Substitute Part Grouping Explanation

Substitution of the T510X687M004AS is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 680 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage rating: 4 V (exact match required)
• ESR: 30 mOhm (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)

Mechanical Parameters:

• Package type: 2917 (7343 Metric) surface mount (exact match required)
• Physical dimensions: 0.287" L x 0.169" W / 7.30 mm x 4.30 mm (exact match required)
• Height seated maximum: 0.169" (4.30 mm) (exact match required)
• Manufacturer size code: X (exact match required)

Material & Construction:

• Type: Molded tantalum (exact match required)
• Features: General Purpose (exact match required)

The substitute part T510X687M004ATE030 meets all electrical, mechanical, and construction criteria for direct substitution. The primary difference is product status (active versus obsolete) and packaging format (Tape & Reel versus bulk), along with enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The T510X687M004ATE030 is the direct substitute for the obsolete T510X687M004AS. Both parts are manufactured by KEMET within the T510 series and share identical electrical and mechanical specifications across all critical parameters: 680 µF capacitance, ±20% tolerance, 4 V rating, 30 mOhm ESR, and 2917 (7343 Metric) package dimensions.

Product Status Consideration: The main part is classified as obsolete, while the substitute is active. This distinction is significant for procurement and long-term supply chain planning. Active status ensures ongoing availability and manufacturing support.

Compliance Advantage: The substitute part T510X687M004ATE030 carries ROHS3 compliance certification, whereas the main part is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements, the substitute provides regulatory alignment. Both parts maintain REACH Unaffected and EAR99 ECCN classifications.

Packaging Consideration: The main part is supplied in bulk packaging, while the substitute is available in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes and provides improved handling and traceability for production environments.

Reliability Data: The substitute part includes specified lifetime data (2000 Hrs @ 85°C), providing quantified reliability information absent from the main part specification.

For new designs, production continuity, or component replacement, the T510X687M004ATE030 is the appropriate selection based on active product status, enhanced compliance certifications, and equivalent electrical and mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can T510X687M004ATE030 be used as a direct replacement for T510X687M004AS in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters: 680 µF capacitance, ±20% tolerance, 4 V rating, 30 mOhm ESR, -55°C to 125°C operating range, and 2917 (7343 Metric) package dimensions. No circuit modifications or board layout changes are required.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: Product status indicates manufacturing and supply availability. The main part (T510X687M004AS) is obsolete and no longer manufactured by KEMET. The substitute (T510X687M004ATE030) is active, ensuring continued availability, manufacturing support, and consistent quality control. For ongoing production or new designs, the active part is the appropriate choice.

Q: Does the RoHS3 compliance of the substitute part affect compatibility?

A: No. RoHS3 compliance is a regulatory and environmental certification that does not alter electrical or mechanical performance. The substitute's RoHS3 status is an advantage for applications subject to RoHS regulations or customer environmental requirements. Both parts maintain identical functional characteristics.

Q: What is the difference between bulk packaging and Tape & Reel (TR) packaging?

A: Bulk packaging is used for manual handling and smaller quantities. Tape & Reel packaging is the standard format for automated assembly processes, providing components on continuous tape for pick-and-place equipment. Tape & Reel format improves production efficiency, traceability, and handling consistency in manufacturing environments.

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

A: Yes. Both parts share identical dimensions: 0.287" L x 0.169" W (7.30 mm x 4.30 mm) with a maximum seated height of 0.169" (4.30 mm). No PCB layout modifications are necessary when substituting between these parts.

Q: What does the Manufacturer Size Code "X" indicate?

A: The size code "X" is KEMET's designation for the 2917 (7343 Metric) package format. Both the main part and substitute use this identical size code, confirming package equivalence.

Q: Is the 30 mOhm ESR specification critical for substitution?

A: Yes. ESR is a critical electrical parameter that affects circuit performance, particularly in filtering and power delivery applications. Both parts specify 30 mOhm ESR, ensuring equivalent electrical behavior in the circuit.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the lowest moisture sensitivity level. Components with MSL 1 have unlimited shelf life and do not require special moisture control during storage or handling. Both parts carry this classification, indicating robust moisture resistance.
