Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 1879064-6 are classified into two categories based on electrical and mechanical compatibility:

Upgrade Substitutes: Parts with enhanced electrical specifications that maintain or exceed the original performance envelope. These parts feature higher voltage ratings or improved tolerance specifications while maintaining identical physical package dimensions and capacitance values.

Similar Substitutes: Parts with equivalent electrical specifications matching the original part's capacitance, voltage rating, and tolerance, but with variations in ESR or physical height that remain within acceptable mechanical constraints for the 2312 (6032 Metric) package.

Substitution eligibility is determined by the following parameters:

• Capacitance value: 33 µF (exact match required)
• Package / Case: 2312 (6032 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C to 125°C (minimum requirement)
• Voltage Rating: Equal to or greater than 4 V
• Tolerance: ±20% or better
• Moisture Sensitivity Level: MSL 1 or equivalent

Engineering Selection Recommendations

TPSC336K010R0500 (KYOCERA AVX) is the primary upgrade substitute. This part maintains identical ESR (500 mOhm) and package dimensions while providing a 10 V voltage rating and improved ±10% tolerance. The part is active in production status and ROHS3 compliant, making it suitable for new designs and long-term supply chain continuity.

293D336X0004C2TE3 (Vishay Sprague) is a direct electrical equivalent with matching 4 V rating and ±20% tolerance. This part is active in production and ROHS3 compliant. The elevated ESR of 1.8 Ohm requires circuit-level evaluation to confirm compatibility with the original 500 mOhm specification.

TAJW336M004RNJ (KYOCERA AVX) is a similar substitute with matching electrical specifications (4 V, ±20%, 33 µF). This part features a reduced seated height of 0.059" (1.50 mm) compared to the original 0.106" (2.70 mm), which may provide advantages in space-constrained applications. The ESR of 600 mOhm is marginally higher than the original specification. The part is active in production and ROHS3 compliant.

All three substitute parts are classified as MSL 1 (Unlimited moisture sensitivity), matching the original part's handling requirements.

Frequently Asked Questions (FAQ)

Q: Can TPSC336K010R0500 be used as a direct replacement for 1879064-6?

A: Yes. TPSC336K010R0500 is a direct mechanical and functional substitute. It maintains the same 33 µF capacitance, 2312 (6032 Metric) package, surface mount configuration, and 500 mOhm ESR. The 10 V rating provides enhanced voltage margin over the original 4 V specification, and the ±10% tolerance is superior to the original ±20% tolerance.

Q: What is the significance of ESR differences between substitute parts?

A: Equivalent Series Resistance (ESR) affects capacitor performance in high-frequency applications and ripple current handling. The original part specifies 500 mOhm. TPSC336K010R0500 matches this specification exactly. TAJW336M004RNJ has 600 mOhm ESR (20% higher), and 293D336X0004C2TE3 has 1.8 Ohm ESR (3.6 times higher). Circuit-level analysis is required to determine if elevated ESR values are acceptable for the specific application.

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

A: All substitute parts use the identical 2312 (6032 Metric) package and surface mount configuration. Physical dimensions (0.236" L x 0.126" W) are identical across all parts. Seated height varies: the original is 0.106" (2.70 mm), TPSC336K010R0500 is 0.110" (2.80 mm), 293D336X0004C2TE3 is 0.110" (2.79 mm), and TAJW336M004RNJ is 0.059" (1.50 mm). Height differences must be evaluated against PCB clearance and assembly constraints.

Q: What is the difference between upgrade and similar substitutes?

A: Upgrade substitutes (TPSC336K010R0500) provide enhanced electrical specifications beyond the original part requirements, such as higher voltage ratings or improved tolerances. Similar substitutes (293D336X0004C2TE3, TAJW336M004RNJ) match the original electrical specifications but may have variations in secondary parameters such as ESR or physical height.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All three substitute parts are ROHS3 compliant. The original TE Connectivity 1879064-6 is listed as REACH Unaffected. All substitute parts maintain REACH Unaffected status and ROHS3 compliance, ensuring regulatory compatibility for current manufacturing standards.

Q: What is the moisture sensitivity level (MSL) for these parts?

A: All parts, including the original and all substitutes, are classified as MSL 1 (Unlimited). This classification indicates no moisture sensitivity restrictions and no special storage or handling requirements beyond standard component handling practices.

Q: Why is the original part obsolete?

A: The TE Connectivity 1879064-6 is classified as obsolete, indicating it is no longer in active production. The substitute parts listed are all active in production status, ensuring long-term availability and supply chain reliability for ongoing applications.
