Key Parameters

Substitute Part Grouping Explanation

The RSMF2JB24K0 and RSMF2JT24K0 are functionally equivalent resistors within the Stackpole RSMF series. Both parts share identical electrical specifications: 24 kOhms resistance, ±5% tolerance, 2W power rating, metal oxide film composition, and identical physical dimensions. The substitution is valid based on matching the following critical parameters:

• Resistance value and tolerance
• Power dissipation capability
• Thermal characteristics (temperature coefficient and operating range)
• Physical form factor and dimensions
• Material composition and construction method

The primary distinction between these parts is packaging format: RSMF2JB24K0 is supplied in bulk packaging, while RSMF2JT24K0 is supplied in tape and reel format. This difference does not affect electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both RSMF2JB24K0 and RSMF2JT24K0 are active production parts from Stackpole Electronics Inc with identical electrical and mechanical specifications. Selection between these parts should be based on procurement and assembly requirements:

RSMF2JB24K0 (bulk packaging) is suitable for manual assembly, prototype builds, or applications where component handling flexibility is prioritized.

RSMF2JT24K0 (tape and reel packaging) is suitable for automated assembly processes, high-volume production runs, and applications requiring component feeding through pick-and-place equipment.

Both parts maintain ROHS3 compliance and are suitable for applications operating across the -55°C to 235°C temperature range. The identical physical dimensions ensure direct mechanical compatibility in circuit board layouts.

Frequently Asked Questions (FAQ)

Q: Can RSMF2JT24K0 replace RSMF2JB24K0 in my circuit design?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format. RSMF2JT24K0 can be used in any application where RSMF2JB24K0 is specified, provided your assembly process can accommodate tape and reel packaging.

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

A: Bulk packaging supplies loose components suitable for manual handling and small-quantity assembly. Tape and reel packaging supplies components on continuous carrier tape wound on reels, designed for automated pick-and-place assembly equipment.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts measure 0.177" diameter by 0.433" length (4.50mm x 11.00mm). They are mechanically interchangeable on circuit boards.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RSMF2JB24K0 and RSMF2JT24K0 are ROHS3 compliant and REACH unaffected.

Q: Which part should I select for high-volume production?

A: RSMF2JT24K0 in tape and reel format is optimized for high-volume automated assembly processes.

Q: Which part should I select for prototype or low-volume builds?

A: RSMF2JB24K0 in bulk packaging is suitable for prototype development and low-volume manual assembly.
