B43540A2188M82 Equivalent & Substitute Parts

Part Overview

The B43540A2188M82 is an 1800 µF, 200 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by EPCOS - TDK Electronics. This component is designed for general purpose applications requiring high capacitance and voltage ratings with extended operational lifetime. The part is currently active and available in original packaging with 274,082 units in stock.

Substitute parts become necessary when the original packaging format (tape and reel) is unavailable or when procurement from alternative inventory sources is required. The B43540A2188M000 variant offers identical electrical performance in bulk packaging, making it suitable for applications where packaging format flexibility is acceptable.

Substitute Part Grouping Explanation

Substitution eligibility for the B43540A2188M82 is determined by strict equivalence across the following critical parameters:

• Capacitance: 1800 µF (exact match required)
• Voltage Rating: 200 V (exact match required)
• Tolerance: ±20% (exact match required)
• ESR @ 100Hz: 50 mOhm (exact match required)
• Lifetime @ 85°C: 10000 Hrs (exact match required)
• Operating Temperature: -40°C to 85°C (exact match required)
• Ripple Current @ 100Hz: 5.3 A (exact match required)
• Lead Spacing: 10.00 mm (exact match required)
• Diameter: 35.00 mm (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Type: Radial, Can - Snap-In (exact match required)

The B43540A2188M000 meets all substitution criteria with identical electrical and mechanical specifications. The only difference is packaging format (bulk versus tape and reel), which does not affect functional performance in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

The B43540A2188M000 is a direct functional equivalent to the B43540A2188M82 with full electrical and mechanical compatibility. Both parts are ROHS3 compliant, REACH unaffected, and carry identical reliability ratings.

Selection between these parts should be based on:

• Product Status: The B43540A2188M82 is active and recommended for new designs. The B43540A2188M000 carries a "Not For New Designs" status, indicating it is maintained for legacy support only.
• Packaging Requirements: The B43540A2188M82 is supplied in tape and reel format suitable for automated assembly. The B43540A2188M000 is supplied in bulk packaging, appropriate for manual assembly or low-volume applications.
• Inventory Availability: The B43540A2188M82 has 274,082 units in stock. The B43540A2188M000 has 1,028 units in stock.

For new circuit designs, the B43540A2188M82 is the preferred selection. The B43540A2188M000 is suitable only when the original part is unavailable and legacy design support is acceptable.

Frequently Asked Questions (FAQ)

Q: Can B43540A2188M000 be used as a direct replacement for B43540A2188M82 in existing assemblies?

A: Yes. Both parts have identical electrical specifications, mechanical dimensions, and mounting characteristics. The only difference is packaging format. Functional performance in the circuit is equivalent.

Q: What is the significance of the "Not For New Designs" status on B43540A2188M000?

A: This designation indicates the part is maintained for legacy applications and existing inventory support only. EPCOS - TDK Electronics recommends using B43540A2188M82 for all new circuit designs.

Q: Are there dimensional differences between these parts?

A: The seated height differs by 0.2 mm (B43540A2188M82: 47.20 mm maximum; B43540A2188M000: 47.00 mm maximum). This variation is within standard manufacturing tolerance and does not affect PCB layout or mechanical clearance in typical applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited).

Q: What is the difference between tape and reel packaging and bulk packaging?

A: Tape and reel packaging is designed for automated pick-and-place assembly equipment. Bulk packaging is supplied loose or in trays, suitable for manual assembly or low-volume production. Electrical and mechanical performance is identical.

Q: Can B43540A2188M000 be used in high-reliability applications?

A: Both parts carry identical lifetime ratings (10,000 hours @ 85°C) and operating temperature ranges (-40°C to 85°C). Reliability performance is equivalent. However, the "Not For New Designs" status should be considered for mission-critical applications where long-term manufacturer support is required.
