Engineering Selection Recommendations

Direct Substitution (Same Manufacturer, Voltage Upgrade): Würth Elektronik 860040672001 is a direct upgrade substitute with identical mechanical dimensions and lead spacing (0.079" / 2.00mm). The 50 V voltage rating provides additional design margin over the original 35 V specification while maintaining all other electrical and mechanical parameters. Product status is Active, ensuring long-term availability.

Cross-Manufacturer Substitution (Lead Spacing Variation): Rubycon 50YXJ22MTA5X11 is electrically equivalent with Active product status. However, the lead spacing is 0.197" (5.00mm) compared to the original 0.079" (2.00mm). PCB layout modification is required for this substitution.

Rubycon 50YXF22MEFCT15X11 is electrically equivalent but carries Last Time Buy product status, indicating discontinued production. The lead spacing is 0.098" (2.50mm), requiring PCB layout adjustment. This part should be selected only when other options are unavailable.

Compliance Basis: All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and EAR99 ECCN classification, matching the original component's regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can I use a 50 V rated capacitor in place of a 35 V rated capacitor? A: Yes. A higher voltage rating provides additional design margin and is electrically compatible. The 50 V substitutes (860040672001, 50YXF22MEFCT15X11, 50YXJ22MTA5X11) are all qualified replacements for the 35 V original component.

Q: What is the significance of lead spacing differences? A: Lead spacing determines PCB hole positioning. The original 860240572002 uses 0.079" (2.00mm) spacing. Rubycon 50YXF22MEFCT15X11 uses 0.098" (2.50mm) and 50YXJ22MTA5X11 uses 0.197" (5.00mm). Direct PCB mounting is possible only with matching lead spacing. Non-matching lead spacing requires PCB redesign or manual lead bending.

Q: Are all substitutes available in the same packaging? A: Yes. All listed substitutes are supplied in Cut Tape (CT) packaging, matching the original component's packaging format.

Q: What does "Last Time Buy" product status mean? A: Last Time Buy indicates the manufacturer has discontinued production. Rubycon 50YXF22MEFCT15X11 is in this status. Existing inventory may be available, but future procurement is not guaranteed. Active status parts (860040672001, 50YXJ22MTA5X11) are preferred for new designs.

Q: Do all substitutes meet the same compliance standards? A: Yes. All substitute parts are ROHS3 Compliant, REACH Unaffected, and classified as EAR99, matching the original component's regulatory profile.
