Key Parameters

Substitute Part Grouping Explanation

Substitution within the MSS20 series is determined by strict equivalence across the following critical parameters:

• Diode Type: Schottky - Single
• Package / Case: B10D (mechanical and electrical interface compatibility)
• Voltage - Peak Reverse (Max): 1V
• Current - Max: 35 mA
• Power Dissipation (Max): 100 mW
• Operating Temperature Range: -65°C ~ 150°C
• Product Status: Active

The substitute parts MSS20-143-B10D and MSS20-146-B10D meet all these criteria. Variations in capacitance (0.1pF to 0.12pF @ 0V, 1MHz) fall within acceptable tolerance for RF Schottky diode applications and do not disqualify substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts—MSS20-145-B10D, MSS20-143-B10D, and MSS20-146-B10D—are manufactured by MACOM Technology Solutions and maintain active product status. The MSS20-145-B10D and MSS20-146-B10D are electrically identical with matching capacitance specifications (0.12pF @ 0V, 1MHz). The MSS20-143-B10D exhibits a lower capacitance value (0.1pF @ 0V, 1MHz) while maintaining all other electrical and thermal parameters. All parts are MSL 1 rated and suitable for unlimited moisture exposure conditions. Selection between these parts depends on application-specific capacitance requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can MSS20-143-B10D be used in place of MSS20-145-B10D?

A: Yes. Both parts are Schottky single diodes in the B10D package with identical voltage, current, power dissipation, and temperature specifications. The capacitance difference (0.1pF versus 0.12pF @ 0V, 1MHz) represents a 16.7% variation within acceptable RF diode tolerance ranges for most applications.

Q: Can MSS20-146-B10D be used in place of MSS20-145-B10D?

A: Yes. MSS20-146-B10D is electrically and mechanically equivalent to MSS20-145-B10D, with identical capacitance (0.12pF @ 0V, 1MHz) and all other critical parameters.

Q: Are there package compatibility concerns between these parts?

A: No. All three parts use the B10D package specification, ensuring mechanical and electrical interface compatibility in identical PCB footprints and assembly processes.

Q: What is the significance of the capacitance variation between MSS20-143-B10D and the other parts?

A: Capacitance variation in RF Schottky diodes affects impedance matching and frequency response characteristics. The 0.1pF value in MSS20-143-B10D versus 0.12pF in MSS20-145-B10D and MSS20-146-B10D may influence circuit tuning requirements in high-frequency applications. Circuit-level analysis is necessary to determine if this variation impacts performance.

Q: Are all substitute parts RoHS compliant?

A: MSS20-145-B10D is explicitly ROHS3 compliant. RoHS compliance status for MSS20-143-B10D and MSS20-146-B10D is not specified in the provided data.

Q: What is the moisture sensitivity rating for these parts?

A: All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
