Substitute Part Grouping Explanation

Substitution of the MGS803 with the MGS801A is based on equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Diode Type: Both parts are Schottky diodes with 1 pair series connection
• Voltage - Peak Reverse (Max): Both rated at 5V (Min)
• Current - Max: Both rated at 50 mA
• Power Dissipation (Max): Both rated at 75 mW
• Operating Temperature Range: Both operate across -65°C ~ 150°C
• Package / Case: Both supplied as Die (Chip)
• Moisture Sensitivity Level: Both classified as MSL 1 (Unlimited)
• Manufacturer: Both manufactured by MACOM Technology Solutions
• Series: Both belong to the MGS8xx series
• Product Status: Both are Active

Secondary Characteristics (Non-Critical for Substitution):

• Capacitance @ Vr, F: MGS803 = 0.06pF @ 0V, 1MHz; MGS801A = 0.075pF @ 0V, 1MHz
• Resistance @ If, F: MGS803 = 7Ohm @ 5mA, 1MHz; MGS801A = 5Ohm @ 5mA, 1MHz

The MGS801A operates within the same electrical envelope as the MGS803 and is suitable for direct substitution in applications where the specified mandatory parameters are the controlling design factors.

Parameter Comparison

Engineering Selection Recommendations

Both the MGS803 and MGS801A are Active products manufactured by MACOM Technology Solutions and carry identical export classification (ECCN: EAR99) and tariff codes (HTSUS: 8541.10.0070). Selection between these parts is determined by application-specific requirements:

Select MGS803 when:

• Lower junction capacitance (0.06pF) is required for high-frequency RF applications
• Higher forward resistance (7Ohm) is acceptable or beneficial for impedance matching

Select MGS801A when:

• Lower forward resistance (5Ohm) is required to minimize conduction losses
• Slightly higher junction capacitance (0.075pF) is acceptable within circuit design parameters

Both parts satisfy identical mandatory electrical specifications: 5V minimum peak reverse voltage, 50 mA maximum current, 75 mW maximum power dissipation, and -65°C to 150°C operating temperature range. Both are supplied as die chips with MSL 1 classification, indicating unlimited shelf life under standard storage conditions.

Frequently Asked Questions (FAQ)

Q: Can MGS801A be used as a direct replacement for MGS803?

A: Yes. Both parts are Schottky diodes with identical diode type (1 pair series connection), voltage rating (5V minimum), current rating (50 mA), power dissipation (75 mW), operating temperature range (-65°C to 150°C), and package type (die chip). The parts differ only in junction capacitance and forward resistance, which are secondary characteristics that do not prevent substitution in applications where the primary electrical specifications are met.

Q: What are the differences between MGS803 and MGS801A?

A: The MGS803 has a junction capacitance of 0.06pF and forward resistance of 7Ohm (both measured at specified conditions). The MGS801A has a junction capacitance of 0.075pF and forward resistance of 5Ohm. These differences may affect high-frequency performance and conduction losses but do not change the fundamental operating envelope or compliance classification of either part.

Q: Are both parts available in the same package?

A: Yes. Both MGS803 and MGS801A are supplied as die chips (bare semiconductor dies). No package conversion is required for substitution.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both parts are classified as MSL 1 (Unlimited), indicating they have unlimited shelf life under standard storage conditions and do not require special moisture control during handling or storage.

Q: What is the current inventory status for these parts?

A: MGS803 has 967 units in stock. MGS801A has 704 units in stock. Both are listed as Active products.

Q: Are there any export or tariff restrictions on these parts?

A: Both parts carry the same export classification (ECCN: EAR99) and tariff code (HTSUS: 8541.10.0070), indicating identical regulatory treatment for international trade purposes.
