FS1-R38-3000 QSFP Receptacle Connector Equivalent & Substitute Parts

Part Overview

The FS1-R38-3000 is a 38 Position QSFP Receptacle Connector manufactured by Amphenol ICC (Commercial Products) in the ExpressPort™ QSFP+ series. This surface mount, right angle solder connector features a board guide and gold-plated contacts. The part is Active in product status with 1075 pieces currently in stock.

Identifying equivalent and substitute parts is necessary when the primary part becomes unavailable, when supply chain optimization is required, or when design flexibility allows for alternative qualified components that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution between the FS1-R38-3000 and equivalent parts is determined by strict alignment of the following critical parameters:

Electrical Compatibility Parameters:

• Connector Type: QSFP or QSFP+ (both support 38-position configuration)
• Number of Positions: 38 (exact match required)
• Termination Method: Solder (ensures PCB integration compatibility)

Mechanical Compatibility Parameters:

• Connector Style: Receptacle (functional role match)
• Mounting Type: Surface Mount, Right Angle (board layout and orientation compatibility)
• Features: Board Guide (mechanical alignment and stability)
• Packaging: Cut Tape (CT) (handling and assembly process compatibility)

Environmental & Compliance Parameters:

• Moisture Sensitivity Level: 1 (Unlimited) (storage and handling requirements)
• RoHS Status: RoHS Compliant or ROHS3 Compliant (regulatory alignment)

Parts meeting all these criteria are classified as direct substitutes and can be selected based on availability, inventory levels, and supply chain considerations.

Parameter Comparison

Engineering Selection Recommendations

FS1-R38-3000 (Amphenol ICC) is the primary part specification. Selection of this part is appropriate when:

• Amphenol ICC supply chain is preferred or established
• Existing designs are qualified to this specific manufacturer
• Current inventory levels meet project timelines

2110819-1 (TE Connectivity AMP Connectors) is a qualified substitute. Selection of this part is appropriate when:

• FS1-R38-3000 availability is constrained
• TE Connectivity supply chain offers cost or logistics advantages
• Design specifications allow for QSFP+ variant compatibility
• Higher inventory availability (2702 pieces) supports accelerated procurement

Both parts are Active in product status, RoHS compliant, and carry identical ECCN and HTSUS classifications. Both maintain MSL 1 (Unlimited) moisture sensitivity ratings, indicating equivalent storage and handling requirements. The primary technical distinction is the QSFP versus QSFP+ connector type designation; both support 38-position configurations with identical mechanical and electrical mounting characteristics.

Frequently Asked Questions (FAQ)

Q: What is the difference between QSFP and QSFP+ connector types in this application?

A: Both QSFP and QSFP+ are 38-position receptacle connectors with identical mechanical form factors, mounting orientations, and solder termination methods. The designation reflects protocol generation support; both are compatible with 38-position receptacle applications in surface mount, right angle configurations.

Q: Can FS1-R38-3000 and 2110819-1 be used interchangeably on the same PCB?

A: Yes. Both connectors share identical mechanical specifications: 38 positions, surface mount right angle mounting, solder termination, board guide features, and Cut Tape packaging. PCB footprints and assembly processes are compatible.

Q: Are there any compliance differences between the two parts?

A: Both parts are RoHS compliant (FS1-R38-3000 is RoHS Compliant; 2110819-1 is ROHS3 Compliant). Both carry EAR99 ECCN classification and 8536.69.4040 HTSUS codes. Both maintain MSL 1 (Unlimited) moisture sensitivity levels. The TE Connectivity part includes REACH Unaffected status in its documentation.

Q: What factors should determine which substitute part to select?

A: Selection should be based on: (1) supply chain availability and lead times, (2) inventory levels (TE Connectivity currently has 2702 pieces versus 1075 for Amphenol ICC), (3) established supplier relationships, (4) cost considerations, and (5) existing design qualifications. All electrical and mechanical parameters are equivalent.

Q: Does packaging format affect substitution eligibility?

A: No. Both parts are supplied in Cut Tape (CT) packaging, which is identical for handling, storage, and automated assembly processes. Packaging format is a substitution requirement match.

Q: Are contact finish specifications equivalent between the two parts?

A: The FS1-R38-3000 specifies gold contact finish at 15.0µin (0.38µm) thickness. The 2110819-1 contact finish specifications are not provided in the available documentation. Contact finish data should be verified through the respective manufacturer datasheets if contact material specifications are critical to the application.
