Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the B43501A9477M67 is determined by strict equivalence across the following critical parameters:

Electrical specifications: Capacitance value (470 µF), tolerance (±20%), rated voltage (400 V), ESR (140 mOhm @ 100 Hz), lifetime rating (10000 Hrs @ 85°C), and ripple current capability (2.6 A @ 100 Hz) must remain identical.

Mechanical compatibility: Lead spacing (10.00 mm), physical dimensions (35.00 mm diameter, 47.00 mm height), and package type (Radial, Can - Snap-In) must match to ensure direct board-level substitution.

Regulatory compliance: RoHS3 compliance and MSL rating (1 - Unlimited) must be maintained.

Parts meeting these criteria are classified as parametric equivalents within the B43501 series and are suitable for direct replacement without circuit redesign or performance impact.

Parameter Comparison

Engineering Selection Recommendations

Both B43501A9477M67 and B43501A9477M002 are Active status products from EPCOS - TDK Electronics within the B43501 series. Both components maintain full ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for industrial and commercial applications.

Selection between these parts is determined by packaging requirements. The B43501A9477M67 is supplied in tape packaging, while the B43501A9477M002 is supplied in bulk packaging. Electrical performance, mechanical dimensions, and thermal characteristics are identical across both variants.

For applications requiring specific packaging formats for automated assembly or inventory management, the appropriate part number should be selected based on supply chain and manufacturing process requirements. Both parts are suitable for direct substitution in existing designs without modification to PCB layout or circuit topology.

Frequently Asked Questions (FAQ)
