Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMF652M0000FKBF is determined by the following critical parameters:

• Resistance Value: Must be 2 MOhms
• Tolerance: Must be ±1%
• Composition: Must be Metal Film
• Temperature Coefficient: Must be ±100ppm/°C
• Operating Temperature Range: Must support -55°C ~ 175°C
• Package Type: Must be Axial
• Series: CMF series designation

The CMF602M0000FKBF qualifies as a substitute part because it maintains identical electrical specifications (resistance, tolerance, composition, temperature coefficient, and operating range) and package configuration. The primary difference is the power rating reduction from 1.5W to 1W, which represents a design trade-off in physical size while preserving all other functional parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the CMF652M0000FKBF and CMF602M0000FKBF maintain Active product status with current manufacturer support. Selection between these parts depends on circuit power dissipation requirements:

• CMF652M0000FKBF: Select when circuit design requires 1.5W power handling capacity or when physical space permits the larger axial package (0.180" diameter x 0.562" length).

• CMF602M0000FKBF: Select when circuit design operates within 1W power dissipation limits and when space constraints favor the smaller axial package (0.145" diameter x 0.344" length).

Both parts share identical compliance status (RoHS non-compliant, REACH Affected) and regulatory classifications (ECCN: EAR99, HTSUS: 8533.21.0090). Electrical performance characteristics remain equivalent across the full operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can CMF602M0000FKBF replace CMF652M0000FKBF in all applications?

A: Substitution is valid only when circuit power dissipation does not exceed 1W. If the design requires 1.5W power handling, the CMF602M0000FKBF is not suitable.

Q: What is the primary difference between these two parts?

A: The power rating differs (1.5W versus 1W), resulting in different physical dimensions. All electrical specifications remain identical.

Q: Are the axial packages mechanically compatible?

A: Both use axial package configuration with two terminations. However, physical dimensions differ: CMF652M0000FKBF measures 0.180" diameter x 0.562" length, while CMF602M0000FKBF measures 0.145" diameter x 0.344" length. PCB layout and mechanical clearance must accommodate the selected package size.

Q: Do these parts have identical temperature performance?

A: Yes. Both parts operate across -55°C to 175°C with ±100ppm/°C temperature coefficient, ensuring equivalent thermal stability.

Q: Are there compliance differences between these substitutes?

A: No. Both parts share identical RoHS non-compliant and REACH Affected status, with matching ECCN and HTSUS classifications.
