Substitute Part Grouping Explanation

Substitute parts for the 478LMB063M2CH are classified based on strict electrical and mechanical parameter matching:

Substitution Criteria:

• Capacitance: 4700 µF (exact match required)
• Voltage Rating: 63 V (exact match required)
• Tolerance: ±20% (exact match required)
• Operating Temperature: -40°C to 105°C (exact match required)
• Polarization: Polar (exact match required)
• 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)
• Physical Dimensions: 0.984" Dia × 2.047" Height (exact match required)
• Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

Substitute Parts Identified:

1. LGY1J472MELA50 (Nichicon) - Upgrade substitute with extended lifetime rating
2. 381LX472M063J052 (Cornell Dubilier Electronics) - Parametric equivalent from same manufacturer family

Both substitute parts meet all mandatory electrical and mechanical parameters. Differences exist only in performance characteristics such as lifetime rating and ripple current specifications, which are provided in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

478LMB063M2CH (Main Part): Use as primary selection when standard lifetime requirements of 3000 hours at 105°C are acceptable. This part is manufactured by Cornell Dubilier / Illinois Capacitor and maintains active production status with robust inventory availability. All compliance certifications (ROHS3, REACH Unaffected) are current.

LGY1J472MELA50 (Nichicon - Upgrade Substitute): Select this substitute when extended operational lifetime of 5000 hours at 105°C is required. This part offers superior reliability margin for applications with extended service life expectations. Manufactured by Nichicon with active product status and adequate inventory. All compliance certifications match the main part. Ripple current specifications are lower at both low and high frequencies, which may be a consideration in high-ripple-current applications.

381LX472M063J052 (Cornell Dubilier Electronics - Parametric Equivalent): Select this substitute when maintaining the same manufacturer family is preferred or when supply of the main part is constrained. This part shares identical lifetime rating (3000 hours at 105°C) with the main part and offers comparable ripple current performance. Manufactured by Cornell Dubilier Electronics with active product status and highest current inventory (1122 units). All compliance certifications are current.

All three parts are suitable for direct substitution in general-purpose applications requiring 4700 µF, 63 V aluminum electrolytic capacitors in radial snap-in package format. Selection between them depends on lifetime requirements, manufacturer preference, and ripple current performance needs specific to the application circuit.

Frequently Asked Questions (FAQ)

Q: Can LGY1J472MELA50 be used as a direct replacement for 478LMB063M2CH?

A: Yes. Both parts share identical electrical specifications (4700 µF, 63 V, ±20% tolerance), operating temperature range (-40°C to 105°C), and mechanical dimensions (0.984" diameter, 2.047" height, 10.00mm lead spacing). Both are radial, can-style snap-in through-hole components with ROHS3 compliance. The primary difference is extended lifetime (5000 hours vs. 3000 hours at 105°C), which represents an upgrade in reliability margin.

Q: What is the difference between the two substitute parts?

A: LGY1J472MELA50 (Nichicon) offers 5000-hour lifetime at 105°C compared to 3000 hours for both the main part and 381LX472M063J052 (Cornell Dubilier Electronics). The 381LX part maintains identical lifetime to the main part but is from a different Cornell Dubilier product line. Ripple current specifications vary slightly between parts due to different internal construction, but all three parts meet the same electrical and mechanical interface requirements.

Q: Are there any physical compatibility issues when substituting these parts?

A: No. All three parts have identical lead spacing (0.394" / 10.00mm), diameter (0.984" / 25.00mm), and maximum seated height (2.047" / 52.00mm). They are all radial, can-style snap-in packages designed for through-hole mounting. PCB footprints and mounting hardware compatibility are identical.

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

A: Yes. All three parts are ROHS3 Compliant and REACH Unaffected. They share identical ECCN (EAR99) and HTSUS (8532.22.0040) classifications. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for the main part and 381LX472M063J052; Nichicon's LGY1J472MELA50 lists MSL as Not Applicable.

Q: Which part should be selected for a new design?

A: For new designs, LGY1J472MELA50 is recommended when design life exceeds 3000 hours at 105°C, as it provides extended reliability margin. For applications with standard 3000-hour lifetime requirements, either the main part (478LMB063M2CH) or the parametric equivalent (381LX472M063J052) are suitable. Inventory availability and manufacturer preference may influence final selection.

Q: Can these parts be used interchangeably in existing assemblies?

A: Yes. All three parts are direct mechanical and electrical substitutes. Existing PCB designs, mounting fixtures, and assembly processes require no modification. The snap-in package format ensures consistent installation across all three part numbers.
