Key Parameters

Substitute Part Grouping Explanation

Substitution of the BA982-GS08 is determined by the following critical electrical and mechanical parameters:

Voltage Rating: The substitute must support a peak reverse voltage of at least 35V. The PMLL4153,115 provides 50V, which exceeds the minimum requirement and ensures compatibility in circuits designed for the original 35V specification.

Current Rating: The substitute must handle a maximum current of at least 100 mA. The PMLL4153,115 is rated for 200 mA average rectified current, providing adequate margin for the original 100 mA requirement.

Package Compatibility: Both the BA982-GS08 (SOD-80 QuadroMELF) and PMLL4153,115 (DO-213AC, MINI-MELF, SOD-80) share the SOD-80 package designation, enabling direct physical substitution in existing PCB layouts.

Capacitance and Resistance: The substitute's capacitance (2pF @ 0V, 1MHz) and forward voltage characteristics (880 mV @ 50 mA) are within acceptable ranges for standard diode applications, though specific circuit validation is required for high-frequency or precision applications.

Compliance: Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring regulatory and environmental compatibility.

Parameter Comparison

Engineering Selection Recommendations

The PMLL4153,115 is the designated manufacturer-recommended substitute for the BA982-GS08. Selection is justified on the following grounds:

Product Status: The BA982-GS08 is obsolete, while the PMLL4153,115 is active and in production, ensuring long-term availability and supply chain stability.

Regulatory Compliance: Both parts maintain ROHS3 compliance and identical MSL 1 ratings, eliminating compliance barriers to substitution.

Electrical Margin: The PMLL4153,115 exceeds the original specifications in voltage (50V vs. 35V) and current (200 mA vs. 100 mA) ratings, providing design margin for the target application.

Package Compatibility: Both components use SOD-80 packaging, enabling direct PCB layout compatibility without redesign.

Active Supply: The PMLL4153,115 maintains 11,029 pieces in current inventory, supporting immediate procurement and production requirements.

Frequently Asked Questions (FAQ)

Q: Can the PMLL4153,115 be used as a direct replacement for the BA982-GS08 in existing designs?

A: Yes, the PMLL4153,115 is the manufacturer-recommended substitute. Both parts share SOD-80 packaging and meet or exceed the electrical specifications of the original component. No PCB layout modifications are required.

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

A: The PMLL4153,115 provides higher voltage (50V vs. 35V) and current (200 mA vs. 100 mA) ratings, lower operating temperature capability (200°C vs. 150°C), and specified reverse recovery time (4 ns). These represent improvements over the original BA982-GS08 specifications.

Q: Are there any compatibility concerns with the package change from QuadroMELF to MINI-MELF?

A: Both designations refer to the SOD-80 package family. The PMLL4153,115 uses the DO-213AC MINI-MELF variant, which maintains physical and electrical compatibility with the original SOD-80 QuadroMELF package for standard PCB applications.

Q: Does the higher capacitance of the PMLL4153,115 affect high-frequency performance?

A: The PMLL4153,115 capacitance is 2pF at 0V, 1MHz, compared to 1.25pF at 3V, 100MHz for the BA982-GS08. Capacitance values are measured at different bias and frequency conditions. Application-specific circuit validation is required for high-frequency designs operating above 100 MHz.

Q: What is the availability status of both parts?

A: The BA982-GS08 is obsolete with 30,200 pieces in current inventory. The PMLL4153,115 is active in production with 11,029 pieces in inventory, ensuring ongoing supply for new designs and production continuity.
