Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSW-122-01-S-T is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Position count (66 positions)
• Pitch specification (0.100" / 2.54mm mating pitch)
• Row configuration (3 rows with 0.100" row spacing)
• Mounting method (Through Hole)
• Termination type (Solder)
• Contact finish on mating surface (Gold, 30.0µin thickness)
• Operating temperature range (-55°C ~ 125°C)
• Current rating (4.7A per contact)
• Insulation material (Liquid Crystal Polymer)
• Flammability compliance (UL94 V-0)
• RoHS compliance (ROHS3)

The SSW-122-21-SM-T meets all substitution criteria within the SSW series, maintaining identical electrical performance and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both SSW-122-01-S-T and SSW-122-21-SM-T are Active products with identical electrical specifications, mechanical dimensions, and regulatory compliance. Selection between these parts is based on availability and supply chain requirements. Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting the same regulatory standards. The SSW-122-21-SM-T currently shows higher inventory availability (791 Pcs vs. 670 Pcs), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can SSW-122-21-SM-T replace SSW-122-01-S-T in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent within the SSW series. They share identical pitch spacing (0.100"), position count (66), row configuration (3 rows), contact ratings (4.7A per contact), operating temperature range (-55°C to 125°C), and insulation material (LCP). Both maintain the same gold contact finish specification and UL94 V-0 compliance.

Q: Are there differences in the part numbers that affect compatibility?

A: The part number variations (01-S-T vs. 21-SM-T) reflect internal Samtec designations within the SSW series but do not indicate functional differences for the specified parameters. Both parts are receptacle connectors with identical mating and row spacing.

Q: What is the significance of the through-hole mounting specification?

A: Through-hole mounting indicates both parts are designed for PCB insertion with solder termination. This mounting type is consistent across both parts and determines PCB layout compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SSW-122-01-S-T and SSW-122-21-SM-T are ROHS3 compliant and carry UL94 V-0 flammability ratings, meeting identical regulatory requirements.
