NCP103AMX210TCG Equivalent & Substitute Parts

Part Overview

The NCP103AMX210TCG is a linear voltage regulator IC from onsemi designed for positive fixed output applications. It delivers 150mA output current at a fixed 2.1V output voltage in a compact 4-UDFN (1.0x1.0) surface mount package. The device is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity. The NCP114AMX210TCG serves as the primary substitute, offering enhanced current capacity while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the NCP103AMX210TCG is determined by strict alignment of the following electrical and mechanical parameters:

• Output voltage: 2.1V fixed
• Input voltage maximum: 5.5V
• Package type: 4-UDFN Exposed Pad (1.0x1.0)
• Mounting type: Surface Mount
• Control features: Enable function
• Protection features: Over Current and Over Temperature protection
• Operating temperature range: -40°C ~ 85°C
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

The NCP114AMX210TCG qualifies as a direct substitute based on identical alignment across all these parameters. The primary distinction is the increased output current capacity (300mA versus 150mA), which represents an enhancement rather than a limitation for applications originally designed for the NCP103AMX210TCG.

Parameter Comparison

Engineering Selection Recommendations

The NCP114AMX210TCG is the appropriate substitute for the obsolete NCP103AMX210TCG. Both components maintain identical electrical specifications across output voltage, input voltage range, quiescent current, PSRR, control features, and protection mechanisms. Both are ROHS3 compliant and REACH unaffected, ensuring regulatory alignment.

The NCP114AMX210TCG carries active product status, ensuring continued availability and manufacturing support. The increased output current rating (300mA) provides design margin for applications originally specified at 150mA, with no adverse effects on existing circuit performance. Pinout and package dimensions remain identical, enabling direct PCB-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the NCP114AMX210TCG directly replace the NCP103AMX210TCG on existing PCBs?

A: Yes. Both components use the 4-UDFN Exposed Pad package with identical pinout and footprint dimensions (1.0x1.0). No PCB layout changes are required.

Q: What is the primary difference between these two parts?

A: The NCP114AMX210TCG provides 300mA output current capacity compared to the NCP103AMX210TCG's 150mA. All other electrical parameters, including output voltage, input voltage range, quiescent current, and protection features, are identical.

Q: Are there any compliance or certification differences?

A: No. Both components are ROHS3 compliant, REACH unaffected, and operate across the identical temperature range of -40°C to 85°C.

Q: Why is the NCP103AMX210TCG listed as obsolete?

A: The NCP103AMX210TCG has been discontinued by onsemi. The NCP114AMX210TCG represents the active product line continuation with enhanced specifications.

Q: Will the higher current rating of the NCP114AMX210TCG affect circuit behavior?

A: No. The increased current capacity does not alter voltage regulation, quiescent current draw, PSRR, or thermal characteristics. Applications drawing less than 150mA will operate identically to the original design.

Q: Are both parts available in the same packaging options?

A: Both use 4-UDFN Exposed Pad surface mount packaging. The NCP114AMX210TCG is available in Tape & Reel (TR) packaging for production volumes.
