UC2907NG4 Equivalent & Substitute Parts

Part Overview

The UC2907NG4 is a Load Share Controller PMIC manufactured by Texas Instruments in a 16-DIP through-hole package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new designs. The UC2907NG4 operates across a supply voltage range of 4.5V to 35V with a supply current of 6mA and supports operating temperatures from -40°C to 85°C. Identifying compatible substitutes ensures design continuity and component availability for load sharing applications.

Substitute Part Grouping Explanation

Substitution for the UC2907NG4 is determined by functional equivalence as a Load Share Controller and compatibility across the following critical parameters: supply voltage range, operating temperature range, package type, and mounting technology. The UC2907N maintains identical electrical specifications and through-hole DIP packaging, making it a direct functional equivalent. The UCC29002DR represents an advanced alternative with different packaging (8-SOIC surface mount) and modified electrical specifications, suitable only when PCB layout and voltage/current requirements permit the substitution.

Substitution logic is based on:

• Functional classification: Load Share Controller
• Supply voltage compatibility
• Operating temperature range
• Package and mounting type compatibility
• RoHS and regulatory compliance

Parameter Comparison

Engineering Selection Recommendations

UC2907N is the primary substitute for UC2907NG4. Both components share identical electrical specifications, package geometry, and mounting technology. The UC2907N is ROHS3 compliant and currently in Last Time Buy status, providing a direct replacement path for through-hole applications requiring the full 4.5V to 35V supply voltage range.

UCC29002DR is an alternative substitute suitable only when system design permits surface-mount technology and operates within the reduced voltage range of 4.375V to 14.25V. This component is in Active product status and offers extended operating temperature capability to 105°C. The UCC29002DR requires PCB redesign for surface-mount implementation and is not pin-compatible with the original DIP package.

All substitute options maintain ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can UC2907N directly replace UC2907NG4 without PCB modifications? A: Yes. UC2907N is a direct functional equivalent with identical package dimensions (16-DIP), mounting type (through hole), and electrical specifications (4.5V ~ 35V supply, 6mA current, -40°C ~ 85°C operating range). No PCB layout changes are required.

Q: What are the limitations of UCC29002DR as a substitute? A: UCC29002DR requires surface-mount PCB implementation and operates within a reduced supply voltage range of 4.375V to 14.25V, compared to the original 4.5V to 35V. This component is not suitable for applications requiring the full voltage range or through-hole mounting.

Q: Why is UC2907NG4 classified as obsolete? A: Obsolete status indicates the component is no longer manufactured. UC2907N (Last Time Buy status) and UCC29002DR (Active status) represent the available alternatives from Texas Instruments.

Q: Are all substitute parts RoHS compliant? A: Yes. UC2907NG4, UC2907N, and UCC29002DR are all ROHS3 compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Q: What is the difference in supply current between UC2907NG4 and UCC29002DR? A: UC2907NG4 requires 6mA supply current, while UCC29002DR requires 2.5mA. The lower current consumption of UCC29002DR may provide power efficiency benefits in applications where the reduced voltage range is acceptable.
