Substitute Part Grouping Explanation

The SMP18FS-REEL has one direct equivalent substitute: SMP18FSZ-REEL. This substitution is valid based on the following matching parameters:

Both parts share the identical base product number (SMP18), functional classification (Sample and Hold IC for Data Acquisition), and physical package specification (16-SOIC with 0.154" / 3.90mm width). The mounting type (Surface Mount), electrical category (Linear, Amplifiers), and regulatory classifications (ECCN: EAR99, HTSUS: 8542.33.0001) are identical across both parts. Moisture sensitivity level (MSL 1 - Unlimited) is equivalent, confirming compatibility in handling and storage requirements.

The primary distinction is product status: SMP18FS-REEL is obsolete, while SMP18FSZ-REEL is active production. The substitute part is available in Tape & Reel packaging format, providing standard surface mount component delivery.

Parameter Comparison

Engineering Selection Recommendations

The SMP18FSZ-REEL is the direct functional equivalent for the obsolete SMP18FS-REEL. Selection of the substitute part is based on the following engineering criteria:
