Key Parameters

Substitute Part Grouping Explanation

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

• Connector series (SSQ)
• Number of positions (10)
• Pitch spacing (0.100" / 2.54mm)
• Number of rows (2)
• Row spacing (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Termination method (Solder)
• Contact finish - mating (Gold)
• Operating temperature range (-55°C to 125°C)
• Voltage rating (465VAC, 655VDC)
• Material flammability (UL94 V-0)
• RoHS compliance (ROHS3)

The SSQ-105-01-L-D meets all substitution criteria and is classified as an equivalent part within the SSQ rectangular connector family.

Parameter Comparison

Engineering Selection Recommendations

Both SSQ-105-21-L-D and SSQ-105-01-L-D are active production parts manufactured by Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability: SSQ-105-01-L-D maintains higher stock levels (10238 units) compared to SSQ-105-21-L-D (1089 units). Both parts carry ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for equivalent applications. The parts are functionally interchangeable for board-to-board and cable connector applications within the specified operating temperature and voltage parameters.

Frequently Asked Questions (FAQ)

Q: Are SSQ-105-21-L-D and SSQ-105-01-L-D mechanically interchangeable?

A: Yes. Both connectors share identical mechanical dimensions, pitch spacing (0.100"), row configuration (2 rows), mounting type (through hole), and insulation height (0.335"). They are mechanically interchangeable in PCB layouts.

Q: Do these parts have the same electrical ratings?

A: Yes. Both parts are rated for 465VAC and 655VDC with identical contact materials (phosphor bronze), contact finishes (gold mating, tin post), and operating temperature range (-55°C to 125°C).

Q: What is the difference between these two part numbers?

A: The SSQ-105-21-L-D and SSQ-105-01-L-D are variants within the same SSQ series with identical specifications. Differences are limited to internal manufacturing designations and moisture sensitivity level (MSL) classification: SSQ-105-21-L-D is not applicable for MSL, while SSQ-105-01-L-D is classified as MSL 1 (Unlimited).

Q: Are both parts RoHS compliant?

A: Yes. Both SSQ-105-21-L-D and SSQ-105-01-L-D are ROHS3 compliant and carry UL94 V-0 flammability certification.

Q: Can I use SSQ-105-01-L-D as a direct replacement for SSQ-105-21-L-D?

A: Yes. The SSQ-105-01-L-D is a direct functional and mechanical equivalent. Selection may be based on supply chain availability and lead time requirements.
