Parameter Comparison

Engineering Selection Recommendations

Both substitute parts, UTS1C331MPD1TA and UTS1C331MPD1TD, are direct functional replacements for the obsolete URS1A331MPD1TA. The substitutes maintain identical electrical and mechanical specifications while offering:

• Higher voltage rating (16 V vs. 10 V), providing additional design margin
• Extended lifetime rating (5000 Hrs @ 105°C vs. 2000 Hrs @ 85°C)
• Expanded operating temperature range (-40°C ~ 105°C vs. -40°C ~ 85°C)
• Active product status ensuring ongoing availability and supply chain support
• Maintained RoHS3 compliance

The selection between UTS1C331MPD1TA and UTS1C331MPD1TD depends on lead spacing requirements and specific PCB layout constraints. Both parts are electrically and mechanically equivalent for the URS1A331MPD1TA application.

Frequently Asked Questions (FAQ)

Q: Can UTS1C331MPD1TA or UTS1C331MPD1TD be used as direct replacements for URS1A331MPD1TA?

A: Yes. Both substitute parts maintain the same capacitance (330 µF), tolerance (±20%), polarization (polar), package type (radial, can), and physical dimensions (0.315" Dia × 0.413" height). The higher voltage rating and extended lifetime are backward compatible with applications designed for the original part.

Q: What is the difference between UTS1C331MPD1TA and UTS1C331MPD1TD?

A: Both parts are electrically identical with the same capacitance, voltage rating, and performance specifications. The difference lies in lead spacing: UTS1C331MPD1TA has 0.138" (4.60mm) lead spacing, while UTS1C331MPD1TD also has 0.138" (4.60mm) lead spacing. Verify PCB footprint compatibility before selection.

Q: Why is the voltage rating higher on the substitute parts?

A: The substitute parts are rated at 16 V compared to the original 10 V rating. This higher voltage rating provides additional design margin and does not affect compatibility in 10 V applications. The capacitor will function correctly in circuits designed for 10 V operation.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both UTS1C331MPD1TA and UTS1C331MPD1TD are ROHS3 compliant, matching the compliance status of the original URS1A331MPD1TA.

Q: What is the lead spacing for each substitute part?

A: Both substitute parts have a lead spacing of 0.138" (4.60mm). Confirm PCB hole spacing matches this specification before ordering.
