Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SXR331M010ST are classified into three categories based on electrical and mechanical compatibility:

Direct Equivalent (Same Voltage Rating - 10V):

• UPW1A331MPD (Nichicon): Maintains 330 µF capacitance and 10 V voltage rating with identical lead spacing (3.50 mm) and through-hole radial mounting. Operating temperature range extends to -55°C. Lifetime specification matches at 3000 hours @ 105°C.

Upgrade Substitutes (Higher Voltage Rating - 16V):

• ESW337M016AG3AA (KEMET): 330 µF, 16 V rating with improved ESR (130 mOhm @ 100kHz) and extended lifetime (4000 Hrs @ 105°C). Identical mechanical footprint and lead spacing.
• UHE1C331MPD (Nichicon): 330 µF, 16 V rating with superior lifetime (7000 Hrs @ 105°C). Maintains identical lead spacing and through-hole mounting.
• UPW1C331MPD (Nichicon): 330 µF, 16 V rating with 3000-hour lifetime. Extended operating temperature to -55°C. Identical mechanical dimensions.

Similar Substitute (Higher Voltage Rating - 16V):

• 16YXF330MEFC8X11.5 (Rubycon): 330 µF, 16 V rating with 7000-hour lifetime. Maintains lead spacing and radial can package with slightly increased height (13.00 mm vs. 12.00 mm).

Substitution logic is based on matching capacitance (330 µF), tolerance (±20%), mechanical footprint (lead spacing 3.50 mm, diameter 8.00 mm), mounting type (through-hole radial), and package style (radial can). Voltage rating upgrades from 10 V to 16 V provide design margin without affecting physical compatibility.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Voltage): UPW1A331MPD is the appropriate direct equivalent, maintaining the 10 V voltage rating while providing identical capacitance and mechanical compatibility. This part is suitable for applications where voltage margin is not a design constraint.

For Upgraded Performance: ESW337M016AG3AA (KEMET, Active status) is recommended for new designs requiring higher reliability. This part offers improved ESR characteristics (130 mOhm @ 100kHz) and extended lifetime (4000 hours @ 105°C) while maintaining the same physical footprint. Active product status ensures long-term availability.

UHE1C331MPD and UPW1C331MPD provide 16 V ratings with extended operating temperature ranges (-55°C for UPW1C331MPD). UHE1C331MPD offers superior lifetime (7000 hours @ 105°C), suitable for applications requiring extended service intervals.

For Space-Constrained Applications: UPW1A331MPD and UHE1C331MPD feature reduced height (11.50 mm) compared to the original part (12.00 mm), providing marginal space savings in compact designs.

Compliance Considerations: All substitute parts maintain ROHS3 compliance. ESW337M016AG3AA and 16YXF330MEFC8X11.5 carry REACH Unaffected status. UHE1C331MPD is REACH Affected, requiring verification for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can UPW1A331MPD be used as a direct replacement for SXR331M010ST? A: Yes. UPW1A331MPD maintains identical capacitance (330 µF), voltage rating (10 V), tolerance (±20%), lead spacing (3.50 mm), and through-hole radial mounting. Physical compatibility is confirmed across all mechanical dimensions.

Q: What is the advantage of upgrading to a 16 V rated substitute? A: A 16 V rated substitute provides design margin in applications where voltage stress may vary. The higher voltage rating does not affect physical compatibility or electrical performance in 10 V circuits. Upgrade options also offer improved ESR characteristics and extended lifetime specifications.

Q: Are there height restrictions when substituting? A: The original SXR331M010ST has a maximum seated height of 12.00 mm. UPW1A331MPD and UHE1C331MPD are slightly shorter (11.50 mm), providing marginal space savings. ESW337M016AG3AA (12.50 mm) and 16YXF330MEFC8X11.5 (13.00 mm) require verification for space-constrained PCB layouts.

Q: Which substitute is recommended for new designs? A: ESW337M016AG3AA (KEMET) carries Active product status, ensuring long-term availability and manufacturing support. This part is the preferred choice for new design implementations requiring 330 µF, 16 V aluminum electrolytic capacitors in radial can packages.

Q: Do all substitutes maintain the same lead spacing? A: Yes. All substitute parts maintain 3.50 mm lead spacing and 8.00 mm diameter, ensuring direct PCB footprint compatibility without layout modifications.

Q: What is the difference between ESR specifications across parts? A: ESR values vary by measurement frequency and manufacturer design. SXR331M010ST specifies 760 mOhm @ 120Hz. ESW337M016AG3AA provides 130 mOhm @ 100kHz, indicating lower impedance at high frequencies. Other substitutes do not publish ESR values in the provided data.

Q: Are there REACH compliance differences among substitutes? A: ESW337M016AG3AA and 16YXF330MEFC8X11.5 are REACH Unaffected. UHE1C331MPD is REACH Affected. Applications subject to REACH regulations should verify compliance requirements before selection.

Q: Can ripple current ratings be compared directly across parts? A: Ripple current specifications are frequency-dependent. Direct comparison requires matching measurement frequencies. SXR331M010ST specifies 240 mA @ 120Hz and 400 mA @ 100kHz. Substitutes provide varying ripple current ratings at different frequencies; verify application requirements before selection.
