TE Connectivity 1879064-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1879064-1 is a 100 µF molded tantalum capacitor rated at 4 V with ±10% tolerance, housed in a 2312 (6032 Metric) surface mount package. This component is classified as obsolete product status. The TYTR series capacitor features 200 mOhm equivalent series resistance and operates across a temperature range of -55°C to 125°C. Due to its obsolete status, equivalent and substitute parts from active manufacturers are necessary for ongoing design support, production continuity, and long-term component availability.

Primary Substitution Criteria:

Capacitance: 100 µF (exact match required)
Tolerance: ±10% (exact match required)
Type: Molded Tantalum (exact match required)
ESR: 200 mOhm (exact match required)
Operating Temperature: -55°C to 125°C (exact match required)
Mounting Type: Surface Mount (exact match required)
Package / Case: 2312 (6032 Metric) (exact match required)
Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Voltage Rating Consideration: Substitute parts are grouped into two categories based on voltage rating:

Upgrade Substitutes (Higher Voltage Rating): Parts rated at 10 V or 16 V provide voltage derating capability while maintaining all other electrical and mechanical parameters. These parts are direct functional replacements with enhanced voltage margin.
Similar Parts (Same Voltage Rating): Parts rated at 4 V with identical voltage specification but differing ESR values (225 mOhm, 800 mOhm) or parts with alternative voltage ratings at 4 V are classified as similar alternatives.

All substitute parts listed maintain identical physical dimensions, package specifications, and operating temperature ranges as the original component.

Engineering Selection Recommendations

Upgrade Substitute Selection:

The upgrade substitute parts 593D107X9010C2TE3 (Vishay Sprague), T494C107K010AT (KEMET), TPSC107K010R0200 (KYOCERA AVX), and TR3C107K010C0200 (Vishay Sprague) are all rated at 10 V and maintain identical electrical specifications (100 µF, ±10%, 200 mOhm ESR) and mechanical compatibility with the original 1879064-1. All four parts carry active product status and ROHS3 compliance certification. These parts provide voltage derating capability for applications originally designed for 4 V operation.

The upgrade substitute TPSC107K016R0200 (KYOCERA AVX) is rated at 16 V and provides the highest voltage margin while maintaining all other electrical and mechanical parameters. This part carries active product status and ROHS3 compliance certification.

Similar Part Selection:

The similar part TR3C107K004C0225 (Vishay Sprague) maintains the original 4 V voltage rating with identical capacitance and tolerance specifications. However, the ESR is specified at 225 mOhm, which differs from the original 200 mOhm specification. This part carries active product status and ROHS3 compliance certification.

The similar part 293D107X9004C2TE3 (Vishay Sprague) maintains the original 4 V voltage rating with identical capacitance and tolerance specifications. However, the ESR is specified at 800 mOhm, which significantly differs from the original 200 mOhm specification. This part carries active product status and ROHS3 compliance certification.

All substitute and similar parts are manufactured by established suppliers with active product status, ensuring long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the upgrade substitute parts with 10 V or 16 V ratings be used in place of the original 4 V rated component?

A: Yes. The upgrade substitute parts with higher voltage ratings (10 V and 16 V) are electrically and mechanically compatible with the original 1879064-1. Higher voltage ratings provide additional voltage margin and do not negatively impact circuit performance in applications originally designed for 4 V operation. All upgrade substitutes maintain identical capacitance (100 µF), tolerance (±10%), ESR (200 mOhm), and package specifications (2312/6032 Metric).

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

A: Upgrade substitutes (593D107X9010C2TE3, T494C107K010AT, TPSC107K010R0200, TPSC107K016R0200, TR3C107K010C0200) maintain the original 200 mOhm ESR specification while providing higher voltage ratings. Similar parts (293D107X9004C2TE3, TR3C107K004C0225) maintain the original 4 V voltage rating but feature different ESR values (800 mOhm and 225 mOhm respectively), which may affect circuit performance in applications sensitive to equivalent series resistance.

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

A: Yes. All substitute and similar parts are housed in the 2312 (6032 Metric) surface mount package with identical footprint dimensions (0.236" L x 0.126" W / 6.00 mm x 3.20 mm). Maximum seated heights range from 0.106" to 0.110" (2.70 mm to 2.80 mm), which falls within standard PCB assembly tolerances for surface mount components.

Q: What compliance certifications do the substitute parts carry?

A: All upgrade substitute parts and similar parts carry ROHS3 compliance certification. The original 1879064-1 does not specify RoHS status. All parts are REACH Unaffected and carry EAR99 ECCN classification with HTSUS code 8532.21.0050.

Q: Which substitute part should be selected for maximum design margin?

A: The TPSC107K016R0200 (KYOCERA AVX) provides the highest voltage rating at 16 V while maintaining all other electrical and mechanical specifications identical to the original component. This part offers the greatest voltage derating capability for applications requiring enhanced reliability margins.

Q: Are there inventory considerations when selecting a substitute part?

A: Inventory availability varies among substitute parts. Current stock levels are: TR3C107K010C0200 (10,300 pcs), 593D107X9010C2TE3 (4,553 pcs), TPSC107K010R0200 (2,700 pcs), T494C107K010AT (1,660 pcs), TPSC107K016R0200 (1,133 pcs), 293D107X9004C2TE3 (816 pcs), and TR3C107K004C0225 (812 pcs). Inventory levels should be verified with suppliers for current availability.
