Equivalent & Substitute Parts for MA2Z7850GL

Part Overview

The MA2Z7850GL is a Schottky diode manufactured by Panasonic Electronic Components, rated for 50 V DC reverse voltage and 100 mA average rectified current in a surface mount SMini2-F3 package. This component is classified as obsolete, necessitating identification of equivalent and substitute parts for ongoing design requirements and procurement needs. Substitute parts must maintain functional compatibility within the electrical and mechanical constraints of the original application.

Substitute Part Grouping Explanation

Substitute parts for the MA2Z7850GL are identified based on the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

Technology: Schottky diode
Voltage rating: DC reverse voltage must equal or exceed 50 V
Current rating: Average rectified current must equal or exceed 100 mA
Forward voltage: Maximum forward voltage at rated current must not exceed 550 mV @ 100 mA
Mounting type: Surface mount configuration
Package compatibility: Physical dimensions and pin configuration must accommodate the application

Substitution Logic: Parts are grouped as substitutes when they meet or exceed the electrical specifications of the main part while maintaining surface mount compatibility. Reverse recovery time, reverse leakage current, and capacitance are secondary parameters that influence performance but do not disqualify substitution when primary criteria are satisfied.

Engineering Selection Recommendations

CDBFR0140L (Comchip Technology): This part meets the primary electrical criteria with 40 V reverse voltage rating and 100 mA current capacity. Forward voltage specification matches the main part at 550 mV @ 100 mA. The 40 V rating is below the 50 V specification of the main part, limiting substitution to applications where the actual reverse voltage stress does not exceed 40 V. This part is obsolete, similar to the main part. RoHS3 compliance and REACH unaffected status are documented.

SD101AWS-7-F (Diodes Incorporated): This part does not meet the primary current requirement, rated at 15 mA versus the 100 mA specification of the main part. The 60 V reverse voltage rating exceeds the main part specification. Forward voltage at rated current (1 V @ 15 mA) cannot be directly compared to the main part specification (550 mV @ 100 mA) due to different current levels. This part is active in production status. RoHS3 compliance and REACH unaffected status are documented. Substitution is not recommended for applications requiring 100 mA operation.

Frequently Asked Questions (FAQ)

Q: Can CDBFR0140L replace MA2Z7850GL in all applications?

A: CDBFR0140L is suitable only for applications where the reverse voltage stress does not exceed 40 V. The main part is rated for 50 V. Both parts share identical forward voltage specifications (550 mV @ 100 mA) and current ratings (100 mA), making them electrically compatible within the voltage constraint. Package differences (1005 versus SMini2-F3) must be evaluated for mechanical fit.

Q: Why is SD101AWS-7-F listed as a substitute if it has lower current rating?

A: SD101AWS-7-F is listed in the original substitute field but does not meet the primary current requirement of 100 mA. This part is rated for 15 mA operation only and is not suitable for direct replacement in applications requiring 100 mA. Substitution is limited to circuits where the actual operating current does not exceed 15 mA.

Q: What are the package compatibility considerations?

A: MA2Z7850GL uses SMini2-F3 package (SC-90, SOD-323F). CDBFR0140L uses 1005 (2512 Metric) package. SD101AWS-7-F uses SOD-323 package. Physical dimensions and pin spacing differ between these packages. PCB layout modifications may be required when substituting parts with different package types.

Q: Are all substitute parts currently available?

A: MA2Z7850GL and CDBFR0140L are both classified as obsolete. SD101AWS-7-F is active in production. Inventory availability should be verified with component suppliers before design implementation.

Q: What compliance certifications apply to these parts?

A: CDBFR0140L and SD101AWS-7-F both carry RoHS3 compliance and REACH unaffected status. All three parts are classified under ECCN EAR99 and HTSUS 8541.10.0070. Moisture sensitivity level is 1 (Unlimited) for all parts.
