Substitute Part Grouping Explanation

Substitute parts for the 336KXM035M are classified based on the following substitution criteria:

Parametric Equivalent Classification: Parts that maintain identical or functionally equivalent electrical and mechanical specifications are classified as parametric equivalents. These parts share the same capacitance (33 µF), tolerance (±20%), voltage rating (35 V), operating temperature range (-55°C to 105°C), lifetime rating (2000 Hrs @ 105°C), lead spacing (0.079"), diameter (0.197"), height (0.492"), and mounting type (Through Hole, Radial Can).

Upgrade Classification: Parts that exceed the original voltage rating while maintaining all other critical parameters are classified as upgrades. These parts provide enhanced voltage margin and are suitable for applications where higher voltage headroom is beneficial.

The following parameters determine substitution eligibility:

Capacitance: 33 µF (exact match required)
Tolerance: ±20% (exact match required)
Operating Temperature: -55°C to 105°C (exact match required)
Lead Spacing: 0.079" / 2.00 mm (exact match required)
Physical Dimensions: 0.197" Dia × 0.492" Height (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)
Polarization: Polar (exact match required)

Engineering Selection Recommendations

336KXM035M (Main Part - Active Status)

The 336KXM035M remains the primary selection for new designs and applications requiring the original specification. This part maintains Active product status with 678 pieces in current inventory. The component is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

UPS1V330MDD (Parametric Equivalent - Obsolete Status)

The UPS1V330MDD manufactured by Nichicon provides parametric equivalence to the 336KXM035M with matching capacitance, voltage rating, tolerance, temperature range, and physical dimensions. This part is classified as Obsolete; however, 665 pieces remain in inventory. The UPS1V330MDD is ROHS3 compliant and REACH unaffected. This substitute is suitable for direct replacement in applications where the original part becomes unavailable, provided that inventory availability is confirmed at the time of procurement.

UKA1H330MDD (Upgrade - Obsolete Status)

The UKA1H330MDD manufactured by Nichicon provides an upgrade path with a higher voltage rating of 50 V compared to the original 35 V specification. All other critical parameters including capacitance, tolerance, operating temperature range, lifetime rating, and physical dimensions remain equivalent. This part is classified as Obsolete; however, 5735 pieces remain in inventory. The UKA1H330MDD is ROHS3 compliant and REACH unaffected. This substitute is suitable for applications where increased voltage margin is beneficial or where the original part is unavailable. The higher voltage rating does not negatively impact circuit performance in 35 V applications.

Frequently Asked Questions (FAQ)

Q: Can the UKA1H330MDD (50 V) be used in place of the 336KXM035M (35 V)?

A: Yes. The UKA1H330MDD is rated for 50 V, which exceeds the 35 V requirement of the original specification. A higher voltage-rated capacitor operates safely in lower voltage applications. All other electrical and mechanical parameters match the original part, including capacitance (33 µF), tolerance (±20%), operating temperature range (-55°C to 105°C), lifetime (2000 Hrs @ 105°C), and physical dimensions (0.197" Dia × 0.492" Height).

Q: What is the difference between the UPS1V330MDD and UKA1H330MDD?

A: The primary difference is voltage rating. The UPS1V330MDD maintains the original 35 V rating, while the UKA1H330MDD provides a 50 V rating. Both parts share identical capacitance (33 µF), tolerance (±20%), operating temperature range (-55°C to 105°C), lifetime (2000 Hrs @ 105°C), and physical dimensions. The UKA1H330MDD is classified as an upgrade due to its higher voltage capability.

Q: Are all substitute parts physically compatible with the original PCB layout?

A: Yes. All substitute parts maintain identical lead spacing (0.079" / 2.00 mm), diameter (0.197" / 5.00 mm), and height (0.492" / 12.50 mm). All parts are Through Hole mounted in Radial, Can package configuration. Direct PCB footprint compatibility is confirmed.

Q: What is the product status of the substitute parts?

A: Both substitute parts (UKA1H330MDD and UPS1V330MDD) are classified as Obsolete. The original part (336KXM035M) maintains Active status. Obsolete classification indicates that the manufacturer has discontinued production; however, inventory remains available from authorized distributors.

Q: Are the substitute parts RoHS and REACH compliant?

A: Yes. All parts listed, including the main part (336KXM035M) and both substitutes (UKA1H330MDD and UPS1V330MDD), are ROHS3 compliant and REACH unaffected. These certifications confirm compliance with current environmental and hazardous substance regulations.

Q: How do ripple current ratings compare between the parts?

A: The 336KXM035M specifies 100 mA @ 120 Hz and 250 mA @ 100 kHz. The UPS1V330MDD specifies 27.2 mA @ 120 Hz and 160 mA @ 100 kHz. The UKA1H330MDD specifies 90 mA @ 120 Hz and 180 mA @ 10 kHz. Ripple current specifications vary between manufacturers and series. Application-specific ripple current requirements must be evaluated against the selected substitute part's rating.

Q: Can these parts be used interchangeably in audio applications?

A: The UKA1H330MDD is designated for Audio applications, while the 336KXM035M and UPS1V330MDD are designated for General Purpose applications. All parts share identical electrical characteristics (capacitance, voltage, tolerance, temperature range, lifetime) and physical dimensions. Application suitability depends on circuit-specific requirements beyond component classification.
