Key Parameters

Substitute Part Grouping Explanation

Substitution of aluminum electrolytic capacitors is determined by strict alignment of electrical and mechanical parameters. The primary substitution criteria for the SLP472M080H5P3 are:

Critical Parameters (Must Match):

• Capacitance: 4700 µF
• Tolerance: ±20%
• Voltage Rating: 80 V (minimum)
• Lead Spacing: 0.394" (10.00 mm)
• Mounting Type: Through Hole
• Package Type: Radial, Can - Snap-In

Secondary Parameters (Allowable Variation):

• ESR: Variation acceptable within general-purpose application limits
• Ripple Current: Application-dependent; lower values represent more conservative designs
• Physical Dimensions (Diameter / Height): Variation acceptable if board-mounted space permits
• Lifetime: All candidates maintain 3000 Hrs @ 105°C minimum

The two identified substitute parts maintain these critical parameters while permitting variation in physical envelope and performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

SLP472M080H5P3 (Original Part) All applications requiring the original electrical and mechanical specifications. Active product status confirms full manufacturing support and compliance certifications. ROHS3 compliance and REACH unaffected status confirm regulatory alignment.

381LX472M080K052 (Voltage-Equivalent Substitute) Electrical equivalence maintained at 80 V rated voltage and 4700 µF capacitance. Lead spacing and mounting type match original specification. Physical envelope differs: diameter reduced to 1.181" (30.00 mm) with height increased to 2.047" (52.00 mm). This configuration suits applications where reduced radial footprint is beneficial and vertical space permits. ESR data not provided; verify ripple current performance meets application requirements. Active product status and full compliance certifications confirmed.

SLP472M100H4P3 (Voltage-Upgraded Substitute) Higher voltage rating (100 V vs. 80 V) with identical 4700 µF capacitance and ±20% tolerance. Lead spacing matches original specification. Same diameter as original (1.378" / 35.00 mm) with intermediate height (1.772" / 45.00 mm). Improved ESR specification (56 mOhm vs. 71 mOhm) provides lower series resistance. This configuration suits applications requiring voltage margin above the original 80 V specification or where lower ESR improves performance. Active product status and full compliance certifications confirmed.

Frequently Asked Questions (FAQ)

Q: Can 381LX472M080K052 be used as a direct replacement for SLP472M080H5P3?

A: Electrical substitution is valid for identical voltage rating (80 V) and capacitance (4700 µF). Physical envelope change requires board-space verification. The reduced diameter (30.00 mm vs. 35.00 mm) reduces radial footprint, while the increased height (52.00 mm vs. 35.00 mm) requires vertical clearance confirmation. Lead spacing remains unchanged at 0.394" (10.00 mm).

Q: When should SLP472M100H4P3 be selected over the original SLP472M080H5P3?

A: Selection of the 100 V rated variant is appropriate when circuit design requires voltage margin beyond the original 80 V specification or when the improved ESR characteristic (56 mOhm vs. 71 mOhm) benefits ripple current performance. The higher voltage rating does not prevent use in 80 V circuits; it provides additional operational safety margin.

Q: Are all three parts compatible with identical PCB mounting layouts?

A: Lead spacing (0.394" / 10.00 mm) is identical across all three parts, ensuring through-hole mounting hole pattern compatibility. Physical diameter and height variations require board space validation. SLP472M080H5P3 and SLP472M100H4P3 share identical radial diameter (35.00 mm), while 381LX472M080K052 has reduced diameter (30.00 mm). Height differences affect available vertical clearance above the PCB.

Q: What is the significance of ESR variation among these parts?

A: Equivalent Series Resistance (ESR) affects ripple current handling and heat generation. SLP472M100H4P3 provides lower ESR (56 mOhm) compared to SLP472M080H5P3 (71 mOhm), improving thermal performance in high-ripple-current applications. ESR specification absence for 381LX472M080K052 requires application-specific ripple current comparison using provided 120 Hz and 20 kHz values.

Q: Are all substitute parts RoHS and REACH compliant?

A: All three parts—SLP472M080H5P3, 381LX472M080K052, and SLP472M100H4P3—carry ROHS3 Compliant status and REACH Unaffected designation, confirming regulatory compliance across all substitution options.
