GS1GFL-TP Equivalent & Substitute Parts

Part Overview

The GS1GFL-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 400 V DC reverse voltage and 1 A average rectified current in a surface mount DO-221AC (SMA Flat Leads) package. This component is classified as "Not For New Designs," indicating it has reached end-of-life status. Identifying equivalent and substitute parts is necessary to support existing applications, legacy system maintenance, and design transitions to active product lines that meet current manufacturing and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the GS1GFL-TP is determined by strict alignment of the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Voltage - DC Reverse (Vr) (Max): Must equal or exceed 400 V
• Current - Average Rectified (Io): Must equal or exceed 1 A
• Package / Case: Must be DO-221AC with SMA Flat Leads
• Mounting Type: Must be Surface Mount
• Speed Classification: Must be Standard Recovery >500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: Must not exceed 10 µA @ 400 V
• RoHS Status: Must be ROHS3 Compliant

The SE30AFGHM3/6B from Vishay General Semiconductor - Diodes Division qualifies as a substitute part. It meets or exceeds all critical electrical parameters (400 V reverse voltage, 1.4 A average rectified current), maintains identical package and mounting specifications, and complies with the same RoHS3 standard. The substitute part demonstrates enhanced performance characteristics including higher current rating and extended operating temperature range, while maintaining backward compatibility with the original part's electrical classification and physical footprint.

Parameter Comparison

Engineering Selection Recommendations

The SE30AFGHM3/6B is a qualified substitute for the GS1GFL-TP based on the following engineering criteria:

Electrical Compatibility: The substitute part maintains identical reverse voltage rating (400 V) and exceeds the average rectified current requirement (1.4 A versus 1 A). Reverse leakage current and recovery speed specifications are identical, ensuring functional equivalence in rectification performance.

Physical Compatibility: Both parts use the DO-221AC package with SMA Flat Leads in surface mount configuration, enabling direct board-level substitution without layout modifications.

Compliance Status: The SE30AFGHM3/6B is ROHS3 compliant, matching the original part's environmental compliance. The substitute additionally carries AEC-Q101 automotive qualification, providing enhanced reliability documentation for applications requiring automotive-grade components.

Product Status Advantage: The substitute part holds Active product status, ensuring long-term availability and manufacturing support, whereas the GS1GFL-TP is designated "Not For New Designs." This transition supports supply chain continuity and future design sustainability.

Thermal Performance: The substitute part extends the operating temperature range to 175 °C (versus 150 °C), providing additional thermal margin for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can the SE30AFGHM3/6B directly replace the GS1GFL-TP on existing PCBs?

A: Yes. Both parts use identical DO-221AC package geometry with SMA Flat Leads and surface mount configuration. No PCB layout or footprint modifications are required for direct substitution.

Q: What is the significance of the higher current rating (1.4 A) on the substitute part?

A: The substitute part's 1.4 A average rectified current rating exceeds the original 1 A requirement. This provides additional current capacity margin and does not create compatibility issues. The part will function correctly in applications designed for 1 A operation.

Q: Are there differences in forward voltage characteristics?

A: The substitute part specifies forward voltage at a higher current level (1.1 V @ 3 A versus 1 V @ 1 A). At the original part's rated current of 1 A, forward voltage characteristics are comparable and functionally equivalent for circuit design purposes.

Q: Why does the substitute part have AEC-Q101 qualification?

A: AEC-Q101 is an automotive industry qualification standard. The SE30AFGHM3/6B meets this standard, indicating it has undergone additional reliability testing and quality assurance protocols. This qualification is beneficial for applications requiring automotive-grade components but does not restrict use in non-automotive applications.

Q: Is the slightly higher capacitance (19 pF versus 15 pF) a concern?

A: The capacitance difference is minor (4 pF) and occurs at identical measurement conditions (4 V, 1 MHz). This small variance does not affect circuit performance in standard rectification applications and is within normal manufacturing tolerance ranges for diode components.

Q: What is the advantage of the extended temperature range (-55 to 175 °C)?

A: The substitute part's extended upper temperature limit (175 °C versus 150 °C) provides additional thermal margin. This is beneficial for applications operating in high-temperature environments or with limited thermal management, though it does not restrict use in applications within the original part's temperature range.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the GS1GFL-TP and SE30AFGHM3/6B are ROHS3 compliant, meeting current environmental and hazardous substance restrictions for electronic components.

Q: What is the practical difference between "Not For New Designs" and "Active" product status?

A: "Not For New Designs" indicates the GS1GFL-TP has reached end-of-life and is no longer recommended for new circuit designs. "Active" status for the SE30AFGHM3/6B confirms ongoing manufacturing, long-term availability, and manufacturer support. For new designs or long-term supply chain planning, the active substitute part is the appropriate selection.
