Substitute Part Grouping Explanation

Substitution of the TLM2BDR068FTD is permissible with parts that maintain the following critical parameters:

• Resistance Value: 68 mOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package / Case: 1206 (3216 Metric) (exact match required)
• Composition: Metal Foil (exact match required)
• Temperature Coefficient: ±50ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 155°C (exact match required)
• Features: Current Sense capability (exact match required)

The substitute part KRL1632E-M-R068-F-T5 satisfies all critical parameters. The power rating difference (0.75W versus 0.5W) represents an upgrade in thermal capability and does not restrict substitution in applications designed for the original 0.5W specification. Both parts are metal foil current sense resistors with identical electrical characteristics and package dimensions within specified tolerances.

Parameter Comparison

Engineering Selection Recommendations

Both the TLM2BDR068FTD and KRL1632E-M-R068-F-T5 are active products with full RoHS3 compliance and unlimited moisture sensitivity rating. The KRL1632E-M-R068-F-T5 carries AEC-Q200 automotive qualification, which provides additional reliability assurance for applications requiring automotive-grade components. The higher power rating (0.75W versus 0.5W) of the substitute part provides enhanced thermal margin without altering electrical performance in the 0.5W application envelope. Both parts are suitable for current sensing applications across the specified operating temperature range of -55°C to 155°C. Selection between these parts depends on supply availability, inventory requirements, and whether automotive qualification is mandated by application specifications.

Frequently Asked Questions (FAQ)

Q: Can the KRL1632E-M-R068-F-T5 be used as a direct replacement for the TLM2BDR068FTD?

A: Yes. Both parts share identical resistance (68 mOhms), tolerance (±1%), package (1206), composition (metal foil), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C to 155°C). The higher power rating of the substitute part (0.75W versus 0.5W) does not restrict its use in applications designed for 0.5W operation.

Q: What are the physical dimension differences between these parts?

A: The TLM2BDR068FTD measures 0.120" L x 0.061" W (3.05mm x 1.55mm), while the KRL1632E-M-R068-F-T5 measures 0.126" L x 0.063" W (3.20mm x 1.60mm). Both have identical maximum seated height of 0.028" (0.70mm). These minor dimensional variations remain within standard 1206 package tolerances and do not affect PCB layout compatibility.

Q: Does the AEC-Q200 qualification of the substitute part affect compatibility?

A: No. AEC-Q200 qualification represents an additional quality and reliability standard that does not restrict the part's use in non-automotive applications. It indicates enhanced testing and traceability suitable for automotive environments.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the TLM2BDR068FTD and KRL1632E-M-R068-F-T5 are RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Q: What is the significance of the metal foil composition for current sensing applications?

A: Metal foil construction provides superior temperature stability and low temperature coefficient (±50ppm/°C), which is critical for accurate current sensing where resistance drift directly affects measurement accuracy. Both parts employ metal foil technology, ensuring equivalent performance in current sensing circuits.
