Substitute Part Grouping Explanation

Substitute parts for the 338LBB080M2DD are classified based on strict electrical and mechanical parameter alignment. The substitution criteria are:

Primary Matching Parameters:

• Capacitance: 3300 µF (exact match required)
• Voltage Rating: 80 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime: 3000 Hrs @ 85°C (exact match required)
• Operating Temperature: -40°C ~ 85°C (exact match required)
• Polarization: Polar (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required)
• Size / Dimension: 1.181" Dia (30.00mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can - Snap-In (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

All identified substitute parts meet these criteria. Variations in ESR (Equivalent Series Resistance) and ripple current specifications at different frequencies are permitted within the scope of general-purpose applications, as these parameters are not uniformly specified across all manufacturers in the provided data.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and ROHS3 compliance, meeting regulatory and environmental requirements equivalent to the primary part 338LBB080M2DD. Selection among these alternatives should be based on:

Inventory Availability: SLPX332M080E3P3 (CDE) offers the highest stock level at 9173 units, followed by LLS1K332MELB (Nichicon) at 2095 units, and 80USG3300MEFCSN30X30 (Rubycon) at 969 units.

Physical Dimensions: SLPX332M080E3P3 features a reduced seated height of 1.181" (30.00mm) compared to the primary part and other substitutes at 1.260" (32.00mm). This dimensional difference may be relevant for applications with height constraints.

Electrical Performance: The primary part 338LBB080M2DD exhibits the lowest ESR at 75.36 mOhm @ 120Hz. SLPX332M080E3P3 specifies 101 mOhm @ 120Hz. Rubycon and Nichicon parts do not specify ESR values in the provided data. All parts meet the 3000-hour lifetime specification at 85°C and operate within the -40°C to 85°C temperature range.

Compliance and Certifications: All parts are ROHS3 compliant and REACH unaffected, with identical ECCN (EAR99) and HTSUS (8532.22.0040) classifications.

Frequently Asked Questions (FAQ)

Q: Can SLPX332M080E3P3 be used as a direct replacement for 338LBB080M2DD?

A: Yes. Both parts share identical capacitance (3300 µF), voltage rating (80 V), tolerance (±20%), lifetime (3000 Hrs @ 85°C), operating temperature range (-40°C ~ 85°C), lead spacing (10.00mm), diameter (30.00mm), mounting type (Through Hole), and package style (Radial, Can - Snap-In). The seated height of SLPX332M080E3P3 is 1.181" (30.00mm) versus 1.260" (32.00mm) for the primary part. Verify PCB layout clearance before substitution.

Q: What is the difference between the three substitute parts?

A: All three substitutes meet the core electrical and mechanical specifications. SLPX332M080E3P3 (CDE) specifies ESR at 101 mOhm @ 120Hz and offers the highest inventory availability. 80USG3300MEFCSN30X30 (Rubycon) and LLS1K332MELB (Nichicon) do not specify ESR in the provided data. SLPX332M080E3P3 has a reduced seated height of 30.00mm, while the other two match the primary part at 32.00mm.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts are ROHS3 compliant, matching the compliance status of the primary part 338LBB080M2DD.

Q: Does the ESR difference between parts affect circuit performance?

A: ESR (Equivalent Series Resistance) affects ripple current handling and thermal performance. The primary part 338LBB080M2DD specifies 75.36 mOhm @ 120Hz, while SLPX332M080E3P3 specifies 101 mOhm @ 120Hz. For general-purpose applications, both values are within acceptable ranges. Applications requiring minimal ESR should prioritize the primary part or verify ESR specifications with the manufacturer for Rubycon and Nichicon alternatives.

Q: Can I use these parts interchangeably on the same PCB?

A: Electrical interchangeability is confirmed. Mechanical interchangeability requires verification of PCB hole spacing (all parts use 10.00mm lead spacing) and clearance height. SLPX332M080E3P3 has a maximum seated height of 30.00mm, while 338LBB080M2DD, 80USG3300MEFCSN30X30, and LLS1K332MELB are 32.00mm. Confirm PCB layout accommodates the specific part height before installation.

Q: What is the operating temperature range for all parts?

A: All parts operate within -40°C to 85°C. Lifetime is specified as 3000 hours at 85°C for all parts.
