Substitute Part Grouping Explanation

Substitution of the UVR2AR22MDD is determined by the following critical parameters:

• Capacitance Value: 0.22 µF (exact match required)
• Voltage Rating: 100 V (minimum requirement; higher ratings acceptable)
• Polarization: Polar (must match)
• Package Type: Radial, Can (mechanical and electrical compatibility)
• Mounting Type: Through Hole (PCB assembly compatibility)
• Lead Spacing: 0.079" (2.00mm) (footprint compatibility)
• Physical Dimensions: 0.197" Dia (5.00mm) and Height ≤ 0.492" (12.50mm) (board space constraints)
• Operating Temperature Range: -40°C ~ 85°C (functional requirement)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

The UKL2AR22KDD meets all substitution criteria. The primary difference is improved tolerance (±10% versus ±20%), which represents an upgrade in precision without compromising compatibility.

Parameter Comparison

Engineering Selection Recommendations

The UKL2AR22KDD is a direct substitute for the obsolete UVR2AR22MDD. Both parts maintain identical electrical specifications for capacitance, voltage rating, and operating temperature range. The UKL2AR22KDD offers improved tolerance performance (±10% versus ±20%), which enhances circuit precision without introducing compatibility issues.

Both parts are ROHS3 compliant and maintain equivalent mechanical compatibility. The UKL2AR22KDD features a slightly reduced maximum seated height (0.472" versus 0.492"), which provides additional design flexibility for space-constrained applications while remaining within standard through-hole footprint requirements.

Selection between these parts should be based on procurement availability and tolerance requirements for the specific application circuit.

Frequently Asked Questions (FAQ)

Q: Can the UKL2AR22KDD replace the UVR2AR22MDD in existing designs?

A: Yes. The UKL2AR22KDD is mechanically and electrically compatible. Both parts share identical capacitance, voltage rating, polarization, lead spacing, and physical diameter. The substitute features improved tolerance and slightly reduced height, both of which are compatible with existing PCB layouts.

Q: What is the primary difference between these two parts?

A: The UKL2AR22KDD provides tighter tolerance (±10%) compared to the UVR2AR22MDD (±20%). This represents improved precision in capacitance value without affecting electrical performance or mechanical fit.

Q: Are both parts RoHS compliant?

A: Yes. Both the UVR2AR22MDD and UKL2AR22KDD are ROHS3 compliant, meeting current regulatory requirements for electronic component manufacturing.

Q: Will the UKL2AR22KDD fit the same PCB footprint?

A: Yes. Both parts maintain identical lead spacing (0.079" / 2.00mm) and physical diameter (0.197" / 5.00mm). The UKL2AR22KDD has a slightly shorter maximum seated height (0.472" versus 0.492"), which ensures compatibility with existing board layouts.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -40°C to 85°C with a rated lifetime of 2000 hours at 85°C, making them suitable for general-purpose applications across standard industrial and commercial temperature ranges.
