Substitute Part Grouping Explanation

Substitution of the Würth Elektronik 860020275021 is determined by strict equivalence in the following parameters:

• Capacitance: 2700 µF (exact match required)
• Voltage Rating: 10 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Configuration: Radial, Can (exact match required)
• Lead Spacing: 0.197" (5.00 mm) (exact match required)
• Size / Dimension: 0.394" Dia (10.00 mm) (exact match required)
• Operating Temperature Range: -40°C ~ 105°C (exact match required)

The Panasonic Electronic Components EEU-FS1A272LB meets all mandatory substitution criteria. This part is classified as an upgrade substitute due to enhanced lifetime performance (10000 Hrs @ 105°C versus 2000 Hrs @ 105°C) while maintaining identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the Würth Elektronik 860020275021 and Panasonic Electronic Components EEU-FS1A272LB are Active products with ROHS3 compliance and REACH Unaffected status. The Panasonic EEU-FS1A272LB provides extended operational lifetime (10000 Hrs @ 105°C) compared to the Würth part (2000 Hrs @ 105°C) while maintaining identical electrical ratings and mechanical form factor. Both parts are suitable for general-purpose applications and are pin-compatible for direct board-level substitution.

Frequently Asked Questions (FAQ)

Q: Can the Panasonic EEU-FS1A272LB be used as a direct replacement for the Würth Elektronik 860020275021?

A: Yes. Both parts share identical capacitance (2700 µF), voltage rating (10 V), tolerance (±20%), lead spacing (5.00 mm), case diameter (10.00 mm), and operating temperature range (-40°C ~ 105°C). The maximum seated height differs by 0.02" (0.50 mm), which is within typical PCB design tolerances for radial capacitors.

Q: What is the primary difference between these two parts?

A: The Panasonic part offers a 5× increase in rated lifetime at 105°C (10000 Hrs versus 2000 Hrs). Both parts are electrically and mechanically equivalent for board-level substitution.

Q: Are both parts RoHS compliant?

A: Yes. Both the Würth Elektronik 860020275021 and Panasonic EEU-FS1A272LB are ROHS3 Compliant and REACH Unaffected.

Q: What is the lead spacing for these capacitors?

A: Both parts have a lead spacing of 0.197" (5.00 mm), ensuring compatibility with standard PCB footprints designed for radial aluminum electrolytic capacitors in this size class.

Q: Are there any height clearance concerns when substituting?

A: The Panasonic part has a maximum seated height of 1.063" (27.00 mm) compared to 1.043" (26.50 mm) for the Würth part. This 0.02" (0.50 mm) difference is negligible for most applications but should be verified against specific PCB design constraints if space is limited.
