Substitute Part Grouping Explanation

Substitution of the MMBD7000_D87Z is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

Diode Configuration: 1 Pair Series Connection
Voltage - DC Reverse (Vr) (Max): 100 V minimum
Current - Average Rectified (Io) (per Diode): 200 mA minimum
Package / Case: TO-236-3, SC-59, SOT-23-3
Mounting Type: Surface Mount

Acceptable Variation Parameters:

Voltage - Forward (Vf) (Max) @ If: Within standard small-signal diode range
Current - Reverse Leakage @ Vr: Variations acceptable within small-signal specifications
Operating Temperature - Junction: Extended ranges acceptable
Product Status: Active status preferred over obsolete

Substitute parts are grouped into two categories:

Direct Equivalents (Identical Electrical Specifications): Parts meeting all critical parameters with matching forward voltage and reverse leakage characteristics.

Parametric Equivalents (Enhanced or Compatible Specifications): Parts exceeding minimum requirements in current rating or temperature range while maintaining package compatibility and core electrical function.

Engineering Selection Recommendations

Tier 1 - Direct Replacements (Recommended for New Designs):

MMBD7000LT1G and MMBD7000LT3G (onsemi) are the primary recommended substitutes. Both parts are active products with identical electrical specifications to the obsolete MMBD7000_D87Z, including 100 V reverse voltage, 200 mA current rating, and 1.1 V forward voltage. These parts feature extended operating temperature range (-55°C to 150°C) and are available in high inventory quantities (245,100 and 10,300 units respectively). Both are ROHS3 compliant.

MMBD7000-E3-08 (Vishay General Semiconductor) provides equivalent electrical performance with active product status and ROHS3 compliance. This part is suitable for applications requiring Vishay component qualification.

CMPD7000 TR PBFREE (Central Semiconductor Corp) offers parametric equivalence with identical electrical specifications and active status. This part provides the highest inventory availability (71,497 units) and is ROHS3 compliant.

Tier 2 - Parametric Equivalents (Application-Dependent):

MMBD7000-TP (Micro Commercial Co) meets all critical parameters with active status and ROHS3 compliance. Forward voltage specification differs (820 mV @ 10 mA versus 1.1 V @ 100 mA), requiring circuit-level verification for applications with tight forward voltage tolerances.

PMBD7000,215 and PMBD7000,235 (Nexperia/NXP) provide enhanced current rating (215 mA versus 200 mA) while maintaining 100 V reverse voltage. Forward voltage is specified at 1.25 V @ 150 mA. Both parts are active and ROHS3 compliant. These parts are suitable for applications requiring margin above the 200 mA specification.

Tier 3 - Limited Availability:

MMBD7000-7-F (Diodes Incorporated) has reduced reverse voltage rating (75 V versus 100 V) but enhanced current capability (300 mA). This part is suitable only for applications with maximum operating voltage of 75 V or less.

SMBD7000E6327HTSA1 (Infineon Technologies) is listed as Last Time Buy status. While electrically equivalent, procurement of this part should be avoided for new designs due to end-of-life status.

Frequently Asked Questions (FAQ)

Q: Can MMBD7000-7-F be used as a direct replacement for MMBD7000_D87Z?

A: MMBD7000-7-F is not a direct replacement. While both parts share the same package (SOT-23-3) and diode configuration, the Diodes Incorporated part has a maximum reverse voltage rating of 75 V compared to 100 V for the original part. Use this substitute only in applications where the maximum operating voltage does not exceed 75 V.

Q: What is the difference between MMBD7000LT1G and MMBD7000LT3G?

A: Both parts are electrically identical with matching specifications for reverse voltage (100 V), current rating (200 mA), forward voltage (1.1 V @ 100 mA), and operating temperature range (-55°C to 150°C). The designations LT1G and LT3G represent different manufacturing date codes or tape reel configurations. Either part is suitable for replacement applications.

Q: Are PMBD7000,215 and PMBD7000,235 interchangeable?

A: Yes, PMBD7000,215 and PMBD7000,235 are electrically equivalent. Both are manufactured by Nexperia/NXP with identical electrical specifications (100 V, 215 mA, 1.25 V @ 150 mA). The part number suffix indicates different packaging or distribution formats. Both are active products suitable for new designs.

Q: Why do some substitute parts have higher reverse leakage current specifications?

A: Reverse leakage current (Ir) variations between parts reflect different manufacturing processes and quality grades. The original MMBD7000_D87Z specifies 500 nA @ 100 V, while some active substitutes specify 3 µA @ 100 V. Both values are within acceptable small-signal diode specifications. Higher leakage does not affect functionality in typical rectification applications but may impact performance in precision analog circuits requiring extremely low leakage.

Q: Is the CMPD7000 TR PBFREE suitable for high-reliability applications?

A: CMPD7000 TR PBFREE meets ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, making it suitable for standard commercial and industrial applications. The part is manufactured by Central Semiconductor Corp with active product status and high inventory availability. Verification against specific high-reliability qualification requirements (such as MIL-PRF or AEC-Q standards) should be performed based on application requirements.

Q: What is the significance of the forward voltage difference between MMBD7000-TP and other substitutes?

A: MMBD7000-TP specifies forward voltage as 820 mV @ 10 mA, while the original part and most substitutes specify 1.1 V @ 100 mA. These measurements are taken at different current levels, making direct comparison difficult. For applications sensitive to forward voltage characteristics, circuit-level testing or datasheet review at the specific operating current is required before substitution.

Q: Can SMBD7000E6327HTSA1 be procured for new designs?

A: SMBD7000E6327HTSA1 is listed as Last Time Buy status, indicating the manufacturer (Infineon Technologies) has announced end-of-life for this product. While electrically equivalent to the original part, procurement for new designs is not recommended. Select from Tier 1 or Tier 2 alternatives with active product status instead.

Q: Are all substitute parts ROHS3 compliant?

A: All active substitute parts listed are ROHS3 compliant. The original MMBD7000_D87Z does not specify ROHS status due to its obsolete classification. All recommended substitutes meet current environmental compliance requirements for commercial and industrial applications.
