TARS226M006 Equivalent & Substitute Parts

Part Overview

The TARS226M006 is a 22 µF molded tantalum capacitor manufactured by KYOCERA AVX, rated for 6.3 V with ±20% tolerance and 3.7Ohm equivalent series resistance. This component is classified as obsolete, making substitute parts necessary for new designs and ongoing production requirements. The axial through-hole configuration and general-purpose application profile allow for direct substitution with compatible alternatives meeting the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TARS226M006 is determined by the following criteria:

Mandatory Parameters (Must Match or Exceed):

• Capacitance: 22 µF (exact match required)
• Voltage Rating: Minimum 6.3 V (higher ratings acceptable)
• Tolerance: ±20% or better (±10% acceptable as improvement)
• Type: Molded Tantalum (same technology)
• Mounting Type: Through Hole (same mounting method)
• Package: Axial (same form factor)
• Operating Temperature Range: -55°C to 125°C (minimum requirement)

Acceptable Variations:

• Voltage rating may be increased above 6.3 V for improved design margin
• Tolerance may be tightened from ±20% to ±10%
• ESR values may differ based on manufacturer specifications
• Physical dimensions may vary within axial package constraints
• Packaging format (Tape & Reel or Bulk) does not affect electrical compatibility

The three substitute parts listed below meet all mandatory parameters and represent active or available alternatives to the obsolete TARS226M006.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are qualified alternatives to the TARS226M006 based on electrical parameter compatibility and active product status.

173D226X0010WW (Vishay Sprague TANTALEX™ 173D Series): Maintains ±20% tolerance matching the original specification while providing 10 V voltage rating. Active product status ensures long-term availability. Suitable for direct substitution where tolerance and voltage margin are acceptable.

173D226X9010WW (Vishay Sprague TANTALEX™ 173D Series): Offers improved ±10% tolerance with 10 V voltage rating. Active product status provides supply continuity. Recommended where tighter tolerance control is required without changing core electrical characteristics.

T322C226K010AS (KEMET T322 Series): Provides ±10% tolerance, 10 V voltage rating, and specified 2.7Ohm ESR (lower than original 3.7Ohm). Active product status ensures availability. Bulk packaging format differs from tape & reel options. Suitable for applications where lower ESR is beneficial.

All substitute parts maintain the -55°C to 125°C operating temperature range and through-hole axial mounting configuration. Physical dimensions show minor increases (0.180" diameter vs. 0.169", 0.345" length vs. 0.339") within acceptable PCB layout tolerances for axial components.

Frequently Asked Questions (FAQ)

Q: Can I use a 10 V rated capacitor in place of the 6.3 V TARS226M006?

A: Yes. The substitute parts rated for 10 V exceed the original 6.3 V requirement and provide additional voltage margin. This is an acceptable substitution practice in capacitor selection.

Q: What is the difference between the two Vishay Sprague options?

A: 173D226X0010WW maintains ±20% tolerance identical to the original part. 173D226X9010WW provides tighter ±10% tolerance. Both are 10 V rated and active products. Selection depends on tolerance requirements for your application.

Q: Why does the KEMET T322C226K010AS have lower ESR than the original?

A: ESR varies by manufacturer design and construction. The KEMET part specifies 2.7Ohm compared to the original 3.7Ohm. Lower ESR can reduce heat generation and improve high-frequency performance, though both values are acceptable for general-purpose applications.

Q: Are there physical size differences I need to consider?

A: Yes. The substitute parts are slightly larger: 0.180" diameter and 0.345" length versus the original 0.169" diameter and 0.339" length. Verify PCB layout clearances for axial component spacing before implementation.

Q: What is the difference between Tape & Reel and Bulk packaging?

A: Tape & Reel packaging is used for automated assembly processes. Bulk packaging is used for manual assembly or smaller production runs. Electrical performance is identical; packaging format affects procurement and assembly methods only.

Q: Are all substitute parts RoHS compliant?

A: No. All parts listed, including substitutes, are RoHS non-compliant. If RoHS compliance is required, alternative component families must be evaluated separately.
