Parameter Comparison

Engineering Selection Recommendations

RNF18FTD80K6 (Direct Substitute): This part is electrically and mechanically identical to the RNF18FAD80K6, with the only difference being the packaging format (Tape & Reel instead of Tape & Box). Selection of this part is appropriate when Tape & Reel packaging is acceptable for assembly processes. Both parts maintain ROHS3 compliance and active product status.

RNMF14FTD80K6 (Upgraded Substitute): This part provides the same resistance and tolerance specifications but with doubled power rating (0.25W vs. 0.125W). The RNMF14FTD80K6 is suitable for applications requiring higher power dissipation capability while maintaining identical electrical performance. Physical dimensions are marginally different (0.070" vs. 0.071" diameter), which may require verification for space-constrained PCB layouts. This part maintains ROHS3 compliance and active product status.

Frequently Asked Questions (FAQ)

Q: Can RNF18FTD80K6 be used as a direct replacement for RNF18FAD80K6? A: Yes. Both parts have identical electrical specifications (80.6 kOhms ±1%, 0.125W, ±100ppm/°C) and mechanical dimensions (0.071" Dia x 0.130" L). The difference is packaging format: Tape & Reel versus Tape & Box. Compatibility depends on assembly equipment capability to handle the respective packaging format.

Q: When should RNMF14FTD80K6 be selected over RNF18FAD80K6? A: The RNMF14FTD80K6 should be selected when the application requires higher power dissipation (0.25W vs. 0.125W). Electrical performance remains identical. Physical dimensions differ slightly (0.070" vs. 0.071" diameter), requiring PCB layout verification for space-critical designs.

Q: Are all three parts RoHS compliant? A: Yes. RNF18FAD80K6, RNF18FTD80K6, and RNMF14FTD80K6 are all ROHS3 compliant.

Q: What is the difference between RNF and RNMF series designations? A: The RNF series represents standard metal film resistors at 0.125W rating. The RNMF series represents mini metal film resistors at 0.25W rating. Both series share identical electrical characteristics for the 80.6 kOhms ±1% value, with the RNMF offering higher power capability in a slightly more compact diameter.

Q: Can these parts be used interchangeably in all applications? A: RNF18FAD80K6 and RNF18FTD80K6 are fully interchangeable electrically and mechanically. RNMF14FTD80K6 is electrically compatible but has a slightly different diameter and higher power rating. Verify PCB layout clearances and confirm that the higher power rating does not introduce thermal management changes to the circuit design.
