Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MOS2CT52R910J is determined by the following critical parameters:

• Resistance value: 91 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 2W (exact match required)
• Composition: Metal Oxide Film (exact match required)
• Package configuration: Axial through-hole (exact match required)
• Operating temperature range: Minimum -55°C to maximum ≥200°C
• RoHS compliance: ROHS3 Compliant (minimum requirement)

The RSF200JB-73-91R from YAGEO meets all substitution criteria. Both parts share identical electrical specifications and axial package configuration. The YAGEO substitute provides an extended operating temperature range (-55°C ~ 235°C) and flame proof characteristics, offering equivalent or superior performance for the specified application.

Parameter Comparison

Engineering Selection Recommendations

Both the MOS2CT52R910J and RSF200JB-73-91R are active production parts with ROHS3 compliance and unlimited moisture sensitivity ratings. Selection between these parts should be based on:

• Availability and lead time requirements
• Physical dimensions and PCB layout constraints (MOS2CT52R910J: 4.00mm Dia x 12.00mm L; RSF200JB-73-91R: 5.00mm Dia x 15.50mm L)
• Packaging format preference (MOS2CT52R910J supplied in Tape & Reel; RSF200JB-73-91R supplied in Bulk)
• Extended temperature performance needs (RSF200JB-73-91R rated to 235°C versus 200°C for MOS2CT52R910J)

Frequently Asked Questions (FAQ)

Q: Can RSF200JB-73-91R be used as a direct replacement for MOS2CT52R910J?
