SR155C102MAATR2 Equivalent & Substitute Parts

Part Overview

The SR155C102MAATR2 is a 1000 pF ceramic capacitor rated at 50V with X7R temperature coefficient, manufactured by KYOCERA AVX under the SkyCap® SR series. This through-hole radial component is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is ROHS3 compliant and currently in active production status with 1135 units in stock.

Equivalent and substitute parts are identified when design requirements allow for variations in tolerance, voltage rating, packaging format, or lead configuration while maintaining the core electrical functionality of 1000 pF capacitance and X7R temperature stability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SR155C102MAATR2 is determined by the following criteria:

Electrical Parameters (Must Match or Exceed):

• Capacitance: 1000 pF (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Voltage Rating: 50V minimum (equal or higher acceptable)
• Operating Temperature Range: -55°C to 125°C (exact match required)

Mechanical Parameters (Must Be Compatible):

• Mounting Type: Through Hole (required)
• Package / Case: Radial (required)
• Lead Spacing: 0.100" (2.54mm) (exact match required)

Tolerance Consideration:

• Original part tolerance: ±20%
• Substitute parts with ±10% tolerance are acceptable as they represent improved precision within the same application space

Packaging Format:

• Cut Tape (CT), Bulk, and Tape & Reel (TR) formats are interchangeable for the same electrical component

Substitute parts are grouped by voltage rating (50V or 100V) and tolerance level (±20% or ±10%), with all candidates meeting the mechanical and thermal requirements of the original specification.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Tolerance & Voltage):

• SR155C102KARTR1: KYOCERA AVX equivalent with improved ±10% tolerance at 50V rating. Identical mechanical footprint and lead configuration. Active product status with 3373 units available.
• C320C102M5R5TA: KEMET alternative maintaining ±20% tolerance and 50V rating. Maintains X7R stability and through-hole radial package. ROHS3 compliant with 12699 units in stock.

Upgraded Tolerance (±10% vs ±20%):

• SR075C102KARTR1: KYOCERA AVX part with tighter ±10% tolerance at 50V. Features formed kinked leads instead of straight leads. Highest inventory availability at 4176 units.

Higher Voltage Rating (100V vs 50V):

• SR151C102KAATR1 and SR151C102KAR: KYOCERA AVX options with 100V rating and ±10% tolerance. Suitable for applications requiring voltage margin. Both active products with 4361 and 3280 units respectively.
• K102K15X7RH5TK2: Vishay Beyschlag alternative with 100V rating and ±10% tolerance. Largest inventory at 20691 units. Features formed kinked leads and slightly different physical dimensions (0.157" L x 0.102" W vs 0.150" L x 0.100" W).

All substitute candidates are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes, matching the compliance profile of the original part.

Frequently Asked Questions (FAQ)

Q: Can I use SR155C102KARTR1 as a direct replacement for SR155C102MAATR2? A: Yes. Both parts share identical electrical specifications (1000 pF, 50V, X7R), mechanical footprint (0.150" L x 0.100" W, 2.54mm lead spacing), and lead configuration (straight). The primary difference is improved tolerance (±10% vs ±20%), which represents a functional upgrade with no compatibility concerns.

Q: What is the difference between SR075C102KARTR1 and SR155C102KARTR1? A: Both are 1000 pF, 50V, X7R capacitors with ±10% tolerance from KYOCERA AVX. The SR075 features formed kinked leads, while the SR155 has straight leads. The SR075 has a lower seated height (0.100" vs 0.150"). Lead style selection depends on PCB design and assembly equipment compatibility.

Q: Can I substitute a 100V rated part (SR151C102KAATR1) for the 50V original? A: Yes, from an electrical standpoint. The 100V rating provides additional voltage margin and is mechanically compatible. However, this substitution should only be made if the application design permits the use of a higher voltage component. The 100V part maintains identical capacitance (1000 pF) and X7R temperature stability.

Q: Why does K102K15X7RH5TK2 have different physical dimensions? A: K102K15X7RH5TK2 is manufactured by Vishay Beyschlag and has slightly larger dimensions (0.157" L x 0.102" W vs 0.150" L x 0.100" W) and greater seated height (0.295" vs 0.150"). While electrically equivalent, PCB layout verification is required before substitution to ensure clearance and spacing compatibility.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the environmental and regulatory status of the original SR155C102MAATR2.

Q: What packaging formats are available for these parts? A: Substitute parts are available in Cut Tape (CT), Bulk, and Tape & Reel (TR) formats. Selection depends on procurement volume and assembly process requirements. All formats contain identical electrical components.
