F750J337MDC Equivalent & Substitute Parts

Part Overview

The F750J337MDC is a 330 µF conformal coated tantalum capacitor rated at 6.3 V with ±20% tolerance, manufactured by KYOCERA AVX in the 2917 (7343 Metric) package. This component is designed for surface mount applications requiring general purpose energy storage with conformal coating protection. The part is currently active in production with 1076 units in stock.

Substitute parts are necessary when the original component becomes unavailable, when alternative manufacturers are preferred for supply chain diversification, or when design requirements allow for compatible alternatives with different electrical characteristics such as higher voltage ratings or improved tolerance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the F750J337MDC is determined by the following critical parameters:

Primary Compatibility Criteria:

• Capacitance value: 330 µF (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• ESR: 150 mOhm (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Mounting Type: Surface Mount (exact match required)

Secondary Compatibility Criteria (Allowable Variations):

• Voltage Rating: May be equal to or higher than 6.3 V
• Tolerance: May be ±10% or ±20%
• Type: Conformal Coated or Molded acceptable
• Moisture Sensitivity Level (MSL): May vary

Substitute parts are grouped into two categories: direct voltage-rated equivalents (6.3 V) and higher voltage-rated alternatives (10 V). Higher voltage ratings provide additional design margin and are electrically compatible in applications where the original 6.3 V rating is sufficient.

Parameter Comparison

Engineering Selection Recommendations

Same Voltage Rating (6.3 V) Substitutes:

TPSY337M006R0150 (KYOCERA AVX) is the preferred direct substitute. It maintains identical electrical specifications and RoHS3 compliance. The molded construction replaces the conformal coating, and the reduced height (0.079" vs 0.122") provides additional PCB layout flexibility. MSL rating of 1 (Unlimited) improves moisture handling compared to the original MSL 3 rating.

T494D337M006AH (KEMET) provides equivalent electrical performance at the same voltage rating with matching height. However, this part is RoHS non-compliant, which may restrict use in applications requiring RoHS3 certification.

Higher Voltage Rating (10 V) Substitutes:

TPSD337M010R0150 (KYOCERA AVX) offers increased voltage margin with ±20% tolerance matching the original specification. ROHS3 compliance and MSL 1 rating are maintained. This part is recommended when design requirements allow for higher voltage ratings and when supply availability of 6.3 V variants is constrained.

TPSD337K010R0150 (KYOCERA AVX) provides the same 10 V rating with improved ±10% tolerance and ROHS3 compliance. Higher inventory availability (7908 units) supports supply chain continuity.

T494D337M010AT (KEMET) delivers 10 V rating with ±20% tolerance and ROHS3 compliance. Inventory of 1934 units supports procurement requirements.

TR3D337M010C0150 (Vishay Sprague) offers 10 V rating with ±20% tolerance and ROHS3 compliance. Highest inventory availability (2846 units) among 10 V alternatives.

T494D337K010AT (KEMET) provides 10 V rating with improved ±10% tolerance and ROHS3 compliance, though lower inventory (867 units) may impact availability.

Parts with RoHS non-compliance (T494D337M006AH, T494D337M010AH) should be avoided in applications requiring regulatory compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can I use a 10 V rated capacitor in place of the 6.3 V F750J337MDC?

A: Yes. A higher voltage rating is electrically compatible and provides additional design margin. The capacitor will function correctly in applications designed for 6.3 V operation. Voltage derating improves reliability and extends component lifetime.

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

A: The F750J337MDC uses conformal coating for environmental protection. Molded alternatives (TPSY337M006R0150, TPSD series, T494D series, TR3D series) use a molded epoxy case for protection. Both provide equivalent electrical performance and environmental protection suitable for general purpose applications. Molded construction typically offers improved moisture sensitivity ratings.

Q: Are there physical dimension differences between the main part and substitutes?

A: All substitutes use the 2917 (7343 Metric) package with identical length (0.287") and width (0.169"). Height varies: the original F750J337MDC and most substitutes measure 0.122" maximum seated height. TPSY337M006R0150 has a reduced height of 0.079", which may provide PCB layout advantages in space-constrained designs.

Q: What does MSL rating mean, and why does it vary?

A: Moisture Sensitivity Level (MSL) indicates how long a component can be exposed to ambient conditions before soldering. The original part has MSL 3 (168 hours maximum). Molded substitutes have MSL 1 (Unlimited), meaning they can be stored indefinitely at room conditions without moisture absorption concerns. This improves handling and storage flexibility.

Q: Which substitute offers the best supply availability?

A: TPSD337K010R0150 (KYOCERA AVX) has the highest inventory at 7908 units, followed by TPSD337M010R0150 at 5524 units and TR3D337M010C0150 at 2846 units. All three are ROHS3 compliant and rated at 10 V.

Q: Can I use T494D337M006AH as a direct replacement?

A: T494D337M006AH matches the 6.3 V rating and ±20% tolerance with identical ESR and package. However, it is RoHS non-compliant. Use only if your application does not require RoHS3 certification.

Q: What tolerance should I select: ±10% or ±20%?

A: The original F750J337MDC uses ±20% tolerance. Substitutes with ±10% tolerance (TPSD337K010R0150, T494D337K010AT) provide tighter capacitance control if your circuit design requires it. Both are electrically compatible; selection depends on circuit performance requirements.
