Operating Temperature Range: -40°C to 85°C (exact match required)
Lifetime @ 85°C: 10,000 Hrs (exact match required)
RoHS Status: ROHS3 Compliant (exact match required)

Secondary Electrical Parameters (Allowable Variation):

ESR @ 100 Hz: 880 mOhm (B43501 series) or 710 mOhm (B43540 series) - both acceptable
Ripple Current @ 100 Hz: 1.1 A (B43501 series) or 1.29 A (B43540 series) - both acceptable
Impedance: 1.07 Ohms (B43501 series) or 1.03 Ohms (B43540 series) - both acceptable

Substitutes are classified into two categories:

Direct Manufacturer Substitutes (B43540 Series): Parts with improved electrical performance (lower ESR, higher ripple current capacity) while maintaining all primary matching criteria. These represent active production alternatives with enhanced specifications.

Parametric Equivalents (B43501 and B43540 Series): Parts with identical or equivalent electrical characteristics across all critical parameters, differing only in manufacturing date codes or minor packaging variations.

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance): Select from the B43501 series parametric equivalents: B43501C5157M60, B43501C5157M67, B43501C5157M80, or B43501C5157M87. These parts maintain the original 880 mOhm ESR and 1.1 A ripple current specifications while offering active product status. All are ROHS3 compliant and carry unlimited moisture sensitivity rating (MSL 1).

For Enhanced Performance Substitution: The B43540 series direct substitutes (B43540A5157M80, B43540A5157M82, B43540A5157M87, B43540A5157M, B43540A5157M007, B43540A5157M067) provide improved electrical characteristics with 710 mOhm ESR and 1.29 A ripple current capacity. These represent active production alternatives suitable for applications where lower impedance and higher ripple current handling are beneficial. All maintain identical mechanical compatibility and compliance certifications.

Product Status Consideration: The original B43501C5157M000 carries "Not For New Designs" status. All listed substitutes carry "Active" product status, ensuring long-term availability and continued manufacturing support.

Compliance Verification: All substitute parts maintain ROHS3 compliance, REACH unaffected status, and identical ECCN (EAR99) and HTSUS (8532.22.0040) classifications as the original part.

Frequently Asked Questions (FAQ)

Q: Can B43540 series parts directly replace B43501C5157M000 in existing designs?

A: Yes. B43540 series parts meet all primary matching criteria including capacitance, voltage rating, tolerance, package type, lead spacing, mounting type, operating temperature range, and lifetime specifications. The lower ESR (710 mOhm vs. 880 mOhm) and higher ripple current capacity (1.29 A vs. 1.1 A) represent performance improvements compatible with the original application requirements.

Q: What is the difference between the date code suffixes in B43501 and B43540 part numbers?

A: The suffixes (M60, M67, M80, M87, M007, M067) represent manufacturing date codes and do not affect electrical or mechanical specifications. Parts with identical prefixes and capacitance ratings are functionally equivalent.

Q: Are all substitute parts physically interchangeable?

A: Yes. All substitute parts share identical lead spacing (10.00 mm), package type (Radial, Can - Snap-In), and mounting type (Through Hole). Maximum seated height varies slightly between B43501 series (37.00 mm) and B43540 series (37.00-37.20 mm), remaining within standard PCB layout tolerances for snap-in capacitor mounting.

Q: Which substitute offers the best long-term availability?

A: All listed substitutes carry "Active" product status from EPCOS - TDK Electronics, ensuring continued manufacturing and supply. The B43540 series represents the current production line for this capacitance and voltage rating, making these parts the preferred choice for new procurement.

Q: Do substitute parts require any circuit design modifications?

A: No. All substitute parts maintain identical electrical ratings (150 µF, 450 V, ±20% tolerance) and operating specifications (-40°C to 85°C, 10,000 Hrs @ 85°C). The improved ESR and ripple current characteristics of B43540 series parts are backward compatible with designs specified for B43501 series performance.
