Substitute Part Grouping Explanation

Substitute parts for the SR151C102MAATR2 are qualified based on the following criteria:

Electrical Compatibility: All substitute parts maintain the same capacitance value (1000 pF), voltage rating (100V), and temperature coefficient (X7R). Tolerance variations are permitted within the scope of general-purpose applications, as the main part specifies ±20% tolerance.

Mechanical Compatibility: All substitute parts are radial through-hole packages with compatible lead spacing and physical dimensions suitable for PCB mounting in the same footprint category.

Regulatory Compliance: All substitute parts maintain ROHS3 compliance and active product status, ensuring availability and regulatory alignment.

Packaging Considerations: Substitute parts may differ in packaging format (Cut Tape, Bulk, Tape & Reel) based on procurement requirements, but electrical and mechanical specifications remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

KYOCERA AVX SR151C102KAATR1 and SR151C102KAR: These parts are direct upgrades from the main part, 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: SR151C102KAATR1 is supplied in Cut Tape format, while SR151C102KAR is supplied in Bulk format.

Vishay Beyschlag K102K15X7RH5TK2: This part provides equivalent electrical performance with ±10% tolerance and is supplied in Tape & Reel packaging. Lead spacing is 0.098" (2.50mm), which represents a minor dimensional variation from the main part's 0.100" (2.54mm) spacing. This part is suitable for applications where the slight lead spacing difference does not impact PCB layout constraints. All parts maintain ROHS3 compliance and active product status.

Frequently Asked Questions (FAQ)

Q: Can SR151C102KAATR1 and SR151C102KAR be used interchangeably with SR151C102MAATR2?

A: Yes. Both parts maintain identical capacitance (1000 pF), voltage rating (100V), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), and lead spacing (0.100" / 2.54mm). The primary difference is tolerance: the substitutes offer ±10% versus the main part's ±20%, which represents improved performance. Packaging format differs (Cut Tape versus Bulk) but does not affect electrical or mechanical compatibility.

Q: Is the K102K15X7RH5TK2 a suitable substitute despite the lead spacing difference?

A: The K102K15X7RH5TK2 has lead spacing of 0.098" (2.50mm) compared to the main part's 0.100" (2.54mm). This 0.002" (0.04mm) difference is within typical PCB manufacturing tolerances for through-hole applications. Compatibility depends on specific PCB layout constraints. All other electrical and mechanical parameters are equivalent.

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

A: Cut Tape (CT) packaging supplies components on continuous tape cut into specific lengths, suitable for automated assembly processes. Bulk packaging supplies loose components, typically for manual assembly or lower-volume applications. Electrical and mechanical specifications remain identical regardless of packaging format.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, ensuring regulatory alignment with the main part SR151C102MAATR2.

Q: Can tolerance differences affect circuit performance?

A: Tolerance differences between ±20% and ±10% may impact circuit performance in applications with tight capacitance requirements. The ±10% tolerance parts (SR151C102KAATR1, SR151C102KAR, K102K15X7RH5TK2) provide improved precision compared to the main part's ±20% tolerance.
