APC08M08-J DC DC Converter Equivalent & Substitute Parts

Part Overview

The APC08M08-J is a non-isolated Point-of-Load (PoL) module DC DC converter manufactured by ARTESYN / Advanced Energy. This component delivers 1.5V at 8A maximum output current from a 6.5V to 13V input supply, with 30W power capacity. The device is designed for ITE (Commercial) applications and operates across the industrial temperature range of -40°C to 85°C.

The APC08M08-J is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or field replacement requirements for systems utilizing this converter.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the APC08M08-J is evaluated based on the following critical parameters that define functional equivalence within the non-isolated PoL module category:

Input Voltage Compatibility: The substitute must accept the system input voltage range or a compatible subset. The APC08M08-J operates from 6.5V to 13V; substitute parts must support overlapping or equivalent input ranges.

Output Voltage Capability: The substitute must deliver the required output voltage. The APC08M08-J provides fixed 1.5V output. Substitute parts with programmable or adjustable output voltage ranges that include 1.5V are acceptable.

Output Current and Power Capacity: The substitute must deliver sufficient current and power. The APC08M08-J provides 8A at 1.5V (12W load capacity within 30W module rating). Substitute parts must meet or exceed this current delivery at the required output voltage.

Mounting and Package Form Factor: Both the main part and substitute must be surface-mount devices compatible with standard PCB assembly processes. Physical dimensions should be comparable to permit direct or near-direct board layout substitution.

Operating Temperature Range: The substitute must support the same or wider operating temperature range (-40°C to +85°C) to ensure reliability across all application conditions.

Isolation Type: Both the main part and substitute must be non-isolated topologies to maintain electrical architecture consistency.

The SMT10E-12W3V3J meets these substitution criteria through its adjustable output voltage range (0.8V to 3.63V, which includes 1.5V), higher output current capability (10A), compatible input voltage range (10V to 14V, overlapping with 10V to 13V of the main part), surface-mount package, and matching operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The APC08M08-J is obsolete, making long-term supply unavailable. The SMT10E-12W3V3J is active and in production, ensuring continued availability and support.

Compliance and Certification: The APC08M08-J is RoHS non-compliant. The SMT10E-12W3V3J is RoHS compliant, meeting current environmental and regulatory requirements for new designs and procurement in regulated markets.

Electrical Performance: The SMT10E-12W3V3J provides higher output current (10A versus 8A) and greater power capacity (33W versus 30W), offering improved headroom for load transients and thermal margin. The adjustable output voltage range (0.8V to 3.63V) accommodates the fixed 1.5V requirement of the APC08M08-J through proper configuration.

Input Voltage Range: The SMT10E-12W3V3J input range (10V to 14V) overlaps the upper portion of the APC08M08-J range (6.5V to 13V). Systems operating below 10V input require verification that the substitute can maintain regulation at the lower input boundary of the application.

Physical Form Factor: Both devices are surface-mount modules with comparable footprints (33.5mm × 13.5mm versus 33.0mm × 13.5mm). The SMT10E-12W3V3J is 1.1mm taller (8.2mm versus 7.1mm), which must be verified against PCB assembly clearance constraints.

Additional Features: The SMT10E-12W3V3J includes Remote On/Off control, Over-Temperature Protection (OTP), and Short-Circuit Protection (SCP), providing enhanced functionality not specified in the APC08M08-J.

Frequently Asked Questions (FAQ)

Q: Can the SMT10E-12W3V3J directly replace the APC08M08-J without design modifications?

A: Direct replacement is possible if the system input voltage remains at or above 10V. The SMT10E-12W3V3J requires configuration of the output voltage to 1.5V through its adjustable voltage pins. If the original system operates with input voltages below 10V, the substitute cannot be used without circuit redesign or input voltage conditioning.

Q: What is the significance of the adjustable output voltage range in the SMT10E-12W3V3J?

A: The SMT10E-12W3V3J provides a programmable output voltage from 0.8V to 3.63V, typically set via external resistor dividers or control pins. To match the APC08M08-J fixed 1.5V output, the external voltage-setting network must be configured accordingly. This adds design flexibility but requires proper configuration during board assembly.

Q: Are there package compatibility concerns between the two parts?

A: Both parts are surface-mount modules with nearly identical length and width (33.5mm × 13.5mm versus 33.0mm × 13.5mm). The SMT10E-12W3V3J is 1.1mm taller (8.2mm versus 7.1mm). PCB layout and component clearance must be verified to ensure the taller package does not interfere with adjacent components or enclosure constraints.

Q: Why is RoHS compliance important for this substitution?

A: RoHS compliance indicates the absence of restricted substances (lead, cadmium, mercury, etc.) and reflects current manufacturing standards. The APC08M08-J is non-compliant, while the SMT10E-12W3V3J is compliant. For new designs, procurement in regulated markets, or systems subject to environmental directives, the compliant substitute is required.

Q: What is the impact of the higher output current rating of the SMT10E-12W3V3J?

A: The SMT10E-12W3V3J provides 10A maximum output current compared to 8A in the APC08M08-J. This higher rating provides additional thermal and transient margin. If the original system draws 8A at 1.5V, the substitute operates at 80% of its rated current, improving reliability and reducing thermal stress.

Q: How does the input voltage range difference affect system design?

A: The APC08M08-J accepts 6.5V to 13V input; the SMT10E-12W3V3J accepts 10V to 14V. Systems with input supplies between 6.5V and 10V cannot use the substitute without additional input conditioning or voltage regulation. Systems operating within the 10V to 13V overlap range are fully compatible.

Q: What additional protection features does the SMT10E-12W3V3J provide?

A: The SMT10E-12W3V3J includes Remote On/Off control (enabling external power sequencing), Over-Temperature Protection (OTP, which disables output if internal temperature exceeds limits), and Short-Circuit Protection (SCP, which limits output current during fault conditions). These features enhance system reliability and fault tolerance compared to the APC08M08-J.
