Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMLD6263S TR TIN/LEAD is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Diode Configuration: 2 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 70 V
• Current - Average Rectified (Io) (per Diode): 15 mA (DC)
• Voltage - Forward (Vf) (Max) @ If: 410 mV @ 1 mA
• Reverse Recovery Time (trr): 5 ns
• Current - Reverse Leakage @ Vr: 200 nA @ 50 V
• Operating Temperature - Junction: -65°C ~ 150°C

Mechanical Parameters (Must Match Exactly):

• Package / Case: SOT-563, SOT-666
• Mounting Type: Surface Mount

Allowed Variations:

• Packaging format (Tape & Reel vs. other formats)
• RoHS compliance status
• Manufacturer finish specifications (TIN/LEAD vs. PBFREE)

The CMLD6263C TR PBFREE qualifies as a parametric equivalent because it maintains identical electrical and mechanical specifications while differing only in RoHS compliance classification and lead finish.

Parameter Comparison

Engineering Selection Recommendations

CMLD6263S TR TIN/LEAD is suitable for applications where RoHS non-compliance is acceptable and tin/lead finish is specified. Product status is Active with moderate inventory availability (831 pieces).

CMLD6263C TR PBFREE is the direct parametric equivalent for applications requiring ROHS3 compliance. This variant maintains identical electrical performance and mechanical compatibility while meeting lead-free and RoHS3 regulatory requirements. Product status is Active with higher inventory availability (14,741 pieces).

Selection between these two parts should be based solely on:

1. RoHS compliance requirements of the end application
2. Lead finish specifications mandated by assembly or environmental standards
3. Inventory availability and supply chain considerations

Both parts are manufactured by Central Semiconductor Corp and share the same base product number (CMLD6263), confirming parametric equivalence.

Frequently Asked Questions (FAQ)

Q: Can CMLD6263C TR PBFREE be used as a direct replacement for CMLD6263S TR TIN/LEAD?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications. The difference is limited to RoHS compliance status and lead finish. Direct substitution is valid from an electrical and mechanical standpoint.

Q: What does the "TR" designation indicate?

A: TR indicates Tape & Reel packaging format, which is the standard format for surface mount components in automated assembly processes.

Q: What is the difference between TIN/LEAD and PBFREE finishes?

A: TIN/LEAD refers to traditional lead-containing solder finish, while PBFREE indicates lead-free finish. The CMLD6263C TR PBFREE is compliant with ROHS3 regulations that restrict hazardous substances including lead.

Q: Are there any thermal or electrical performance differences between these two parts?

A: No. Both parts maintain identical operating temperature range (-65°C ~ 150°C), forward voltage (410 mV @ 1 mA), reverse recovery time (5 ns), and all other electrical parameters.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications subject to RoHS3 compliance mandates, CMLD6263C TR PBFREE is the appropriate choice. For legacy systems or applications without RoHS requirements, either part is acceptable based on availability.

Q: Is the SOT-563 package compatible with SOT-666?

A: Both parts are specified for SOT-563 and SOT-666 packages. Verify the specific package requirement for your application, as these are distinct package types with different pin configurations and footprints.
