Key Parameters

Substitute Part Grouping Explanation

The SSW-108-21-L-D qualifies SSW-108-01-L-D as a direct substitute based on the following critical parameters:

• Identical connector type (Receptacle)
• Identical number of positions (16)
• Identical pitch spacing (0.100" / 2.54mm)
• Identical row configuration (2 rows at 0.100" spacing)
• Identical mounting method (Through Hole)
• Identical termination type (Solder)
• Identical contact finish specification (Gold mating surface)
• Identical current rating (4.7A per contact)
• Identical operating temperature range (-55°C ~ 125°C)
• Identical flammability rating (UL94 V-0)
• Identical RoHS compliance status (ROHS3 Compliant)

Both parts belong to the SSW series base product family (SSW-108), confirming mechanical and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both SSW-108-21-L-D and SSW-108-01-L-D are active production parts with full ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and moisture sensitivity requirements. The SSW-108-01-L-D offers higher stock availability (2500 units) compared to SSW-108-21-L-D (1116 units). For applications with moisture exposure concerns, the SSW-108-01-L-D provides defined moisture sensitivity level (MSL 1 - Unlimited), while SSW-108-21-L-D is rated as Not Applicable. Both parts maintain equivalent performance across all critical parameters including current rating, operating temperature range, and contact finish specifications.

Frequently Asked Questions (FAQ)

Q: Are SSW-108-21-L-D and SSW-108-01-L-D mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 16-position configuration, 0.100" pitch spacing, 2-row layout, through-hole mounting, and push-pull fastening. PCB footprints and mating interface dimensions are equivalent.

Q: Can these parts be used interchangeably in the same circuit design?

A: Yes. Electrical parameters are identical, including 4.7A per contact current rating, operating temperature range (-55°C ~ 125°C), contact material (Phosphor Bronze), and mating contact finish (Gold). Both parts support the same signal and power distribution requirements.

Q: What is the difference between SSW-108-21-L-D and SSW-108-01-L-D?

A: The primary differences are inventory availability and moisture sensitivity rating. SSW-108-01-L-D has higher stock (2500 units) and defined MSL rating (1 - Unlimited), while SSW-108-21-L-D has lower stock (1116 units) and MSL rated as Not Applicable. All functional and mechanical parameters are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both SSW-108-21-L-D and SSW-108-01-L-D are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: Which part should I select for moisture-sensitive applications?

A: SSW-108-01-L-D is specified with MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. SSW-108-21-L-D is rated as Not Applicable for MSL. For applications requiring explicit moisture sensitivity documentation, SSW-108-01-L-D is the appropriate selection.
