Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSW-111-21-G-S is determined by strict equivalence across the following critical parameters:

• Connector Type & Position Count: Receptacle configuration with 11 positions
• Pitch & Mounting: 0.100" (2.54mm) mating pitch with through-hole mounting
• Contact Specifications: Forked contact type with gold plating on mating surfaces
• Electrical Performance: 4.7A per contact current rating
• Environmental Compliance: UL94 V-0 flammability rating and ROHS3 compliance
• Termination Method: Solder termination with push-pull fastening

The substitute part SSW-111-01-G-S meets all these criteria and belongs to the same SSW series base product family (SSW-111).

Parameter Comparison

Engineering Selection Recommendations

Both SSW-111-21-G-S and SSW-111-01-G-S are active production parts from Samtec Inc. with identical electrical, mechanical, and environmental specifications. Selection between these parts should be based on:

• Inventory Availability: SSW-111-01-G-S offers higher stock levels (3,950 units versus 1,087 units), providing greater supply security.
• Compliance Status: Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for equivalent applications.
• Supply Chain Continuity: Both parts share the same base product number (SSW-111) and series designation, ensuring design compatibility and long-term availability within the SSW connector family.

Frequently Asked Questions (FAQ)

Q: Can SSW-111-01-G-S be used as a direct replacement for SSW-111-21-G-S?

A: Yes. Both parts are functionally equivalent receptacle connectors with identical pin counts (11 positions), mating pitch (0.100"), contact specifications, current ratings (4.7A per contact), and operating temperature ranges (-55°C to 125°C). They share the same series designation and base product number.

Q: Are there any mechanical compatibility concerns when substituting between these parts?

A: No. Both connectors have identical insulation heights (0.335"), contact lengths (0.104"), and mounting configurations (through-hole solder termination with push-pull fastening). PCB footprints and mating interfaces are equivalent.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both SSW-111-21-G-S and SSW-111-01-G-S are ROHS3 compliant, carry UL94 V-0 flammability ratings, and share identical ECCN (EAR99) and HTSUS classifications.

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

A: The parts are functionally identical. The difference in part numbers reflects internal Samtec product line designations. SSW-111-01-G-S currently has higher inventory availability (3,950 units in stock).

Q: Are contact finish specifications identical?

A: Yes. Both parts feature gold-plated mating contacts with 20.0µin (0.51µm) thickness and gold-plated posts with 3.00µin (0.076µm) thickness, ensuring equivalent electrical performance and contact reliability.
