Key Parameters

Substitute Part Grouping Explanation

Substitute parts are selected strictly based on matching or exceeding the electrical and mechanical key parameters supplied. Parameters used for grouping include: Voltage - DC Reverse (Vr) (Max), Current - Average Rectified (Io), Voltage - Forward (Vf) (Max) @ If, Speed (Fast Recovery), Reverse Recovery Time (trr), Current - Reverse Leakage @ Vr, Mounting Type, Package / Case, Supplier Device Package, Operating Temperature - Junction, RoHS Status, and Product Status.

Parameter Comparison

Engineering Selection Recommendations

Selection based on product status should use only active, in-stock components. Compliance status is an important criterion; 1N6622US is RoHS non-compliant, while STTH2L06A is ROHS3 compliant. Both components are REACH unaffected and have a Moisture Sensitivity Level (MSL) of 1 (Unlimited). For applications requiring RoHS compliance, STTH2L06A is compliant.

Frequently Asked Questions (FAQ)

Q1: What are the most critical parameters when substituting the 1N6622US?
A1: Key parameters are: Voltage - DC Reverse (Vr) (Max), Current - Average Rectified (Io), Voltage - Forward (Vf) (Max) @ If, Speed (Fast Recovery), Reverse Recovery Time (trr), Current - Reverse Leakage @ Vr, mounting type, and package.

Q2: Are there differences in packaging between the 1N6622US and STTH2L06A?
A2: Yes. The 1N6622US uses the A-MELF (SQ-MELF, A) surface mount package, whereas the STTH2L06A uses the SMA (DO-214AC) surface mount package.

Q3: How do RoHS and REACH statuses affect substitute selection?
A3: If regulatory compliance is required (e.g., RoHS), only components explicitly listed as compliant should be selected. Both devices are REACH unaffected, but only STTH2L06A is ROHS3 compliant.

Q4: Does substituting with STTH2L06A affect electrical compatibility?
A4: Refer strictly to Voltage - DC Reverse (Vr) (Max), Current - Average Rectified (Io), and other parameters in the comparison table to ensure alignment with system requirements.

Q5: Is the Moisture Sensitivity Level (MSL) compatible between the two devices?
A5: Yes, both have MSL = 1 (Unlimited) as indicated in the provided data.
