SR151C102MAT Equivalent & Substitute Parts

Part Overview

The SR151C102MAT is a 1000 pF ceramic capacitor rated at 100V with X7R temperature coefficient, manufactured by KYOCERA AVX under the SkyCap® SR series. This radial through-hole component is designed for general-purpose applications requiring stable capacitance across a wide operating temperature range of -55°C to 125°C. The part is currently active in production and ROHS3 compliant.

Equivalent and substitute parts are identified when they maintain the same electrical specifications (capacitance, voltage rating, temperature coefficient) and mechanical compatibility (through-hole radial package, lead spacing, physical dimensions). Substitutes with improved tolerance ratings (±10% versus ±20%) are classified as upgrades while maintaining full functional equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Electrical Parameters (Must Match):

• Capacitance: 1000 pF
• Voltage Rating: 100V
• Temperature Coefficient: X7R
• Operating Temperature Range: -55°C to 125°C

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package Type: Radial
• Lead Spacing: 0.100" (2.54mm)

Tolerance Consideration: Parts with ±10% tolerance are direct upgrades to the ±20% specification, providing improved accuracy while maintaining full electrical and mechanical compatibility.

Packaging Format: Substitute parts may differ in packaging format (Bulk, Cut Tape) without affecting functional equivalence, as packaging relates to supply chain logistics rather than component performance.

Parameter Comparison

Engineering Selection Recommendations

SR151C102KAATR1 and SR151C102KAR (KYOCERA AVX): These parts are direct upgrades from the SR151C102MAT, offering improved tolerance (±10% versus ±20%) while maintaining identical electrical and mechanical specifications. Both are ROHS3 compliant and active in production. Selection between these two depends on packaging requirements: Cut Tape format for automated assembly processes or Bulk format for manual assembly or reel applications.

K102K15X7RH53L2 (Vishay Beyschlag/Draloric/BC Components): This part meets all electrical requirements and is ROHS3 compliant. Physical dimensions differ slightly (0.157" L x 0.102" W versus 0.150" L x 0.100" W for the main part, and height of 0.220" versus 0.150"), and lead spacing is 0.098" (2.50mm) versus 0.100" (2.54mm). These dimensional variations require verification of PCB layout compatibility before selection. The part is active in production with substantial inventory availability.

All substitute parts maintain the same operating temperature range (-55°C to 125°C) and are ROHS3 compliant, ensuring regulatory compliance across applications.

Frequently Asked Questions (FAQ)

Q: Can SR151C102KAATR1 and SR151C102KAR be used interchangeably with SR151C102MAT?

A: Yes. Both parts are electrically and mechanically equivalent to the SR151C102MAT. The primary differences are tolerance (±10% versus ±20%) and packaging format. The improved tolerance makes these parts suitable for applications requiring tighter capacitance control.

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

A: Cut Tape (CT) packaging is supplied on tape and reel, optimized for automated pick-and-place assembly. Bulk packaging is supplied loose or in trays, suitable for manual assembly or applications where reel compatibility is not required. Electrical performance is identical.

Q: Is K102K15X7RH53L2 a direct replacement for SR151C102MAT?

A: K102K15X7RH53L2 is electrically equivalent but has different physical dimensions and lead spacing. PCB layout compatibility must be verified before substitution. The component height (0.220" versus 0.150") and lead spacing (0.098" versus 0.100") may affect board routing and component clearance.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance profile of the SR151C102MAT.

Q: What determines whether a part can substitute for SR151C102MAT?

A: Substitution requires matching capacitance (1000 pF), voltage rating (100V), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), mounting type (through-hole), package type (radial), and lead spacing (0.100" / 2.54mm). Tolerance and packaging format do not prevent substitution.
