Nichicon UML1C470MDD Equivalent & Substitute Parts

Part Overview

The Nichicon UML1C470MDD is a 47 µF, 16 V aluminum electrolytic capacitor in radial, can package configuration. This component is rated for 1000 hours at 85°C operating temperature and is designed for general-purpose applications requiring polar capacitive filtering. The part is currently in active product status with ROHS3 compliance and REACH unaffected classification.

Equivalent and substitute parts are necessary when the original UML1C470MDD becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design specifications allow for enhanced performance characteristics such as extended lifetime ratings or improved ripple current handling.

Engineering Selection Recommendations

Direct Replacement (Identical Footprint & Lifetime):

ECE-A1CKS470I is the optimal direct replacement for UML1C470MDD. Both parts share identical lead spacing (0.098" / 2.50mm), identical physical dimensions (0.248" diameter, 0.236" height), and equivalent 1000-hour lifetime rating at 85°C. Both are ROHS3 compliant and REACH unaffected. The ECE-A1CKS470I is currently in active product status and available in Cut Tape packaging.

Footprint-Compatible Alternatives (1000 Hrs Lifetime):

ECE-A1CKA470, ECE-A1CKA470B, and ECE-A1CKA470I maintain the 1000-hour lifetime specification but feature different physical dimensions and lead spacing configurations. These parts are suitable when PCB layout accommodates the dimensional variations. All three are Panasonic products in active status with ROHS3 compliance.

Enhanced Performance Substitutes (2000 Hrs Lifetime):

ECA-1CM470, ECA-1CM470B, ECA-1CM470I, UVR1C470MDD1TA, UVR1C470MDD1TD, and ESMG160ELL470ME11D provide doubled thermal endurance (2000 hours at 85°C). These parts are suitable for applications requiring extended operational life or operating in elevated thermal environments. All maintain 47 µF capacitance, 16 V rating, ±20% tolerance, and ROHS3 compliance. Note that UVR1C470MDD1TA and UVR1C470MDD1TD are classified as obsolete products.

Active Product Status Priority:

For new designs and ongoing procurement, prioritize parts with active product status: ECE-A1CKS470I, ECE-A1CKA470, ECE-A1CKA470B, ECE-A1CKA470I, ECA-1CM470, ECA-1CM470B, ECA-1CM470I, and ESMG160ELL470ME11D. Avoid UVR1C470MDD1TA and UVR1C470MDD1TD due to obsolete classification.

Frequently Asked Questions (FAQ)

Q: Can ECE-A1CKS470I replace UML1C470MDD without PCB modification?

A: Yes. ECE-A1CKS470I shares identical lead spacing (2.50mm), diameter (6.30mm), and height (6.00mm) with UML1C470MDD. Both are 47 µF, 16 V, ±20% tolerance, polar radial capacitors with 1000-hour lifetime at 85°C. No PCB layout changes are required.

Q: What is the difference between 1000-hour and 2000-hour lifetime ratings?

A: Lifetime rating indicates the thermal endurance specification at 85°C. A 2000-hour rating provides twice the operational life expectancy compared to 1000-hour rated parts under identical thermal stress conditions. Selection depends on application reliability requirements and expected operating temperature profiles.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the environmental compliance profile of the original UML1C470MDD.

Q: How does lead spacing affect substitution?

A: Lead spacing determines PCB hole pattern compatibility. UML1C470MDD uses 2.50mm spacing. Substitute parts with identical 2.50mm spacing (ECE-A1CKS470I, ECE-A1CKA470I, ECA-1CM470I, UVR1C470MDD1TD) are direct PCB replacements. Parts with 2.00mm or 5.00mm spacing require PCB layout verification or modification.

Q: Can I use a 2000-hour rated part in place of a 1000-hour rated part?

A: Yes. A 2000-hour rated part exceeds the thermal endurance specification of a 1000-hour rated part. Electrical parameters (capacitance, voltage, tolerance) remain identical. Verify physical dimensions and lead spacing compatibility with PCB layout before substitution.

Q: What packaging formats are available?

A: Substitute parts are available in Bulk, Cut Tape (CT), and Tape & Box (TB) packaging. Packaging selection depends on manufacturing process requirements and procurement volume. Electrical and mechanical specifications remain constant across packaging formats.

Q: Why are UVR1C470MDD1TA and UVR1C470MDD1TD classified as obsolete?

A: Obsolete classification indicates these parts are no longer in active production. While inventory may remain available, new designs should prioritize active status parts to ensure long-term supply chain continuity and manufacturing support.
