AVGA476M50X16T-F Equivalent & Substitute Parts

Part Overview

The AVGA476M50X16T-F is a 47 µF, 50 V aluminum electrolytic capacitor in surface mount radial can package manufactured by Cornell Dubilier Electronics (CDE). This component is rated for 2000 hours at 105°C with ±20% capacitance tolerance and operates across -40°C to 105°C. The part is classified as obsolete, necessitating identification of active equivalent and substitute components for ongoing production and maintenance applications. Substitute parts must maintain the core electrical specifications: 47 µF capacitance, 50 V rated voltage, ±20% tolerance, 2000-hour minimum lifetime at 105°C, and compatible surface mount radial can package dimensions.

Substitute Part Grouping Explanation

Substitute parts are classified into three categories based on substitution criteria:

Direct Substitutes (Active Status): Parts meeting all core electrical parameters (47 µF, 50 V, ±20% tolerance, 2000 Hrs @ 105°C minimum) with identical or compatible package dimensions (0.248" diameter, maximum height 0.315" to 0.323", surface mount land size 0.260" L x 0.260" W or 0.260" L x 0.307" W). These parts are currently in active production status and are suitable for direct replacement in new designs and existing applications.

Upgrade Substitutes (Enhanced Performance): Parts exceeding minimum specifications in lifetime rating (3000 Hrs @ 105°C or 2000 Hrs @ 125°C) or ESR characteristics while maintaining all core electrical parameters and package compatibility. These components provide improved reliability margins.

Parametric Equivalents (General Purpose): Parts matching all electrical specifications and package dimensions but with different application ratings or certifications. These are suitable for general-purpose applications where automotive or specialized ratings are not required.

Key parameters determining substitution eligibility:

Capacitance: 47 µF (exact match required)
Voltage Rating: 50 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime: Minimum 2000 Hrs @ 105°C
Package: Radial, Can - SMD with compatible dimensions
Polarization: Polar (exact match required)
Mounting: Surface Mount (exact match required)

Frequently Asked Questions (FAQ)

Q: Can AFK476M50X16T-F directly replace AVGA476M50X16T-F in existing PCB layouts?

A: Yes. Both parts share identical capacitance (47 µF), voltage rating (50 V), tolerance (±20%), and core package dimensions (0.248" diameter, 6.30mm). The maximum seated height differs by 0.02" (0.20mm), which is within typical PCB clearance tolerances. AFK476M50X16T-F operates across a wider temperature range (-55°C to 105°C) and is in active production status.

Q: What is the difference between Cut Tape & Digi-Reel and Tape & Reel packaging?

A: Both packaging formats are suitable for automated assembly. Cut Tape & Digi-Reel (used by EDH476M050S9HAA, UCD1H470MCL1GS, UUD1H470MCL1GS) provides flexibility for lower-volume production runs. Tape & Reel (used by AFK476M50X16T-F, 50TZV47M6.3X8, EEE-FK1H470XP, EEE-HBH470YAP, EMLA500ARA470MF80G) is optimized for high-volume automated assembly. Selection depends on production volume and equipment compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance status, matching the original AVGA476M50X16T-F specification.

Q: Which substitute part offers the best reliability for long-term operation?

A: EMLA500ARA470MF80G provides the highest reliability margin with 3000-hour lifetime at 105°C, compared to the 2000-hour standard specification. This part maintains all core electrical parameters and package compatibility while offering 50% extended operational life rating.

Q: Can I use UCZ1H470MCS6GS as a substitute?

A: UCZ1H470MCS6GS meets all electrical specifications and package requirements. However, this part carries product status "Not For New Designs." It is suitable only for maintenance and repair of existing equipment where this specific part is already in service. For new production designs, select from parts with active production status.

Q: What is the significance of AEC-Q200 qualification?

A: AEC-Q200 is an automotive industry qualification standard. Parts carrying this rating (AFK476M50X16T-F, 50TZV47M6.3X8, EDH476M050S9HAA, EEE-FK1H470XP, EEE-HBH470YAP, UCD1H470MCL1GS, UUD1H470MCL1GS) meet stringent automotive reliability and performance requirements. These parts are suitable for automotive applications and general industrial use.

Q: How do I select between multiple equivalent parts?

A: Selection criteria are: (1) Product Status—prioritize Active status parts for new designs; (2) Packaging—choose based on assembly equipment compatibility; (3) Inventory—verify availability for production schedules; (4) Application Requirements—select AEC-Q200 qualified parts for automotive applications; (5) Reliability Margin—consider EMLA500ARA470MF80G for extended lifetime requirements.

Q: Is the surface mount land size difference between 0.260" x 0.260" and 0.260" x 0.307" significant?

A: The difference is minor. AFK476M50X16T-F uses 0.260" L x 0.307" W land size versus the standard 0.260" L x 0.260" W. This 0.047" (1.20mm) width difference accommodates manufacturing tolerances and does not affect PCB layout compatibility for most applications. Verify with your PCB design guidelines if space constraints exist.
