Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMF705M0000FKBF is determined by the following critical parameters:

• Resistance value: 5 MOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Composition: Metal Film (exact match required)
• Package: Axial (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 175°C (exact match required)
• Features: Flame Retardant Coating, Moisture Resistant, Safety (exact match required)
• Terminations: 2 (exact match required)

The CMF605M0000FKBF qualifies as a substitute based on matching all critical electrical and mechanical parameters. The primary difference is the power rating reduction from 1.75W to 1W, which represents a derating that may be acceptable depending on circuit power dissipation requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the CMF705M0000FKBF and CMF605M0000FKBF maintain Active product status and identical compliance profiles (RoHS non-compliant, REACH Affected, ECCN EAR99). Selection between these parts depends on circuit power dissipation requirements:

• Use CMF705M0000FKBF when circuit design requires the full 1.75W power rating capability.
• Use CMF605M0000FKBF when circuit power dissipation does not exceed 1W, offering higher inventory availability (3859 units versus 1142 units).

Both parts are manufactured by Vishay Dale within the same CMF series and share identical electrical characteristics (5 MOhms, ±1% tolerance, ±100ppm/°C temperature coefficient, -55°C to 175°C operating range). Physical dimensions differ due to power rating differences; verify PCB layout compatibility before substitution.

Frequently Asked Questions (FAQ)

Q: Can CMF605M0000FKBF replace CMF705M0000FKBF in all applications?

A: Substitution is valid only when circuit power dissipation remains below 1W. If the design requires power handling above 1W, the CMF705M0000FKBF must be used.

Q: Are the electrical specifications identical between these parts?

A: Yes. Both parts share identical resistance (5 MOhms), tolerance (±1%), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 175°C). The only difference is power rating.

Q: Do the physical dimensions differ?

A: Yes. The CMF705M0000FKBF measures 0.180" Dia x 0.562" L (4.57mm x 14.27mm), while the CMF605M0000FKBF measures 0.145" Dia x 0.344" L (3.68mm x 8.74mm). Verify PCB footprint and layout clearances before substitution.

Q: Are compliance certifications the same?

A: Yes. Both parts share identical RoHS non-compliant status, REACH Affected designation, and ECCN EAR99 classification.

Q: Which part should be selected for new designs?

A: Select based on actual circuit power dissipation requirements. If power dissipation is confirmed below 1W, the CMF605M0000FKBF is acceptable and offers superior inventory availability.
