Key Parameters

Substitute Part Grouping Explanation

Substitution of the T496B475M010AS is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance: 4.7 µF (exact match required)
• Voltage Rating: 10 V (exact match required)
• Type: Molded Tantalum (exact match required)

Mechanical Parameters:

• Package / Case: 1411 (3528 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Physical Dimensions: 0.138" L x 0.110" W x 0.083" H maximum (exact match required)

Environmental Parameters:

• Operating Temperature Range: -55°C to 125°C (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Substitute parts are grouped into two categories: Direct Manufacturer Substitutes (identical specifications with active product status) and Parametric Equivalents (matching core electrical and mechanical parameters with tolerance variations). All substitute parts maintain the fail-safe fuse feature and identical physical footprint, ensuring direct replacement capability in existing PCB designs.

Parameter Comparison

Engineering Selection Recommendations

T496B475M010AT is the primary direct manufacturer substitute. This part maintains identical electrical specifications (4.7 µF, ±20% tolerance, 10 V rating) and mechanical configuration (1411 package, surface mount) as the obsolete T496B475M010AS. The T496B475M010AT carries active product status and ROHS3 compliance certification, addressing the obsolescence and regulatory limitations of the original part. ESR specification of 3.5 Ohm is documented for this substitute, providing additional design margin data not available for the main part.

T496B475K010AT serves as a parametric equivalent with tighter capacitance tolerance (±10% versus ±20%). This part is suitable for applications requiring improved capacitance accuracy while maintaining all other electrical and mechanical parameters. ROHS3 compliance and active product status are confirmed. The ±10% tolerance represents a more stringent specification than the original part.

T496B475M010ATE3K5 is functionally identical to T496B475M010AT with matching electrical specifications and tolerance. This variant carries active product status and ROHS3 compliance. The highest inventory availability (6112 units) among all substitutes supports supply chain continuity for production applications.

All three substitute parts are REACH Unaffected and classified under ECCN EAR99, maintaining the same regulatory classification as the original component. Selection between substitutes should be based on tolerance requirements, inventory availability, and packaging format (Tape & Reel for all active substitutes).

Frequently Asked Questions (FAQ)

Q: Can T496B475M010AT directly replace T496B475M010AS in existing designs?

A: Yes. The T496B475M010AT maintains identical capacitance (4.7 µF), voltage rating (10 V), tolerance (±20%), package (1411), and physical dimensions. Direct PCB-level substitution is supported without design modification.

Q: What is the difference between T496B475M010AT and T496B475K010AT?

A: The primary difference is capacitance tolerance. T496B475M010AT specifies ±20% tolerance, while T496B475K010AT specifies ±10% tolerance. Both parts share identical voltage rating, package, and operating temperature range. Selection depends on circuit tolerance requirements.

Q: Why are the substitute parts listed as ROHS3 Compliant while the original is RoHS non-compliant?

A: The T496B475M010AS is classified as obsolete and predates current RoHS3 compliance requirements. The active substitute parts (T496B475M010AT, T496B475K010AT, T496B475M010ATE3K5) meet current ROHS3 standards, making them suitable for new designs and applications subject to RoHS regulations.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All three substitute parts are supplied in Tape & Reel (TR) packaging format, suitable for automated assembly processes. The original T496B475M010AS packaging format is not specified in the provided data.

Q: What is the significance of the ESR specification in the substitute parts?

A: The substitute parts specify 3.5 Ohm ESR (Equivalent Series Resistance), providing documented impedance characteristics for circuit design calculations. The original part does not include ESR specification. This parameter is relevant for high-frequency applications and ripple current considerations.

Q: Can T496B475M010ATE3K5 be used interchangeably with T496B475M010AT?

A: Yes. Both parts are functionally equivalent with identical electrical specifications (4.7 µF, ±20%, 10 V), mechanical configuration (1411 package), and operating characteristics. Selection between these parts may be based on inventory availability or supplier preference.

Q: What is the Lifetime @ Temp. specification, and why is it important?

A: The substitute parts specify 2000 Hours @ 85°C lifetime rating, indicating expected operational duration under elevated temperature conditions. This specification supports reliability analysis for applications operating in high-temperature environments. The original part does not include this specification.

Q: Are there any restrictions on using these substitute parts in REACH-regulated applications?

A: No. All parts, including the original T496B475M010AS and all substitutes, are classified as REACH Unaffected, indicating no restrictions under REACH regulations.
