Substitute Part Grouping Explanation

Substitution between CMF551M3000FKBF and CMF551M3000FHEB is based on the following allowed parameters:

• Resistance value: 1.3 MOhms (identical)
• Tolerance: ±1% (identical)
• Power rating: 0.5W / 1/2W (identical)
• Composition: Metal Film (identical)
• Package type: Axial (identical)
• Operating temperature range: -55°C to 175°C (identical)
• Physical dimensions: 0.090" Dia × 0.240" L (identical)
• Number of terminations: 2 (identical)
• Series: CMF (identical)
• Manufacturer: Vishay Dale (identical)

The primary distinction between these parts is packaging format (Bulk versus Cut Tape) and compliance certifications. Both parts meet the core electrical and mechanical requirements for direct substitution in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both CMF551M3000FKBF and CMF551M3000FHEB are electrically and mechanically equivalent for circuit applications requiring 1.3 MOhms ±1% metal film resistors at 0.5W power rating in axial package configuration.

CMF551M3000FKBF is suitable for applications where RoHS non-compliance and REACH-affected status are acceptable within the design and regulatory framework.

CMF551M3000FHEB is the appropriate selection for applications requiring ROHS3 compliance and REACH unaffected status. This part also provides improved temperature coefficient performance at ±50ppm/°C compared to ±100ppm/°C of the primary part. The Cut Tape packaging format supports automated assembly processes.

Selection between these parts should be based on compliance requirements, packaging format compatibility with assembly equipment, and temperature stability specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Can CMF551M3000FHEB replace CMF551M3000FKBF in existing designs?

A: Yes. Both parts share identical electrical specifications (1.3 MOhms ±1%, 0.5W metal film), identical physical dimensions (0.090" Dia × 0.240" L), and identical axial package configuration. Direct substitution is supported at the circuit level.

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

A: Bulk packaging supplies components in loose form suitable for manual assembly or bin storage. Cut Tape packaging supplies components on continuous tape with individual component spacing, optimized for automated pick-and-place assembly equipment. Both formats contain identical components.

Q: Does the temperature coefficient difference affect substitution?

A: The CMF551M3000FHEB provides superior temperature stability at ±50ppm/°C versus ±100ppm/°C for CMF551M3000FKBF. Both operate across the identical temperature range (-55°C to 175°C). Selection depends on circuit tolerance requirements for resistance drift over temperature.

Q: What compliance differences exist between these parts?

A: CMF551M3000FKBF is RoHS non-compliant and REACH Affected. CMF551M3000FHEB is ROHS3 Compliant and REACH Unaffected. Applications subject to RoHS3 or REACH regulations must use CMF551M3000FHEB.

Q: Are both parts currently available?

A: Both parts maintain Active product status. CMF551M3000FKBF has 970 pieces in stock. CMF551M3000FHEB has 1219 pieces in stock.
