Key Parameters

Substitute Part Grouping Explanation

Substitution between RSF2JB24K0 and RSMF2JT24K0 is valid based on the following criteria:

Both parts maintain identical electrical specifications: 24 kOhms resistance, ±5% tolerance, 2W power rating, metal oxide film composition, ±200ppm/°C temperature coefficient, and -55°C to 235°C operating temperature range. Both are manufactured by Stackpole Electronics Inc and comply with ROHS3 and REACH requirements.

The primary difference is packaging format: RSF2JB24K0 is supplied in Bulk packaging, while RSMF2JT24K0 is supplied in Tape & Reel (TR) format. Additionally, the RSMF series features flame proof design compared to the flame retardant coating of the RSF series. Physical dimensions differ slightly due to series design variations, with RSMF2JT24K0 measuring 0.177" Dia x 0.433" L versus RSF2JB24K0 at 0.217" Dia x 0.591" L.

Parameter Comparison

Engineering Selection Recommendations

Selection between RSF2JB24K0 and RSMF2JT24K0 depends on supply chain and assembly requirements rather than electrical performance. Both parts are active products with identical electrical characteristics and regulatory compliance.

RSF2JB24K0 in bulk packaging is suitable for applications requiring manual component selection or small-volume assembly operations. RSMF2JT24K0 in tape and reel format is appropriate for automated pick-and-place assembly processes and high-volume production environments.

The dimensional difference between the two parts must be considered for PCB layout and mechanical clearance. RSMF2JT24K0 occupies less board space due to its smaller diameter and length. Both parts maintain equivalent thermal and electrical performance across the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can RSMF2JT24K0 replace RSF2JB24K0 in existing designs?

A: Yes, from an electrical standpoint. Both parts have identical resistance, tolerance, power rating, and operating temperature specifications. However, the physical dimensions differ, so PCB layout and mechanical clearance must be verified. RSMF2JT24K0 is smaller, which may require layout adjustments.

Q: What is the difference between flame retardant and flame proof coatings?

A: Both RSF and RSMF series provide safety features. RSF2JB24K0 features flame retardant coating, while RSMF2JT24K0 features flame proof design. Both meet safety standards for their respective applications.

Q: Which packaging format should I choose for production?

A: Bulk packaging (RSF2JB24K0) is suitable for manual assembly and low-volume applications. Tape & Reel format (RSMF2JT24K0) is designed for automated assembly lines and high-volume manufacturing.

Q: Are both parts RoHS and REACH compliant?

A: Yes, both RSF2JB24K0 and RSMF2JT24K0 are ROHS3 compliant and REACH unaffected.

Q: What is the temperature coefficient specification?

A: Both parts have a temperature coefficient of ±200ppm/°C, ensuring stable resistance performance across the -55°C to 235°C operating range.
