Key Parameters

Substitute Part Grouping Explanation

Substitution of the L35L12VCB2 is determined by the following critical electrical and mechanical parameters:

• Voltage - Reverse Standoff: 12V (Max)
• Voltage - Breakdown (Min): 13.3V
• Voltage - Clamping (Max) @ Ipp: 35V
• Current - Peak Pulse: 10A (8/20µs)
• Power - Peak Pulse: 350W
• Capacitance @ Frequency: 0.6pF @ 1MHz
• Operating Temperature Range: -55°C ~ 125°C
• Package: SOD-323 surface mount

The DBLC12CI-7 meets all specified electrical parameters and maintains identical package and thermal specifications, qualifying it as a direct substitute. The primary distinction is channel configuration (1 channel vs. 2 channels in the original part) and expanded application support.

Parameter Comparison

Engineering Selection Recommendations

The DBLC12CI-7 is the qualified substitute for the L35L12VCB2. Selection is based on:

• Electrical parameter equivalence across all critical specifications
• Identical SOD-323 package and surface mount configuration
• Active product status ensuring ongoing availability and supply chain stability
• ROHS3 compliance and REACH unaffected status
• Moisture Sensitivity Level (MSL) 1 rating indicating unlimited shelf life

The transition from a 2-channel to 1-channel configuration does not affect substitution validity when circuit design accommodates single-channel operation. Verify circuit topology requirements prior to implementation.

Frequently Asked Questions (FAQ)

Q: Can the DBLC12CI-7 replace the L35L12VCB2 in all applications?

A: The DBLC12CI-7 meets all electrical and thermal specifications of the L35L12VCB2. The primary design consideration is the reduction from 2 channels to 1 channel. Confirm your circuit design requires only single-channel protection before substitution.

Q: Are the packages physically identical?

A: Both parts use the SOD-323 surface mount package (SC-76). PCB footprints and reflow profiles are compatible.

Q: What is the difference in application scope?

A: The L35L12VCB2 is specified for USB applications. The DBLC12CI-7 supports both Ethernet and USB applications, providing broader compatibility.

Q: Why is the L35L12VCB2 marked Last Time Buy?

A: Last Time Buy status indicates the manufacturer is discontinuing this product line. The DBLC12CI-7, with Active status, represents the ongoing product offering from Diodes Incorporated.

Q: Are there compliance differences between the two parts?

A: Both parts are ROHS3 compliant and REACH unaffected. The DBLC12CI-7 carries MSL 1 rating, indicating no moisture sensitivity limitations during storage.
