Substitute Part Grouping Explanation

Substitution of the CMF605M0000GKBF is based on strict electrical and mechanical parameter matching. The primary substitute identified is the CMF605M0000FKBF, which maintains identical specifications across all critical parameters with the exception of tolerance. Both parts share the same resistance value (5 MOhms), power rating (1W), composition (metal film), package type (axial), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 175°C), physical dimensions (0.145" Dia x 0.344" L), and series designation (CMF). The key differentiator is tolerance: the CMF605M0000GKBF provides ±2% tolerance, while the CMF605M0000FKBF provides ±1% tolerance. This tighter tolerance in the substitute part represents an upgrade in precision capability without any compromise to other electrical or mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the CMF605M0000GKBF and CMF605M0000FKBF are active products from Vishay Dale with identical RoHS non-compliance status and REACH affected classification. Selection between these parts should be based on tolerance requirements specific to the application circuit. The CMF605M0000GKBF is suitable for applications where ±2% tolerance meets design specifications. The CMF605M0000FKBF provides tighter tolerance control at ±1%, making it appropriate for precision circuits requiring reduced resistance variation. Both parts maintain identical thermal characteristics, mechanical compatibility, and environmental protection features. Inventory availability of the CMF605M0000FKBF (3859 units) exceeds that of the CMF605M0000GKBF (1085 units), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can the CMF605M0000FKBF directly replace the CMF605M0000GKBF in existing designs?

A: Yes. Both parts are mechanically and electrically compatible. They share identical resistance values, power ratings, package types, physical dimensions, and operating temperature ranges. The substitute part features improved tolerance (±1% versus ±2%), which represents a performance upgrade with no degradation in any parameter.

Q: What is the primary difference between these two resistors?

A: The tolerance specification differs. The CMF605M0000GKBF provides ±2% tolerance, while the CMF605M0000FKBF provides ±1% tolerance. All other electrical and mechanical parameters are identical.

Q: Are both parts suitable for the same temperature range?

A: Yes. Both the CMF605M0000GKBF and CMF605M0000FKBF operate across the identical temperature range of -55°C to 175°C with the same temperature coefficient of ±100ppm/°C.

Q: Do these parts require different PCB footprints?

A: No. Both resistors share identical physical dimensions (0.145" Dia x 0.344" L / 3.68mm x 8.74mm) and axial package configuration, requiring no PCB layout modifications for substitution.

Q: Which part should be selected for precision applications?

A: The CMF605M0000FKBF is the appropriate choice for applications requiring tighter tolerance control, as it provides ±1% tolerance compared to the ±2% tolerance of the CMF605M0000GKBF.
