SR071A331JART Equivalent & Substitute Parts

Part Overview

The SR071A331JART is a 330 pF ±5% 100V ceramic capacitor with C0G/NP0 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 currently active and ROHS3 compliant.

Substitute parts are necessary when the original SR071A331JART becomes unavailable due to inventory constraints, supply chain disruptions, or when alternative packaging formats better suit production requirements. Equivalent parts must maintain identical electrical specifications and mechanical compatibility within the allowed parameter tolerances.

Engineering Selection Recommendations

Preferred Substitutes (Active Status):

SR151A331JAR and SR151A331JARTR1 are the primary recommended substitutes. Both are manufactured by KYOCERA AVX, the original manufacturer, and maintain active product status. SR151A331JARTR1 offers the highest inventory availability at 4441 pieces in Cut Tape format, suitable for automated assembly processes. SR151A331JAR provides bulk packaging with 2812 pieces available.

C315C331J1G5TA and C317C331J1G5TA are active KEMET alternatives with full ROHS3 compliance. C315C331J1G5TA maintains the 0.100" lead spacing of the original part, while C317C331J1G5TA features 0.200" lead spacing for applications requiring wider spacing.

RDE5C2A331J0M1H03A is an active Murata Electronics substitute available in Cut Tape format with 2881 pieces in stock. This part features 0.197" lead spacing and is suitable for production environments requiring tape-and-reel packaging.

Legacy Substitutes (Not For New Designs):

FK18C0G2A331JN020 and FK28C0G2A331JN000 are TDK Corporation parts marked as Not For New Designs. These parts remain electrically equivalent but should be used only for legacy system maintenance or repair applications where original part sourcing is unavailable. Both maintain ROHS3 compliance and full electrical specification matching.

Selection Criteria:

Choose substitutes based on: (1) production packaging requirements (Bulk, Cut Tape, or Tape & Reel), (2) lead spacing compatibility with PCB layout, (3) product status alignment with design phase (active for new designs, legacy parts for maintenance), and (4) inventory availability for production volume requirements.

Frequently Asked Questions (FAQ)

Q: Can SR151A331JAR be used as a direct replacement for SR071A331JART?

A: Yes. Both parts are electrically identical with matching capacitance (330 pF), tolerance (±5%), voltage rating (100V), temperature coefficient (C0G/NP0), and operating temperature range (-55°C to 125°C). The primary difference is lead style: SR071A331JART uses formed leads with kinked configuration, while SR151A331JAR uses straight leads. Both are through-hole radial packages suitable for PCB mounting.

Q: What is the difference between C315C331J1G5TA and C317C331J1G5TA?

A: Both are KEMET equivalents with identical electrical specifications. The key difference is lead spacing: C315C331J1G5TA has 0.100" (2.54mm) lead spacing matching the original SR071A331JART, while C317C331J1G5TA has 0.200" (5.08mm) lead spacing. Select based on PCB hole pattern requirements.

Q: Are TDK FK series parts suitable for new product designs?

A: No. FK18C0G2A331JN020 and FK28C0G2A331JN000 are marked as Not For New Designs. These parts are electrically equivalent but should be reserved for legacy system maintenance or repair applications only. For new designs, use active-status alternatives such as SR151A331JAR, C315C331J1G5TA, or RDE5C2A331J0M1H03A.

Q: What packaging formats are available for substitute parts?

A: Substitute parts are available in three packaging formats: Bulk (loose components), Cut Tape (CT) for semi-automated assembly, and Tape & Reel for fully automated pick-and-place systems. SR151A331JARTR1 and RDE5C2A331J0M1H03A are available in Cut Tape format. SR151A331JAR, C315C331J1G5TA, C317C331J1G5TA, and TDK parts are available in Bulk format.

Q: Do all substitute parts meet ROHS3 compliance?

A: Yes. All listed substitute parts are ROHS3 compliant, matching the compliance status of the original SR071A331JART. All parts are also REACH Unaffected and classified as EAR99 for export purposes.

Q: Can lead spacing variations affect circuit performance?

A: Lead spacing variations do not affect electrical performance of the capacitor itself. However, they impact PCB layout compatibility. Verify that selected substitute parts match your PCB hole pattern spacing before procurement. Parts with 0.100" spacing are compatible with standard 0.1" grid layouts, while 0.197" and 0.200" spacing variants require corresponding PCB design.
