SA305C104JAR Equivalent & Substitute Parts

Part Overview

The SA305C104JAR is a 0.1 µF ceramic capacitor rated at 50V with X7R temperature coefficient, manufactured by KYOCERA AVX in the SpinGuard® SA series. This through-hole axial component is designed for general-purpose applications and maintains active product status. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory constraints require component alternatives that meet identical electrical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the SA305C104JAR is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.1 µF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage rating: 50V (exact match required)
• Temperature coefficient: X7R (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)
• Mounting type: Through Hole (exact match required)
• Package type: Axial (exact match required)
• Lead style: Straight (exact match required)

The substitute part C412C104J5R5TA meets all electrical and mechanical criteria for direct substitution. Physical dimensions differ (0.120" Dia x 0.170" L versus 0.150" Dia x 0.290" L), which may affect board layout and mechanical fit but does not impact electrical performance or functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the SA305C104JAR and C412C104J5R5TA are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution. Selection between these parts should be based on:

• Inventory availability and lead time requirements
• Physical space constraints on the printed circuit board, as the KEMET part is smaller
• Packaging format preference (SA305C104JAR supplied in Tape & Reel; C412C104J5R5TA supplied in Bulk)
• Supplier relationship and procurement logistics

Both components satisfy identical electrical specifications and operating conditions.

Frequently Asked Questions (FAQ)

Q: Can C412C104J5R5TA replace SA305C104JAR in all applications?

A: Yes, from an electrical standpoint. Both parts have identical capacitance, voltage rating, tolerance, temperature coefficient, and operating temperature range. Physical dimensions differ, so board layout and mechanical fit must be verified before implementation.

Q: What is the significance of the X7R temperature coefficient?

A: X7R indicates the capacitance change over temperature is ±15% across the -55°C to 125°C operating range. This specification ensures stable performance across the full temperature envelope for both parts.

Q: Are there packaging considerations when substituting these parts?

A: Yes. The SA305C104JAR is supplied in Tape & Reel format, while C412C104J5R5TA is supplied in Bulk. Additionally, the KEMET part is physically smaller (0.120" Dia x 0.170" L versus 0.150" Dia x 0.290" L), which may affect board layout and lead spacing on existing designs.

Q: Do both parts meet current compliance standards?

A: Yes. Both SA305C104JAR and C412C104J5R5TA are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What parameters must match exactly for substitution?

A: Capacitance (0.1 µF), tolerance (±5%), voltage rating (50V), temperature coefficient (X7R), operating temperature range (-55°C ~ 125°C), mounting type (Through Hole), package type (Axial), and lead style (Straight) must all match exactly for direct electrical substitution.
