UCC2913DG4 Equivalent & Substitute Parts

Part Overview

The UCC2913DG4 is a Hot Swap Controller designed for -48V applications, featuring a single channel with auto retry and UVLO (Under-Voltage Lock-Out) protection. This device is discontinued at DiGi Electronics but remains available through inventory channels with 3,346 pieces in stock. The UCC2913DG4 provides programmable circuit breaker, current limit, and fault timeout functionality for negative floating power supply systems. Due to its discontinued status, identifying equivalent substitute parts is essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the UCC2913DG4 is determined by strict equivalence across the following critical parameters:

• Functional Type: Hot Swap Controller with single channel configuration
• Voltage Application: -48V negative floating supply systems
• Package Compatibility: 8-SOIC form factor (0.154", 3.90mm Width)
• Feature Set: Auto Retry and UVLO protection capabilities
• Programmable Functions: Circuit Breaker, Current Limit, and Fault Timeout
• Operating Temperature: -40°C to 85°C range
• Supply Current: 1 mA specification
• Compliance: ROHS3 and EAR99 classification

The UCC2913D qualifies as a direct manufacturer-recommended substitute based on identical electrical specifications, package geometry, and functional feature parity. Both devices share the same base product number (UCC2913) and are designed for identical -48V hot swap controller applications.

Parameter Comparison

Engineering Selection Recommendations

The UCC2913D is the manufacturer-recommended substitute for the UCC2913DG4. Both devices are functionally equivalent across all specified electrical and mechanical parameters. The primary distinction is product status: the UCC2913DG4 is discontinued at DiGi Electronics, while the UCC2913D maintains active status with higher inventory availability (5,956 pieces versus 3,346 pieces).

For new designs or ongoing procurement, the UCC2913D is the appropriate selection. Both parts comply with ROHS3 and EAR99 classifications, ensuring regulatory alignment. The identical 8-SOIC package geometry permits direct PCB layout compatibility without redesign. Supply current specifications, operating temperature ranges, and programmable feature sets are identical, confirming functional interchangeability in -48V hot swap controller applications.

Frequently Asked Questions (FAQ)

Q: Can the UCC2913D be used as a direct replacement for the UCC2913DG4 on existing PCBs?

A: Yes. Both devices use the 8-SOIC package with identical pin configurations and electrical specifications. No PCB modifications are required for substitution.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is valid when the following parameters match: package type (8-SOIC), channel count (1), voltage application (-48V), feature set (Auto Retry, UVLO), programmable functions (Circuit Breaker, Current Limit, Fault Timeout), operating temperature range (-40°C to 85°C), and supply current (1 mA).

Q: Why is the UCC2913D recommended over the UCC2913DG4?

A: The UCC2913D is actively manufactured and stocked, whereas the UCC2913DG4 is discontinued at DiGi Electronics. Both are electrically and mechanically equivalent, making the UCC2913D the preferred choice for procurement continuity.

Q: Are there compliance differences between these parts?

A: Both parts are classified under EAR99 and HTSUS 8542.39.0001. The UCC2913DG4 is explicitly ROHS3 compliant; the UCC2913D compliance status is not specified in available documentation.

Q: What is the moisture sensitivity level for these devices?

A: The UCC2913DG4 has an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
