Parameter Comparison

Engineering Selection Recommendations

RSF2JT820R serves as a direct electrical equivalent to RSF2JB820R with identical specifications. Selection between these parts depends on procurement and assembly requirements. The Cut Tape packaging of RSF2JT820R accommodates automated pick-and-place assembly processes, while the Bulk packaging of RSF2JB820R suits manual assembly or kit-based applications.

RSMF3JT820R functions as an upgrade option when circuit design requires increased power dissipation. The 3W rating provides additional thermal margin compared to the 2W specification of the main part, while maintaining all other electrical and mechanical parameters. This part is suitable for applications where power dissipation calculations indicate thermal stress on the 2W component.

All three parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can RSF2JT820R replace RSF2JB820R in existing designs? A: Yes. RSF2JT820R is electrically and mechanically identical to RSF2JB820R. The only difference is packaging format (Cut Tape vs. Bulk). Direct substitution is valid for all circuit applications.

Q: When should RSMF3JT820R be used instead of RSF2JB820R? A: RSMF3JT820R should be selected when circuit analysis indicates power dissipation exceeding 2W at the 820 Ohm resistor location. The 3W rating provides additional thermal capacity while maintaining the same resistance, tolerance, and temperature characteristics.

Q: Are the physical dimensions identical across all three parts? A: Yes. All three parts share identical axial dimensions of 0.217" Dia x 0.591" L (5.50mm x 15.00mm), ensuring mechanical compatibility in PCB layouts and through-hole applications.

Q: Do packaging differences affect electrical performance? A: No. Packaging format (Bulk, Cut Tape, or Tape & Reel) does not affect electrical specifications. Selection is based on assembly process requirements and procurement logistics.

Q: Are all substitute parts compliant with current regulations? A: Yes. RSF2JT820R and RSMF3JT820R both maintain ROHS3 compliance and REACH unaffected status, matching the regulatory profile of RSF2JB820R.
