B43252F2277M Equivalent & Substitute Parts

Part Overview

The B43252F2277M is a 270 µF, 250 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by EPCOS - TDK Electronics. This component is rated for 2000 hours at 105°C and is designed for general purpose applications requiring through-hole mounting. The part is Active status and ROHS3 compliant.

Equivalent and substitute parts are identified when they maintain the same electrical specifications (capacitance, voltage rating, tolerance, and polarization) and mechanical compatibility (package type, lead spacing, mounting configuration). Alternative manufacturers and upgraded performance variants are listed below.

Substitute Part Grouping Explanation

Substitution eligibility for the B43252F2277M is determined by strict equivalence in the following parameters:

• Electrical Match: Capacitance (270 µF), voltage rating (250 V), tolerance (±20%), and polarization (polar) must be identical
• Mechanical Compatibility: Package type (radial, can snap-in), lead spacing (10.00 mm), and through-hole mounting must be maintained
• Operating Range: Temperature range must encompass or match -40°C to 105°C

Two substitute parts meet these criteria:

1. B43547E2277M000 (EPCOS - TDK Electronics): Upgraded variant within the same manufacturer family with improved lifetime (3000 hrs @ 105°C) and lower ESR (260 mOhm @ 100 Hz)
2. LGR2E271MELA30 (Nichicon): Cross-manufacturer equivalent with extended lifetime (10000 hrs @ 105°C)

Parameter Comparison

Engineering Selection Recommendations

All three parts are Active status and ROHS3 compliant, meeting current regulatory requirements. Selection between them depends on application lifetime requirements:

• B43252F2277M: Baseline specification for applications with 2000-hour service life at 105°C
• B43547E2277M000: Recommended for applications requiring extended reliability within the EPCOS product family, offering 50% longer lifetime and measurable ESR specification
• LGR2E271MELA30: Recommended for applications requiring maximum service life (10000 hours @ 105°C), providing five-fold lifetime extension over the original part

All parts maintain identical electrical and mechanical compatibility, allowing direct substitution without circuit redesign or PCB modification.

Frequently Asked Questions (FAQ)

Q: Can B43547E2277M000 be used as a direct replacement for B43252F2277M?

A: Yes. Both parts share identical capacitance (270 µF), voltage rating (250 V), tolerance (±20%), package type (radial snap-in), lead spacing (10.00 mm), and operating temperature range (-40°C to 105°C). The B43547E2277M000 offers improved lifetime (3000 hrs vs. 2000 hrs @ 105°C) and specified ESR characteristics.

Q: What is the primary difference between the EPCOS B43547E2277M000 and Nichicon LGR2E271MELA30?

A: Both are electrically and mechanically equivalent to the B43252F2277M. The key difference is manufacturer and lifetime rating. The Nichicon LGR2E271MELA30 provides 10000-hour lifetime at 105°C compared to 3000 hours for the EPCOS upgrade, representing a significant reliability advantage for long-term applications.

Q: Are there any package or mounting differences between these three parts?

A: No. All three parts use identical radial, can snap-in packaging with 10.00 mm lead spacing and through-hole mounting configuration. No PCB layout changes are required for substitution.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Moisture sensitivity level is 1 (unlimited) for B43252F2277M and B43547E2277M000; the Nichicon part lists MSL as not applicable.

Q: Which part should be selected for new designs?

A: Selection is based on required service life. For new designs, the Nichicon LGR2E271MELA30 offers the longest operational lifetime (10000 hrs @ 105°C) while maintaining full electrical and mechanical compatibility. The EPCOS B43547E2277M000 provides a mid-range option with improved performance over the original B43252F2277M.
