RZW331M1EBK-1012S Equivalent & Substitute Parts

Part Overview

The RZW331M1EBK-1012S is an aluminum electrolytic capacitor manufactured by SURGE, rated at 330 µF capacitance with 20% tolerance and 25 V rated voltage. This radial, through-hole component is designed for general-purpose applications requiring stable capacitance performance across industrial temperature ranges. The part is currently Active in product status and ROHS3 compliant.

Equivalent and substitute parts are identified based on matching electrical specifications (capacitance, voltage rating, tolerance) and mechanical parameters (package type, lead spacing, physical dimensions) that ensure functional interchangeability within the same application circuit.

Substitute Part Grouping Explanation

Substitution of the RZW331M1EBK-1012S is determined by strict equivalence across the following parameters:

Electrical Equivalence Criteria:

• Capacitance: 330 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: 25 V (exact match required)
• Operating Temperature Range: -40°C ~ 105°C (exact match required)
• Lifetime: 7000 Hrs @ 105°C (exact match required)

Mechanical Equivalence Criteria:

• Package Type: Radial, Can (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 0.197" (5.00 mm) (exact match required)
• Physical Dimensions: 0.394" Dia (10.00 mm) × 0.551" Height (exact match required)

Compliance Criteria:

• RoHS Status: ROHS3 Compliant (required for regulatory compatibility)
• Polarization: Polar (exact match required)

All substitute parts listed meet these criteria and are therefore electrically and mechanically interchangeable with the main part number.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status): The EKY-250ELL331MJC5S manufactured by Chemi-Con is the recommended substitute. This part maintains Active product status, ensuring continued availability and manufacturer support. It carries ROHS3 compliance and meets all electrical and mechanical equivalence requirements. With 12,719 units in stock, this part provides supply continuity.

Secondary Selection (Limited Availability): The 25YXH330MEFC10X12.5 manufactured by Rubycon is designated as Last Time Buy. This part meets all electrical and mechanical specifications but has restricted availability due to its product lifecycle status. Selection of this part should account for long-term supply constraints.

Tertiary Selection (Obsolescence Risk): The 25YXF330MEFC10X12.5 manufactured by Rubycon is marked Not For New Designs. This designation indicates the part is in obsolescence phase. While electrically and mechanically equivalent, this part should not be selected for new circuit designs or long-term production applications.

All three substitute parts are ROHS3 compliant and suitable for applications requiring regulatory compliance with hazardous substance restrictions.

Frequently Asked Questions (FAQ)

Q: Can the EKY-250ELL331MJC5S be used as a direct replacement for the RZW331M1EBK-1012S?

A: Yes. The EKY-250ELL331MJC5S is electrically and mechanically equivalent. Both parts share identical capacitance (330 µF), voltage rating (25 V), tolerance (±20%), operating temperature range (-40°C ~ 105°C), and physical dimensions (0.394" diameter, 0.551" height, 5.00 mm lead spacing). Both are ROHS3 compliant and rated for 7000 hours at 105°C. Direct substitution in the PCB layout and circuit schematic is supported.

Q: What is the difference between the Rubycon YXF and YXH series substitutes?

A: Both the 25YXF330MEFC10X12.5 and 25YXH330MEFC10X12.5 meet the electrical and mechanical specifications of the main part. The primary difference is product lifecycle status: YXF is Not For New Designs, while YXH is Last Time Buy. The YXH series exhibits lower impedance (80 mOhms versus 160 mOhms) and higher ripple current capability at low frequency (475.75 mA @ 120 Hz versus 406 mA @ 120 Hz), but these differences do not affect functional interchangeability for general-purpose applications.

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

A: Only the EKY-250ELL331MJC5S (Chemi-Con) carries Active product status and is suitable for new designs. The Rubycon parts (25YXF330MEFC10X12.5 and 25YXH330MEFC10X12.5) are restricted from new designs due to their obsolescence phase designations. For long-term production and new circuit development, the Chemi-Con part is the appropriate selection.

Q: Do all substitute parts fit the same PCB footprint?

A: Yes. All substitute parts share identical mechanical specifications: 0.394" diameter can, 0.551" maximum seated height, and 0.197" (5.00 mm) lead spacing. PCB layout modifications are not required when substituting any of these parts.

Q: What is the inventory status of each substitute part?

A: The EKY-250ELL331MJC5S has 12,719 units in stock. The 25YXH330MEFC10X12.5 has 1,768 units in stock. The 25YXF330MEFC10X12.5 has 1,017 units in stock. The main part RZW331M1EBK-1012S has 838 units in stock.

Q: Are all parts compliant with RoHS3 regulations?

A: Yes. All parts listed, including the main part and all substitutes, are ROHS3 compliant. This ensures compatibility with applications and markets requiring hazardous substance restrictions.
