SR141C102KART Equivalent & Substitute Parts

Part Overview

The SR141C102KART is a 1000 pF ±10% 100V ceramic capacitor 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 in active production status. Substitute parts are necessary when the original part becomes unavailable, when specific packaging formats are required for manufacturing processes, or when alternative lead configurations better suit board layout constraints.

Substitute Part Grouping Explanation

Substitution eligibility for the SR141C102KART is determined by strict electrical and mechanical compatibility criteria. All substitute parts must maintain identical electrical specifications: 1000 pF capacitance, ±10% tolerance, 100V rated voltage, and X7R temperature coefficient with -55°C to 125°C operating range. All candidates must be through-hole radial ceramic capacitors with ROHS3 compliance.

Mechanical compatibility is evaluated based on lead spacing and physical dimensions. The SR141C102KART features 0.100" (2.54mm) lead spacing with formed kinked leads and dimensions of 0.200" L x 0.100" W (5.08mm x 2.54mm). Substitute parts are grouped into two categories:

Category A - Direct Mechanical Substitutes (0.100" Lead Spacing): Parts with identical 0.100" lead spacing that can be used as direct board-level replacements without PCB modification.

Category B - Functional Equivalents (0.200" Lead Spacing): Parts with 0.200" (5.08mm) lead spacing that provide electrical equivalence but require PCB layout adjustment due to different lead spacing.

Category C - Cross-Manufacturer Equivalents: Parts from alternative manufacturers (KEMET, TDK, Vishay) that meet all electrical specifications and offer packaging or availability advantages.

Engineering Selection Recommendations

KYOCERA AVX SR151 Series (0.100" Lead Spacing): The SR151C102KAATR1, SR151C102KAR, and SR151C102KARTR1 are direct electrical and mechanical substitutes for the SR141C102KART. All maintain identical electrical specifications and 0.100" lead spacing. These parts offer higher inventory availability and are available in both bulk and cut tape packaging formats. All are active production parts with ROHS3 compliance.

KYOCERA AVX SR211 Series (0.200" Lead Spacing): The SR211C102KAA, SR211C102KAR, and SR211C102KARTR1 provide electrical equivalence with identical capacitance, voltage, tolerance, and temperature coefficient. However, the 0.200" lead spacing differs from the original part and requires PCB layout modification. These parts are manufacturer-recommended alternatives and offer the highest inventory availability, particularly SR211C102KARTR1 with 20,428 pieces in stock.

KEMET C315C102K1R5TA: This KEMET GoldMax 300 Comm X7R part meets all electrical specifications and features 0.100" lead spacing compatible with the original design. With 28,525 pieces in inventory, this cross-manufacturer option provides excellent availability and is an active production part.

Vishay Beyschlag Mono-Kap™ K Series: The K102K15X7RH53L2 and K102K15X7RH5TK2 are functionally equivalent with 0.098" lead spacing, which is mechanically similar to 0.100" spacing for most applications. Both are active production parts with strong inventory levels. The K102K15X7RH5TK2 offers the highest availability at 20,691 pieces in cut tape format.

TDK FK18X7R2A102KN020: This part meets all electrical specifications but carries "Not For New Designs" status and should be used only for legacy system maintenance or repair applications.

Frequently Asked Questions (FAQ)

Q: Can I use SR151C102KAATR1 as a direct replacement for SR141C102KART?

A: Yes. Both parts share identical electrical specifications (1000 pF, ±10%, 100V, X7R) and 0.100" lead spacing. The primary difference is physical size: SR151 is more compact (0.150" L vs 0.200" L) with straight leads instead of formed kinked leads. This makes it suitable for direct PCB substitution without layout modification.

Q: What is the difference between bulk and cut tape packaging?

A: Bulk packaging contains loose components suitable for manual assembly or small-scale production. Cut tape (CT) and tape & reel (TR) packaging are designed for automated pick-and-place assembly equipment. Selection depends on manufacturing process requirements.

Q: Can I use SR211C102KARTR1 instead of SR141C102KART?

A: Electrically yes, but mechanically it requires PCB modification. The SR211 series has 0.200" lead spacing compared to the original 0.100" spacing. This part is suitable only if your PCB layout can accommodate the wider lead spacing or if you can modify the board design.

Q: Why is FK18X7R2A102KN020 marked "Not For New Designs"?

A: This TDK part is in legacy status, indicating the manufacturer is phasing it out. It should be used only for repair or maintenance of existing systems. For new designs, select from active production alternatives.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the original SR141C102KART specification.

Q: What is the difference between formed kinked leads and straight leads?

A: Formed kinked leads are pre-bent for specific PCB hole spacing and provide mechanical retention during insertion. Straight leads require manual bending or are used in applications where lead forming is performed during assembly. Both styles are functionally equivalent once soldered.

Q: Can I use the Vishay K102K15X7RH5TK2 with 0.098" lead spacing on a board designed for 0.100" spacing?

A: The 0.098" spacing is mechanically similar to 0.100" and may work in many applications, but this is a marginal fit. Verify with your PCB design and assembly process before committing to production use.
