TACR335M010R Equivalent & Substitute Parts

Part Overview

The TACR335M010R is a 3.3 µF molded tantalum capacitor manufactured by KYOCERA AVX, rated for 10 V operation in a 0805 (2012 Metric) surface mount package. This component is classified as Active and suitable for general-purpose applications requiring stable capacitance in compact form factors.

Substitute parts become necessary when the original component reaches end-of-life status, inventory constraints occur, or design requirements shift toward improved electrical characteristics such as higher voltage ratings or tighter tolerance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TACR335M010R is determined by the following criteria:

Primary Substitution Parameters:

• Capacitance value: 3.3 µF (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (minimum requirement)

Secondary Substitution Parameters (allowable variation):

• Voltage Rating: Equal to or greater than 10 V
• Tolerance: ±20% or tighter
• ESR: Equal to or lower than 5 Ohm
• Type: Molded Tantalum (same technology)

Two substitute parts meet these criteria:

1. TAJR335K016RNJ — Upgrade substitute with higher voltage rating (16 V) and tighter tolerance (±10%)
2. TCP1A335M8R — Direct equivalent with matching specifications but higher ESR (11.8 Ohm) and obsolete status

Parameter Comparison

Engineering Selection Recommendations

TAJR335K016RNJ is the preferred upgrade substitute. It maintains identical capacitance and ESR characteristics while providing 60% higher voltage headroom (16 V vs. 10 V). The tighter tolerance specification (±10%) offers improved circuit performance. Both components carry Active product status and full ROHS3 compliance. Physical dimensions remain compatible with 0805 footprints, with slightly reduced seated height (1.20mm vs. 1.50mm).

TCP1A335M8R functions as a direct electrical equivalent but carries "Not For New Designs" status, indicating obsolescence. The elevated ESR specification (11.8 Ohm vs. 5 Ohm) may impact performance in noise-sensitive applications. This part should be used only for legacy system maintenance or repair scenarios where original specifications must be preserved.

Frequently Asked Questions (FAQ)

Q: Can TAJR335K016RNJ replace TACR335M010R in all applications?

A: Yes. The higher voltage rating (16 V) provides backward compatibility with 10 V circuits. The tighter tolerance (±10%) and identical ESR ensure equivalent or improved performance. Physical dimensions are compatible with standard 0805 footprints.

Q: What is the primary difference between the two substitutes?

A: TAJR335K016RNJ is an active, upgraded component with higher voltage and tighter tolerance. TCP1A335M8R is electrically equivalent but obsolete (Not For New Designs) and exhibits higher ESR (11.8 Ohm), making it unsuitable for new designs.

Q: Are there any PCB layout considerations when switching between these parts?

A: All three parts use the 0805 (2012 Metric) package. Seated heights vary slightly (1.50mm, 1.20mm, 1.20mm respectively), but remain within standard surface mount assembly tolerances. No PCB redesign is required.

Q: Do all parts meet the same compliance standards?

A: Yes. TACR335M010R, TAJR335K016RNJ, and TCP1A335M8R are all ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: Which substitute should be selected for new product designs?

A: TAJR335K016RNJ is the only appropriate choice for new designs, as it carries Active product status. TCP1A335M8R is explicitly marked "Not For New Designs" and should not be used in new development.
