Substitute Part Grouping Explanation

Substitute parts for the BAP64-05W,115 are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalent (Direct Substitution): BAP64-05W,135 maintains identical electrical specifications including 100V peak reverse voltage, 100 mA maximum current, 240 mW power dissipation, and SC-70 packaging. This part differs only in packaging designation (SOT323-3 vs. SOT323) and represents a direct functional replacement.

Manufacturer Recommended Alternative (Conditional Substitution): BAR6305WH6327XTSA1 from Infineon Technologies operates at reduced voltage (50V peak reverse) and different resistance characteristics (1Ohm @ 10mA vs. 1.35Ohm @ 100mA). This part is suitable only for applications where the 50V voltage rating is sufficient and the lower operating current specification is acceptable. Package type differs (PG-SOT23 vs. SC-70).

Substitution eligibility is determined by matching diode type (PIN - 1 Pair Common Cathode), current rating (100 mA), and package compatibility with circuit board layout requirements.

Engineering Selection Recommendations

BAP64-05W,135: Select this part when BAP64-05W,115 availability is constrained. Both parts maintain identical electrical performance and thermal operating range. Both are ROHS3 compliant with MSL 1 rating and Active product status. Packaging designation difference does not affect functional compatibility.

BAR6305WH6327XTSA1: This part is suitable only when circuit design specifications permit operation at 50V peak reverse voltage instead of 100V. The reduced voltage rating and different resistance measurement conditions (1Ohm @ 10mA vs. 1.35Ohm @ 100mA) indicate different application intent. Package type (PG-SOT23) differs from the original SC-70, requiring board layout verification. All three parts maintain ROHS3 compliance and Active status.

Frequently Asked Questions (FAQ)

Q: Can BAP64-05W,135 be used as a direct replacement for BAP64-05W,115?

A: Yes. Both parts are manufactured by NXP USA Inc. with identical electrical specifications: 100V peak reverse voltage, 100 mA maximum current, 240 mW power dissipation, 0.35pF capacitance, and 1.35Ohm resistance. Both use SC-70 packaging and maintain identical operating temperature range (-65°C to 150°C). The packaging designation difference (SOT323 vs. SOT323-3) does not affect functional compatibility.

Q: When is BAR6305WH6327XTSA1 appropriate as a substitute?

A: BAR6305WH6327XTSA1 is appropriate only when the application circuit is designed for 50V peak reverse voltage operation. This part has lower voltage rating than the original BAP64-05W,115 (50V vs. 100V) and different resistance characteristics. Package type differs (PG-SOT23 vs. SC-70), requiring verification that board layout accommodates the different footprint.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: diode type (PIN - 1 Pair Common Cathode), maximum current rating (100 mA), peak reverse voltage rating, and package type. All three parts share the same diode type and current rating. Voltage rating and package compatibility are critical selection criteria.

Q: Are all three parts RoHS compliant?

A: Yes. BAP64-05W,115, BAP64-05W,135, and BAR6305WH6327XTSA1 are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). All three maintain Active product status.

Q: What is the difference between SC-70 and PG-SOT23 packaging?

A: SC-70 and PG-SOT23 are different package types with different physical dimensions and footprints. SC-70 is the package for BAP64-05W,115 and BAP64-05W,135. PG-SOT23 is the package for BAR6305WH6327XTSA1. Board layout and PCB footprint must be verified before substituting between these package types.
