KEMET T520V337M004ASE009 Equivalent & Substitute Parts

Part Overview

The KEMET T520V337M004ASE009 is a 330 µF molded tantalum polymer capacitor rated at 4 V with a 2917 (7343 Metric) package footprint. This component is classified as obsolete, indicating discontinuation from active manufacturing. The part operates across a temperature range of -55°C to 105°C with a specified lifetime of 2000 hours at 105°C. Due to its obsolete status, equivalent substitute parts from the same manufacturer series are necessary for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution of the obsolete T520V337M004ASE009 is based on strict electrical and mechanical parameter matching within the KEMET KO-CAP® T520 series. The following criteria determine valid equivalency:

Critical Matching Parameters:

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 4 V (exact match required)
• ESR: 9 mOhm @ 100 kHz (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Operating Temperature Range: -55°C to 105°C (exact match required)
• Tolerance: ±20% (exact match required)

Substitute Classification:

Direct Manufacturer Equivalent: T520V337M004ATE009 shares identical electrical specifications and mechanical dimensions. The primary distinction is packaging format (Tape & Reel versus bulk) and active product status.

Parametric Equivalents: T520V337M004ATE0097652 and T520V337M004ATE0098000 are functionally identical to the main part across all specified electrical and mechanical parameters. These variants represent different manufacturing lot codes or distribution channels while maintaining complete parameter compatibility.

Engineering Selection Recommendations

Primary Recommendation: T520V337M004ATE009

This part is the direct active equivalent of the obsolete T520V337M004ASE009. Selection of T520V337M004ATE009 is justified by:

• Active product status ensuring long-term availability and supply chain stability
• ROHS3 compliance meeting current regulatory requirements
• Identical electrical and mechanical specifications to the original part
• Tape & Reel packaging suitable for automated assembly processes

Secondary Recommendations: T520V337M004ATE0097652 and T520V337M004ATE0098000

These parts provide parametric equivalency with identical performance characteristics. Selection between these variants and T520V337M004ATE009 depends on procurement channel availability and inventory allocation. All three active substitutes are functionally interchangeable within the specified application parameters.

Compliance Consideration:

The original T520V337M004ASE009 is RoHS non-compliant. All recommended substitutes (T520V337M004ATE009, T520V337M004ATE0097652, T520V337M004ATE0098000) are ROHS3 compliant, aligning with current environmental and regulatory standards for electronic component manufacturing and distribution.

Frequently Asked Questions (FAQ)

Q: Can T520V337M004ATE009 be used as a direct replacement for T520V337M004ASE009?

A: Yes. T520V337M004ATE009 is electrically and mechanically identical to T520V337M004ASE009 across all specified parameters including capacitance, voltage rating, ESR, package dimensions, and operating temperature range. The primary differences are product status (active versus obsolete) and packaging format (Tape & Reel versus bulk).

Q: What is the difference between T520V337M004ATE009, T520V337M004ATE0097652, and T520V337M004ATE0098000?

A: All three parts are parametrically equivalent with identical electrical and mechanical specifications. The suffix variations (ATE009, ATE0097652, ATE0098000) represent different manufacturing lot codes or distribution channels. Selection among these variants is based on procurement availability and inventory allocation rather than technical performance differences.

Q: Are the substitute parts compatible with the original PCB layout?

A: Yes. All substitute parts maintain the identical 2917 (7343 Metric) package footprint with dimensions of 0.287" L x 0.169" W (7.30mm x 4.30mm) and maximum seated height of 0.075" (1.90mm). Surface mount placement and soldering processes require no modification.

Q: What is the impact of RoHS compliance differences?

A: The original T520V337M004ASE009 is RoHS non-compliant, while all active substitutes are ROHS3 compliant. For new designs and applications subject to RoHS regulations, the compliant substitutes are required. For legacy system maintenance, compliance requirements depend on applicable regional and customer specifications.

Q: Can these parts be used interchangeably in automated assembly?

A: Yes. All substitute parts are available in Tape & Reel (TR) packaging format, which is standard for automated pick-and-place assembly equipment. The identical package dimensions and lead spacing ensure compatibility with existing assembly tooling and programming.

Q: What is the MSL rating and why is it important?

A: All parts carry an MSL (Moisture Sensitivity Level) rating of 3 with a 168-hour floor life. This rating specifies handling and storage requirements to prevent moisture absorption that could compromise solder joint reliability. Parts must be stored in controlled humidity environments and baked according to IPC standards prior to reflow soldering if floor life is exceeded.
