CCLM3500 TR Equivalent & Substitute Parts

Part Overview

The CCLM3500 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 4.1mA and is housed in a SOD-80 (DO-213AC, MINI-MELF) surface mount package. The CCLM3500 TR is designated as obsolete, necessitating identification of functionally equivalent substitute components for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

The CMJ3500 TR PBFREE qualifies as a functional substitute for the CCLM3500 TR based on the following critical parameters:

Matching Electrical Specifications:

• Voltage - Anode - Cathode (Vak) Maximum: 100V (equivalent to input voltage rating)
• Regulator Current (Maximum): 4.1mA (identical output current specification)
• Mounting Type: Surface Mount (consistent with original)
• Manufacturer: Central Semiconductor Corp (same manufacturer)

Substitution Logic: Both components are current regulation devices from the same manufacturer with identical voltage and current ratings. The CMJ3500 TR PBFREE is classified as a discrete semiconductor product (diode current regulator) rather than an integrated circuit, but maintains electrical equivalence through matching voltage and current parameters. The substitute component is in active production status, providing design continuity for applications previously served by the obsolete CCLM3500 TR.

Engineering Selection Recommendations

The CMJ3500 TR PBFREE is the manufacturer-recommended substitute for the obsolete CCLM3500 TR. Selection of this substitute component is supported by the following factors:

Product Status Alignment: The substitute component is in active production status, ensuring long-term availability and supply chain continuity compared to the obsolete original part.

Electrical Equivalence: Both components maintain identical voltage (100V) and current (4.1mA) specifications, enabling direct functional replacement in current regulation applications.

Compliance and Certifications: The CMJ3500 TR PBFREE carries ROHS3 compliance and REACH unaffected status, meeting modern regulatory requirements. The ECCN classification (EAR99) indicates standard commercial availability.

Temperature Operating Range Consideration: The substitute component operates across -65°C to 150°C, which covers the majority of industrial and commercial temperature ranges. Applications requiring operation above 150°C (up to the original 200°C maximum) require thermal analysis to confirm suitability.

Package Transition: The substitute uses SOD-123F packaging instead of the original SOD-80. Physical board layout modifications are necessary to accommodate the different package footprint.

Frequently Asked Questions (FAQ)

Q: Can the CMJ3500 TR PBFREE directly replace the CCLM3500 TR without circuit modifications?

A: Electrical specifications are equivalent (100V, 4.1mA). However, the package change from SOD-80 to SOD-123F requires PCB layout modifications. Mechanical mounting and land pattern adjustments are necessary.

Q: What is the primary reason for substitution?

A: The CCLM3500 TR is obsolete and no longer manufactured. The CMJ3500 TR PBFREE is the active equivalent from the same manufacturer with identical electrical ratings.

Q: Are there temperature limitations with the substitute part?

A: The CMJ3500 TR PBFREE operates from -65°C to 150°C, compared to the original -65°C to 200°C range. Applications requiring sustained operation above 150°C require thermal evaluation.

Q: What packaging differences exist between these components?

A: The original CCLM3500 TR uses SOD-80 (DO-213AC, MINI-MELF) packaging. The substitute CMJ3500 TR PBFREE uses SOD-123F packaging. These are physically distinct packages requiring different PCB footprints.

Q: Is the substitute component RoHS compliant?

A: Yes, the CMJ3500 TR PBFREE is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the inventory status of the substitute part?

A: The CMJ3500 TR PBFREE has 6779 pieces in stock as new original inventory, providing immediate availability for production requirements.

Q: Are there any functional differences between the IC and discrete semiconductor implementations?

A: The CCLM3500 TR is an integrated circuit, while the CMJ3500 TR PBFREE is a discrete semiconductor (diode current regulator). Both provide equivalent current regulation function with identical electrical specifications.
