Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1879064-5 is determined by the following critical parameters:

Primary Substitution Criteria:

• Capacitance: 33 µF (exact match required)
• Tolerance: ±10% (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 (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Secondary Compatibility Parameters:

• Voltage - Rated: 4 V or higher (equal or greater voltage rating acceptable)
• ESR (Equivalent Series Resistance): 500 mOhm or lower (lower ESR acceptable)
• Type: Molded Tantalum (exact match required)

Substitute parts are classified into two categories:

Upgrade Substitutes: Parts with identical electrical specifications except for higher voltage rating (10 V vs. 4 V). These provide enhanced voltage margin and are direct functional replacements.

Similar Substitutes: Parts with identical voltage rating (4 V) and all primary parameters matching, with variations in ESR or physical height within acceptable tolerances.

Engineering Selection Recommendations

KYOCERA AVX TPSC336K010R0500 (Upgrade Substitute)

This part is the primary upgrade substitute for the obsolete TE Connectivity 1879064-5. The TPSC336K010R0500 maintains identical capacitance, tolerance, package, and ESR specifications while providing a higher voltage rating of 10 V. The part is active in production status and carries ROHS3 compliance certification. The increased voltage rating provides additional design margin without affecting circuit performance in 4 V applications. Inventory availability is confirmed at 878 pieces.

Vishay Sprague 293D336X9004C2TE3 (Similar Substitute)

This part provides direct electrical equivalence at the 4 V rating with identical capacitance and tolerance. The TANTAMOUNT™ series part is active in production and ROHS3 compliant. The ESR specification of 1.8 Ohm is higher than the original 500 mOhm, which may impact performance in applications sensitive to series resistance. Physical height is 0.110" (2.79 mm), within acceptable tolerance of the original 0.106" (2.70 mm). Inventory availability is confirmed at 826 pieces.

KYOCERA AVX TAJW336K004RNJ (Similar Substitute)

This part matches the original 4 V voltage rating and all primary electrical parameters. The TAJ series part is active in production and ROHS3 compliant. The ESR specification of 600 mOhm is slightly higher than the original 500 mOhm. The seated height of 0.059" (1.50 mm) is significantly lower than the original 0.106" (2.70 mm), which may provide advantages in space-constrained applications. Inventory availability is confirmed at 935 pieces.

All three substitute parts satisfy the mandatory substitution criteria of capacitance, tolerance, package, mounting type, operating temperature range, and moisture sensitivity level. Selection among these options depends on specific application requirements regarding voltage margin, ESR sensitivity, and physical height constraints.

Frequently Asked Questions (FAQ)

Q: Can the KYOCERA AVX TPSC336K010R0500 (10 V rated) be used in place of the TE Connectivity 1879064-5 (4 V rated)?

A: Yes. The TPSC336K010R0500 is a direct functional substitute. A higher voltage rating provides additional design margin and does not degrade performance in circuits designed for 4 V operation. All other electrical and mechanical parameters are identical.

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

A: ESR (Equivalent Series Resistance) affects impedance characteristics and heat dissipation. The original part specifies 500 mOhm. The Vishay Sprague 293D336X9004C2TE3 has 1.8 Ohm ESR, which is significantly higher and may impact performance in applications requiring low impedance. The KYOCERA AVX TAJW336K004RNJ has 600 mOhm ESR, which is marginally higher and generally acceptable for most applications.

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

A: All substitute parts share the identical 2312 (6032 Metric) package and footprint dimensions of 0.236" L x 0.126" W (6.00 mm x 3.20 mm). Physical height varies slightly: the original is 0.106" (2.70 mm), while substitutes range from 0.059" to 0.110" (1.50 mm to 2.80 mm). These height variations are within standard PCB assembly tolerances and do not affect placement compatibility.

Q: Do all substitute parts meet current compliance requirements?

A: The KYOCERA AVX TPSC336K010R0500, Vishay Sprague 293D336X9004C2TE3, and KYOCERA AVX TAJW336K004RNJ are all ROHS3 compliant and REACH unaffected. The original TE Connectivity 1879064-5 does not specify RoHS status but is REACH unaffected. All parts carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the product status significance of the substitute parts?

A: All three substitute parts are classified as active in production status, ensuring long-term availability and supply chain stability. The original TE Connectivity 1879064-5 is obsolete, making substitution necessary for new designs and ongoing procurement.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the application does not have specific ESR or height constraints. The KYOCERA AVX TPSC336K010R0500 is the preferred substitute due to identical ESR and higher voltage rating. The other two substitutes are functionally equivalent but with noted ESR and height variations that should be evaluated against specific circuit requirements.
