Parameter Comparison

Engineering Selection Recommendations

RSMF3JT30K0 (Upgrade Option): This substitute provides increased power dissipation at 3W while maintaining all electrical specifications of the RSF2JB30K0. The upgrade is suitable for applications requiring enhanced thermal margin. Both parts are ROHS3 compliant and REACH unaffected. The Tape & Reel packaging format supports automated assembly processes. Physical dimensions remain compatible with axial package specifications.

RSMF2JT30K0 (Manufacturer Recommended): This substitute matches the 2W power rating of the RSF2JB30K0 while offering Tape & Reel packaging for high-volume production environments. All electrical parameters remain identical. The part is ROHS3 compliant and REACH unaffected. Stackpole Electronics Inc designates this as the manufacturer-recommended equivalent, with significantly higher inventory availability (16041 units in stock).

Both substitutes maintain compliance certifications (ROHS3, REACH unaffected, ECCN EAR99, HTSUS 8533.21.0090) and are classified as active products.

Frequently Asked Questions (FAQ)

Q: Can RSMF3JT30K0 be used as a direct replacement for RSF2JB30K0? A: Yes. The RSMF3JT30K0 maintains identical resistance (30 kOhms), tolerance (±5%), composition (metal oxide film), and operating temperature range (-55°C ~ 235°C). The increased 3W power rating provides additional thermal capability. The primary difference is packaging format (Tape & Reel vs. Bulk) and physical dimensions within the axial package specification.

Q: What is the difference between RSMF2JT30K0 and RSF2JB30K0? A: Both parts share identical electrical specifications: 30 kOhms ±5% at 2W with metal oxide film composition. The RSMF2JT30K0 differs in packaging format (Tape & Reel vs. Bulk) and physical dimensions (4.50mm x 11.00mm vs. 5.50mm x 15.00mm). The RSMF2JT30K0 features flame proof coating compared to flame retardant on the RSF2JB30K0.

Q: Are there any compatibility concerns when substituting these parts? A: All three parts are axial through-hole resistors with identical electrical parameters and two terminations. Compatibility depends on PCB layout and mechanical clearance. The RSMF2JT30K0 has smaller physical dimensions (4.50mm x 11.00mm) compared to RSF2JB30K0 (5.50mm x 15.00mm), which may affect board layout. The RSMF3JT30K0 maintains the same dimensions as RSF2JB30K0.

Q: Which substitute should be selected for high-volume production? A: The RSMF2JT30K0 is the manufacturer-recommended option with Tape & Reel packaging and the highest inventory availability (16041 units). This format is optimized for automated assembly processes and high-volume manufacturing environments.

Q: Do all substitutes meet the same regulatory requirements? A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8533.21.0090. Compliance certifications are identical across all options.
