Key Parameters

Substitute Part Grouping Explanation

The substitute part TAJB475K035RNJ is functionally equivalent based on the following critical parameters:

• Capacitance: 4.7 µF (derived from part designation context)
• Voltage Rating: 35 V
• Type: Molded Tantalum Capacitor
• Mounting Type: Surface Mount
• Manufacturer: KYOCERA AVX (same manufacturer)
• Compliance: Both parts share ECCN EAR99 and HTSUS 8532.21.0050 classification
• MSL Rating: 1 (Unlimited) for both parts

The TAJB475K035RNJ differs in packaging configuration (Cut Tape & Digi-Reel® versus Bulk) and provides additional technical specifications including ESR, operating temperature range, and package dimensions.

Parameter Comparison

Engineering Selection Recommendations

Compliance Consideration: The TAJB475K035RNJ is ROHS3 compliant, whereas the CWR11MH475JD is RoHS non-compliant. Applications requiring RoHS compliance must use the substitute part.

Packaging: The CWR11MH475JD is supplied in Bulk packaging, while the TAJB475K035RNJ is available in Cut Tape and Digi-Reel® configurations. Selection depends on assembly process requirements and minimum order quantity constraints.

Inventory Availability: The TAJB475K035RNJ has significantly higher stock availability (17,683 pcs) compared to the CWR11MH475JD (846 pcs), making it the preferred choice for applications without strict original part number requirements.

Both parts share identical MSL ratings, ECCN classification, and HTSUS codes, making them suitable for equivalent electrical and regulatory purposes within their respective compliance frameworks.

Frequently Asked Questions (FAQ)

Q: Can TAJB475K035RNJ be used as a direct replacement for CWR11MH475JD?

A: Yes, provided compliance requirements align. Both are KYOCERA AVX tantalum capacitors with matching electrical designations (4.7 µF, 35 V). The primary distinction is RoHS compliance status: TAJB475K035RNJ is ROHS3 compliant while CWR11MH475JD is non-compliant. Selection depends on application regulatory requirements.

Q: What is the significance of the packaging difference?

A: CWR11MH475JD is supplied in Bulk packaging, suitable for high-volume direct pick-and-place assembly. TAJB475K035RNJ is available in Cut Tape and Digi-Reel® formats, which are standard for automated assembly lines and lower-volume orders. Packaging choice does not affect electrical or mechanical performance.

Q: Are there any operating condition limitations for either part?

A: Both parts carry MSL 1 (Unlimited) ratings, indicating no moisture sensitivity restrictions. The TAJB475K035RNJ specifies an operating temperature range of -55°C to 125°C. The CWR11MH475JD does not provide a detailed operating range in the available specifications.

Q: What does RoHS compliance mean in terms of part substitution?

A: RoHS compliance restricts the use of certain hazardous substances in electrical components. TAJB475K035RNJ meets ROHS3 standards, making it suitable for applications in regulated markets (EU, certain Asian markets). CWR11MH475JD, being non-compliant, is restricted to applications without RoHS mandates.

Q: Is the ESR specification important for selecting between these parts?

A: ESR (Equivalent Series Resistance) affects performance in high-frequency or noise-sensitive circuits. TAJB475K035RNJ specifies 3.1 Ohm ESR. The CWR11MH475JD does not provide an ESR value in available documentation. For applications requiring specific ESR performance, the TAJB475K035RNJ specification confirms acceptability at 3.1 Ohm.
