Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DAP202FMFHT106 are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

Primary Matching Parameters:

• Diode Configuration: 1 Pair Common Anode
• Voltage - DC Reverse (Vr) (Max): 80 V
• Current - Average Rectified (Io) (per Diode): 100 mA
• Voltage - Forward (Vf) (Max) @ If: 1.2 V @ 100 mA
• Reverse Recovery Time (trr): 4 ns
• Speed Classification: Small Signal ≤ 200mA (Io), Any Speed
• Package / Case: SC-70, SOT-323
• Mounting Type: Surface Mount

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parts meeting all primary matching parameters and compliance requirements are classified as parametric equivalents and direct substitutes. Variations in secondary parameters such as reverse leakage current or maximum junction temperature do not preclude substitution when primary electrical and mechanical specifications align.

Parameter Comparison

Engineering Selection Recommendations

DAP202FMT106 (Rohm Semiconductor)

The DAP202FMT106 is a direct parametric equivalent to the DAP202FMFHT106. Both parts are manufactured by Rohm Semiconductor and share identical electrical specifications, package configuration, and automotive qualification status. The primary distinction is the packaging format designation (FMT versus FMFHT), which reflects different tape and reel configurations. This part maintains full compatibility with the main part number and is suitable for direct substitution in all applications. Higher inventory availability (6401 units) supports procurement continuity.

1SS300,LF (Toshiba Semiconductor and Storage)

The 1SS300,LF is a parametric equivalent manufactured by Toshiba Semiconductor and Storage. This part meets all primary electrical specifications including 80 V reverse voltage rating, 100 mA average rectified current, 1.2 V forward voltage, and 4 ns reverse recovery time. The device is housed in the same SC-70, SOT-323 package and maintains ROHS3 compliance and MSL 1 rating. Secondary parameter variations include higher reverse leakage current (500 nA @ 80 V versus 100 nA @ 70 V) and lower maximum junction temperature (125°C versus 150°C). These variations do not affect substitution eligibility for applications within the specified electrical operating range. The part is active in production with 5639 units in stock.

All three parts are active products with established supply availability and comply with automotive and environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can DAP202FMT106 be used as a direct replacement for DAP202FMFHT106?

A: Yes. The DAP202FMT106 is a direct parametric equivalent. Both parts are manufactured by Rohm Semiconductor and share identical electrical specifications, diode configuration, voltage ratings, current ratings, forward voltage characteristics, and package type. The difference in part number designation reflects packaging format variation only.

Q: Is the 1SS300,LF from Toshiba compatible with the DAP202FMFHT106?

A: Yes. The 1SS300,LF meets all primary electrical and mechanical specifications required for substitution. The part maintains the same 80 V reverse voltage rating, 100 mA current rating, 1.2 V forward voltage, 4 ns reverse recovery time, and SC-70, SOT-323 package configuration. The reverse leakage current specification is higher (500 nA @ 80 V) and the maximum junction temperature is lower (125°C), but these parameters do not prevent substitution for applications operating within the specified electrical range.

Q: Are all three parts suitable for automotive applications?

A: The DAP202FMFHT106 and DAP202FMT106 both carry automotive grade designation and AEC-Q101 qualification. The 1SS300,LF does not list automotive grade or AEC-Q101 qualification in the provided specifications. For applications requiring automotive qualification, the Rohm parts (DAP202FMFHT106 or DAP202FMT106) are the appropriate selections.

Q: What is the difference between SOT-323 and USM package designations?

A: SOT-323 and USM are supplier device package designations that may reflect different tape and reel configurations or supplier-specific packaging standards. Both designations correspond to the same physical SC-70, SOT-323 package case type. The parts are mechanically and electrically compatible for PCB assembly.

Q: Can these parts be used interchangeably in high-temperature applications?

A: The DAP202FMFHT106 and DAP202FMT106 are rated for 150°C maximum junction temperature. The 1SS300,LF is rated for 125°C maximum junction temperature. For applications approaching or exceeding 125°C junction temperature, the Rohm parts provide higher thermal margin.

Q: What is the significance of the RoHS3 compliance and MSL 1 rating?

A: ROHS3 compliance indicates the parts meet Restriction of Hazardous Substances Directive requirements and are suitable for use in regulated markets. MSL 1 (Unlimited) indicates the parts have unlimited shelf life and do not require special moisture control during storage or handling, simplifying inventory management and logistics.
