Parameter Comparison

Engineering Selection Recommendations

Both the SSQ-108-21-G-S and SSQ-108-01-G-S are active production parts manufactured by Samtec Inc. with identical electrical and mechanical specifications. Both parts are ROHS3 compliant and carry UL94 V-0 flammability certification, meeting regulatory requirements for industrial and commercial applications. Selection between these parts may be based on inventory availability, lead time, or supply chain considerations, as all functional parameters are equivalent.

Frequently Asked Questions (FAQ)

Q: Can SSQ-108-01-G-S be used as a direct replacement for SSQ-108-21-G-S?

A: Yes. Both parts share identical specifications across all critical parameters including connector type, position count, pitch, contact finish, voltage rating, operating temperature range, and flammability rating. Direct substitution is supported without design modification.

Q: Are there any mechanical compatibility differences between these parts?

A: No. Both parts feature identical through-hole mounting, solder termination, push-pull fastening, insulation height, and contact geometry. PCB layout and assembly procedures remain unchanged.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SSQ-108-21-G-S and SSQ-108-01-G-S are ROHS3 compliant, carry UL94 V-0 flammability certification, and share the same ECCN and HTSUS classifications.

Q: What is the difference between these part numbers if all specifications are identical?

A: The difference lies in the suffix designation within the SSQ-108 base product family. Both parts are functionally equivalent 8-position receptacle connectors within the same series, with the suffix indicating internal manufacturing or packaging variants that do not affect electrical or mechanical performance.

Q: Are both parts currently in production?

A: Yes. Both SSQ-108-21-G-S and SSQ-108-01-G-S maintain active product status with current inventory availability.
