Substitute Part Grouping Explanation

Substitution of the ZMR250FTC is determined by strict equivalence across the following critical parameters:

  • Output voltage specification: 2.5V fixed output
  • Output current capacity: 50mA minimum
  • Maximum input voltage rating: 22.5V or greater
  • Package type: SOT-23-3 surface mount configuration
  • Protection features: Over current and over temperature protection
  • Operating temperature range: -55°C to 125°C or wider
  • Quiescent current: 40 µA
  • PSRR performance: 75dB at 120Hz

The ZMR250FTA qualifies as a parametric equivalent substitute based on identical electrical specifications and package configuration. The primary distinction between these parts is packaging format (bulk versus tape & reel) and product status (obsolete versus active).

Engineering Selection Recommendations

The ZMR250FTA is the direct substitute for the ZMR250FTC. Both parts share identical electrical and mechanical specifications, with the ZMR250FTA maintaining Active product status and higher inventory availability (35,400 units versus 947 units).

Selection between these parts should be based on:

  • Supply chain requirements: The ZMR250FTA offers superior long-term availability due to Active product status
  • Packaging format: The ZMR250FTC is supplied in bulk packaging, while the ZMR250FTA is supplied in tape & reel format
  • Compliance requirements: Both parts meet ROHS3 compliance and REACH unaffected status, suitable for regulated applications

No additional technical evaluation is required for substitution, as electrical performance and thermal characteristics are identical across both part numbers.

Frequently Asked Questions (FAQ)

Q: Can the ZMR250FTA directly replace the ZMR250FTC in existing designs?

A: Yes. The ZMR250FTA is a direct parametric equivalent. All electrical specifications, output voltage, current ratings, protection features, and operating temperature ranges are identical. The SOT-23-3 package footprint is the same, requiring no PCB layout modifications.

Q: What is the difference between ZMR250FTC and ZMR250FTA?

A: The primary differences are product status and packaging format. The ZMR250FTC is Obsolete and supplied in bulk packaging. The ZMR250FTA is Active and supplied in tape & reel format. Electrical and mechanical specifications are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical RoHS3 compliance status and REACH unaffected designation. Both are suitable for applications requiring regulatory compliance in these areas.

Q: What is the significance of the packaging format difference?

A: Tape & reel packaging (ZMR250FTA) is standard for automated assembly processes and high-volume production. Bulk packaging (ZMR250FTC) is typically used for manual assembly or lower-volume applications. The electrical device itself is identical.

Q: Should I use the ZMR250FTA for new designs?

A: Yes. The ZMR250FTA is recommended for new designs due to its Active product status and higher inventory availability, ensuring long-term supply chain support.
