Substitute Part Grouping Explanation

Substitute parts are grouped into two categories based on packaging configuration and availability:

Grouping Criteria:

• Voltage - Isolation: 5000Vrms (mandatory match)
• Number of Channels: 1 (mandatory match)
• Output Type: Transistor or Transistor with Base (functionally compatible)
• Current Transfer Ratio: 15% @ 16mA minimum (mandatory match)
• Voltage - Output (Max): 35V (mandatory match)
• Current - Output / Channel: 8mA (mandatory match)
• Operating Temperature Range: -55°C ~ 110°C (mandatory match)
• Package / Case: 6-SOIC footprint (mandatory match)
• Series: NEPOC (mandatory match)

Direct Manufacturer Substitutes (identical to main part or minimal variation):

• PS8302L-V-AX: Output Type variant (Transistor with Base)
• PS8302L2-AX: Identical electrical specifications
• PS8302L2-V-AX: Output Type variant with identical electrical specifications

Parametric Equivalents (tape & reel packaging, active production):

• PS8302L-E3-AX: Tape & Reel packaging of main part specification
• PS8302L-V-E3-AX: Tape & Reel with Transistor output variant
• PS8302L2-E3-AX: Tape & Reel with identical specifications
• PS8302L2-V-E3-AX: Tape & Reel with Transistor output variant

All parts maintain identical electrical performance and are mechanically compatible within the 6-SOIC footprint.

Parameter Comparison

Engineering Selection Recommendations

For discontinued part replacement: Select from Renesas Electronics Corporation active product alternatives. All listed substitutes maintain full compliance with RoHS3 and REACH requirements, matching the regulatory posture of the original PS8302L-E3-AX.

Packaging considerations: Strip packaging (PS8302L2-AX, PS8302L-V-AX, PS8302L2-V-AX) is suitable for lower-volume applications or mixed component sourcing. Tape & Reel packaging (E3-AX suffix variants) is specified for high-volume manufacturing and automated assembly lines.

Output type selection: Standard Transistor output (PS8302L2-AX, PS8302L-E3-AX, PS8302L2-E3-AX) provides direct collector-emitter switching. Transistor with Base variants (PS8302L-V-AX, PS8302L-V-E3-AX, PS8302L2-V-E3-AX) expose base pin for alternative biasing schemes.

Inventory availability: Tape & Reel variants (E3-AX suffix) have higher inventory levels suitable for production commitments. All alternatives are current production parts from Renesas, ensuring long-term supply stability.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the PS8302L-E3-AX? A: Electrical substitution requires matching isolation voltage (5000Vrms), single channel configuration, identical current transfer ratio (15% @ 16mA), 35V maximum output voltage, and 8mA output current. All candidates must share the 6-SOIC package footprint and -55°C to 110°C operating temperature range.

Q: What is the difference between Transistor and Transistor with Base output types? A: Transistor output provides standard collector-emitter switching. Transistor with Base variants expose the base pin, allowing external base drive and alternative biasing configurations. Both types are electrically equivalent for standard switching applications.

Q: Is Strip packaging compatible with Tape & Reel packaging? A: Both packaging types contain identical semiconductor dies and electrical specifications. Strip packaging is conventional for component distribution and lower quantities. Tape & Reel packaging is specified for automated pick-and-place assembly and higher production volumes. Mechanical compatibility within PCB assembly is identical.

Q: Are all listed substitutes ROHS3 and REACH compliant? A: Yes. All alternative parts maintain ROHS3 Compliant status and REACH Unaffected designation, matching the regulatory compliance of the original PS8302L-E3-AX.

Q: Can I use PS8302L2 variants as direct replacements for PS8302L variants? A: Yes. The PS8302L and PS8302L2 product lines maintain identical electrical parameters within the specified ranges. The secondary digit variation indicates manufacturing revision; both are functionally interchangeable for the specified performance envelope.

Q: What is the MSL rating, and does it affect substitution? A: MSL (Moisture Sensitivity Level) 1 indicates unlimited moisture tolerance. All listed parts carry MSL 1, requiring no special moisture protection or bake procedures during standard PCB assembly.
