Substitute Part Grouping Explanation

Substitute parts for the 1879062-1 are categorized based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Critical Parameters for Direct Substitution:

Capacitance: 10 µF (exact match required)
Tolerance: ±10% (exact match required)
Voltage Rating: 6.3 V (exact match required)
Type: Molded tantalum (exact match required)
ESR: 2Ohm (exact match required)
Package: 1206 (3216 Metric) (exact match required)
Operating Temperature: -55°C ~ 125°C (exact match required)
Mounting Type: Surface Mount (exact match required)

Direct Substitutes meet all critical parameters and differ only in manufacturer, series designation, or packaging format. These parts are electrically and mechanically interchangeable.

Upgrade Parts maintain all critical electrical parameters but feature higher voltage ratings (10 V instead of 6.3 V). These parts are suitable for applications where the original 6.3 V rating is adequate, as higher-rated components operate within specification at lower applied voltages.

Similar Parts maintain the same capacitance, tolerance, voltage, package, and operating temperature but feature higher ESR values (3.4Ohm or 4Ohm versus 2Ohm). These parts are functionally compatible but exhibit different electrical characteristics in high-frequency or low-impedance applications.

Frequently Asked Questions (FAQ)

Q: Can I use a 10 V rated capacitor in place of the 6.3 V rated 1879062-1?

A: Yes. The upgrade parts 593D106X9010A2TE3 and TR3A106K010C2000 are rated at 10 V and maintain all other electrical specifications identical to the original part. Higher voltage-rated capacitors operate safely at lower applied voltages and provide additional design margin.

Q: What is the difference between direct substitutes and similar parts?

A: Direct substitutes (593D106X96R3A2TE3, T494A106K006AT, TR3A106K6R3C2000) maintain the exact 2Ohm ESR specification. Similar parts (293D106X96R3A2TE3, T491A106K006AT, TAJA106K006A, TAJA106K006RNJ) feature higher ESR values (3.4Ohm or 4Ohm). ESR affects impedance characteristics in high-frequency applications and power dissipation. Select direct substitutes for applications sensitive to ESR performance.

Q: Are all substitute parts RoHS3 compliant?

A: All substitute parts listed are RoHS3 compliant. The original 1879062-1 does not specify RoHS status. All active product alternatives meet current environmental compliance requirements.

Q: What packaging formats are available?

A: Substitute parts are available in the following formats: Tape & Reel (TR), Cut Tape (CT) & Digi-Reel®, and unspecified packaging. Select packaging format based on assembly equipment and production volume requirements.

Q: Can I use the conformal coated F951C106KSAAQ2 as a substitute?

A: The F951C106KSAAQ2 is electrically compatible (10 µF, ±10%, 2Ohm ESR, 1206 package) but differs in construction type and moisture sensitivity. It is conformal coated rather than molded and has MSL 3 (168 Hours) versus MSL 1 (Unlimited). Use only if conformal coating is specified in the design or required for environmental protection.

Q: What is the significance of the Manufacturer Size Code "A"?

A: The Manufacturer Size Code "A" indicates the physical size classification within the 1206 (3216 Metric) package family. All substitute parts maintain Size Code "A" and are mechanically interchangeable with identical height and footprint dimensions.

Q: Which substitute part has the highest inventory availability?

A: The 293D106X96R3A2TE3 (Vishay Sprague) has the highest inventory availability at 100,300 pieces. This part features 3.4Ohm ESR and is suitable for applications where ESR tolerance is acceptable.

Q: Are there lifetime specifications available for all parts?

A: Lifetime specifications are provided for KEMET parts (T494A106K006AT and T491A106K006AT) at 2000 Hrs @ 125°C. Other manufacturers do not specify lifetime data in the provided documentation. Consult manufacturer datasheets for complete reliability information.

Q: What is the operating temperature range for all substitute parts?

A: All substitute parts maintain the identical operating temperature range of -55°C to 125°C, matching the original 1879062-1 specification.
