Substitute Part Grouping Explanation

Substitution eligibility for the B43508B2188M80 is determined by strict alignment of the following parameters:

• Capacitance value: 1800 µF (exact match required)
• Voltage rating: 200 V (exact match required)
• Tolerance: ±20% (exact match required)
• Operating temperature range: -40°C ~ 105°C (exact match required)
• Lifetime specification: 3000 Hrs @ 105°C (exact match required)
• Polarization: Polar (exact match required)
• Package type: Radial, Can - Snap-In (exact match required)
• Lead spacing: 0.394" (10.00mm) (exact match required)
• Physical dimensions: 1.378" Dia (35.00mm) (exact match required)
• Mounting type: Through Hole (exact match required)
• Compliance: ROHS3 Compliant (exact match required)

The identified substitute parts B43509B2188M000 and LGN2D182MELC40 satisfy all mandatory electrical and mechanical parameters. Variations in ESR, impedance, and ripple current specifications remain within acceptable operational ranges for general purpose applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—B43508B2188M80, B43509B2188M000, and LGN2D182MELC40—maintain Active product status and are ROHS3 Compliant, confirming current manufacturing availability and regulatory compliance. The B43509B2188M000 is manufactured by the same supplier (EPCOS - TDK Electronics) as the main part, differing only in series designation and minor variations in ESR and impedance characteristics. The LGN2D182MELC40 from Nichicon provides an alternative from a different manufacturer while maintaining identical electrical ratings and physical form factor. Selection between these parts depends on supply chain availability, inventory status, and specific application requirements regarding ESR performance.

Frequently Asked Questions (FAQ)

Q: Can B43509B2188M000 be used as a direct replacement for B43508B2188M80?

A: Yes. Both parts share identical capacitance (1800 µF), voltage rating (200 V), tolerance (±20%), operating temperature range (-40°C ~ 105°C), lifetime specification (3000 Hrs @ 105°C), and physical dimensions. The primary difference is ESR at 100 Hz (80 mOhm vs. 65 mOhm), which remains within acceptable operational parameters for general purpose applications.

Q: What are the mechanical compatibility considerations?

A: All three parts feature identical lead spacing (0.394" / 10.00mm), diameter (1.378" / 35.00mm), and snap-in package configuration. Height variations are minimal (B43508B2188M80 at 1.661" vs. B43509B2188M000 and LGN2D182MELC40 at 1.654"), presenting no practical mounting or clearance issues in standard PCB layouts.

Q: Does manufacturer selection affect performance?

A: Both EPCOS - TDK Electronics and Nichicon are established manufacturers meeting ROHS3 compliance and REACH requirements. Selection is based on supply availability and specific application ripple current demands. The LGN2D182MELC40 provides higher ripple current capability (3.08 A @ 120 Hz and 4.62 A @ 50 kHz) compared to the main part (2.54 A @ 100 Hz).

Q: Are there any compliance or certification differences?

A: All three parts are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99 with identical HTSUS code 8532.22.0040. No compliance barriers exist for substitution.

Q: What inventory considerations apply?

A: B43508B2188M80 has 274,082 pcs in stock, B43509B2188M000 has 1,345 pcs, and LGN2D182MELC40 has 273,982 pcs. Availability varies significantly; selection should account for project timeline and quantity requirements.
