Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMF55900K00BEEK is determined by the following critical parameters:

• Resistance value: 900 kOhms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Composition: Metal Film (exact match required)
• Temperature coefficient: ±25ppm/°C (exact match required)
• Operating temperature range: -55°C to 175°C (exact match required)
• Package configuration: Axial through-hole (exact match required)
• Physical dimensions: 0.090" Dia × 0.240" L (exact match required)

The CMF55900K00BEBF qualifies as a parametric equivalent based on identical electrical and mechanical specifications across all critical parameters. Differences in RoHS compliance status do not affect functional substitutability for applications where RoHS3 compliance is not mandated.

Parameter Comparison

Engineering Selection Recommendations

The CMF55900K00BEBF serves as a direct parametric equivalent to the CMF55900K00BEEK for applications where RoHS3 compliance is not a contractual or regulatory requirement. Both parts are manufactured by Vishay Dale within the CMF series and maintain identical electrical performance characteristics, temperature stability, and physical form factor.

Selection between these parts should be based on:

• RoHS3 compliance mandate: If required, use CMF55900K00BEEK
• RoHS3 compliance not required: Either part is functionally equivalent; CMF55900K00BEBF offers higher current inventory availability (1581 units vs. 984 units)
• Supply chain continuity: Evaluate inventory levels and lead times for your procurement timeline

Both parts carry REACH Affected status and EAR99 ECCN classification with identical HTSUS coding (8533.21.0090).

Frequently Asked Questions (FAQ)

Q: Can CMF55900K00BEBF be used as a direct replacement for CMF55900K00BEEK in all applications?

A: Yes, for applications where RoHS3 compliance is not mandated. All electrical parameters, mechanical dimensions, and performance characteristics are identical. The only difference is RoHS compliance status.

Q: What is the significance of the different RoHS compliance levels?

A: CMF55900K00BEEK is ROHS3 compliant, meeting the latest RoHS Directive requirements. CMF55900K00BEBF is RoHS non-compliant. Selection depends on your end-use application's regulatory requirements. If your product must meet RoHS3 standards, use CMF55900K00BEEK.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts measure 0.090" diameter × 0.240" length (2.29mm × 6.10mm) and use identical axial through-hole package configuration. They are mechanically interchangeable on PCBs.

Q: Do these parts have the same temperature performance?

A: Yes. Both parts operate across -55°C to 175°C with ±25ppm/°C temperature coefficient, ensuring identical thermal stability in your circuit design.

Q: What inventory considerations should influence my selection?

A: CMF55900K00BEBF has higher current stock (1581 units) compared to CMF55900K00BEEK (984 units). If supply availability is a concern and RoHS3 compliance is not required, the BEBF variant offers better stock position.

Q: Are there any differences in moisture sensitivity or environmental protection?

A: No. Both parts feature identical flame retardant coating and moisture resistance properties, providing equivalent environmental protection for your application.
