Substitute Part Grouping Explanation

Substitution eligibility for the SSQ-150-21-G-S is determined by the following critical parameters:

  • Connector Type & Position Count: Must be receptacle configuration with 50 positions
  • Pitch Specification: Must maintain 0.100" (2.54mm) mating pitch
  • Contact Finish: Must feature gold-plated mating contacts
  • Mounting Configuration: Must support through-hole solder termination
  • Electrical Ratings: Must meet or exceed 465VAC / 655VDC voltage specifications
  • Temperature Range: Must support -55°C to 125°C operating range
  • Compliance: Must maintain ROHS3 compliance and UL94 V-0 flammability rating

The SSQ-150-01-G-S qualifies as a direct substitute based on identical specifications across all critical parameters within the SSQ series.

Engineering Selection Recommendations

Both SSQ-150-21-G-S and SSQ-150-01-G-S are active production parts with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on:

  • Inventory Availability: SSQ-150-01-G-S maintains higher stock levels (1017 units) compared to SSQ-150-21-G-S (682 units)
  • Supply Chain Requirements: Both parts share identical electrical, mechanical, and thermal specifications
  • Application Compatibility: No functional differences exist between the two part numbers within the SSQ-150 base product family

Frequently Asked Questions (FAQ)

Q: Can SSQ-150-01-G-S be used as a direct replacement for SSQ-150-21-G-S?

A: Yes. Both parts are 50-position receptacle connectors with identical mating pitch (0.100"), contact finish (gold), voltage rating (465VAC / 655VDC), operating temperature range (-55°C to 125°C), and compliance certifications (ROHS3, UL94 V-0). No design modifications are required.

Q: What is the difference between SSQ-150-21-G-S and SSQ-150-01-G-S?

A: The parts are functionally equivalent. The difference in part number suffix (-21-G-S versus -01-G-S) reflects internal Samtec manufacturing or distribution variants within the SSQ-150 base product line. All electrical and mechanical parameters are identical.

Q: Are there any PCB layout considerations when substituting these connectors?

A: No. Both connectors share identical through-hole mounting specifications, insulation height (0.335"), and contact post dimensions (0.104"). PCB footprints and assembly procedures remain unchanged.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SSQ-150-21-G-S and SSQ-150-01-G-S are ROHS3 compliant and carry UL94 V-0 flammability certification. ECCN and HTSUS classifications are identical.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection may be influenced by current inventory levels, supplier availability, or existing supply agreements. Both parts maintain active production status.
