SR271A331JAR Equivalent & Substitute Parts

Part Overview

The SR271A331JAR is a 330 pF ±5% 100V ceramic capacitor manufactured by KYOCERA AVX in the SkyCap® SR series. This radial through-hole component features C0G/NP0 temperature coefficient characteristics suitable for general-purpose applications across the -55°C to 125°C operating range. The part is ROHS3 compliant and currently active in production.

Substitute parts become necessary when the original SR271A331JAR is unavailable due to inventory constraints, supply chain disruptions, or when alternative packaging formats better suit manufacturing requirements. Equivalent components must maintain identical electrical specifications while accommodating variations in physical dimensions and lead configurations within acceptable design tolerances.

Substitute Part Grouping Explanation

Substitution eligibility for the SR271A331JAR is determined by strict adherence to the following electrical and mechanical parameters:

Electrical Equivalence Requirements:

Capacitance: 330 pF (exact match)
Tolerance: ±5% (exact match)
Voltage Rating: 100V (exact match or higher)
Temperature Coefficient: C0G/NP0 (exact match)
Operating Temperature: -55°C ~ 125°C (exact match or wider range)

Mechanical Compatibility Criteria:

Mounting Type: Through Hole (exact match)
Package / Case: Radial (exact match)
Lead Style: Formed Leads or Straight (both acceptable for through-hole radial packages)
Lead Spacing: Variations permitted within PCB design tolerance (0.100" to 0.300")
Physical Dimensions: Variations permitted provided component fits within allocated board space

Compliance Requirements:

RoHS3 Compliant (mandatory)
REACH Unaffected (mandatory)

All substitute parts listed below meet these criteria and are direct functional equivalents for the SR271A331JAR.

Engineering Selection Recommendations

Primary Substitutes (Active Status, Bulk Packaging): SR151A331JAR and C315C331J1G5TA are preferred substitutes when the original SR271A331JAR is unavailable. Both parts maintain active production status and are available in bulk packaging. SR151A331JAR is manufactured by the same supplier (KYOCERA AVX) and offers identical electrical specifications with reduced lead spacing (0.100"). C315C331J1G5TA from KEMET provides equivalent performance with the GoldMax 300 Comm C0G series designation and low ESL characteristics.

Secondary Substitutes (Active Status, Alternative Packaging): SR151A331JARTR1, RDE5C2A331J0M1H03A, and RDE5C2A331J0S1H03A are active alternatives available in cut tape packaging. These parts are suitable for automated assembly processes and high-volume production environments. Lead spacing variations (0.100" to 0.098") require PCB design verification to ensure compatibility with existing footprints.

Conditional Substitute (Not For New Designs): FK28C0G2A331JN000 from TDK Corporation meets all electrical and mechanical equivalence criteria but carries "Not For New Designs" status. This part is suitable only for legacy system maintenance or repair applications where the original specification must be maintained. New designs should not incorporate this component.

Lead Configuration Considerations: C317C331J1G5TA features formed leads with 0.200" spacing, matching the original SR271A331JAR lead spacing more closely than straight-lead alternatives. This configuration minimizes PCB layout modifications when direct replacement is required.
