SR075A331JAT - 330 pF 50V C0G/NP0 Radial Ceramic Capacitor Equivalent & Substitute Parts

Part Overview

The SR075A331JAT is a 330 pF ceramic capacitor manufactured by KYOCERA AVX in the SkyCap® SR series. This through-hole radial component operates at 50V with C0G/NP0 temperature coefficient stability across -55°C to 125°C. The part is currently active in production with 940 units in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when lead spacing and physical dimensions must accommodate specific PCB layouts.

Substitute Part Grouping Explanation

Substitution eligibility for the SR075A331JAT is determined by the following criteria:

Electrical Parameters: Capacitance value (330 pF), tolerance (±5%), voltage rating (50V), and temperature coefficient (C0G/NP0) must be identical
Mechanical Compatibility: Mounting type (through-hole radial) and lead style must support PCB assembly without modification
Environmental Compliance: RoHS3 compliance and REACH status must match or exceed the original specification
Physical Constraints: Lead spacing and overall dimensions must be compatible with the target PCB layout

All substitute parts listed below meet these core electrical and mechanical requirements while accommodating variations in physical dimensions and packaging formats.

Engineering Selection Recommendations

Primary Substitutes (Active Product Status)

K331J15C0GF5TL2 and K331J15C0GF53L2 from Vishay Beyschlag/Draloric/BC Components are active production parts with the highest inventory availability (21021 and 2337 units respectively). Both maintain identical electrical specifications and RoHS3 compliance. K331J15C0GF5TL2 offers 0.098" lead spacing matching the original SR075A331JAT, while K331J15C0GF53L2 provides the same spacing with bulk packaging.

RDE5C1H series parts from Murata Electronics (RDE5C1H331J0K1H03B, RDE5C1H331J0M1H03A, RDE5C1H331J0P1H03B) are all active production components with full RoHS3 compliance. RDE5C1H331J0P1H03B matches the 0.098" lead spacing of the original part. The RDE5C1H series accommodates 0.197" lead spacing variants for applications requiring wider spacing.

Secondary Substitutes (Not For New Designs)

FK18C0G1H331JN020 and FK28C0G1H331JN000 from TDK Corporation are marked "Not For New Designs" and should be used only for legacy system maintenance or repair applications. Both maintain full electrical and compliance specifications but are being phased out of production.

Lead Spacing Considerations

The original SR075A331JAT specifies 0.100" (2.54mm) lead spacing. Direct mechanical substitutes with matching 0.098" (2.50mm) spacing include K331J15C0GF5TL2, K331J15C0GF53L2, and RDE5C1H331J0P1H03B. Applications requiring 0.197" (5.00mm) spacing can use K331J15C0GF5TH5, FK28C0G1H331JN000, RDE5C1H331J0K1H03B, or RDE5C1H331J0M1H03A.

Frequently Asked Questions (FAQ)

Q: Can I substitute the SR075A331JAT with any of these parts without PCB modification?

A: Substitutes with 0.098" lead spacing (K331J15C0GF5TL2, K331J15C0GF53L2, RDE5C1H331J0P1H03B) are mechanically compatible with minimal spacing variation from the original 0.100" specification. Parts with 0.197" spacing require PCB pad repositioning and are not direct drop-in replacements.

Q: What is the difference between Cut Tape (CT) and Bulk packaging?

A: Cut Tape packaging is supplied on continuous tape and cut to order, suitable for automated pick-and-place assembly. Bulk packaging is supplied loose or in trays, typically for manual assembly or lower-volume applications. Electrical performance is identical between packaging formats.

Q: Why are some substitutes marked "Not For New Designs"?

A: Parts marked "Not For New Designs" (FK18C0G1H331JN020, FK28C0G1H331JN000) are in end-of-life status and may have limited future availability. These parts are suitable for maintaining existing products but should not be selected for new circuit designs.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH Unaffected status, matching the environmental compliance of the original SR075A331JAT.

Q: What is the significance of C0G/NP0 temperature coefficient?

A: C0G and NP0 designations indicate zero temperature coefficient ceramic capacitors with stable capacitance across the -55°C to 125°C operating range. All substitute parts maintain this specification, ensuring equivalent performance in temperature-sensitive applications.
