Substitute Part Grouping Explanation

Substitute parts for the EEU-FS2A271L are qualified based on the following criteria:

Capacitance: 270 µF (exact match required)
Voltage Rating: 100 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime @ Temperature: 10,000 Hrs @ 105°C (exact match required)
Operating Temperature Range: -40°C ~ 105°C (exact match required)
Lead Spacing: 0.197" (5.00 mm) (exact match required)
Package Diameter: 0.492" (12.50 mm) (exact match required)
Height - Seated (Max): 1.260" (32.00 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Package / Case: Radial, Can (exact match required)

Both substitute parts meet these criteria and are manufactured by Rubycon. Variations in ripple current performance and impedance are documented but do not disqualify substitution when electrical and mechanical compatibility is maintained.

Engineering Selection Recommendations

All three parts—EEU-FS2A271L, 100ZLH270MEFC12.5X30, and 100ZLJ270M12.5X30—maintain Active product status and are ROHS3 compliant with REACH Unaffected designation. Both substitute parts carry identical ECCN (EAR99) and HTSUS (8532.22.0020) classifications, confirming regulatory equivalence.

Selection between these parts should be based on application-specific ripple current requirements and impedance characteristics. The EEU-FS2A271L provides the lowest impedance at 30 mOhms and highest ripple current at 100 kHz (2.2 A). The 100ZLJ270M12.5X30 offers the highest ripple current at 100 kHz (2.4 A) with intermediate impedance (42 mOhms). The 100ZLH270MEFC12.5X30 exhibits higher impedance (51 mOhms) and lower ripple current performance at 120 Hz (975 mA).

All parts are suitable for general-purpose applications within the specified electrical and thermal parameters.

Frequently Asked Questions (FAQ)

Q: Can 100ZLH270MEFC12.5X30 or 100ZLJ270M12.5X30 be used as direct replacements for EEU-FS2A271L?

A: Yes. Both Rubycon parts meet all critical electrical and mechanical specifications: 270 µF capacitance, 100 V voltage rating, ±20% tolerance, 10,000 hour lifetime at 105°C, identical lead spacing (5.00 mm), package diameter (12.50 mm), and height (32.00 mm). Through-hole mounting and radial can package are identical across all three parts.

Q: What are the differences between the two Rubycon substitute parts?

A: The primary differences are ripple current performance and impedance. The 100ZLJ270M12.5X30 provides higher ripple current at 100 kHz (2.4 A) and lower impedance (42 mOhms) compared to the 100ZLH270MEFC12.5X30 (1.95 A at 100 kHz, 51 mOhms impedance). At 120 Hz, the 100ZLJ270M12.5X30 delivers 1.2 A versus 975 mA for the 100ZLH270MEFC12.5X30.

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

A: No. All three parts are ROHS3 compliant, REACH Unaffected, and classified under identical ECCN (EAR99) and HTSUS (8532.22.0020) codes.

Q: Which substitute part should be selected for high-frequency ripple current applications?

A: The 100ZLJ270M12.5X30 is suitable for applications requiring higher ripple current at 100 kHz (2.4 A) and lower impedance (42 mOhms). The EEU-FS2A271L remains the reference specification with 2.2 A at 100 kHz and 30 mOhms impedance.

Q: Are PCB layout modifications required when substituting these parts?

A: No. All three parts share identical lead spacing (5.00 mm) and package dimensions (0.492" diameter, 1.260" height), ensuring direct PCB compatibility without layout changes.
