Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 107SAK035M is determined by strict alignment of the following critical parameters:

Electrical Parameters:

• Capacitance value: 100 µF (exact match required)
• Voltage rating: 35 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime specification: 2000 Hrs @ 85°C (exact match required)
• Operating temperature range: -40°C ~ 85°C (exact match required)

Mechanical Parameters:

• Package type: Radial, Can (exact match required)
• Mounting type: Through Hole (exact match required)
• Lead spacing: 0.138" (3.50mm) (exact match required)
• Can diameter: 0.315" (8.00mm) (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The substitute part SK101M035ST meets all critical electrical and mechanical parameters, with the exception of maximum seated height, which is 0.531" (13.50mm) compared to 0.413" (10.50mm) for the primary part. This dimensional difference must be evaluated against specific board layout constraints.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: 107SAK035M

Use the 107SAK035M when board layout requires the minimum seated height of 0.413" (10.50mm). This part is Active status, ROHS3 compliant, and carries 1087 units in current inventory.

Substitute Part: SK101M035ST

The SK101M035ST is electrically and functionally equivalent to the 107SAK035M across all critical parameters: capacitance, voltage rating, tolerance, lifetime, operating temperature range, and compliance certifications. Both parts are manufactured within the Cornell Dubilier family and are ROHS3 compliant with MSL 1 (Unlimited).

The SK101M035ST exhibits lower ESR (1.59 Ohm versus 2.321 Ohm @ 120Hz), which represents improved performance characteristics. However, the substitute part has a maximum seated height of 0.531" (13.50mm), which is 0.118" (3.00mm) taller than the primary part.

Selection Criteria:

• If board layout accommodates the taller profile, SK101M035ST is a direct substitute with superior ESR performance and higher inventory availability (1462 units).
• If board layout is constrained to 0.413" (10.50mm) maximum height, the 107SAK035M is the required selection.
• Both parts meet identical compliance requirements (ROHS3, REACH Unaffected, EAR99, HTSUS 8532.22.0020).

Frequently Asked Questions (FAQ)

Q: Can SK101M035ST replace 107SAK035M in all applications?

A: SK101M035ST is electrically equivalent and meets all electrical specifications. The primary consideration is physical height: SK101M035ST is 0.118" (3.00mm) taller. Verify board layout clearance before substitution.

Q: What is the difference in ESR between these parts?

A: The 107SAK035M has ESR of 2.321 Ohm @ 120Hz, while SK101M035ST has ESR of 1.59 Ohm. Lower ESR in SK101M035ST indicates reduced heat generation and improved ripple current handling capability.

Q: Are both parts RoHS compliant?

A: Yes. Both 107SAK035M and SK101M035ST are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

Q: Do these parts have identical lead spacing?

A: Yes. Both parts have lead spacing of 0.138" (3.50mm) and can diameter of 0.315" (8.00mm), ensuring identical PCB footprint compatibility.

Q: What is the moisture sensitivity level for both parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can I use SK101M035ST if my design specifies 107SAK035M?

A: Substitution is permissible only if board layout accommodates the increased height of 0.531" (13.50mm). Verify clearance above the component location before implementation.
