CLLR1-10 TR13 Equivalent & Substitute Parts

Part Overview

The CLLR1-10 TR13 is a general-purpose rectifier diode manufactured by Central Semiconductor Corp, rated for 1000 V DC reverse voltage and 1 A average rectified current in a surface mount MELF package. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity. Substitute parts must maintain electrical performance across voltage, current, and thermal specifications while accommodating package and mounting differences.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CLLR1-10 TR13 is determined by equivalence in the following electrical parameters:

• Reverse Voltage Rating: 1000 V minimum
• Average Rectified Current: 1 A minimum
• Forward Voltage Drop: 1.1 V maximum at 1 A
• Recovery Speed: Standard recovery classification (>500 ns, >200 mA)
• Mounting Technology: Surface mount configuration
• Operating Temperature Range: Minimum -65°C to 175°C junction temperature capability

The CMR1-10M TR13 meets all electrical substitution criteria. Package differences (MELF versus SMA) and reverse leakage characteristics represent design trade-offs that do not preclude functional equivalence when circuit layout and thermal management accommodate the alternative package form factor.

Parameter Comparison

Engineering Selection Recommendations

The CMR1-10M TR13 is the primary substitute for the obsolete CLLR1-10 TR13. Both components are manufactured by Central Semiconductor Corp and share identical electrical ratings for reverse voltage, average rectified current, and forward voltage characteristics. The CMR1-10M TR13 carries active product status, ensuring continued availability and manufacturing support.

Key considerations for selection:

Electrical Compatibility: The CMR1-10M TR13 maintains all critical electrical parameters. The reverse leakage current is lower (5 µA versus 10 µA), representing improved performance characteristics.

Package Transition: The substitute uses SMA (DO-214AC) packaging instead of MELF (DO-213AB). This requires PCB layout modification and component placement adjustment. SMA packages are widely supported in modern surface mount assembly processes.

Temperature Range: The CMR1-10M TR13 operates to 150°C maximum junction temperature, compared to 175°C for the original part. Applications requiring operation above 150°C require thermal analysis to confirm compatibility.

Regulatory Compliance: Both parts carry identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications, maintaining export and tariff compliance.

Frequently Asked Questions (FAQ)

Q: Can the CMR1-10M TR13 directly replace the CLLR1-10 TR13 without circuit modification?

A: Electrical substitution is valid. The CMR1-10M TR13 meets all voltage, current, and thermal specifications. PCB layout modification is required due to package form factor change from MELF to SMA.

Q: What is the difference between MELF and SMA packages?

A: MELF (DO-213AB) and SMA (DO-214AC) are both surface mount packages with different physical dimensions and land patterns. SMA packages are larger and more commonly used in modern designs. Component placement and solder pad geometry differ between the two formats.

Q: Does the lower reverse leakage current of the CMR1-10M TR13 affect circuit performance?

A: Lower reverse leakage (5 µA versus 10 µA) represents improved performance. This change does not negatively impact circuit function and may reduce power dissipation in high-impedance applications.

Q: Is the reduced maximum junction temperature (150°C versus 175°C) a limitation?

A: The CMR1-10M TR13 operates to 150°C maximum junction temperature. Applications requiring sustained operation above 150°C require thermal analysis. Most standard rectifier applications operate well below this threshold.

Q: Are both parts RoHS and REACH compliant?

A: The CMR1-10M TR13 is listed as REACH Unaffected. Both parts carry identical ECCN and HTSUS classifications, confirming regulatory alignment for procurement and export purposes.

Q: What inventory status should influence procurement decisions?

A: The CLLR1-10 TR13 is obsolete with 1063 pieces in stock. The CMR1-10M TR13 is active with 1089 pieces available. Active product status ensures long-term supply continuity and manufacturing support.
