and validation of thermal performance characteristics specific to the application environment.

Frequently Asked Questions (FAQ)

Q: Can RSMF2JT100K replace RSMF2JB100K in all applications? A: Yes. The RSMF2JT100K provides identical electrical performance and physical dimensions. The only difference is packaging format (cut tape versus bulk). No design or assembly modifications are required.

Q: What are the key differences between RSMF2JT100K and RSF2JT100K? A: Both parts share identical electrical specifications (100 kOhms, ±5%, 2W, ±200ppm/°C, -55°C ~ 235°C). The RSF2JT100K has larger physical dimensions (0.217" Dia x 0.591" L versus 0.177" Dia x 0.433" L) and uses flame retardant coating instead of flame-proof construction. Mechanical fit and thermal requirements must be verified before substitution.

Q: Are all three parts ROHS3 compliant? A: Yes. RSMF2JB100K, RSMF2JT100K, and RSF2JT100K are all ROHS3 compliant and REACH unaffected.

Q: What packaging formats are available? A: RSMF2JB100K is supplied in bulk packaging. RSMF2JT100K and RSF2JT100K are supplied in cut tape (CT) format.

Q: Does the temperature coefficient differ between substitute parts? A: No. All three parts maintain ±200ppm/°C temperature coefficient and operate across the -55°C ~ 235°C range.

Q: Can RSF2JT100K be used in space-constrained applications? A: The RSF2JT100K has larger dimensions than the RSMF series. Applications with strict space requirements must confirm mechanical fit before substitution.
