Substitute Part Grouping Explanation

Substitution of the T496D107K010AS is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance Value: 100 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating: 10 V (exact match required)
• Package Type: 2917 (7343 Metric) surface mount (exact match required)
• Physical Dimensions: 0.287" L x 0.169" W x 0.122" H maximum (exact match required)
• Component Type: Molded tantalum capacitor (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Protective Features: Fail-safe design with built-in fuse (exact match required)

The T496D107K010AT qualifies as a direct substitute based on complete alignment with all specified electrical and mechanical parameters. The primary distinction between the main part and its substitute is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The T496D107K010AT is the direct equivalent substitute for the obsolete T496D107K010AS. Both components share identical electrical specifications, physical dimensions, and functional characteristics. The substitute part offers the following advantages:

Product Status: The T496D107K010AT maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Packaging Configuration: The substitute is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes. The main part is supplied in bulk packaging.

Reliability Data: The T496D107K010AT includes specified lifetime rating of 2000 hours at 85°C, providing documented reliability performance data.

Selection of the T496D107K010AT is appropriate for all applications previously designed with the T496D107K010AS, with no circuit modifications or re-qualification required.

Frequently Asked Questions (FAQ)

Q: Can the T496D107K010AT be used as a direct replacement for the T496D107K010AS in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. No circuit modifications are required. The substitute maintains the same capacitance value (100 µF), voltage rating (10 V), tolerance (±10%), package type (2917), physical dimensions, operating temperature range (-55°C to 125°C), and fail-safe protection features.

Q: What is the significance of the packaging difference between these parts?

A: The main part (T496D107K010AS) is supplied in bulk packaging, while the substitute (T496D107K010AT) is supplied in Tape & Reel (TR) format. Tape & Reel packaging is optimized for automated surface mount assembly processes and is the standard format for production environments. Both packaging formats contain the same component.

Q: Does the RoHS compliance difference affect component functionality?

A: No. RoHS compliance status reflects manufacturing process and material composition standards, not electrical or mechanical performance. The ROHS3 compliance of the T496D107K010AT indicates adherence to current environmental regulations. For applications subject to RoHS requirements, the substitute part is the appropriate selection.

Q: Are the physical dimensions identical between the two parts?

A: Yes. Both the T496D107K010AS and T496D107K010AT share identical dimensions: 0.287" length x 0.169" width (7.30mm x 4.30mm), with a maximum seated height of 0.122" (3.10mm). PCB footprints and assembly specifications are interchangeable.

Q: What does the lifetime rating of 2000 Hrs @ 85°C indicate for the substitute part?

A: This specification documents the expected operational lifetime of the T496D107K010AT under elevated temperature conditions (85°C). This reliability data is provided for the substitute part but not specified for the obsolete main part. This information supports design validation and long-term reliability assessments.

Q: Are there any restrictions on using the T496D107K010AT in place of the T496D107K010AS?

A: No restrictions exist. The parts are functionally equivalent across all electrical, mechanical, and environmental parameters. The substitute is suitable for all applications previously designed with the main part.
