478LBA050M2BF Equivalent & Substitute Parts Reference

Part Overview

The 478LBA050M2BF is a 4700 µF, 50 V aluminum electrolytic capacitor manufactured by Cornell Dubilier / Illinois Capacitor in the LBA series. This radial, can-style snap-in capacitor is designed for general-purpose applications with a rated lifetime of 2000 hours at 85°C and an operating temperature range of -40°C to 85°C. The part is ROHS3 compliant and currently active in production with 895 pieces in stock.

Substitute parts are identified when equivalent capacitance, voltage rating, tolerance, package type, and mounting configuration match the original specification, while potentially offering improved performance characteristics such as extended lifetime ratings or lower equivalent series resistance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 478LBA050M2BF is determined by the following mandatory parameters:

Core Electrical Parameters:

• Capacitance: 4700 µF (exact match required)
• Voltage Rating: 50 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)

Core Mechanical Parameters:

• Package Type: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required)
• Size / Dimension: 0.866" Dia (22.00mm) (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• REACH Status: REACH Unaffected (exact match required)

All four substitute parts meet these mandatory criteria. Performance enhancements such as extended lifetime ratings, improved ripple current handling, and reduced equivalent series resistance are secondary considerations that do not disqualify a part from substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are qualified equivalents for the 478LBA050M2BF based on matching core electrical and mechanical parameters, identical voltage and capacitance ratings, and full compliance with ROHS3 and REACH requirements.

SLPX472M050A7P3 (Cornell Dubilier Electronics): This direct manufacturer equivalent offers extended lifetime (3000 hours at 85°C versus 2000 hours), specified ESR of 99 mOhm at 120 Hz, and the highest inventory availability (23,552 pieces). Height is reduced to 1.575" (40.00mm), which may provide board layout advantages in space-constrained applications.

LLS1H472MELZ (Nichicon): This upgrade equivalent provides extended lifetime (3000 hours at 85°C) and maintains identical height (1.654" / 42.00mm) to the original part. Inventory availability is 2,411 pieces.

380LX472M050H032 (Cornell Dubilier Electronics): This similar equivalent offers extended lifetime (3000 hours at 85°C), specified ESR of 110 mOhm at 120 Hz, and the most compact height (1.457" / 37.00mm). Inventory availability is 9,948 pieces.

B41231A6478M000 (EPCOS - TDK Electronics): This parametric equivalent maintains the original 2000-hour lifetime rating and identical height (1.654" / 42.00mm). It provides the highest ripple current rating at 120 Hz (3.83 A). Inventory availability is 4,184 pieces.

All parts are active in production and suitable for direct substitution in general-purpose applications.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the 478LBA050M2BF?

A: Substitution requires exact matching of capacitance (4700 µF), voltage rating (50 V), tolerance (±20%), package type (Radial, Can - Snap-In), mounting type (Through Hole), lead spacing (0.394" / 10.00mm), can diameter (0.866" / 22.00mm), and compliance certifications (ROHS3 Compliant, REACH Unaffected). All four listed parts meet these criteria.

Q: Can I use a substitute part with a different height?

A: Height variations exist among the substitute parts: SLPX472M050A7P3 is 1.575" (40.00mm), 380LX472M050H032 is 1.457" (37.00mm), while LLS1H472MELZ and B41231A6478M000 match the original at 1.654" (42.00mm). Height selection depends on available board space and clearance requirements in your specific application. All heights are within the snap-in can package family and maintain identical lead spacing and diameter.

Q: What is the difference between the substitute parts?

A: The primary differences are manufacturer, series designation, and performance enhancements. SLPX472M050A7P3, LLS1H472MELZ, and 380LX472M050H032 offer extended lifetime (3000 hours at 85°C) compared to the original 2000 hours. B41231A6478M000 maintains the 2000-hour rating but provides higher ripple current capacity. ESR specifications are provided for SLPX472M050A7P3 (99 mOhm) and 380LX472M050H032 (110 mOhm).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All four substitute parts are ROHS3 compliant and REACH unaffected, matching the original part's compliance status.

Q: Which substitute has the best inventory availability?

A: SLPX472M050A7P3 has the highest inventory with 23,552 pieces in stock, followed by 380LX472M050H032 with 9,948 pieces, B41231A6478M000 with 4,184 pieces, and LLS1H472MELZ with 2,411 pieces.

Q: Can I mix different substitute parts in the same circuit?

A: All substitute parts are electrically equivalent for the specified parameters (capacitance, voltage, tolerance, operating temperature range). However, physical height differences may affect board layout consistency. Verify that your PCB layout accommodates the specific height of each part if mixing is necessary.
