Engineering Selection Recommendations

Direct Substitutes (Identical Electrical Specifications):

865230142002 (Würth Elektronik WCAP-AS5H series) is a direct substitute with identical capacitance, voltage, and tolerance. This part offers extended lifetime (5000 Hrs @ 105°C versus 2000 Hrs @ 85°C) and wider operating temperature range (-40°C ~ 105°C). Product status is Active, ensuring continued availability and manufacturing support.

UWX0J330MCL1GB (Nichicon UWX series) matches the electrical specifications exactly but carries Obsolete product status. This part is suitable only for legacy system maintenance or when existing inventory must be consumed. REACH status is Unaffected.

Upgrade Substitutes (Enhanced Specifications):

865060242002 (Würth Elektronik WCAP-ASLL series) provides higher voltage rating (10 V) with identical capacitance and tolerance. Operating temperature extends to -55°C ~ 105°C. Product status is Active.

865080442006 (Würth Elektronik WCAP-ASLI series) provides the highest voltage rating (25 V) among substitutes with identical capacitance and tolerance. Operating temperature extends to -55°C ~ 105°C. Product status is Active.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage rated capacitor as a substitute?

A: Yes. A capacitor with voltage rating equal to or higher than 6.3 V is electrically compatible. Higher voltage ratings provide additional safety margin in the circuit. All listed upgrade substitutes with 10 V, 16 V, or 25 V ratings are acceptable replacements.

Q: What is the difference between Direct and Upgrade substitutes?

A: Direct substitutes maintain identical electrical and thermal specifications as the original 865250142003. Upgrade substitutes offer enhanced performance through higher voltage ratings, extended temperature ranges, or longer lifetime ratings. Selection depends on circuit requirements and design margins.

Q: Are Obsolete parts acceptable for new designs?

A: Obsolete parts such as UWJ0J330MCL1GB and UWX0J330MCL1GB are suitable only for maintenance of existing systems or consumption of existing inventory. New designs should use Active status parts to ensure long-term supply chain stability.

Q: What does "Not For New Designs" status mean?

A: Parts with Not For New Designs status, including EEE-1AA330AR and EEE-1AA330SR, are available for existing applications but should not be selected for new product development. These parts may have limited future availability or manufacturing support.

Q: Does packaging type affect substitution?

A: Yes. All substitutes must use Surface Mount Radial Can package with identical physical dimensions (0.197" Dia, 0.217" Height maximum) and land size (0.209" L x 0.209" W). UWJ0J330MCL1GB uses Cut Tape & Digi-Reel packaging instead of standard Tape & Reel, which may affect procurement and handling procedures.

Q: What is the significance of Bi-Polar versus Polar polarization?

A: The original 865250142003 is Bi-Polar, allowing connection in either polarity. All listed substitutes are Polar, requiring correct polarity orientation in the circuit. Verify circuit design accommodates polar connection before substitution.

Q: Can I use parts with extended temperature ranges in standard applications?

A: Yes. Parts with wider operating temperature ranges such as 865060242002 (-55°C ~ 105°C) are fully compatible with standard -40°C ~ 85°C applications. Extended range provides additional design margin without circuit modification.

Q: What is the impact of different lifetime ratings?

A: Lifetime rating indicates expected operational duration at specified temperature. 865230142002 with 5000 Hrs @ 105°C provides longer service life than the original 2000 Hrs @ 85°C. Higher lifetime ratings are beneficial for reliability-critical applications.
