Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 83F10K is determined by strict equivalence across the following critical parameters:

• Resistance value: 10 kOhms
• Tolerance: ±1%
• Power rating: 3W
• Composition: Wirewound
• Package configuration: Axial through-hole
• Temperature coefficient: ±20ppm/°C
• Termination count: 2

The Ohmite 43F10K qualifies as a direct substitute based on complete alignment with all specified electrical parameters. Both components are manufactured by Ohmite, maintain identical resistance, tolerance, power rating, and temperature coefficient specifications. Physical dimensions vary minimally (diameter 0.220" vs 0.217"), which remains within acceptable mechanical tolerances for standard through-hole PCB applications. Both components share identical RoHS non-compliance status and REACH unaffected classification.

Parameter Comparison

Engineering Selection Recommendations

Both the 83F10K and 43F10K are Active products from Ohmite with identical electrical specifications and regulatory compliance profiles. Selection between these components should be based on availability and procurement requirements. The 43F10K is available in Bulk packaging, while the 83F10K packaging specification is not provided. Both components maintain RoHS non-compliant status and REACH unaffected classification, making them equivalent for applications where these regulatory statuses are acceptable. The minimal dimensional variance (0.003" diameter difference) does not impact standard through-hole PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 43F10K replace the 83F10K in existing designs?

A: Yes. Both components share identical electrical specifications: 10 kOhms resistance, ±1% tolerance, 3W power rating, ±20ppm/°C temperature coefficient, and wirewound axial construction. The 0.003" diameter difference does not affect standard PCB through-hole mounting.

Q: Are there differences in series designation between these parts?

A: The 83F10K belongs to the Acrasil® 80 series, while the 43F10K belongs to the Ohmicone® 40 series. Despite different series classifications, both meet identical electrical and mechanical parameters for this 10 kOhms 3W application.

Q: What is the significance of the packaging difference?

A: The 83F10K packaging is unspecified in available data, while the 43F10K is supplied in Bulk packaging. This distinction affects procurement and handling procedures but does not impact electrical or mechanical performance in the application.

Q: Do both parts comply with RoHS requirements?

A: Both the 83F10K and 43F10K are RoHS non-compliant. If RoHS compliance is required for your application, alternative component families must be evaluated.

Q: Are there any thermal performance differences between these substitutes?

A: No. Both components specify identical temperature coefficient of ±20ppm/°C, ensuring equivalent thermal stability across the operating range.
