Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWR11FH685KB is determined by the following critical parameters:

Primary Substitution Criteria:

• Product Category: Tantalum Capacitors
• Component Type: CAP TANT (Molded Tantalum)
• Moisture Sensitivity Level: 1 (Unlimited)
• ECCN Classification: EAR99
• HTSUS Code: 8532.21.0050

The substitute part T491B685K010AT from KEMET meets all primary substitution criteria. Both parts share identical MSL ratings, ECCN classifications, and HTSUS codes, confirming compatibility at the component category level. The substitute maintains the same functional classification as a molded tantalum capacitor and carries equivalent regulatory designations.

Parameter Comparison

Engineering Selection Recommendations

The T491B685K010AT from KEMET is qualified as a substitute for the CWR11FH685KB based on matching regulatory classifications, identical MSL ratings, and equivalent ECCN and HTSUS designations. Both parts maintain Active product status, ensuring continued availability and manufacturer support.

A key distinction exists in RoHS compliance status: the CWR11FH685KB is RoHS non-compliant, while the T491B685K010AT is ROHS3 compliant. This difference must be evaluated against specific application requirements and regional regulatory mandates. In applications where RoHS3 compliance is mandatory, the KEMET substitute provides enhanced regulatory alignment. In applications where RoHS non-compliance is acceptable or required, both parts remain functionally equivalent.

The substitute part is available in Tape & Reel (TR) packaging with significantly higher inventory (53,300 pieces), compared to the Bulk packaging of the main part (690 pieces). Packaging format selection depends on assembly process requirements and procurement volume specifications.

Frequently Asked Questions (FAQ)

Q: What determines whether T491B685K010AT can substitute for CWR11FH685KB?

A: Substitution is based on matching product category (Tantalum Capacitors), component type (CAP TANT), MSL rating (1 - Unlimited), ECCN classification (EAR99), and HTSUS code (8532.21.0050). Both parts meet these criteria.

Q: Does the RoHS compliance difference affect substitution eligibility?

A: RoHS compliance status is a regulatory attribute that must align with application requirements. The CWR11FH685KB is RoHS non-compliant while T491B685K010AT is ROHS3 compliant. Selection depends on whether your application mandates RoHS compliance or permits non-compliant components.

Q: What is the significance of the different packaging formats?

A: CWR11FH685KB is supplied in Bulk packaging, while T491B685K010AT is supplied in Tape & Reel (TR) format. Packaging selection depends on assembly equipment compatibility and procurement volume. TR packaging is standard for automated surface mount assembly processes.

Q: Are there any moisture sensitivity concerns with either part?

A: Both parts carry MSL 1 (Unlimited) ratings, indicating no moisture sensitivity restrictions. Both parts can be stored and handled without bake-out procedures or moisture barrier packaging requirements.

Q: What electrical parameters are specified for the substitute part?

A: The T491B685K010AT is specified with 6.8 µF capacitance, 10 V rated voltage, ±10% tolerance, 3.5 Ohm ESR, and operating temperature range of -55°C to 125°C with 2000 hours lifetime at 125°C.
