Substitute Part Grouping Explanation

Substitution eligibility for the B41252B7828M is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 8200 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: 35 V (exact match required)
• Polarization: Polar (exact match required)
• Lead Spacing: 0.394" (10.00 mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can - Snap-In (exact match required)
• Operating Temperature Range: -40°C ~ 105°C (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The substitute part LGU1V822MELA meets all mandatory electrical and mechanical parameters. Variations in lifetime rating (3000 Hrs @ 105°C versus 2000 Hrs @ 105°C) and ripple current specifications represent performance enhancements that do not compromise compatibility or circuit function.

Parameter Comparison

Engineering Selection Recommendations

Both the B41252B7828M and LGU1V822MELA are active production components with ROHS3 compliance and REACH unaffected status. The LGU1V822MELA substitute offers extended lifetime performance at 3000 Hrs @ 105°C compared to the primary part's 2000 Hrs @ 105°C rating. Both components maintain identical electrical specifications (8200 µF, ±20%, 35 V) and mechanical compatibility (through-hole, radial snap-in package, 10.00 mm lead spacing, 42.00 mm maximum height). Selection between these parts should be based on component availability and application-specific lifetime requirements.

Frequently Asked Questions (FAQ)

Q: Can the LGU1V822MELA directly replace the B41252B7828M in existing circuit designs?

A: Yes. Both components share identical capacitance (8200 µF), tolerance (±20%), voltage rating (35 V), operating temperature range (-40°C ~ 105°C), lead spacing (10.00 mm), and snap-in radial package configuration. PCB layout and circuit connections require no modification.

Q: What is the significance of the different lifetime ratings?

A: The B41252B7828M is rated for 2000 Hrs @ 105°C, while the LGU1V822MELA is rated for 3000 Hrs @ 105°C. This difference reflects manufacturer-specific design and testing protocols. Both ratings are valid for their respective components. Application requirements determine which lifetime specification is appropriate.

Q: Are there dimensional differences between these parts?

A: The can diameter differs slightly: B41252B7828M measures 1.000" (25.40 mm), while LGU1V822MELA measures 0.984" (25.00 mm). Both maintain the same 1.654" (42.00 mm) maximum seated height and 0.394" (10.00 mm) lead spacing. These dimensional variations are within standard manufacturing tolerances for snap-in aluminum electrolytic capacitors and do not affect mechanical compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the B41252B7828M and LGU1V822MELA are ROHS3 compliant and REACH unaffected, with identical ECCN (EAR99) and HTSUS (8532.22.0040) classifications.

Q: What is the difference in ripple current specifications?

A: The B41252B7828M specifies 3.02 A @ 120 Hz ripple current. The LGU1V822MELA specifies 2.73 A @ 120 Hz and 3.1395 A @ 50 kHz. These values reflect manufacturer-specific measurement conditions and design characteristics. Both components are suitable for general-purpose applications within their rated specifications.
