Engineering Selection Recommendations

For Existing Designs Using TLRH2ATTD10L0F:

The TLR2ATTD10L0F serves as a direct functional substitute. Both parts share identical resistance, tolerance, package footprint, and automotive qualification. The substitute part offers increased power dissipation capability (1W versus 0.5W), which provides enhanced thermal margin in current sensing applications without requiring circuit redesign.

For New Design Implementations:

The TLR2ATTD10L0F is the recommended selection due to its Active product status. This part maintains full compatibility with existing PCB layouts and assembly processes while ensuring long-term supply availability and manufacturer support.

Compliance Considerations:

Both parts maintain ROHS3 compliance and AEC-Q200 automotive qualification. No regulatory or certification barriers exist for substitution. The MSL 1 rating for both parts indicates unlimited shelf life under standard storage conditions.

Physical Integration:

The maximum seated height difference is 0.004" (0.10mm), which remains within typical PCB assembly tolerances and does not affect component placement or clearance requirements in standard 0805 package applications.

Frequently Asked Questions (FAQ)

Q: Can TLR2ATTD10L0F replace TLRH2ATTD10L0F in existing production?

A: Yes. The substitute part maintains identical electrical specifications (10 mOhms, ±1% tolerance), package dimensions (0805), and automotive qualification (AEC-Q200). No circuit modifications are required.

Q: What is the significance of the power rating difference (0.5W vs. 1W)?

A: The substitute part has higher power dissipation capability. In current sensing applications, this provides additional thermal headroom. The higher rating does not negatively impact performance in circuits designed for 0.5W operation.

Q: Are there any height clearance concerns with the substitute part?

A: The seated height difference is 0.004" (0.10mm). This variation is within standard PCB assembly tolerances and does not create clearance issues in typical automotive applications.

Q: Why is TLRH2ATTD10L0F marked as Not For New Designs?

A: This designation indicates the part has been superseded by newer alternatives in the manufacturer's product line. TLR2ATTD10L0F represents the active equivalent for new design implementations.

Q: Do both parts meet the same automotive standards?

A: Yes. Both parts carry AEC-Q200 qualification and ROHS3 compliance. No differences exist in regulatory or automotive certification status.

Q: Is the temperature coefficient difference significant?

A: The temperature coefficient differs by ±25ppm/°C (±75ppm/°C versus ±100ppm/°C). Both values remain within automotive specification ranges for current sensing resistors. Selection depends on circuit-level accuracy requirements.

Q: What is the inventory status for each part?

A: TLRH2ATTD10L0F has 1,023 pieces in stock. TLR2ATTD10L0F has 45,832 pieces in stock, indicating superior long-term availability for ongoing production needs.
