Amphenol ICC 91596-112LF Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 91596-112LF is a 12-position rectangular receptacle connector with 0.079" (2.00mm) pitch, designed for surface mount applications in board-to-board or cable interconnect configurations. This connector features bottom entry design, gold-plated mating contacts, and operates across the industrial temperature range of -55°C to 125°C. The part is Active status and RoHS Compliant, with 1029 units currently in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design flexibility permits selection from qualified alternatives that meet identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the 91596-112LF are qualified based on the following critical parameters that must remain constant:

12-position configuration with 2-row layout
0.079" (2.00mm) mating pitch and row spacing
Surface mount solder termination
Female socket contact type
Push-pull fastening mechanism
Gold-plated mating contacts
Operating temperature range -55°C to 125°C
UL94 V-0 flammability rating
Bottom entry connector design (for direct mechanical substitution)

All substitute parts listed are manufactured by Samtec Inc. under the CLT series. Substitution is permitted across different packaging formats (Tube vs. Tape & Reel), contact finish post materials (Tin vs. Gold), contact finish thicknesses, insulation materials (Plastic vs. Liquid Crystal Polymer), and optional features (Board Guide, Pick and Place). These variations do not affect electrical or mechanical compatibility when mating with corresponding plug connectors.

Engineering Selection Recommendations

Primary Substitutes (Bottom Entry Configuration):

CLT-106-02-F-D-BE, CLT-106-02-F-D-BE-A, and CLT-106-02-G-D-BE are direct mechanical and electrical substitutes for the 91596-112LF. These parts maintain identical connector type (Receptacle, Bottom Entry), position count, pitch, row spacing, contact configuration, and operating temperature range. All are ROHS3 Compliant and carry UL94 V-0 flammability certification. Selection among these three depends on packaging preference (Tube) and optional features (Board Guide available on CLT-106-02-F-D-BE-A and CLT-106-02-G-D-BE).

Tape & Reel Alternative:

CLT-106-02-F-D-BE-K-TR provides identical electrical and mechanical specifications in Tape & Reel packaging format, suitable for automated assembly processes. This variant includes Pick and Place features and maintains all compliance certifications.

Standard Entry Alternative:

CLT-106-02-F-D is electrically and mechanically compatible but features standard entry design rather than bottom entry. This part is suitable only when mechanical constraints permit standard entry configuration.

Gold Post Finish Variants:

CLT-106-02-G-D and CLT-106-02-G-D-A feature gold plating on both mating and post contacts, compared to tin post finish on F-series variants. These are functionally equivalent when gold post finish is required by design specification.

All Samtec CLT-106 substitutes exceed the 1A current rating of the 91596-112LF, providing 4.1A per contact capacity. This represents a design margin improvement without affecting compatibility.

Frequently Asked Questions (FAQ)

Q: Can CLT-106-02-F-D (standard entry) be used in place of 91596-112LF (bottom entry)?

A: CLT-106-02-F-D is electrically compatible but differs in mechanical entry configuration. Use only if the PCB layout and mating connector accommodate standard entry design. Bottom entry variants (CLT-106-02-F-D-BE, CLT-106-02-F-D-BE-A) provide direct mechanical substitution.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging is suitable for manual assembly and small-volume production. Tape & Reel (TR) packaging is designed for automated pick-and-place assembly equipment. CLT-106-02-F-D-BE-K-TR provides the same electrical and mechanical specifications in Tape & Reel format.

Q: Are the Samtec CLT-106 series parts compatible with Amphenol ICC Minitek 2.00mm plug connectors?

A: Compatibility depends on the specific plug connector model. Both receptacle and plug must share identical pitch (0.079"), row spacing (0.079"), position count (12), and contact configuration. Verify mating connector specifications before substitution.

Q: What is the significance of the higher current rating (4.1A vs. 1A) on Samtec substitutes?

A: The Samtec CLT-106 series is rated for 4.1A per contact, exceeding the 91596-112LF specification of 1A. This represents a design margin improvement and does not affect compatibility. The connector can be used in applications requiring up to 4.1A per contact without derating.

Q: Can I substitute between F-series (tin post) and G-series (gold post) variants?

A: Yes, F-series and G-series variants are electrically and mechanically interchangeable. Selection depends on whether gold post finish is required by design specification or environmental conditions. Both maintain identical mating contact gold plating and operating characteristics.

Q: Are all listed substitutes RoHS compliant?

A: Yes. The 91596-112LF is RoHS Compliant. All Samtec CLT-106 substitutes listed are ROHS3 Compliant, meeting current RoHS Directive requirements.

Q: What does "Board Guide" feature mean on CLT-106-02-F-D-BE-A?

A: Board Guide is an optional mechanical feature that aids in connector alignment during assembly. Its presence does not affect electrical performance or compatibility with standard mating connectors.
