F10J150E Equivalent & Substitute Parts

Part Overview

The F10J150E is a 150 Ohms ±5% 10W wirewound chassis mount resistor manufactured by Ohmite, part of the Stackohm® 250 series. This component is actively produced and widely used in applications requiring precision resistive elements with high power dissipation capability and wide operating temperature range. Equivalent and substitute parts are identified when design requirements change, inventory constraints occur, or performance specifications allow for upgraded alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the F10J150E is determined by matching the following critical parameters: resistance value (150 Ohms), tolerance (±5%), composition (wirewound), temperature coefficient (±260ppm/°C), operating temperature range (-55°C ~ 350°C), coating type (vitreous enamel), mounting feature (flange braces, right angle), lead style (solder lugs), and package configuration (radial, flat oval).

Two substitute relationships are identified:

Upgrade Substitute (F20J150E): Maintains all electrical and mechanical parameters identical to the main part except power rating increases from 10W to 20W. Physical dimensions change to accommodate higher power dissipation (length increases from 0.750" to 2.000").

Parametric Equivalent (F10J150): Maintains identical electrical specifications and physical dimensions as the main part. Differs only in RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

F20J150E (Upgrade Substitute): Select this part when circuit design allows for increased physical footprint and higher power dissipation capability is beneficial. Both the main part and this upgrade maintain ROHS3 compliance and active product status. The doubled power rating (20W vs 10W) provides design margin in applications where thermal management is a consideration. Physical dimensions increase in length only; width and height remain unchanged, allowing potential accommodation in existing layouts with sufficient axial space.

F10J150 (Parametric Equivalent): Select this part for direct form-fit-function replacement when RoHS compliance is not a design requirement. Electrical specifications, physical dimensions, and thermal characteristics are identical to the F10J150E. This part is RoHS non-compliant, making it unsuitable for applications or markets with mandatory RoHS requirements.

Frequently Asked Questions (FAQ)

Q: Can F20J150E be used as a direct replacement for F10J150E? A: F20J150E is functionally compatible as a substitute. All electrical parameters and mechanical mounting features are identical. The primary difference is increased power rating (20W vs 10W) and increased length (2.000" vs 0.750"). Verify available board space before substitution.

Q: What is the difference between F10J150E and F10J150? A: Both parts are electrically and mechanically identical. The primary difference is RoHS compliance status: F10J150E is ROHS3 compliant, while F10J150 is RoHS non-compliant. Select based on regulatory requirements for your application.

Q: Are all three parts from the same manufacturer? A: Yes, all three parts (F10J150E, F20J150E, and F10J150) are manufactured by Ohmite and belong to the Stackohm® 250 series.

Q: Do the substitute parts have the same operating temperature range? A: Yes, all three parts operate across the identical temperature range of -55°C to 350°C with the same temperature coefficient of ±260ppm/°C.

Q: What packaging considerations apply when substituting F20J150E? A: F20J150E has a significantly longer body (2.000" vs 0.750"). Verify that your PCB layout or chassis mounting location has sufficient axial clearance. Width and height dimensions remain unchanged at 0.375".
