Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 7-1879062-3 is determined by strict equivalence across the following parameters: capacitance value (0.22 µF), voltage rating (35 V), tolerance (±10%), package type (1206 / 3216 Metric), mounting configuration (surface mount), and operating temperature range (-55°C ~ 125°C).

The substitute parts are grouped into two categories based on ESR specification:

Direct Equivalents (6 Ohm ESR): Parts with identical ESR characteristics to the original component. These provide the closest electrical performance match.

Similar Equivalents (15-18 Ohm ESR): Parts that meet all core electrical and mechanical parameters but with higher ESR values. These parts are functionally compatible but exhibit different impedance characteristics at operating frequencies.

All substitute parts maintain the same physical dimensions, mounting footprint, and environmental specifications as the original component.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical ESR Performance):

Select T494A224K035AT (KEMET) or TPSA224K035R6000 (KYOCERA AVX) when ESR specification of 6 Ohm is critical to circuit performance. Both parts are active products with ROHS3 compliance and maintain identical electrical characteristics to the original TE Connectivity component. T494A224K035AT is available in Tape & Reel packaging with 2000 Hrs @ 125°C lifetime rating. TPSA224K035R6000 is also available in Tape & Reel packaging.

For General Purpose Applications:

T491A224K035AT (KEMET) or TAJA224K035RNJ (KYOCERA AVX) are suitable alternatives when circuit design tolerates higher ESR values (18 Ohm). Both are active products with ROHS3 compliance. TAJA224K035RNJ offers the highest inventory availability (20,400 pcs) among all substitutes. T491A224K035AT includes 2000 Hrs @ 125°C lifetime specification.

For Cost-Optimized Selection:

293D224X9035A2TE3 (Vishay Sprague) provides an alternative with 15 Ohm ESR and the highest inventory level (6,524 pcs). This part is active and ROHS3 compliant, suitable for applications where moderate ESR variance is acceptable.

All substitute parts share identical operating temperature range (-55°C ~ 125°C), moisture sensitivity level (MSL 1), and physical dimensions with the original component, ensuring PCB footprint compatibility and environmental performance equivalence.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with higher ESR (15-18 Ohm) instead of the original 6 Ohm specification?

A: Higher ESR values affect circuit impedance and frequency response characteristics. Substitution with 15-18 Ohm ESR parts is permissible only if circuit design specifications allow for this variance. Review your circuit's frequency response requirements and ripple current handling before selecting higher ESR alternatives.

Q: Are all substitute parts compatible with the original PCB footprint?

A: Yes. All substitute parts use the 1206 (3216 Metric) package with identical physical dimensions (0.126" L x 0.063" W, 3.20mm x 1.60mm). However, TAJS224K035RNJ has a different seated height (0.047" / 1.20mm) compared to the original (0.071" / 1.80mm). Verify clearance requirements for your specific PCB assembly before selecting this part.

Q: What is the difference between the TPSA224K035R6000 and TPSA224K035Y6000 variants?

A: Both parts are from KYOCERA AVX's TPS series with identical electrical specifications (0.22 µF, 35 V, 6 Ohm ESR). The difference lies in the internal designation code (R6000 vs. Y6000). Both are active products with ROHS3 compliance and equivalent performance. Selection between these variants depends on your supplier's availability and internal part numbering systems.

Q: Which substitute offers the best long-term availability?

A: TAJA224K035RNJ (KYOCERA AVX) has the highest current inventory (20,400 pcs) and is an active product, indicating strong manufacturer support. T494A224K035AT (KEMET) and TPSA224K035R6000 (KYOCERA AVX) also have substantial inventory levels (3,008 and 2,789 pcs respectively) and active product status.

Q: Do all substitutes meet RoHS compliance requirements?

A: Yes. All substitute parts are ROHS3 compliant. The original TE Connectivity 7-1879062-3 does not specify RoHS status, but all active alternatives meet current RoHS3 standards, ensuring compliance with modern procurement and environmental regulations.

Q: What is the significance of the "Lifetime @ Temp." specification?

A: The 2000 Hrs @ 125°C rating provided for T494A224K035AT and T491A224K035AT indicates the component's expected operational life under maximum temperature stress conditions. This specification is relevant for high-reliability applications. Other substitutes do not provide this specification in the available data.
