Substitute Part Grouping Explanation

Substitution eligibility for the SSW-117-21-F-D is determined by strict equivalence across the following critical parameters:

Connector Type & Position Count: All substitutes must be receptacle connectors with 34 positions
Pitch & Row Configuration: Mating pitch of 0.100" (2.54mm) with 2-row configuration and 0.100" row spacing
Mounting & Termination: Through-hole solder termination required
Contact Specifications: Forked contact geometry with gold mating finish (3.00µin thickness) and phosphor bronze material
Electrical Performance: 4.7A per contact current rating maintained across all substitutes
Environmental Compliance: UL94 V-0 flammability rating and ROHS3 compliance required
Operating Range: -55°C to 125°C temperature specification

The three identified substitutes (SSW-117-01-F-D, SSW-117-01-FM-D, SSW-117-21-FM-D) meet all critical electrical and mechanical parameters. Variations exist only in fastening mechanism designation (F vs. FM suffix) and moisture sensitivity level classification, which do not affect functional interchangeability in standard applications.

Engineering Selection Recommendations

All four parts (SSW-117-21-F-D, SSW-117-01-F-D, SSW-117-01-FM-D, SSW-117-21-FM-D) are active production items from Samtec Inc. and maintain full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on:

Inventory Availability: SSW-117-01-F-D offers the highest stock level (1,895 units), followed by SSW-117-01-FM-D (1,038 units), SSW-117-21-FM-D (759 units), and SSW-117-21-F-D (694 units).

Moisture Sensitivity Classification: SSW-117-01-F-D is classified as MSL 1 (Unlimited), while SSW-117-21-F-D and SSW-117-01-FM-D are classified as Not Applicable. SSW-117-21-FM-D is classified as Not Applicable. This distinction affects storage and handling requirements but does not impact electrical or mechanical performance.

Regulatory Compliance: All substitutes maintain equivalent export classification (EAR99) and tariff coding (8536.69.4040), supporting consistent supply chain documentation.

Frequently Asked Questions (FAQ)

Q: Are SSW-117-01-F-D, SSW-117-01-FM-D, and SSW-117-21-FM-D electrically and mechanically interchangeable with SSW-117-21-F-D?

A: Yes. All four parts share identical electrical specifications (34 positions, 0.100" pitch, 4.7A per contact, -55°C to 125°C operating range) and mechanical dimensions (through-hole mounting, forked contacts, gold mating finish, LCP insulation). Functional interchangeability is confirmed across all critical parameters.

Q: What is the difference between the F and FM designations in the part numbers?

A: The F and FM suffixes indicate variations in fastening mechanism designation within the SSW-117 series. Both configurations maintain identical electrical performance, contact geometry, and pitch specifications. The designation does not affect PCB layout or mating compatibility.

Q: Does moisture sensitivity level affect part selection for standard applications?

A: Moisture sensitivity level (MSL) classification affects storage, handling, and shelf-life management but does not impact electrical or mechanical performance. Parts classified as MSL 1 (Unlimited) or Not Applicable can be used interchangeably in applications without special moisture control requirements.

Q: Can these parts be used in high-temperature applications?

A: All four substitutes are rated for -55°C to 125°C operating temperature with UL94 V-0 flammability certification, supporting use in industrial and automotive environments within this temperature range.

Q: Are there any compliance or export restrictions affecting these parts?

A: All parts are classified as EAR99 for export control purposes and carry ROHS3 compliance certification. No additional regulatory restrictions apply to standard commercial applications.
