Frequently Asked Questions (FAQ)

Q: Can SR151C152KAR replace SR155C152MAATR2 in all applications?

A: The SR151C152KAR is a direct mechanical and electrical substitute for circuits operating at or below 50V. The higher 100V rating and improved ±10% tolerance provide additional design margin. Substitution is valid when circuit voltage requirements do not exceed 100V and the improved tolerance does not conflict with design specifications.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical radial through-hole package dimensions of 0.150" L x 0.100" W (3.81mm x 2.54mm) with 0.100" (2.54mm) lead spacing, enabling direct PCB footprint compatibility without layout modification.

Q: What is the significance of the tolerance difference?

A: The SR155C152MAATR2 specifies ±20% tolerance, while SR151C152KAR specifies ±10%. The tighter tolerance of the substitute part reduces capacitance variation across the production range, beneficial for precision-dependent circuit designs. Both tolerances remain within acceptable ranges for general-purpose applications.

Q: Do both parts operate across the same temperature range?

A: Yes. Both parts are rated for -55°C to 125°C operation with identical X7R temperature coefficient characteristics, ensuring equivalent frequency stability and thermal performance across the full operating range.

Q: Are there compliance or regulatory differences between these parts?

A: No. Both parts maintain identical ROHS3 compliance and REACH unaffected status, ensuring equivalent regulatory acceptance and environmental compliance across substitution.
