UVR2C221MHA Equivalent & Substitute Parts

Part Overview

The UVR2C221MHA is a 220 µF, 160 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, making direct replacement necessary for new procurement and ongoing system support. The UVR series represents legacy technology with a 2000-hour lifetime rating at 85°C. Equivalent and substitute parts are available from multiple manufacturers with improved specifications, including higher voltage ratings, extended operational lifetimes, and enhanced compliance certifications.

Substitute Part Grouping Explanation

Substitution for the UVR2C221MHA is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

Capacitance value: 220 µF (exact match required)
Tolerance: ±20% (exact match required)
Package type: Radial, Can (exact match required)
Lead spacing: 0.295" (7.50 mm) (exact match required)
Case diameter: 0.630" (16.00 mm) (exact match required)
Mounting type: Through Hole (exact match required)
Polarization: Polar (exact match required)

Voltage Rating Substitution Logic: Parts with equal or higher voltage ratings are acceptable substitutes. The UVR2C221MHA operates at 160 V; therefore, substitute parts rated at 160 V, 200 V, or 250 V are electrically compatible.

Lifetime and Temperature Considerations: Substitute parts may have different lifetime ratings and maximum operating temperatures. These variations do not preclude substitution but should be evaluated based on application requirements.

Compliance and Status: Product status (Obsolete, Not For New Designs, Active) and RoHS/REACH compliance are provided for procurement and regulatory planning but do not determine electrical substitutability.

Engineering Selection Recommendations

Direct Equivalent (Same Voltage): UVR2C221MHD is the direct equivalent from Nichicon, maintaining 160 V rating and identical mechanical dimensions. This part carries ROHS3 compliance and is classified as "Not For New Designs," indicating limited future availability.

Voltage-Upgraded Substitutes (200 V Rating): UVK2D221MHD, 200PX220MEFC16X35.5, EKMQ201ELL221MLP1S, ESMQ201ELL221MLP1S, MAL215252221E3, and MAL215262221E3 provide 200 V rating with identical mechanical compatibility. These parts are suitable for applications where the circuit voltage does not exceed 160 V. All carry ROHS3 compliance and active product status except UVK2D221MHD, which is "Not For New Designs."

Voltage-Upgraded Substitutes (250 V Rating): UCY2E221MHD9, 250BXW220MEFR16X35, and EKXJ251ELL221MLP1S provide 250 V rating with extended lifetime ratings (12000 Hrs @ 105°C). These parts offer superior performance margins and are recommended for new designs. All carry ROHS3 compliance and active product status.

Compliance Considerations: All substitute parts listed are ROHS3 compliant. The original UVR2C221MHA is RoHS non-compliant. Substitution with any listed part satisfies modern regulatory requirements.

Product Status Priority: For new designs, prioritize parts with "Active" status: UCY2E221MHD9, 250BXW220MEFR16X35, EKXJ251ELL221MLP1S, EKMQ201ELL221MLP1S, ESMQ201ELL221MLP1S, 200PX220MEFC16X35.5, MAL215252221E3, and MAL215262221E3.

Frequently Asked Questions (FAQ)

Q: Can I use a 200 V or 250 V rated capacitor in place of the 160 V UVR2C221MHA? A: Yes. Higher voltage-rated capacitors are electrically compatible substitutes. The circuit voltage must not exceed 160 V; the capacitor's voltage rating only needs to equal or exceed the applied voltage.

Q: What is the difference between UVR2C221MHA and UVR2C221MHD? A: Both are 160 V, 220 µF Nichicon capacitors with identical electrical and mechanical specifications. UVR2C221MHD is ROHS3 compliant, while UVR2C221MHA is not. UVR2C221MHD is classified as "Not For New Designs."

Q: Why do some substitute parts have different heights? A: Height variations (1.457" vs. 1.476") are within acceptable mechanical tolerance for through-hole radial capacitors. Both dimensions accommodate standard PCB layouts with 0.295" lead spacing.

Q: Are automotive-rated parts (AEC-Q200) required for this application? A: AEC-Q200 certification is provided on EKXJ251ELL221MLP1S and MAL215252221E3/MAL215262221E3. This certification is required only if the application is automotive. For general-purpose applications, non-automotive-rated parts are acceptable.

Q: What is the advantage of 250 V rated parts over 160 V or 200 V? A: 250 V rated parts (UCY2E221MHD9, 250BXW220MEFR16X35, EKXJ251ELL221MLP1S) provide higher voltage margin and extended lifetime ratings (12000 Hrs @ 105°C vs. 2000 Hrs @ 85°C), improving system reliability and longevity.

Q: Can I mix different manufacturers' capacitors in the same circuit? A: Yes. All listed substitute parts meet identical electrical and mechanical specifications. Mixing manufacturers is acceptable from an engineering standpoint, though procurement and inventory management may favor single-source selection.

Q: What does "Not For New Designs" mean? A: This status indicates the manufacturer is discontinuing the product line. Parts with this designation should not be selected for new product development. Active-status alternatives are recommended.
