Electrical Parameters:

• Capacitance value and tolerance
• Voltage rating
• Equivalent Series Resistance (ESR)
• Operating temperature range
• Lifetime rating at elevated temperature

Mechanical Parameters:

• Package type and case size
• Mounting configuration (Surface Mount)
• Physical dimensions and height constraints
• Lead spacing and footprint compatibility

Compliance Parameters:

• RoHS compliance status
• REACH compliance status
• ECCN classification
• HTSUS tariff code alignment

The identified substitute part 2R5TPE220MAPB from Panasonic Electronic Components meets the established substitution criteria based on matching electrical characteristics, mechanical compatibility, and regulatory compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the T520B227M2R5ATE025 and 2R5TPE220MAPB are active products with ROHS3 compliance and identical ECCN/HTSUS classifications. The substitute part maintains the same electrical rating (220 µF at 2.5 V) and surface mount configuration.

Selection between these parts should be based on:

• Availability and lead time: The main part has 7450 units in stock; the substitute has 1200 units available
• Regulatory compliance: Both parts satisfy ROHS3 and REACH requirements
• Supply chain continuity: Use the substitute when the primary part is unavailable or when procurement optimization is required
• Footprint compatibility: Verify that the 1411 (3528 Metric) package dimensions align with the PCB layout requirements

Frequently Asked Questions (FAQ)

Q: Can the 2R5TPE220MAPB directly replace the T520B227M2R5ATE025?

A: Yes, based on matching capacitance (220 µF), voltage rating (2.5 V), surface mount configuration, and compliance certifications (ROHS3, EAR99, HTSUS 8532.21.0050). Verify PCB footprint compatibility with the 1411 (3528 Metric) package dimensions.

Q: What are the key electrical parameters that determine substitutability?

A: Capacitance value, voltage rating, and ESR characteristics are the primary electrical parameters. Both parts are rated at 220 µF and 2.5 V. The substitute specifies 25 mOhm ESR at 100 kHz.

Q: Are there any compliance concerns with using the substitute part?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified under identical ECCN (EAR99) and HTSUS (8532.21.0050) codes.

Q: What is the package compatibility consideration?

A: The substitute part uses a 1411 (3528 Metric) case with dimensions of 0.138" L x 0.110" W and maximum seated height of 0.079". Confirm these dimensions fit the PCB layout and assembly requirements.

Q: What is the moisture sensitivity level of the substitute part?

A: The substitute part's MSL is not specified in the provided data. The main part is rated MSL 3 (168 Hours). Obtain complete MSL specifications from the manufacturer if moisture sensitivity is a critical design parameter.
