Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BAP64-03,115 is determined by the following critical parameters:

• Package Compatibility: All substitute parts must use SC-76 or SOD-323 package format to ensure mechanical and electrical compatibility with existing PCB layouts.
• Diode Type: PIN - Single configuration is required for functional equivalence.
• Peak Reverse Voltage: Substitute parts must support the application's voltage requirements. Parts with lower voltage ratings (50V, 75V, 150V) are acceptable only when the circuit design operates within those voltage limits.
• Current Rating: Maximum forward current of 100 mA or higher ensures compatibility with circuit current demands.
• Power Dissipation: Substitute parts with 250 mW or 200 mW ratings represent reduced thermal capability compared to the 500 mW main part and must be evaluated for specific thermal environments.
• Compliance: All substitute parts maintain RoHS3 compliance and MSL Level 1 rating, ensuring regulatory and manufacturing process compatibility.

Parameter Comparison

Engineering Selection Recommendations

BAR6403WE6327HTSA1 (Infineon Technologies) provides the closest electrical match to the BAP64-03,115. This part maintains identical peak reverse voltage (150V), capacitance, and resistance characteristics at the same measurement conditions. The 250 mW power dissipation represents a 50% reduction in thermal capability. This substitute is suitable for applications where circuit design operates within 150V peak reverse voltage limits and thermal dissipation does not exceed 250 mW per device. Both parts maintain active production status, RoHS3 compliance, and MSL Level 1 rating.

BAR6303WE6327HTSA1 (Infineon Technologies) operates at reduced peak reverse voltage (50V) with lower capacitance (0.3pF @ 5V) and reduced power dissipation (250 mW). This part is applicable only to circuits designed for 50V or lower voltage operation. The lower capacitance may provide improved high-frequency performance in specific RF switching applications.

MA4P7433-1141T (MACOM Technology Solutions) operates at 75V peak reverse voltage with higher maximum forward current (150 mA) and extended operating temperature range to 175°C. Power dissipation is limited to 200 mW. This part is suitable for applications requiring higher current handling or elevated temperature operation within the 75V voltage constraint.

All substitute parts maintain full regulatory compliance and manufacturing process compatibility with the original BAP64-03,115 specification.

Frequently Asked Questions (FAQ)

Q: Can BAR6303WE6327HTSA1 replace BAP64-03,115 in all applications?

A: No. BAR6303WE6327HTSA1 is rated for maximum 50V peak reverse voltage, compared to 175V for the BAP64-03,115. Substitution is valid only for circuits designed to operate within 50V voltage limits. Exceeding this voltage rating will result in device failure.

Q: What is the primary difference between BAR6403WE6327HTSA1 and BAP64-03,115?

A: Both parts share identical peak reverse voltage (150V), capacitance, and resistance characteristics. The primary difference is power dissipation: BAR6403WE6327HTSA1 is rated at 250 mW versus 500 mW for BAP64-03,115. Substitution requires verification that circuit thermal dissipation does not exceed 250 mW per device.

Q: Are all substitute parts available in SOD-323 package?

A: Yes. All listed substitute parts use SC-76 or SOD-323 package format, ensuring mechanical compatibility with existing PCB layouts and footprints.

Q: Do substitute parts maintain RoHS3 compliance?

A: Yes. All substitute parts listed are RoHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of BAP64-03,115.

Q: Which substitute part supports the highest operating temperature?

A: MA4P7433-1141T supports maximum operating temperature of 175°C, compared to 150°C for BAP64-03,115 and other substitutes. This part is applicable for high-temperature RF applications within its 75V voltage rating.

Q: Can BAP64-03,115 be replaced with MA4P7433-1141T in high-voltage circuits?

A: No. MA4P7433-1141T is rated for maximum 75V peak reverse voltage. For circuits requiring 175V operation, BAP64-03,115 or BAR6403WE6327HTSA1 (150V) must be used. MA4P7433-1141T is suitable only for applications operating at 75V or lower.
