Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for PIN diodes is determined by the following criteria:

Primary Compatibility Requirements:

• Diode Type: PIN - Single (functional equivalence)
• Package / Case: SC-79 or SOD-523 (mechanical and thermal compatibility)
• Voltage - Peak Reverse (Max): Must equal or exceed 60V
• Current - Max: Must equal or exceed 100 mA
• Power Dissipation (Max): Must equal or exceed 715 mW
• RoHS Status: ROHS3 Compliant (regulatory alignment)
• Moisture Sensitivity Level: MSL 1 (handling compatibility)

Secondary Electrical Parameters:

• Capacitance and Resistance characteristics must fall within acceptable RF performance ranges for the intended application circuit

Both identified substitute parts meet these criteria and are classified as Active products, providing long-term availability and supply chain stability compared to the Obsolete BAP1321-02,115.

Parameter Comparison

Engineering Selection Recommendations

BAR6302VH6327XTSA1 (Infineon Technologies): This substitute operates at 50V peak reverse voltage, which is below the original 60V specification. Selection of this part requires circuit analysis to confirm that the reduced voltage rating does not compromise system performance or safety margins. The part is Active with ROHS3 compliance and MSL 1 rating, ensuring regulatory alignment and supply continuity.

MADP-007433-12790T (MACOM Technology Solutions): This substitute exceeds the original specifications across voltage (75V), current (150 mA), and operating temperature (175°C). The part is Active with ROHS3 compliance and MSL 1 rating. Power dissipation is rated at 200 mW, which is lower than the original 715 mW specification; circuit thermal analysis is required to confirm adequate margin for the intended application.

Both substitutes are available in Active product status, providing superior long-term procurement reliability compared to the Obsolete BAP1321-02,115.

Frequently Asked Questions (FAQ)

Q: Can BAR6302VH6327XTSA1 be used as a direct replacement for BAP1321-02,115?

A: BAR6302VH6327XTSA1 is mechanically compatible (SC-79/SOD-523 package) and functionally equivalent as a PIN diode. However, the 50V peak reverse voltage rating is below the original 60V specification. Substitution is permissible only if circuit operating conditions confirm that the reduced voltage rating maintains adequate safety margin for the application.

Q: What are the thermal considerations when substituting MADP-007433-12790T?

A: MADP-007433-12790T is rated for 200 mW maximum power dissipation, compared to 715 mW for the original BAP1321-02,115. Circuit thermal analysis must confirm that the application's actual power dissipation does not exceed 200 mW. The part's higher operating temperature rating (175°C) provides additional thermal headroom in the junction temperature calculation.

Q: Are all substitute parts RoHS compliant?

A: Yes. BAR6302VH6327XTSA1 and MADP-007433-12790T are both ROHS3 Compliant, matching the regulatory status of the original BAP1321-02,115.

Q: Do the substitute parts have the same moisture sensitivity as the original?

A: Yes. All three parts are rated MSL 1 (Unlimited), indicating identical moisture handling and storage requirements.

Q: What is the primary difference between the two substitute options?

A: BAR6302VH6327XTSA1 offers lower voltage rating (50V) with reduced power dissipation (250 mW). MADP-007433-12790T offers higher voltage rating (75V) and higher current capability (150 mA) but with lower power dissipation (200 mW). Selection depends on the specific electrical requirements of the circuit application.
