Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following critical parameters: capacitance value (1000 pF), tolerance (±10%), voltage rating (50V minimum), temperature coefficient (X7R), operating temperature range (-55°C ~ 125°C), mounting type (through hole), and package configuration (radial). Physical dimensions and lead spacing must accommodate PCB layout requirements. All substitute parts must maintain ROHS3 compliance and active or equivalent product status.

Substitute parts are grouped into the following categories:

Parametric Equivalents (Same Voltage Rating - 50V): Parts with identical electrical specifications and 50V voltage rating, differing only in packaging format or lead configuration.

Voltage Upgrades (100V Rating): Parts with elevated voltage ratings that provide enhanced safety margin while maintaining all other electrical parameters. These are suitable for applications where higher voltage headroom is beneficial.

Alternative Manufacturers: Parts from KEMET, TDK Corporation, and Vishay Beyschlag that meet identical electrical specifications and mechanical compatibility requirements.

Frequently Asked Questions (FAQ)

Q: Can SR155C102KARTR1 directly replace SR155C102KAATR2?

A: Yes. Both parts share identical electrical specifications (1000 pF, ±10%, 50V, X7R) and mechanical compatibility (0.150" L x 0.100" W, 0.100" lead spacing, straight leads). The difference is packaging format: SR155C102KAATR2 is Tape & Reel (TR) while SR155C102KARTR1 is Cut Tape (CT). Electrical performance and PCB mounting are equivalent.

Q: What is the advantage of using SR151C102KARTR1 instead of SR155C102KAATR2?

A: SR151C102KARTR1 provides 100V voltage rating compared to 50V in the main part. This upgrade offers increased safety margin in applications subject to voltage transients or where design specifications require higher voltage headroom. All other electrical parameters remain identical. Physical dimensions and lead spacing are compatible.

Q: Can SR075C102KARTR1 be used in place of SR155C102KAATR2?

A: Yes, with lead configuration consideration. SR075C102KARTR1 provides identical electrical specifications and dimensions but features kinked (formed) leads instead of straight leads. PCB hole pattern and assembly process compatibility must be verified. Both parts are ROHS3 compliant and active products.

Q: Are KEMET C315C102K5R5TA and KYOCERA AVX SR155C102KAATR2 interchangeable?

A: Yes, for electrical and mechanical compatibility. Both provide 1000 pF, ±10%, 50V, X7R specifications with identical dimensions (0.150" L x 0.100" W) and lead spacing (0.100"). Differences exist in packaging format (KEMET is Bulk; KYOCERA AVX is Tape & Reel) and manufacturer series designation. Both are ROHS3 compliant and active products.

Q: Why is FK18X7R1H102KN020 marked "Not For New Designs"?

A: FK18X7R1H102KN020 carries "Not For New Designs" status from TDK Corporation, indicating the product line is in end-of-life phase. This part is suitable only for legacy design support, repair, or inventory management. New designs should utilize active product alternatives such as SR155C102KARTR1, C315C102K5R5TA, or other active-status equivalents.

Q: What is the difference between SR215C102KAATR1 and SR155C102KAATR2?

A: Both parts provide identical electrical specifications (1000 pF, ±10%, 50V, X7R). SR215C102KAATR1 features larger physical dimensions (0.200" L x 0.125" W) with 0.200" lead spacing, compared to SR155C102KAATR2 (0.150" L x 0.100" W with 0.100" lead spacing). SR215C102KAATR1 is suitable for PCB layouts requiring increased component spacing or where larger footprint is acceptable.

Q: Can K102K15X7RH5TK2 from Vishay be used as a direct replacement?

A: K102K15X7RH5TK2 provides electrical equivalence at 100V rating with active product status. Physical dimensions (0.157" L x 0.102" W) and lead spacing (0.098") differ from the main part. PCB layout verification is required to confirm hole pattern compatibility and assembly process suitability before implementation.
