Key Parameters

Substitute Part Grouping Explanation

The D2TO035C10R00FTE3 qualifies as a direct substitute based on the following allowed parameters:

• Identical resistance value: 10 Ohms
• Identical tolerance: ±1%
• Identical package: TO-263-3, D2PAK (2 Leads + Tab)
• Identical composition: Thick Film
• Identical temperature coefficient: ±150ppm/°C
• Identical automotive qualification: AEC-Q200
• Identical features: Moisture Resistant, Non-Inductive
• Identical RoHS compliance: ROHS3 Compliant

The substitute part provides increased power dissipation capability (35W versus 20W) and an extended upper operating temperature limit (-55°C ~ 175°C versus -55°C ~ 155°C), making it suitable for higher thermal stress applications while maintaining all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both D2TO020C10R00FRE3 and D2TO035C10R00FTE3 are active production parts with identical AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts depends on thermal design requirements:

Use D2TO020C10R00FRE3 when the application thermal environment does not exceed 155°C and power dissipation remains within 20W limits.

Use D2TO035C10R00FTE3 when the application requires higher power dissipation capability or operates in thermal environments approaching or exceeding 155°C up to 175°C. The increased power rating and extended temperature range provide design margin without compromising electrical performance or compliance status.

Both parts maintain identical mechanical footprint, electrical characteristics, and regulatory compliance, enabling direct substitution in PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can D2TO035C10R00FTE3 replace D2TO020C10R00FRE3 in existing designs?

A: Yes. The substitute part maintains identical resistance, tolerance, package dimensions, and all electrical specifications. The increased power rating and extended temperature range represent design improvements without introducing incompatibility.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use TO-263-3 (D2PAK) package with identical dimensions: 0.398" L x 0.346" W (10.10mm x 8.80mm) and maximum seated height of 0.189" (4.80mm). PCB footprints are interchangeable.

Q: What is the difference in packaging between these parts?

A: D2TO020C10R00FRE3 is supplied in Tape & Reel (TR) packaging, while D2TO035C10R00FTE3 is supplied in Tube packaging. This affects handling and automated assembly processes but does not impact component performance or compatibility.
