Substitute Part Grouping Explanation

Substitute parts for the T520V157M006ASE012 are qualified based on strict electrical and mechanical parameter matching within the KEMET KO-CAP® T520 series. The substitution logic is governed by the following criteria:

Primary Matching Parameters:

• Capacitance: 150 µF (exact match required)
• Voltage Rating: 6.3 V (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• ESR @ 100 kHz: 12 mOhm (exact match required)
• Type: Molded Tantalum Polymer (exact match required)
• Operating Temperature Range: -55°C to 105°C (exact match required)
• Mounting Type: Surface Mount (exact match required)

Secondary Considerations:

• Packaging format (Tape & Reel vs. Bulk)
• Product status (Active vs. Obsolete)
• RoHS compliance status
• Inventory availability

Parts meeting all primary matching parameters are classified as direct equivalents. Differences in packaging format and compliance certifications do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

T520V157M006ATE012 (Direct Equivalent - Recommended Primary Substitute)

This part is the preferred substitute for the obsolete T520V157M006ASE012. It maintains identical electrical and mechanical specifications while offering active product status and ROHS3 compliance. The transition from bulk packaging to Tape & Reel format aligns with modern manufacturing and supply chain practices. This part is suitable for new designs and production continuity applications.

T520V157M006ATE012E009 (Parametric Equivalent - Secondary Substitute)

This part provides identical electrical and mechanical performance to the main part and maintains active product status with ROHS3 compliance. It serves as an alternative substitute when T520V157M006ATE012 availability is constrained. Both substitute parts are interchangeable from an engineering perspective.

Compliance Considerations

Both substitute parts achieve ROHS3 compliance, addressing regulatory requirements that may not have applied to the original obsolete part. Systems designed for RoHS non-compliant components can incorporate these substitutes without functional impact.

Frequently Asked Questions (FAQ)

Q: Can T520V157M006ATE012 be used as a direct replacement for T520V157M006ASE012?

A: Yes. Both parts share identical electrical specifications (150 µF, 6.3 V, 12 mOhm ESR), mechanical dimensions (2917 package), and operating characteristics. The primary difference is packaging format (Tape & Reel vs. Bulk) and product status (Active vs. Obsolete). Electrical and mechanical compatibility is complete.

Q: What is the difference between T520V157M006ATE012 and T520V157M006ATE012E009?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The suffix designation indicates internal manufacturing or quality tracking differences. From an engineering selection standpoint, both parts are interchangeable.

Q: Does the Tape & Reel packaging affect circuit board assembly?

A: No. Tape & Reel packaging is a supply format used for automated pick-and-place assembly. Once mounted on the circuit board, the component functions identically to bulk-packaged versions. The physical component dimensions and electrical performance remain unchanged.

Q: Are the substitute parts suitable for new product designs?

A: Yes. Both T520V157M006ATE012 and T520V157M006ATE012E009 carry active product status and ROHS3 compliance, making them appropriate for new designs. The obsolete status of the original part necessitates transition to these active alternatives.

Q: What is the significance of ROHS3 compliance on the substitute parts?

A: ROHS3 compliance indicates conformance to current regulatory standards for restricted hazardous substances. This certification is relevant for products destined for markets with RoHS requirements. The original part's non-compliant status does not affect electrical function but may present regulatory considerations for certain applications or markets.

Q: Can these parts be used interchangeably in existing assemblies?

A: Yes. All three parts (main and substitutes) share identical electrical parameters, mechanical dimensions, and thermal characteristics. Substitution in existing assemblies requires no circuit modifications or re-qualification testing based on electrical or mechanical grounds.
