Key Parameters

Substitute Part Grouping Explanation

The Ohmite 45F2K0E qualifies as a parametric equivalent to the 85F2K0 based on the following critical parameters:

• Identical resistance value: 2 kOhms
• Matching tolerance: ±1%
• Equivalent power rating: 5W
• Same composition: Wirewound
• Identical package configuration: Axial
• Matching temperature coefficient: ±20ppm/°C
• Identical physical dimensions: 0.343" Dia x 0.937" L (8.70mm x 23.80mm)
• Same number of terminations: 2

Both parts share the same electrical performance specifications and mechanical form factor, making them functionally interchangeable in circuit applications requiring these parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the 85F2K0 and 45F2K0E are Active status components suitable for direct substitution based on electrical and mechanical parameters. The primary differentiation factor is RoHS compliance status: the 45F2K0E meets ROHS3 compliance requirements, while the 85F2K0 is RoHS non-compliant. Selection between these parts should be determined by the specific regulatory and compliance requirements of the end application. The 45F2K0E offers higher inventory availability at 3322 units compared to 1003 units for the 85F2K0.

Frequently Asked Questions (FAQ)

Q: Can the 45F2K0E be used as a direct replacement for the 85F2K0?

A: Yes. Both parts share identical electrical specifications (2 kOhms, ±1%, 5W, ±20ppm/°C) and mechanical form factor (Axial, 0.343" Dia x 0.937" L). They are functionally interchangeable in circuit applications.

Q: What is the difference between the Acrasil® 80 and Ohmicone® 40 series?

A: Both are Ohmite wirewound resistor series with identical electrical and mechanical parameters for this 2 kOhm 5W specification. The primary difference is RoHS compliance status: Ohmicone® 40 (45F2K0E) is ROHS3 compliant, while Acrasil® 80 (85F2K0) is RoHS non-compliant.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance status reflects manufacturing and material composition standards but does not alter the electrical performance characteristics of the resistor.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical dimensions of 0.343" Dia x 0.937" L (8.70mm x 23.80mm) and are suitable for the same PCB layouts and mechanical assemblies.

Q: Which part should I select for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance, specify the 45F2K0E. For applications without RoHS compliance requirements, either part is suitable based on availability and supply chain considerations.
