Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete AO3496 is based on the following criteria derived from the provided parameters:

Primary Substitution Criteria:

• FET Type: N-Channel configuration
• Package Type: SOT-23-3 surface mount
• Manufacturer: Alpha & Omega Semiconductor Inc. (same manufacturer preferred for consistency)
• Compliance: ROHS3 Compliant and REACH Unaffected status maintained
• Moisture Sensitivity: MSL 1 (Unlimited) classification

The substitute part AOSS32136C meets all these criteria. Both components are N-Channel MOSFETs from the same manufacturer in compatible SOT-23 surface mount packaging with identical compliance certifications. The AOSS32136C is in active production status, ensuring long-term availability and supply chain reliability.

Engineering Selection Recommendations

The AOSS32136C is the designated substitute for the obsolete AO3496 based on the following engineering factors:

Product Status Alignment: The AOSS32136C maintains active production status, ensuring continuous availability and supply chain stability. This addresses the primary limitation of the AO3496, which is no longer manufactured.

Compliance Continuity: Both components maintain identical ROHS3 compliance and REACH Unaffected status, ensuring regulatory requirements are satisfied in applications requiring these certifications.

Packaging Compatibility: The SOT-23-3 surface mount package of the AOSS32136C is mechanically and electrically compatible with the AO3496 SOT-23 footprint, allowing direct board-level substitution without layout modifications.

Manufacturer Consistency: Both components are manufactured by Alpha & Omega Semiconductor Inc., maintaining supply chain consistency and quality assurance protocols.

Moisture Sensitivity Classification: The MSL 1 (Unlimited) rating of the AOSS32136C matches the AO3496, eliminating moisture handling and storage requirement changes.

Frequently Asked Questions (FAQ)
