Ohmite 41J150E Equivalent & Substitute Parts

Part Overview

The Ohmite 41J150E is a 150 Ohm, 1W through-hole axial wirewound resistor from the Ohmicone® 40 series. This component is classified as Active and remains in production. Substitute parts are identified when the original part becomes unavailable, when design requirements necessitate improved tolerance specifications, or when alternative packaging formats are required for manufacturing processes.

Substitute Part Grouping Explanation

Substitution of the 41J150E is permissible when the following core parameters remain constant:

• Resistance value: 150 Ohms (exact match required)
• Power rating: 1W (exact match required)
• Composition: Wirewound (exact match required)
• Package type: Axial (exact match required)
• Physical dimensions: 0.126" Dia x 0.437" L (exact match required)
• Temperature coefficient: ±20ppm/°C (exact match required)

Tolerance may be improved (tightened) from ±5% to ±1% without affecting circuit functionality, as this represents enhanced precision. RoHS compliance status may vary between substitute parts provided both meet applicable regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

The 41F150E serves as a direct substitute for the 41J150E based on electrical and mechanical equivalence. Both components are manufactured by Ohmite, belong to the Ohmicone® 40 series, and maintain Active product status.

The 41F150E offers improved tolerance specification (±1% versus ±5%), which provides enhanced precision for applications requiring tighter resistance values. Both parts maintain identical temperature coefficient, power rating, and physical dimensions, ensuring direct interchangeability in circuit board layouts and through-hole assembly processes.

Both parts satisfy RoHS compliance requirements. The 41F150E specifies an operating temperature range of -55°C to 275°C, whereas the 41J150E does not provide this specification in available documentation. Selection between these parts should be based on packaging requirements (Bulk versus Box) and tolerance precision needs for the specific application.

Frequently Asked Questions (FAQ)

Q: Can the 41F150E replace the 41J150E in existing designs?

A: Yes. The 41F150E is electrically and mechanically equivalent to the 41J150E. Both components share identical resistance value, power rating, temperature coefficient, composition, package type, and physical dimensions. The primary difference is improved tolerance specification in the 41F150E.

Q: What is the significance of the tolerance difference between ±5% and ±1%?

A: Tolerance defines the acceptable range of resistance variation from the nominal 150 Ohm value. The 41J150E permits variation between 142.5 and 157.5 Ohms. The 41F150E permits variation between 148.5 and 151.5 Ohms. Applications requiring precise resistance values benefit from the tighter tolerance of the 41F150E.

Q: Are there packaging differences between these parts?

A: Yes. The 41J150E is supplied in Bulk packaging, while the 41F150E is supplied in Box packaging. Both use identical axial through-hole package format with matching physical dimensions. Packaging selection depends on manufacturing and inventory requirements.

Q: Do both parts meet RoHS requirements?

A: Yes. The 41J150E is ROHS3 Compliant, and the 41F150E is RoHS Compliant. Both satisfy regulatory requirements for hazardous substance restrictions.

Q: What is the operating temperature range for these components?

A: The 41F150E specifies an operating temperature range of -55°C to 275°C. The 41J150E does not provide an explicit operating temperature range specification in available documentation. Both components maintain a temperature coefficient of ±20ppm/°C.
