Substitute Part Grouping Explanation

Substitution of the KZE100VB681MM35LL is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 680 µF (exact match required)
• Voltage rating: 100 V (exact match required)
• Tolerance: ±20% (exact match required)
• Operating temperature range: -40°C ~ 105°C (exact match required)
• Ripple current specifications: 1.32 A @ 120 Hz and 2.2 A @ 100 kHz (exact match required)
• Impedance: 27 mOhms (exact match required)

Mechanical Equivalence Criteria:

• Mounting type: Through Hole (exact match required)
• Package configuration: Radial, Can (exact match required)
• Polarization: Polar (exact match required)

The substitute part EKZE101ELL681MMP1S meets all electrical and mechanical equivalence criteria. The primary distinction is product status: the main part is obsolete while the substitute is active, with reduced lifetime specification (5,000 hours versus 10,000 hours at 105°C).

Parameter Comparison

Engineering Selection Recommendations

The EKZE101ELL681MMP1S is the direct active equivalent for the obsolete KZE100VB681MM35LL. Both components are manufactured by Chemi-Con and share identical electrical specifications across capacitance, voltage rating, tolerance, operating temperature range, ripple current ratings, and impedance characteristics.

Compliance Considerations:

The substitute part EKZE101ELL681MMP1S carries ROHS3 compliance certification, whereas the main part is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulatory requirements. Both parts maintain REACH Unaffected status and EAR99 export classification.

Lifetime Specification:

The substitute part specifies 5,000 hours at 105°C compared to the main part's 10,000-hour rating. This reduced lifetime must be evaluated against application requirements and thermal operating conditions. For applications requiring extended operational life at elevated temperatures, this parameter difference requires assessment.

Availability and Production Status:

The substitute part is currently in active production with 3,144 units in stock, ensuring supply continuity. The main part, classified as obsolete with 731 units available, presents long-term supply risk for new production or system refresh cycles.

Frequently Asked Questions (FAQ)

Q: Can EKZE101ELL681MMP1S directly replace KZE100VB681MM35LL in existing designs?

A: Yes. Both components share identical electrical parameters: 680 µF capacitance, 100 V voltage rating, ±20% tolerance, -40°C to 105°C operating range, 1.32 A ripple current at 120 Hz, 2.2 A ripple current at 100 kHz, and 27 mOhms impedance. Both are through-hole mounted radial can packages with polar configuration. Physical dimensions are compatible for PCB mounting.

Q: What is the significance of the lifetime rating difference?

A: The main part specifies 10,000 hours at 105°C while the substitute specifies 5,000 hours at 105°C. This represents a 50% reduction in rated operational life under maximum temperature conditions. Applications operating continuously at or near 105°C ambient temperature should evaluate this parameter against system design life requirements.

Q: Are there compliance differences between these parts?

A: Yes. The substitute part EKZE101ELL681MMP1S is ROHS3 compliant, while the main part KZE100VB681MM35LL is RoHS non-compliant. For applications subject to RoHS directives or customer requirements, the substitute part provides regulatory compliance. Both parts are REACH Unaffected and classified as EAR99 for export purposes.

Q: What are the physical dimensions of the substitute part?

A: The EKZE101ELL681MMP1S has a lead spacing of 0.295 inches (7.50 mm), diameter of 0.709 inches (18.00 mm), and maximum seated height of 1.457 inches (37.00 mm). These dimensions are standard for radial can packages in this capacitance and voltage class.

Q: Is the substitute part available for immediate procurement?

A: Yes. The EKZE101ELL681MMP1S is classified as active product status with 3,144 units in stock. The main part, classified as obsolete, has limited inventory of 731 units and presents supply discontinuation risk.

Q: Are there any electrical performance differences between these parts?

A: No. Both components are electrically identical across all specified parameters: capacitance, voltage rating, tolerance, temperature range, ripple current ratings, and impedance. Electrical performance in circuit operation is equivalent.
