Substitute Part Grouping Explanation

Substitute parts for the 91763-328 are qualified based on the following critical parameters that must match or exceed the original specification:

Connector Type: Receptacle, Bottom Entry configuration
Position Count: 28 positions
Pitch Spacing: 0.079" (2.00mm) mating pitch with 0.079" (2.00mm) row spacing
Mounting: Surface mount with solder termination
Contact Finish: Gold-plated mating surface
Operating Temperature Range: -55°C to 125°C minimum
Flammability Rating: UL94 V-0 minimum
Fastening Type: Push-Pull mechanism

The Samtec CLT series receptacles meet these core requirements. Variations within the CLT-114 family differ in contact finish thickness, insulation material composition, and post-contact finish specifications, which do not affect primary electrical or mechanical compatibility for board-to-board applications.

Engineering Selection Recommendations

Primary Substitutes (Active Status, RoHS3 Compliant):

CLT-114-02-F-D-BE, CLT-114-02-L-D-BE, CLT-114-02-L-D-BE-A-K, and CLT-114-02-S-D-BE are the preferred substitutes. All are manufactured by Samtec Inc., maintain active product status, and comply with ROHS3 regulations. These parts are functionally equivalent for board-to-board applications requiring 28-position, 0.079" pitch receptacle connectors with bottom entry configuration and gold-plated contacts.

Secondary Substitute (Non-Bottom Entry):

CLT-114-02-F-D is suitable only for applications where bottom entry configuration is not required. This part maintains all other critical specifications but lacks the bottom entry feature of the original 91763-328.

Discontinued Part (Not Recommended for New Designs):

CLT-114-02-G-D is discontinued at DiGi Electronics and should not be selected for new production designs, despite meeting electrical and mechanical specifications.

Packaging Considerations:

CLT-114-02-L-D-BE-A-K is supplied in bulk packaging with pick-and-place features, suitable for high-volume automated assembly operations. Standard tube packaging is available for CLT-114-02-F-D-BE, CLT-114-02-L-D-BE, and CLT-114-02-S-D-BE.

Frequently Asked Questions (FAQ)

Q: Can CLT-114-02-F-D be used as a direct replacement for 91763-328?

A: CLT-114-02-F-D meets all electrical and mechanical specifications except connector type. The original 91763-328 specifies bottom entry configuration, while CLT-114-02-F-D is a standard receptacle without bottom entry. Use CLT-114-02-F-D only if your PCB layout does not require bottom entry mating.

Q: What is the difference between CLT-114-02-L-D-BE and CLT-114-02-S-D-BE?

A: Both parts are 28-position, bottom entry receptacles with identical electrical and mechanical specifications. The primary difference is contact finish thickness on the mating surface: CLT-114-02-L-D-BE has 10.0µin (0.25µm) gold plating, while CLT-114-02-S-D-BE has 30.0µin (0.76µm) gold plating. CLT-114-02-S-D-BE provides thicker gold plating for applications requiring enhanced wear resistance.

Q: Is CLT-114-02-G-D-BE a viable substitute?

A: CLT-114-02-G-D-BE meets all technical specifications and is currently active in production. However, CLT-114-02-G-D (the non-bottom entry variant) is discontinued at DiGi Electronics. For new designs, select CLT-114-02-F-D-BE, CLT-114-02-L-D-BE, or CLT-114-02-S-D-BE to ensure long-term supply availability.

Q: What does the "-A-K" suffix in CLT-114-02-L-D-BE-A-K indicate?

A: The "-A-K" suffix indicates bulk packaging with board guide and pick-and-place features. This variant is designed for automated assembly processes and high-volume production. Standard tube-packaged alternatives are available if automated handling features are not required.

Q: Are all substitute parts RoHS compliant?

A: All Samtec CLT-114 substitutes listed are ROHS3 compliant. The original 91763-328 is RoHS non-compliant. If RoHS compliance is a design requirement, any of the listed Samtec substitutes satisfy this requirement.

Q: What is the current rating difference between 91763-328 and the CLT-114 substitutes?

A: The original 91763-328 is rated for 1A total current at 200V. The CLT-114 substitutes are rated for 4.1A per contact, providing significantly higher current capacity per individual contact position.
