Key Parameters

Substitute Part Grouping Explanation

Substitution of the BA682-GS08 is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the DO-213AC / MINI-MELF / SOD-80 surface mount package to ensure mechanical and electrical compatibility with existing PCB layouts.

Voltage Rating: The substitute must meet or exceed the 35V peak reverse voltage requirement of the BA682-GS08 to maintain circuit protection and reliability margins.

Current Capability: The substitute must support the maximum current demands of the application. The BA682-GS08 specifies 100 mA maximum current.

Diode Classification: The substitute must function as a general-purpose or PIN diode suitable for RF applications, maintaining compatibility with the intended switching or attenuation function.

Compliance & Availability: The substitute must maintain RoHS3 compliance and demonstrate active production status or confirmed inventory to ensure long-term supply chain viability.

The PMLL4153,115 meets these substitution criteria through equivalent package geometry, superior voltage rating (50V), higher current capacity (200mA), active product status, and confirmed RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

The PMLL4153,115 is the qualified substitute for the obsolete BA682-GS08 based on the following engineering criteria:

Package Equivalence: Both parts utilize the DO-213AC / MINI-MELF / SOD-80 surface mount package, ensuring direct PCB footprint compatibility without layout modifications.

Electrical Superiority: The PMLL4153,115 exceeds the BA682-GS08 specifications across all critical parameters. The 50V reverse voltage rating provides a 43% margin above the 35V requirement, while the 200mA current capacity doubles the 100mA specification of the original part. These enhanced ratings ensure reliable operation under worst-case circuit conditions.

Compliance & Supply Continuity: The PMLL4153,115 maintains ROHS3 compliance and MSL-1 moisture sensitivity rating, matching the environmental and regulatory requirements of the BA682-GS08. Active production status and confirmed inventory (11029 Pcs) guarantee long-term supply chain availability, eliminating obsolescence risk.

Thermal Performance: The PMLL4153,115 supports a maximum junction temperature of 200°C, compared to 150°C for the BA682-GS08, providing enhanced thermal margin for high-reliability applications.

Frequently Asked Questions (FAQ)

Q: Can the PMLL4153,115 be used as a direct replacement for the BA682-GS08 without PCB modifications?

A: Yes. Both parts share identical package geometry (DO-213AC / MINI-MELF / SOD-80), enabling direct footprint compatibility. No PCB layout changes are required.

Q: What are the key differences between these parts?

A: The PMLL4153,115 provides higher voltage rating (50V vs. 35V), greater current capacity (200mA vs. 100mA), and higher maximum junction temperature (200°C vs. 150°C). These represent performance enhancements rather than functional differences.

Q: Is the PMLL4153,115 suitable for RF applications like the BA682-GS08?

A: The PMLL4153,115 is classified as a general-purpose diode with small-signal characteristics (≤200mA). It is suitable for RF switching and attenuation applications within the specified current and voltage parameters.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the BA682-GS08 and PMLL4153,115 are ROHS3 compliant with MSL-1 moisture sensitivity rating, meeting identical environmental and regulatory requirements.

Q: What is the supply status of each part?

A: The BA682-GS08 is obsolete with no active production. The PMLL4153,115 is in active production with confirmed inventory of 11029 pieces, ensuring reliable long-term availability.

Q: Are there any capacitance or resistance differences that affect circuit performance?

A: The PMLL4153,115 exhibits slightly higher capacitance (2pF @ 0V, 1MHz vs. 1.25pF @ 3V, 100MHz) due to measurement conditions and frequency differences. Both values are typical for small-signal diodes and do not preclude substitution in standard RF applications.
