APC08G03-J Equivalent & Substitute Parts

Part Overview

The APC08G03-J is a non-isolated Point-of-Load (PoL) module DC-DC converter manufactured by ARTESYN / Advanced Energy. This component delivers a fixed 2.5V output at up to 8A from a 3V to 6V input supply, providing 30W of power in a compact surface-mount package. The APC08G03-J is classified as obsolete, necessitating identification of active equivalent or substitute components for new designs and ongoing production requirements. Substitute parts must maintain functional compatibility while meeting current manufacturing and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the APC08G03-J is determined by the following critical parameters:

Functional Compatibility Criteria:

• Topology: Non-Isolated PoL Module DC-DC Converter
• Single output configuration
• Input voltage range overlap or containment
• Output voltage compatibility with system requirements
• Output current capacity sufficient for load demands
• Power rating adequate for application
• Surface-mount packaging for PCB integration

Regulatory & Compliance Criteria:

• Product status (active vs. obsolete)
• RoHS compliance status
• Operating temperature range suitability

The substitute part SMT10E-05W3V3J shares the same manufacturer, topology, and mounting technology. However, it differs in output voltage (3.3V vs. 2.5V), output current (10A vs. 8A), power rating (36.3W vs. 30W), input voltage range (3V to 5.5V vs. 3V to 6V), and compliance status (RoHS compliant vs. non-compliant). These differences require circuit-level evaluation to determine applicability in specific designs.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The APC08G03-J is classified as obsolete. The SMT10E-05W3V3J is an active product from the same manufacturer, indicating ongoing production support and availability.

Compliance Consideration: The APC08G03-J is RoHS non-compliant, while the SMT10E-05W3V3J is RoHS compliant. Applications subject to RoHS regulations or customer requirements for compliant components necessitate transition to the substitute part.

Thermal Performance: The SMT10E-05W3V3J operates across an extended temperature range (-40°C to 100°C vs. -40°C to 85°C) and delivers higher efficiency (96% vs. 91%), resulting in reduced thermal dissipation and improved performance in temperature-constrained environments.

Electrical Parameter Differences: Direct substitution is not feasible without circuit redesign. The output voltage differs (3.3V vs. 2.5V), requiring verification that downstream components tolerate the higher voltage. The reduced maximum input voltage (5.5V vs. 6V) may impact designs utilizing the full 6V input range. The increased output current capacity (10A vs. 8A) and power rating (36.3W vs. 30W) provide design margin but do not guarantee pin-for-pin compatibility.

Package Consideration: Physical dimensions are similar but not identical. The SMT10E-05W3V3J uses a 6-SMD package versus the 7-SMD package of the APC08G03-J, indicating different pinout configurations. PCB layout modifications are required.

Frequently Asked Questions (FAQ)

Q: Can the SMT10E-05W3V3J be used as a direct replacement for the APC08G03-J?

A: No. While both are non-isolated PoL modules from ARTESYN / Advanced Energy, they differ in output voltage (3.3V vs. 2.5V), package configuration (6-SMD vs. 7-SMD), and pinout. Direct substitution requires circuit redesign and PCB layout modification.

Q: What is the primary reason to transition from the APC08G03-J to the SMT10E-05W3V3J?

A: The APC08G03-J is obsolete with no ongoing manufacturing support. The SMT10E-05W3V3J is an active product with current availability. Additionally, the substitute part is RoHS compliant, addressing regulatory requirements.

Q: Will the SMT10E-05W3V3J fit in the same PCB footprint as the APC08G03-J?

A: No. The SMT10E-05W3V3J has different physical dimensions (1.30" L x 0.53" W x 0.32" H vs. 1.32" L x 0.53" W x 0.28" H) and uses a different SMD package configuration (6-SMD vs. 7-SMD). PCB layout redesign is necessary.

Q: What is the impact of the output voltage difference (3.3V vs. 2.5V)?

A: The 0.8V increase in output voltage requires verification that all downstream components and circuits are rated for 3.3V operation. Voltage-sensitive components may require replacement or circuit modification.

Q: Does the SMT10E-05W3V3J support the full 6V input range of the APC08G03-J?

A: No. The SMT10E-05W3V3J maximum input voltage is 5.5V, compared to 6V for the APC08G03-J. Designs utilizing input voltages between 5.5V and 6V require alternative solutions or input voltage regulation.

Q: What are the advantages of the SMT10E-05W3V3J over the APC08G03-J?

A: The SMT10E-05W3V3J offers higher efficiency (96% vs. 91%), extended operating temperature range (-40°C to 100°C vs. -40°C to 85°C), higher output current capacity (10A vs. 8A), greater power rating (36.3W vs. 30W), RoHS compliance, and active product status with ongoing manufacturer support.

Q: Are there other substitute parts available for the APC08G03-J?

A: Based on the provided data, SMT10E-05W3V3J is the identified substitute. Additional alternatives may exist within ARTESYN / Advanced Energy's product portfolio or from other manufacturers, but such information is not included in this reference.

Q: What is the Moisture Sensitivity Level (MSL) difference between these parts?

A: The APC08G03-J has MSL 1 (unlimited shelf life), while the SMT10E-05W3V3J has MSL 3 (168-hour limit after moisture exposure). The substitute part requires more stringent moisture control during storage and handling.
