Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TL2BR047F is determined by strict equivalence in the following critical parameters:

Mandatory Equivalence Parameters:

• Resistance value: 47 mOhms
• Tolerance: ±1%
• Package type: 1206 (3216 Metric)
• Composition: Metal Foil
• Feature set: Current Sense application

Allowable Variation Parameters:

• Power rating: May increase from 0.25W to higher ratings (0.5W, 0.75W) without functional degradation
• Temperature coefficient: May decrease (improve) from ±75 ppm/°C to ±50 ppm/°C
• Operating temperature range: May shift within industrial/automotive specifications
• Product status: Active parts are preferred over obsolete classifications
• Packaging format: Cut Tape (CT) may be substituted with Tape & Reel (TR) for procurement flexibility

The substitute parts listed maintain identical electrical specifications for resistance, tolerance, and package footprint while offering enhanced performance characteristics or improved availability status.

Parameter Comparison

Engineering Selection Recommendations

TLM2BDR047FTD (TE Connectivity Passive Product): This part serves as the direct manufacturer-recommended substitute. It maintains identical electrical specifications while offering active product status and improved availability. The increased power rating (0.5W versus 0.25W) provides design margin without altering circuit behavior. The improved temperature coefficient (±50 ppm/°C versus ±75 ppm/°C) enhances measurement accuracy in current sensing applications. This substitute is appropriate for direct replacement in existing designs without circuit modification.

KRL1632E-M-R047-F-T5 (Susumu): This part represents an upgrade option with the highest power rating (0.75W) and automotive-grade qualification (AEC-Q200). The identical resistance, tolerance, and package specifications ensure mechanical and electrical compatibility. The AEC-Q200 certification indicates compliance with automotive reliability standards. This upgrade is suitable for applications requiring enhanced thermal performance or automotive-grade component qualification. Both substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can TLM2BDR047FTD be used as a direct replacement for TL2BR047F?

A: Yes. Both parts share identical resistance (47 mOhms), tolerance (±1%), package (1206), composition (metal foil), and current sense features. The increased power rating (0.5W versus 0.25W) does not affect circuit operation and provides additional thermal margin. The improved temperature coefficient enhances performance.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape packaging supplies individual components on tape segments suitable for manual handling and small-quantity applications. Tape & Reel packaging provides components on continuous reels for automated assembly equipment. Both formats contain identical components; packaging selection depends on assembly process requirements.

Q: Is KRL1632E-M-R047-F-T5 compatible with the original TL2BR047F footprint?

A: Yes. All three parts use the 1206 (3216 Metric) package with identical footprint dimensions. The KRL1632E-M-R047-F-T5 maintains the same land pattern and solder pad configuration, enabling direct PCB placement without layout modification.

Q: Why does the operating temperature range differ between parts?

A: The TL2BR047F specifies -65°C to 170°C, while substitutes specify -55°C to 155°C. Both ranges cover standard industrial and automotive operating conditions. Selection depends on specific application temperature requirements. The narrower range of substitute parts does not indicate reduced capability within their specified limits.

Q: What does AEC-Q200 certification mean for the KRL1632E-M-R047-F-T5?

A: AEC-Q200 is an automotive industry standard for passive component reliability. This certification indicates the part meets automotive-grade qualification requirements for temperature cycling, moisture resistance, and failure rate specifications. This qualification is relevant for automotive and high-reliability applications.

Q: Are all three parts RoHS3 compliant?

A: Yes. TL2BR047F, TLM2BDR047FTD, and KRL1632E-M-R047-F-T5 are all ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for electronic component manufacturing and use.

Q: Can the higher power rating of substitute parts affect circuit performance?

A: No. Higher power ratings indicate increased thermal capacity without changing electrical characteristics. The resistance, tolerance, and temperature coefficient remain constant. Higher power ratings provide design margin and improved thermal stability without adverse effects on circuit operation.
