Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HS1BLH are grouped strictly based on the following key parameters: DC reverse voltage (Vr), average rectified current (Io), reverse recovery time (trr), forward voltage (Vf), reverse leakage current, capacitance, qualification standards (AEC-Q101), grade (automotive), mounting type, package type, and compliance status (RoHS, REACH). Only parts matching or exceeding these defined parameters are considered valid substitutes in this diode rectifier category.

Parameter Comparison

Engineering Selection Recommendations

HS1BLH is marked as "Not For New Designs." The listed substitute, HS1DLWH, is active and provides matching or exceeding electrical, mechanical, grade, and qualification parameters. Both diodes are AEC-Q101 qualified for automotive grade applications and maintain ROHS3 compliance and REACH unaffected status. Package type, mounting, and supply chain compliance are satisfied. Substitute selection is based on equivalency in product status, industry standard compliance, and certification.

Frequently Asked Questions (FAQ)

Q1: What are the main criteria for substituting HS1BLH with another part?
A1: Substitution is based on DC reverse voltage, average rectified current, reverse recovery time, forward voltage, reverse leakage current, capacitance, qualification (AEC-Q101), grade, mounting type, package, and compliance with RoHS and REACH standards.

Q2: Is HS1DLWH comparable in electrical performance to HS1BLH?
A2: HS1DLWH matches or exceeds the HS1BLH’s parameters in DC reverse voltage, current ratings, recovery time, and compliance, with comparable or better reverse leakage and capacitance.

Q3: Are there package differences to consider?
A3: HS1BLH uses SOD-123 (Sub SMA), while HS1DLWH uses SOD-123W. Both are surface mount packages in the same category, but dimensions may vary.

Q4: Are both diodes suitable for automotive applications?
A4: Both HS1BLH and HS1DLWH are automotive grade and AEC-Q101 qualified.

Q5: How does compliance impact substitute selection?
A5: Both parts are ROHS3 compliant and REACH unaffected, ensuring regulatory compliance is maintained when substituting.
