Key Parameters

Substitute Part Grouping Explanation

The RSMF2JT910R qualifies as a substitute for the RSF1JB910R based on the following critical parameters:

• Identical resistance value: 910 Ohms
• Identical tolerance: ±5%
• Identical composition: Metal Oxide Film
• Identical package type: Axial
• Identical temperature coefficient: ±200ppm/°C
• Identical operating temperature range: -55°C ~ 235°C
• Identical termination count: 2
• Identical RoHS and REACH compliance status

The primary difference is the power rating upgrade from 1W to 2W and packaging format change from bulk to tape & reel. The RSMF2JT910R maintains all electrical and mechanical compatibility while providing increased power dissipation capability.

Parameter Comparison

Engineering Selection Recommendations

Both the RSF1JB910R and RSMF2JT910R are active production parts manufactured by Stackpole Electronics Inc with full ROHS3 compliance and REACH unaffected status. The RSMF2JT910R provides a direct electrical substitute with identical resistance, tolerance, temperature coefficient, and operating range specifications. The 2W power rating of the RSMF2JT910R accommodates applications requiring higher power dissipation than the 1W RSF1JB910R. Selection between these parts depends on circuit power requirements and packaging format compatibility. The tape & reel packaging of the RSMF2JT910R is suitable for automated assembly processes, while the bulk packaging of the RSF1JB910R supports manual assembly workflows.

Frequently Asked Questions (FAQ)

Q: Can the RSMF2JT910R directly replace the RSF1JB910R in existing designs?

A: Yes. The RSMF2JT910R maintains identical electrical specifications including resistance value, tolerance, temperature coefficient, and operating temperature range. The axial package type and physical dimensions are compatible. The higher power rating (2W vs 1W) provides additional thermal margin without affecting circuit performance.

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

A: Both coatings provide safety features for metal oxide film resistors. Flame retardant coating (RSF1JB910R) resists flame propagation, while flame proof coating (RSMF2JT910R) provides enhanced flame resistance. Both meet safety standards for through-hole resistor applications.

Q: Does packaging format affect electrical performance?

A: No. Bulk and tape & reel packaging formats do not affect electrical performance. The difference is in handling and assembly methodology. Tape & reel packaging is optimized for automated pick-and-place assembly, while bulk packaging is suitable for manual assembly or lower-volume applications.

Q: Are there any compliance differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across applications.

Q: When should I select the 2W RSMF2JT910R over the 1W RSF1JB910R?

A: Select the RSMF2JT910R when circuit analysis indicates power dissipation approaching or exceeding 1W, or when design margins require additional thermal headroom. The 2W rating provides operational safety for higher-power applications while maintaining all other electrical characteristics.
