SR071A271JART Equivalent & Substitute Parts

Part Overview

The SR071A271JART is a 270 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 and operates across -55°C to 125°C. The part is currently active in production with ROHS3 compliance and REACH unaffected status.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits alternative manufacturers while maintaining electrical and mechanical compatibility. The following equivalent components maintain identical electrical specifications and are qualified for direct substitution based on matching capacitance, voltage rating, temperature coefficient, and mounting compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters:

• Capacitance value: 270 pF (exact match required)
• Voltage rating: 100V (minimum acceptable)
• Temperature coefficient: C0G/NP0 (required for stability)
• Mounting type: Through Hole Radial (mechanical compatibility)
• Tolerance: ±5% (electrical performance match)
• Operating temperature range: -55°C ~ 125°C (environmental compatibility)

All qualified substitutes maintain these core electrical specifications. Physical dimensions and lead spacing may vary within acceptable PCB layout tolerances. Lead style variations (kinked vs. straight) and seated height differences do not affect electrical function but require verification against specific board layout constraints.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: SR151A271JAR (KYOCERA AVX)

SR151A271JAR is the manufacturer-recommended substitute from the same OEM. It maintains identical electrical specifications and ROHS3 compliance. The increased seated height (0.150" vs. 0.100") and straight lead style require PCB layout verification but present no electrical incompatibility. This part offers the highest inventory availability (2300 pcs) and active product status, ensuring long-term supply continuity.

Secondary Recommendations: RDE5C2A271J0K1H03B and RDE5C2A271J0S1H03A (Murata Electronics)

Both Murata RDE series parts maintain full electrical equivalence with active product status and ROHS3 compliance. RDE5C2A271J0K1H03B features 0.197" lead spacing with 0.236" seated height. RDE5C2A271J0S1H03A offers 0.098" lead spacing with identical seated height. Lead spacing selection depends on PCB footprint requirements. Combined inventory exceeds 4500 pcs, providing robust supply availability.

Alternative Options: FK18C0G2A271JN020 and FK28C0G2A271JN000 (TDK Corporation)

Both TDK FK series parts carry "Not For New Designs" status, indicating discontinued or legacy product lines. While electrically equivalent and ROHS3 compliant, these parts are suitable only for legacy system maintenance or repair applications where supply from active product lines is unavailable. FK18C0G2A271JN020 provides 0.098" lead spacing; FK28C0G2A271JN000 offers 0.197" lead spacing. Combined inventory totals 2567 pcs.

Frequently Asked Questions (FAQ)

Q: Can SR151A271JAR replace SR071A271JART directly on the PCB?

A: Electrical substitution is complete. The primary difference is seated height: SR151A271JAR measures 0.150" versus SR071A271JART at 0.100". Verify PCB clearance above the component. Lead style differs (straight vs. kinked), which may affect insertion force and board assembly compatibility. Confirm with your PCB layout and assembly process specifications.

Q: What is the significance of lead spacing differences between substitute parts?

A: Lead spacing determines PCB hole pattern compatibility. SR071A271JART and SR151A271JAR both use 0.100" (2.54mm) spacing, matching the original footprint. RDE5C2A271J0K1H03B and FK28C0G2A271JN000 require 0.197" (5.00mm) spacing. RDE5C2A271J0S1H03A and FK18C0G2A271JN020 use 0.098" (2.50mm) spacing. Lead spacing must match your PCB design; mismatched spacing prevents proper component insertion.

Q: Why do TDK FK series parts show "Not For New Designs" status?

A: This designation indicates the product line is in end-of-life phase. Manufacturers apply this status when transitioning to newer product families or discontinuing legacy lines. These parts remain available for existing inventory but are not recommended for new product development. Use only when active alternatives are unavailable or for legacy system support.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the original SR071A271JART specifications. Compliance certifications are identical across all qualified substitutes.

Q: Does packaging format (Bulk vs. Cut Tape) affect electrical performance?

A: No. Packaging format affects only supply chain logistics and assembly automation compatibility. RDE5C2A271J0S1H03A is supplied in Cut Tape (CT) format; all other parts are supplied in Bulk. Electrical and mechanical specifications remain identical regardless of packaging format.

Q: Which substitute offers the best supply continuity?

A: RDE5C2A271J0S1H03A (Murata) provides the highest inventory (3036 pcs) with active product status. SR151A271JAR (KYOCERA AVX) offers 2300 pcs with active status and manufacturer recommendation. Both ensure reliable long-term availability for production requirements.
