ZMR250F02TC Equivalent & Substitute Parts

Part Overview

The ZMR250F02TC is a linear voltage regulator IC manufactured by Diodes Incorporated, designed for positive fixed output regulation at 2.5V with 50mA output current capacity. This Surface Mount device in SOT-23-3 packaging is classified as obsolete, making identification of functional equivalents essential for ongoing design support and production continuity. The part delivers regulated output with integrated over-current and over-temperature protection across an operating temperature range of -55°C to 125°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ZMR250F02TC is determined by strict equivalence across the following electrical and mechanical parameters:

• Fixed output voltage of 2.5V
• Output current capacity of 50mA
• Maximum input voltage of 22.5V
• Quiescent current of 40 µA
• PSRR specification of 75dB at 120Hz
• Operating temperature range of -55°C to 125°C
• SOT-23-3 package configuration
• Integrated over-current and over-temperature protection

The ZMR250FTA meets all these criteria as a parametric equivalent, with the primary distinction being packaging format (Tape & Reel versus individual component packaging) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The ZMR250FTA is the direct parametric equivalent for the obsolete ZMR250F02TC. Both parts are manufactured by Diodes Incorporated and share identical electrical specifications and SOT-23-3 package configuration. The ZMR250FTA maintains Active product status, ensuring continued availability and manufacturing support. Both parts carry ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements. The distinction between packaging formats (individual versus Tape & Reel) does not affect electrical performance or functional compatibility in circuit applications. Selection between these parts should be based on procurement requirements and supply chain considerations rather than technical performance criteria.

Frequently Asked Questions (FAQ)

Q: Can ZMR250FTA directly replace ZMR250F02TC in existing designs?

A: Yes. The ZMR250FTA is a parametric equivalent with identical electrical specifications, output voltage, current capacity, and SOT-23-3 package configuration. No circuit modifications are required.

Q: What is the difference between ZMR250F02TC and ZMR250FTA?

A: The primary differences are product status (Obsolete versus Active) and packaging format (individual component versus Tape & Reel). Electrical performance and package type are identical.

Q: Why is ZMR250F02TC listed as obsolete?

A: Obsolete status indicates the part is no longer in active production. The ZMR250FTA, as an active equivalent, is recommended for new designs and ongoing production requirements.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH Unaffected, and carry identical regulatory certifications.

Q: Does packaging format affect circuit performance?

A: No. Tape & Reel packaging is a supply format consideration only. Electrical performance and functional characteristics remain identical to individual component packaging.
