Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SLP103M035C4P3 are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Capacitance: 10000 µF (exact match required)
• Voltage Rating: 35 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Operating Temperature Range: -40°C to 105°C (exact match required)
• Lifetime: 3000 Hrs @ 105°C (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required)
• Diameter: 0.984" (25.00mm) (exact match required)
• Package Type: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)

Allowable Variation Parameters:

• ESR (Equivalent Series Resistance): Variation permitted within functional limits
• Height - Seated (Max): Variation permitted within PCB layout constraints
• Ripple Current ratings: Variation permitted if application requirements are met

Two substitute parts meet these criteria: SLP103M035C7P3 (direct manufacturer equivalent) and 381LX103M035J452 (similar manufacturer alternative).

Parameter Comparison

Engineering Selection Recommendations

SLP103M035C7P3 (Direct Manufacturer Substitute):

This part is the primary equivalent for the SLP103M035C4P3. Both components are from the same manufacturer series (SLP0712TE 750W) and share identical electrical specifications. The SLP103M035C7P3 features a reduced seated height of 1.575" (40.00mm) compared to 1.772" (45.00mm) on the main part, providing a space-saving advantage in height-constrained PCB layouts. ESR specification remains at 53 mOhm, maintaining electrical performance characteristics. All compliance certifications (ROHS3, REACH Unaffected, EAR99) are identical. Current inventory availability is 9817 pieces.

381LX103M035J452 (Similar Manufacturer Alternative):

This part qualifies as a functional substitute based on matching capacitance, voltage rating, tolerance, temperature range, and lifetime specifications. The 381LX series represents an alternative product line within Cornell Dubilier Electronics. The seated height is 1.850" (47.00mm), which is 0.078" taller than the main part. Ripple current at 20 kHz is specified at 3.7 A compared to 4 A on the main part. ESR is not specified for this part. All compliance certifications match the main part. Current inventory availability is 13247 pieces.

Selection Criteria:

• Use SLP103M035C7P3 when PCB height constraints favor a more compact component or when direct series continuity is required.
• Use 381LX103M035J452 when higher inventory availability is prioritized and the additional 0.078" height is acceptable within design constraints.
• All three parts maintain ROHS3 compliance and are suitable for general-purpose applications across the specified temperature range.

Frequently Asked Questions (FAQ)

Q: Can SLP103M035C7P3 be used as a direct replacement for SLP103M035C4P3?

A: Yes. Both parts share identical electrical specifications (10000 µF, 35 V, ±20% tolerance, 53 mOhm ESR, 3000 Hrs @ 105°C). The primary difference is the seated height: SLP103M035C7P3 measures 1.575" (40.00mm) versus 1.772" (45.00mm) for the SLP103M035C4P3. Verify PCB layout clearance before substitution.

Q: What are the mechanical compatibility requirements for these substitutes?

A: All three parts maintain identical lead spacing (0.394" / 10.00mm) and diameter (0.984" / 25.00mm), ensuring PCB footprint compatibility. Height differences range from 1.575" to 1.850", which may affect component clearance in confined spaces. Verify height constraints in your specific application.

Q: Are there electrical performance differences between the substitute parts?

A: SLP103M035C4P3 and SLP103M035C7P3 have identical ESR specifications (53 mOhm @ 120Hz). The 381LX103M035J452 does not specify ESR but provides ripple current ratings of 3.2 A @ 120 Hz and 3.7 A @ 20 kHz. For applications sensitive to ESR characteristics, SLP103M035C7P3 is the preferred substitute.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 Compliant, REACH Unaffected, and classified as EAR99. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all parts.

Q: What is the difference between "Direct Manufacturer Part Number" and "Similar Manufacturer Part Number" substitutes?

A: SLP103M035C7P3 is classified as a direct substitute because it belongs to the same manufacturer series (SLP0712TE 750W) and shares all critical electrical parameters. The 381LX103M035J452 is a similar substitute from an alternative product line (381LX series) that meets the same functional requirements but may have minor specification variations in non-critical parameters.

Q: Which substitute should I select for new designs?

A: For new designs, either SLP103M035C7P3 or 381LX103M035J452 are acceptable based on availability and PCB layout constraints. SLP103M035C7P3 offers the advantage of direct series continuity and identical ESR specification. Verify component height clearance and ripple current requirements for your specific application.
