Equivalent & Substitute Parts for 1879063-7

Part Overview

The TE Connectivity 1879063-7 is a 22 µF molded tantalum capacitor rated at 4 V with 600 mOhm equivalent series resistance in a 1411 (3528 Metric) surface mount package. This component is classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility. Substitute parts must preserve the 22 µF capacitance, ±10% tolerance, 600 mOhm ESR, 1411 package form factor, and surface mount mounting type while accommodating higher voltage ratings where applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1879063-7 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters (Must Match Exactly):

• Capacitance: 22 µF
• Tolerance: ±10%
• Type: Molded Tantalum
• ESR: 600 mOhm
• Package / Case: 1411 (3528 Metric)
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C ~ 125°C
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Voltage - Rated: Substitute parts may have equal or higher voltage ratings than the original 4 V specification. Higher voltage ratings provide design margin and are electrically compatible in applications requiring 4 V operation.

All substitute parts listed maintain identical capacitance, tolerance, ESR, package dimensions, and thermal operating range. Voltage ratings range from 6.3 V to 20 V, all exceeding the original 4 V specification and therefore suitable for direct replacement in circuits designed for 4 V operation.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The original part 1879063-7 carries an obsolete status, making substitute selection necessary for new designs and ongoing production. All listed substitute parts maintain active product status, ensuring continued availability and manufacturer support.

Compliance and Certification: All substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The original part does not specify RoHS compliance status. Substitute parts from both Vishay Sprague and KEMET provide equivalent electrical performance with modern compliance certifications.

Voltage Rating Selection:

• 593D226X96R3B2TE3 and TR3B226K6R3C0600 (6.3 V): Minimal voltage margin above the original 4 V specification. Suitable for applications with stable 4 V supply voltages.
• T495B226K016ATE600 and TR3B226K016C0600 (16 V): Moderate voltage margin. Provides design flexibility for circuits with potential voltage transients or future design modifications.
• TR3B226K020C0600 (20 V): Maximum voltage margin. Recommended for applications requiring enhanced protection against voltage spikes or supply variations.

Manufacturer Availability: KEMET T495B226K016ATE600 offers the highest inventory level (20,509 pcs), providing supply chain reliability. Vishay Sprague alternatives provide multiple voltage options with active inventory levels ranging from 1,080 to 8,780 pcs.

Frequently Asked Questions (FAQ)

Q: Can the 1879063-7 be directly replaced with a higher voltage-rated substitute? A: Yes. All substitute parts maintain identical capacitance (22 µF), tolerance (±10%), ESR (600 mOhm), package dimensions (1411/3528 Metric), and thermal operating range (-55°C to 125°C). Higher voltage ratings are electrically compatible with circuits designed for 4 V operation and provide additional design margin.

Q: What is the difference between the Vishay Sprague and KEMET substitute options? A: Both manufacturers provide 22 µF molded tantalum capacitors in the 1411 package with 600 mOhm ESR and ±10% tolerance. KEMET T495B226K016ATE600 offers the highest inventory availability and specifies 2000 Hrs lifetime at 85°C. Vishay Sprague options provide multiple voltage ratings (6.3 V, 16 V, 20 V) with TANTAMOUNT™ series designation.

Q: Are the physical dimensions identical across all substitute parts? A: Yes. All substitute parts share the same 1411 (3528 Metric) package with dimensions of 0.138" L x 0.110" W (3.50mm x 2.80mm). Maximum seated height is 0.083" (2.10mm to 2.11mm), ensuring compatibility with existing PCB layouts and assembly processes.

Q: Which substitute part should be selected for maximum design margin? A: TR3B226K020C0600 provides the highest voltage rating at 20 V, offering maximum protection against voltage transients and supply variations. This part is suitable for applications requiring enhanced reliability in variable voltage environments.

Q: Are all substitute parts RoHS compliant? A: Yes. All substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards. The original 1879063-7 does not specify RoHS compliance status.

Q: What is the moisture sensitivity level for substitute parts? A: All substitute parts maintain MSL 1 (Unlimited), identical to the original part. This classification indicates no moisture sensitivity restrictions and no special handling requirements during storage or assembly.
