Substitute Part Grouping Explanation

Substitution of the CLL3595 BK is determined by electrical parameter equivalence across the following critical specifications:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 150 V
• Current - Average Rectified (Io): 150 mA
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 200 mA
• Reverse Recovery Time (trr): 3 µs
• Current - Reverse Leakage @ Vr: 1 nA @ 125 V
• Capacitance @ Vr, F: 8 pF @ 0V, 1MHz
• Operating Temperature - Junction: -65°C to 200°C
• Technology: Standard
• Speed Classification: Small Signal ≤ 200mA (Io), Any Speed

Mechanical Compatibility Consideration: Package form factor differences (SOD-80 versus SOD-123) require PCB layout and footprint verification during implementation.

Parameter Comparison

Engineering Selection Recommendations

The CMHD3595 BK qualifies as an electrical equivalent to the CLL3595 BK based on complete parameter alignment across all specified electrical characteristics. The substitute part offers the additional advantage of active product status, ensuring ongoing availability and supply chain continuity.

Compliance and Certification Status:

• CMHD3595 BK carries RoHS3 Compliance and REACH Unaffected designations, providing regulatory alignment for applications subject to these requirements.
• Both parts share identical ECCN (EAR99) and HTSUS (8541.10.0070) classifications.

Package Consideration: The primary distinction between the main part and substitute is the package form factor: CLL3595 BK uses SOD-80 (DO-213AC, MINI-MELF), while CMHD3595 BK uses SOD-123. This difference requires PCB footprint and layout verification to ensure mechanical compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: What makes CMHD3595 BK electrically equivalent to CLL3595 BK?

A: Both parts share identical electrical specifications across all critical parameters: 150V reverse voltage rating, 150mA average rectified current, 1V forward voltage at 200mA, 3µs reverse recovery time, 1nA reverse leakage current at 125V, and 8pF capacitance at 0V/1MHz. Operating temperature range, technology classification, and speed characteristics are also identical.

Q: Can I directly replace CLL3595 BK with CMHD3595 BK on my PCB?

A: Electrical substitution is valid; however, mechanical compatibility must be verified. The CLL3595 BK uses SOD-80 packaging while CMHD3595 BK uses SOD-123 packaging. PCB footprint, land pattern, and component placement must be evaluated to confirm physical fit.

Q: Why is CLL3595 BK listed as obsolete?

A: The CLL3595 BK is classified as obsolete by the manufacturer. CMHD3595 BK is the active equivalent part, ensuring continued availability for new designs and field replacements.

Q: Are there any compliance differences between these parts?

A: CMHD3595 BK includes RoHS3 Compliance and REACH Unaffected certifications. Both parts share identical ECCN and HTSUS classifications. Regulatory requirements for your application should be verified against these designations.

Q: What is the moisture sensitivity level for these diodes?

A: Both CLL3595 BK and CMHD3595 BK carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.
