UCC29002P Equivalent & Substitute Parts

Part Overview

The UCC29002P is a Load Share Controller PMIC manufactured by Texas Instruments in 8-DIP through-hole packaging. This component is classified as Last Time Buy, indicating discontinued production with limited remaining inventory. The UCC29002P operates across a supply voltage range of 4.375V to 14.25V with a supply current of 2.5mA and supports operating temperatures from -40°C to 105°C. Due to its Last Time Buy status, identifying functionally equivalent substitute parts is essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the UCC29002P is determined by electrical parameter equivalence and regulatory compliance alignment. The primary substitute, UCC29002DR, shares the identical base product number (UCC29002) and maintains all critical electrical specifications: supply voltage range (4.375V ~ 14.25V), supply current (2.5mA), and operating temperature range (-40°C ~ 105°C). Both parts are ROHS3 Compliant and REACH Unaffected, ensuring regulatory compatibility. The key differentiator is packaging format: the UCC29002P uses through-hole 8-DIP mounting, while the UCC29002DR uses surface-mount 8-SOIC packaging. This substitution is valid when circuit board design accommodates surface-mount technology and when the functional requirements of the Load Share Controller application remain unchanged.

Parameter Comparison

Engineering Selection Recommendations

The UCC29002DR is the manufacturer-recommended substitute for the UCC29002P. Both parts maintain identical electrical specifications and regulatory compliance certifications (ROHS3, REACH Unaffected, EAR99). The UCC29002DR carries Active product status, ensuring continued availability and long-term supply security compared to the Last Time Buy status of the UCC29002P. Selection between these parts depends on circuit board design constraints: the UCC29002P requires through-hole mounting capability, while the UCC29002DR requires surface-mount assembly infrastructure. Both parts are suitable for Load Share Controller applications within the specified electrical and thermal operating ranges.

Frequently Asked Questions (FAQ)

Q: Can the UCC29002DR directly replace the UCC29002P in existing designs? A: Electrical substitution is valid. The UCC29002DR maintains identical supply voltage (4.375V ~ 14.25V), supply current (2.5mA), and operating temperature range (-40°C ~ 105°C). However, circuit board layout must accommodate the different package format: 8-SOIC surface-mount versus 8-DIP through-hole. Pin-to-pin functional equivalence exists, but physical board modifications are required.

Q: Why is the UCC29002P listed as Last Time Buy? A: Last Time Buy status indicates Texas Instruments has discontinued production of the UCC29002P. The UCC29002DR, with identical electrical specifications and Active product status, is the recommended path for new designs and ongoing production.

Q: Are there compliance differences between the UCC29002P and UCC29002DR? A: No. Both parts are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99. Regulatory compliance is equivalent across both variants.

Q: What is the primary difference between these two parts? A: The primary difference is packaging and mounting technology. The UCC29002P uses 8-DIP through-hole packaging (0.300" width), while the UCC29002DR uses 8-SOIC surface-mount packaging (0.154" width). All electrical and functional specifications are identical.

Q: Is the UCC29002DR suitable for Load Share Controller applications? A: Yes. The UCC29002DR is specified for Load Share Controller applications with identical electrical parameters to the UCC29002P. Application suitability is determined by the Load Share Controller functional requirements, which remain unchanged between the two package variants.
