Substitute Part Grouping Explanation

Substitution eligibility for the CMF551K2000FKBF is determined by strict equivalence across the following critical parameters:

• Resistance Value: 1.2 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.5W / 1/2W (exact match required)
• Composition: Metal Film (exact match required)
• Package Configuration: Axial through-hole (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 175°C (exact match required)
• Physical Dimensions: 0.090" Dia x 0.240" L / 2.29mm x 6.10mm (exact match required)

The identified substitute part differs only in packaging format (Cut Tape versus Bulk), which does not affect electrical or mechanical performance. Both parts are manufactured by Vishay Dale within the CMF series and maintain identical functional specifications.

Parameter Comparison

Engineering Selection Recommendations

Both CMF551K2000FKBF and CMF551K2000FKR6 are active production parts manufactured by Vishay Dale with identical electrical and mechanical specifications. Selection between these parts is determined by packaging requirements and supply chain considerations:

CMF551K2000FKBF is specified when bulk packaging is required for high-volume manufacturing or inventory consolidation applications.

CMF551K2000FKR6 is specified when cut tape packaging is required for automated pick-and-place assembly processes or when smaller quantity procurement is necessary. This substitute part maintains 10425 pieces in current inventory, providing enhanced availability compared to the bulk-packaged variant.

Both parts are active in production status and suitable for direct substitution in applications requiring 1.2 kOhms ±1% metal film resistors with 0.5W power rating and axial through-hole configuration.

Frequently Asked Questions (FAQ)

Q: Can CMF551K2000FKR6 be used as a direct replacement for CMF551K2000FKBF?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: CMF551K2000FKBF is supplied in bulk packaging, while CMF551K2000FKR6 is supplied in cut tape format. Both are suitable for identical circuit applications.

Q: What is the difference between bulk and cut tape packaging?

A: Bulk packaging supplies loose components in a container, suitable for manual assembly or high-volume bin storage. Cut tape packaging supplies components on continuous tape in specified quantities, optimized for automated assembly equipment and pick-and-place machines.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts measure 0.090" diameter by 0.240" length (2.29mm x 6.10mm). They are mechanically interchangeable in all through-hole PCB applications.

Q: Do both parts have the same electrical specifications?

A: Yes. Both parts are 1.2 kOhms ±1% metal film resistors rated at 0.5W with ±100ppm/°C temperature coefficient and -55°C to 175°C operating temperature range.

Q: Which part should be selected for automated assembly?

A: CMF551K2000FKR6 in cut tape packaging is optimized for automated pick-and-place assembly processes.

Q: Which part should be selected for manual assembly or stock consolidation?

A: CMF551K2000FKBF in bulk packaging is suitable for manual assembly operations and centralized component inventory management.

Q: Are both parts currently in production?

A: Yes. Both CMF551K2000FKBF and CMF551K2000FKR6 are active production parts from Vishay Dale.
