Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters:

Capacitance: 1000 µF (exact match required)
Voltage Rating: 35 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)
Lead Spacing: 0.197" (5.00 mm) (exact match required)
Operating Temperature Range: -55°C to 105°C (exact match required)

All four substitute parts meet these core electrical and mechanical requirements. Variations in lifetime rating, impedance, ripple current specifications, and manufacturer certifications do not disqualify substitution but indicate performance differentiation.

Engineering Selection Recommendations

All four substitute parts satisfy the core electrical and mechanical compatibility requirements for direct substitution with 860080578021.

860160578032 (Würth Elektronik WCAP-ATLL) provides extended lifetime of 7000 hours at 105°C while maintaining identical lead spacing and mounting footprint. Product status is Active.

EEU-FC1V102B (Panasonic FC series) carries AEC-Q200 automotive qualification and is rated for automotive applications. Product status is Active. Physical dimensions differ slightly (0.492" diameter versus 0.512", height 1.063" versus 1.043"), requiring PCB layout verification.

MAL215030102E3 (Vishay 150 RMI series) offers the highest lifetime rating of 8000 hours at 105°C with AEC-Q200 automotive qualification. Product status is Active. Physical dimensions differ from the primary part (0.492" diameter, 1.063" height).

UPW1V102MHD1TO (Nichicon UPW series) provides 7000-hour lifetime at 105°C. Product status is designated as Not For New Designs, indicating this part is in end-of-life phase and should not be selected for new design implementations.

Frequently Asked Questions (FAQ)

Q: Can these substitute parts be used interchangeably with 860080578021?

A: Yes, all four substitute parts meet the core electrical specifications (1000 µF, 35 V, ±20% tolerance) and mechanical requirements (Through Hole, Radial Can package, 0.197" lead spacing, -55°C to 105°C operating range). However, physical dimensions vary for three of the substitutes, requiring PCB layout verification before implementation.

Q: What is the difference between the Würth parts 860080578021 and 860160578032?

A: Both are Würth Elektronik radial aluminum electrolytic capacitors with identical electrical ratings and lead spacing. The primary difference is lifetime: 860160578032 (WCAP-ATLL series) is rated for 7000 hours at 105°C compared to 5000 hours for 860080578021 (WCAP-ATLI series). Both are Active products.

Q: Why do some substitute parts have different physical dimensions?

A: Panasonic EEU-FC1V102B, Vishay MAL215030102E3, and Nichicon UPW1V102MHD1TO have slightly smaller diameters (0.492" versus 0.512") and greater heights (1.063" versus 1.043"). These dimensional variations are within the same package category (Radial, Can) but require verification that PCB footprints and clearances accommodate the differences.

Q: Should UPW1V102MHD1TO be selected for new designs?

A: No. UPW1V102MHD1TO carries a product status of Not For New Designs, indicating end-of-life classification. For new design implementations, select from the three Active-status alternatives: 860160578032, EEU-FC1V102B, or MAL215030102E3.

Q: Which substitute offers the longest operational lifetime?

A: MAL215030102E3 (Vishay 150 RMI series) is rated for 8000 hours at 105°C, the highest among all options. This part also carries AEC-Q200 automotive qualification.

Q: Are automotive-qualified parts required for this application?

A: Automotive qualification (AEC-Q200) is provided by EEU-FC1V102B and MAL215030102E3. Selection depends on application requirements. The primary part 860080578021 and alternatives 860160578032 and UPW1V102MHD1TO do not carry automotive ratings but are suitable for general purpose applications.
