Parameter Comparison

Engineering Selection Recommendations

The 25TQC33MYF is the direct substitute for the obsolete 25TQC33M based on the following engineering criteria:

Electrical Compatibility: Both parts share identical capacitance (33 µF) and voltage rating (25 V), ensuring functional equivalence in circuit applications.

Mechanical Compatibility: The substitute maintains the same 2917 (7343 Metric) package footprint, dimensions, and surface mount configuration, allowing direct PCB layout compatibility without redesign.

Product Lifecycle Status: The 25TQC33MYF is an active product with current manufacturing support, ensuring long-term availability and supply chain reliability. The original 25TQC33M is obsolete and subject to inventory depletion.

Compliance Certifications: The substitute part carries RoHS3 Compliant and REACH Unaffected certifications, meeting current regulatory requirements for electronic component procurement.

Performance Specifications: The substitute provides documented electrical characteristics including ESR (60 mOhm @ 100kHz), operating temperature range (-55°C ~ 105°C), and lifetime rating (2000 Hrs @ 105°C), enabling design verification and reliability analysis.

Frequently Asked Questions (FAQ)

Q: Can the 25TQC33MYF be used as a direct replacement for the 25TQC33M?

A: Yes. The 25TQC33MYF is the manufacturer-recommended substitute. Both parts have identical capacitance (33 µF), voltage rating (25 V), package footprint (2917 / 7343 Metric), and mounting type (Surface Mount). No circuit modifications or PCB layout changes are required.

Q: What is the difference between the 25TQC33M and 25TQC33MYF?

A: The primary difference is product status. The 25TQC33M is obsolete and no longer manufactured. The 25TQC33MYF is an active product from the POSCAP™ TQC series with current production and availability. Both parts are electrically and mechanically equivalent.

Q: Are there any compliance differences between these parts?

A: The 25TQC33MYF carries explicit RoHS3 Compliant and REACH Unaffected certifications. Compliance information for the obsolete 25TQC33M is not documented. For new designs or procurement requiring regulatory compliance documentation, the 25TQC33MYF is the appropriate choice.

Q: What packaging options are available for the substitute part?

A: The 25TQC33MYF is supplied in Tape & Reel (TR) packaging, which is standard for surface mount tantalum polymer capacitors in production environments.

Q: Are the electrical performance characteristics the same?

A: Both parts are molded tantalum polymer capacitors with 33 µF capacitance and 25 V rating. The 25TQC33MYF provides documented performance data: ESR of 60 mOhm @ 100kHz, operating temperature range of -55°C ~ 105°C, and lifetime rating of 2000 Hrs @ 105°C. The original 25TQC33M does not have published performance specifications.

Q: Can I use the 25TQC33MYF in existing inventory of boards designed for the 25TQC33M?

A: Yes. The identical package footprint (2917 / 7343 Metric), dimensions (0.287" L x 0.169" W, 0.079" max height), and surface mount configuration ensure mechanical and electrical compatibility with existing PCB designs without modification.
