336SML035M Equivalent & Substitute Parts

Part Overview

The 336SML035M is a 33 µF, 35 V aluminum electrolytic capacitor in surface mount radial can package manufactured by Cornell Dubilier / Illinois Capacitor. This component is classified as Active and serves general-purpose applications requiring stable capacitance and low equivalent series resistance in compact form factors.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory depletion, or when design flexibility permits selection from alternative manufacturers meeting identical electrical and mechanical specifications. The 336SML035M maintains full compatibility with qualified substitutes that match its core parametric requirements.

Substitute Part Grouping Explanation

Substitution of the 336SML035M is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Capacitance: 33 µF (exact match required)
• Voltage Rating: 35 V (exact match required)
• Tolerance: ±20% (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Lifetime: 2000 Hrs @ 85°C (exact match required)
• Polarization: Polar (exact match required)

Mechanical Specifications:

• Mounting Type: Surface Mount (exact match required)
• Package / Case: Radial, Can - SMD (exact match required)
• Physical Dimensions: 0.248" Dia (6.30mm) and 0.217" Height (5.50mm) (exact match required)
• Surface Mount Land Size: 0.260" L x 0.260" W (6.60mm x 6.60mm) (exact match required)

Compliance & Environmental:

• RoHS3 Compliance (exact match required)
• REACH Unaffected Status (exact match required)
• MSL Level 1 (Unlimited) (exact match required)

The substitute part UWR1V330MCL1GB from Nichicon meets all parametric and mechanical requirements for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The 336SML035M from Cornell Dubilier / Illinois Capacitor is the preferred selection when available. This part maintains Active product status, ensuring continued manufacturer support and long-term supply chain stability. Current inventory of 1167 pieces supports immediate procurement requirements.

Substitute Part Selection: The UWR1V330MCL1GB from Nichicon is a qualified parametric equivalent suitable for direct substitution when the primary part is unavailable. This substitute meets all electrical, mechanical, and compliance requirements. However, the Obsolete product status indicates this part is no longer in active production. Selection of this substitute should account for potential future supply constraints.

Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for current manufacturing standards. MSL Level 1 classification permits unlimited shelf life storage without moisture bake-out procedures.

Frequently Asked Questions (FAQ)

Q: Can UWR1V330MCL1GB replace 336SML035M in existing designs?

A: Yes. The UWR1V330MCL1GB meets all parametric and mechanical specifications required for direct substitution. Identical capacitance (33 µF), voltage rating (35 V), tolerance (±20%), operating temperature range (-40°C ~ 85°C), lifetime (2000 Hrs @ 85°C), and physical dimensions (0.248" Dia × 0.217" Height) ensure PCB-level compatibility without design modification.

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

A: Ripple current specifications differ between the parts. The 336SML035M provides 65 mA @ 120 Hz and 97.5 mA @ 100 kHz. The UWR1V330MCL1GB provides 62 mA @ 120 Hz and 93 mA @ 10 kHz. These differences do not affect substitution eligibility, as both parts satisfy the same application requirements within their rated specifications.

Q: What is the significance of the Obsolete status for UWR1V330MCL1GB?

A: Obsolete status indicates the UWR1V330MCL1GB is no longer in active production by Nichicon. While current inventory of 3137 pieces is available, future procurement may face supply limitations. This part is suitable for immediate substitution but should not be selected for new long-term production designs requiring extended supply availability.

Q: Do both parts require identical PCB land patterns?

A: Yes. Both parts use identical surface mount land sizes of 0.260" L × 0.260" W (6.60mm × 6.60mm). No PCB layout modifications are required when substituting between these parts.

Q: Are there compliance differences between the two parts?

A: No. Both parts maintain ROHS3 compliance, REACH Unaffected status, and MSL Level 1 (Unlimited) classification. Regulatory and environmental compliance requirements are identical.

Q: What is the ESR difference between these parts?

A: The 336SML035M specifies ESR of 7.033 Ohm @ 120 Hz. The UWR1V330MCL1GB does not provide ESR specification in the available data. This parameter difference does not prevent substitution, as both parts meet the same application requirements.
