Key Parameters

Substitute Part Grouping Explanation

Substitution of the ESMG201ELL331MP30S is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 200 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime: 2000 Hrs @ 85°C (exact match required)
• Operating Temperature: -40°C ~ 85°C (exact match required)
• Polarization: Polar (exact match required)

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole (exact match required)
• Package Type: Radial, Can (exact match required)
• Lead Spacing: Tolerance within PCB design specifications
• Case Diameter and Height: Physical fit within enclosure constraints

Compliance Criteria:

• RoHS3 Compliance (required for regulatory alignment)
• REACH Status: REACH Unaffected (required for supply chain compliance)

Substitute parts must satisfy all electrical parameters identically. Mechanical parameters (lead spacing, case diameter, height) may vary within the constraints of the target application's PCB layout and physical envelope.

Engineering Selection Recommendations

ESMQ201ELL331MM40S (Chemi-Con SMQ Series)

This substitute maintains full electrical equivalence with the obsolete ESMG201ELL331MP30S. Both components are manufactured by Chemi-Con and share identical capacitance, voltage rating, tolerance, and thermal specifications. The ESMQ201ELL331MM40S is currently in active production status, ensuring supply chain availability. Mechanical differences include reduced lead spacing (7.50 mm vs. 10.00 mm), smaller case diameter (18.00 mm vs. 22.00 mm), and increased height (41.50 mm vs. 31.50 mm). PCB layout modification is required to accommodate the different lead spacing and physical dimensions. This part is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

LDM2D331MERYGA (Nichicon LDM Series)

This substitute provides full electrical equivalence across all critical parameters: 330 µF capacitance, 200 V voltage rating, ±20% tolerance, and 2000-hour lifetime at 85°C. The Nichicon LDM series is in active production, providing long-term supply security. Mechanical dimensions differ from the main part: lead spacing is 7.50 mm (vs. 10.00 mm), case diameter is 20.00 mm (vs. 22.00 mm), and height is 1.260 inches (32.00 mm vs. 31.50 mm). The LDM2D331MERYGA offers higher ripple current capability at 50 kHz (2.235 A), which may provide performance advantages in high-frequency applications. This part is ROHS3 compliant and REACH unaffected.

Both substitute parts satisfy electrical equivalence requirements. Selection between them depends on PCB layout constraints, available board space, and ripple current performance requirements for the specific application.

Frequently Asked Questions (FAQ)

Q: Can the ESMQ201ELL331MM40S directly replace the ESMG201ELL331MP30S without PCB modification?

A: No. While electrical parameters are identical, the lead spacing differs (7.50 mm vs. 10.00 mm). PCB layout modification is required to accommodate the different lead hole spacing. Case diameter and height also differ, requiring verification of physical clearance within the enclosure.

Q: What is the primary reason for finding substitutes for the ESMG201ELL331MP30S?

A: The ESMG201ELL331MP30S is listed as obsolete. Substitute parts from active product lines (ESMQ201ELL331MM40S and LDM2D331MERYGA) ensure continued availability for production, maintenance, and field repairs.

Q: Are both substitute parts electrically equivalent to the original part?

A: Yes. Both the ESMQ201ELL331MM40S and LDM2D331MERYGA match the ESMG201ELL331MP30S across all electrical specifications: 330 µF capacitance, 200 V voltage rating, ±20% tolerance, -40°C to 85°C operating range, and 2000-hour lifetime at 85°C.

Q: Do the substitute parts meet current compliance standards?

A: Yes. Both substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: Which substitute part has better ripple current performance?

A: The LDM2D331MERYGA (Nichicon) provides higher ripple current capability at 50 kHz (2.235 A) compared to the ESMQ201ELL331MM40S (1.425 A @ 100 kHz). Selection depends on the specific frequency and ripple current requirements of the application.

Q: Can I use either substitute part interchangeably?

A: Electrical interchangeability is confirmed. However, mechanical differences in lead spacing, case diameter, and height require individual PCB layout assessment. Each substitute may require different board modifications depending on the target application's physical and electrical constraints.

Q: What inventory status should I consider when selecting a substitute?

A: The ESMQ201ELL331MM40S has 812 units in stock, while the LDM2D331MERYGA has significantly higher inventory (273,882 units). For long-term supply security, the Nichicon LDM series offers greater availability.
