APC08F08-J Equivalent & Substitute Parts

Part Overview

The APC08F08-J is a non-isolated Point-of-Load (PoL) module DC-DC converter manufactured by ARTESYN / Advanced Energy. This component delivers 3.3V at 8A output with a 30W power rating, designed for commercial ITE applications. The converter accepts input voltage between 6.5V and 13V and operates across an industrial temperature range of -40°C to 85°C.

The APC08F08-J is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems utilizing this converter topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the APC08F08-J is determined by the following critical parameters:

Functional Compatibility Criteria:

• Non-isolated PoL module topology
• Single output configuration
• Surface mount packaging with compatible footprint dimensions
• Operating temperature range: -40°C to 85°C
• Input voltage range overlap or containment
• Output voltage compatibility or adjustability to 3.3V
• Output current capacity equal to or greater than 8A
• Power rating sufficient for 30W operation

Substitution Logic: The SMT10E-12W3V3J qualifies as a substitute because it maintains the same non-isolated PoL module architecture, operates within the same temperature range, provides single-output configuration, and delivers higher output current capacity (10A) with adjustable output voltage range (0.8V – 3.63V) that includes the required 3.3V setpoint. The input voltage range (10V – 14V) overlaps the upper portion of the APC08F08-J input specification, and the 33W power rating exceeds the 30W requirement.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The APC08F08-J is classified as obsolete, making the SMT10E-12W3V3J the appropriate active alternative from the same manufacturer. The substitute part is in active production status with higher inventory availability (1085 pcs vs. 895 pcs for the main part).

Compliance and Certification: The SMT10E-12W3V3J is RoHS compliant, whereas the APC08F08-J is RoHS non-compliant. For applications subject to RoHS regulations or environmental compliance requirements, the substitute part provides regulatory alignment. Both parts carry the same ECCN (EAR99) and HTSUS (8504.40.9580) classifications.

Electrical Performance: The substitute part exceeds the electrical specifications of the main part in output current capacity (10A vs. 8A) and power rating (33W vs. 30W). The adjustable output voltage range (0.8V – 3.63V) accommodates the fixed 3.3V requirement of the original design. The input voltage range of the substitute (10V – 14V) covers the upper operating window of the main part (6.5V – 13V); applications requiring operation below 10V input require design verification.

Packaging and Thermal Characteristics: Both parts are surface-mount modules with comparable physical dimensions. The substitute features a 6-SMD package versus the 7-SMD package of the main part, with a slightly increased height (8.2mm vs. 7.1mm). Thermal management and PCB layout considerations apply to both designs within the -40°C to 85°C operating range.

Additional Features: The SMT10E-12W3V3J includes remote on/off control, over-temperature protection (OTP), and short-circuit protection (SCP), providing enhanced functionality beyond the main part specification.

Frequently Asked Questions (FAQ)

Q: Can the SMT10E-12W3V3J directly replace the APC08F08-J without design modifications?

A: The SMT10E-12W3V3J is functionally compatible as a substitute. However, the adjustable output voltage of the substitute requires configuration to 3.3V, and the input voltage range difference (10V – 14V vs. 6.5V – 13V) must be evaluated for applications operating below 10V input. The 6-SMD package footprint differs from the 7-SMD package of the original part, requiring PCB layout verification.

Q: What is the significance of the input voltage range difference?

A: The APC08F08-J accepts input voltage from 6.5V to 13V, while the SMT10E-12W3V3J operates from 10V to 14V. The substitute part does not support operation in the 6.5V to 10V input range. Applications requiring full input voltage coverage of the original specification must confirm that system input voltage remains within the 10V to 14V window or select an alternative substitute.

Q: Does the higher output current rating of the substitute part affect compatibility?

A: No. The SMT10E-12W3V3J provides 10A maximum output current compared to the 8A of the APC08F08-J. This represents increased capacity and does not create compatibility issues. The substitute can deliver the same 8A load current required by the original design with additional headroom.

Q: What is the impact of the RoHS compliance difference?

A: The APC08F08-J is RoHS non-compliant, while the SMT10E-12W3V3J is RoHS compliant. For new designs or applications subject to RoHS regulations (EU Directive 2011/65/EU), the substitute part provides regulatory compliance. Existing designs using the obsolete part may continue operation without regulatory change, but migration to the RoHS-compliant substitute is recommended for long-term supply chain sustainability.

Q: How do the package dimensions affect PCB integration?

A: The APC08F08-J measures 33.5mm L × 13.5mm W × 7.1mm H (7-SMD package), while the SMT10E-12W3V3J measures 33.0mm L × 13.5mm W × 8.2mm H (6-SMD package). The length and width are nearly identical, but the substitute is 1.1mm taller. PCB layout and thermal clearance must be verified to accommodate the increased height. The footprint pattern differs due to the 6-SMD versus 7-SMD configuration.

Q: Are there any performance differences in efficiency?

A: The APC08F08-J specifies 92% efficiency. The SMT10E-12W3V3J does not provide an efficiency specification in the available data. Efficiency performance of the substitute should be obtained from the manufacturer datasheet for applications where power dissipation and thermal management are critical design factors.

Q: What additional protection features does the substitute provide?

A: The SMT10E-12W3V3J includes remote on/off control, over-temperature protection (OTP), and short-circuit protection (SCP). These features are not specified for the APC08F08-J. The additional protections enhance system reliability and fault tolerance in the substitute design.
