Substitute Part Grouping Explanation
Substitution eligibility is determined by matching the following critical parameters:
- Resistance Value: 62 kOhms (exact match required)
- Tolerance: ±5% (exact match required)
- Power Rating: 2W (exact match required)
- Composition: Metal Oxide Film (exact match required)
- Package Type: Axial (exact match required)
- Termination Count: 2 (exact match required)
- Compliance: ROHS3 Compliant (required for equivalent substitution)
The substitute part RSF200JB-73-62K meets all critical electrical and mechanical parameters. Physical dimensions vary between the main part and substitute, with the substitute featuring a larger diameter (0.197" vs 0.157") and length (0.610" vs 0.472"). Both parts operate within overlapping temperature ranges suitable for industrial applications.

Engineering Selection Recommendations
Both the MOS2CT52R623J and RSF200JB-73-62K are Active status products with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on the following criteria:
MOS2CT52R623J (KOA Speer) is selected when:
- Compact form factor is required (smaller diameter and length)
- Space-constrained PCB layouts necessitate minimal component footprint
- Flame retardant coating specification is explicitly required
RSF200JB-73-62K (YAGEO) is selected when:
- Extended operating temperature capability to 235°C is required
- Larger physical dimensions are acceptable within the application
- Flame proof construction meets application safety requirements
- Higher inventory availability is advantageous
Both parts satisfy identical electrical specifications (62 kOhms, ±5%, 2W) and are suitable for direct substitution in circuits where the physical dimension differences do not create layout conflicts.
Frequently Asked Questions (FAQ)
Q: Can RSF200JB-73-62K replace MOS2CT52R623J in all applications?
A: RSF200JB-73-62K is electrically equivalent and meets all compliance requirements. Physical dimensions differ; verify PCB layout accommodates the larger form factor (0.197" diameter × 0.610" length versus 0.157" diameter × 0.472" length).
Q: What is the primary difference between these two resistors?
A: The primary differences are physical dimensions and maximum operating temperature. RSF200JB-73-62K operates to 235°C versus 200°C for MOS2CT52R623J. Both deliver identical electrical performance at 62 kOhms ±5% 2W.
Q: Are both parts ROHS3 compliant?
A: Yes. Both MOS2CT52R623J and RSF200JB-73-62K are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
Q: Does packaging format affect substitution eligibility?
A: Both parts use axial through-hole packaging. The main part is supplied in Cut Tape format while the substitute is supplied in Bulk format. This does not affect electrical or mechanical compatibility; it affects only procurement and handling logistics.
Q: What is the temperature coefficient difference?
A: MOS2CT52R623J specifies ±300ppm/°C temperature coefficient. RSF200JB-73-62K does not provide temperature coefficient data in the available specifications. Both operate within their specified temperature ranges with metal oxide film composition.
Q: Can these parts be used interchangeably on existing PCBs?
A: Electrical interchangeability is confirmed. Physical interchangeability requires verification that PCB layout and component spacing accommodate the larger dimensions of RSF200JB-73-62K (0.197" diameter × 0.610" length).
