Substitute Part Grouping Explanation

Substitution of the HSMS-2820-BLKG is determined by the following criteria:

• Package Compatibility: Both main and substitute parts must use SOT-23-3 (TO-236-3, SC-59) packaging to ensure mechanical and electrical compatibility with existing PCB layouts.
• Diode Type: Schottky - Single configuration is required to maintain functional equivalence.
• Operating Temperature Range: Minimum junction temperature rating of 150°C (TJ) is required.
• Electrical Performance Envelope: Substitute parts must operate within the electrical specifications of the original design. Peak reverse voltage and maximum current ratings of the substitute must meet or exceed the application requirements.

The SMS3922-001LF qualifies as a substitute based on matching package type (SOT-23-3), diode type (Schottky - Single), and operating temperature (150°C TJ). However, the SMS3922-001LF operates at reduced voltage (8V peak reverse) and current (50mA maximum) compared to the HSMS-2820-BLKG, making it suitable only for applications within these lower electrical limits.

Parameter Comparison

Engineering Selection Recommendations

The SMS3922-001LF is an active product from Skyworks Solutions Inc., providing supply continuity for the obsolete HSMS-2820-BLKG. Both devices share identical package specifications (SOT-23-3), operating temperature ratings (150°C TJ), and regulatory compliance status (REACH Unaffected, EAR99 classification).

Selection of SMS3922-001LF as a substitute is appropriate for applications where the circuit design operates within the reduced electrical specifications: peak reverse voltage not exceeding 8V and maximum current not exceeding 50mA. Applications requiring the full 15V reverse voltage capability or 1A current capacity of the original HSMS-2820-BLKG cannot use the SMS3922-001LF without circuit redesign.

The SMS3922-001LF carries RoHS3 compliance certification, whereas the HSMS-2820-BLKG compliance status is not specified in the provided data. Both devices maintain MSL 1 (Unlimited) moisture sensitivity ratings, eliminating moisture-related handling constraints.

Frequently Asked Questions (FAQ)

Q: Can SMS3922-001LF directly replace HSMS-2820-BLKG in all applications?

A: No. The SMS3922-001LF operates at reduced electrical ratings (8V peak reverse voltage, 50mA maximum current) compared to the HSMS-2820-BLKG (15V, 1A). Direct substitution is valid only for circuits designed to operate within these lower electrical limits.

Q: Are the packages physically identical?

A: Yes. Both HSMS-2820-BLKG and SMS3922-001LF use SOT-23-3 (TO-236-3, SC-59) packaging, ensuring identical PCB footprint and pin configuration compatibility.

Q: What is the impact of the product status difference?

A: The HSMS-2820-BLKG is classified as obsolete, indicating discontinued manufacturing and limited availability. The SMS3922-001LF is active, ensuring ongoing supply and manufacturing support from Skyworks Solutions Inc.

Q: Are there regulatory or compliance concerns with substitution?

A: Both parts share identical REACH status (REACH Unaffected) and ECCN classification (EAR99). The SMS3922-001LF includes RoHS3 compliance certification. No regulatory barriers exist for substitution within the electrical operating envelope of the SMS3922-001LF.

Q: How do the electrical characteristics compare?

A: The HSMS-2820-BLKG provides higher voltage and current ratings (15V, 1A) with specified capacitance (1pF @ 0V, 1MHz) and resistance (12Ohm @ 5mA, 1MHz) parameters. The SMS3922-001LF operates at lower ratings (8V, 50mA) with specified power dissipation (75mW) but does not provide capacitance or resistance specifications in the available data.
