Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RSF2JA910R is determined by strict equivalence across the following critical parameters: resistance value (910 Ohms), tolerance (±5%), power rating (2W), composition (metal oxide film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 235°C), package configuration (axial), and termination count (2). All identified substitutes maintain these electrical and mechanical specifications. Packaging format (Cut Tape vs. Tape & Reel) and physical dimensions may vary within acceptable mechanical tolerances for through-hole mounting applications. Flame retardant and flame proof designations both satisfy safety requirements for this product category.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RSF2JA910R, RSF2JT910R, and RSMF2JT910R—are active production components from Stackpole Electronics Inc with full ROHS3 compliance and identical electrical specifications. Selection between these substitutes is determined by packaging and procurement requirements rather than electrical performance.

RSF2JA910R and RSF2JT910R are supplied in Cut Tape (CT) format, suitable for manual assembly and small-volume applications. RSMF2JT910R is supplied in Tape & Reel (TR) format, optimized for automated pick-and-place assembly and high-volume production environments. The RSMF2JT910R series features flame proof designation compared to the flame retardant coating of the RSF series; both designations satisfy safety requirements for this resistor category.

Physical dimensions differ slightly: RSF series measures 0.217" Dia x 0.591" L (5.50mm x 15.00mm), while RSMF series measures 0.177" Dia x 0.433" L (4.50mm x 11.00mm). These dimensional variations are within acceptable mechanical tolerances for standard through-hole PCB mounting.

Frequently Asked Questions (FAQ)

Q: Can RSF2JA910R be directly replaced with RSF2JT910R? A: Yes. Both parts share identical electrical specifications, resistance value, tolerance, power rating, temperature coefficient, and operating temperature range. The difference is packaging format (Cut Tape vs. Cut Tape with different tape specifications). Direct substitution is electrically and mechanically valid.

Q: What is the difference between RSF2JA910R and RSMF2JT910R? A: Electrical specifications are identical across resistance, tolerance, power rating, and temperature performance. Primary differences are: (1) packaging format—RSMF2JT910R uses Tape & Reel for automated assembly versus Cut Tape for manual assembly; (2) physical dimensions—RSMF series is slightly smaller; (3) safety designation—RSMF features flame proof versus RSF flame retardant coating. Both safety designations are compliant for this product category.

Q: Is RSMF2JT910R suitable for manual assembly applications? A: RSMF2JT910R is supplied in Tape & Reel format optimized for automated assembly. For manual assembly applications, RSF2JA910R or RSF2JT910R in Cut Tape format are more practical. However, RSMF2JT910R can be manually extracted from the reel if required by the application.

Q: Do all three parts have the same temperature performance? A: Yes. All three parts operate across -55°C to 235°C with identical temperature coefficient of ±200ppm/°C. Temperature performance is equivalent across all substitutes.

Q: Are there any compliance or certification differences? A: All three parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Compliance status is identical. The flame retardant and flame proof designations both satisfy safety requirements for metal oxide film resistors in this category.

Q: Which part should I select for high-volume production? A: RSMF2JT910R in Tape & Reel format is optimized for high-volume automated assembly. RSF2JA910R and RSF2JT910R in Cut Tape format are suitable for lower-volume or manual assembly scenarios.
