Substitute Part Grouping Explanation

Substitute parts for the 477LBB160M2CC are classified into two categories based on electrical and mechanical compatibility:

Direct Equivalent (Same Voltage Rating): The SLPX471M160C1P3 from Cornell Dubilier Electronics (CDE) maintains the same 470 µF capacitance, 160 V voltage rating, ±20% tolerance, and 3000-hour lifetime at 85°C. This part shares identical lead spacing (10.00 mm), diameter (25.00 mm), and through-hole mounting configuration. The primary difference is ESR at 120 Hz (423 mOhm versus 352.74 mOhm) and height (25.00 mm versus 27.00 mm maximum seated height). Both parts are ROHS3 compliant and REACH unaffected.

Upgrade Substitute (Higher Voltage Rating): The 250USG470MEFCSN25X25 from Rubycon is a 470 µF capacitor rated at 250 V, providing increased voltage margin over the original 160 V specification. This part maintains identical capacitance, tolerance, lifetime, lead spacing, and diameter. Height remains at 27.00 mm maximum seated height. The higher voltage rating permits use in applications where circuit voltage may exceed 160 V. This part is ROHS3 compliant and REACH unaffected.

Key Parameters Determining Substitution:

• Capacitance: 470 µF (fixed)
• Tolerance: ±20% (fixed)
• Lifetime: 3000 Hrs @ 85°C (fixed)
• Package: Radial, Can - Snap-In (fixed)
• Lead Spacing: 10.00 mm (fixed)
• Diameter: 25.00 mm (fixed)
• Mounting: Through Hole (fixed)
• Voltage Rating: 160 V (direct equivalent) or 250 V (upgrade)

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection (SLPX471M160C1P3): The SLPX471M160C1P3 is suitable for direct substitution when the 160 V voltage rating requirement is fixed and inventory of the 477LBB160M2CC is unavailable. Both parts maintain ROHS3 compliance and REACH unaffected status. The SLPX series offers higher ripple current capability (1.86 A @ 120 Hz versus 1.74 A), which may provide operational margin in ripple-current-sensitive applications. The 2 mm height reduction (25.00 mm versus 27.00 mm) must be verified against PCB layout constraints and mechanical clearance requirements. ESR difference (423 mOhm versus 352.74 mOhm) should be evaluated in applications where low impedance is critical.

Upgrade Substitute Selection (250USG470MEFCSN25X25): The 250USG470MEFCSN25X25 is appropriate when circuit design permits or requires a higher voltage rating than 160 V. This Rubycon part provides increased voltage margin and higher ripple current ratings (2.11 A @ 120 Hz and 3.165 A @ 10 kHz), making it suitable for applications with elevated voltage stress or higher ripple current demands. ROHS3 compliance and REACH unaffected status are maintained. The part maintains the same 27.00 mm maximum height as the original 477LBB160M2CC, ensuring compatibility with existing mechanical constraints. Selection of this upgrade substitute requires confirmation that the circuit design supports 250 V operation.

Compliance Verification: All three parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for modern electronic equipment. Product status is active for all parts, ensuring continued availability and manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can the SLPX471M160C1P3 be used as a direct replacement for the 477LBB160M2CC?

A: Yes, the SLPX471M160C1P3 is a direct equivalent substitute. Both parts share identical capacitance (470 µF), voltage rating (160 V), tolerance (±20%), lifetime (3000 Hrs @ 85°C), lead spacing (10.00 mm), diameter (25.00 mm), and through-hole mounting configuration. The primary differences are ESR (423 mOhm versus 352.74 mOhm) and seated height (25.00 mm versus 27.00 mm). Verify that the reduced height does not conflict with PCB layout or mechanical clearance requirements.

Q: When should the 250USG470MEFCSN25X25 be selected instead of the direct equivalent?

A: The 250USG470MEFCSN25X25 should be selected when the circuit design permits or requires a voltage rating higher than 160 V. This upgrade substitute provides increased voltage margin and higher ripple current capability. Selection requires confirmation that the circuit operates at or below 250 V and that the higher ripple current ratings align with application requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all three parts—477LBB160M2CC, SLPX471M160C1P3, and 250USG470MEFCSN25X25—are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for modern electronic equipment.

Q: What is the significance of the ESR difference between the main part and the direct equivalent?

A: ESR (Equivalent Series Resistance) affects impedance and heat dissipation. The 477LBB160M2CC has lower ESR (352.74 mOhm @ 120 Hz) compared to the SLPX471M160C1P3 (423 mOhm @ 120 Hz). In applications where low impedance is critical, such as high-frequency filtering or low-noise power supplies, the lower ESR of the main part may be preferred. However, the difference is typically acceptable for general-purpose applications.

Q: Does the height difference between the direct equivalent and main part affect compatibility?

A: The SLPX471M160C1P3 has a maximum seated height of 25.00 mm, compared to 27.00 mm for the 477LBB160M2CC. This 2 mm reduction must be verified against PCB layout, component spacing, and mechanical clearance requirements. If the PCB design accommodates the reduced height, compatibility is maintained. If height is constrained, the upgrade substitute (250USG470MEFCSN25X25) maintains the original 27.00 mm height.

Q: Can the 250USG470MEFCSN25X25 be used in circuits designed for 160 V operation?

A: Yes, the 250USG470MEFCSN25X25 can be used in circuits designed for 160 V operation. The higher voltage rating (250 V) provides additional voltage margin and does not degrade performance at lower voltages. This part is suitable for applications where voltage stress may exceed 160 V or where increased voltage margin is desired for reliability.

Q: What inventory status should be considered when selecting a substitute?

A: The 477LBB160M2CC has 664 pieces in stock, the SLPX471M160C1P3 has 3656 pieces in stock, and the 250USG470MEFCSN25X25 has 1054 pieces in stock. Inventory availability may influence selection when immediate delivery is required.
