Substitute Part Grouping Explanation

Substitution eligibility for the TACL225K006R is determined by strict equivalence across the following critical parameters:

• Capacitance Value: Must be 2.2 µF (within ±10% tolerance specification)
• Voltage Rating: Must be 6.3 V or higher
• Package / Case: Must be 0603 (1608 Metric) surface mount
• Mounting Type: Must be surface mount compatible
• Operating Temperature Range: Must support -55°C to 125°C minimum
• Type: Must be molded tantalum construction
• Compliance: Must maintain RoHS3 compliance and REACH unaffected status

The identified substitute part TPCL225K006R5000 meets all critical substitution criteria. This part maintains identical capacitance, voltage rating, package geometry, and temperature operating range while offering improved ESR performance (5Ohm @ 100kHz versus 7.5Ohm) and documented lifetime rating (2000 Hrs @ 85°C).

Parameter Comparison

Engineering Selection Recommendations

Both TACL225K006R and TPCL225K006R5000 are active production components with full regulatory compliance. Selection between these parts should be based on the following factors:

TACL225K006R is appropriate for applications where standard ESR performance (7.5Ohm) is acceptable and component availability from existing inventory is prioritized.

TPCL225K006R5000 is appropriate for applications where lower ESR performance (5Ohm @ 100kHz) provides circuit performance benefits, documented lifetime rating (2000 Hrs @ 85°C) is required for reliability qualification, or higher inventory availability (3078 Pcs versus 1007 Pcs) supports supply chain continuity.

Both parts maintain identical electrical ratings, mechanical compatibility, and regulatory compliance status. Direct substitution is permissible without circuit redesign or board layout modification.

Frequently Asked Questions (FAQ)

Q: Can TPCL225K006R5000 be used as a direct replacement for TACL225K006R?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: 2.2 µF capacitance, 6.3 V rating, 0603 package, and -55°C to 125°C operating range. No circuit modification or board redesign is required.

Q: What is the difference in ESR between these parts?

A: TACL225K006R has 7.5Ohm ESR, while TPCL225K006R5000 has 5Ohm ESR @ 100kHz. The substitute part offers lower series resistance, which may improve performance in high-frequency or low-impedance applications.

Q: Are both parts RoHS3 compliant?

A: Yes. Both TACL225K006R and TPCL225K006R5000 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Do these parts have the same physical dimensions?

A: Yes. Both parts are 0603 (1608 Metric) surface mount packages with identical dimensions: 0.063" L x 0.033" W (1.60mm x 0.85mm) and maximum seated height of 0.039" (1.00mm). Board layout and footprint compatibility is maintained.

Q: What is the moisture sensitivity rating for these parts?

A: Both parts have MSL 1 (Unlimited) moisture sensitivity rating, indicating no moisture sensitivity restrictions for storage, handling, or reflow processing.

Q: Does TPCL225K006R5000 have a documented lifetime rating?

A: Yes. TPCL225K006R5000 is rated for 2000 Hrs @ 85°C, providing documented reliability data for qualification and long-term performance assessment. TACL225K006R does not specify a lifetime rating in the provided data.
