Key Parameters

Substitute Part Grouping Explanation

Substitution for the Ohmite 43F820 is determined by strict equivalence across the following parameters:

• Resistance value: 820 Ohms
• Tolerance: ±1%
• Power rating: 3W
• Composition: Wirewound
• Temperature coefficient: ±20ppm/°C
• Package configuration: Axial
• Physical dimensions: 0.220" Dia x 0.594" L (5.60mm x 15.10mm)
• Number of terminations: 2

The identified substitute, Ohmite 43F820E, maintains identical electrical and mechanical specifications while differing in packaging format and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The Ohmite 43F820E serves as a direct parametric equivalent to the 43F820, with identical electrical performance and mechanical compatibility. The primary distinction is RoHS3 compliance status of the 43F820E, which qualifies it for applications requiring regulatory adherence to RoHS directives. Both parts maintain active production status and are available in inventory. Selection between these parts should be based on regulatory requirements and packaging format needs (standard versus bulk).

Frequently Asked Questions (FAQ)

Q: Are the 43F820 and 43F820E electrically interchangeable?

A: Yes. Both parts specify identical resistance (820 Ohms), tolerance (±1%), power rating (3W), temperature coefficient (±20ppm/°C), and wirewound composition. They are direct electrical equivalents.

Q: What is the difference between the 43F820 and 43F820E?

A: The primary differences are packaging format (standard versus bulk) and RoHS compliance status. The 43F820E is ROHS3 compliant, while the 43F820 is RoHS non-compliant. All electrical and mechanical parameters are identical.

Q: Can the 43F820E be used as a drop-in replacement for the 43F820?

A: Yes. The parts share identical physical dimensions (0.220" Dia x 0.594" L), axial package configuration, and two-terminal design. PCB layout and mechanical mounting are compatible.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications subject to RoHS directives, the 43F820E is the appropriate choice. For applications without RoHS requirements, either part is suitable based on availability and packaging preference.

Q: Are there any performance differences between these parts?

A: No. Both parts maintain identical temperature coefficient (±20ppm/°C), tolerance (±1%), and power handling characteristics (3W).
