Engineering Selection Recommendations

For Direct Amphenol ICC Replacement: Select 91763-316LF when maintaining the Minitek® series is required. This part is functionally equivalent to the obsolete 91763-316 with identical mechanical dimensions and electrical ratings. The primary advantage is active product status and RoHS compliance. The contact finish thickness on mating surfaces remains at 15.0µin (0.38µm), matching the original specification.

For Cross-Manufacturer Substitution: Samtec CLT-108 series connectors provide full electrical and mechanical compatibility with enhanced performance characteristics. All CLT variants meet the critical substitution parameters: 16-position, 0.079" pitch, bottom entry configuration, surface mount, push-pull fastening, and gold mating finish. Key differentiators include:

Current Rating Enhancement: CLT series rated at 4.1A per contact versus 1A on the original part, providing design margin for higher-current applications
RoHS3 Compliance: All CLT variants meet ROHS3 standards, supporting modern supply chain requirements
Insulation Material: LCP insulation in CLT series offers improved thermal and mechanical properties compared to plastic
Contact Material: Phosphor bronze contacts in CLT series provide alternative material composition while maintaining electrical performance

Packaging Selection for CLT Series:

Tube packaging: CLT-108-02-F-D, CLT-108-02-F-D-A, CLT-108-02-F-D-BE, CLT-108-02-F-D-BE-A, CLT-108-02-F-D-BE-A-P for manual assembly or small-volume production
Tape & Reel (TR): CLT-108-02-F-D-A-P-TR for automated pick-and-place assembly
Cut Tape (CT): CLT-108-02-F-D-BE-A-K-TR for high-volume automated production with maximum inventory availability (5837 pcs)

Frequently Asked Questions (FAQ)

Q: Can CLT-108 series connectors directly replace the 91763-316 in existing designs? A: Yes. All CLT-108 variants maintain the critical mechanical and electrical parameters: 16 positions, 0.079" (2.00mm) pitch, 2-row configuration, surface mount, push-pull fastening, and gold mating finish. The connectors are mechanically and electrically interchangeable. Verify board layout accommodates the 0.083" (2.10mm) insulation height of CLT series versus 0.091" (2.30mm) on the original part.

Q: What is the difference between 91763-316LF and the original 91763-316? A: The primary differences are product status (active vs. obsolete) and RoHS compliance (compliant vs. non-compliant). The 91763-316LF maintains identical electrical ratings (1A, 200V), mechanical configuration, and contact finish thickness (15.0µin). The contact post finish changes from tin-lead to gold.

Q: Why do CLT-108 connectors have higher current ratings (4.1A) than the original part (1A)? A: The CLT-108 series is engineered with phosphor bronze contacts and LCP insulation material, which support higher current density. The 4.1A rating reflects the contact design and material composition of the CLT series. Applications requiring only 1A operation remain fully compatible.

Q: Which packaging option should be selected for high-volume production? A: CLT-108-02-F-D-BE-A-K-TR in Cut Tape (CT) packaging provides the highest inventory availability (5837 pcs) and is optimized for automated pick-and-place assembly. This variant includes board guide and pick-and-place features.

Q: Are there compliance differences between substitute options? A: The 91763-316 is RoHS non-compliant. The 91763-316LF is RoHS compliant. All Samtec CLT-108 variants are ROHS3 compliant. For applications requiring REACH compliance, CLT-108-02-F-D-BE-A is marked as REACH Affected; all other CLT variants are REACH Unaffected.

Q: What is the impact of different contact finish thicknesses? A: The original 91763-316 and 91763-316LF specify 15.0µin (0.38µm) gold plating on mating contacts. CLT-108 series specifies 3.00µin (0.076µm). Both thicknesses meet industry standards for gold-plated contacts and provide equivalent electrical performance and corrosion resistance for the specified operating conditions.

Q: Can CLT-108 connectors be used in applications with the original 200V voltage rating? A: CLT-108 variants do not specify a voltage rating in the provided data. Verify voltage rating compatibility with Samtec technical documentation before application in circuits exceeding 200V.

Q: What is the difference between bottom entry and standard receptacle configurations? A: Bottom entry connectors route mating contacts from the bottom surface of the connector body, enabling cable or connector entry from below the PCB plane. Standard receptacles route contacts from the top. The 91763-316 and CLT-108-02-F-D-BE variants are bottom entry. CLT-108-02-F-D, CLT-108-02-F-D-A, and CLT-108-02-F-D-A-P are standard receptacles without bottom entry configuration.
