Engineering Selection Recommendations

The SBR0220T5-7 is the qualified substitute for the obsolete MA2SD190GL based on the following factors:

Electrical Compatibility: Both devices are rated for identical voltage (20 V) and current (200 mA) specifications with matching forward voltage characteristics at rated current. This ensures direct functional replacement in circuit applications.

Package Compatibility: Both components utilize the SOD-523 surface mount package, enabling direct PCB footprint compatibility without layout modifications.

Compliance Status: The SBR0220T5-7 is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements. The MA2SD190GL, as an obsolete part, may present supply chain and compliance challenges.

Product Availability: The SBR0220T5-7 maintains active product status with established supply channels, whereas the MA2SD190GL is obsolete. Selection of the active substitute ensures long-term procurement viability.

Temperature Performance: The SBR0220T5-7 offers an extended operating temperature range (−65°C ~ 150°C) compared to the MA2SD190GL (125°C max), providing additional thermal margin in applications requiring wider temperature operation.

Frequently Asked Questions (FAQ)

Q: Can the SBR0220T5-7 be used as a direct replacement for the MA2SD190GL?

A: Yes. Both devices meet identical electrical specifications (20 V, 200 mA) and share the same SOD-523 surface mount package footprint. No circuit modifications or PCB layout changes are required.

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

A: The primary differences are manufacturer (Panasonic vs. Diodes Incorporated), diode technology (Schottky vs. Super Barrier), product status (obsolete vs. active), and operating temperature range. Electrically and mechanically, they are equivalent for the specified application parameters.

Q: Does the SBR0220T5-7 have better performance characteristics?

A: Both devices share identical forward voltage (470 mV @ 200 mA) and reverse voltage (20 V) ratings. The SBR0220T5-7 offers an extended operating temperature range and active product status, which provides advantages in supply chain continuity and regulatory compliance.

Q: Are there any packaging considerations when substituting these parts?

A: Both components use the SOD-523 package with identical footprints. The SBR0220T5-7 is supplied in Tape & Reel (TR) packaging, which is standard for surface mount production environments. No packaging-related design changes are necessary.

Q: What is the reverse leakage current difference, and does it matter?

A: The MA2SD190GL specifies 15 µA @ 10 V, while the SBR0220T5-7 specifies 40 µA @ 20 V. These measurements are taken at different voltage points, making direct comparison inappropriate. Both values are within acceptable ranges for small signal Schottky and Super Barrier diode applications.

Q: Is the SBR0220T5-7 suitable for high-temperature applications?

A: The SBR0220T5-7 supports operating temperatures up to 150°C, compared to the MA2SD190GL maximum of 125°C. This makes the substitute suitable for applications requiring extended thermal performance.

Q: What compliance certifications apply to the SBR0220T5-7?

A: The SBR0220T5-7 is RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.
