Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CLL4150 BK PBFREE is determined by the following critical parameters:

Primary Compatibility Criteria:

• Voltage - DC Reverse (Vr) (Max): Must equal or exceed 50 V
• Package / Case: Must be DO-213AC, MINI-MELF, or SOD-80
• Mounting Type: Must be Surface Mount
• Current - Average Rectified (Io): Must equal or exceed 300 mA
• Speed Classification: Must be Fast Recovery ≤ 500ns, > 200mA (Io)
• Reverse Recovery Time (trr): Must equal or be less than 4 ns
• RoHS Status: Must be ROHS3 Compliant

Identified Substitute Parts:

LL4150GS08 (Vishay General Semiconductor - Diodes Division): Meets all primary compatibility criteria with identical voltage, current, speed, and recovery time specifications. Packaging format differs (Cut Tape & Digi-Reel® versus Bulk), and capacitance is lower (2.5 pF versus 4 pF).

LL4150GS18 (Vishay General Semiconductor - Diodes Division): Meets all primary compatibility criteria with identical voltage, speed, and recovery time specifications. Current rating is doubled (600 mA versus 300 mA), providing higher current capacity. Packaging format differs (Tape & Reel versus Bulk), and capacitance is lower (2.5 pF versus 4 pF).

Parameter Comparison

Engineering Selection Recommendations

LL4150GS08 Selection Criteria: LL4150GS08 is electrically and mechanically equivalent to CLL4150 BK PBFREE across all critical parameters. Both components maintain identical voltage rating (50 V), current rating (300 mA), forward voltage drop (1 V @ 200 mA), recovery time (4 ns), and reverse leakage current (100 nA @ 50 V). Both are Active status products with ROHS3 compliance and MSL 1 rating. Selection of LL4150GS08 is appropriate when Cut Tape & Digi-Reel® packaging format is acceptable for manufacturing or assembly processes. The lower capacitance value (2.5 pF versus 4 pF) does not affect substitution eligibility within the specified parameter set.

LL4150GS18 Selection Criteria: LL4150GS18 is electrically and mechanically compatible with CLL4150 BK PBFREE with one significant difference: the current rating is doubled to 600 mA. This higher current capacity allows LL4150GS18 to function in applications requiring up to 600 mA average rectified current while maintaining all other electrical characteristics (50 V reverse voltage, 1 V forward voltage drop, 4 ns recovery time, 100 nA reverse leakage). Both are Active status products with ROHS3 compliance and MSL 1 rating. Selection of LL4150GS18 is appropriate when Tape & Reel packaging format is required or when circuit design permits use of a higher current-rated component. The lower capacitance value (2.5 pF versus 4 pF) does not affect substitution eligibility.

Compliance and Regulatory Status: All three components (CLL4150 BK PBFREE, LL4150GS08, LL4150GS18) maintain ROHS3 compliance, REACH Unaffected status, and EAR99 ECCN classification. All components are classified as Active products with unlimited moisture sensitivity (MSL 1).

Frequently Asked Questions (FAQ)

Q: Can LL4150GS08 be used as a direct replacement for CLL4150 BK PBFREE?

A: Yes. LL4150GS08 meets all electrical and mechanical compatibility requirements. Both components share identical voltage rating (50 V), current rating (300 mA), forward voltage drop (1 V @ 200 mA), reverse recovery time (4 ns), and reverse leakage current (100 nA @ 50 V). Both use the SOD-80 surface mount package. The primary difference is packaging format: CLL4150 BK PBFREE is supplied in Bulk, while LL4150GS08 is supplied in Cut Tape & Digi-Reel® format.

Q: What is the difference between LL4150GS08 and LL4150GS18?

A: The primary difference is current rating. LL4150GS08 is rated for 300 mA average rectified current, matching the CLL4150 BK PBFREE specification. LL4150GS18 is rated for 600 mA average rectified current, providing double the current capacity. All other electrical parameters (voltage, forward drop, recovery time, leakage current) are identical. LL4150GS18 is supplied in Tape & Reel packaging, while LL4150GS08 is supplied in Cut Tape & Digi-Reel® format.

Q: Can LL4150GS18 be used in place of CLL4150 BK PBFREE?

A: Yes. LL4150GS18 meets all electrical and mechanical compatibility requirements with the additional benefit of higher current capacity (600 mA versus 300 mA). This higher rating does not create incompatibility; it provides additional design margin. Both components share identical voltage rating (50 V), forward voltage drop (1 V @ 200 mA), reverse recovery time (4 ns), and reverse leakage current (100 nA @ 50 V). Both use the SOD-80 surface mount package.

Q: Are there temperature range differences between these components?

A: Yes. CLL4150 BK PBFREE operates across -65°C to 200°C junction temperature range. Both LL4150GS08 and LL4150GS18 operate across -55°C to 175°C junction temperature range. The CLL4150 BK PBFREE provides wider temperature coverage at both low and high ends. For applications requiring operation below -55°C or above 175°C, CLL4150 BK PBFREE is the appropriate selection.

Q: Do packaging format differences affect electrical performance?

A: No. Packaging format (Bulk, Cut Tape & Digi-Reel®, or Tape & Reel) does not affect electrical performance or component specifications. Format selection is determined by manufacturing process requirements, assembly equipment compatibility, and supply chain logistics. All three components deliver identical electrical characteristics within their respective current ratings.

Q: What is the significance of the capacitance difference (4 pF versus 2.5 pF)?

A: Capacitance values are provided for reference in high-frequency applications. The CLL4150 BK PBFREE specifies 4 pF at 0 V and 1 MHz, while both LL4150GS08 and LL4150GS18 specify 2.5 pF at the same conditions. This difference does not affect substitution eligibility within the specified parameter set and does not impact standard rectification applications. High-frequency circuit designers should verify capacitance requirements against specific application needs.

Q: Are all three components RoHS3 compliant?

A: Yes. CLL4150 BK PBFREE, LL4150GS08, and LL4150GS18 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status. All three components are classified as Active products suitable for current production use.
