Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMBD1504A_D87Z is determined by the following critical parameters: diode configuration (1 Pair Common Cathode), package type (TO-236-3, SC-59, SOT-23-3), voltage rating (200 V DC reverse), current rating (200 mA average rectified), and mounting technology (Surface Mount). Substitute parts are grouped into two categories based on electrical equivalence:

Parametric Equivalent (Full Compatibility): Parts that match all key electrical specifications and package requirements without operational limitations.

Similar Parts (Conditional Compatibility): Parts that share the same package and configuration but differ in voltage rating, current rating, or speed characteristics. These require application-level verification to confirm suitability.

The following parameters define substitution boundaries:

• Diode Configuration: Must be 1 Pair Common Cathode
• Package: Must be TO-236-3, SC-59, SOT-23-3 (Surface Mount)
• Voltage Rating: 200 V minimum for direct equivalence
• Current Rating: 200 mA minimum for direct equivalence
• Mounting Type: Surface Mount required

Parameter Comparison

Engineering Selection Recommendations

MMBD1504A (onsemi): This part is the direct parametric equivalent to the MMBD1504A_D87Z. It maintains identical electrical specifications across all critical parameters: 200 V DC reverse voltage, 200 mA average rectified current, 1.1 V forward voltage at 200 mA, and 10 nA reverse leakage at 180 V. The MMBD1504A is classified as Active with ROHS3 compliance and unlimited moisture sensitivity rating. This component is the preferred substitute for direct replacement in existing designs.

BAV23C-E3-08 (Vishay General Semiconductor - Diodes Division): This part matches the voltage rating (200 V) and current rating (200 mA) of the main part and shares the identical package configuration. The BAV23C-E3-08 is classified as Active with ROHS3 compliance. Differences include forward voltage of 1.25 V at 200 mA (versus 1.1 V) and fast recovery speed characteristics with 50 ns reverse recovery time. This part is suitable for applications where fast recovery performance is beneficial or required.

PMBD6100,215 (Nexperia USA Inc.): This part shares the same package and diode configuration but operates at a reduced voltage rating of 70 V DC reverse (versus 200 V). Current rating is 215 mA (DC), exceeding the main part specification. The PMBD6100,215 is classified as Active with ROHS3 compliance and features fast recovery speed with 4 ns reverse recovery time. This part is suitable only for applications where the 70 V voltage rating is sufficient.

PMBD7100,215 (Nexperia USA Inc.): This part shares the same package and diode configuration but operates at a reduced voltage rating of 100 V DC reverse (versus 200 V). Current rating is 215 mA (DC), exceeding the main part specification. The PMBD7100,215 is classified as Active with ROHS3 compliance and features fast recovery speed with 4 ns reverse recovery time. This part is suitable only for applications where the 100 V voltage rating is sufficient.

Frequently Asked Questions (FAQ)

Q: Can MMBD1504A be used as a direct replacement for MMBD1504A_D87Z?

A: Yes. The MMBD1504A is a parametric equivalent with identical electrical specifications and package configuration. The primary difference is product status: MMBD1504A_D87Z is Obsolete while MMBD1504A is Active. Both parts maintain 200 V DC reverse voltage, 200 mA average rectified current, and 1.1 V forward voltage at 200 mA. MMBD1504A includes ROHS3 compliance certification.

Q: What is the difference between the main part and BAV23C-E3-08?

A: Both parts share 200 V voltage rating, 200 mA current rating, and identical package (TO-236-3, SC-59, SOT-23-3). The BAV23C-E3-08 has a forward voltage of 1.25 V at 200 mA (compared to 1.1 V for the main part) and incorporates fast recovery technology with 50 ns reverse recovery time. The main part is classified as Small Signal with any speed. BAV23C-E3-08 is suitable for applications requiring faster switching characteristics.

Q: Can PMBD6100,215 or PMBD7100,215 replace the MMBD1504A_D87Z?

A: These parts share the same package and diode configuration but have reduced voltage ratings. PMBD6100,215 is rated for 70 V (versus 200 V required), and PMBD7100,215 is rated for 100 V (versus 200 V required). These parts are suitable only for applications where the lower voltage rating meets circuit requirements. Both offer higher current ratings (215 mA DC) and fast recovery characteristics.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts are housed in the TO-236-3, SC-59, SOT-23-3 Surface Mount package. Packaging format differences exist: MMBD1504A_D87Z packaging is not specified, while MMBD1504A, BAV23C-E3-08, PMBD6100,215, and PMBD7100,215 are available in Tape & Reel (TR) format. All parts maintain identical footprint and pin configuration for PCB compatibility.

Q: What compliance certifications apply to substitute parts?

A: MMBD1504A, BAV23C-E3-08, PMBD6100,215, and PMBD7100,215 are all ROHS3 compliant and REACH Unaffected. All parts maintain Moisture Sensitivity Level 1 (Unlimited). These certifications ensure compatibility with current environmental and regulatory requirements for electronic component procurement and assembly.

Q: How do reverse leakage characteristics compare across substitute options?

A: The main part MMBD1504A_D87Z specifies 10 nA reverse leakage at 180 V. MMBD1504A maintains this specification at 10 nA @ 180 V. BAV23C-E3-08 specifies 100 nA @ 200 V. PMBD6100,215 specifies 100 nA @ 50 V. PMBD7100,215 specifies 2.5 µA @ 100 V. Lower reverse leakage values indicate reduced off-state current and are preferred for low-power or high-impedance applications.

Q: What is the inventory status of substitute parts?

A: MMBD1504A has 44,100 pieces in stock. BAV23C-E3-08 has 10,225 pieces in stock. PMBD6100,215 has 39,300 pieces in stock. PMBD7100,215 has 4,300 pieces in stock. All substitute parts are classified as Active products with current manufacturing support.
