TAC225K025P02-F Equivalent & Substitute Parts

Part Overview

The TAC225K025P02-F is a 2.2 µF molded tantalum capacitor rated at 25 V with ±10% tolerance, manufactured by Cornell Dubilier Electronics (CDE). This component is designed for general-purpose applications requiring axial through-hole mounting. The part is currently obsolete, necessitating identification of functionally equivalent alternatives from active manufacturers to maintain design continuity and ensure component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TAC225K025P02-F are qualified based on strict electrical and mechanical parameter matching:

Electrical Parameters (Non-negotiable):

• Capacitance: 2.2 µF
• Voltage Rating: 25 V
• Tolerance: ±10%
• Type: Molded Tantalum

Mechanical Parameters (Non-negotiable):

• Mounting Type: Through Hole
• Package / Case: Axial
• Size / Dimension: 0.110" Dia x 0.290" L (2.79mm x 7.37mm)

Environmental & Compliance Parameters:

• Operating Temperature: -55°C ~ 125°C
• RoHS Status: ROHS3 Compliant

All three substitute parts meet these criteria and are sourced from active manufacturers with current production status.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 173D225X9025VWE3 (Vishay Sprague)

This part is the preferred substitute based on the following factors:

• Active product status with established manufacturing continuity
• Highest inventory availability (12,323 pcs) ensuring supply chain reliability
• Cut Tape (CT) packaging suitable for automated assembly processes
• ROHS3 compliance and REACH unaffected status
• Identical electrical and mechanical specifications to the original part

Secondary Recommendation: 173D225X9025VE3 (Vishay Sprague)

This part serves as an alternative with the following characteristics:

• Active product status from the same manufacturer as the primary recommendation
• Tape & Box (TB) packaging suitable for manual assembly or lower-volume applications
• Adequate inventory availability (715 pcs)
• Identical electrical and mechanical specifications

Tertiary Recommendation: T322B225K025AT (KEMET)

This part is suitable for applications where ESR specification is a design requirement:

• Active product status with established production
• Specified ESR of 6 Ohm (not specified for other alternatives)
• Bulk packaging suitable for high-volume procurement
• Adequate inventory availability (1,148 pcs)
• All electrical and mechanical parameters match the original specification

All three substitute parts are functionally equivalent for direct replacement in the TAC225K025P02-F application.

Frequently Asked Questions (FAQ)

Q: Can the 173D225X9025VWE3 be used as a direct replacement for the TAC225K025P02-F?

A: Yes. The 173D225X9025VWE3 meets all critical electrical and mechanical parameters: 2.2 µF capacitance, 25 V voltage rating, ±10% tolerance, molded tantalum type, through-hole axial mounting, and identical physical dimensions (0.110" Dia x 0.290" L). Both parts operate across the same temperature range (-55°C ~ 125°C) and comply with ROHS3 standards.

Q: What is the difference between the two Vishay Sprague parts (173D225X9025VE3 and 173D225X9025VWE3)?

A: The primary difference is packaging format. The 173D225X9025VWE3 is supplied in Cut Tape (CT) format, optimized for automated pick-and-place assembly. The 173D225X9025VE3 is supplied in Tape & Box (TB) format, suitable for manual assembly or lower-volume applications. Electrical and mechanical specifications are identical.

Q: Why is the T322B225K025AT listed as a substitute if it specifies 6 Ohm ESR while others do not?

A: The T322B225K025AT is a valid substitute because ESR specification is provided as additional technical data, not as a limiting parameter for substitution. The part meets all mandatory electrical and mechanical criteria. The specified ESR value may be beneficial for applications sensitive to impedance characteristics, but its presence does not disqualify the other alternatives.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All three substitute parts (173D225X9025VE3, 173D225X9025VWE3, and T322B225K025AT) are ROHS3 compliant. The original TAC225K025P02-F is also ROHS3 compliant.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes, for electrical function. All parts share identical physical dimensions (0.110" Dia x 0.290" L) and axial through-hole mounting configuration. However, packaging format differences (Cut Tape vs. Tape & Box vs. Bulk) affect procurement and assembly logistics, not PCB compatibility.

Q: What inventory considerations should guide part selection?

A: The 173D225X9025VWE3 offers the highest inventory availability (12,323 pcs), providing the strongest supply chain assurance. The T322B225K025AT (1,148 pcs) and 173D225X9025VE3 (715 pcs) provide adequate alternatives for applications with lower volume requirements or longer lead times.
