Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMBD1505A_D87Z is determined by the following critical parameters:

Primary Substitution Criteria:

• Diode Configuration: 1 Pair Common Anode (pinout compatibility)
• Package / Case: TO-236-3, SC-59, SOT-23-3 (mechanical and thermal compatibility)
• Voltage - DC Reverse (Vr) (Max): Minimum 200 V (electrical stress rating)
• Current - Average Rectified (Io) (per Diode): Minimum 200 mA (current handling capacity)
• Mounting Type: Surface Mount (assembly process compatibility)

Parametric Equivalent Classification: Parts meeting all primary criteria with identical electrical specifications are classified as parametric equivalents and provide direct functional replacement.

Similar Part Classification: Parts meeting primary criteria but with variations in secondary parameters (forward voltage, reverse leakage, temperature range, or speed characteristics) are classified as similar parts. These require application-level verification to confirm suitability.

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalent (Direct Replacement):

The MMBD1505A manufactured by Fairchild Semiconductor is a parametric equivalent to the MMBD1505A_D87Z. This part maintains identical electrical specifications across all critical parameters: 200 V reverse voltage, 200 mA average rectified current, 1.1 V forward voltage at 200 mA, and identical reverse leakage characteristics. The Fairchild MMBD1505A is classified as Active, ensuring continued availability and supply chain stability. This part is the preferred substitute for direct functional replacement.

Similar Parts (Application-Dependent Selection):

The MMBD1505-TP (Micro Commercial Co) is a similar part with the same current rating and forward voltage characteristics but features a reduced reverse voltage rating of 180 V compared to the 200 V specification of the original part. This part is suitable only for applications where the circuit operates at or below 180 V reverse bias conditions. The MMBD1505-TP is classified as Active and is available in Tape & Reel packaging.

The MMBD3004A-7-F (Diodes Incorporated) is a similar part with enhanced voltage rating (300 V) and current capacity (225 mA), but employs Fast Recovery technology with a 50 ns reverse recovery time, differing from the Standard technology of the original part. This part is classified as Obsolete. The higher voltage and current ratings provide design margin, but the different speed characteristics require verification for timing-sensitive applications.

Compliance and Certification:

All substitute parts maintain identical Moisture Sensitivity Level (MSL) classification of 1 (Unlimited), REACH Unaffected status, and ECCN/HTSUS classifications, ensuring regulatory compliance equivalence.

Frequently Asked Questions (FAQ)

Q: Can the MMBD1505A from Fairchild Semiconductor be used as a direct replacement for the MMBD1505A_D87Z?

A: Yes. The Fairchild MMBD1505A is a parametric equivalent with identical electrical specifications, package configuration, and mounting type. No circuit modifications are required.

Q: What is the key difference between the MMBD1505-TP and the original MMBD1505A_D87Z?

A: The MMBD1505-TP has a reduced reverse voltage rating of 180 V compared to 200 V in the original part. It is suitable only for applications operating at or below 180 V reverse bias. Additionally, the forward voltage is specified at 1.3 V versus 1.1 V for the original part.

Q: Is the MMBD3004A-7-F a suitable replacement for the MMBD1505A_D87Z?

A: The MMBD3004A-7-F shares the same package and diode configuration but differs in technology (Fast Recovery versus Standard), reverse voltage (300 V versus 200 V), and current capacity (225 mA versus 200 mA). The higher ratings provide design margin, but the different speed characteristics must be evaluated for the specific application.

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

A: All substitute parts use the same TO-236-3 (SC-59, SOT-23-3) package for mechanical and thermal compatibility. However, packaging formats differ: the Fairchild MMBD1505A packaging is not specified, the MMBD1505-TP is supplied in Tape & Reel (TR) format, and the MMBD3004A-7-F is supplied in Cut Tape (CT) format. Verify packaging availability with your supplier for production requirements.

Q: What is the product status of each substitute part?

A: The Fairchild MMBD1505A is classified as Active, ensuring long-term availability. The MMBD1505-TP is also Active. Both the original MMBD1505A_D87Z and the MMBD3004A-7-F are classified as Obsolete.

Q: Do all parts meet the same moisture sensitivity requirements?

A: Yes. All parts, including the original and all substitutes, are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.
