Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLM2BDR027FTD is determined by strict equivalence in the following core parameters:

Critical Equivalence Parameters:

• Resistance value: 27 mOhms
• Tolerance: ±1%
• Package / Case: 1206 (3216 Metric)
• Composition: Metal Foil
• Temperature Coefficient: ±50 ppm/°C
• Operating Temperature Range: -55°C to +155°C
• Features: Current Sense application

Allowable Variation Parameters:

• Power Rating: Substitute parts may have equal or higher power ratings (0.5W or greater)
• RoHS Compliance: Substitute parts may have enhanced compliance status
• Automotive Certification: Substitute parts may include additional certifications such as AEC-Q200

The substitute part KRL1632E-M-R027-F-T5 meets all critical equivalence parameters and provides an upgraded power rating (0.75W versus 0.5W) with automotive-grade certification (AEC-Q200) and improved RoHS3 compliance status.

Parameter Comparison

Engineering Selection Recommendations

TLM2BDR027FTD Selection Criteria: The TLM2BDR027FTD is appropriate for applications where RoHS non-compliance is acceptable and standard 0.5W power dissipation is sufficient. This part maintains Active product status and is available in high inventory quantities (975 pcs).

KRL1632E-M-R027-F-T5 Selection Criteria: The KRL1632E-M-R027-F-T5 is the preferred substitute for applications requiring:

• ROHS3 compliance and REACH unaffected status
• Automotive-grade reliability (AEC-Q200 certification)
• Enhanced power handling capability (0.75W versus 0.5W)
• Higher inventory availability (15,237 pcs)

Both parts are electrically and mechanically equivalent in all critical parameters. The substitute part provides superior compliance certifications and automotive qualification, making it suitable for regulated environments and automotive applications. Dimensional variations are minimal and within standard PCB layout tolerances for 1206 package footprints.

Frequently Asked Questions (FAQ)

Q: Can KRL1632E-M-R027-F-T5 be used as a direct replacement for TLM2BDR027FTD?

A: Yes. Both parts share identical resistance (27 mOhms), tolerance (±1%), temperature coefficient (±50 ppm/°C), operating temperature range (-55°C to +155°C), composition (metal foil), and package (1206). The substitute has a higher power rating (0.75W versus 0.5W), which is a non-limiting upgrade. Dimensional differences are negligible for standard PCB layouts.

Q: What is the significance of the power rating difference?

A: The KRL1632E-M-R027-F-T5 has a 0.75W rating compared to the TLM2BDR027FTD's 0.5W rating. This allows the substitute to dissipate higher power levels without thermal stress. For applications operating within the original 0.5W specification, both parts perform identically. For applications approaching or exceeding 0.5W dissipation, the substitute provides additional thermal margin.

Q: Are there package compatibility concerns?

A: Both parts use the 1206 (3216 Metric) package. Dimensional variations (0.120" vs. 0.126" length; 0.061" vs. 0.063" width) are within standard PCB design tolerances and do not require layout modifications. Both parts have identical termination count (2) and moisture sensitivity rating (MSL 1).

Q: What compliance advantages does the substitute provide?

A: The KRL1632E-M-R027-F-T5 is ROHS3 compliant and REACH unaffected, whereas the TLM2BDR027FTD is RoHS non-compliant with undefined REACH status. The substitute also carries AEC-Q200 automotive qualification, making it suitable for regulated and automotive applications.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both the TLM2BDR027FTD and KRL1632E-M-R027-F-T5 are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: What is the temperature coefficient significance?

A: Both parts have an identical temperature coefficient of ±50 ppm/°C, ensuring equivalent resistance stability across the operating temperature range of -55°C to +155°C. This parameter is critical for current sensing applications where accuracy is required across temperature variations.
