SR071A331KAATR2 Equivalent & Substitute Parts

Part Overview

The SR071A331KAATR2 is a 330 pF ceramic capacitor rated at 100V with C0G/NP0 temperature coefficient, manufactured by KYOCERA AVX as part of 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 currently active in production with ROHS3 compliance and REACH unaffected status. Equivalent and substitute parts are identified when identical electrical specifications and compatible mechanical configurations are available from the same manufacturer, enabling procurement flexibility and supply chain continuity.

Substitute Part Grouping Explanation

Substitution for the SR071A331KAATR2 is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance value: 330 pF
• Tolerance: ±10%
• Voltage rating: 100V
• Temperature coefficient: C0G/NP0
• Operating temperature range: -55°C to 125°C
• Mounting type: Through Hole Radial
• Lead spacing: 0.100" (2.54mm)
• Compliance certifications: ROHS3, REACH unaffected

The SR151A331KAR meets all substitution criteria. Variations in lead style (kinked versus straight) and physical height do not affect electrical performance or circuit board compatibility when lead spacing remains constant at 0.100" (2.54mm).

Parameter Comparison

Engineering Selection Recommendations

Both SR071A331KAATR2 and SR151A331KAR are active production parts with identical electrical specifications and full regulatory compliance. Selection between these parts is based on mechanical fit requirements:

• SR071A331KAATR2 with kinked leads and 0.100" seated height is suitable for compact board layouts with minimal vertical clearance.
• SR151A331KAR with straight leads and 0.150" seated height accommodates standard through-hole insertion and is compatible with automated assembly processes.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current and future applications. Lead style and height differences do not affect electrical performance when lead spacing of 0.100" (2.54mm) is maintained.

Frequently Asked Questions (FAQ)

Q: Can SR151A331KAR replace SR071A331KAATR2 in existing designs?

A: Yes. Both parts have identical electrical specifications: 330 pF capacitance, ±10% tolerance, 100V rating, and C0G/NP0 temperature coefficient. The difference in lead style (straight versus kinked) and seated height (0.150" versus 0.100") does not affect electrical function. Board layout must accommodate the 0.150" maximum seated height of SR151A331KAR.

Q: What is the significance of lead style differences?

A: Lead style affects mechanical insertion and board layout. Kinked leads (SR071A331KAATR2) are pre-formed for compact spacing. Straight leads (SR151A331KAR) require manual forming or are compatible with standard through-hole insertion equipment. Electrical performance is identical.

Q: Are both parts suitable for high-reliability applications?

A: Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Both maintain stable capacitance across -55°C to 125°C operating range with C0G/NP0 temperature coefficient, suitable for general-purpose applications.

Q: What is the lead spacing requirement for substitution?

A: Lead spacing must remain at 0.100" (2.54mm) for direct substitution. This dimension determines board hole pattern compatibility and is identical for both SR071A331KAATR2 and SR151A331KAR.

Q: Can these parts be used interchangeably in automated assembly?

A: SR151A331KAR with straight leads is optimized for automated through-hole insertion equipment. SR071A331KAATR2 with kinked leads may require manual insertion or equipment adjustment. Verify assembly process compatibility before substitution.
