CLLR1-10 TR Equivalent & Substitute Parts

Part Overview

The CLLR1-10 TR 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, necessitating identification of functionally equivalent alternatives for ongoing design requirements and procurement needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CLLR1-10 TR is determined by electrical parameter equivalence across the following criteria:

Electrical Equivalence Requirements:

• Voltage - DC Reverse (Vr) (Max): 1000 V minimum
• Current - Average Rectified (Io): 1 A minimum
• Voltage - Forward (Vf) (Max) @ If: 1.1 V or lower @ 1 A
• Speed: Standard Recovery >500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 10 µA or lower @ 1000 V

Mechanical Compatibility:

• Mounting Type: Surface Mount
• Package / Case: DO-213AB (MELF) or equivalent surface mount packages

The CMR1-10M TR13 meets all electrical parameters and operates as a functional equivalent, though with a different surface mount package configuration (SMA vs. MELF).

Parameter Comparison

Engineering Selection Recommendations

The CMR1-10M TR13 is an active product substitute for the obsolete CLLR1-10 TR. Both components share identical electrical ratings for reverse voltage, average rectified current, and forward voltage characteristics. The CMR1-10M TR13 demonstrates superior reverse leakage performance at 5 µA compared to 10 µA for the CLLR1-10 TR.

Primary consideration for substitution is package compatibility. The CLLR1-10 TR uses a MELF package (DO-213AB), while the CMR1-10M TR13 uses an SMA package (DO-214AC). PCB layout modifications are required to accommodate the different package footprint. The CMR1-10M TR13 operates within a junction temperature range of -65°C to 150°C, compared to -65°C to 175°C for the CLLR1-10 TR. Applications requiring operation above 150°C junction temperature require evaluation of alternative solutions.

The CMR1-10M TR13 is REACH unaffected and carries the same ECCN and HTSUS classifications as the original part.

Frequently Asked Questions (FAQ)

Q: Can the CMR1-10M TR13 directly replace the CLLR1-10 TR without PCB modifications?

A: No. The CLLR1-10 TR uses a MELF package (DO-213AB) while the CMR1-10M TR13 uses an SMA package (DO-214AC). These packages have different footprints and require PCB layout changes.

Q: Are the electrical characteristics identical between these two diodes?

A: The primary electrical ratings are equivalent: both are rated for 1000 V reverse voltage, 1 A average rectified current, and 1.1 V maximum forward voltage at 1 A. The CMR1-10M TR13 exhibits lower reverse leakage current (5 µA vs. 10 µA at 1000 V).

Q: What is the temperature operating range difference?

A: The CLLR1-10 TR operates from -65°C to 175°C junction temperature. The CMR1-10M TR13 operates from -65°C to 150°C. Applications requiring junction temperatures above 150°C cannot use the CMR1-10M TR13 as a substitute.

Q: Why is the CLLR1-10 TR listed as obsolete?

A: The CLLR1-10 TR is classified as obsolete by the manufacturer. The CMR1-10M TR13 is an active product offering equivalent electrical performance in a different package configuration.

Q: Are there any compliance or certification differences?

A: Both parts carry identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications. The CMR1-10M TR13 is REACH unaffected.
