Key Parameters

Substitute Part Grouping Explanation

Substitution for the TACT227M003XTA is determined by the following critical parameters:

• Capacitance Value: 220 µF (must match exactly)
• Tolerance: ±20% (must match exactly)
• Package / Case: 1411 (3528 Metric), 1210 (must match for mechanical compatibility)
• Physical Dimensions: 0.138" L x 0.110" W, 0.047" max height (must match for PCB layout)
• Mounting Type: Surface Mount (must match)
• Operating Temperature Range: -55°C ~ 125°C (must match or exceed)
• Voltage Rating: Must be equal to or greater than 3 V (higher voltage ratings are acceptable in the same package)
• Type: Molded tantalum (must match)

The substitute part TLJT227M004R1100 meets all mechanical and electrical compatibility criteria. The primary difference is an increased voltage rating (4 V versus 3 V), which is acceptable for direct substitution in applications designed for 3 V operation.

Parameter Comparison

Engineering Selection Recommendations

The TLJT227M004R1100 is the qualified substitute for the obsolete TACT227M003XTA. Both parts are manufactured by KYOCERA AVX and maintain identical mechanical compatibility through matching package dimensions and mounting specifications. Both components are ROHS3 compliant and REACH unaffected, satisfying regulatory requirements for current production environments.

The substitute part features a higher voltage rating (4 V) while maintaining the same capacitance value and tolerance. This higher voltage rating does not compromise functionality in circuits designed for 3 V operation and provides additional design margin. The ESR difference (1.1 Ohm versus 1 Ohm) is within acceptable engineering tolerance for general-purpose applications.

The TLJT227M004R1100 is currently in active production status with substantial inventory availability, ensuring supply chain continuity. The increased moisture sensitivity level (MSL 3 versus MSL 1) requires standard handling procedures during assembly but does not affect end-use performance.

Frequently Asked Questions (FAQ)

Q: Can the TLJT227M004R1100 be used as a direct replacement for the TACT227M003XTA?

A: Yes. Both parts share identical capacitance (220 µF), tolerance (±20%), package dimensions (1411/3528 Metric), and operating temperature range (-55°C to 125°C). The substitute part's higher voltage rating (4 V) is compatible with 3 V circuit designs.

Q: What is the significance of the voltage rating difference?

A: The substitute part is rated for 4 V operation, while the original part is rated for 3 V. A higher voltage rating provides additional safety margin and does not negatively affect performance in 3 V applications. The component will operate reliably at or below its rated voltage.

Q: Are there any handling differences due to the MSL rating change?

A: The substitute part has an MSL rating of 3 (168 hours) compared to the original part's MSL 1 (unlimited). This means the substitute part requires standard moisture control during storage and assembly. Standard industry practices for MSL 3 components are sufficient; no special procedures beyond normal handling are required.

Q: Do the physical dimensions match exactly?

A: Yes. Both parts use the 1411 (3528 Metric) package with identical dimensions: 0.138" L x 0.110" W (4.60mm x 2.80mm) and maximum seated height of 0.047" (1.20mm). PCB layouts and mechanical designs require no modification.

Q: What is the ESR difference between these parts?

A: The substitute part has an ESR of 1.1 Ohm compared to the original part's 1 Ohm. This 0.1 Ohm difference is negligible for general-purpose applications and does not affect circuit performance in typical filtering or energy storage applications.

Q: Why is the original part obsolete?

A: The TACT227M003XTA is classified as obsolete by the manufacturer. The TLJT227M004R1100 represents the current production equivalent, ensuring access to active inventory and ongoing manufacturing support.
