Parameter Comparison

Engineering Selection Recommendations

Direct Manufacturer Substitutes (Preferred for New Designs):

M1MA142WKT1G (onsemi) is the primary recommended substitute. This part is manufactured by the original equipment manufacturer, carries Active product status, and is ROHS3 Compliant. It provides improved performance characteristics with a maximum junction temperature of 150°C and reduced reverse leakage current (100 nA @ 75 V). The reverse recovery time of 3 ns represents a performance enhancement over the original 4 ns specification. This part is available in high volume (20,100 pcs in stock) and is suitable for new design implementations.

Active Alternatives (Cross-Manufacturer Compatibility):

1SS301,LF (Toshiba Semiconductor and Storage) is an Active product with ROHS3 Compliance. This part maintains identical electrical specifications to the DCG010-TL-E, including 4 ns reverse recovery time and 500 nA reverse leakage current @ 80 V. It is available in Tape & Reel packaging with 3,900 pcs in stock.

1SS301SU,LF (Toshiba Semiconductor and Storage) is an Active product with RoHS Compliance. Electrical specifications are identical to 1SS301,LF. Inventory availability is 835 pcs.

DAN202FMFHT106 (Rohm Semiconductor) is an Active product with ROHS3 Compliance and AEC-Q101 automotive qualification. This part features improved reverse leakage characteristics (100 nA @ 70 V) and maximum junction temperature of 150°C. Automotive-grade qualification provides enhanced reliability for demanding applications. Inventory: 1,479 pcs.

DAN202FMT106 (Rohm Semiconductor) is an Active product with ROHS3 Compliance and AEC-Q101 automotive qualification. Electrical and thermal specifications are identical to DAN202FMFHT106. Inventory: 3,678 pcs.

Legacy Status Alternative (Existing Production Support Only):

DAN202UT106 (Rohm Semiconductor) carries "Not For New Designs" product status but remains available with ROHS3 Compliance. This part is suitable for sustaining production of existing designs or legacy system support only. Despite the legacy designation, it maintains full electrical compatibility and offers the highest inventory availability (497,627 pcs).

Selection Criteria by Application Context:

For new design implementations, select M1MA142WKT1G for onsemi ecosystem continuity or DAN202FMFHT106 / DAN202FMT106 for automotive-qualified applications requiring AEC-Q101 certification.

For existing production support of DCG010-TL-E designs, 1SS301,LF or 1SS301SU,LF provide direct cross-manufacturer compatibility with Active product status.

For legacy system maintenance where high inventory availability is critical, DAN202UT106 remains available despite "Not For New Designs" designation.

Frequently Asked Questions (FAQ)

Q: Can M1MA142WKT1G be used as a direct replacement for DCG010-TL-E in existing designs?

A: Yes. M1MA142WKT1G maintains all mandatory electrical parameters: 80 V reverse voltage, 100 mA average rectified current, 1.2 V forward voltage @ 100 mA, and identical SC-70, SOT-323 package configuration. The part is manufactured by onsemi, the original equipment manufacturer of DCG010-TL-E. Enhanced specifications (3 ns reverse recovery time, 150°C maximum junction temperature) provide performance improvement without compatibility issues.

Q: What is the difference between 1SS301,LF and 1SS301SU,LF?

A: Both parts are manufactured by Toshiba Semiconductor and Storage and maintain identical electrical specifications. The primary difference is packaging designation: 1SS301,LF is supplied in Tape & Reel (TR) format, while 1SS301SU,LF packaging is not specified in the provided data. Both are Active products with RoHS compliance. Selection between these parts depends on procurement and assembly process requirements.

Q: Are the Rohm Semiconductor DAN202 variants (DAN202FMFHT106, DAN202FMT106, DAN202UT106) interchangeable?

A: DAN202FMFHT106 and DAN202FMT106 are fully interchangeable. Both carry Active product status, ROHS3 Compliance, and AEC-Q101 automotive qualification. The difference is supplier device package designation (SOT-323 versus UMD3), which represents alternative packaging formats for the same SC-70, SOT-323 physical form factor. DAN202UT106 is electrically identical but carries "Not For New Designs" status and is suitable for legacy production support only.

Q: Why do some substitute parts show lower reverse leakage current (100 nA) compared to the original DCG010-TL-E (500 nA)?

A: Lower reverse leakage current represents improved device performance and is acceptable for substitution. The DCG010-TL-E specification of 500 nA @ 80 V establishes the maximum allowable leakage. Substitute parts with 100 nA @ 70 V or 100 nA @ 75 V demonstrate superior leakage characteristics and are fully compatible. This improvement does not create compatibility issues in circuit designs.

Q: Is AEC-Q101 automotive qualification required for substitution?

A: No. AEC-Q101 qualification is not required for substitution with the DCG010-TL-E. This qualification is an optional enhancement provided by DAN202FMFHT106 and DAN202FMT106. Selection of automotive-qualified parts depends on application requirements, not substitution compatibility. Non-automotive-qualified alternatives (M1MA142WKT1G, 1SS301,LF, 1SS301SU,LF, DAN202UT106) are fully compatible substitutes.

Q: Can DCG010-TL-E be replaced with a part rated for higher voltage or current?

A: No. Substitute parts must maintain the exact electrical ratings: 80 V reverse voltage and 100 mA average rectified current per diode. Parts with higher voltage or current ratings are not considered equivalent substitutes for this application. The DCG010-TL-E specifications define the functional requirements; substitutes must match these parameters precisely.

Q: What is the significance of "Not For New Designs" status for DAN202UT106?

A: "Not For New Designs" indicates that DAN202UT106 is maintained for existing production support and legacy system maintenance only. This designation does not affect electrical compatibility or performance. DAN202UT106 is suitable for sustaining production of existing designs that currently use DCG010-TL-E or for replacement in fielded systems. For new design implementations, select Active-status alternatives such as M1MA142WKT1G, 1SS301,LF, or DAN202FMFHT106.

Q: Are there packaging format differences between substitute parts?

A: Yes. Substitute parts are supplied in different packaging formats: M1MA142WKT1G is supplied in Tape & Reel (TR); 1SS301,LF is supplied in Tape & Reel (TR); 1SS301SU,LF packaging is not specified; DAN202FMFHT106 is supplied in Tape & Reel (TR); DAN202FMT106 is supplied in Tape & Reel (TR); DAN202UT106 is supplied in Cut Tape (CT) & Digi-Reel®. All parts maintain identical SC-70, SOT-323 physical form factor. Packaging format selection depends on assembly process requirements and procurement specifications, not electrical compatibility.

Q: What inventory considerations should guide substitute part selection?

A: Inventory availability varies significantly: M1MA142WKT1G (20,100 pcs), DAN202FMT106 (3,678 pcs), 1SS301,LF (3,900 pcs), DAN202UT106 (497,627 pcs), DAN202FMFHT106 (1,479 pcs), 1SS301SU,LF (835 pcs). For immediate production requirements, DAN202UT106 offers the highest availability. For new designs with longer lead times, M1MA142WKT1G or DAN202FMT106 provide adequate inventory with Active product status. Inventory levels should be verified at time of procurement, as availability is subject to change.
