20TDC100MYF Equivalent & Substitute Parts

Part Overview

The 20TDC100MYF is a 100 µF molded tantalum polymer capacitor manufactured by Panasonic Electronic Components, rated for 20 V operation. This component belongs to the POSCAP™ TDC series and is designed for general-purpose surface mount applications in the 2917 (7343 Metric) package. The part is currently active in production with full RoHS3 compliance and REACH unaffected status. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and performance envelope.

Substitute Part Grouping Explanation

Substitution eligibility for the 20TDC100MYF is determined by strict equivalence across the following critical parameters:

  • Capacitance value: 100 µF (exact match required)
  • Voltage rating: 20 V (exact match required)
  • Tolerance: ±20% (exact match required)
  • ESR specification: 55 mOhm @ 100kHz (exact match required)
  • Package footprint: 2917 (7343 Metric) (exact match required)
  • Operating temperature range: -55°C to 125°C (exact match or better required)
  • Mounting type: Surface Mount (exact match required)
  • Compliance: RoHS3 and REACH status (equivalent or better required)

The KEMET T521V107M020ATE055 meets all substitution criteria as a direct equivalent within the same electrical and mechanical specifications.

Engineering Selection Recommendations

Both the 20TDC100MYF and T521V107M020ATE055 are active production components with full RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

  • Packaging format availability: The Panasonic part is supplied in Tape & Reel format, while the KEMET part is available in Cut Tape and Digi-Reel® formats.
  • Lifetime rating: The KEMET T521V107M020ATE055 provides 2000 hours at 125°C compared to 1000 hours for the Panasonic part, offering extended reliability in high-temperature applications.
  • Physical height: The KEMET part has a maximum seated height of 0.079" (2.00mm) versus 0.118" (3.00mm) for the Panasonic part, which may be relevant for space-constrained designs.
  • Inventory and lead time: Component availability should be verified with your supplier based on current stock levels and project timelines.

Frequently Asked Questions (FAQ)

Q: Can the T521V107M020ATE055 be used as a direct replacement for the 20TDC100MYF?

A: Yes. Both parts share identical electrical specifications (100 µF, 20 V, ±20% tolerance, 55 mOhm ESR) and the same 2917 (7343 Metric) package footprint. They are mechanically and electrically interchangeable for PCB assembly.

Q: What is the difference in height between these two parts?

A: The Panasonic 20TDC100MYF has a maximum seated height of 0.118" (3.00mm), while the KEMET T521V107M020ATE055 is 0.079" (2.00mm). The KEMET part is lower profile and may be preferred in applications with height constraints.

Q: Does the difference in lifetime rating affect substitution eligibility?

A: No. The KEMET part's extended lifetime rating of 2000 hours at 125°C versus 1000 hours for the Panasonic part represents an improvement in reliability and does not prevent substitution. Both parts meet the minimum operating requirements.

Q: Are there packaging format differences between these parts?

A: Yes. The Panasonic part is supplied in Tape & Reel (TR) format, while the KEMET part is available in Cut Tape (CT) and Digi-Reel® formats. Verify packaging compatibility with your assembly process and supplier availability.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 20TDC100MYF and T521V107M020ATE055 are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
