SSW-117-22-F-D-VS Equivalent & Substitute Parts

Part Overview

The SSW-117-22-F-D-VS is a 34-position receptacle connector manufactured by Samtec Inc., designed for board-to-board or cable applications with 0.100" (2.54mm) pitch spacing. This surface mount connector features gold-plated forked contacts rated for 4.7A per contact and operates across -55°C to 125°C. The product is active and widely stocked, with 955 units available in inventory. Alternative components may be required due to design flexibility, supply chain considerations, or specific application requirements where equivalent electrical and mechanical characteristics are acceptable.

Substitute Part Grouping Explanation

The NPPC172KFMS-RC from Sullins Connector Solutions qualifies as a substitute based on the following critical parameters:

Connector Position Count: Both parts feature 34 positions, enabling direct pin-to-pin compatibility
Mating Pitch: Both maintain 0.100" (2.54mm) pitch spacing and 0.100" row spacing, ensuring mechanical interchangeability
Mounting Configuration: Both are surface mount connectors with solder termination
Contact Finish: Both provide gold-plated mating contacts
Fastening Type: Both employ push-pull fastening mechanisms
Compliance: Both are ROHS3 compliant with UL94 V-0 flammability rating
Moisture Sensitivity: Both are MSL 1 (Unlimited)

The substitution is valid within the scope of these electrical and mechanical parameters. Differences in connector type (receptacle vs. header), contact current rating, and operating temperature range represent design trade-offs that must be evaluated for specific application requirements.

Engineering Selection Recommendations

Both the SSW-117-22-F-D-VS and NPPC172KFMS-RC are active products with ROHS3 compliance and UL94 V-0 flammability certification, ensuring regulatory alignment for industrial and commercial applications.

The SSW-117-22-F-D-VS supports higher current capacity at 4.7A per contact and operates across a wider temperature range (-55°C to 125°C), making it suitable for demanding thermal environments and high-current applications.

The NPPC172KFMS-RC provides a 250V voltage rating specification and operates within -40°C to 125°C, with a 3A per contact current rating. This configuration is appropriate for standard industrial applications where the reduced current capacity and narrower temperature range are acceptable.

Selection between these parts should be based on application-specific current requirements, operating temperature extremes, and voltage specifications. Both parts maintain identical mechanical compatibility through matching pitch, position count, and surface mount configuration.

Frequently Asked Questions (FAQ)

Q: Can NPPC172KFMS-RC directly replace SSW-117-22-F-D-VS in existing designs?

A: Mechanical and electrical compatibility exists for the 34-position, 0.100" pitch configuration. However, the NPPC172KFMS-RC has a lower current rating (3A vs. 4.7A per contact) and narrower operating temperature range (-40°C to 125°C vs. -55°C to 125°C). Verify that your application does not exceed these limits before substitution.

Q: What are the key differences between these connectors?

A: The SSW-117-22-F-D-VS is a receptacle with forked contacts, while the NPPC172KFMS-RC is a header with female socket contacts. The SSW-117-22-F-D-VS uses Liquid Crystal Polymer insulation; the NPPC172KFMS-RC uses Polyamide (PA6T). Current and temperature ratings differ as specified in the parameter comparison table.

Q: Are both parts suitable for surface mount assembly?

A: Yes, both connectors are surface mount components with solder termination, compatible with standard SMT assembly processes.

Q: Do both parts meet RoHS and flammability requirements?

A: Yes, both are ROHS3 compliant and carry UL94 V-0 flammability certification.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts are MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
