TL3AR006FTDG Equivalent & Substitute Parts

Part Overview

The TL3AR006FTDG is a 6 milliohm, ±1% tolerance, 1W chip resistor in 2512 (6432 Metric) package manufactured by TE Connectivity Passive Product. This metal foil current sense resistor is designed for precision low-resistance applications requiring high accuracy and stable performance across temperature ranges from -65°C to 170°C. The part is classified as obsolete, necessitating identification of active equivalent components that maintain electrical and mechanical compatibility for ongoing production and replacement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL3AR006FTDG is determined by strict equivalence in the following critical parameters:

Mandatory Equivalence Parameters:

• Resistance value: 6 mOhms
• Tolerance: ±1%
• Package / Case: 2512 (6432 Metric)
• Temperature Coefficient: ±75ppm/°C
• Number of Terminations: 2
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations:

• Power rating may be equal or greater than the original 1W specification
• Composition may differ (Metal Element acceptable as equivalent to Metal Foil for current sense applications)
• Operating temperature minimum may be higher (-55°C acceptable versus -65°C)
• Operating temperature maximum remains at or above 170°C
• Product status may transition from obsolete to active
• Additional certifications (AEC-Q200, Anti-Sulfur) are permissible enhancements

The TLRP3A20WR006FTE meets all mandatory equivalence parameters while offering enhanced power rating (2W) and automotive qualification, making it a direct substitute for the obsolete TL3AR006FTDG.

Parameter Comparison

Engineering Selection Recommendations

The TLRP3A20WR006FTE is the direct substitute for the obsolete TL3AR006FTDG based on the following engineering criteria:

Electrical Equivalence: Both components maintain identical resistance (6 mOhms), tolerance (±1%), and temperature coefficient (±75ppm/°C), ensuring equivalent performance in current sense applications.

Mechanical Compatibility: Both parts utilize the 2512 (6432 Metric) package with identical footprint dimensions (0.252" L x 0.126" W). The substitute exhibits a maximum seated height of 0.035" (0.90mm) compared to 0.024" (0.60mm) for the original part. This height differential must be evaluated against specific PCB assembly constraints.

Compliance Status: The TLRP3A20WR006FTE is an active product with ROHS3 compliance and AEC-Q200 automotive qualification, providing enhanced supply chain availability and extended product lifecycle support compared to the obsolete TL3AR006FTDG.

Power Rating Enhancement: The substitute provides 2W power rating versus the original 1W specification, offering improved thermal margin and reliability in current sense applications without compromising electrical characteristics.

Temperature Operating Range: The substitute operates from -55°C to 170°C, compared to the original -65°C to 170°C. Applications requiring operation below -55°C require alternative component evaluation.

Frequently Asked Questions (FAQ)

Q: Can the TLRP3A20WR006FTE directly replace the TL3AR006FTDG in existing designs?

A: The TLRP3A20WR006FTE provides electrical and mechanical substitution for the TL3AR006FTDG with the following considerations: identical resistance, tolerance, and temperature coefficient ensure functional equivalence; identical package footprint (2512) and termination count (2) support PCB compatibility; the substitute's maximum seated height of 0.035" (0.90mm) versus 0.024" (0.60mm) must be verified against assembly clearance requirements; the lower operating temperature minimum (-55°C versus -65°C) must be confirmed acceptable for the application.

Q: What are the key differences between these two components?

A: The primary differences are: power rating (2W substitute versus 1W original), providing enhanced thermal performance; product status (active substitute versus obsolete original), ensuring long-term availability; composition (Metal Element versus Metal Foil), both acceptable for current sense applications; additional certifications (AEC-Q200 automotive qualification on substitute); operating temperature minimum (-55°C substitute versus -65°C original); packaging format (Tape & Reel substitute versus bulk original).

Q: Are there any height clearance concerns with the substitute part?

A: The TLRP3A20WR006FTE has a maximum seated height of 0.035" (0.90mm) compared to 0.024" (0.60mm) for the TL3AR006FTDG. This 0.011" (0.30mm) height increase must be evaluated against PCB assembly specifications, component stacking requirements, and enclosure clearances to confirm compatibility.

Q: Does the substitute part maintain the same electrical performance?

A: Yes. Both components specify 6 mOhms resistance with ±1% tolerance and ±75ppm/°C temperature coefficient. Electrical performance in current sense applications remains equivalent. The 2W power rating of the substitute provides additional thermal margin compared to the 1W original specification.

Q: Is the substitute part suitable for automotive applications?

A: The TLRP3A20WR006FTE carries AEC-Q200 automotive qualification and Anti-Sulfur features, making it suitable for automotive environments. The original TL3AR006FTDG does not specify automotive qualification. Applications requiring automotive-grade components benefit from the substitute's enhanced certifications.

Q: What is the minimum operating temperature difference between these parts?

A: The substitute operates from -55°C minimum, while the original operates from -65°C minimum. This 10°C difference must be confirmed acceptable for applications requiring operation at temperatures below -55°C.
