Substitute Part Grouping Explanation

Substitution eligibility for the 336SML025M is determined by strict parametric matching across the following criteria:

Primary Matching Parameters:

• Capacitance value: 33 µF (exact match required)
• Voltage rating: 25 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package type: 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 × 0.260" W (6.60mm × 6.60mm) (exact match required)
• Operating temperature range: -40°C ~ 85°C (exact match required)
• Lifetime rating: 2000 Hrs @ 85°C (exact match required)

Secondary Performance Parameters:

• ESR (Equivalent Series Resistance) @ 120 Hz
• Ripple current ratings @ 120 Hz and high frequency
• RoHS and REACH compliance status

All substitute parts listed below meet the primary matching parameters. Variations in secondary performance parameters are noted in the comparison table and do not disqualify substitution eligibility when primary parameters align.

Engineering Selection Recommendations

NACE330M25V6.3X5.5TR13F (NIC Components Corp)

This substitute meets all primary parametric requirements for direct replacement of the 336SML025M. The part carries Active product status with RoHS compliance and REACH Unaffected designation. ESR performance is superior at 7.04 Ohm compared to 8.038 Ohm, indicating lower impedance characteristics. Ripple current ratings are slightly lower but remain within acceptable operational margins. Tape & Reel packaging format supports high-volume production environments. Inventory availability of 8931 units provides supply security.

UWJ1E330MCL1GB (Nichicon)

This substitute satisfies all primary parametric matching criteria. However, the part is classified as Obsolete product status, indicating discontinued manufacturing and potential long-term supply uncertainty. ESR data is not specified in available documentation. REACH Affected status requires compliance verification for applications subject to REACH regulations. Ripple current ratings are lower than the primary part. Cut Tape & Digi-Reel® packaging format is suitable for lower-volume or manual assembly operations. This part should be selected only when supply of active alternatives is unavailable and obsolescence risk is acceptable for the application timeline.

Frequently Asked Questions (FAQ)

Q: Can NACE330M25V6.3X5.5TR13F be used as a direct replacement for 336SML025M without PCB layout modifications?

A: Yes. Both parts share identical physical dimensions (0.248" Dia × 0.217" Height), surface mount land size (0.260" L × 0.260" W), and mounting type (Surface Mount). No PCB layout changes are required.

Q: What is the significance of the ESR difference between 336SML025M (8.038 Ohm) and NACE330M25V6.3X5.5TR13F (7.04 Ohm)?

A: ESR (Equivalent Series Resistance) affects impedance and heat dissipation characteristics. The lower ESR of NACE330M25V6.3X5.5TR13F indicates reduced impedance, which can improve filtering performance and reduce thermal stress in high-ripple-current applications. This difference does not prevent substitution but represents a performance advantage.

Q: Why is UWJ1E330MCL1GB listed as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. While existing inventory may be available, future supply cannot be guaranteed. Selection of this part should be limited to applications where active alternatives are unavailable or where existing stock is being consumed.

Q: Are there compliance differences between the three parts?

A: All three parts are ROHS3 Compliant or RoHS Compliant. The 336SML025M and NACE330M25V6.3X5.5TR13F are REACH Unaffected, while UWJ1E330MCL1GB is REACH Affected. For applications subject to REACH regulations, the first two options are preferred.

Q: What packaging format should be selected for production?

A: NACE330M25V6.3X5.5TR13F is supplied in Tape & Reel (TR) format, optimized for automated assembly lines. UWJ1E330MCL1GB is supplied in Cut Tape (CT) & Digi-Reel® format, suitable for lower-volume or manual assembly. Selection depends on production volume and assembly equipment capabilities.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or reflow processes.

Q: Can ripple current ratings be used to determine which substitute is best?

A: Ripple current ratings indicate the maximum AC current the capacitor can handle at specified frequencies. The 336SML025M has the highest ripple current ratings (67 mA @ 120 Hz, 100.5 mA @ 100 kHz). NACE330M25V6.3X5.5TR13F has slightly lower ratings (63 mA @ 120 Hz, 91.35 mA @ 100 kHz), while UWJ1E330MCL1GB has the lowest (52 mA @ 120 Hz, 78 mA @ 10 kHz). Selection should be based on actual circuit ripple current requirements. If circuit ripple current exceeds the substitute's rating, that part is not suitable.
