Equivalent & Substitute Parts for 335SML050M

Part Overview

The 335SML050M is a 3.3 µF, 50 V aluminum electrolytic capacitor in surface mount radial can package manufactured by Cornell Dubilier / Illinois Capacitor. This component is classified as Active product status and is designed for general purpose applications requiring stable capacitance performance across industrial temperature ranges.

Substitute parts become necessary when the primary part experiences supply constraints, inventory depletion, or when design flexibility permits selection from qualified alternatives meeting identical electrical and mechanical specifications. The 335SML050M has one parametric equivalent available: UWJ1H3R3MCL1GB from Nichicon, which maintains critical performance parameters while differing in product lifecycle status and certain compliance attributes.

Substitute Part Grouping Explanation

Substitution eligibility for the 335SML050M is determined by strict equivalence across all electrical and mechanical parameters. The substitute part UWJ1H3R3MCL1GB qualifies as a parametric equivalent based on the following matching criteria:

Electrical Parameters (Must Match):

• Capacitance: 3.3 µF
• Voltage Rating: 50 V
• Tolerance: ±20%
• Operating Temperature Range: -40°C ~ 85°C
• Lifetime @ Temperature: 2000 Hrs @ 85°C
• Polarization: Polar

Mechanical Parameters (Must Match):

• Package Type: Radial, Can - SMD
• Physical Dimensions: 0.157" Dia (4.00mm) × 0.217" H (5.50mm)
• Surface Mount Land Size: 0.169" L × 0.169" W (4.30mm × 4.30mm)
• Mounting Type: Surface Mount

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The UWJ1H3R3MCL1GB maintains complete equivalence across all specified parameters, enabling direct substitution in circuit designs and PCB layouts without modification.

Engineering Selection Recommendations

Primary Part Selection (335SML050M): The 335SML050M is the preferred selection for new designs and ongoing production. This component maintains Active product status, ensuring long-term availability and manufacturer support. The part is REACH Unaffected, simplifying compliance documentation for applications subject to REACH regulations. With 681 pieces in current inventory, supply continuity is established for near-term requirements.

Substitute Part Selection (UWJ1H3R3MCL1GB): The UWJ1H3R3MCL1GB from Nichicon qualifies as a direct parametric equivalent and may be selected when the primary part experiences supply constraints. This substitute maintains electrical and mechanical equivalence across all critical parameters, including capacitance, voltage rating, operating temperature range, and physical dimensions. However, the following conditions apply:

• Product Status: The UWJ1H3R3MCL1GB is classified as Obsolete. Selection of this part should be limited to applications where existing inventory is available and long-term supply is not required.
• REACH Compliance: The substitute is REACH Affected, requiring additional compliance verification for applications subject to REACH regulations. Design teams must confirm that REACH Affected status is acceptable within their regulatory framework.
• Inventory Availability: 3,872 pieces are currently in stock, providing adequate supply for immediate substitution needs.

Selection Logic: Choose 335SML050M for new designs, production continuity, and applications requiring long-term component availability. Select UWJ1H3R3MCL1GB only when primary part supply is unavailable and REACH Affected status is acceptable within project requirements.

Frequently Asked Questions (FAQ)

Q: Can UWJ1H3R3MCL1GB be used as a direct replacement for 335SML050M without PCB modification?

A: Yes. The UWJ1H3R3MCL1GB is a parametric equivalent with identical physical dimensions (0.157" Dia × 0.217" H), surface mount land size (0.169" L × 0.169" W), and mounting type (Surface Mount). No PCB layout changes are required for mechanical or electrical compatibility.

Q: What is the difference in ripple current specifications between the two parts?

A: The 335SML050M specifies 18 mA @ 120 Hz and 27 mA @ 100 kHz. The UWJ1H3R3MCL1GB specifies 17 mA @ 120 Hz and 25.5 mA @ 10 kHz. The low-frequency ripple current values are similar (18 mA vs. 17 mA). High-frequency ripple current specifications are measured at different test frequencies (100 kHz vs. 10 kHz), making direct comparison impractical. Both parts meet the 2000 Hrs @ 85°C lifetime requirement and operate across the identical -40°C ~ 85°C temperature range.

Q: Why is the ESR value not provided for the UWJ1H3R3MCL1GB?

A: The ESR (Equivalent Series Resistance) specification of 60.29 Ohm @ 120 Hz is provided only for the 335SML050M. The UWJ1H3R3MCL1GB datasheet does not include this parameter in the available technical documentation. If ESR performance is critical to circuit design, the 335SML050M should be selected.

Q: What does "Obsolete" product status mean for the UWJ1H3R3MCL1GB?

A: Obsolete status indicates that the UWJ1H3R3MCL1GB is no longer in active production by Nichicon. Existing inventory (3,872 pieces) is available for purchase, but no new manufacturing runs are planned. This part should be selected only when primary part supply is constrained and existing stock is sufficient for project requirements.

Q: Are there compliance differences between the two parts?

A: Yes. The 335SML050M is REACH Unaffected, while the UWJ1H3R3MCL1GB is REACH Affected. Both parts are ROHS3 Compliant and have Moisture Sensitivity Level 1 (Unlimited). Applications subject to REACH regulations must confirm that REACH Affected status is acceptable before selecting the UWJ1H3R3MCL1GB.

Q: Can both parts be used interchangeably in the same production batch?

A: Both parts meet identical electrical and mechanical specifications and can function interchangeably in circuit operation. However, using both parts in the same production batch introduces supply chain complexity and compliance documentation requirements. Standardization on a single part number is recommended for production consistency.

Q: What is the packaging difference between the two parts?

A: The 335SML050M is supplied in standard packaging. The UWJ1H3R3MCL1GB is supplied in Cut Tape (CT) & Digi-Reel® packaging. Both packaging formats are compatible with automated surface mount assembly equipment. Packaging selection should align with production line capabilities and inventory management procedures.
