Key Parameters

Substitute Part Grouping Explanation

Substitution for the ZXRE125DFTC is determined by electrical and mechanical parameter equivalence across the following criteria:

• Fixed output voltage of 1.22V
• Output current rating of 20 mA
• Tolerance specification of ±1%
• Temperature coefficient of 75ppm/°C
• Noise performance of 60µVrms (10Hz to 10kHz)
• Cathode current of 8 µA
• Operating temperature range of -40°C to 85°C
• Surface Mount packaging in SOT-23-3 configuration
• ROHS3 compliance and MSL Level 1 rating

The identified substitute parts maintain identical electrical specifications and mechanical compatibility, differing only in product status and packaging format (Tape & Reel versus bulk).

Parameter Comparison

Engineering Selection Recommendations

For applications currently using ZXRE125DFTC, the ZXRE125DFTA is the primary substitute. This part maintains Active product status from Diodes Incorporated, ensuring long-term availability and manufacturing support. The ZXRE125DFTA is supplied in Tape & Reel format, standard for production environments, with 9080 pieces currently in stock.

The ZXRE1004DFTA serves as a secondary equivalent option, offering identical electrical performance and SOT-23-3 packaging. However, this part carries Last Time Buy status, indicating limited future availability. Selection between ZXRE1004DFTA and ZXRE125DFTA should prioritize the Active status part for new designs and long-term production requirements.

All three parts maintain ROHS3 compliance and MSL Level 1 rating, supporting environmental and moisture handling requirements across standard manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can ZXRE1004DFTA and ZXRE125DFTA be used interchangeably with ZXRE125DFTC?

A: Yes. All three parts share identical electrical specifications (1.22V fixed output, 20 mA current, ±1% tolerance, 75ppm/°C temperature coefficient) and mechanical compatibility in SOT-23-3 packaging. Substitution is electrically and mechanically valid.

Q: What is the difference between ZXRE1004DFTA and ZXRE125DFTA?

A: Both parts are parametric equivalents with identical electrical performance. The primary difference is product status: ZXRE125DFTA is Active, while ZXRE1004DFTA is Last Time Buy. For new designs, ZXRE125DFTA is recommended due to ongoing availability.

Q: Does packaging format affect substitution compatibility?

A: The ZXRE125DFTC is supplied in bulk format, while ZXRE1004DFTA and ZXRE125DFTA are supplied in Tape & Reel (TR) format. Both formats contain identical components in SOT-23-3 packaging. Tape & Reel format is standard for automated assembly processes and does not affect electrical or mechanical compatibility.

Q: Are there any compliance or certification differences?

A: No. All three parts maintain identical ROHS3 compliance, MSL Level 1 rating, REACH Unaffected status, and ECCN/HTSUS classifications.

Q: Why is ZXRE125DFTC marked as Obsolete?

A: Obsolete status indicates the part is no longer in active production. ZXRE125DFTA (Active status) and ZXRE1004DFTA (Last Time Buy status) provide equivalent functionality for design continuity and production support.
