Substitute Part Grouping Explanation

Substitution eligibility for the TPS65820RSHT is determined by the following parameters:

Battery Chemistry: Lithium Ion/Polymer (single-cell)
Function: Multi-Function Controller with integrated charging and protection
Fault Protection: Over Current and Over Voltage protection capability
Interface: I2C and USB communication support
Operating Temperature Range: -40°C ~ 85°C (TA)
Mounting Type: Surface Mount
Package Category: 56-pin QFN with Exposed Pad
Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

The substitute parts TPS65810RTQT, TPS65811RTQR, and TPS65811RTQT meet all functional and electrical requirements. Variations in package dimensions (7x7 mm versus 8x8 mm), product status, and moisture sensitivity level represent the primary differences requiring design review.

Engineering Selection Recommendations

TPS65810RTQT is suitable for applications where Last Time Buy status is acceptable and package footprint can accommodate the 8x8 mm QFN variant. This part maintains full functional equivalence with improved moisture sensitivity handling (MSL 3) compared to the original TPS65820RSHT.

TPS65811RTQR offers identical functional specifications to TPS65810RTQT with Tape & Reel packaging, appropriate for high-volume production environments. Last Time Buy status applies.

TPS65811RTQT provides functional equivalence with Discontinued at DiGi Electronics status. This part is suitable only for applications where alternative supply channels are established or existing inventory is available.

All substitute parts maintain ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements. PCB layout modifications are required to accommodate the package dimension change from 56-VQFN (7x7) to 56-QFN (8x8).

Frequently Asked Questions (FAQ)

Q: Can TPS65810RTQT or TPS65811RTQR be used as direct replacements for TPS65820RSHT?

A: Functional equivalence is confirmed across all critical parameters: battery chemistry, cell count, protection features, and communication interfaces. However, the package footprint differs (7x7 mm versus 8x8 mm), requiring PCB layout redesign.

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

A: The TPS65820RSHT carries MSL 1 (Unlimited shelf life), while substitute parts carry MSL 3 (168-hour maximum floor life after moisture exposure). Storage and handling procedures must comply with MSL 3 requirements for substitute parts.

Q: Are there packaging format differences between the substitute parts?

A: TPS65810RTQT is supplied in Tape & Reel format. TPS65811RTQR is also supplied in Tape & Reel format. TPS65811RTQT packaging format is not specified. Verify packaging requirements with your procurement process.

Q: Do all parts support the same operating temperature range?

A: Yes. All parts operate across -40°C to 85°C (TA), maintaining thermal performance equivalence.

Q: What is the impact of product status on part selection?

A: TPS65820RSHT is Obsolete. TPS65810RTQT and TPS65811RTQR are Last Time Buy. TPS65811RTQT is Discontinued at DiGi Electronics. Procurement strategy should prioritize Last Time Buy parts for new designs, with inventory planning accordingly.
