Substitute Part Grouping Explanation

Substitute parts for the CMF5510M000FKBF70 are classified based on strict electrical and mechanical parameter matching:

Direct Manufacturer Substitutes maintain identical electrical specifications (10 MOhms, ±1% tolerance, 0.5W power rating, ±100ppm/°C temperature coefficient, -55°C to 175°C operating range) and mechanical form factor (axial, 0.090" Dia x 0.240" L). Differences are limited to packaging format (Bulk versus Cut Tape) and manufacturing date codes, which do not affect functional performance or circuit compatibility.

Parametric Equivalents share all critical electrical parameters and physical dimensions with the main part. These parts are sourced from the same manufacturer series (CMF) and maintain identical resistance value, tolerance, power rating, temperature characteristics, and operating temperature range. Packaging variations and part status differences do not impact electrical interchangeability in circuit applications.

The key parameters determining substitution eligibility are: Resistance (10 MOhms), Tolerance (±1%), Power Rating (0.5W), Composition (Metal Film), Temperature Coefficient (±100ppm/°C), Operating Temperature Range (-55°C to 175°C), and Package Type (Axial).

Parameter Comparison

Engineering Selection Recommendations

CMF5510M000FKR6 is the preferred direct substitute when Cut Tape packaging is acceptable for automated assembly or tape-and-reel handling. This part maintains full electrical and mechanical equivalence with higher current inventory availability (1402 pieces).

CMF5510M000FKBF is the recommended parametric equivalent for Bulk packaging applications. It provides identical electrical performance and is actively produced with substantial inventory (1071 pieces).

CMF5510M000FKEK is available as a parametric equivalent but carries discontinued status at DiGi Electronics. Selection of this part should be evaluated based on long-term supply chain requirements and alternative sourcing confirmation.

All substitute parts comply with the same RoHS non-compliant status, REACH affected classification, and ECCN/HTSUS coding as the main part. Selection should prioritize active production status parts (CMF5510M000FKR6 or CMF5510M000FKBF) for new designs and ongoing production requirements.

Frequently Asked Questions (FAQ)

Q: Can CMF5510M000FKR6 be used as a direct replacement for CMF5510M000FKBF70?

A: Yes. Both parts share identical electrical specifications (10 MOhms, ±1% tolerance, 0.5W power rating, ±100ppm/°C temperature coefficient, -55°C to 175°C operating range) and mechanical dimensions (0.090" Dia x 0.240" L axial package). The only difference is packaging format: CMF5510M000FKR6 is supplied in Cut Tape format while CMF5510M000FKBF70 is supplied in Bulk. Circuit performance and reliability are equivalent.

Q: What is the difference between Bulk and Cut Tape packaging?

A: Bulk packaging supplies loose components suitable for manual assembly or tube feeding. Cut Tape packaging provides components on continuous tape with carrier, optimized for automated pick-and-place assembly equipment. Electrical and mechanical specifications are identical; packaging selection depends on assembly process requirements.

Q: Is CMF5510M000FKEK suitable for new production designs?

A: CMF5510M000FKEK is discontinued at DiGi Electronics. While inventory is available (1083 pieces), this part should not be selected for new production designs. Use CMF5510M000FKR6 or CMF5510M000FKBF instead, both of which maintain active production status.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All listed substitute parts share identical RoHS non-compliant status, REACH affected classification, ECCN (EAR99), and HTSUS (8533.21.0090) coding as the main part CMF5510M000FKBF70.

Q: Can these parts be used interchangeably in existing circuit designs?

A: Yes. All substitute parts maintain identical electrical parameters (resistance, tolerance, power rating, temperature coefficient, operating temperature range) and physical form factor (axial through-hole). No circuit redesign or re-qualification is required for substitution.
