SR155A270KAATR2 Equivalent & Substitute Parts

Part Overview

The SR155A270KAATR2 is a 27 pF ceramic capacitor manufactured by KYOCERA AVX from the SkyCap® SR series. This radial through-hole component operates at 50V with C0G/NP0 temperature coefficient and ±10% capacitance tolerance. The part is actively produced and ROHS3 compliant, making it suitable for general-purpose applications requiring stable capacitance across the -55°C to 125°C operating range. Equivalent parts are identified when manufacturers discontinue production, inventory becomes limited, or design flexibility requires alternative sourcing options while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SR155A270KAATR2 is determined by the following critical parameters:

• Capacitance Value: Must be 27 pF (exact match required)
• Voltage Rating: Must be 50V or higher (equal or greater acceptable)
• Temperature Coefficient: Must be C0G or NP0 (equivalent specifications)
• Operating Temperature Range: Must cover -55°C to 125°C minimum
• Mounting Type: Must be through-hole radial configuration
• Lead Spacing: Tolerance of ±0.010" (0.25mm) acceptable for PCB compatibility
• Compliance: Must maintain ROHS3 and REACH compliance status

The identified substitute K270J15C0GF5TK2 meets all substitution criteria. While it features tighter ±5% tolerance compared to the original ±10%, this represents an improvement in capacitance stability and does not restrict compatibility. Physical dimensions and lead configuration remain within acceptable mechanical tolerances for standard PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

Both the SR155A270KAATR2 and K270J15C0GF5TK2 are active production components with full ROHS3 and REACH compliance. Selection between these parts should be based on:

• Inventory Availability: The K270J15C0GF5TK2 maintains higher stock levels (20,320 pcs vs. 990 pcs), providing supply chain flexibility
• Tolerance Requirements: Applications requiring tighter capacitance tolerance benefit from the K270J15C0GF5TK2 (±5% vs. ±10%)
• Lead Configuration: The K270J15C0GF5TK2 features kinked formed leads versus straight leads on the SR155A270KAATR2; verify PCB hole alignment and insertion tooling compatibility
• Packaging Format: The K270J15C0GF5TK2 is supplied in cut tape format; confirm compatibility with assembly processes

Both parts satisfy identical electrical specifications and environmental operating conditions.

Frequently Asked Questions (FAQ)

Q: Can K270J15C0GF5TK2 be used as a direct replacement for SR155A270KAATR2?

A: Yes. Both components share identical capacitance (27 pF), voltage rating (50V), temperature coefficient (C0G/NP0), and operating temperature range (-55°C to 125°C). The substitute features improved tolerance (±5% vs. ±10%), which does not restrict compatibility. Lead spacing differs by 0.002" (0.05mm), which is within standard PCB manufacturing tolerances.

Q: What is the difference between C0G and NP0 temperature coefficients?

A: C0G and NP0 are equivalent designations for the same temperature coefficient specification. Both indicate negligible capacitance change across the operating temperature range. The terminology varies by manufacturer region and standard (IEC vs. EIA).

Q: Does the tighter tolerance of the substitute part affect circuit performance?

A: No. The K270J15C0GF5TK2 tolerance of ±5% is a subset of the SR155A270KAATR2 tolerance of ±10%. Tighter tolerance provides improved capacitance stability and does not introduce incompatibility.

Q: Are there mechanical considerations when switching between these parts?

A: The K270J15C0GF5TK2 features kinked formed leads compared to straight leads on the SR155A270KAATR2. Lead spacing differs by 0.002" (0.05mm). Verify PCB hole positioning and insertion equipment compatibility before production changeover.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SR155A270KAATR2 and K270J15C0GF5TK2 are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.
