Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the F751A337MDC are qualified based on the following criteria:

Electrical Parameters (Critical):

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 10 V (exact match required)
• ESR: 150 mOhm (exact match required)
• Tolerance: ±10% or ±20% (both acceptable; ±10% provides tighter tolerance)

Mechanical Parameters (Critical):

• Package / Case: 2917 (7343 Metric) (exact match required)
• Size / Dimension: 0.287" L x 0.169" W (7.30 mm x 4.30 mm) (exact match required)
• Height - Seated (Max): 0.122" (3.10 mm) (exact match required)
• Mounting Type: Surface Mount (exact match required)

Environmental & Compliance Parameters:

• Operating Temperature: -55°C ~ 125°C (exact match required)
• RoHS Status: ROHS3 Compliant (preferred)
• Moisture Sensitivity Level (MSL): 1 or 3 (both acceptable; MSL 1 preferred for unlimited storage)

Substitute parts may differ in construction type (Conformal Coated vs. Molded) and manufacturer, provided all electrical and mechanical parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (ROHS3 Compliant, MSL 1):

TPSD337M010R0150 and TPSD337K010R0150 (KYOCERA AVX, TPS series) are direct functional equivalents with identical electrical and mechanical specifications. Both feature MSL 1 rating (unlimited storage) compared to the original part's MSL 3 (168 hours), providing superior moisture handling characteristics. TPSD337K010R0150 offers ±10% tolerance for applications requiring tighter capacitance control.

T494D337M010AT (KEMET, T494 series) is a ROHS3 compliant alternative with MSL 1 rating and documented lifetime specification of 2000 hours at 125°C. This part is suitable for applications where extended thermal performance data is required.

TR3D337M010C0150 (Vishay Sprague, TR3 series) is a ROHS3 compliant molded tantalum capacitor with MSL 1 rating and equivalent electrical performance.

Secondary Substitute (Compliance Consideration):

T494D337M010AH (KEMET, T494 series) meets all electrical and mechanical requirements but is RoHS non-compliant. This part is suitable only for applications where RoHS compliance is not mandated.

T494D337K010AT (KEMET, T494 series) offers ±10% tolerance with ROHS3 compliance and MSL 1 rating, suitable for precision applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute the F751A337MDC with a molded tantalum capacitor instead of conformal coated?

A: Yes. The substitute parts listed (TPSD337 series, T494D series, TR3D series) are molded tantalum capacitors that meet all electrical specifications (330 µF, 10 V, 150 mOhm ESR) and mechanical requirements (2917 package, identical dimensions). Construction type difference does not affect functional compatibility when electrical and mechanical parameters are identical.

Q: What is the difference between ±10% and ±20% tolerance parts?

A: Both tolerances are acceptable substitutes. ±10% tolerance (TPSD337K010R0150, T494D337K010AT) provides tighter capacitance control within ±10% of the nominal 330 µF value. ±20% tolerance parts (TPSD337M010R0150, T494D337M010AT, TR3D337M010C0150) allow capacitance variation within ±20%. Selection depends on circuit requirements for capacitance accuracy.

Q: Why do some substitute parts have MSL 1 while the original has MSL 3?

A: MSL (Moisture Sensitivity Level) indicates moisture absorption limits during storage. MSL 1 (Unlimited) allows indefinite storage without baking, while MSL 3 (168 hours) requires baking after 168 hours of exposure to ambient humidity. Substitute parts with MSL 1 offer superior storage flexibility with no moisture-related handling restrictions.

Q: Is T494D337M010AH suitable for my application?

A: T494D337M010AH meets all electrical and mechanical specifications but is RoHS non-compliant. Use this part only if your application does not require RoHS3 compliance. For RoHS3 compliant designs, select T494D337M010AT instead.

Q: Can I use these substitutes in high-temperature applications?

A: All listed substitutes operate across the same temperature range (-55°C ~ 125°C) as the original part. T494D series parts provide documented lifetime specification of 2000 hours at 125°C, suitable for extended thermal stress applications.

Q: Are there any package or footprint differences between these parts?

A: No. All substitute parts use the identical 2917 (7343 Metric) package with dimensions 7.30 mm x 4.30 mm and maximum seated height of 3.10 mm. PCB footprints and assembly processes remain unchanged.
