Ohmite 41F820 Equivalent & Substitute Parts

Part Overview

The Ohmite 41F820 is an 820 Ohms ±1% 1W through-hole resistor with axial wirewound construction, part of the Ohmicone® 40 series. This component is currently active in production with 974 units in stock. The 41F820 is RoHS non-compliant, which may necessitate identification of compliant alternatives for applications subject to RoHS regulations or procurement requirements mandating RoHS-compliant components.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 41F820 is determined by electrical and mechanical parameter equivalence. The substitute part must maintain identical specifications across resistance value (820 Ohms), tolerance (±1%), power rating (1W), composition (wirewound), package configuration (axial), temperature coefficient (±20ppm/°C), and physical dimensions (0.126" Dia x 0.437" L). The primary distinction between the main part and its substitute relates to packaging format and RoHS compliance status, not functional electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 41F820E serves as a direct electrical and mechanical substitute for the 41F820, with identical functional specifications across all critical parameters. The primary distinction is RoHS compliance: the 41F820E is ROHS3 compliant, while the 41F820 is RoHS non-compliant. Selection between these parts should be based on regulatory requirements and procurement specifications. Both parts are active products with adequate inventory availability. The 41F820E is supplied in bulk packaging, whereas the 41F820 uses standard packaging; this distinction affects only handling and logistics, not component performance.

Frequently Asked Questions (FAQ)

Q: Are the 41F820 and 41F820E electrically identical? A: Yes. Both parts have identical resistance (820 Ohms), tolerance (±1%), power rating (1W), temperature coefficient (±20ppm/°C), and wirewound composition. They are functionally equivalent in circuit applications.

Q: What is the difference between these two parts? A: The primary differences are RoHS compliance status and packaging format. The 41F820E is ROHS3 compliant and supplied in bulk packaging, while the 41F820 is RoHS non-compliant and uses standard packaging. These differences do not affect electrical performance.

Q: Can I use the 41F820E as a direct replacement for the 41F820? A: Yes, the 41F820E is a direct substitute. Physical dimensions, electrical characteristics, and mechanical specifications are identical, ensuring compatibility in existing circuit designs and PCB layouts.

Q: Why would I choose the 41F820E over the 41F820? A: Selection of the 41F820E is appropriate when RoHS compliance is required by design specifications, regulatory standards, or customer procurement requirements.

Q: Are there any compatibility concerns with the axial package configuration? A: No. Both parts use identical axial wirewound packaging with the same physical dimensions (0.126" Dia x 0.437" L). They are mechanically interchangeable in through-hole PCB applications.

Q: What is the temperature coefficient significance? A: Both parts have a temperature coefficient of ±20ppm/°C, indicating identical thermal stability. This specification ensures consistent resistance value across the operating temperature range.
