Key Parameters

Substitute Part Grouping Explanation

Substitution of the T495X687M006ATE060 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 680 µF (exact match required)
• Voltage Rating: 6.3 V (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)

Allowable Variation Parameters:

• Tolerance: ±20% or ±10% (tighter tolerance acceptable)
• ESR @ 100kHz: 60 mOhm, 100 mOhm, or 23 mOhm (lower ESR acceptable)
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel®
• RoHS Status: RoHS3 Compliant or RoHS non-compliant (compliance acceptable)

The substitute parts listed below meet all mandatory matching parameters and fall within allowable variation ranges for tolerance, ESR, and packaging format.

Parameter Comparison

Engineering Selection Recommendations

RoHS3 Compliant Substitutes (Preferred for New Designs):

T510X687M006ATE023 is the direct functional equivalent with identical tolerance (±20%) and superior ESR performance (23 mOhm vs. 60 mOhm). This part maintains RoHS3 compliance and offers the highest inventory availability (3863 pcs). Selection is appropriate when lower ESR is beneficial for circuit performance.

T494X687K006AT provides tighter tolerance (±10%) with moderate ESR improvement (100 mOhm) and RoHS3 compliance. This part is suitable for applications requiring improved capacitance accuracy.

T510X687K006ATE023 combines tighter tolerance (±10%) with superior ESR performance (23 mOhm) and RoHS3 compliance, offering the best overall electrical characteristics among compliant options.

T491X687K006AT maintains RoHS3 compliance with tighter tolerance (±10%) and offers alternative packaging format (Cut Tape & Digi-Reel®) for specific assembly requirements.

Non-Compliant Substitute (Legacy Applications Only):

T491X687K006AH is RoHS non-compliant and is suitable only for legacy or non-regulated applications. This part offers tighter tolerance (±10%) but does not meet current environmental compliance standards.

All substitute parts share identical capacitance (680 µF), voltage rating (6.3 V), package (2917 / 7343 Metric), and operating temperature range (-55°C to 125°C) with the main part.

Frequently Asked Questions (FAQ)

Q: Can T510X687M006ATE023 be used as a direct replacement for T495X687M006ATE060?

A: Yes. Both parts have identical capacitance (680 µF), voltage rating (6.3 V), tolerance (±20%), package (2917 / 7343 Metric), and operating temperature range (-55°C to 125°C). The T510X687M006ATE023 features lower ESR (23 mOhm vs. 60 mOhm), which is electrically compatible and often beneficial for circuit performance.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging?

A: Tape & Reel (TR) is continuous reel packaging for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® is pre-cut tape format suitable for lower-volume or mixed-component assembly. Both formats contain identical components; the difference is in delivery and handling format only.

Q: Why do some substitutes have ±10% tolerance instead of ±20%?

A: Tighter tolerance (±10%) represents improved capacitance accuracy compared to the original part (±20%). Parts with ±10% tolerance are electrically compatible and acceptable substitutes; they provide better capacitance stability for applications requiring tighter specifications.

Q: What does ESR (Equivalent Series Resistance) mean, and why does it vary among substitutes?

A: ESR is the internal resistance of the capacitor at 100 kHz. Lower ESR values (23 mOhm, 100 mOhm) indicate better high-frequency performance and lower heat generation compared to higher ESR values (60 mOhm, 600 mOhm). All listed substitutes are electrically compatible; lower ESR options provide improved performance characteristics.

Q: Is RoHS3 compliance required for my application?

A: RoHS3 compliance is mandatory for products sold in the European Union and many regulated markets. For new designs, RoHS3 compliant parts (T510X687M006ATE023, T494X687K006AT, T510X687K006ATE023, T491X687K006AT) are recommended. RoHS non-compliant parts (T491X687K006AH) are suitable only for legacy applications or non-regulated markets.

Q: Can I substitute a part with lower ESR without circuit redesign?

A: Yes. Lower ESR is electrically compatible and does not require circuit redesign. Lower ESR reduces heat generation and improves high-frequency performance, making it a safe substitution for applications using the original part.

Q: Are all substitute parts in the same 2917 (7343 Metric) package?

A: Yes. All substitute parts listed use the identical 2917 (7343 Metric) surface mount package with matching dimensions (0.287" L x 0.169" W / 7.30mm x 4.30mm) and height (0.169" / 4.30mm). No PCB layout modifications are required.
