SA101C681KAB Equivalent & Substitute Parts

Part Overview

The SA101C681KAB is a 680 pF ceramic capacitor rated at 100V with X7R temperature coefficient, manufactured by KYOCERA AVX as part of the SpinGuard® SA series. This through-hole axial component is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is currently active in production with 1120 units in stock. Substitute parts may be required due to packaging availability, lead time constraints, or specific procurement requirements for alternative packaging formats.

Substitute Part Grouping Explanation

Substitution for the SA101C681KAB is based on electrical and mechanical parameter equivalence. The primary substitute SA101C681KAR maintains identical electrical specifications: 680 pF capacitance, ±10% tolerance, 100V rating, and X7R temperature coefficient. Both parts share the same physical dimensions (0.100" Dia x 0.170" L), lead style (straight), and mounting configuration (through-hole axial). The key differentiator is packaging format: SA101C681KAB is supplied in standard packaging, while SA101C681KAR is supplied in Tape & Reel (TR) format. This distinction affects procurement and assembly processes but does not alter electrical or mechanical compatibility in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

Both SA101C681KAB and SA101C681KAR are electrically and mechanically equivalent for circuit applications. Selection between these parts should be based on procurement and assembly requirements:

The SA101C681KAB is suitable for applications requiring standard packaging with manual or low-volume assembly processes. The SA101C681KAR, supplied in Tape & Reel format, is optimized for automated assembly lines and high-volume production environments.

Compliance considerations: SA101C681KAR carries ROHS3 compliance certification, while SA101C681KAB is RoHS non-compliant. Applications subject to RoHS regulatory requirements should specify SA101C681KAR. Both parts maintain REACH Unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Are SA101C681KAB and SA101C681KAR electrically interchangeable?

A: Yes. Both parts have identical electrical specifications: 680 pF capacitance, ±10% tolerance, 100V rating, and X7R temperature coefficient. They operate identically across the -55°C to 125°C temperature range.

Q: What is the difference between these two part numbers?

A: The primary difference is packaging format. SA101C681KAB uses standard packaging, while SA101C681KAR is supplied in Tape & Reel (TR) format. Additionally, SA101C681KAR is ROHS3 compliant, whereas SA101C681KAB is RoHS non-compliant.

Q: Can I use SA101C681KAR in place of SA101C681KAB in my design?

A: Yes, provided your assembly process supports Tape & Reel packaging. The physical dimensions, lead configuration, and electrical performance are identical.

Q: Which part should I select for RoHS-regulated applications?

A: SA101C681KAR is ROHS3 compliant and is the appropriate choice for applications subject to RoHS directives.

Q: Are there any mechanical compatibility issues between these parts?

A: No. Both parts share identical dimensions (0.100" Dia x 0.170" L), straight lead style, and axial through-hole mounting configuration. They are mechanically interchangeable on PCBs designed for either part.
