Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSW-112-21-L-D is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Number of positions (24)
• Pitch spacing (0.100" / 2.54mm)
• Number of rows (2)
• Row spacing (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Termination type (Solder)
• Contact finish at mating surface (Gold)
• Current rating per contact (4.7A)
• Operating temperature range (-55°C ~ 125°C)
• Flammability rating (UL94 V-0)
• RoHS compliance status (ROHS3 Compliant)

The SSW-112-01-L-D meets all these criteria and is classified as a direct substitute within the SSW series.

Parameter Comparison

Engineering Selection Recommendations

Both the SSW-112-21-L-D and SSW-112-01-L-D are active production parts manufactured by Samtec Inc. and maintain full ROHS3 compliance. The SSW-112-01-L-D carries a Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), compared to the main part's Not Applicable designation. Both parts are classified under ECCN EAR99 and share identical HTSUS codes. Selection between these parts should be based on inventory availability and specific moisture handling requirements for your application environment.

Frequently Asked Questions (FAQ)

Q: Can SSW-112-01-L-D be used as a direct replacement for SSW-112-21-L-D?

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

A: The primary documented difference is the Moisture Sensitivity Level (MSL) rating. The SSW-112-01-L-D has an MSL of 1 (Unlimited), while the SSW-112-21-L-D is listed as Not Applicable. All other electrical, mechanical, and compliance parameters are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both SSW-112-21-L-D and SSW-112-01-L-D are ROHS3 compliant.

Q: What is the current-carrying capacity of these connectors?

A: Each contact is rated for 4.7A maximum current.

Q: What is the operating temperature range?

A: Both connectors operate across -55°C to 125°C.

Q: What contact finish is used for mating surfaces?

A: Gold plating at 10.0µin (0.25µm) thickness is applied to all mating contacts.

Q: Are these connectors suitable for through-hole PCB assembly?

A: Yes. Both parts feature through-hole solder termination for direct PCB mounting.
