Substitute Part Grouping Explanation

Substitution of the TE Connectivity 5-1879063-6 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance value: 4.7 µF (exact match required)
• Voltage rating: 25 V (minimum, equal or higher acceptable)
• Type: Molded tantalum (material and construction type)
• ESR: 1 Ohm (equivalent series resistance specification)
• Operating temperature range: -55°C to 125°C (minimum coverage required)

Mechanical Equivalence Requirements:

• Package / Case: 1411 (3528 Metric) (exact match required for PCB compatibility)
• Mounting type: Surface mount (exact match required)
• Moisture sensitivity level: 1 (Unlimited) (equal or better required)

Compliance Equivalence:

• REACH Status: REACH Unaffected (maintained across substitutes)
• ECCN: EAR99 (maintained across substitutes)

The substitute part TR3B475K025C1000 meets all electrical, mechanical, and compliance requirements. The tolerance specification of ±10% on the substitute part represents an improvement over the ±20% tolerance of the original part, providing tighter capacitance control while maintaining full functional compatibility.

Engineering Selection Recommendations

The Vishay Sprague TR3B475K025C1000 is the direct substitute for the obsolete TE Connectivity 5-1879063-6. Selection of this substitute is based on the following engineering factors:

Product Status: The original part is classified as obsolete, making the active-status substitute necessary for ongoing component availability and supply chain continuity.

Electrical Specifications: The substitute maintains identical capacitance (4.7 µF), voltage rating (25 V), ESR (1 Ohm), and operating temperature range (-55°C to 125°C). The improved tolerance specification (±10% versus ±20%) provides enhanced capacitance accuracy without introducing any compatibility concerns.

Mechanical Compatibility: The substitute shares identical package dimensions (1411 / 3528 Metric), footprint (0.138" L x 0.110" W), and height specifications (0.083" maximum seated height), ensuring direct PCB layout compatibility without redesign requirements.

Compliance and Certifications: Both parts maintain equivalent REACH Status (REACH Unaffected), ECCN classification (EAR99), and moisture sensitivity level (MSL 1 - Unlimited), ensuring regulatory and environmental compliance equivalence.

Packaging Availability: The substitute is available in Tape & Reel (TR) packaging format with confirmed inventory stock, supporting both prototype and production-volume requirements.

Frequently Asked Questions (FAQ)

Q: Can the Vishay Sprague TR3B475K025C1000 be used as a direct replacement for the TE Connectivity 5-1879063-6 without PCB modifications?

A: Yes. Both parts share identical package specifications (1411 / 3528 Metric), footprint dimensions (0.138" L x 0.110" W), and maximum seated height (0.083"). No PCB layout or design changes are required for substitution.

Q: What is the significance of the tolerance difference between the original part (±20%) and the substitute (±10%)?

A: The substitute provides tighter capacitance tolerance, meaning the actual capacitance value will be closer to the nominal 4.7 µF specification. This represents an improvement in component precision and is fully compatible with circuit designs that accepted the original ±20% tolerance specification.

Q: Are the electrical performance characteristics identical between these two parts?

A: Yes. Both parts specify 4.7 µF capacitance, 25 V voltage rating, 1 Ohm ESR, and -55°C to 125°C operating temperature range. These parameters are electrically equivalent and ensure identical circuit performance.

Q: What is the moisture sensitivity level (MSL) for both parts, and what does this mean for handling?

A: Both parts are classified as MSL 1 (Unlimited), indicating unlimited shelf life without moisture absorption concerns. Standard handling procedures for surface mount components apply, but these parts do not require special moisture-controlled storage or baking procedures prior to reflow soldering.

Q: Are there any compliance or regulatory differences between the original and substitute parts?

A: No. Both parts maintain identical REACH Status (REACH Unaffected), ECCN classification (EAR99), and HTSUS codes (8532.21.0050), ensuring equivalent regulatory and trade compliance.

Q: What packaging format is the substitute available in?

A: The Vishay Sprague TR3B475K025C1000 is available in Tape & Reel (TR) packaging format, suitable for automated assembly processes and high-volume production applications.

Q: Is the substitute part currently in active production?

A: Yes. The Vishay Sprague TR3B475K025C1000 is classified as active product status, ensuring long-term availability and supply chain reliability compared to the obsolete original part.
