F751A337KDC Equivalent & Substitute Parts

Part Overview

The F751A337KDC is a 330 µF conformal coated tantalum capacitor rated at 10 V, manufactured by KYOCERA AVX in the 2917 (7343 Metric) package. This component is designed for general-purpose surface mount applications requiring stable capacitance and low equivalent series resistance (ESR) of 150 mOhm across an operating temperature range of -55°C to 125°C. The part is currently active in production with ROHS3 compliance and MSL 3 rating. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and rated parameters.

Substitute Part Grouping Explanation

Substitute parts for the F751A337KDC are qualified based on the following criteria:

• Identical capacitance value: 330 µF
• Identical voltage rating: 10 V
• Identical tolerance: ±10%
• Identical ESR specification: 150 mOhm
• Identical package footprint: 2917 (7343 Metric)
• Identical mounting type: Surface Mount
• Identical physical dimensions and height
• Identical operating temperature range: -55°C to 125°C
• ROHS3 compliance maintained
• Active product status

The primary distinction between the main part and substitutes is the capacitor type: the F751A337KDC features conformal coating, while the identified substitutes utilize molded construction. Both construction types meet the specified electrical and mechanical parameters for direct substitution in applications where the coating type does not impose additional design constraints.

Parameter Comparison

Engineering Selection Recommendations

All three parts meet the core electrical and mechanical requirements for direct substitution. Selection between the main part and substitutes should be based on the following factors:

TPSD337K010R0150 (KYOCERA AVX): This substitute maintains the same manufacturer as the main part, ensuring consistency in manufacturing processes and quality standards. The molded construction offers improved moisture sensitivity performance (MSL 1 versus MSL 3), providing greater flexibility in storage and handling conditions. This part is recommended when supply continuity with the original manufacturer is prioritized or when enhanced moisture tolerance is beneficial.

T494D337K010AT (KEMET): This substitute provides cross-manufacturer compatibility while maintaining all critical electrical specifications. The molded construction and MSL 1 rating offer the same moisture handling advantages as the KYOCERA AVX molded alternative. This part is recommended when multi-source qualification is required or when KEMET components are preferred within the supply chain.

The conformal coating on the F751A337KDC may be specified for applications requiring enhanced protection against environmental contaminants or corrosive atmospheres. In such cases, the main part should be retained. For general-purpose applications without specific coating requirements, the molded substitutes offer equivalent performance with improved moisture characteristics.

Frequently Asked Questions (FAQ)

Q: Can TPSD337K010R0150 and T494D337K010AT be used interchangeably with F751A337KDC?

A: Yes, both parts are direct electrical and mechanical equivalents. All three components share identical capacitance (330 µF), voltage rating (10 V), tolerance (±10%), ESR (150 mOhm), package footprint (2917), and operating temperature range (-55°C to 125°C). The primary difference is construction type: conformal coated versus molded. Selection depends on application-specific requirements for coating protection.

Q: What is the difference between conformal coated and molded tantalum capacitors?

A: Conformal coating provides a protective layer applied over the component surface, offering enhanced protection in harsh environments. Molded construction encases the component in a protective resin body. Both achieve the same electrical performance and compliance certifications. Molded parts typically offer superior moisture sensitivity ratings (MSL 1 versus MSL 3).

Q: Are there any compatibility issues when substituting these parts on a PCB?

A: No. All three parts use identical 2917 (7343 Metric) package footprints with matching physical dimensions (0.287" L x 0.169" W, 3.10 mm max height) and surface mount mounting type. PCB layouts and reflow profiles require no modification.

Q: Which substitute should I choose for high-moisture environments?

A: Both TPSD337K010R0150 and T494D337K010AT carry MSL 1 ratings (unlimited moisture sensitivity level), compared to MSL 3 for the F751A337KDC. Either molded substitute is suitable for applications with extended exposure to humid conditions or where storage without desiccant packaging is required.

Q: Do all three parts meet RoHS compliance?

A: Yes. F751A337KDC, TPSD337K010R0150, and T494D337K010AT are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the lifetime specification for these parts?

A: The F751A337KDC and TPSD337K010R0150 do not specify a rated lifetime at temperature. The T494D337K010AT specifies 2000 hours at 125°C. For applications requiring specific lifetime guarantees, consult the manufacturer's detailed reliability data.
