Key Parameters

Substitute Part Grouping Explanation

Substitution of the T496B475M016AS is determined by strict equivalence in the following parameters: capacitance value (4.7 µF), voltage rating (16 V), package type (1411 / 3528 Metric), mounting configuration (Surface Mount), and physical dimensions (0.138" L x 0.110" W, 2.10mm max height). The tolerance specification (±20%) and ESR characteristics are secondary parameters that may vary within acceptable engineering limits for the application.

Two substitute parts are identified:

Direct Manufacturer Equivalent: T496B475M016ATE3K5 maintains identical capacitance, voltage, tolerance, and package specifications while adding specified ESR (3.5Ohm) and lifetime rating (2000 Hrs @ 85°C). This part is active and RoHS3 compliant.

Parametric Equivalent: T496B475K016ATE3K5 shares all primary electrical and mechanical parameters with the main part but features tighter tolerance (±10% versus ±20%) and identical ESR and lifetime specifications. This part is also active and RoHS3 compliant.

Parameter Comparison

Engineering Selection Recommendations

T496B475M016ATE3K5 is the primary substitute for the obsolete T496B475M016AS. This part provides direct electrical and mechanical compatibility while offering active product status and RoHS3 compliance. The addition of specified ESR (3.5 Ohm) and lifetime rating (2000 Hrs @ 85°C) provides enhanced reliability documentation. Tape & Reel packaging supports automated assembly processes.

T496B475K016ATE3K5 serves as an alternative when tighter capacitance tolerance (±10%) is required by circuit design specifications. This part maintains all other electrical and mechanical parameters identical to the main part and direct equivalent, with the same active status and RoHS3 compliance.

Both substitute parts are suitable for direct replacement in applications where the original T496B475M016AS was specified, provided that the tolerance and ESR specifications align with circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can T496B475M016ATE3K5 be used as a direct replacement for T496B475M016AS?

A: Yes. Both parts share identical capacitance (4.7 µF), voltage rating (16 V), tolerance (±20%), package type (1411 / 3528 Metric), and physical dimensions. The substitute part is active and RoHS3 compliant, addressing the obsolescence of the original part.

Q: What is the difference between T496B475M016ATE3K5 and T496B475K016ATE3K5?

A: The primary difference is capacitance tolerance. T496B475M016ATE3K5 has ±20% tolerance, matching the original part. T496B475K016ATE3K5 has ±10% tolerance, providing tighter capacitance accuracy. Both parts have identical voltage rating, package, ESR, and operating temperature range.

Q: Are the substitute parts available in different packaging formats?

A: Both substitute parts are supplied in Tape & Reel (TR) packaging, suitable for automated assembly. The original part packaging format was not specified in the available data.

Q: Do the substitute parts meet RoHS requirements?

A: Yes. Both T496B475M016ATE3K5 and T496B475K016ATE3K5 are RoHS3 compliant, whereas the original T496B475M016AS is RoHS non-compliant.

Q: What is the ESR specification for the original T496B475M016AS?

A: The ESR for the original part was not specified in the available documentation. Both substitute parts specify 3.5 Ohm ESR, providing defined electrical characteristics for circuit design.

Q: Can these parts be used interchangeably in the same circuit board design?

A: Yes, provided that the circuit design accommodates the specified tolerance and ESR values. The identical package type and physical dimensions ensure mechanical compatibility and identical PCB footprints.
