SR072C331KAATR1 Equivalent & Substitute Parts

Part Overview

The SR072C331KAATR1 is a 330 pF ceramic capacitor rated at 200V with X7R temperature coefficient, manufactured by KYOCERA AVX in the SkyCap® SR series. This through-hole radial 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. Equivalent and substitute parts are identified when identical electrical specifications and compatible mechanical parameters are available from alternative manufacturers.

Substitute Part Grouping Explanation

Substitute parts for the SR072C331KAATR1 are qualified based on the following criteria:

• Identical capacitance value: 330 pF
• Identical tolerance: ±10%
• Identical voltage rating: 200V
• Identical temperature coefficient: X7R
• Identical operating temperature range: -55°C ~ 125°C
• Compatible mounting type: Through Hole Radial
• Compatible lead spacing: 0.100" (2.54mm) or 0.200" (5.08mm)
• Equivalent RoHS and REACH compliance status

Two KEMET GoldMax 300 Comm X7R series parts meet these criteria with variations in lead style and height specifications.

Parameter Comparison

Engineering Selection Recommendations

Both KEMET substitute parts maintain full electrical equivalence to the SR072C331KAATR1 across all critical specifications: capacitance, tolerance, voltage rating, temperature coefficient, and operating temperature range. Both parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of the original component.

C315C331K2R5TA is the primary substitute, offering identical lead spacing (0.100" / 2.54mm) with straight lead style and a seated height of 0.183" (4.66mm). This part is suitable for applications where lead spacing compatibility is the primary concern.

C317C331K2R5TA provides an alternative with 0.200" (5.08mm) lead spacing and formed leads, with a maximum seated height of 0.200" (5.08mm). This part is applicable when wider lead spacing is required by the circuit board layout.

Selection between substitutes depends on PCB footprint requirements and available board space for component height.

Frequently Asked Questions (FAQ)

Q: Are C315C331K2R5TA and C317C331K2R5TA electrically identical to SR072C331KAATR1?

A: Yes. Both KEMET parts match the SR072C331KAATR1 in all electrical parameters: 330 pF capacitance, ±10% tolerance, 200V rating, X7R temperature coefficient, and -55°C to 125°C operating range.

Q: What is the primary difference between the two KEMET substitutes?

A: The primary differences are lead spacing and seated height. C315C331K2R5TA has 0.100" (2.54mm) lead spacing matching the original part, while C317C331K2R5TA has 0.200" (5.08mm) lead spacing. Seated heights differ accordingly: 0.183" (4.66mm) for C315C331K2R5TA and 0.200" (5.08mm) for C317C331K2R5TA.

Q: Can I use C317C331K2R5TA if my PCB is designed for 0.100" lead spacing?

A: No. C317C331K2R5TA has 0.200" (5.08mm) lead spacing and will not fit a PCB footprint designed for 0.100" (2.54mm) spacing. Use C315C331K2R5TA for direct footprint compatibility.

Q: Are there height restrictions I should consider?

A: The original SR072C331KAATR1 has a maximum seated height of 0.100" (2.54mm). Both substitutes are taller: C315C331K2R5TA at 0.183" (4.66mm) and C317C331K2R5TA at 0.200" (5.08mm). Verify available board clearance before selection.

Q: Do the substitutes maintain the same compliance certifications?

A: Yes. Both C315C331K2R5TA and C317C331K2R5TA are ROHS3 compliant and REACH unaffected, matching the regulatory status of SR072C331KAATR1.
