Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete US1GE-TP is determined by electrical and mechanical parameter equivalence. The substitute part must satisfy the following criteria:

Electrical Parameters (Critical):

• Voltage - DC Reverse (Vr) (Max): 400 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.4 V @ 1 A
• Reverse Recovery Time (trr): 50 ns
• Current - Reverse Leakage @ Vr: 10 µA @ 400 V
• Capacitance @ Vr, F: 20 pF @ 4 V, 1 MHz
• Technology: Standard
• Speed: Fast Recovery ≤ 500 ns, > 200 mA (Io)

Mechanical Parameters (Critical):

• Mounting Type: Surface Mount
• Package / Case: DO-214AC, SMA

The substitute part US1G-TP shares the same base product number (US1G) and maintains identical electrical specifications while offering active product status and extended operating temperature range.

Engineering Selection Recommendations

The US1G-TP is the direct substitute for the obsolete US1GE-TP. Both parts are manufactured by Micro Commercial Co and share identical electrical and mechanical specifications across all critical parameters. The US1G-TP offers the following advantages:

Product Status: The US1G-TP maintains active product status, ensuring long-term availability and supply chain continuity compared to the obsolete US1GE-TP.

Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for electronic component procurement.

Operating Temperature Range: The US1G-TP extends the operating temperature range to -65°C ~ 175°C, providing broader thermal performance capability compared to the US1GE-TP range of -50°C ~ 150°C.

Packaging: The US1G-TP is supplied in Tape & Reel (TR) packaging, which is standard for high-volume surface mount assembly operations.

Frequently Asked Questions (FAQ)

Q: Can US1G-TP directly replace US1GE-TP in existing designs?

A: Yes. The US1G-TP is electrically and mechanically equivalent to the US1GE-TP across all specified parameters, including voltage rating, current rating, forward voltage drop, reverse recovery time, leakage current, and capacitance. Both components use the DO-214AC (SMA) surface mount package.

Q: What is the difference between US1GE-TP and US1G-TP?

A: The primary differences are product status and operating temperature range. The US1GE-TP is obsolete, while US1G-TP is active. The US1G-TP operates across -65°C to 175°C, compared to -50°C to 150°C for the US1GE-TP. All electrical specifications are identical.

Q: Are there packaging differences between these parts?

A: The US1GE-TP is supplied in SMAE packaging, while the US1G-TP is supplied in Tape & Reel (TR) format. Both use the DO-214AC (SMA) case style and are compatible with standard surface mount assembly equipment.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both US1GE-TP and US1G-TP are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which part should be selected for new designs?

A: The US1G-TP should be selected for new designs due to its active product status and extended operating temperature range, ensuring design longevity and supply availability.
