Substitute Part Grouping Explanation

The RSMF5JB100R has one identified substitute: RSMF5JT100R. Both parts are manufactured by Stackpole Electronics Inc within the RSMF series and share identical electrical and mechanical specifications. The substitution is valid based on the following matching parameters:

• Resistance value: 100 Ohms
• Tolerance: ±5%
• Power rating: 5W
• Composition: Metal Oxide Film
• Package case: Axial
• Physical dimensions: 0.236" Dia x 0.689" L (6.00mm x 17.50mm)
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 235°C
• Features: Flame Proof, Safety
• RoHS compliance: ROHS3 Compliant

The only difference between these parts is the packaging format: RSMF5JB100R is supplied in Bulk packaging, while RSMF5JT100R is supplied in Tape & Reel (TR) format.

Parameter Comparison

Engineering Selection Recommendations

Both RSMF5JB100R and RSMF5JT100R are active production parts with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on packaging requirements and supply chain considerations. The RSMF5JB100R in Bulk packaging is suitable for manual assembly or small-batch applications. The RSMF5JT100R in Tape & Reel format is optimized for automated assembly processes and high-volume production environments. Both parts maintain identical electrical performance and thermal characteristics across the specified operating temperature range of -55°C to 235°C.

Frequently Asked Questions (FAQ)

Q: Can RSMF5JT100R be used as a direct replacement for RSMF5JB100R?

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

Q: What is the difference between Bulk and Tape & Reel packaging?

A: Bulk packaging supplies loose components suitable for manual handling and small-quantity applications. Tape & Reel packaging supplies components on continuous tape for automated pick-and-place assembly equipment. The components themselves are identical.

Q: Are there any thermal or performance differences between these substitutes?

A: No. Both parts share identical temperature coefficients (±200ppm/°C), operating temperature ranges (-55°C ~ 235°C), and power ratings (5W). Performance is equivalent across all specified electrical parameters.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RSMF5JB100R and RSMF5JT100R are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: Which part should be selected for automated assembly?

A: RSMF5JT100R in Tape & Reel format is designed for automated assembly processes. RSMF5JB100R in Bulk format is suitable for manual assembly or applications where automated handling is not required.
