Engineering Selection Recommendations

Primary Selection Criteria:

All substitute parts listed are classified as Active product status, ensuring long-term availability and manufacturing continuity. The original TE Connectivity 1879062-6 is obsolete and should be replaced in new designs and production runs.

Compliance and Certifications:

All substitute parts from KYOCERA AVX and Vishay Sprague are ROHS3 compliant, meeting current environmental and regulatory requirements. All parts maintain REACH Unaffected status and EAR99 ECCN classification, consistent with the original component.

Voltage Rating Selection:

For direct functional replacement in applications operating at 6.3 V or below, select substitute parts with voltage ratings of 10 V or higher. The 293D225X0010A2TE3 (10 V rating) provides the minimum voltage margin above the original 6.3 V specification. Higher voltage ratings (16 V, 20 V, 25 V) provide additional design margin and are suitable for all applications originally designed for the 1879062-6.

Tolerance and ESR Considerations:

Substitute parts with ±10% or ±5% tolerance offer improved capacitance accuracy compared to the original ±20% tolerance. Parts with lower ESR values (5.9 Ohm versus 6 Ohm) provide superior high-frequency performance. The KYOCERA AVX F931E225MAA and Vishay Sprague 293D225X0020A2TE3 maintain identical ±20% tolerance and comparable ESR characteristics to the original part while offering active status and higher voltage ratings.

Temperature Range:

The Vishay Sprague TH3A225K020D5900 extends the operating temperature range to -55°C ~ 150°C, providing enhanced thermal performance for demanding applications. All other substitute parts maintain the original -55°C ~ 125°C range.

Frequently Asked Questions (FAQ)

Q: Can the 1879062-6 be directly replaced with any of the listed substitute parts?

A: Yes. All substitute parts maintain identical 2.2 µF capacitance, 1206 (3216 Metric) package form factor, and surface mount configuration. Electrical and mechanical compatibility is confirmed for all listed substitutes.

Q: What is the significance of voltage rating differences between the original part and substitutes?

A: The original 1879062-6 is rated at 6.3 V. All substitute parts are rated at 10 V or higher, providing equal or greater voltage margin. Higher voltage ratings do not negatively impact circuit performance in applications operating below the rated voltage. Selection of substitute parts with voltage ratings exceeding the circuit operating voltage is standard engineering practice.

Q: How do tolerance differences affect part selection?

A: The original part specifies ±20% tolerance. Substitute parts with ±20%, ±10%, or ±5% tolerance are all acceptable replacements. Tighter tolerance specifications (±10% or ±5%) provide improved capacitance accuracy and may enhance circuit performance in precision applications. No circuit redesign is required when upgrading to tighter tolerance parts.

Q: What does ESR (Equivalent Series Resistance) represent, and why does it vary between parts?

A: ESR is the internal resistance of the capacitor at specified frequency. Lower ESR values indicate superior high-frequency performance and reduced power dissipation. Substitute parts with ESR values of 5.9 Ohm or 6.3 Ohm are functionally equivalent to the original 6 Ohm specification. ESR differences of this magnitude do not require circuit redesign.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts from KYOCERA AVX and Vishay Sprague are ROHS3 compliant. The original TE Connectivity 1879062-6 RoHS status is not specified in available documentation.

Q: Which substitute part provides the best overall performance upgrade?

A: The Vishay Sprague TH3A225K020D5900 offers the broadest performance envelope with a 20 V voltage rating, ±10% tolerance, 5.9 Ohm ESR, and extended operating temperature range to 150°C. The KYOCERA AVX F931E225MAA provides a direct functional equivalent with identical ±20% tolerance, 25 V voltage rating, and active product status with high inventory availability.

Q: Can substitute parts with lower voltage ratings (10 V) be used in place of the original 6.3 V part?

A: The 293D225X0010A2TE3 (10 V rating) provides adequate voltage margin for applications operating at or below 6.3 V. However, substitute parts with higher voltage ratings (16 V, 20 V, or 25 V) are preferred to maximize design safety margin and component reliability.

Q: What packaging options are available for substitute parts?

A: All substitute parts are supplied in Tape & Reel (TR) packaging for automated assembly. The Vishay Sprague 293D225X9016A2TE3 is also available in Cut Tape (CT) & Digi-Reel® packaging for lower-volume applications.

Q: Are there any thermal performance differences between substitute parts?

A: The Vishay Sprague TH3A225K020D5900 supports operating temperatures to 150°C, compared to 125°C for all other parts. This extended range is beneficial for high-temperature applications. All parts maintain identical -55°C minimum operating temperature.
