Substitute Part Grouping Explanation

Substitution of the T86D336M016ESAS is determined by the following critical parameters:

• Capacitance Value: Must remain 33 µF to maintain circuit functionality
• Package / Case: Must be 2917 (7343 Metric) to ensure mechanical and electrical compatibility with PCB layouts
• Mounting Type: Must be Surface Mount to align with assembly processes
• Operating Temperature Range: Must support -55°C to 125°C minimum
• ESR: Must not exceed 700 mOhm to maintain electrical performance characteristics
• Type: Must be Molded Tantalum to preserve dielectric and reliability properties

The T83D336K025EZZS qualifies as a substitute because it maintains identical capacitance, package, mounting type, temperature range, and ESR specifications. The voltage rating upgrade from 16 V to 25 V and tolerance improvement from ±20% to ±10% represent enhanced electrical characteristics that do not compromise backward compatibility.

Engineering Selection Recommendations

The T83D336K025EZZS is the qualified substitute for the obsolete T86D336M016ESAS. Selection of this substitute is based on:

• Product Status Alignment: The substitute is active and currently available, addressing the obsolescence of the original part
• Electrical Compatibility: Identical capacitance, ESR, and operating temperature range ensure functional equivalence in circuit applications
• Mechanical Compatibility: Identical package dimensions and mounting type eliminate PCB redesign requirements
• Enhanced Specifications: The increased voltage rating (25 V vs. 16 V) and improved tolerance (±10% vs. ±20%) provide design margin without introducing incompatibility
• Compliance Consistency: Both parts share identical RoHS status, MSL rating, and REACH classification, maintaining regulatory alignment

Frequently Asked Questions (FAQ)

Q: Can the T83D336K025EZZS be used as a direct replacement for the T86D336M016ESAS?

A: Yes. The substitute maintains identical capacitance (33 µF), package (2917), mounting type (Surface Mount), ESR (700 mOhm), and operating temperature range (-55°C to 125°C). These parameters determine functional compatibility in circuit applications.

Q: What is the significance of the voltage rating increase from 16 V to 25 V?

A: The higher voltage rating of the substitute provides increased design margin and does not compromise backward compatibility. A 25 V rated capacitor operates safely in circuits designed for 16 V operation.

Q: Does the tolerance improvement from ±20% to ±10% affect compatibility?

A: No. The tighter tolerance of the substitute represents an enhancement that improves circuit performance without introducing incompatibility. Circuits designed for ±20% tolerance operate within specification with ±10% components.

Q: Are the physical dimensions identical between the two parts?

A: Yes. Both parts use the 2917 (7343 Metric) package with identical dimensions: 0.287" L x 0.169" W (7.30mm x 4.30mm) and maximum seated height of 0.122" (3.10mm). No PCB layout modifications are required.

Q: What is the availability status of the substitute part?

A: The T83D336K025EZZS is classified as Active and has 941 pieces in stock, ensuring supply continuity for new designs and production requirements.

Q: Are there any compliance or certification differences between the parts?

A: Both parts share identical RoHS status (non-compliant), MSL rating (1 - Unlimited), and REACH classification (REACH Unaffected). No compliance adjustments are necessary when substituting.
