Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECO-S2WP470BA is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 47 µF (exact match required)
• Voltage Rating: 450 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required for PCB compatibility)
• Case Diameter: 0.866" (22.00mm) (exact match required for mechanical fit)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can - Snap-In (exact match required)

The substitute part B43501A5476M000 manufactured by EPCOS - TDK Electronics meets all critical electrical and mechanical parameters for direct substitution. While secondary parameters such as ESR, ripple current ratings, and lifetime specifications differ, these variations remain within acceptable operational ranges for general purpose applications.

Parameter Comparison

Engineering Selection Recommendations

The ECO-S2WP470BA is classified as obsolete. The B43501A5476M000 provides electrical and mechanical equivalence for direct substitution in applications currently using the Panasonic part.

The EPCOS - TDK substitute carries a product status of "Not For New Designs," indicating limited long-term availability. For new designs, evaluation of current-generation alternatives from active product lines is recommended based on the same critical parameters: 47 µF capacitance, 450 V rating, ±20% tolerance, 10.00mm lead spacing, 22.00mm case diameter, and radial snap-in package configuration.

The substitute part demonstrates improved performance characteristics, including lower ESR (2.82 Ohm vs. 4.233 Ohm) and extended lifetime rating (10000 Hrs vs. 3000 Hrs at 85°C). The maximum seated height increases from 0.984" to 1.063", requiring verification of available PCB clearance in the target application.

Frequently Asked Questions (FAQ)

Q: Can B43501A5476M000 be used as a direct replacement for ECO-S2WP470BA?

A: Yes. Both parts share identical capacitance (47 µF), voltage rating (450 V), tolerance (±20%), lead spacing (10.00mm), case diameter (22.00mm), and package configuration (radial snap-in). The 0.079" (2.00mm) increase in maximum seated height must be verified against available PCB clearance.

Q: What are the critical parameters for substitution?

A: Capacitance value, voltage rating, tolerance, lead spacing, case diameter, and package type must match exactly. These parameters determine mechanical fit and electrical performance in the circuit.

Q: Are there compliance or certification differences between the parts?

A: The ECO-S2WP470BA carries REACH Affected status. The B43501A5476M000 is ROHS3 Compliant and REACH Unaffected. Both parts are classified EAR99 for export control purposes.

Q: What is the significance of the product status classifications?

A: ECO-S2WP470BA is obsolete, indicating discontinued production. B43501A5476M000 is marked "Not For New Designs," indicating limited availability and no recommended use in new product development. Both statuses necessitate identification of current-generation alternatives for long-term supply chain planning.

Q: How do the performance characteristics differ?

A: The substitute part exhibits lower equivalent series resistance (2.82 Ohm vs. 4.233 Ohm) and extended operational lifetime (10000 Hrs vs. 3000 Hrs at 85°C). Operating temperature range extends to -40°C (vs. -25°C minimum). These improvements do not affect substitution compatibility.
