Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different ESR value?

A: Yes. The original part specifies 3 Ohm ESR. Substitute parts with ESR values between 1.8 Ohm and 4 Ohm are electrically compatible. Lower ESR values reduce power dissipation and heat generation. Higher ESR values increase power dissipation. Selection depends on circuit requirements for ripple current handling and thermal performance.

Q: What is the difference between molded and conformal coated tantalum capacitors?

A: Conformal coated variants (such as F951C226KQAAQ2) feature an additional protective coating over the capacitor body. This provides enhanced moisture and environmental protection. The F951C226KQAAQ2 has an MSL rating of 3 (168 Hours) compared to MSL 1 (Unlimited) for molded variants, indicating different moisture sensitivity handling requirements during assembly.

Q: Can I substitute a 10 V rated part for the original 6.3 V part?

A: Yes. The TAJA226K010A and TAJA226K010RNJ are direct upgrades with identical capacitance, tolerance, ESR, and package specifications. The elevated voltage rating provides additional design margin and is backward compatible with circuits designed for 6.3 V operation. This substitution is appropriate when higher voltage headroom is beneficial.

Q: What is the significance of the 1206 (3216 Metric) package designation?

A: The 1206 package is a surface mount component measuring 0.126" L x 0.063" W (3.20mm x 1.60mm). All substitute parts listed maintain this identical footprint and are directly compatible with existing PCB layouts. Height variations (0.047" to 0.071") are within acceptable clearance tolerances for standard assembly processes.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All active substitute parts listed carry RoHS3 compliance certification. The original TE Connectivity 1879062-7 is classified as obsolete and does not carry RoHS3 certification. Migration to any of the recommended active substitutes ensures compliance with current environmental and regulatory standards.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape (CT) & Digi-Reel® packaging is supplied in continuous tape format cut to specified lengths, suitable for manual assembly or small-volume production. Tape & Reel (TR) packaging is supplied on full reels for automated pick-and-place assembly. Both formats contain identical components; packaging selection depends on assembly process requirements and volume.

Q: Which substitute offers the lowest ESR?

A: The TPSA226K006R0500 offers the lowest ESR at 0.5 Ohm, compared to the original 3 Ohm specification. This part is suitable for applications requiring minimal impedance and reduced power dissipation. All other electrical and mechanical specifications remain identical to the original part.

Q: Can I use TAJS226K006RNJ if my PCB has limited vertical clearance?

A: Yes. The TAJS226K006RNJ has a maximum seated height of 0.047" (1.20mm), compared to 0.071" (1.80mm) for the original part. This reduced height makes it suitable for applications with restricted vertical clearance. All other specifications, including capacitance, voltage, ESR, and package footprint, remain identical.

Q: What inventory considerations should I evaluate?

A: Inventory availability varies significantly among substitutes. TAJA226K010RNJ offers the highest availability (505,400 pcs), followed by TAJA226K006RNJ (65,300 pcs). For immediate procurement needs, parts with higher inventory levels reduce lead time risk. The original TE Connectivity 1879062-7 has 722 pcs available but is obsolete and should not be selected for new designs.
