EY1E331MP50816 Equivalent & Substitute Parts

Part Overview

The EY1E331MP50816 is a 330 µF, 25 V aluminum electrolytic capacitor in radial through-hole configuration, manufactured by Chinsan (Elite) under the EY series. This component is rated for 7000 hours of operation at 105°C and is designed for general-purpose applications requiring stable capacitance and ripple current handling. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent substitute parts are identified to provide design flexibility, ensure supply chain continuity, and support component procurement strategies when the primary part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EY1E331MP50816 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 330 µF (exact match required)
• Rated voltage: 25 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime rating: 7000 Hrs @ 105°C (exact match required)
• Operating temperature range: -55°C ~ 105°C (exact match required)
• Polarization: Polar (exact match required)

Mechanical Parameters:

• Mounting type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)
• Lead spacing: 0.138" (3.50mm) (exact match required)
• Size / Dimension: 0.315" Dia (8.00mm) (exact match required)
• Height - Seated (Max): 0.689" (17.50mm) (exact match required)

Compliance Parameters:

• RoHS3 Compliant status (required for regulatory alignment)

Substitute parts meeting all electrical, mechanical, and compliance criteria are classified as parametric equivalents and are suitable for direct replacement in circuit designs without modification to PCB layout or schematic topology.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: EY1E331MP50816 (Chinsan Elite)

The EY1E331MP50816 maintains Active product status with established supply availability (711 pcs in stock). This part is ROHS3 compliant and carries MSL 1 rating, indicating no moisture sensitivity constraints during storage and handling. Selection of this part is appropriate for applications where Chinsan (Elite) component qualification is established or preferred.

Substitute Part: 860160474019 (Würth Elektronik WCAP-ATLL Series)

The 860160474019 is a parametric equivalent meeting all critical electrical and mechanical specifications. This part is also Active status with higher inventory availability (1350 pcs in stock) and ROHS3 compliance. The Würth Elektronik WCAP-ATLL series demonstrates equivalent performance across capacitance, voltage rating, temperature lifetime, and mechanical form factor. Ripple current specifications and impedance values remain within acceptable operational tolerances for general-purpose applications.

Selection of the 860160474019 is appropriate for:

• Supply chain continuity when primary part availability is constrained
• Design flexibility supporting multi-source component strategies
• Applications where Würth Elektronik component qualification is established

Both parts are suitable for direct substitution without PCB redesign or circuit topology modification.

Frequently Asked Questions (FAQ)

Q: Can the 860160474019 (Würth Elektronik) be used as a direct replacement for the EY1E331MP50816 (Chinsan Elite)?

A: Yes. Both parts are parametric equivalents with identical capacitance (330 µF), voltage rating (25 V), tolerance (±20%), lifetime rating (7000 Hrs @ 105°C), operating temperature range (-55°C ~ 105°C), and mechanical dimensions. Lead spacing, case size, and height are identical. Both are through-hole radial can packages with ROHS3 compliance. Direct substitution is supported without circuit modification.

Q: Are there differences in ripple current handling between these parts?

A: Minor differences exist within acceptable operational ranges. The EY1E331MP50816 specifies 425 mA @ 120 Hz and 850 mA @ 100 kHz. The 860160474019 specifies 400.2 mA @ 120 Hz and 960 mA @ 100 kHz. These variations remain within general-purpose application tolerances and do not preclude substitution.

Q: Do both parts have the same impedance characteristics?

A: The parts have slightly different impedance values. The EY1E331MP50816 specifies 220 mOhms, while the 860160474019 specifies 250 mOhms. This 30 mOhm difference is within acceptable tolerance for general-purpose applications and does not prevent substitution.

Q: What is the significance of the MSL (Moisture Sensitivity Level) difference?

A: The EY1E331MP50816 carries MSL 1 (Unlimited), indicating no moisture sensitivity constraints. The 860160474019 lists MSL as Not Applicable, indicating the manufacturer does not classify this parameter for this product line. Both ratings are compatible with standard handling and storage procedures. This difference does not affect substitution suitability.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the EY1E331MP50816 and 860160474019 are ROHS3 compliant, meeting current regulatory requirements for hazardous substance restrictions.

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

A: Yes. Identical mechanical dimensions (0.315" diameter, 0.689" height, 0.138" lead spacing), matching through-hole radial can package configuration, and equivalent electrical specifications support interchangeable use without PCB layout modification or design revision.

Q: What is the lead spacing for both parts?

A: Both parts have identical lead spacing of 0.138" (3.50mm), ensuring compatible PCB hole patterns and footprints.

Q: Are there any application limitations for either substitute part?

A: Both parts are rated for general-purpose applications with identical operating temperature ranges (-55°C ~ 105°C) and lifetime ratings (7000 Hrs @ 105°C). No application-specific limitations differentiate the parts.
