Key Parameters

Substitute Part Grouping Explanation

Substitution of the TAC225K050P05-F is determined by strict equivalence across the following parameters:

Primary Equivalence Criteria:

• Capacitance: 2.2 µF (exact match required)
• Voltage Rating: 50 V (exact match required)
• Type: Molded Tantalum (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Axial (exact match required)
• Physical Dimensions: 0.180" Dia x 0.345" L (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

Secondary Tolerance Consideration:

• Tolerance: ±10% is the baseline specification. Parts with ±5% tolerance (tighter tolerance) are classified as upgrades and are electrically compatible with circuits designed for ±10% tolerance.

All substitute parts listed meet these criteria. The TAC225K050P05-F obsolescence status makes active-status alternatives necessary for design continuity.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (±10% Tolerance):

The following parts are direct electrical and mechanical equivalents to the TAC225K050P05-F:

• 173D225X9050WE3 (Vishay Sprague TANTALEX™ 173D series, Tape & Box packaging)
• 173D225X9050WWE3 (Vishay Sprague TANTALEX™ 173D series, Tape & Reel packaging)
• T322C225K050AT (KEMET T322 series, Bulk packaging)

All three parts are active-status components with ROHS3 compliance and identical electrical specifications. Selection among these three is determined by packaging requirements: Tape & Box for manual assembly operations, Tape & Reel for automated pick-and-place systems, or Bulk for general stock applications.

Upgrade Option (±5% Tolerance):

• 173D225X5050WE3 (Vishay Sprague TANTALEX™ 173D series, Tape & Reel packaging)

This part provides tighter tolerance (±5% versus ±10%) while maintaining all other electrical and mechanical parameters. Circuits designed for ±10% tolerance operate within specification with this upgrade component. Selection of this upgrade is appropriate when improved capacitance accuracy is required or when design margins benefit from tighter tolerance control.

Compliance and Availability:

All substitute parts carry ROHS3 compliance certification, matching the original part specification. Current inventory levels across all substitutes exceed 800 units, ensuring supply continuity for production and repair applications.

Frequently Asked Questions (FAQ)

Q: Can 173D225X9050WE3 and 173D225X9050WWE3 be used interchangeably?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: Tape & Box (WE3) versus Tape & Reel (WWE3). Selection depends on assembly process requirements. Tape & Reel is standard for automated assembly; Tape & Box is suitable for manual assembly or lower-volume applications.

Q: Is T322C225K050AT a suitable replacement for TAC225K050P05-F?

A: Yes. The T322C225K050AT meets all electrical and mechanical equivalence criteria. The specified ESR of 3.5 Ohm is an additional performance characteristic not provided for the original part, but does not affect substitution compatibility. KEMET T322 series tantalum capacitors are widely used in industrial and commercial applications.

Q: What is the difference between the ±10% and ±5% tolerance parts?

A: The 173D225X5050WE3 provides ±5% tolerance compared to ±10% for other substitutes. This means the actual capacitance value will be closer to the nominal 2.2 µF specification. Circuits designed for ±10% tolerance operate within specification with the ±5% part. Use the ±5% upgrade when design requirements demand tighter capacitance accuracy or when circuit performance benefits from reduced tolerance variation.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the original TAC225K050P05-F specification. This ensures compatibility with RoHS-regulated supply chains and end-use applications.

Q: What packaging options are available?

A: Three packaging formats are available across the substitute parts: Tape & Box (TB) for manual assembly, Tape & Reel (TR) for automated assembly systems, and Bulk for general stock applications. Select based on your assembly process and inventory management requirements.

Q: Can these parts be used in high-temperature applications?

A: Yes. All parts, including the original and all substitutes, are rated for -55°C to 125°C operating temperature range. This specification applies to all listed components and supports use in industrial and automotive temperature environments within this range.

Q: Is the TAC225K050P05-F still available?

A: The TAC225K050P05-F is classified as obsolete. Inventory of 860 units is currently available, but no new production is expected. For new designs and ongoing production, use one of the active-status substitute parts listed in this document.
