Key Parameters

Substitute Part Grouping Explanation

Substitution for the TCFGP1A475M8R is determined by strict equivalence across the following parameters:

• Capacitance value: 4.7 µF
• Tolerance: ±20%
• Voltage rating: 10 V
• Package type: 0805 (2012 Metric)
• Mounting type: Surface Mount
• Operating temperature range: -55°C to 125°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Both identified substitute parts meet these core electrical and mechanical requirements. Differences in ESR (Equivalent Series Resistance) and manufacturer size codes do not preclude substitution, as these parameters fall within acceptable ranges for general-purpose tantalum capacitor applications.

Parameter Comparison

Engineering Selection Recommendations

Both TAJR475M010RNJ and TPSR475M010R3000 are direct electrical and mechanical equivalents to the TCFGP1A475M8R. Selection between these two active alternatives should be based on the following factors:

TAJR475M010RNJ (TAJ series) provides a general-purpose molded tantalum capacitor with 9 Ohm ESR and maintains active product status with 4600 units in stock.

TPSR475M010R3000 (TPS series) offers lower ESR at 3 Ohm, which may provide performance advantages in applications sensitive to impedance characteristics. This part maintains active status with 1460 units in stock.

Both parts satisfy ROHS3 compliance and MSL 1 requirements. The choice between them depends on circuit-specific ESR requirements and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can TAJR475M010RNJ or TPSR475M010R3000 be used as direct replacements for TCFGP1A475M8R?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical capacitance (4.7 µF), tolerance (±20%), voltage rating (10 V), package type (0805), and operating temperature range (-55°C to 125°C).

Q: What is the significance of the different ESR values?

A: ESR (Equivalent Series Resistance) affects impedance characteristics at high frequencies. TPSR475M010R3000 has lower ESR (3 Ohm) compared to TAJR475M010RNJ (9 Ohm). For most general-purpose applications, both values are acceptable. Applications requiring specific impedance performance should verify ESR compatibility with circuit requirements.

Q: Are there physical size differences between these parts?

A: Minor dimensional variations exist. The TCFGP1A475M8R measures 0.079" L x 0.049" W (2.00mm x 1.25mm), while both KYOCERA AVX substitutes measure 0.081" L x 0.051" W (2.05mm x 1.30mm). All three parts maintain the same maximum seated height of 0.047" (1.20mm) and are compatible with 0805 (2012 Metric) footprints.

Q: Do these substitutes meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are REACH unaffected. Compliance requirements are identical across all three parts.

Q: Which substitute should be selected for new designs?

A: Both TAJR475M010RNJ and TPSR475M010R3000 are active products suitable for new designs. TPSR475M010R3000 may be preferred if lower ESR provides circuit performance benefits. TAJR475M010RNJ is suitable for general-purpose applications where ESR is not a critical parameter.
