SR151C471KAATR2 Equivalent & Substitute Parts

Part Overview

The SR151C471KAATR2 is a 470 pF ceramic capacitor rated at 100V with X7R temperature coefficient, manufactured by KYOCERA AVX in the SkyCap® SR series. This radial through-hole component is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is ROHS3 compliant and currently in active production status with 1061 units available in stock.

Equivalent and substitute parts are identified when manufacturers discontinue production, inventory becomes limited, or design flexibility permits component sourcing from alternative suppliers while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical parameters:

• Capacitance value: 470 pF
• Tolerance: ±10%
• Voltage rating: 100V minimum
• Temperature coefficient: X7R
• Operating temperature range: -55°C to 125°C minimum
• Mounting type: Through Hole
• Package type: Radial
• Lead spacing: 0.100" (2.54mm)
• Compliance: ROHS3 Compliant

The identified substitute parts meet all core electrical specifications. Physical dimensions may vary within acceptable tolerances for through-hole radial components, provided lead spacing remains compatible with standard PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

All three components are ROHS3 compliant and maintain active production status. Selection between the main part and substitutes should be based on:

C315C471K1R5TA (KEMET GoldMax 300 Comm X7R): This substitute maintains identical lead spacing (0.100" / 2.54mm) and straight lead style, making it a direct mechanical and electrical replacement. Height difference (0.183" vs 0.150") is within acceptable tolerance for radial through-hole components. Inventory availability is higher at 4387 units.

K471K15X7RH5TH5 (Vishay Mono-Kap™ K): This substitute meets all electrical specifications but differs in physical configuration. Lead spacing is 0.197" (5.00mm) with formed leads and greater seated height (0.260"). This part requires PCB layout verification to confirm lead spacing compatibility before implementation.

Frequently Asked Questions (FAQ)

Q: Can C315C471K1R5TA be used as a direct replacement for SR151C471KAATR2?

A: Yes. Both parts share identical capacitance (470 pF), tolerance (±10%), voltage rating (100V), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), lead spacing (0.100" / 2.54mm), and lead style (straight). The height difference (0.183" vs 0.150") does not affect electrical performance or standard PCB mounting.

Q: Is K471K15X7RH5TH5 compatible with existing PCB layouts designed for SR151C471KAATR2?

A: Electrical compatibility is confirmed. Mechanical compatibility requires verification. The lead spacing differs (0.197" vs 0.100"), and formed leads may require layout adjustment. PCB hole spacing must be confirmed before substitution.

Q: What compliance certifications apply to all three parts?

A: All parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8532.24.0060.

Q: Are there packaging differences between these parts?

A: Yes. SR151C471KAATR2 is supplied in Tape & Reel (TR) packaging. C315C471K1R5TA is supplied in Bulk. K471K15X7RH5TH5 is supplied in Cut Tape (CT). Packaging selection depends on assembly process requirements and order quantities.
