CMF071K2000GKBF Equivalent & Substitute Parts

Part Overview

The CMF071K2000GKBF is a 1.2 kOhms ±2% metal film through-hole resistor rated at 0.5W (1/2W) in axial package configuration. Manufactured by Vishay Dale, this component features flame retardant coating and moisture resistance suitable for industrial and commercial applications. The part maintains Active product status with 925 units currently in stock.

Identifying equivalent and substitute parts becomes necessary when the original part reaches end-of-life status, inventory constraints occur, or design requirements demand improved performance specifications such as tighter tolerance ratings.

Substitute Part Grouping Explanation

Substitution eligibility for the CMF071K2000GKBF is determined by the following critical parameters:

Primary Substitution Criteria:

  • Resistance value: 1.2 kOhms (exact match required)
  • Power rating: 0.5W minimum
  • Package type: Axial configuration
  • Composition: Metal film construction
  • Operating temperature range: -55°C to 175°C minimum
  • Physical dimensions: 0.090" Dia x 0.240" L

Secondary Compatibility Parameters:

  • Tolerance: ±2% or tighter (±1% acceptable as upgrade)
  • Temperature coefficient: ±100ppm/°C or better
  • Features: Flame retardant coating and moisture resistance

The CMF551K2000FKR6 qualifies as a direct substitute by meeting all primary criteria while offering improved tolerance specification (±1% versus ±2%), representing an upgrade path within the same product family.

Engineering Selection Recommendations

Both the CMF071K2000GKBF and CMF551K2000FKR6 maintain Active product status from Vishay Dale, ensuring continued availability and manufacturing support. The substitute part CMF551K2000FKR6 provides identical electrical and mechanical performance with the advantage of ±1% tolerance specification compared to the ±2% tolerance of the main part.

Compliance considerations remain consistent between both parts: both are RoHS non-compliant and REACH Affected. Selection between these parts should be based on tolerance requirements specific to the application circuit. Applications requiring tighter tolerance control benefit from the CMF551K2000FKR6 upgrade, while applications within ±2% tolerance specifications accept either part.

Packaging format differs between parts: CMF071K2000GKBF is supplied in Bulk packaging, while CMF551K2000FKR6 is supplied in Cut Tape (CT) format. This distinction affects procurement and assembly processes but does not impact electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can CMF551K2000FKR6 directly replace CMF071K2000GKBF in existing designs?

A: Yes. Both parts share identical resistance value (1.2 kOhms), power rating (0.5W), axial package configuration, physical dimensions (0.090" Dia x 0.240" L), operating temperature range (-55°C to 175°C), and core features (flame retardant coating, moisture resistance). The substitute offers improved tolerance (±1% versus ±2%), making it functionally compatible in all applications.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution requires matching resistance value, power rating, package type (axial), composition (metal film), and physical dimensions. Tolerance may be equal or tighter. Operating temperature range and temperature coefficient must meet or exceed the original specification.

Q: Does the packaging format (Bulk versus Cut Tape) affect electrical performance?

A: No. Packaging format affects procurement, storage, and assembly logistics only. Electrical and mechanical characteristics remain identical regardless of packaging type.

Q: Are both parts suitable for applications requiring RoHS compliance?

A: No. Both CMF071K2000GKBF and CMF551K2000FKR6 are RoHS non-compliant. Applications requiring RoHS-compliant components require alternative part selection outside this substitution group.

Q: What is the tolerance difference between these parts, and when does it matter?

A: CMF071K2000GKBF carries ±2% tolerance while CMF551K2000FKR6 carries ±1% tolerance. The tighter tolerance of the substitute becomes critical in precision circuits where resistor value accuracy directly affects circuit performance, such as precision amplifier feedback networks or analog-to-digital converter reference circuits.
