Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FS1-R26-2001 are identified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Connector Type: SAS, Mini (exact match required)
• Connector Style: Receptacle (exact match required)
• Number of Positions: 26 (exact match required)
• Mounting Type: Surface Mount, Right Angle (exact match required)
• Termination Method: Solder (exact match required)
• Contact Finish: Gold (exact match required)
• Contact Finish Thickness: 30.0µin (0.76µm) (exact match required)

The substitute part 1761987-7 manufactured by TE Connectivity AMP Connectors meets all critical parameters and is therefore classified as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The FS1-R26-2001 is designated Last Time Buy, indicating end-of-life status with no future production planned. The substitute part 1761987-7 is classified as Active product status, ensuring ongoing availability and supply chain continuity.

Both parts satisfy identical electrical and mechanical specifications for Mini SAS 26-position receptacle connector applications. Both achieve RoHS compliance (FS1-R26-2001: RoHS Compliant; 1761987-7: ROHS3 Compliant) and share identical contact finish specifications, moisture sensitivity ratings, and export classification codes.

The primary distinction between these parts is packaging format: FS1-R26-2001 is supplied in Cut Tape (CT) format, while 1761987-7 is supplied in Tape & Reel (TR) format. This packaging difference does not affect electrical or mechanical performance and is determined by procurement volume and assembly process requirements.

For new designs or applications requiring long-term component availability, 1761987-7 is the appropriate selection due to Active product status.

Frequently Asked Questions (FAQ)

Q: Can 1761987-7 be used as a direct replacement for FS1-R26-2001 in existing designs?

A: Yes. Both connectors meet identical specifications for connector type, position count, mounting configuration, termination method, and contact finish. Electrical and mechanical compatibility is confirmed.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape packaging supplies individual connector units cut from a continuous tape, typically used for lower-volume orders or manual assembly. Tape & Reel packaging supplies connectors on continuous reels, optimized for high-volume automated assembly processes. Both packaging formats contain identical connector components.

Q: Are there compliance differences between the two parts?

A: Both parts are RoHS compliant. FS1-R26-2001 carries RoHS Compliant status, while 1761987-7 carries ROHS3 Compliant status. Both meet current regulatory requirements. Both share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: Why is FS1-R26-2001 designated Last Time Buy?

A: Last Time Buy designation indicates the manufacturer has discontinued production of this part number. Existing inventory is available for purchase, but no future production runs are planned. This status necessitates identification of equivalent active alternatives for long-term supply assurance.

Q: What is Moisture Sensitivity Level (MSL) 1?

A: MSL 1 indicates unlimited shelf life without moisture control requirements. Both parts carry this rating, meaning they do not require special dry storage or handling procedures.

Q: Are the board guide and solder retention features functionally equivalent between the two parts?

A: Both parts include board guide features. FS1-R26-2001 specifies both board guide and solder retention features, while 1761987-7 specifies board guide. Both provide mechanical positioning and retention on the circuit board assembly.
