Substitute Part Grouping Explanation

The CMF5519K600FHEB qualifies as a direct substitute for the CMF5519K600FKBF based on the following matching parameters:

• Identical resistance value: 19.6 kOhms
• 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 x 0.240" L (2.29mm x 6.10mm)
• Identical features: Flame Retardant Coating, Moisture Resistant, Safety

The primary difference between these parts is packaging format (Bulk versus Cut Tape/Tape & Reel) and temperature coefficient specification (±100ppm/°C versus ±50ppm/°C). Both parts belong to the CMF series and maintain electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain identical electrical and mechanical specifications for resistance, tolerance, power rating, and operating temperature range. Selection between CMF5519K600FKBF and CMF5519K600FHEB should be based on:

Compliance Requirements: The CMF5519K600FHEB offers ROHS3 compliance and REACH unaffected status, making it suitable for applications requiring regulatory adherence. The CMF5519K600FKBF is RoHS non-compliant and REACH affected.

Packaging Considerations: The CMF5519K600FKBF is supplied in Bulk packaging, while CMF5519K600FHEB is available in Cut Tape and Tape & Reel formats. Selection depends on assembly process requirements and volume handling procedures.

Temperature Coefficient: The CMF5519K600FHEB provides superior temperature stability at ±50ppm/°C compared to ±100ppm/°C for the CMF5519K600FKBF. Applications requiring tighter temperature coefficient performance should specify the substitute part.

Inventory Availability: CMF5519K600FHEB maintains higher stock levels (2814 units) compared to CMF5519K600FKBF (832 units).

Frequently Asked Questions (FAQ)

Q: Are CMF5519K600FKBF and CMF5519K600FHEB electrically interchangeable?

A: Yes. Both parts share identical resistance (19.6 kOhms), tolerance (±1%), power rating (0.5W), composition (metal film), and operating temperature range (-55°C to 175°C). They are electrically interchangeable in circuit applications.

Q: What is the difference in temperature coefficient between these parts?

A: The CMF5519K600FKBF has a temperature coefficient of ±100ppm/°C, while the CMF5519K600FHEB has ±50ppm/°C. The substitute part offers superior temperature stability.

Q: Can I use CMF5519K600FHEB in place of CMF5519K600FKBF in my assembly process?

A: Mechanical compatibility is confirmed; both use identical axial package dimensions (0.090" Dia x 0.240" L). However, packaging format differs: CMF5519K600FKBF is Bulk while CMF5519K600FHEB is Cut Tape or Tape & Reel. Verify your assembly equipment compatibility with the tape format before substitution.

Q: Which part should I specify for new designs?

A: Selection depends on regulatory requirements. For RoHS3 and REACH compliance, specify CMF5519K600FHEB. For applications without compliance constraints, either part is suitable based on packaging and inventory availability.

Q: Are there any mechanical differences between these parts?

A: No. Both parts have identical physical dimensions, termination count (2), and axial package configuration. They are mechanically interchangeable.
