Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AP7362-18SP-13 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters:

Electrical Specifications:

• Output configuration (Positive)
• Output type (Fixed)
• Fixed output voltage (1.8V)
• Maximum output current (1.5A)
• Maximum input voltage (5.5V)
• Supply current (1.3 mA maximum)
• PSRR performance (65dB ~ 61dB at 120Hz ~ 1kHz)
• Control features (Current Limit, Enable)
• Protection features (Over Current, Over Temperature, Short Circuit)
• Operating temperature range (-40°C ~ 85°C)

Mechanical & Packaging Specifications:

• Package type (8-SOIC with exposed pad)
• Package dimensions (0.154", 3.90mm width)
• Mounting type (Surface Mount)
• Packaging format (Tape & Reel)

Compliance & Regulatory:

• RoHS3 compliance
• REACH unaffected status
• Moisture sensitivity level (MSL 1)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both the AP7362-18SP-13 and AP7362A-18SP-13 are active production parts from Diodes Incorporated with identical electrical and mechanical specifications. Selection between these parts is based on the following engineering criteria:

Product Status & Availability: Both parts maintain active production status, ensuring long-term supply continuity and technical support availability. The AP7362A-18SP-13 carries higher inventory levels (5300 units) compared to the AP7362-18SP-13 (2700 units), which may influence lead time considerations for high-volume procurement.

Compliance & Regulatory Alignment: Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for commercial and industrial applications. Moisture sensitivity level MSL 1 indicates unlimited shelf life under standard storage conditions.

Parametric Equivalence: Complete electrical equivalence across all specified parameters—including output voltage, current capacity, PSRR performance, control features, and protection mechanisms—confirms direct substitutability without circuit redesign or performance degradation.

Application Continuity: The identical 8-SOIC package with exposed pad, surface mount configuration, and tape & reel packaging format ensure mechanical and assembly compatibility with existing PCB designs and manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can AP7362A-18SP-13 be used as a direct replacement for AP7362-18SP-13?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output voltage (1.8V fixed), current capacity (1.5A), input voltage rating (5.5V maximum), PSRR performance, control features, protection mechanisms, and operating temperature range. The 8-SOIC package with exposed pad, surface mount configuration, and tape & reel packaging are identical. No circuit modifications are required.

Q: Are there any differences in the package or mounting between these parts?

A: No. Both parts use the identical 8-SOIC (0.154", 3.90mm width) package with exposed pad, surface mount configuration, and tape & reel (TR) packaging format. PCB footprints, assembly processes, and thermal management approaches remain unchanged.

Q: Do both parts meet the same compliance and regulatory standards?

A: Yes. Both AP7362-18SP-13 and AP7362A-18SP-13 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited shelf life) moisture sensitivity rating. Regulatory and environmental compliance is equivalent.

Q: What is the significance of the "A" designation in AP7362A-18SP-13?

A: The "A" designation indicates a product revision or variant within the AP7362 base product family. Both the standard and "A" versions maintain identical electrical and mechanical specifications, confirming full substitutability.

Q: Which part should be selected based on availability?

A: Selection should be based on procurement requirements and lead time constraints. The AP7362A-18SP-13 maintains higher inventory levels (5300 units) compared to AP7362-18SP-13 (2700 units). For applications requiring immediate availability or high-volume orders, the AP7362A-18SP-13 may offer supply advantages. Both parts are active production items with equivalent technical specifications.

Q: Are the PSRR specifications identical between both parts?

A: Yes. Both parts deliver identical Power Supply Rejection Ratio performance of 65dB at 120Hz and 61dB at 1kHz, ensuring equivalent noise rejection and output voltage stability across the specified frequency range.

Q: Can these parts be used interchangeably in existing designs without re-qualification?

A: Yes. Complete parametric equivalence across all electrical, mechanical, and compliance specifications confirms interchangeability. No design changes, PCB modifications, or functional re-testing are required for substitution.
