Substitute Part Grouping Explanation

Substitution of the KXG160VB331M18X31LL is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 160 V (exact match required)
• Tolerance: ±20% (exact match required)
• Ripple Current specifications: 1.39 A @ 120 Hz and 3.1275 A @ 100 kHz (exact match required)
• Lifetime rating: 10000 Hrs @ 105°C (exact match required)
• Operating temperature range: -40°C ~ 105°C (exact match required)

Mechanical Parameters:

• Lead spacing: 0.295" (7.50 mm) (exact match required)
• Diameter: 0.709" (18.00 mm) (exact match required)
• Height: 1.240" (31.50 mm) (exact match required)
• Package type: Radial, Can through-hole (exact match required)

Manufacturer Consistency:

• Series designation: KXG (maintained across substitutes)
• Manufacturer: Chemi-Con (same manufacturer preferred for consistency)

Substitute parts must satisfy all electrical and mechanical parameters without deviation to ensure direct interchangeability in existing PCB designs and circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The EKXG161ELL331MMN3S is a direct parametric equivalent to the KXG160VB331M18X31LL. All electrical and mechanical specifications are identical, ensuring pin-for-pin and form-factor compatibility.

Compliance Improvement: The substitute part is ROHS3 compliant, compared to the non-compliant status of the original part. This provides enhanced environmental and regulatory alignment for applications subject to RoHS directives.

Inventory Availability: The substitute part is available in significantly higher quantities (3278 Pcs) compared to the original part (802 Pcs), supporting both immediate and sustained procurement requirements.

Packaging Consideration: The substitute is supplied in bulk packaging, which may require internal repackaging for applications requiring specific packaging formats.

Frequently Asked Questions (FAQ)

Q: Can EKXG161ELL331MMN3S be used as a direct replacement for KXG160VB331M18X31LL?

A: Yes. All electrical parameters (capacitance, voltage rating, tolerance, ripple current, lifetime, and operating temperature) and mechanical parameters (lead spacing, diameter, height, and mounting type) are identical. The substitute is a direct interchangeable replacement.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and compliance certification. The KXG160VB331M18X31LL is obsolete and RoHS non-compliant. The EKXG161ELL331MMN3S is an active product with ROHS3 compliance. All functional specifications remain identical.

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

A: No. Both parts share identical electrical specifications including capacitance (330 µF), voltage rating (160 V), tolerance (±20%), ripple current ratings, and thermal lifetime (10000 Hrs @ 105°C). Circuit performance is equivalent.

Q: Will the substitute fit in existing PCB designs?

A: Yes. Both parts are radial, can-type capacitors with identical lead spacing (0.295" / 7.50 mm), diameter (0.709" / 18.00 mm), and height (1.240" / 31.50 mm). PCB footprints and mounting holes require no modification.

Q: What is the significance of the RoHS3 compliance on the substitute?

A: ROHS3 compliance indicates the substitute meets current environmental and hazardous substance restrictions. This is relevant for applications subject to RoHS directives or customer requirements mandating compliant components.

Q: Is the bulk packaging of the substitute a limitation?

A: Bulk packaging affects procurement and internal logistics but does not impact component functionality or performance. Organizations requiring specific packaging formats may need to repackage the substitute internally.

Q: Are both parts suitable for the same temperature range applications?

A: Yes. Both parts operate across the identical temperature range of -40°C to 105°C with a rated lifetime of 10000 hours at 105°C, making them suitable for equivalent thermal environments.
