Substitute Part Grouping Explanation

Substitution of the MA2C72300F is determined by strict equivalence across the following critical parameters:

Mandatory Matching Criteria:

Voltage - DC Reverse (Vr) (Max): 30V
Current - Average Rectified (Io): 200mA
Mounting Type: Through Hole
Package / Case: DO-34 Axial
Technology: Schottky

Allowable Parameter Variance: Substitute parts must maintain or exceed the voltage and current ratings. Forward voltage (Vf), reverse recovery time (trr), reverse leakage current, and junction temperature may vary within the constraints of the application circuit. The BAT85,113 from Nexperia USA Inc. satisfies all mandatory matching criteria and is classified as an active product, providing long-term availability and supply chain stability.

Engineering Selection Recommendations

The BAT85,113 from Nexperia USA Inc. is the qualified substitute for the obsolete MA2C72300F. Selection is based on the following engineering criteria:

Electrical Equivalence: Both parts share identical voltage and current ratings (30V, 200mA), ensuring functional compatibility in circuits designed for the MA2C72300F.

Package Compatibility: Both components use the DO-34 axial through-hole package, permitting direct mechanical substitution without PCB redesign.

Product Status and Supply: The BAT85,113 is classified as active with 22,058 pcs in inventory, providing immediate availability and long-term supply chain continuity. The MA2C72300F, though currently in stock (778 pcs), is obsolete and subject to discontinuation.

Compliance and Certifications: The BAT85,113 is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements. Both parts carry EAR99 ECCN classification and share identical HTSUS codes.

Thermal Consideration: The MA2C72300F operates to 150°C junction temperature, while the BAT85,113 is rated to 125°C. Applications operating near or above 125°C junction temperature require thermal analysis to confirm BAT85,113 suitability.

Secondary Parameter Differences: The BAT85,113 exhibits lower reverse leakage current (2 µA vs. 15 µA) and lower capacitance (10 pF vs. 20 pF), which may improve performance in high-frequency or low-leakage applications. Reverse recovery time is longer (4 ns vs. 2 ns), which may affect switching speed in time-critical circuits.

Frequently Asked Questions (FAQ)

Q: Can the BAT85,113 be used as a direct replacement for the MA2C72300F?

A: Yes. Both parts are Schottky diodes with identical 30V reverse voltage and 200mA current ratings in DO-34 axial packages. Direct substitution is electrically and mechanically compatible for applications operating within the BAT85,113 thermal limits (125°C maximum junction temperature).

Q: What are the key differences between these two parts?

A: The primary differences are product status (BAT85,113 is active; MA2C72300F is obsolete), maximum junction temperature (125°C vs. 150°C), reverse recovery time (4 ns vs. 2 ns), reverse leakage current (2 µA vs. 15 µA), and capacitance (10 pF vs. 20 pF). These differences are secondary to the core voltage and current specifications.

Q: Are there thermal concerns when substituting the BAT85,113 for the MA2C72300F?

A: The BAT85,113 has a lower maximum junction temperature rating (125°C vs. 150°C). Applications designed for the MA2C72300F operating near 150°C require thermal verification to ensure the BAT85,113 remains within its 125°C limit under worst-case conditions.

Q: Do both parts use the same package?

A: Yes. Both the MA2C72300F and BAT85,113 use the DO-34 axial through-hole package (DO-204AG). No PCB layout modifications are required for substitution.

Q: What is the inventory status of each part?

A: The MA2C72300F has 778 pcs in stock but is classified as obsolete. The BAT85,113 has 22,058 pcs in stock and is actively manufactured, providing superior long-term availability.

Q: Are there compliance or regulatory differences?

A: Both parts carry EAR99 ECCN classification and identical HTSUS codes. The BAT85,113 is RoHS3 compliant and REACH unaffected, meeting current regulatory standards. Compliance status for the MA2C72300F is not specified in the provided data.

Q: How do the electrical characteristics compare in practical applications?

A: The BAT85,113 exhibits lower reverse leakage (2 µA vs. 15 µA) and lower capacitance (10 pF vs. 20 pF), which may provide performance benefits in low-leakage or high-frequency circuits. The longer reverse recovery time (4 ns vs. 2 ns) may affect switching speed in time-critical applications. Forward voltage characteristics are measured at different current levels and require circuit-specific analysis.

Q: Should I test the BAT85,113 before full production substitution?

A: Substitution decisions should be based on the electrical and thermal requirements of the specific application. The provided parameters establish functional equivalence; application-specific validation follows standard engineering practice.
