SR122C102KAATR1 Equivalent & Substitute Parts

Part Overview

The SR122C102KAATR1 is a 1000 pF ceramic capacitor rated at 200V with X7R temperature coefficient, manufactured by KYOCERA AVX in the SkyCap® SR series. This radial through-hole component is designed for general-purpose applications and is currently active in production. Substitute parts are necessary when the original part becomes unavailable, when alternative packaging formats are required, or when inventory constraints necessitate sourcing from alternative manufacturers while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

All substitute parts listed maintain identical electrical specifications: 1000 pF capacitance, ±10% tolerance, 200V voltage rating, and X7R temperature coefficient with -55°C to 125°C operating range. All substitutes are KEMET GoldMax 300 Comm X7R series components with ROHS3 compliance and EAR99 ECCN classification.

Substitution is determined by the following allowed parameters:

Capacitance value (1000 pF)
Voltage rating (200V)
Temperature coefficient (X7R)
Tolerance (±10%)
Mounting type (Through Hole Radial)
Compliance certifications (ROHS3, REACH Unaffected)

Variations in physical dimensions, lead spacing, lead style, and packaging format do not affect electrical substitutability but must be evaluated for mechanical fit within the target application.

Engineering Selection Recommendations

All listed substitute parts maintain full electrical equivalence to the SR122C102KAATR1. Selection among substitutes should be based on:

Mechanical Compatibility: The SR122C102KAATR1 features 0.200" (5.08mm) lead spacing with formed leads. Substitutes C317C102K2R5TA and C322C102K2R5TA maintain identical 0.200" lead spacing with formed leads, providing direct mechanical compatibility. Substitutes C315C102K2R5TA, C315C102K2R5TA7301, and C320C102K2R5TA feature 0.100" (2.54mm) lead spacing with straight leads and require PCB layout modification.

Packaging Format: The original part is supplied in Tape & Reel (TR) format. Substitute C315C102K2R5TA7301 is available in Cut Tape (CT) format. Remaining substitutes are supplied in Bulk packaging. Packaging selection depends on assembly process requirements and inventory management practices.

Inventory Availability: All substitute parts are in active production with confirmed stock levels ranging from 1,480 to 13,693 pieces.

Compliance: All substitutes maintain ROHS3 compliance and REACH Unaffected status, matching the original part's regulatory standing.

Frequently Asked Questions (FAQ)

Q: Are all listed parts electrically interchangeable with the SR122C102KAATR1?

A: Yes. All substitute parts share identical capacitance (1000 pF), tolerance (±10%), voltage rating (200V), temperature coefficient (X7R), and operating temperature range (-55°C to 125°C). Electrical performance is equivalent across all listed parts.

Q: What is the primary difference between substitute options?

A: Physical dimensions, lead spacing, lead style, and packaging format differ among substitutes. The SR122C102KAATR1 has 0.200" lead spacing with formed leads. C317C102K2R5TA and C322C102K2R5TA maintain this spacing and lead style. C315C102K2R5TA, C315C102K2R5TA7301, and C320C102K2R5TA have 0.100" lead spacing with straight leads, requiring PCB layout changes.

Q: Can I use a substitute with different lead spacing on the same PCB?

A: No. Lead spacing differences require PCB modification. Direct substitution without layout changes is only possible with C317C102K2R5TA or C322C102K2R5TA, which maintain 0.200" spacing and formed leads.

Q: Which substitute offers the closest physical match to the original part?

A: C317C102K2R5TA and C322C102K2R5TA both maintain 0.200" lead spacing and formed leads. C317C102K2R5TA has a maximum seated height of 0.200" (5.08mm), while C322C102K2R5TA has 0.260" (6.60mm). The original SR122C102KAATR1 has a maximum seated height of 0.100" (2.54mm).

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH Unaffected, matching the original part's regulatory compliance status.

Q: What packaging options are available for substitutes?

A: C315C102K2R5TA7301 is supplied in Cut Tape (CT) format. C315C102K2R5TA, C317C102K2R5TA, C320C102K2R5TA, and C322C102K2R5TA are supplied in Bulk packaging. The original SR122C102KAATR1 is supplied in Tape & Reel (TR) format.
