Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL3AR01F is determined by strict equivalence in the following core parameters:

Critical Parameters for Substitution:

• Resistance value: 10 mOhms
• Tolerance: ±1%
• Package / Case: 2512 (6432 Metric)
• Composition: Metal Foil
• Features: Current Sense capability
• Number of Terminations: 2

Allowable Variations:

• Power rating may be equal or higher (1W or greater)
• Temperature coefficient may vary within acceptable ranges for the application
• Operating temperature range may be extended
• Packaging format (Cut Tape vs. Tape & Reel) does not affect electrical equivalence
• Product status transition from obsolete to active is acceptable for substitution purposes

The identified substitute parts maintain all critical electrical and mechanical parameters while offering either enhanced power handling capability or automotive-grade qualification.

Parameter Comparison

Engineering Selection Recommendations

TLRP3A20WR010FTE (TE Connectivity Passive Product)

This part is the manufacturer-recommended substitute from TE Connectivity. It maintains identical resistance, tolerance, and package specifications while providing doubled power rating (2W vs. 1W). The part is in active production status, ensuring long-term availability. ROHS3 compliance is maintained. The increased height (0.035" vs. 0.024") and higher temperature coefficient (±100 ppm/°C vs. ±75 ppm/°C) must be evaluated against specific application requirements. This option is suitable for applications requiring enhanced thermal performance or where the original 1W rating approaches design limits.

KRL3264-C-R010-F-T1 (Susumu)

This part provides automotive-grade qualification (AEC-Q200) with equivalent 1W power rating and improved temperature coefficient (±50 ppm/°C). The part is in active production status. ROHS3 and REACH compliance are confirmed. Dimensional variations are minimal (6.30mm x 3.10mm vs. 6.40mm x 3.20mm), and height is comparable (0.028" vs. 0.024"). This option is appropriate for automotive applications or designs requiring superior temperature stability and extended operating range (-55°C ~ 175°C).

Both substitute parts are in active production, ensuring procurement continuity and eliminating obsolescence risk associated with the TL3AR01F.

Frequently Asked Questions (FAQ)

Q: Can TLRP3A20WR010FTE be used as a direct replacement for TL3AR01F?

A: Yes. Both parts share identical resistance (10 mOhms), tolerance (±1%), package (2512), and composition (metal foil). The TLRP3A20WR010FTE provides higher power rating (2W vs. 1W) and is in active production status. Physical height differs (0.035" vs. 0.024"), requiring PCB layout verification.

Q: What are the dimensional differences between substitute parts?

A: The KRL3264-C-R010-F-T1 has slightly smaller length and width (6.30mm x 3.10mm vs. 6.40mm x 3.20mm for TL3AR01F) and comparable height (0.028" vs. 0.024"). The TLRP3A20WR010FTE maintains identical length and width but has greater height (0.035"). All three parts fit the 2512 (6432 Metric) package classification.

Q: Which substitute is better for high-temperature applications?

A: The KRL3264-C-R010-F-T1 offers extended operating range (-55°C ~ 175°C vs. -65°C ~ 170°C) and superior temperature coefficient (±50 ppm/°C vs. ±75 ppm/°C), providing better stability across temperature variations.

Q: Are both substitutes RoHS compliant?

A: Yes. Both TLRP3A20WR010FTE and KRL3264-C-R010-F-T1 are ROHS3 compliant, matching the compliance status of the original TL3AR01F.

Q: What is the significance of AEC-Q200 qualification on the KRL3264-C-R010-F-T1?

A: AEC-Q200 is an automotive industry standard qualification. This certification indicates the part meets automotive reliability and quality requirements, making it suitable for automotive applications where such qualification is mandatory.

Q: Can packaging format (Cut Tape vs. Tape & Reel) affect substitution?

A: No. Packaging format affects procurement and handling but does not impact electrical or mechanical compatibility. Both Cut Tape (CT) and Tape & Reel (TR) formats contain electrically identical components.

Q: What is the impact of different temperature coefficients on circuit performance?

A: Temperature coefficient determines resistance change over temperature. The TL3AR01F has ±75 ppm/°C, TLRP3A20WR010FTE has ±100 ppm/°C, and KRL3264-C-R010-F-T1 has ±50 ppm/°C. Applications requiring high precision across temperature ranges benefit from lower coefficients.
