SR151C103MAATR2 Equivalent & Substitute Parts

Part Overview

The SR151C103MAATR2 is a 10000 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 the operating temperature range of -55°C to 125°C. The part is ROHS3 compliant and currently in active production status. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part number becomes unavailable or when alternative packaging or tolerance specifications are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SR151C103MAATR2 is determined by strict equivalence in the following parameters: capacitance value (10000 pF), voltage rating (100V), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), mounting type (through hole), package configuration (radial), and lead spacing (0.100"). All substitute parts maintain these core electrical and mechanical specifications.

Tolerance variations are permitted as substitute criteria. The main part specifies ±20% tolerance. Substitute parts with tighter tolerances (±10% or ±5%) are electrically compatible and represent upgrades in precision. Packaging format differences (bulk, cut tape) do not affect electrical performance and are acceptable for substitution based on procurement requirements.

All identified substitutes are manufactured by KYOCERA AVX within the SkyCap® SR series, maintain active product status, and comply with ROHS3 and REACH requirements.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain electrical equivalence to the SR151C103MAATR2 through identical capacitance, voltage rating, temperature coefficient, and operating temperature specifications. Selection among substitutes should be based on packaging requirements and tolerance precision needs.

For applications requiring the original tape and reel packaging format, the SR151C103MAATR2 remains the specified part. When tape and reel packaging is not required, SR151C103KAATR1 and SR151C103KARTR1 offer cut tape alternatives with ±10% tolerance and higher inventory availability (8095 and 3195 units respectively).

For bulk packaging requirements, SR151C103KAR (±10% tolerance, 2000 units) and SR151C103JAR (±5% tolerance, 1488 units) are available. The SR151C103JAR provides the tightest tolerance specification at ±5%, suitable for applications with stricter capacitance accuracy requirements.

All parts maintain ROHS3 compliance and active product status, ensuring long-term availability and regulatory conformance.

Frequently Asked Questions (FAQ)

Q: Can SR151C103JAR replace SR151C103MAATR2 in my circuit?

A: Yes. Both parts have identical capacitance (10000 pF), voltage rating (100V), and temperature coefficient (X7R). The SR151C103JAR has a tighter tolerance specification (±5% versus ±20%), which represents improved precision. The primary difference is packaging format (bulk versus tape and reel).

Q: What is the difference between ±20%, ±10%, and ±5% tolerance?

A: Tolerance specifies the allowable deviation from the nominal 10000 pF capacitance value. ±20% allows deviation from 8000 pF to 12000 pF. ±10% allows 9000 pF to 11000 pF. ±5% allows 9500 pF to 10500 pF. Tighter tolerances provide more precise capacitance values for applications requiring strict circuit performance.

Q: Does packaging format affect electrical performance?

A: No. Tape and reel, cut tape, and bulk packaging formats do not affect the electrical characteristics of the capacitor. Packaging selection is based on assembly equipment compatibility and procurement workflow requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts, including SR151C103MAATR2, SR151C103JAR, SR151C103KAATR1, SR151C103KAR, and SR151C103KARTR1, are ROHS3 compliant and REACH unaffected.

Q: Which substitute part has the highest inventory availability?

A: SR151C103KAATR1 has the highest inventory with 8095 units in stock. This part is available in cut tape packaging with ±10% tolerance.
