Substitute Part Grouping Explanation

Substitution eligibility for the RSMF12JB100R is determined by strict equivalence across the following critical parameters:

• Resistance value: 100 Ohms
• Tolerance: ±5%
• Power rating: 0.5W (1/2W)
• Composition: Metal Oxide Film
• Package configuration: Axial through-hole
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 200°C
• Physical dimensions: 0.091" Dia x 0.236" L (2.30mm x 6.00mm)
• Compliance certifications: ROHS3 Compliant, REACH Unaffected

The identified substitute part RSMF12JT100R matches all electrical and mechanical parameters. The only difference is the packaging format: the main part is supplied in Bulk packaging, while the substitute is supplied in Tape & Reel (TR) format. Both parts are from the same manufacturer series (RSMF) and maintain identical electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both RSMF12JB100R and RSMF12JT100R are active production parts from Stackpole Electronics Inc with identical electrical specifications and compliance certifications. Selection between these parts should be based on assembly process requirements and packaging logistics:

• RSMF12JB100R (Bulk packaging) is suitable for manual assembly, kit builds, or applications where individual component handling is standard practice.
• RSMF12JT100R (Tape & Reel packaging) is optimized for automated pick-and-place assembly systems and high-volume production environments.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across global markets. The identical physical dimensions, electrical characteristics, and thermal performance ensure direct functional interchangeability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can RSMF12JT100R be used as a direct replacement for RSMF12JB100R?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Bulk versus Tape & Reel). Direct substitution is valid for all circuit applications.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Bulk or Tape & Reel) does not affect the electrical characteristics, thermal performance, or reliability of the resistor. The component itself is identical.

Q: Are there any compliance differences between these parts?

A: No. Both parts carry identical RoHS3 compliance and REACH unaffected status. They meet the same regulatory requirements for global distribution.

Q: What is the primary reason to choose one part over the other?

A: Assembly process requirements determine the optimal choice. Tape & Reel packaging (RSMF12JT100R) integrates with automated assembly equipment, while Bulk packaging (RSMF12JB100R) supports manual or semi-automated processes.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical axial dimensions of 0.091" Dia x 0.236" L (2.30mm x 6.00mm), ensuring identical PCB footprint and mounting characteristics.

Q: Do these parts have the same temperature operating range?

A: Yes. Both parts operate across the identical temperature range of -55°C to 200°C with a temperature coefficient of ±200ppm/°C.
