Parameter Comparison

Engineering Selection Recommendations

TL2BR033F (Direct Equivalent)

The TL2BR033F is a direct electrical and mechanical equivalent to the TL2BR033FTE. Both components share identical resistance, tolerance, power rating, package, composition, and operating specifications. The primary distinction is packaging format: TL2BR033F is supplied in Cut Tape (CT) format versus Tape & Reel (TR) for the original part. This substitute is suitable for applications requiring exact specification matching and is available in higher inventory quantities (7103 pcs). However, this part maintains obsolete product status.

TLRP2B10WR033FTD (Manufacturer Recommended)

The TLRP2B10WR033FTD is the manufacturer-recommended upgrade path from TE Connectivity. This component maintains the 33 mOhm resistance, ±1% tolerance, and 1206 package while offering enhanced power rating (1W versus 0.25W), active product status, and automotive AEC-Q200 certification. The anti-sulfur feature provides additional environmental protection. The operating temperature range is slightly narrower (-55°C to 170°C versus -65°C to 170°C). This part is actively manufactured and represents the preferred long-term solution for new designs and production continuity.

KRL1632E-M-R033-F-T5 (Upgrade Alternative)

The KRL1632E-M-R033-F-T5 from Susumu provides an alternative upgrade path with intermediate power rating (0.75W) and improved temperature coefficient (±50ppm/°C versus ±75ppm/°C). This component carries automotive AEC-Q200 certification and maintains active product status. The operating temperature range is -55°C to 155°C. Extensive inventory availability (195823 pcs) supports high-volume production requirements. This part is suitable for applications where enhanced thermal performance and automotive-grade reliability are required.

Frequently Asked Questions (FAQ)

Q: Can TL2BR033F be used as a direct replacement for TL2BR033FTE?

A: Yes. TL2BR033F is electrically and mechanically equivalent to TL2BR033FTE. Both components have identical resistance (33 mOhms), tolerance (±1%), power rating (0.25W), package (1206), composition (Metal Foil), and operating temperature range (-65°C to 170°C). The only difference is packaging format (Cut Tape versus Tape & Reel). Both parts are obsolete.

Q: What is the advantage of TLRP2B10WR033FTD over the original TL2BR033FTE?

A: TLRP2B10WR033FTD offers four key advantages: (1) Active product status ensuring long-term availability, (2) Higher power rating (1W versus 0.25W) providing thermal margin, (3) Automotive AEC-Q200 certification for enhanced reliability, and (4) Anti-sulfur feature for environmental protection. Electrical specifications (resistance, tolerance, temperature coefficient) remain equivalent.

Q: Is KRL1632E-M-R033-F-T5 compatible with designs specified for TL2BR033FTE?

A: KRL1632E-M-R033-F-T5 is mechanically and electrically compatible with TL2BR033FTE in the 1206 package. The component maintains 33 mOhm resistance and ±1% tolerance. The higher power rating (0.75W) and improved temperature coefficient (±50ppm/°C) represent performance enhancements. The operating temperature range is narrower (-55°C to 155°C versus -65°C to 170°C), which must be verified against application requirements.

Q: What packaging formats are available for these substitute parts?

A: TL2BR033F is supplied in Cut Tape (CT) format. Both TLRP2B10WR033FTD and KRL1632E-M-R033-F-T5 are supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for high-volume production and automated assembly. Cut Tape format is suitable for lower-volume or manual assembly applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. TL2BR033F, TLRP2B10WR033FTD, and KRL1632E-M-R033-F-T5 are all ROHS3 compliant. All components have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Which substitute part should be selected for new automotive applications?

A: TLRP2B10WR033FTD or KRL1632E-M-R033-F-T5 are both suitable for automotive applications, as both carry AEC-Q200 certification. TLRP2B10WR033FTD is the manufacturer-recommended upgrade from TE Connectivity. KRL1632E-M-R033-F-T5 offers improved temperature coefficient performance. Selection depends on specific thermal and reliability requirements of the application.

Q: What is the temperature coefficient difference between substitute parts?

A: TL2BR033FTE, TL2BR033F, and TLRP2B10WR033FTD all have ±75ppm/°C temperature coefficient. KRL1632E-M-R033-F-T5 has ±50ppm/°C, representing a 33% improvement in temperature stability. Lower temperature coefficient values indicate better resistance stability across temperature variations.
