ESMQ100ELL331MF11D Equivalent & Substitute Parts

Part Overview

The ESMQ100ELL331MF11D is a 330 µF, 10 V aluminum electrolytic capacitor in radial, can package manufactured by Chemi-Con. This component is rated for 2000 hours at 85°C and is designed for general-purpose applications requiring through-hole mounting. The part is currently active in production status with ROHS3 compliance and REACH unaffected certification.

Substitute parts are necessary when the original ESMQ100ELL331MF11D becomes unavailable due to supply constraints, end-of-life status, or when design requirements necessitate enhanced performance characteristics such as extended lifetime ratings or higher voltage ratings.

Substitute Part Grouping Explanation

Substitute parts for the ESMQ100ELL331MF11D are classified into three categories based on electrical and mechanical compatibility:

Direct Equivalents (Same Voltage Rating - 10V): Parts that maintain identical voltage rating, capacitance, tolerance, and physical dimensions. These parts are interchangeable in applications where the original 10 V rating is specified. Direct equivalents include EKZN100ELL331MF11D (Chemi-Con), 10ZLJ330M6.3X11 (Rubycon), and UVR1A331MED (Nichicon).

Parametric Equivalents (Same Voltage Rating - 10V, Different Manufacturer): Parts that match the 10 V voltage rating and 330 µF capacitance with identical physical footprint and lead spacing. ECA-1AM331 (Panasonic Electronic Components) falls into this category, offering the same electrical specifications within the same package envelope.

Upgrade Options (Higher Voltage Rating - 16V): Parts rated at 16 V with 330 µF capacitance maintain backward compatibility in circuits designed for 10 V operation, as higher voltage-rated capacitors can be used in lower voltage applications. These include 16PK330MEFC6.3X11, 16YXJ330M6.3X11, 16ZLQ330MEFC6.3X11 (all Rubycon), and UVK1C331MED (Nichicon).

Substitution Criteria:

Capacitance: 330 µF (fixed requirement)
Tolerance: ±20% (fixed requirement)
Lead Spacing: 0.098" (2.50mm) (fixed requirement)
Size / Dimension: 0.248" Dia (6.30mm) (fixed requirement)
Height - Seated (Max): 0.492" (12.50mm) or 0.480" (12.20mm) (acceptable variance)
Mounting Type: Through Hole (fixed requirement)
Package / Case: Radial, Can (fixed requirement)
Voltage Rating: 10 V minimum (higher ratings acceptable)

Engineering Selection Recommendations

For Direct Replacement (Same Specifications):

EKZN100ELL331MF11D (Chemi-Con, KZN series) is the primary direct substitute. It maintains identical voltage, capacitance, tolerance, and physical dimensions while offering extended lifetime (7000 hours at 105°C versus 2000 hours at 85°C). This part is active in production status with ROHS3 compliance.

10ZLJ330M6.3X11 (Rubycon, ZLJ series) provides equivalent electrical and mechanical specifications with extended lifetime rating. This part is active in production status with ROHS3 compliance and offers higher ripple current capability at high frequency (700 mA @ 100 kHz).

ECA-1AM331 (Panasonic Electronic Components, M-A series) is functionally equivalent with identical voltage and capacitance ratings. Height dimension is 0.480" (12.20mm) versus 0.492" (12.50mm), representing a 0.012" reduction. This part is active in production status with ROHS3 compliance.

For Obsolete Part Replacement:

UVR1A331MED (Nichicon, UVR series) is marked as obsolete. Direct substitutes from active manufacturers are EKZN100ELL331MF11D, 10ZLJ330M6.3X11, or ECA-1AM331.

UVK1C331MED (Nichicon, UVK series) is marked as obsolete. This 16 V rated part can be replaced with active 16 V alternatives: 16YXJ330M6.3X11 (Rubycon, 7000 hours @ 105°C) or 16PK330MEFC6.3X11 (Rubycon, 2000 hours @ 85°C).

For Voltage Upgrade Applications:

16V-rated parts (16PK330MEFC6.3X11, 16YXJ330M6.3X11, 16ZLQ330MEFC6.3X11, UVK1C331MED) are suitable for circuits originally designed for 10 V operation. All maintain identical physical footprint and lead spacing. Selection among 16 V options depends on required lifetime rating and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can EKZN100ELL331MF11D directly replace ESMQ100ELL331MF11D?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (10 V), tolerance (±20%), lead spacing (0.098" / 2.50mm), diameter (0.248" / 6.30mm), and height (0.492" / 12.50mm). EKZN100ELL331MF11D offers extended lifetime (7000 hours @ 105°C) and expanded operating temperature range (-40°C ~ 105°C).

Q: What is the difference between 10V and 16V rated parts in this series?

A: The voltage rating indicates the maximum continuous DC voltage the capacitor can withstand. 16V-rated parts can be used in 10V circuits without electrical degradation. Physical dimensions remain identical. Selection of 16V parts provides design margin for voltage transients or future circuit modifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed in this reference maintain ROHS3 compliance and REACH unaffected status, matching the original ESMQ100ELL331MF11D certification.

Q: What does "Lifetime @ Temperature" mean?

A: This specification indicates the expected operational life of the capacitor under continuous operation at the stated temperature. ESMQ100ELL331MF11D is rated for 2000 hours at 85°C. Extended lifetime parts such as EKZN100ELL331MF11D (7000 hours @ 105°C) provide longer service life in high-temperature environments.

Q: Can I use ECA-1AM331 if my PCB layout requires exactly 0.492" height?

A: ECA-1AM331 has a maximum seated height of 0.480" (12.20mm), which is 0.012" shorter than the original specification. If your PCB layout has a height constraint of 0.492", this part will fit with clearance. If your design requires exactly 0.492" for mechanical alignment, use EKZN100ELL331MF11D, 10ZLJ330M6.3X11, or UVR1A331MED instead.

Q: Why are UVR1A331MED and UVK1C331MED marked as obsolete?

A: Obsolete status indicates these parts are no longer in active production. Active alternatives with equivalent or superior specifications are available from current manufacturers. Use EKZN100ELL331MF11D, 10ZLJ330M6.3X11, or ECA-1AM331 for 10V applications; use 16YXJ330M6.3X11 or 16PK330MEFC6.3X11 for 16V applications.

Q: What is the significance of ripple current ratings?

A: Ripple current indicates the AC current the capacitor can handle at specified frequencies without exceeding temperature limits. Higher ripple current capability allows the capacitor to operate in circuits with greater AC stress. EKZN100ELL331MF11D and 10ZLJ330M6.3X11 offer higher ripple current at 100 kHz (700 mA) compared to the original ESMQ100ELL331MF11D (435 mA @ 100 kHz).

Q: Are all parts in this reference suitable for general-purpose applications?

A: Yes. All listed parts are rated for general-purpose applications. Specific application suitability depends on circuit voltage, temperature environment, ripple current requirements, and lifetime expectations. Consult circuit design specifications to select the appropriate substitute.
