Key Parameters

Substitute Part Grouping Explanation

Substitution for the CMF604K7500FKBF is determined by strict equivalence across the following critical parameters:

• Resistance value: 4.75 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Composition: Metal Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 175°C
• Package type: Axial
• Physical dimensions: 0.145" Dia x 0.344" L
• Number of terminations: 2
• Features: Flame Retardant Coating, Moisture Resistant, Safety

The CMF604K7500FKEK meets all these parameters and is classified as a parametric equivalent. Both parts belong to the Vishay Dale CMF series and share identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The CMF604K7500FKBF is the preferred selection for new designs due to its active product status and current availability. The CMF604K7500FKEK is electrically and mechanically identical but is discontinued at DiGi Electronics, making it suitable only for replacement or maintenance applications where existing inventory exists.

Both parts are RoHS non-compliant and REACH Affected. Selection between these parts should be based on availability and project timeline requirements rather than electrical performance, as they are parametric equivalents.

Frequently Asked Questions (FAQ)

Q: Can CMF604K7500FKEK be used as a direct replacement for CMF604K7500FKBF?

A: Yes. Both parts are parametric equivalents with identical resistance, tolerance, power rating, temperature coefficient, operating temperature range, and physical dimensions. The only difference is product status; CMF604K7500FKBF is active while CMF604K7500FKEK is discontinued at DiGi Electronics.

Q: What determines if a part can substitute for the CMF604K7500FKBF?

A: A substitute must match all critical parameters: 4.75 kOhms resistance, ±1% tolerance, 1W power rating, metal film composition, ±100ppm/°C temperature coefficient, -55°C to 175°C operating range, axial package type, and 0.145" Dia x 0.344" L dimensions.

Q: Are there any compliance differences between these parts?

A: Both parts share identical RoHS and REACH status. Neither part is RoHS compliant, and both are REACH Affected.

Q: Which part should be selected for new production designs?

A: CMF604K7500FKBF should be selected for new designs due to its active product status and ongoing availability.
