Substitute Part Grouping Explanation

Substitution of the UVR2W2R2MPD is determined by strict equivalence in the following parameters:

Capacitance: 2.2 µF (exact match required)
Voltage Rating: 450 V (exact match required)
Tolerance: ±20% (exact match required)
Package Type: Radial, Can (exact match required)
Mounting Type: Through Hole (exact match required)
Lead Spacing: 0.197" (5.00 mm) (exact match required)
Polarization: Polar (exact match required)

Substitute parts are categorized as follows:

Direct Equivalents: Parts with identical electrical and mechanical specifications, differing only in manufacturer and series designation.

Upgraded Substitutes: Parts meeting all core parameters with enhanced thermal performance (higher temperature ratings or extended lifetime hours), suitable for applications requiring improved reliability.

Similar Substitutes: Parts with matching core parameters but minor variations in height or thermal characteristics, compatible with the original application.

Engineering Selection Recommendations

For Direct Replacement (Same Thermal Profile): Select ECA-2WM2R2, ECA-2WM2R2B, or ESMG451ELL2R2MJC5S when the original 2000-hour lifetime at 85°C specification is sufficient and active product status is required. These parts maintain identical thermal and electrical characteristics while offering current manufacturing support.

For Enhanced Reliability (Upgraded Thermal Performance): Select 450BXC2.2MEFC10X12.5 (Rubycon) for applications requiring extended operational life, offering 8000 hours at 105°C. Select ECA-2WHG2R2 (Panasonic) or ESH225M450AH1AA (KEMET) for 2000-hour lifetime at the elevated 105°C temperature rating. Select MAL214267228E3 (Vishay) for 2500-hour lifetime at 105°C with extended operating temperature range to -40°C.

For Direct Equivalent (Same Specifications): Select 225CKE450M (Cornell Dubilier / Illinois Capacitor) as a direct electrical and mechanical equivalent with active product status and improved thermal rating to 105°C.

All substitute parts are ROHS3 compliant and suitable for through-hole mounting applications with 0.197" (5.00 mm) lead spacing and 0.394" (10.00 mm) diameter specifications.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different height? A: Height variations within the radial can package are acceptable if the PCB layout accommodates the dimensional change. The UVR2W2R2MPD is 0.551" (14.00 mm) maximum height. Substitutes range from 0.531" to 0.591" (14.60 mm to 15.00 mm). Verify clearance in your specific application before selection.

Q: What is the difference between direct equivalents and upgraded substitutes? A: Direct equivalents maintain the original 2000-hour lifetime at 85°C specification. Upgraded substitutes offer extended lifetime hours (2500 to 8000 hours) or higher temperature ratings (105°C), providing improved reliability for demanding applications.

Q: Are all substitute parts ROHS3 compliant? A: Yes, all listed substitute parts are ROHS3 compliant, matching the original UVR2W2R2MPD compliance status.

Q: Does the operating temperature range affect substitution? A: Operating temperature range is a selection criterion. The original part operates from -25°C to 85°C. Substitutes with -25°C to 105°C range offer broader thermal operation. MAL214267228E3 extends the lower limit to -40°C for cold-environment applications.

Q: What is the significance of the "Not For New Designs" status? A: This designation indicates the UVR2W2R2MPD is obsolete and no longer recommended for new product development. Active substitute parts from current manufacturers ensure long-term availability and manufacturing support.

Q: Can I substitute based on capacitance and voltage alone? A: No. All parameters listed in the Key Parameters section must match exactly: capacitance, voltage, tolerance, package type, mounting type, lead spacing, and polarization. Deviations in any parameter may result in incompatibility.

Q: What packaging options are available? A: Most substitutes are supplied in Bulk packaging. ECA-2WM2R2B is available in Cut Tape (CT) packaging for automated assembly processes. Verify packaging requirements for your procurement and assembly workflow.
