Substitute Part Grouping Explanation

Substitution eligibility is determined by strict parameter matching across electrical and mechanical specifications. The following criteria establish valid substitution:

Mandatory Matching Parameters:

Capacitance: 2.2 µF (exact match required)
Voltage Rating: 400 V minimum (equal or higher acceptable)
Tolerance: ±20% (exact match required)
Lead Spacing: 0.197" (5.00 mm) (exact match required)
Package Type: Radial, Can (exact match required)
Mounting Type: Through Hole (exact match required)
Polarization: Polar (exact match required)

Performance Parameters (Enhancement Acceptable):

Operating Temperature Range: -40°C ~ 85°C minimum (extended range acceptable)
Lifetime @ Temperature: 2000 Hrs @ 85°C minimum (extended life acceptable)

Substitute parts are classified into two categories: direct equivalents maintaining identical electrical specifications, and upgrades providing enhanced performance characteristics while maintaining full mechanical and electrical compatibility.

Engineering Selection Recommendations

Direct Equivalent (UVR2G2R2MPD): The UVR2G2R2MPD maintains identical electrical and mechanical specifications to the main part while offering ROHS3 compliance. However, this part carries "Not For New Designs" status, limiting its suitability for new development. It serves as a transitional option for existing inventory management only.

Upgrade Options (MAL214267228E3, MAL215256228E3, MAL215266228E3): All three Vishay alternatives are classified as active products with ROHS3 compliance, making them suitable for new designs. These parts provide enhanced performance through extended operating temperature ranges (-40°C ~ 105°C) and increased lifetime ratings (2500-3000 Hrs @ 105°C). The MAL215256228E3 and MAL215266228E3 carry AEC-Q200 automotive qualification, appropriate for applications requiring automotive-grade reliability. The MAL214267228E3 offers the highest voltage rating at 450 V, providing additional design margin in high-voltage applications.

All substitute parts maintain mechanical compatibility with the original design through identical lead spacing, package type, and mounting configuration.

Frequently Asked Questions (FAQ)

Q: Can UVR2G2R2MPD be used as a direct replacement for UVR2G2R2MPA?

A: Yes, UVR2G2R2MPD is electrically and mechanically identical to the main part. However, it carries "Not For New Designs" status. Use this part only for legacy system support or existing inventory continuation.

Q: What are the advantages of upgrading to MAL215256228E3 or MAL215266228E3?

A: These parts provide 50% longer operational lifetime (3000 Hrs @ 105°C vs. 2000 Hrs @ 85°C), extended operating temperature range to 105°C, and AEC-Q200 automotive qualification. They are active products with full ROHS3 compliance, making them suitable for new designs.

Q: Is MAL214267228E3 compatible with the original circuit design?

A: Yes. MAL214267228E3 maintains identical capacitance, tolerance, lead spacing, and package configuration. The 450 V rating exceeds the 400 V requirement, providing additional voltage margin. Operating temperature extends to 105°C with 2500 Hrs lifetime at that temperature.

Q: Will the substitute parts fit the existing PCB layout?

A: Yes. All substitute parts maintain the 0.197" (5.00 mm) lead spacing and 0.394" (10.00 mm) diameter. The Vishay alternatives have slightly reduced height (0.531" vs. 0.551"), which presents no compatibility issues for through-hole mounting.

Q: Which substitute part should be selected for new designs?

A: For general-purpose applications, MAL214267228E3 provides the highest voltage rating and active product status. For automotive applications, MAL215256228E3 or MAL215266228E3 are required due to AEC-Q200 qualification. All three are ROHS3 compliant and suitable for new designs.

Q: Are there any electrical performance differences between the substitute parts?

A: All parts maintain identical capacitance (2.2 µF) and tolerance (±20%). Ripple current specifications vary slightly: MAL214267228E3 specifies 48 mA @ 100 Hz, while the main part specifies 45 mA @ 120 Hz. These differences reflect measurement methodology variations and do not affect circuit compatibility.
