CMF601M0000FKBF Equivalent & Substitute Parts

Part Overview

The CMF601M0000FKBF is a 1 MOhms ±1% 1W through-hole axial resistor manufactured by Vishay Dale. This metal film resistor features flame retardant coating and moisture resistance, designed for applications requiring precision resistance values in compact axial packages. The part is currently active in production with 786 units in stock. Substitute parts are necessary to address packaging preferences, compliance requirements, or inventory availability across different distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMF601M0000FKBF is determined by matching the following critical parameters: resistance value (1 MOhms), tolerance (±1%), power rating (1W), composition (metal film), package type (axial), operating temperature range (-55°C ~ 175°C), and physical dimensions (0.145" Dia x 0.344" L). All identified substitute parts meet these core electrical and mechanical requirements. Variations in packaging format (bulk versus cut tape) and temperature coefficient do not affect functional interchangeability in circuit applications. Compliance status differences are noted for applications with specific regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

All three parts are active products from Vishay Dale with identical core electrical specifications. Selection between them depends on specific application requirements:

CMF601M0000FKBF is suitable for applications where bulk packaging is preferred and RoHS non-compliance is acceptable. This part offers standard temperature coefficient performance.

CMF601M0000FER6 provides improved temperature coefficient stability (±25ppm/°C versus ±100ppm/°C) and is available in cut tape packaging, supporting automated assembly processes. This part maintains RoHS non-compliant status consistent with the main part.

CMF601M0000FKEK is the appropriate selection for applications requiring ROHS3 compliance. It matches the main part's temperature coefficient specification and is available in bulk packaging. REACH compliance information is available upon request for this variant.

Frequently Asked Questions (FAQ)

Q: Can CMF601M0000FER6 be used as a direct replacement for CMF601M0000FKBF?

A: Yes. Both parts share identical resistance (1 MOhms), tolerance (±1%), power rating (1W), composition (metal film), package type (axial), operating temperature range (-55°C ~ 175°C), and physical dimensions. The primary differences are packaging format (cut tape versus bulk) and temperature coefficient (±25ppm/°C versus ±100ppm/°C). The improved temperature coefficient of CMF601M0000FER6 does not prevent substitution; it represents enhanced performance.

Q: What is the difference between bulk and cut tape packaging?

A: Bulk packaging is suitable for manual assembly and small-volume applications. Cut tape packaging is designed for automated pick-and-place assembly systems. Both formats contain identical components; packaging selection depends on assembly methodology.

Q: Is CMF601M0000FKEK compatible with applications requiring RoHS compliance?

A: Yes. CMF601M0000FKEK carries ROHS3 compliance certification, making it suitable for applications with RoHS requirements. The main part (CMF601M0000FKBF) and CMF601M0000FER6 are RoHS non-compliant and should not be used in applications with mandatory RoHS compliance.

Q: How does temperature coefficient affect part selection?

A: Temperature coefficient indicates resistance value drift across the operating temperature range. CMF601M0000FER6 has ±25ppm/°C, while CMF601M0000FKBF and CMF601M0000FKEK have ±100ppm/°C. Applications requiring tighter resistance stability across temperature variations should prioritize the lower temperature coefficient specification.

Q: Are all three parts manufactured by the same company?

A: Yes. All three parts are manufactured by Vishay Dale and belong to the CMF series. They share the same base product number (CMF60) and are produced to identical electrical specifications within their respective tolerance and temperature coefficient parameters.
