Substitute Part Grouping Explanation

Substitution for the ZXRE1004EFTC is determined by strict equivalence across the following critical parameters:

• Reference Type: Shunt
• Output Type: Fixed
• Voltage - Output: 1.22V
• Current - Output: 20 mA
• Tolerance: ±2%
• Temperature Coefficient: 75ppm/°C
• Noise - 10Hz to 10kHz: 60µVrms
• Current - Cathode: 8 µA
• Operating Temperature: -40°C ~ 85°C
• Package / Case: SOT-23-3

All identified substitute parts maintain identical electrical specifications and mechanical compatibility with the original component. Substitutes differ only in product status and packaging format (bulk vs. tape & reel).

Engineering Selection Recommendations

For applications currently using ZXRE1004EFTC, the ZXRE125EFTA is the primary recommended substitute. This part maintains full electrical and mechanical compatibility while offering active product status, ensuring long-term availability and manufacturing support. The ZXRE125EFTA is available in significantly higher inventory (22,780 pcs) compared to the original obsolete part.

The ZXRE1004EFTA serves as a secondary option, providing identical electrical specifications and packaging. However, this part carries Last Time Buy status, indicating limited future availability. Selection between ZXRE1004EFTA and ZXRE125EFTA should prioritize long-term supply chain stability.

Both substitute parts are ROHS3 compliant and REACH unaffected, maintaining regulatory compliance equivalent to the original component. Packaging format differences (tape & reel vs. bulk) do not affect electrical performance or mechanical fit in standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can ZXRE1004EFTA and ZXRE125EFTA be used interchangeably with ZXRE1004EFTC?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (1.22V fixed output, ±2% tolerance, 75ppm/°C temperature coefficient, 60µVrms noise, 20 mA output current) and identical SOT-23-3 packaging. Direct substitution is supported without circuit modification.

Q: What is the difference between ZXRE1004EFTA and ZXRE125EFTA?

A: The parts are electrically and mechanically identical. The primary difference is product lifecycle status: ZXRE1004EFTA is Last Time Buy, while ZXRE125EFTA is Active. For new designs and long-term production, ZXRE125EFTA is preferred due to ongoing availability.

Q: Does the tape & reel packaging format affect compatibility?

A: No. Tape & reel packaging is a distribution format used for automated assembly processes. The component itself maintains identical electrical performance and physical dimensions. Packaging format does not affect circuit functionality or PCB mounting.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. ZXRE1004EFTC, ZXRE1004EFTA, and ZXRE125EFTA are all ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: Why is ZXRE1004EFTC listed as obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. ZXRE125EFTA represents the current active equivalent from Diodes Incorporated for this voltage reference specification.
