Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance): UPW1A151MED is the direct equivalent substitute for SXR151M010ST. Both components share identical capacitance (150 µF), voltage rating (10 V), tolerance (±20%), and mechanical dimensions (lead spacing 2.50 mm, height 11.00 mm). Both are ROHS3 compliant and rated for 2000 hours at 105°C. This substitute maintains functional equivalence for applications requiring no design modification.

For Voltage Margin Enhancement: UPW1C151MED (16 V) and UHV1E151MED (25 V) provide increased voltage headroom while maintaining mechanical compatibility. UHV1E151MED additionally offers extended lifetime (5000 hours at 105°C), suitable for applications requiring enhanced reliability margins. Both are ROHS3 compliant and support the full operating temperature range.

For Extended Operational Lifetime and Active Product Status: 25ZLJ150M6.3X11 (Rubycon, 25 V) is an active product with 7000-hour lifetime at 105°C, providing the longest operational duration among all substitutes. This part accommodates slightly increased height (12.50 mm vs. 11.00 mm) and offers superior ripple current handling (350 mA @ 120 Hz, 700 mA @ 100 kHz). ROHS3 compliance and REACH unaffected status confirm regulatory alignment.

Compliance Considerations: All substitute parts maintain ROHS3 compliance, ensuring regulatory compatibility with existing design documentation and procurement standards. The 25ZLJ150M6.3X11 additionally carries REACH unaffected status, providing extended supply chain assurance.

Frequently Asked Questions (FAQ)

Q: Can UPW1A151MED replace SXR151M010ST without circuit modification?

A: Yes. UPW1A151MED is a direct equivalent with identical capacitance (150 µF), voltage rating (10 V), tolerance (±20%), lead spacing (2.50 mm), and package configuration (radial, can, through-hole). Both components are ROHS3 compliant and rated for 2000 hours at 105°C. No circuit modification is required.

Q: What is the advantage of using UHV1E151MED or UPW1C151MED over UPW1A151MED?

A: UHV1E151MED (25 V) and UPW1C151MED (16 V) provide higher voltage ratings than the original 10 V specification. Higher voltage ratings increase design margin and reduce stress on the capacitor in applications subject to voltage transients or supply variations. UHV1E151MED additionally extends lifetime to 5000 hours at 105°C, improving long-term reliability.

Q: Is 25ZLJ150M6.3X11 mechanically compatible with the original SXR151M010ST?

A: 25ZLJ150M6.3X11 maintains compatible lead spacing (2.50 mm) and diameter (6.30 mm). However, height increases from 11.00 mm to 12.50 mm. Verify available board space before substitution. All other mechanical parameters (radial, can, through-hole mounting) remain compatible.

Q: Why is 25ZLJ150M6.3X11 listed as "Active" product status while others are "Obsolete"?

A: 25ZLJ150M6.3X11 is currently manufactured by Rubycon and available through active distribution channels. UPW1A151MED, UHV1E151MED, and UPW1C151MED are obsolete Nichicon products with limited remaining inventory. For new designs or long-term supply assurance, 25ZLJ150M6.3X11 is preferred.

Q: What is the difference in ripple current handling between these substitutes?

A: Ripple current capacity varies: SXR151M010ST (144 mA @ 120 Hz), UPW1A151MED and UPW1C151MED (188.5 mA @ 120 Hz), UHV1E151MED (220 mA @ 120 Hz), and 25ZLJ150M6.3X11 (350 mA @ 120 Hz). Higher ripple current capacity indicates better performance in high-frequency switching applications. Select based on circuit ripple current requirements.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitutes (UPW1A151MED, UHV1E151MED, UPW1C151MED, and 25ZLJ150M6.3X11) are ROHS3 compliant, ensuring regulatory alignment with environmental and hazardous substance restrictions.

Q: Can I use a 25 V rated capacitor in a 10 V circuit?

A: Yes. Voltage rating indicates maximum safe operating voltage. Using a higher-rated capacitor (25 V) in a lower-voltage circuit (10 V) is electrically safe and provides additional design margin. However, verify that physical dimensions accommodate available board space.
