ARR06B105KWS Equivalent & Substitute Parts

Part Overview

The ARR06B105KWS is a 1 µF ±10% 50V ceramic capacitor with X7R temperature coefficient manufactured by KEMET in the ARR Indust X7R HT200C series. This through-hole radial component is designed for general-purpose applications requiring high-temperature operation across -55°C to 200°C. The part is currently active in production with 639 pieces available in stock. Equivalent and substitute parts are identified when electrical specifications (capacitance, voltage rating, tolerance, temperature coefficient) and mechanical parameters (mounting type, package style, lead configuration) align within acceptable engineering tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ARR06B105KWS is determined by strict alignment of the following parameters:

Electrical Compatibility Requirements:

• Capacitance value: 1 µF (exact match required)
• Voltage rating: 50V minimum (equal or higher acceptable)
• Tolerance: ±10% (exact match required)
• Temperature coefficient: X7R (exact match required)

Mechanical Compatibility Requirements:

• Mounting type: Through Hole (exact match required)
• Package style: Radial (exact match required)
• Lead spacing: 0.200" (5.08mm) (exact match required)
• Lead style: Straight (exact match required)

The substitute part SR305C105KAA meets all electrical and mechanical compatibility criteria. Both parts share identical capacitance, voltage rating, tolerance, temperature coefficient, mounting configuration, and lead spacing. Dimensional variations in body width (0.100" vs 0.125") do not affect circuit board layout compatibility for radial through-hole applications with 0.200" lead spacing.

Engineering Selection Recommendations

ARR06B105KWS Selection Criteria:

• Applications requiring sustained operation at temperatures above 125°C up to 200°C
• Designs where high-temperature performance is a functional requirement
• Systems where RoHS non-compliance is acceptable or not applicable

SR305C105KAA Selection Criteria:

• Applications operating within -55°C to 125°C temperature range
• Designs requiring ROHS3 compliance
• Equivalent electrical performance for general-purpose applications within the specified thermal envelope
• Higher inventory availability (1267 pieces vs 639 pieces)

Both parts are active products with identical electrical specifications and mechanical compatibility. Selection between them depends on application temperature requirements and regulatory compliance mandates. The operating temperature range difference is the primary technical distinction.

Frequently Asked Questions (FAQ)

Q: Can SR305C105KAA replace ARR06B105KWS in all applications?

A: SR305C105KAA is electrically and mechanically compatible for applications operating within -55°C to 125°C. Applications requiring sustained operation above 125°C must use ARR06B105KWS, as the substitute part is rated only to 125°C maximum.

Q: Are the physical dimensions compatible on the circuit board?

A: Yes. Both parts use identical lead spacing (0.200" / 5.08mm) and length (0.300" / 7.62mm). The body width difference (0.100" vs 0.125") does not affect through-hole PCB layout compatibility for radial components with this lead configuration.

Q: What is the significance of the X7R temperature coefficient?

A: X7R designates a ceramic capacitor with ±15% capacitance change across the operating temperature range. This specification is identical for both parts and ensures predictable performance across temperature extremes.

Q: Why does RoHS compliance differ between these parts?

A: ARR06B105KWS is RoHS non-compliant; SR305C105KAA is ROHS3 compliant. Selection depends on end-product regulatory requirements and market destination.

Q: Are lead spacing and lead style identical?

A: Yes. Both parts feature 0.200" (5.08mm) lead spacing and straight lead style, ensuring direct PCB footprint compatibility.

Q: What tolerance range applies to capacitance?

A: Both parts carry ±10% tolerance. At 1 µF nominal, acceptable capacitance range is 0.9 µF to 1.1 µF for either part.
