Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSQ-105-21-F-D is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Number of positions (10)
• Pitch spacing (0.100" / 2.54mm)
• Row configuration (2 rows with 0.100" spacing)
• Mounting method (Through Hole)
• Termination type (Solder)
• Fastening mechanism (Push-Pull)
• Contact finish specification (Gold mating surface)
• Operating temperature range (-55°C ~ 125°C)
• Voltage rating (465VAC, 655VDC minimum)
• Flammability compliance (UL94 V-0)

The SSQ-105-01-F-D qualifies as a direct substitute because it maintains identical specifications across all critical electrical and mechanical parameters within the SSQ series.

Parameter Comparison

Engineering Selection Recommendations

Both SSQ-105-21-F-D and SSQ-105-01-F-D are active production parts with ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on inventory availability and supply chain requirements. The SSQ-105-01-F-D currently maintains higher inventory (1034 units) compared to SSQ-105-21-F-D (1014 units), making it suitable for applications requiring immediate procurement. Both parts meet identical electrical and mechanical specifications and are interchangeable within the same circuit design.

Frequently Asked Questions (FAQ)

Q: Are SSQ-105-21-F-D and SSQ-105-01-F-D fully interchangeable?

A: Yes. Both parts maintain identical specifications across all critical parameters including connector type, position count, pitch spacing, row configuration, mounting method, termination type, fastening mechanism, contact finish, operating temperature range, and voltage rating. They are direct substitutes within the SSQ series.

Q: What determines substitution eligibility for SSQ rectangular connectors?

A: Substitution is valid when the following parameters match: connector type (receptacle), number of positions (10), mating pitch (0.100"), row spacing (0.100"), mounting type (through hole), termination method (solder), fastening type (push-pull), contact finish (gold), operating temperature range (-55°C to 125°C), and voltage rating (465VAC, 655VDC).

Q: Are there any compliance differences between these parts?

A: No. Both parts carry identical certifications: ROHS3 compliance, UL94 V-0 flammability rating, and EAR99 export classification. They meet the same regulatory and environmental standards.

Q: Can I use SSQ-105-01-F-D as a drop-in replacement for SSQ-105-21-F-D?

A: Yes. The parts are mechanically and electrically equivalent. No circuit redesign or PCB layout modification is required for substitution.

Q: What is the difference between the part numbers SSQ-105-21-F-D and SSQ-105-01-F-D?

A: The part numbers differ in the middle digit sequence (21 versus 01), but this variation does not affect the electrical or mechanical specifications provided in the engineering data. Both parts share the same base product number (SSQ-105) and belong to the same connector series.
