CCLM0500 TR Equivalent & Substitute Parts

Part Overview

The CCLM0500 TR is a current regulator integrated circuit manufactured by Central Semiconductor Corp, classified as a Power Management (PMIC) component. This device functions as a current regulator with a nominal output current of 630µA and maximum input voltage rating of 100V. The component is housed in a SOD-80 (DO-213AC, MINI-MELF) surface mount package.

The CCLM0500 TR carries an Obsolete product status. Locating equivalent or substitute components is necessary to support legacy system maintenance, repair operations, and continued product support where this regulator remains in active use. Substitute parts must maintain functional equivalence across critical electrical parameters including voltage rating, current regulation capability, and thermal operating range.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CCLM0500 TR is based on functional equivalence across the following critical parameters:

Voltage Rating: The substitute part must support a maximum anode-cathode voltage (Vak) of 100V or greater to maintain input voltage compatibility.

Current Regulation: The substitute part must provide a regulated current output of 630µA to ensure functional equivalence in current limiting applications.

Mounting Technology: The substitute part must utilize surface mount technology to maintain compatibility with existing PCB layouts and assembly processes.

Package Compatibility: While the original component uses SOD-80 packaging, substitute parts in alternative surface mount packages (SOD-123F) are acceptable provided all electrical parameters remain within specified tolerances and the physical footprint can be accommodated through PCB redesign or adapter solutions.

Operating Temperature: The substitute part must support the operating temperature range of -65°C to 150°C minimum to maintain thermal compatibility with the original design.

The CMJ0500 TR PBFREE meets these substitution criteria as a discrete semiconductor current regulator device.

Engineering Selection Recommendations

Product Status Consideration: The CMJ0500 TR PBFREE carries an Active product status, ensuring continued availability and manufacturing support. This addresses the primary limitation of the obsolete CCLM0500 TR.

Compliance and Certification: The CMJ0500 TR PBFREE is RoHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic components. The original CCLM0500 TR carries an Obsolete ECCN designation, whereas the substitute is classified as EAR99.

Electrical Equivalence: Both components maintain identical voltage and current specifications (100V maximum, 630µA regulation). The substitute part specifies a maximum power dissipation of 500mW, providing quantified thermal performance data absent from the original component specification.

Temperature Operating Range: The substitute part operates across -65°C to 150°C, which covers the lower portion of the original component's -65°C to 200°C range. Applications requiring operation above 150°C require thermal analysis to confirm the substitute's suitability.

Package Transition: Migration from SOD-80 to SOD-123F packaging requires PCB layout modification. The SOD-123F package is a standard surface mount form factor with established design guidelines and manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can the CMJ0500 TR PBFREE directly replace the CCLM0500 TR without PCB modification?

A: Direct replacement without PCB modification is not possible due to package differences. The original uses SOD-80 (MINI-MELF) packaging while the substitute uses SOD-123F. PCB footprint redesign is required. However, the electrical functionality and performance are equivalent.

Q: What is the significance of the "PBFREE" designation in the CMJ0500 TR PBFREE part number?

A: The PBFREE designation indicates the component is manufactured without lead (Pb), complying with RoHS3 environmental standards. This is a manufacturing process specification and does not affect electrical performance or substitution compatibility.

Q: Are there any temperature-related limitations when substituting the CMJ0500 TR PBFREE for the CCLM0500 TR?

A: The substitute part is rated for -65°C to 150°C operation, while the original supports -65°C to 200°C. Applications requiring sustained operation above 150°C should be evaluated for thermal performance. The 50°C reduction in maximum temperature rating may impact high-temperature applications.

Q: What does the "TR" designation in both part numbers indicate?

A: The "TR" designation indicates Tape & Reel packaging format, which is the standard supply method for surface mount components in automated assembly environments. This specification applies to both the original and substitute parts.

Q: Is the CMJ0500 TR PBFREE available in inventory?

A: Yes, the CMJ0500 TR PBFREE is listed as Active product status with 7,860 pieces in new original stock, compared to the obsolete CCLM0500 TR with 906 pieces remaining. The substitute part offers superior long-term availability.

Q: What is the voltage-limiting specification of the CMJ0500 TR PBFREE?

A: The CMJ0500 TR PBFREE specifies a maximum voltage-limiting (Vl) of 1.1V. This parameter defines the forward voltage drop across the current regulator element under regulated current conditions.

Q: How does the 500mW power rating of the CMJ0500 TR PBFREE compare to the original component?

A: The substitute part specifies 500mW maximum power dissipation. The original CCLM0500 TR does not provide a published power rating specification. The 500mW rating of the substitute provides quantified thermal design margin for circuit implementation.
