SR071A471KAATR2 Equivalent & Substitute Parts

Part Overview

The SR071A471KAATR2 is a 470 pF ceramic capacitor rated at 100V with C0G/NP0 temperature coefficient, manufactured by KYOCERA AVX as part of the SkyCap® SR series. This through-hole radial capacitor 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. Substitute parts are identified when electrical specifications remain identical while physical packaging or lead configuration differs, enabling component selection based on board layout constraints or inventory availability.

Substitute Part Grouping Explanation

Substitution eligibility for the SR071A471KAATR2 is determined by strict equivalence in the following electrical parameters: capacitance value (470 pF), tolerance (±10%), voltage rating (100V), and temperature coefficient (C0G/NP0). All substitute parts must maintain identical electrical performance across the specified operating temperature range (-55°C to 125°C).

Physical differences that permit substitution include:

Lead configuration (formed/kinked versus straight leads)
Package dimensions and height
Lead spacing
Packaging format (tape/reel versus bulk)

The identified substitutes SR151A471KAR and SR211A471KAR meet all electrical equivalence criteria while differing in physical form factor and lead geometry.

Engineering Selection Recommendations

All three parts—SR071A471KAATR2, SR151A471KAR, and SR211A471KAR—are electrically equivalent and suitable for applications requiring 470 pF capacitance at 100V with C0G/NP0 stability. Selection between these parts depends on board layout requirements and lead spacing constraints.

SR071A471KAATR2 features formed/kinked leads with the smallest footprint (0.100" lead spacing, 0.100" seated height) and is supplied in tape/reel packaging.

SR151A471KAR provides identical electrical performance with straight leads, slightly increased seated height (0.150"), and bulk packaging. The straight lead configuration may simplify insertion in certain assembly processes.

SR211A471KAR maintains full electrical equivalence with larger physical dimensions (0.200" lead spacing, 0.200" seated height) and formed/kinked leads. This variant accommodates board designs with wider lead spacing requirements.

All parts maintain ROHS3 compliance and active production status, ensuring long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Are SR071A471KAATR2, SR151A471KAR, and SR211A471KAR electrically interchangeable?

A: Yes. All three parts deliver identical electrical performance: 470 pF capacitance, ±10% tolerance, 100V rating, and C0G/NP0 temperature coefficient across -55°C to 125°C. Substitution is valid from an electrical standpoint.

Q: What determines which substitute part to select?

A: Physical form factor and board layout. SR071A471KAATR2 and SR151A471KAR share 0.100" lead spacing and identical body dimensions but differ in lead style (kinked versus straight) and seated height. SR211A471KAR requires 0.200" lead spacing and accommodates larger board layouts. Select based on your PCB hole pattern and available space.

Q: Can I use SR211A471KAR as a direct replacement for SR071A471KAATR2?

A: Only if your PCB design accommodates 0.200" lead spacing. The larger footprint and increased seated height (0.200" versus 0.100") may not fit existing board layouts designed for the SR071A471KAATR2.

Q: What is the difference between formed/kinked leads and straight leads?

A: Lead style affects insertion and assembly. Formed/kinked leads (SR071A471KAATR2 and SR211A471KAR) are pre-bent for specific hole spacing. Straight leads (SR151A471KAR) require manual bending or automated forming during assembly. Both styles are functionally equivalent once installed.

Q: Are packaging differences significant for component selection?

A: Packaging (tape/reel versus bulk) affects supply chain logistics and handling but does not impact electrical performance or board-level compatibility. Select based on your procurement and assembly requirements.

Q: Do all three parts meet the same compliance standards?

A: Yes. SR071A471KAATR2, SR151A471KAR, and SR211A471KAR are all ROHS3 compliant with REACH unaffected status and EAR99 classification. Compliance requirements do not differentiate these parts.
