Engineering Selection Recommendations

Primary Selection: SLP473M016E9P3

The SLP473M016E9P3 is the specified component and should be used when available. This part carries Active product status, full RoHS3 compliance, and REACH Unaffected certification. Current inventory availability is 681 pieces.

Substitute Selection: 381LX473M016A452

The 381LX473M016A452 is a direct electrical equivalent with identical capacitance, voltage rating, tolerance, operating temperature range, and lifetime specifications. Both parts are manufactured by Cornell Dubilier Electronics and maintain equivalent compliance certifications.

Physical dimensions differ between the two parts. The 381LX473M016A452 has a larger diameter (1.378" vs 1.181") but shorter height (1.850" vs 1.969"). PCB layout and mounting clearance must be verified before substitution to ensure mechanical fit within the application enclosure.

The 381LX473M016A452 carries Active product status with higher current inventory availability (3090 pieces), providing supply chain advantage.

Both parts are suitable for general purpose applications across the specified operating temperature range with equivalent reliability ratings.

Frequently Asked Questions (FAQ)

Q: Can the 381LX473M016A452 be used as a direct replacement for the SLP473M016E9P3?

A: The 381LX473M016A452 is electrically equivalent across all critical parameters: capacitance, voltage rating, tolerance, operating temperature, and lifetime specifications. Both parts are RoHS3 compliant and REACH Unaffected. However, physical dimensions differ. The substitute part has a larger diameter (35.00mm vs 30.00mm) and shorter height (47.00mm vs 50.00mm). PCB layout verification is required to confirm mechanical fit before substitution.

Q: What are the key electrical parameters that determine substitution eligibility?

A: Substitution eligibility requires exact matching of: capacitance value (47000 µF), voltage rating (16 V), tolerance (±20%), operating temperature range (-40°C to 105°C minimum), and lifetime rating (3000 Hrs @ 105°C minimum). Both parts meet these criteria.

Q: Are there differences in ripple current handling between these parts?

A: The 381LX473M016A452 exhibits higher ripple current capacity at 120 Hz (5.5 A vs 5.27 A) but lower capacity at 20 kHz (6.3 A vs 6.59 A). Application-specific ripple current requirements must be evaluated against the frequency spectrum of the circuit.

Q: Do both parts have identical compliance certifications?

A: Both parts carry RoHS3 Compliant status, REACH Unaffected status, and Moisture Sensitivity Level 1 (Unlimited). Compliance certifications are equivalent.

Q: What is the lead spacing for both parts?

A: Both parts have identical lead spacing of 0.394" (10.00mm), ensuring PCB footprint compatibility at the pin level.

Q: Are both parts available in the same packaging format?

A: Both parts are supplied in Bulk packaging as Radial, Can - Snap-In through-hole components with identical polarization (Polar).
