SSW-103-22-F-S-VS Equivalent & Substitute Parts

Part Overview

The SSW-103-22-F-S-VS is a 3-position rectangular receptacle connector manufactured by Samtec Inc., designed for surface mount board-to-board or cable applications. This connector features a 0.100" (2.54mm) pitch, gold-plated mating contacts, and operates across -55°C to 125°C. The part maintains Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part is unavailable or when design requirements permit alternative connector architectures.

Key Parameters

Substitute Part Grouping Explanation

The NPPC031KFXC-RC from Sullins Connector Solutions qualifies as a substitute based on the following alignment of critical parameters:

• Connector Position Count: Both parts accommodate 3 positions
• Mating Pitch: Both maintain 0.100" (2.54mm) spacing
• Surface Mount Configuration: Both are surface mount termination types
• Gold Mating Contact Finish: Both feature gold-plated mating surfaces
• Solder Termination: Both use solder attachment to PCB
• Push-Pull Fastening: Both employ push-pull mating mechanisms
• Flammability Compliance: Both meet UL94 V-0 material standards
• RoHS3 Compliance: Both are RoHS3 compliant

The primary architectural difference is connector type: SSW-103-22-F-S-VS is a receptacle (female), while NPPC031KFXC-RC is a header with female socket contacts. This distinction requires mating interface compatibility verification in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

Both the SSW-103-22-F-S-VS and NPPC031KFXC-RC maintain Active product status with full RoHS3 compliance and UL94 V-0 flammability certification, supporting long-term design viability and regulatory adherence.

Selection between these parts depends on application-specific requirements:

The SSW-103-22-F-S-VS supports higher current capacity (4.7A per contact versus 3A) and extended operating temperature range (-55°C to 125°C versus -40°C to 105°C). Applications requiring these elevated electrical or thermal specifications necessitate the Samtec part.

The NPPC031KFXC-RC provides a substitute option when the connector architecture permits header-type mating and when operating conditions remain within -40°C to 105°C and 3A per contact limits. The Sullins part uses polyamide insulation material versus the LCP material in the Samtec part, with corresponding differences in insulation height (0.280" versus 0.335").

Both parts employ identical 0.100" pitch, gold mating contact finish, solder termination, and push-pull fastening, establishing the foundation for mechanical and electrical interchangeability within the stated parameter boundaries.

Frequently Asked Questions (FAQ)

Q: Can NPPC031KFXC-RC directly replace SSW-103-22-F-S-VS in all applications?

A: Direct replacement requires verification of three factors: (1) mating interface compatibility—the receptacle versus header architecture must align with the complementary connector in the circuit; (2) current requirements must not exceed 3A per contact; (3) operating temperature must remain within -40°C to 105°C. Applications exceeding these parameters require the original SSW-103-22-F-S-VS specification.

Q: What is the significance of the connector type difference (receptacle versus header)?

A: The SSW-103-22-F-S-VS is a receptacle (female connector), while the NPPC031KFXC-RC is a header with female socket contacts. The mating interface in the application circuit determines which type is appropriate. If the existing design uses male pins or male header connectors, the receptacle is required. If the design uses male socket connectors, the header may be compatible.

Q: Are there differences in insulation material that affect performance?

A: The SSW-103-22-F-S-VS uses Liquid Crystal Polymer (LCP) insulation with 0.335" height, while the NPPC031KFXC-RC uses Polyamide (PA6T/Nylon 6T) with 0.280" height. Both materials meet UL94 V-0 flammability standards. Material selection affects mechanical properties and thermal performance; applications with specific insulation material requirements must specify the appropriate part.

Q: What are the current and voltage limitations for substitution?

A: The SSW-103-22-F-S-VS supports 4.7A per contact with unspecified voltage rating. The NPPC031KFXC-RC supports 3A per contact at 250V. Substitution is valid only when circuit current does not exceed 3A per contact. If the application requires 250V rating confirmation, the Sullins part explicitly provides this specification.

Q: Are both parts suitable for high-temperature applications?

A: The SSW-103-22-F-S-VS operates from -55°C to 125°C, supporting extended temperature range applications. The NPPC031KFXC-RC operates from -40°C to 105°C. Applications requiring operation below -40°C or above 105°C must use the Samtec part.

Q: Do both parts meet current regulatory compliance standards?

A: Both parts are RoHS3 compliant and meet UL94 V-0 material flammability requirements, supporting current regulatory environments. Both maintain Active product status, ensuring continued availability and support.
