F20J200 Equivalent & Substitute Parts

Part Overview

The F20J200 is a 200 Ohms ±5% 20W wirewound chassis mount resistor manufactured by Ohmite, part of the Stackohm® 250 series. This component is designed for applications requiring high power dissipation with stable resistance values across extended temperature ranges. The part is currently active in production with 942 units in stock. Equivalent and substitute parts are identified when design requirements permit operation at reduced power ratings or when alternative compliance certifications are necessary for specific applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the F20J200 is permissible when the following conditions are met:

Critical Parameters (Must Match):

• Resistance value: 200 Ohms
• Tolerance: ±5%
• Composition: Wirewound
• Temperature Coefficient: ±260ppm/°C
• Operating Temperature Range: -55°C to 350°C
• Coating/Housing Type: Vitreous Enamel Coated
• Mounting Feature: Flange Braces, Right Angle
• Lead Style: Solder Lugs
• Package/Case: Radial, Flat Oval
• Physical Dimensions: 0.750" L x 0.375" W (19.05mm x 9.53mm)

Variable Parameters (May Differ):

• Power Rating: May be reduced if circuit design permits lower power dissipation
• RoHS Compliance Status: May differ based on application requirements
• Packaging Format: May vary (Bulk vs. other formats)

The F10J200E qualifies as a parametric equivalent because it maintains all critical electrical and mechanical specifications while operating at a reduced 10W power rating.

Parameter Comparison

Engineering Selection Recommendations

F20J200 Selection Criteria:

• Applications requiring 20W continuous power dissipation
• Designs where RoHS non-compliance is acceptable or not required
• Circuits operating within the full -55°C to 350°C temperature range with maximum thermal load

F10J200E Selection Criteria:

• Applications with power dissipation requirements of 10W or less
• Designs requiring ROHS3 compliance certification
• Systems where reduced power rating meets thermal and electrical specifications
• Moisture-sensitive environments where MSL 1 rating is required

Both parts maintain identical electrical performance characteristics (resistance, tolerance, temperature coefficient) and mechanical compatibility (mounting, dimensions, lead configuration). Selection between these parts depends on power rating requirements and compliance certifications mandated by the application or regulatory framework.

Frequently Asked Questions (FAQ)

Q: Can F10J200E replace F20J200 in all applications? A: F10J200E can replace F20J200 only when circuit power dissipation does not exceed 10W. The 10W rating is the limiting factor. If the circuit requires more than 10W dissipation, F10J200E is not suitable.

Q: What is the primary difference between these parts? A: The primary difference is power rating: F20J200 is rated for 20W, while F10J200E is rated for 10W. All other electrical and mechanical parameters are identical.

Q: Does RoHS compliance affect electrical performance? A: No. RoHS compliance status does not affect electrical performance, resistance value, tolerance, or temperature characteristics. It is a manufacturing and material certification requirement only.

Q: Are the physical dimensions identical? A: Yes. Both parts have identical dimensions of 0.750" L x 0.375" W (19.05mm x 9.53mm) and maximum seated height of 0.375" (9.53mm). They are mechanically interchangeable in terms of mounting and board layout.

Q: What does Moisture Sensitivity Level (MSL) 1 mean? A: MSL 1 indicates unlimited floor life. The component can be stored and handled without time restrictions or special moisture control measures. The F20J200 lists MSL as Not Applicable, indicating this parameter does not apply to that part variant.

Q: Can these parts be used interchangeably in high-temperature applications? A: Yes, both parts operate across the identical temperature range of -55°C to 350°C with the same temperature coefficient of ±260ppm/°C. Temperature performance is equivalent.

Q: What is the significance of the Stackohm® 250 series designation? A: Stackohm® 250 is the product series name from Ohmite. Both parts belong to this same series, indicating they share common design characteristics and manufacturing standards.
