Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL2BR047FTE is determined by the following critical parameters: resistance value (47 mOhms), tolerance (±1%), package type (1206), composition (metal foil), and current sense application. All substitute parts maintain these core electrical and mechanical specifications.

Substitutes are grouped into three categories based on product status and power rating enhancements:

Direct Equivalent: TL2BR047F maintains identical electrical specifications and packaging but differs in product status (obsolete) and packaging format (Cut Tape versus Tape & Reel).

Manufacturer Recommended Upgrade: TLM2BDR047FTD provides increased power rating (0.5W versus 0.25W) while maintaining the same resistance, tolerance, and package. This part is active and available in Tape & Reel format.

Enhanced Upgrade: KRL1632E-M-R047-F-T5 from Susumu offers the highest power rating (0.75W) with automotive AEC-Q200 qualification, maintaining all core electrical parameters and package specifications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: TL2BR047F serves as a direct electrical equivalent to TL2BR047FTE. Both parts are classified as obsolete; however, TL2BR047F maintains higher inventory availability (21,555 pieces) compared to TL2BR047FTE (937 pieces). Selection of TL2BR047F is appropriate when packaging format (Cut Tape) is compatible with assembly processes and when the 0.25W power rating meets thermal requirements.

For Active Component Sourcing: TLM2BDR047FTD is the manufacturer-recommended upgrade from TE Connectivity. This part is active and available in Tape & Reel format, providing improved long-term supply chain stability. The increased power rating (0.5W) provides thermal margin over the original 0.25W specification. The temperature coefficient improves to ±50ppm/°C, and operating temperature range adjusts to -55°C ~ 155°C. Selection is appropriate when the reduced upper operating temperature limit (-55°C minimum versus -65°C) and narrower temperature range are acceptable for the application.

For Automotive and Enhanced Reliability Applications: KRL1632E-M-R047-F-T5 from Susumi offers the highest power rating (0.75W) with automotive AEC-Q200 qualification. This part is active with substantial inventory (54,848 pieces). The ±50ppm/°C temperature coefficient and -55°C ~ 155°C operating range match TLM2BDR047FTD. Selection is appropriate for automotive applications, designs requiring enhanced thermal headroom, or when AEC-Q200 compliance is specified.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and metal foil composition required for current sense applications.

Frequently Asked Questions (FAQ)

Q: Can TL2BR047F be used as a direct replacement for TL2BR047FTE?

A: Yes. TL2BR047F is electrically and mechanically identical to TL2BR047FTE, maintaining the same 47 mOhm resistance, ±1% tolerance, 0.25W power rating, 1206 package, and metal foil composition. The primary difference is packaging format (Cut Tape versus Tape & Reel) and product status (both obsolete). Compatibility depends on assembly equipment compatibility with Cut Tape format.

Q: What are the implications of upgrading to TLM2BDR047FTD?

A: TLM2BDR047FTD doubles the power rating from 0.25W to 0.5W while maintaining all core electrical parameters (47 mOhms, ±1% tolerance, metal foil, current sense). The temperature coefficient improves from ±75ppm/°C to ±50ppm/°C. The operating temperature range narrows from -65°C ~ 170°C to -55°C ~ 155°C. This upgrade is suitable when the reduced upper temperature limit is acceptable and thermal margin is beneficial. TLM2BDR047FTD is active and available in Tape & Reel format.

Q: When should KRL1632E-M-R047-F-T5 be selected over other substitutes?

A: KRL1632E-M-R047-F-T5 should be selected when automotive AEC-Q200 qualification is required, when maximum thermal headroom is needed (0.75W power rating), or when the highest inventory availability is prioritized (54,848 pieces). This part is active and maintains all core electrical specifications. The operating temperature range (-55°C ~ 155°C) and temperature coefficient (±50ppm/°C) are identical to TLM2BDR047FTD.

Q: Are all substitute parts compatible with the 1206 package footprint?

A: Yes. All substitute parts use the 1206 (3216 Metric) package. Physical dimensions vary slightly: TL2BR047FTE and TL2BR047F measure 0.126" L × 0.063" W (3.20mm × 1.60mm) with 0.024" maximum seated height, while TLM2BDR047FTD measures 0.120" L × 0.061" W (3.05mm × 1.55mm) with 0.028" maximum seated height, and KRL1632E-M-R047-F-T5 measures 0.126" L × 0.063" W (3.20mm × 1.60mm) with 0.028" maximum seated height. These variations are within standard 1206 package tolerances and compatible with standard 1206 footprints.

Q: Do all substitute parts maintain RoHS3 compliance?

A: Yes. TL2BR047F, TLM2BDR047FTD, and KRL1632E-M-R047-F-T5 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of TL2BR047FTE.

Q: What is the significance of the temperature coefficient difference between substitutes?

A: TL2BR047FTE and TL2BR047F specify ±75ppm/°C, while TLM2BDR047FTD and KRL1632E-M-R047-F-T5 specify ±50ppm/°C. The lower temperature coefficient in the upgraded parts indicates improved resistance stability across temperature variations. For current sense applications where precision is critical, the ±50ppm/°C specification provides tighter tolerance maintenance over the operating temperature range.
