Amphenol ICC 91036-120 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 91036-120 is a rectangular connector header designed for surface mount applications with 40 positions arranged in 2 rows at 0.050" (1.27mm) pitch. This component belongs to the Rib-Cage™ III series and features shrouded 4-wall construction with push-pull fastening. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Amphenol ICC 91036-120 is determined by strict alignment of the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Position count (40 positions)
• Row configuration (2 rows)
• Mating pitch (0.050" / 1.27mm)
• Row spacing (0.050" / 1.27mm)
• Mounting method (Surface Mount)
• Board-to-board style
• Shrouding configuration (Shrouded - 4 Wall)
• Fastening mechanism (Push-Pull)
• Termination method (Solder)
• Flammability compliance (UL94 V-0)

The TE Connectivity AMP Connectors part number 5-104693-4 meets all these core electrical and mechanical requirements, establishing it as a direct functional equivalent despite differences in contact geometry, insulation material, and temperature operating range.

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 5-104693-4 is the designated substitute for the obsolete Amphenol ICC 91036-120. Selection of this alternative is supported by the following factors:

• Active product status ensures ongoing availability and manufacturing support
• ROHS3 compliance addresses regulatory requirements not met by the original part
• Identical mating pitch, row configuration, and position count guarantee mechanical and electrical compatibility
• Matching flammability rating (UL94 V-0) maintains safety compliance
• Equivalent contact finish thickness on mating surfaces preserves signal integrity
• Mated stacking height differential of 0.02mm is negligible for board-to-board applications
• Operating temperature range of -65°C ~ 105°C covers the majority of industrial and commercial applications; designs requiring the full -55°C ~ 130°C range of the original part require thermal analysis

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5-104693-4 be used as a direct replacement for the Amphenol ICC 91036-120?

A: Yes. Both connectors share identical mating pitch (0.050" / 1.27mm), position count (40), row configuration (2 rows), mounting type (surface mount), shrouding (4-wall), and fastening mechanism (push-pull). The connectors are mechanically and electrically compatible for board-to-board applications.

Q: What are the differences between these two connectors?

A: The primary differences are contact shape (square vs. circular), insulation material (thermoplastic glass-filled vs. liquid crystal polymer), operating temperature range (-55°C ~ 130°C vs. -65°C ~ 105°C), and RoHS compliance status. The TE Connectivity part is ROHS3 compliant while the Amphenol part is not.

Q: Does the change in contact shape from square to circular affect compatibility?

A: No. Both contact shapes are designed for the same 0.050" (1.27mm) pitch and deliver equivalent electrical performance. The circular contact geometry of the TE Connectivity part is a design variation that does not impact mating or signal integrity.

Q: Are there packaging differences between these parts?

A: The TE Connectivity 5-104693-4 is supplied in tube packaging. Verify packaging requirements for your production process.

Q: What is the temperature operating range limitation?

A: The TE Connectivity substitute operates from -65°C ~ 105°C, compared to the original -55°C ~ 130°C range. Applications requiring operation above 105°C or below -65°C require thermal performance verification.

Q: Is the mated stacking height difference significant?

A: The difference of 0.02mm (9.93mm vs. 9.91mm) is within standard manufacturing tolerances and does not affect board-to-board spacing or mechanical fit.
