SSW-110-01-F-D-N Equivalent & Substitute Parts

Part Overview

The SSW-110-01-F-D-N is a 20-position rectangular receptacle connector manufactured by Samtec Inc., designed for board-to-board or cable applications with 0.100" (2.54mm) pitch through-hole mounting. This connector features gold-plated mating contacts, forked contact design, and solder termination with push-pull fastening. The part is active in production status with 937 units currently in stock.

Substitute parts are necessary when the primary part number becomes unavailable, when inventory levels require sourcing alternatives, or when design flexibility permits selection from equivalent configurations within the SSW-110 series.

Substitute Part Grouping Explanation

Substitution within the SSW-110 series is determined by strict equivalence across the following critical parameters:

Connector Type & Position Count: All substitutes maintain receptacle configuration with 20 positions
Pitch & Row Configuration: All maintain 0.100" (2.54mm) mating pitch and 2-row layout with 0.100" row spacing
Mounting & Termination: All use through-hole mounting with solder termination
Contact Specifications: All feature forked contacts with gold mating finish and tin post finish
Electrical Performance: All rated at 4.7A per contact with identical operating temperature range (-55°C ~ 125°C)
Material & Compliance: All use LCP insulation, UL94 V-0 flammability rating, and ROHS3 compliance

The four substitute parts differ only in fastening mechanism designation (01 vs. 21) and contact material designation (F vs. FM), which represent internal design variations within the SSW-110 base product family that do not affect electrical or mechanical compatibility for standard board-to-board applications.

Engineering Selection Recommendations

All five parts maintain active production status with Samtec Inc. and carry ROHS3 compliance certification. Selection among these equivalents should be based on inventory availability and lead time requirements:

SSW-110-01-F-D offers the highest inventory level at 2504 units, providing optimal availability for immediate procurement
SSW-110-01-FM-D provides 1111 units in stock with equivalent electrical and mechanical specifications
SSW-110-21-F-D and SSW-110-21-FM-D offer 847 and 888 units respectively

All parts are suitable for direct substitution in applications requiring 20-position, 0.100" pitch rectangular receptacle connectors with gold mating contacts and through-hole solder termination. No design modifications or PCB layout changes are required when substituting between these part numbers.

Frequently Asked Questions (FAQ)

Q: Can SSW-110-01-F-D-N be directly replaced with SSW-110-01-F-D?

A: Yes. Both parts share identical electrical ratings (4.7A per contact), operating temperature range (-55°C ~ 125°C), connector geometry (20 positions, 0.100" pitch, 2 rows), contact configuration (forked, gold mating finish), and mounting method (through-hole solder). The primary difference is packaging designation, which does not affect functional compatibility.

Q: What is the difference between the "01" and "21" designations in the part number?

A: The "01" and "21" designations represent internal fastening mechanism variations within the SSW-110 series. Both configurations maintain identical electrical performance, contact ratings, and mechanical dimensions. Selection between these variants is determined by application-specific fastening requirements, not by electrical or thermal specifications.

Q: Are the "F" and "FM" contact material designations interchangeable?

A: Yes. Both designations represent forked contact configurations within the SSW-110 series that maintain equivalent electrical performance and current ratings. The material designation variation does not affect compatibility in standard board-to-board connector applications.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All five parts carry ROHS3 compliance certification, UL94 V-0 flammability rating, and active production status. All are manufactured by Samtec Inc. and meet identical environmental and regulatory requirements.

Q: Can these connectors be used interchangeably on the same PCB?

A: Yes. All parts maintain identical through-hole mounting footprints, solder pad configurations, and mechanical envelope dimensions. No PCB redesign or layout modification is required when substituting between these part numbers.
