Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LDQ2D271MERYGA is determined by strict equivalence in the following core parameters:

• Capacitance value: 270 µF (exact match required)
• Voltage rating: 200 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Mounting type: Through Hole (exact match required)
• Package type: Radial, Can (exact match required)
• Lead spacing: 0.295" (7.50mm) (exact match required)
• Operating temperature range: -40°C ~ 105°C (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The substitute parts UCY2D271MHD and UCY2D271MHD6 meet all core electrical and mechanical compatibility criteria. Variations in physical dimensions (diameter and height), ripple current ratings, and lifetime specifications do not affect substitution eligibility, as these parameters remain within acceptable ranges for general purpose applications.

Parameter Comparison

Engineering Selection Recommendations

Both UCY2D271MHD and UCY2D271MHD6 are valid substitutes for LDQ2D271MERYGA based on electrical and mechanical equivalence. Selection between these options depends on application-specific requirements:

UCY2D271MHD and UCY2D271MHD6 offer extended lifetime ratings of 12000 Hrs @ 105°C compared to the LDQ2D271MERYGA at 2000 Hrs @ 105°C, providing enhanced reliability in continuous operation scenarios. Both substitute parts maintain ROHS3 compliance and Active product status, ensuring regulatory alignment and long-term availability.

Physical dimension variations exist between the main part and substitutes. The LDQ2D271MERYGA measures 0.787" diameter by 1.181" length, while UCY2D271MHD measures 0.630" diameter by 1.457" length, and UCY2D271MHD6 measures 0.709" diameter by 1.299" length. PCB layout and mechanical clearance must be verified before component selection to ensure physical fit within the target application.

Frequently Asked Questions (FAQ)

Q: Can UCY2D271MHD and UCY2D271MHD6 be used interchangeably with LDQ2D271MERYGA?

A: Yes. Both substitute parts match the core electrical specifications (270 µF, 200 V, ±20% tolerance) and mechanical requirements (through-hole mounting, radial can package, 7.50mm lead spacing). Electrical performance is equivalent for general purpose applications.

Q: What is the primary difference between the substitute parts?

A: UCY2D271MHD and UCY2D271MHD6 differ in physical dimensions. UCY2D271MHD has a smaller diameter (0.630") but greater height (1.457"), while UCY2D271MHD6 offers intermediate dimensions (0.709" diameter, 1.299" height). Both provide identical electrical performance and lifetime ratings.

Q: Are there compliance or regulatory differences between these parts?

A: All three parts are ROHS3 compliant and maintain Active product status. UCY2D271MHD and UCY2D271MHD6 are REACH Affected, while LDQ2D271MERYGA is REACH Unaffected. Verify REACH compliance requirements for your specific application and region.

Q: How do ripple current ratings affect substitution?

A: Substitute parts UCY2D271MHD and UCY2D271MHD6 provide higher ripple current capacity (1.4 A and 1.41 A @ 120 Hz respectively) compared to LDQ2D271MERYGA (1.1 A @ 120 Hz). This represents improved performance and does not restrict substitution eligibility.

Q: What should be verified before implementing a substitute part?

A: Verify PCB layout compatibility with the physical dimensions of the selected substitute. Confirm that the increased height of UCY2D271MHD (1.457") or UCY2D271MHD6 (1.299") does not conflict with mechanical clearance requirements in your application. Electrical performance is equivalent across all three parts.
