Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MSS20-142-0402 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Diode Type: Schottky - Single
• Voltage - Peak Reverse (Max): 1V
• Current - Max: 35 mA
• Power Dissipation (Max): 100 mW
• Package / Case: 0402 (1005 Metric)
• Operating Temperature Range: -65°C ~ 150°C
• Manufacturer: MACOM Technology Solutions
• Product Status: Active

Variable Parameters (Non-Critical for Substitution):

• Capacitance @ Vr, F: Varies within acceptable range (0.15pF to 0.2pF @ 500mV, 1MHz)
• Packaging format: Tray or alternative supplier packaging

The substitute parts MSS20-141-0402 and MSS20-145-0402 meet all mandatory matching criteria and differ only in junction capacitance specifications, which remain within the operational envelope for RF Schottky diode applications in this class.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—MSS20-142-0402, MSS20-141-0402, and MSS20-145-0402—are Active products from MACOM Technology Solutions with identical electrical ratings and thermal specifications. Selection between these parts is based on application-specific capacitance requirements and inventory availability.

MSS20-142-0402 (Primary): 0.18pF junction capacitance provides mid-range performance for general RF Schottky applications.

MSS20-141-0402 (Substitute): 0.15pF junction capacitance offers lower capacitance for applications requiring reduced parasitic effects at higher frequencies.

MSS20-145-0402 (Substitute): 0.2pF junction capacitance provides slightly higher capacitance tolerance for applications with less stringent frequency response requirements.

All parts comply with identical export control classifications (EAR99) and tariff codes (8541.10.0070), ensuring regulatory equivalence. Moisture sensitivity level 1 (Unlimited) indicates no special handling requirements for any variant.

Frequently Asked Questions (FAQ)

Q: Can MSS20-141-0402 or MSS20-145-0402 be used as direct replacements for MSS20-142-0402?

A: Yes. All three parts share identical voltage, current, power dissipation, temperature range, and package specifications. The only difference is junction capacitance (0.15pF, 0.18pF, or 0.2pF @ 500mV, 1MHz). Selection depends on whether your circuit design requires a specific capacitance value.

Q: What is the significance of the capacitance difference between these parts?

A: Junction capacitance affects RF performance at high frequencies. Lower capacitance (MSS20-141-0402) reduces parasitic effects and improves performance at higher frequencies. Higher capacitance (MSS20-145-0402) may be acceptable in lower-frequency applications or where capacitance tolerance is less critical.

Q: Are there packaging differences between these substitute parts?

A: The main part (MSS20-142-0402) is specified with no packaging format noted. Substitute parts MSS20-141-0402 and MSS20-145-0402 are supplied in Tray packaging. All three use the same 0402 (1005 Metric) surface-mount package format.

Q: Do these parts require different handling or storage procedures?

A: No. All three parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control or baking requirements during storage or handling.

Q: Are all three parts currently in stock?

A: Inventory status varies. MSS20-142-0402 has 965 units, MSS20-141-0402 has 888 units, and MSS20-145-0402 has 1082 units available as new original stock.

Q: Can these parts be used interchangeably in production?

A: Interchangeability depends on circuit design specifications. If your design specifies a particular capacitance value, use only the matching part number. If capacitance tolerance is not specified, any of the three parts can be used provided the application operates within the specified voltage, current, and temperature ranges.
