B43504C2337M67 Equivalent & Substitute Parts

Part Overview

The B43504C2337M67 is a 330 µF, 250 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by EPCOS - TDK Electronics. This component is classified as Active and suitable for general-purpose applications requiring stable capacitance and extended operational life at elevated temperatures. The part features a 3000-hour lifetime rating at 105°C, making it suitable for industrial and power supply applications.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or when design revisions require components with identical electrical and mechanical specifications but different packaging or availability profiles.

Substitute Part Grouping Explanation

Substitution eligibility for the B43504C2337M67 is determined by strict equivalence across the following critical parameters:

• Capacitance value: 330 µF (exact match required)
• Rated voltage: 250 V (exact match required)
• Tolerance: ±20% (exact match required)
• ESR @ 100Hz: 390 mOhm (exact match required)
• Lifetime rating: 3000 Hrs @ 105°C (exact match required)
• Operating temperature range: -40°C ~ 105°C (exact match required)
• Ripple current capability: 1.2 A @ 100Hz (exact match required)
• Package type: Radial, Can - Snap-In (exact match required)
• Mounting configuration: Through Hole (exact match required)
• Lead spacing: 0.394" (10.00 mm) (exact match required)

The B43504C2337M000 meets all electrical and mechanical equivalence criteria and qualifies as a direct parametric substitute. Packaging differs only in distribution format (Bulk vs. standard packaging), which does not affect functional compatibility or board-level integration.

Parameter Comparison

Engineering Selection Recommendations

The B43504C2337M000 is electrically and mechanically equivalent to the B43504C2337M67 across all specified parameters. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications.

The primary distinction is product lifecycle status: B43504C2337M67 is designated Active, while B43504C2337M000 is marked Not For New Designs. For ongoing production and new design implementations, the B43504C2337M67 is the preferred selection. The B43504C2337M000 remains suitable for legacy system maintenance, repair, and field replacement where design changes are not feasible.

Both parts are functionally interchangeable at the board level due to identical lead spacing, package dimensions, and mounting configuration. No circuit modifications or PCB layout adjustments are required when transitioning between these parts.

Frequently Asked Questions (FAQ)

Q: Can B43504C2337M000 be used as a direct replacement for B43504C2337M67 in existing designs?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications. The difference in product status does not affect functional performance or board-level compatibility.

Q: What is the significance of the "Not For New Designs" status on B43504C2337M000?

A: This designation indicates the part is in end-of-life phase and should not be selected for new product development. It remains available for legacy system support and field replacement applications where design continuity is required.

Q: Are there any differences in packaging that affect handling or installation?

A: The primary packaging difference is distribution format (Bulk vs. standard). Both parts use identical through-hole radial snap-in package configuration with 0.394" (10.00 mm) lead spacing and 0.984" (25.00 mm) diameter. Installation procedures and PCB footprints are identical.

Q: Do both parts meet the same compliance and regulatory standards?

A: Yes. Both B43504C2337M67 and B43504C2337M000 are ROHS3 compliant and REACH unaffected, meeting current industrial and commercial regulatory requirements.

Q: What are the critical parameters that must match for substitution eligibility?

A: Capacitance (330 µF), rated voltage (250 V), tolerance (±20%), ESR (390 mOhm @ 100Hz), lifetime rating (3000 Hrs @ 105°C), operating temperature range (-40°C ~ 105°C), ripple current (1.2 A @ 100Hz), and package type (Radial, Can - Snap-In) must all match exactly. Any deviation disqualifies a part as a direct substitute.
