Key Parameters

Substitute Part Grouping Explanation

The Ohmite 41F3K0E qualifies as a direct substitute based on identical electrical and mechanical parameters: 3 kOhms resistance, ±1% tolerance, 1W power rating, wirewound composition, axial package configuration, ±20ppm/°C temperature coefficient, and matching physical dimensions of 0.126" Dia x 0.437" L. The primary distinction between these parts is packaging format and compliance certification status. The 41F3K0E is supplied in bulk packaging and carries RoHS Compliant certification with MSL 1 (Unlimited) rating, whereas the 41F3K0 is RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

Selection between 41F3K0 and 41F3K0E depends on regulatory and compliance requirements. The 41F3K0E is the appropriate choice for applications requiring RoHS compliance certification. Both parts maintain identical electrical performance and mechanical compatibility. The 41F3K0E provides an explicit operating temperature range of -55°C ~ 275°C, whereas the 41F3K0 does not specify this parameter. Packaging format differs between the two parts: 41F3K0 uses standard packaging while 41F3K0E is supplied in bulk format. Both parts carry Active product status and are manufactured by Ohmite.

Frequently Asked Questions (FAQ)

Q: Are 41F3K0 and 41F3K0E electrically identical? A: Yes. Both parts have identical resistance value (3 kOhms), tolerance (±1%), power rating (1W), composition (wirewound), temperature coefficient (±20ppm/°C), and physical dimensions (0.126" Dia x 0.437" L).

Q: What is the primary difference between these parts? A: The 41F3K0E is RoHS Compliant with an explicit operating temperature range (-55°C ~ 275°C) and bulk packaging, while the 41F3K0 is RoHS non-compliant with standard packaging and no specified operating temperature range.

Q: Can I use 41F3K0E as a direct replacement for 41F3K0? A: Yes, from an electrical and mechanical standpoint. The substitution is valid for applications where RoHS compliance is not a constraint. For RoHS-regulated applications, 41F3K0E is the required choice.

Q: Does packaging format affect circuit performance? A: No. Packaging format (standard vs. bulk) does not affect electrical performance or mechanical fit. The difference is in procurement and handling logistics.

Q: Are both parts currently available? A: Yes. 41F3K0 has 845 pieces in stock and 41F3K0E has 827 pieces in stock.
