Ohmite 40F6K0 6kΩ 10W Axial Wirewound Resistor - Equivalent & Substitute Parts

Part Overview

The Ohmite 40F6K0 is a 6 kOhms ±1% 10W through-hole resistor with axial wirewound construction, part of the Ohmicone® 40 series. This component is designed for applications requiring precision resistive elements with moderate power dissipation in compact axial packages. The part is currently active in production with 1009 units in stock. Substitute parts are identified when packaging configurations or compliance requirements differ while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the 40F6K0 is determined by the following critical parameters:

• Resistance Value: Must be 6 kOhms
• Tolerance: Must be ±1%
• Power Rating: Must be 10W
• Composition: Must be Wirewound
• Temperature Coefficient: Must be ±20ppm/°C
• Package Type: Must be Axial
• Physical Dimensions: Must be 0.406" Dia x 1.902" L (10.30mm x 48.30mm)
• Terminations: Must be 2

The identified substitute part 40F6K0E matches all electrical and mechanical parameters. The primary difference is packaging configuration (Bulk versus standard packaging) and RoHS compliance status, which do not affect functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 40F6K0 and 40F6K0E are active production parts from Ohmite with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

40F6K0: Select this part number when RoHS non-compliant components are acceptable for the application and standard packaging is required.

40F6K0E: Select this part number when ROHS3 compliance is mandated by design requirements or regulatory constraints. This variant is supplied in bulk packaging configuration.

Both parts are functionally equivalent in circuit operation and occupy identical physical space within PCB layouts or component assemblies.

Frequently Asked Questions (FAQ)

Q: Are the 40F6K0 and 40F6K0E electrically identical?

A: Yes. Both parts have identical resistance value (6 kOhms), tolerance (±1%), power rating (10W), temperature coefficient (±20ppm/°C), and wirewound composition. They will perform identically in circuit applications.

Q: What is the difference between these part numbers?

A: The primary differences are packaging configuration (Bulk for 40F6K0E) and RoHS compliance status (40F6K0E is ROHS3 compliant, while 40F6K0 is non-compliant). Electrical and mechanical specifications are identical.

Q: Can I substitute 40F6K0E for 40F6K0 in my design?

A: Yes, provided your application does not have specific packaging requirements that mandate the standard packaging of the 40F6K0. If RoHS3 compliance is required, 40F6K0E is the appropriate selection.

Q: Do these parts have the same physical dimensions?

A: Yes. Both parts measure 0.406" diameter by 1.902" length (10.30mm x 48.30mm) and are housed in identical axial packages with 2 terminations.

Q: What certifications apply to both parts?

A: Both parts carry EAR99 ECCN classification and HTSUS code 8533.21.0080. REACH status is REACH Unaffected for both variants. RoHS compliance differs: 40F6K0 is non-compliant, while 40F6K0E is ROHS3 compliant.
