Key Parameters

Substitute Part Grouping Explanation

Substitution of the UPS1A331MPD1TA is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 330 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package Type: Radial, Can (exact match required)
• Lead Spacing: 0.138" (4.60 mm) (exact match required)
• Physical Diameter: 0.315" (8.00 mm) (exact match required)
• Height: 0.512" (13.00 mm) (exact match required)
• Mounting Type: Through Hole (exact match required)

Allowable Variation Parameters:

• Voltage Rating: May be equal or higher than 10 V
• Lifetime @ Temperature: May be equal or higher than 2000 Hrs @ 105°C
• ESR and Ripple Current: May vary within acceptable operating ranges
• Product Status: Active status preferred over "Not For New Designs"

Substitute parts are grouped into two categories: Upgrade parts offering enhanced specifications (higher voltage or longer lifetime), and Parametric Equivalent parts maintaining identical electrical specifications with different packaging variants.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: Select UPA1C331MPD1TA or UPA1E331MPD1TA. Both parts carry Active product status and offer extended lifetime ratings (3000 Hrs @ 105°C versus 2000 Hrs). The UPA series provides superior reliability for long-term applications. UPA1C331MPD1TA (16 V) is suitable for circuits with 10 V nominal operation, providing voltage margin. UPA1E331MPD1TA (25 V) offers additional voltage headroom for applications with transient overvoltage conditions.

For Existing Designs (Maintenance/Repair): UPS1A331MPD1TD provides parametric equivalence to the original UPS1A331MPD1TA with identical electrical specifications. This part maintains the same 10 V rating and 2000-hour lifetime, ensuring drop-in compatibility. Inventory availability (1682 Pcs) supports ongoing production requirements.

For Cost-Optimized Alternatives: UKA1A331MPD1TD maintains the original 10 V specification and 2000-hour lifetime while offering higher inventory availability (2240 Pcs). This part is suitable for applications where voltage and lifetime specifications are non-negotiable.

Compliance Considerations: All substitute parts maintain ROHS3 compliance. UPA1C331MPD1TA and UPA1E331MPD1TA carry REACH Affected status, while UPS1A331MPD1TA, UKA1A331MPD1TD, and UPS1A331MPD1TD maintain REACH Unaffected status. Verify compliance requirements for your specific application and regulatory jurisdiction.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage-rated capacitor as a substitute? A: Yes. A 16 V or 25 V rated capacitor can replace a 10 V capacitor in the same physical package, provided all other parameters (capacitance, tolerance, lead spacing, diameter, height) remain identical. Higher voltage ratings provide additional safety margin against transient overvoltage.

Q: What is the difference between UPS1A331MPD1TA and UPS1A331MPD1TD? A: Both parts are parametrically identical with matching capacitance (330 µF), voltage (10 V), tolerance (±20%), and lifetime (2000 Hrs @ 105°C). The difference lies in packaging variant designation (TA versus TD). Both are suitable for through-hole mounting with identical lead spacing and physical dimensions.

Q: Why should I choose UPA series over UPS series? A: UPA series parts carry Active product status and offer extended lifetime (3000 Hrs @ 105°C) compared to UPS series (2000 Hrs @ 105°C). For new designs, Active status ensures long-term availability and manufacturing support. Extended lifetime improves reliability in demanding applications.

Q: Are all substitute parts pin-compatible? A: Yes. All listed substitute parts maintain identical lead spacing (0.138" / 4.60 mm), physical diameter (0.315" / 8.00 mm), and height (0.512" / 13.00 mm). All are radial, through-hole mounted components with polar configuration. Direct PCB mounting compatibility is assured.

Q: What does "Not For New Designs" mean? A: This designation indicates the part has reached end-of-life status and is no longer recommended for new product development. Existing inventory may remain available for maintenance and repair of legacy systems. For new applications, select parts with Active status such as UPA1C331MPD1TA or UPA1E331MPD1TA.

Q: How do I determine which substitute is appropriate for my application? A: Verify your circuit's voltage requirement. If your design operates at 10 V nominal with no transient overvoltage, UPS1A331MPD1TD provides direct equivalence. If voltage margin is desired, select UPA1C331MPD1TA (16 V). For applications requiring maximum reliability and extended service life, UPA1E331MPD1TA (25 V) with 3000-hour lifetime is optimal.
