Key Parameters

Substitute Part Grouping Explanation

Substitute part grouping is based on electrical and mechanical parameters that strictly match or qualify for direct replacement within the defined category. The key parameters used for substitution are as follows:

• Voltage - DC Reverse (Vr) (Max)
• Current - Average Rectified (Io)
• Voltage - Forward (Vf) (Max) @ If
• Speed (Reverse Recovery Time, trr)
• Current - Reverse Leakage @ Vr
• Mounting Type
• Package / Case
• Operating Temperature - Junction

Only parts matching these criteria are considered valid substitutes for the CLLR1F-02 BK in rectifier diode applications.

Parameter Comparison

Engineering Selection Recommendations

Selection between CLLR1F-02 BK and CMR1F-02M BK should be based primarily on product status and compliance fields as supplied. The CLLR1F-02 BK is classified as obsolete, while the CMR1F-02M BK is active and listed with REACH Unaffected status. Both parts share the same ECCN and HTSUS codes. Product status and regulatory compliance should be confirmed as per project and sourcing requirements.

Frequently Asked Questions (FAQ)

Q1: What criteria must be matched to select a substitute for the CLLR1F-02 BK diode?
A1: Substitution is strictly based on Voltage - DC Reverse (Vr) (Max), Current - Average Rectified (Io), Voltage - Forward (Vf) (Max) @ If, Speed (Reverse Recovery Time, trr), Current - Reverse Leakage @ Vr, Mounting Type, Package / Case, and Operating Temperature - Junction.

Q2: Is package compatibility important when replacing the CLLR1F-02 BK?
A2: Yes. The main part uses a MELF (DO-213AB) package. Any substitute must be evaluated for mechanical fit and surface mount process compatibility based on the explicit package and mounting details provided.

Q3: How does product status affect component selection?
A3: The obsolete status of the CLLR1F-02 BK necessitates selecting an active component such as the CMR1F-02M BK to ensure availability and continued support.

Q4: Are there significant differences in electrical performance between the CLLR1F-02 BK and CMR1F-02M BK?
A4: All provided electrical parameters including voltage, current, forward voltage drop, reverse recovery time, and leakage current are matched between the two parts as per supplied data.

Q5: Does the operating temperature range impact substitution choice?
A5: The CLLR1F-02 BK supports a junction temperature range of -65°C to 175°C, while the CMR1F-02M BK supports -65°C to 150°C. Selection must align with application-specific temperature requirements as per supplied limits.
