TPS2071DAPG4 Equivalent & Substitute Parts

Part Overview

The TPS2071DAPG4 is a Power Switch/Driver IC designed for PCMCIA power interface applications, manufactured by Texas Instruments in a 32-HTSSOP surface mount package. This component is classified as a Power Management (PMIC) device and operates across the industrial temperature range of -40°C to 85°C.

The TPS2071DAPG4 has been discontinued at DiGi Electronics, making it necessary to identify equivalent substitute parts for ongoing design support and procurement. The primary substitute maintains identical electrical and mechanical specifications while offering active product status and improved availability.

Substitute Part Grouping Explanation

Substitution of the TPS2071DAPG4 is determined by strict equivalence across the following critical parameters:

• Base Product Number: Both parts share the TPS2071 base designation, confirming identical die and electrical functionality
• Package Specification: Both utilize the 32-PowerTSSOP (0.240", 6.10mm Width) package, ensuring mechanical and thermal compatibility
• Supplier Device Package: Both are specified as 32-HTSSOP, confirming pinout and footprint compatibility
• Operating Temperature Range: Identical -40°C to 85°C specification ensures thermal performance equivalence
• Compliance Standards: Both maintain ROHS3 compliance, REACH Unaffected status, and identical MSL rating

The substitute part differs only in packaging format (Tube vs. unspecified for the original) and product status (Active vs. Discontinued), with no impact on electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The TPS2071DAP is the manufacturer-recommended substitute for the discontinued TPS2071DAPG4. Selection of this substitute is based on the following engineering criteria:

Electrical Equivalence: Both parts share the identical TPS2071 base product number, confirming equivalent die design and electrical performance across all operating conditions.

Mechanical Compatibility: The 32-PowerTSSOP package specification and 32-HTSSOP supplier device package are identical, ensuring direct footprint compatibility on existing PCB layouts without design modification.

Thermal Performance: Identical operating temperature range (-40°C to 85°C) and MSL rating (3, 168 Hours) confirm equivalent thermal and moisture handling characteristics.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying equivalent environmental and regulatory requirements.

Product Availability: The TPS2071DAP maintains active product status with 3156 units in stock, providing reliable procurement compared to the discontinued TPS2071DAPG4.

Frequently Asked Questions (FAQ)

Q: Can the TPS2071DAP be used as a direct replacement for the TPS2071DAPG4?

A: Yes. Both parts share identical electrical specifications, package dimensions, pinout configuration, and operating temperature range. No circuit design changes are required for substitution.

Q: Are there any differences in the 32-PowerTSSOP package between these parts?

A: No. Both parts utilize the identical 32-PowerTSSOP (0.240", 6.10mm Width) package with 32-HTSSOP pinout. PCB footprints and assembly processes remain unchanged.

Q: What is the difference between the TPS2071DAPG4 and TPS2071DAP packaging formats?

A: The TPS2071DAPG4 packaging format is not specified in the available data. The TPS2071DAP is supplied in Tube packaging. This difference does not affect electrical or mechanical compatibility; it relates only to order quantity and handling logistics.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the TPS2071DAPG4 and TPS2071DAP are ROHS3 compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Q: Why is the TPS2071DAPG4 discontinued?

A: Product discontinuation at DiGi Electronics does not indicate a design flaw or obsolescence of the underlying TPS2071 technology. The manufacturer-recommended substitute TPS2071DAP provides continued access to this proven power management solution.

Q: What is the MSL rating and why does it matter?

A: Both parts carry an MSL rating of 3 (168 Hours), indicating identical moisture sensitivity and storage requirements. Components must be stored in controlled humidity environments and baked before reflow soldering if moisture absorption limits are exceeded.
