SSW-105-21-F-D Equivalent & Substitute Parts

Part Overview

The SSW-105-21-F-D is a 10 Position Receptacle Connector manufactured by Samtec Inc., designed for 0.100" (2.54mm) pitch board-to-board or cable applications. This through-hole connector features gold-plated mating contacts, forked contact design, and push-pull fastening. The part is Active status and ROHS3 compliant, making it suitable for applications requiring reliable rectangular connector solutions with standard 0.1" spacing.

Substitute parts are identified when design requirements allow flexibility in row spacing configuration or contact post finish specifications while maintaining core electrical and mechanical compatibility.

Identical Parameters (Non-Negotiable):

• Manufacturer: Samtec Inc.
• Series: SSW
• Number of Positions: 10
• Pitch - Mating: 0.100" (2.54mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Connector Type: Receptacle
• Contact Type: Forked
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Finish - Mating: Gold
• Current Rating: 4.7A per Contact
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• Insulation Material: Liquid Crystal Polymer (LCP)
• Contact Material: Phosphor Bronze

Variable Parameters (Substitution Basis):

The three substitute parts differ only in row spacing configuration and contact post finish specifications, maintaining full electrical and mechanical compatibility with the main part.

Parameter Comparison

Engineering Selection Recommendations

All four parts—SSW-105-21-F-D, SSW-105-01-F-D, SSW-105-01-FM-D, and SSW-105-21-FM-D—maintain Active product status and ROHS3 compliance. Selection between these parts depends on specific design requirements regarding row spacing configuration and contact post finish specifications.

The SSW-105-21-F-D and SSW-105-21-FM-D share identical row spacing configuration (21 designation) and differ only in contact post finish. The SSW-105-01-F-D and SSW-105-01-FM-D share identical row spacing configuration (01 designation) and differ only in contact post finish.

All parts are electrically and mechanically interchangeable within their respective row spacing groups, provided the mating connector and PCB layout accommodate the selected configuration. Inventory availability ranges from 760 to 1659 pieces across all four parts.

Frequently Asked Questions (FAQ)

Q: What is the difference between SSW-105-21-F-D and SSW-105-01-F-D?

A: Both parts are 10-position receptacle connectors with 0.100" pitch and identical electrical ratings. The primary difference is the row spacing configuration indicated by the "21" versus "01" designation in the part number. This affects the physical layout and spacing of the connector rows on the PCB. The contact post finish (F designation) is identical for both.

Q: Can I substitute SSW-105-21-F-D with SSW-105-21-FM-D?

A: Yes. Both parts share the same row spacing configuration (21 designation) and differ only in contact post finish specification. The FM designation indicates a different post finish treatment compared to the F designation. All other electrical and mechanical parameters remain identical.

Q: Are all four parts electrically compatible?

A: All four parts maintain identical electrical specifications: 4.7A per contact current rating, -55°C to 125°C operating temperature range, and gold-plated mating contacts with 3.00µin thickness. Substitution is based on mechanical compatibility with your specific PCB layout and mating connector configuration.

Q: What does the row spacing configuration affect?

A: Row spacing configuration (01 vs. 21) determines the physical distance between connector rows on the PCB. This affects PCB layout, mating connector compatibility, and overall connector footprint. Ensure your PCB design and mating connector accommodate the selected row spacing configuration.

Q: Are all parts ROHS3 compliant?

A: Yes. All four parts—SSW-105-21-F-D, SSW-105-01-F-D, SSW-105-01-FM-D, and SSW-105-21-FM-D—are ROHS3 compliant and maintain Active product status.

Q: Which part has the highest inventory availability?

A: SSW-105-01-F-D has the highest inventory with 1659 pieces in stock, followed by SSW-105-21-FM-D with 947 pieces, SSW-105-21-F-D with 941 pieces, and SSW-105-01-FM-D with 760 pieces.
