RSF2JB100R Equivalent & Substitute Parts

Part Overview

The RSF2JB100R is a 100 Ohms ±5% 2W through-hole resistor manufactured by Stackpole Electronics Inc. This metal oxide film resistor features flame retardant coating and safety design, operating across a temperature range of -55°C to 235°C. The part is currently active in production with ROHS3 compliance and REACH unaffected status. Substitute parts are identified when packaging formats or specific product series variants are required while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RSF2JB100R is determined by the following critical parameters: resistance value (100 Ohms), tolerance (±5%), power rating (2W), composition (metal oxide film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C to 235°C), and axial package configuration. Substitute parts must match all electrical specifications and maintain axial through-hole termination. Packaging format variations (bulk versus cut tape) and minor dimensional differences within the axial envelope are permitted substitution variables. Series designation changes (RSF to RSMF) are acceptable when all electrical and thermal parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RSF2JB100R, RSF2JT100R, and RSMF2JT100R—are active production components from Stackpole Electronics Inc with identical electrical performance and full regulatory compliance. Selection between these parts is determined by packaging and dimensional requirements rather than electrical characteristics.

RSF2JB100R in bulk packaging is suitable for high-volume manufacturing environments with integrated component handling systems. RSF2JT100R in cut tape format provides the same electrical specifications with standard tape-and-reel packaging for automated assembly lines. RSMF2JT100R represents a compact variant within the same series family, offering reduced physical dimensions (4.50mm x 11.00mm versus 5.50mm x 15.00mm) while maintaining all electrical parameters, making it applicable where space constraints exist on printed circuit boards.

All parts maintain ROHS3 compliance and REACH unaffected status, confirming suitability for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can RSF2JT100R replace RSF2JB100R in production? A: Yes. Both parts are electrically identical 100 Ohm ±5% 2W metal oxide film resistors. The difference is packaging format: RSF2JB100R is supplied in bulk, while RSF2JT100R is supplied in cut tape. Selection depends on assembly process requirements.

Q: What is the primary difference between RSF2JT100R and RSMF2JT100R? A: Both are cut tape packaged and electrically equivalent. RSMF2JT100R has reduced physical dimensions (4.50mm x 11.00mm) compared to RSF2JT100R (5.50mm x 15.00mm). Choose RSMF2JT100R when board space is limited.

Q: Are all three parts suitable for the same circuit applications? A: Yes, provided the physical dimensions of the selected part fit the PCB layout. All three deliver identical electrical performance: 100 Ohms ±5% at 2W with ±200ppm/°C temperature coefficient across -55°C to 235°C.

Q: Do packaging format changes affect electrical performance? A: No. Bulk and cut tape packaging formats do not alter resistance, tolerance, power rating, or thermal characteristics. Packaging selection is based on manufacturing process compatibility.

Q: Which part should be selected for space-constrained designs? A: RSMF2JT100R offers the smallest footprint at 4.50mm x 11.00mm while maintaining full electrical specifications.
