• Voltage Rating: 80 V minimum (equal or higher ratings permitted)
• Polarization: Polar (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Type: Radial, Can - Snap-In (exact match required)
• Operating Temperature Range: -40°C to 105°C (exact match required)
• Lifetime: 3000 Hrs @ 105°C (exact match required)

Secondary Compatibility Parameters:

• Lead Spacing: 0.394" (10.00mm) preferred for PCB layout compatibility
• Physical Dimensions: Diameter and height variations acceptable within mechanical envelope constraints
• ESR and Ripple Current: Variations acceptable provided application requirements are met
• RoHS and REACH Compliance: ROHS3 Compliant and REACH Unaffected status required

Parts meeting all primary criteria are classified as direct substitutes. Parts with voltage ratings exceeding 80 V are acceptable substitutes for applications operating below the original rated voltage.

Engineering Selection Recommendations

SLP102M100A3P3 (Primary Substitute - Active Status)

The SLP102M100A3P3 is the preferred substitute for the SLP102M080A1P3. Both components are manufactured by Cornell Dubilier Electronics within the same SLP0712TE series and maintain Active product status. The SLP102M100A3P3 operates at 100 V rated voltage, providing 20 V additional voltage margin over the original 80 V specification. This higher voltage rating is compatible with applications designed for 80 V operation, as the component can safely operate at lower voltages than its rating.

Key advantages of the SLP102M100A3P3 include lower ESR (265 mOhm versus 332 mOhm), higher ripple current capacity at both 120 Hz (1.47 A versus 1.19 A) and 20 kHz (1.84 A versus 1.49 A), and Active product status ensuring continued availability. The component maintains identical lead spacing (10.00mm), capacitance (1000 µF), tolerance (±20%), and thermal specifications (3000 Hrs @ 105°C).

Physical dimensions differ: the SLP102M100A3P3 has a maximum seated height of 1.181" (30.00mm) compared to 0.984" (25.00mm) for the original part. PCB layout verification is required to confirm mechanical clearance in the application.

381LX102M080J012 (Secondary Substitute - Obsolete Status)

The 381LX102M080J012 maintains identical electrical specifications at 80 V rated voltage and 1000 µF capacitance with ±20% tolerance. This component is classified as Obsolete product status. While currently in stock (1065 Pcs), future availability cannot be assured.

The 381LX102M080J012 exhibits higher ripple current capacity (1.3 A @ 120 Hz and 1.5 A @ 20 kHz) and maintains the same 3000 Hrs @ 105°C lifetime specification. ESR is not specified for this component. Physical dimensions are larger: 0.984" diameter (25.00mm) and 1.063" maximum seated height (27.00mm), requiring PCB layout verification for mechanical compatibility.

Selection of the 381LX102M080J012 is not recommended for new designs due to Obsolete status. This component is suitable only for replacement applications where existing inventory must be maintained or where design constraints prevent use of the SLP102M100A3P3.

Frequently Asked Questions (FAQ)

Q: Can the SLP102M100A3P3 be used as a direct replacement for the SLP102M080A1P3?

A: Yes. The SLP102M100A3P3 is a direct electrical substitute. Both components share identical capacitance (1000 µF), tolerance (±20%), polarization (Polar), mounting type (Through Hole), and package configuration (Radial, Can - Snap-In). The 100 V rating of the substitute exceeds the 80 V requirement, providing additional voltage margin. Physical dimensions differ; PCB layout verification is required to confirm mechanical clearance.

Q: What is the difference between the 381LX102M080J012 and the SLP102M080A1P3?

A: Both components operate at 80 V with 1000 µF capacitance and ±20% tolerance. The primary difference is product status: the SLP102M080A1P3 is Active, while the 381LX102M080J012 is Obsolete. The 381LX102M080J012 has larger physical dimensions (0.984" diameter, 1.063" height) and higher ripple current ratings. ESR is not specified for the 381LX102M080J012. Both maintain identical thermal specifications (3000 Hrs @ 105°C) and compliance certifications (ROHS3 Compliant, REACH Unaffected).

Q: Are there mechanical compatibility issues when substituting these parts?

A: Yes. Lead spacing remains constant at 0.394" (10.00mm) across all three components, ensuring PCB footprint compatibility. However, physical dimensions vary:

• SLP102M080A1P3: 0.866" diameter, 0.984" height
• SLP102M100A3P3: 0.866" diameter, 1.181" height
• 381LX102M080J012: 0.984" diameter, 1.063" height

The SLP102M100A3P3 requires 0.197" additional height clearance. The 381LX102M080J012 requires 0.118" additional diameter clearance. Verify available mechanical envelope in the application before component selection.

Q: Why is the SLP102M100A3P3 preferred over the 381LX102M080J012?

A: The SLP102M100A3P3 is preferred because it maintains Active product status, ensuring long-term availability and supply chain stability. The component also exhibits lower ESR (265 mOhm versus unspecified for the 381LX102M080J012) and higher ripple current capacity. The 381LX102M080J012 is classified as Obsolete, making it unsuitable for new designs despite current inventory availability.

Q: Can these capacitors be used interchangeably in high-ripple-current applications?

A: Ripple current capacity differs among the three components. The SLP102M080A1P3 supports 1.19 A @ 120 Hz and 1.49 A @ 20 kHz. The SLP102M100A3P3 supports 1.47 A @ 120 Hz and 1.84 A @ 20 kHz. The 381LX102M080J012 supports 1.3 A @ 120 Hz and 1.5 A @ 20 kHz. Application ripple current requirements must not exceed the selected component's rated capacity. The SLP102M100A3P3 provides the highest ripple current margin.

Q: Are all three components RoHS and REACH compliant?

A: Yes. All three components are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the significance of the ±20% tolerance specification?

A: The ±20% tolerance indicates that actual capacitance values may range from 800 µF to 1200 µF. This tolerance applies equally to all three components. Applications requiring tighter capacitance tolerance must specify alternative component families with lower tolerance ratings (±10%, ±5%, or ±2%).
