Choosing a compression spring is less about picking a general-purpose part and more about matching the stated wire size, diameter, length, material, and quantity to the job at hand. Here, the choice is clear: one option centers on a broad 304 stainless-steel dimensional selection at a 305mm length, while the other is a galvanized-steel 0.8mm-wire format offered in a 100-piece pack.
Quick verdict
Pick the Compression Spring 0.3 - 5mm & 305mm Length Pressure Small 304 Stainless Steels when a longer listed length, a wider dimensional menu, and 304 stainless steel are the important requirements. Pick the 0.8mm Wire Compression Spring 7-11mm Diameter & 10-100mm Length Pressure Small when the stated 100-piece pack is more useful and its narrower 0.8mm-wire format aligns with the required dimensions.
The listed-price gap is $176.60, so this is a meaningful choice between a broader stainless-steel spring selection and a multi-piece galvanized-steel format rather than two like-for-like parts.
Listed-price comparison

Where each spring wins
304 Stainless Compression Spring, 305mm
This is the stronger match for a dimensional requirement that calls for its stated 305mm length. Its selection covers wire diameters from 0.3mm to 5mm and outer diameters from 3mm to 60mm, giving it substantially broader stated dimensions than the 0.8mm-wire alternative. Its open ends are also specified.
0.8mm Wire Compression Spring, 100 pack
This is the practical pick when the quantity itself matters: it is listed as a pack of 100. The title also focuses the selection on 0.8mm wire with a 7-11mm diameter range and a 10-100mm length range, which gives a more focused starting point for smaller-format requirements.
Product notes
Compression Spring 0.3 - 5mm & 305mm Length Pressure Small 304 Stainless Steels
The main reason to choose this spring is the combination of stated 304 stainless-steel material and a wide set of size choices. The listing identifies wire diameters from 0.3mm through 5mm, outer diameters from 3mm through 60mm, and a 305mm spring length, making it the more adaptable choice when the needed dimensions have not been narrowed to a single 0.8mm-wire format. It is also identified with open ends. The limitation is straightforward: at USD 250.78, it is the higher listed-price option, sitting $176.60 above the other spring. This choice makes sense when the 304 stainless-steel requirement and its broader dimensional scope outweigh the higher listed figure.
0.8mm Wire Compression Spring 7-11mm Diameter & 10-100mm Length Pressure Small
This spring is the clearer choice for a requirement built around the title's 0.8mm wire, 7-11mm diameter range, and 10-100mm length range. Its listed galvanized-steel finish and 100-piece pack set it apart as a group-quantity format rather than a single long 305mm spring selection. The concrete advantage is that the pack count can suit projects calling for repeated pieces in the same general size family. Its limitation is material-specific: it is listed as steel with a galvanized finish rather than 304 stainless steel. Choose it when the narrower stated dimensions and 100-piece count are the priority, rather than the 304 stainless-steel construction of the other option.
Final choice by use case
Choose the 304 Stainless Compression Spring when 304 stainless steel is a required part of the specification and a wide range of dimensional choices is useful. Choose the 0.8mm Wire Compression Spring when a 100-piece pack is the key deciding factor and the smaller stated wire, diameter, and length ranges are the intended format.
