Substitute Part Grouping Explanation

The RSMF3JB5R10 has one identified substitute part: RSMF3JT5R10. 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 key parameters:

• Resistance value: 5.1 Ohms
• Tolerance: ±5%
• Power rating: 3W
• Composition: Metal Oxide Film
• Package case: Axial
• Physical dimensions: 0.217" Dia x 0.591" L (5.50mm x 15.00mm)
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 235°C
• Features: Flame Proof, Safety
• Compliance: ROHS3 Compliant

The primary difference between these parts is packaging format: RSMF3JB5R10 is supplied in bulk packaging, while RSMF3JT5R10 is supplied in tape and reel (TR) format.

Parameter Comparison

Engineering Selection Recommendations

Both RSMF3JB5R10 and RSMF3JT5R10 are active production parts from Stackpole Electronics Inc with identical electrical performance and mechanical compatibility. Selection between these parts should be based on packaging requirements and assembly process specifications. The bulk packaging format (RSMF3JB5R10) is suitable for manual assembly or small-volume applications, while the tape and reel format (RSMF3JT5R10) is optimized for automated pick-and-place assembly processes. Both parts maintain ROHS3 compliance and are suitable for applications requiring flame-proof and safety-rated resistors across the -55°C to 235°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can RSMF3JT5R10 be used as a direct replacement for RSMF3JB5R10?

A: Yes. Both parts have identical electrical specifications (5.1 Ohms ±5%, 3W), mechanical dimensions (0.217" Dia x 0.591" L), composition (metal oxide film), and operating characteristics. The only difference is packaging format.

Q: What is the difference between bulk and tape & reel packaging?

A: Bulk packaging (RSMF3JB5R10) supplies components loose in a container, suitable for manual handling and small-volume assembly. Tape and reel packaging (RSMF3JT5R10) supplies components on continuous tape wound on a reel, optimized for automated assembly equipment.

Q: Are both parts RoHS compliant?

A: Yes. Both RSMF3JB5R10 and RSMF3JT5R10 are ROHS3 compliant.

Q: What is the operating temperature range for these resistors?

A: Both parts operate across -55°C to 235°C with a temperature coefficient of ±200ppm/°C.

Q: Can these parts be used in applications requiring flame-proof components?

A: Yes. Both RSMF3JB5R10 and RSMF3JT5R10 feature flame-proof and safety ratings suitable for such applications.
