Key Parameters

Substitute Part Grouping Explanation

Substitution of the KXG450VB6R8M10X20LL is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 6.8 µF (exact match required)
• Rated voltage: 450 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime rating: 8000 Hrs @ 105°C (exact match required)
• Operating temperature range: -25°C ~ 105°C (exact match required)
• Ripple current specifications: 110 mA @ 120 Hz and 275 mA @ 100 kHz (exact match required)

Mechanical Parameters:

• Lead spacing: 0.197" (5.00 mm) (exact match required)
• Diameter: 0.394" (10.00 mm) (exact match required)
• Height: 0.787" (20.00 mm) (exact match required)
• Mounting type: Through Hole (exact match required)
• Package type: Radial, Can (exact match required)

Substitute parts must satisfy all electrical and mechanical parameters listed above to ensure functional and physical compatibility within the original application circuit and PCB layout.

Parameter Comparison

Engineering Selection Recommendations

The EKXG451ELL6R8MJ20S is a direct parametric equivalent to the KXG450VB6R8M10X20LL. All electrical and mechanical specifications are identical, ensuring functional compatibility and PCB-level interchangeability.

Key Selection Factors:

Product Status: The KXG450VB6R8M10X20LL is obsolete, while the EKXG451ELL6R8MJ20S maintains active product status with significantly higher inventory availability (17,900 pieces versus 863 pieces). This difference is material for production planning and long-term supply chain security.

Regulatory Compliance: The EKXG451ELL6R8MJ20S is ROHS3 compliant, whereas the KXG450VB6R8M10X20LL is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, the EKXG451ELL6R8MJ20S is the appropriate selection.

Packaging: The KXG450VB6R8M10X20LL is supplied in standard packaging, while the EKXG451ELL6R8MJ20S is supplied in bulk packaging. Packaging selection depends on procurement volume and handling requirements.

Both parts are REACH Unaffected and classified under ECCN EAR99 and HTSUS 8532.22.0020, indicating equivalent regulatory treatment for export and trade purposes.

Frequently Asked Questions (FAQ)

Q: Can the EKXG451ELL6R8MJ20S be used as a direct replacement for the KXG450VB6R8M10X20LL in existing designs?

A: Yes. The EKXG451ELL6R8MJ20S is a direct parametric equivalent. All electrical specifications (capacitance, voltage, tolerance, ripple current, temperature range, and lifetime) and mechanical dimensions (lead spacing, diameter, height) are identical. No circuit modifications or PCB layout changes are required.

Q: What is the significance of the product status difference between these parts?

A: The KXG450VB6R8M10X20LL is classified as obsolete, indicating that the manufacturer has discontinued production and support. The EKXG451ELL6R8MJ20S is active, meaning it is currently manufactured and supported. For new designs or ongoing production, the active part is the appropriate choice.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both parts deliver identical electrical characteristics. However, if your application or customer requirements mandate RoHS compliance, the EKXG451ELL6R8MJ20S must be selected.

Q: Are there any differences in packaging that affect component handling or installation?

A: The KXG450VB6R8M10X20LL uses standard packaging, while the EKXG451ELL6R8MJ20S uses bulk packaging. Both are suitable for through-hole assembly. Bulk packaging is typically used for higher-volume orders and may offer cost advantages. Component handling and installation procedures remain identical.

Q: What parameters must match exactly for substitution to be valid?

A: All of the following parameters must match exactly: capacitance (6.8 µF), rated voltage (450 V), tolerance (±20%), lifetime rating (8000 Hrs @ 105°C), operating temperature range (-25°C ~ 105°C), ripple current specifications (110 mA @ 120 Hz and 275 mA @ 100 kHz), lead spacing (5.00 mm), diameter (10.00 mm), height (20.00 mm), mounting type (through hole), and package type (radial, can). Any deviation in these parameters indicates the parts are not equivalent.

Q: Is inventory availability a factor in component selection?

A: Inventory availability is a supply chain consideration but not an electrical or mechanical compatibility factor. The EKXG451ELL6R8MJ20S has significantly higher inventory (17,900 pieces) compared to the KXG450VB6R8M10X20LL (863 pieces). For production planning and lead time management, the higher inventory of the active part provides supply chain advantages.
