Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMF555K3000BEEK is determined by the following critical parameters:

• Resistance value: 5.3 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 (exact match required)
• Physical dimensions: 0.090" Dia × 0.240" L (exact match required)
• Termination count: 2 (exact match required)

The identified substitute part CMF555K3000BEEB matches all electrical and mechanical parameters. The primary difference is packaging format: the main part is supplied in Bulk packaging, while the substitute is supplied in Cut Tape (CT) format. Both parts are from the same CMF series and manufacturer.

Parameter Comparison

Engineering Selection Recommendations

Both CMF555K3000BEEK and CMF555K3000BEEB are Active products from Vishay Dale and maintain identical electrical and mechanical specifications. Selection between these parts is determined by packaging requirements and supply chain considerations:

• CMF555K3000BEEK (Bulk packaging) is suitable for high-volume manufacturing environments with automated handling systems.
• CMF555K3000BEEB (Cut Tape packaging) is suitable for lower-volume applications, kit assembly, or manual component placement.

Both parts are ROHS3 Compliant and meet the same regulatory requirements. The choice between them does not affect circuit performance or reliability characteristics.

Frequently Asked Questions (FAQ)

Q: Can CMF555K3000BEEB be used as a direct replacement for CMF555K3000BEEK?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Bulk versus Cut Tape). Functional performance in the circuit is identical.

Q: Does packaging format affect component performance?

A: No. Packaging format affects only handling, storage, and assembly processes. Electrical characteristics, tolerance, temperature coefficient, and operating range are identical between the two parts.

Q: Are there any compliance differences between these parts?

A: No. Both parts carry identical RoHS3 Compliance status and meet the same regulatory standards.

Q: What is the significance of the ±0.1% tolerance specification?

A: The ±0.1% tolerance indicates precision-grade resistors suitable for applications requiring tight resistance accuracy. This tolerance applies to both the main part and substitute part.

Q: Can these axial resistors be used in automated assembly?

A: Yes. Both Bulk and Cut Tape packaging formats are compatible with standard through-hole assembly equipment. Cut Tape format is optimized for automated tape-fed systems, while Bulk format is suitable for manual or vibratory feeder systems.
