Key Parameters

Substitute Part Grouping Explanation

Substitution of the SXR680M063ST is determined by strict equivalence in the following electrical and mechanical parameters:

Primary Equivalence Criteria:

• Capacitance value: 68 µF (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: 5.00 mm (exact match required)
• Diameter: 10.00 mm (exact match required)

Allowable Variation Parameters:

• Voltage rating: Substitute parts must equal or exceed 63 V
• ESR: Substitute parts may differ; lower ESR values are acceptable
• Lifetime @ 105°C: Substitute parts may equal or exceed 4000 Hrs
• Ripple current: Substitute parts may equal or exceed specified values
• Height: Substitute parts may exceed 16.00 mm within PCB layout constraints
• Operating temperature range: Must maintain -40°C to 105°C minimum

Two substitute parts meet these criteria and are identified below.

Engineering Selection Recommendations

EKZE101ELL680MJ16S (Chemi-Con KZE Series)

This substitute is classified as Active product status, indicating current manufacturing and long-term availability. The EKZE101ELL680MJ16S maintains electrical equivalence with the SXR680M063ST across all critical parameters: 68 µF capacitance, ±20% tolerance, through-hole radial configuration, and 5.00 mm lead spacing. The rated voltage is increased to 100 V, providing enhanced voltage margin. The component achieves 4000 Hrs lifetime at 105°C, matching the original specification. Physical dimensions are compatible with existing PCB layouts, with height increased to 17.50 mm. ROHS3 compliance and REACH Unaffected status confirm regulatory alignment. This part is suitable for direct replacement in production environments.

UHE2A680MPD (Nichicon UHE Series)

This substitute carries Not For New Designs product status, indicating the manufacturer has discontinued active promotion for new applications. The UHE2A680MPD provides electrical equivalence in capacitance, tolerance, and through-hole radial package. Voltage rating is increased to 100 V. The component offers extended lifetime of 7000 Hrs at 105°C, exceeding the original 4000 Hrs specification. Physical dimensions match the original part exactly at 16.00 mm height. ROHS3 compliance is confirmed; however, REACH Affected status indicates regulatory restrictions in certain jurisdictions. This part is suitable for replacement in existing production only where regulatory constraints do not apply.

Frequently Asked Questions (FAQ)

Q: Can EKZE101ELL680MJ16S replace SXR680M063ST in all applications?

A: Yes. The EKZE101ELL680MJ16S meets all electrical and mechanical equivalence criteria. The increased voltage rating (100 V vs. 63 V) and identical capacitance (68 µF) ensure functional compatibility. The height increase to 17.50 mm must be verified against PCB layout constraints.

Q: What is the difference between the two substitute parts?

A: Both substitutes provide 68 µF capacitance at ±20% tolerance in identical through-hole radial packages. EKZE101ELL680MJ16S is Active status with 4000 Hrs lifetime. UHE2A680MPD is Not For New Designs status with extended 7000 Hrs lifetime. EKZE101ELL680MJ16S is recommended for new production due to active manufacturer support.

Q: Does the increased voltage rating affect circuit performance?

A: No. Substitute parts rated at 100 V are electrically compatible in circuits designed for 63 V operation. The higher voltage rating provides additional safety margin without altering capacitance or performance characteristics.

Q: Are there height compatibility concerns?

A: EKZE101ELL680MJ16S has maximum seated height of 17.50 mm, compared to 16.00 mm for the original SXR680M063ST. Verify PCB layout clearance before substitution. UHE2A680MPD maintains the original 16.00 mm height.

Q: What is the significance of product status classifications?

A: Active status (EKZE101ELL680MJ16S) indicates ongoing manufacturing and long-term availability. Not For New Designs status (UHE2A680MPD) indicates the manufacturer no longer promotes the part for new applications, though existing inventory may be available. Obsolete status (SXR680M063ST) indicates the original part is no longer manufactured.

Q: Are both substitutes RoHS compliant?

A: Yes. Both EKZE101ELL680MJ16S and UHE2A680MPD are ROHS3 Compliant. The original SXR680M063ST is also ROHS3 Compliant.

Q: What is the REACH status difference between substitutes?

A: EKZE101ELL680MJ16S is REACH Unaffected, indicating no regulatory restrictions in REACH-regulated jurisdictions. UHE2A680MPD is REACH Affected, indicating potential restrictions in certain regions. Verify regulatory requirements for your application location.
