Substitute Part Grouping Explanation

The RSMF3JB24R0 has one identified substitute: RSMF3JT24R0. 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: 24 Ohms
• Tolerance: ±5%
• Power rating: 3W
• Composition: Metal Oxide Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 235°C
• Physical dimensions: 0.217" Dia x 0.591" L (5.50mm x 15.00mm)
• Features: Flame Proof, Safety
• Compliance: ROHS3 Compliant, REACH Unaffected

The only difference between these parts is the packaging format: RSMF3JB24R0 is supplied in Bulk packaging, while RSMF3JT24R0 is supplied in Cut Tape (CT) packaging. This distinction affects procurement and assembly processes but does not alter component performance or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both RSMF3JB24R0 and RSMF3JT24R0 are active production parts with identical electrical performance and compliance certifications. Selection between these parts should be based on procurement and assembly requirements:

RSMF3JB24R0 in Bulk packaging is suitable for high-volume applications where components are manually sorted or processed through custom assembly workflows.

RSMF3JT24R0 in Cut Tape (CT) packaging is suitable for automated pick-and-place assembly processes and tape-fed component handling systems.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across global markets.

Frequently Asked Questions (FAQ)

Q: Can RSMF3JT24R0 replace RSMF3JB24R0 in circuit design?

A: Yes. Both parts have identical electrical specifications, resistance value, tolerance, power rating, temperature coefficient, and operating temperature range. Substitution is electrically valid.

Q: What is the difference between Bulk and Cut Tape (CT) packaging?

A: Bulk packaging supplies loose components suitable for manual handling and custom assembly processes. Cut Tape (CT) packaging supplies components on continuous tape suitable for automated pick-and-place equipment. The components themselves are identical.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both RSMF3JB24R0 and RSMF3JT24R0 are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance restrictions.

Q: Can these resistors operate at the full temperature range specified?

A: Yes. Both parts are rated for continuous operation from -55°C to 235°C with a temperature coefficient of ±200ppm/°C, maintaining specified tolerance across this range.

Q: Are the physical dimensions identical between substitute parts?

A: Yes. Both parts have identical axial package dimensions of 0.217" diameter by 0.591" length (5.50mm x 15.00mm), ensuring mechanical compatibility in PCB layouts and through-hole applications.
