Parameter Comparison

Engineering Selection Recommendations

RNF12FTD1K00 (Stackpole Electronics Inc): Direct substitute from the same manufacturer and series. Identical electrical and mechanical specifications. Differs only in packaging format (Cut Tape vs. Tape & Box). Maintains all compliance certifications. Suitable for direct replacement in production environments where packaging format change is acceptable.

CMF551K0000FKEA (Vishay Dale): Cross-manufacturer substitute with equivalent electrical performance. Meets all core electrical parameters and compliance requirements. Operating temperature range extends to 175°C, providing enhanced thermal capability. Includes moisture resistance feature in addition to flame retardant coating. Physical dimensions are smaller (0.090" Dia x 0.240" L vs. 0.108" Dia x 0.344" L). Suitable for applications requiring extended temperature performance or moisture-resistant construction.

Frequently Asked Questions (FAQ)

Q: Can RNF12FTD1K00 be used as a direct replacement for RNF12FAD1K00?

A: Yes. Both parts are from Stackpole Electronics Inc RNF series with identical electrical specifications (1 kOhms ±1%, 0.5W, ±100ppm/°C), mechanical configuration (axial through-hole), and compliance status (ROHS3, REACH Unaffected). The only difference is packaging format (Cut Tape vs. Tape & Box), which does not affect electrical or mechanical performance.

Q: What are the key differences between CMF551K0000FKEA and RNF12FAD1K00?

A: Both parts meet the core electrical requirements (1 kOhms ±1%, 0.5W, ±100ppm/°C) and are axial through-hole components with equivalent compliance. CMF551K0000FKEA offers an extended operating temperature range (-55°C to 175°C vs. -55°C to 155°C) and includes moisture resistance. Physical dimensions are smaller. These differences do not affect electrical substitution compatibility.

Q: Are there any mechanical compatibility concerns when substituting CMF551K0000FKEA?

A: CMF551K0000FKEA has smaller physical dimensions (0.090" Dia x 0.240" L) compared to RNF12FAD1K00 (0.108" Dia x 0.344" L). Both are axial through-hole packages with 2 terminations. PCB layout and spacing must accommodate the smaller component size. Electrical performance and pin compatibility remain unchanged.

Q: Do all substitute parts maintain RoHS3 and REACH compliance?

A: Yes. RNF12FTD1K00 and CMF551K0000FKEA are both ROHS3 Compliant and REACH Unaffected, matching the compliance status of RNF12FAD1K00.

Q: Which substitute should be selected for high-temperature applications?

A: CMF551K0000FKEA supports operating temperatures up to 175°C, compared to 155°C for RNF12FAD1K00. For applications requiring operation above 155°C, CMF551K0000FKEA is the appropriate selection.
