Amphenol ICC 91596-110 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 91596-110 is a 10-position receptacle connector with 0.079" (2.00mm) pitch, designed for surface mount applications in the Minitek® 2.00mm series. This connector features bottom entry configuration, gold-plated mating contacts, and push-pull fastening. The part is currently obsolete with 977 pieces in stock inventory.

Due to obsolescence status, equivalent substitute parts from active product lines are necessary to ensure long-term design continuity and supply chain reliability. Active alternatives maintain the core electrical and mechanical specifications while offering improved compliance and availability.

Engineering Selection Recommendations

Direct Amphenol ICC Upgrade Path: The 91596-110LF is the recommended first-choice substitute. It maintains identical mechanical and electrical specifications while transitioning from obsolete to active product status. The primary difference is RoHS compliance, making it suitable for new designs and long-term supply continuity.

Samtec CLT-105 Series Selection: Samtec CLT-105 series connectors provide functionally equivalent substitution with enhanced current rating capability (4.1A per contact vs. 1A). These parts are active products with ROHS3 compliance and multiple packaging options.

For standard applications, CLT-105-02-F-D-BE-A-K-TR offers the most comprehensive feature set with bottom entry configuration, board guide, pick and place capability, and tape & reel packaging for automated assembly. This variant has the highest inventory availability (2977 pieces).

For applications requiring bottom entry configuration without pick and place features, CLT-105-02-F-D-BE provides a simplified alternative.

For applications where bottom entry is not required, CLT-105-02-F-D offers the baseline equivalent with reduced feature complexity.

Compliance Considerations: All substitute parts maintain UL94 V-0 flammability rating and -55°C to 125°C operating temperature range. Samtec parts provide ROHS3 compliance, addressing regulatory requirements for new product designs. The 91596-110LF provides RoHS compliance as an intermediate option within the Amphenol ICC product line.

Frequently Asked Questions (FAQ)

Q: Can CLT-105 series connectors directly replace 91596-110 in existing designs? A: Yes. All CLT-105 variants listed maintain the critical mechanical and electrical parameters: 10 positions, 0.079" pitch, 2-row configuration, surface mount solder termination, and push-pull fastening. The higher current rating (4.1A vs. 1A) provides additional design margin. Insulation height varies slightly (0.083" vs. 0.091"), requiring PCB layout verification for clearance.

Q: What is the difference between bottom entry and standard receptacle configurations? A: Bottom entry connectors (91596-110, CLT-105-02-F-D-BE variants) route mating contacts from the bottom of the connector body, enabling specific PCB routing and stacking configurations. Standard receptacles (CLT-105-02-F-D variants) route contacts from the side. Select bottom entry variants only if the original design requires this specific contact entry orientation.

Q: Does packaging format affect electrical performance? A: No. Tube and tape & reel packaging formats contain identical connector specifications. Packaging selection depends on assembly process requirements. Tape & reel packaging (TR designation) is optimized for automated pick-and-place assembly. Tube packaging is suitable for manual or semi-automated assembly.

Q: What does the board guide feature provide? A: Board guide features (A designation in part numbers) add mechanical alignment assistance during mating, improving connector positioning accuracy on the PCB. This feature is optional and does not affect electrical performance.

Q: Why do Samtec CLT-105 parts have lower contact finish thickness? A: Contact finish thickness (3.00µin vs. 30.0µin) represents different manufacturing specifications. Both thicknesses meet gold plating requirements for the 0.079" pitch connector class and provide equivalent electrical performance and durability for the specified 1A to 4.1A current range.

Q: Is the 91596-110LF a better choice than CLT-105 variants? A: The 91596-110LF maintains identical specifications to the original 91596-110 while providing active product status and RoHS compliance. It is the preferred choice for designs requiring minimal qualification effort. CLT-105 variants are appropriate when higher current capability (4.1A) or specific packaging requirements (tape & reel with pick and place) are beneficial.

Q: What is the inventory status for these substitutes? A: 91596-110LF has 4739 pieces available. CLT-105-02-F-D-BE-A-K-TR has the highest Samtec inventory at 2977 pieces. All listed parts are in active stock.
