Amphenol ICC 91486-541 Rectangular Connector Plug Housing - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 91486-541 is an 8-position rectangular connector plug housing from the LATCH-N-LOK™ series, designed for free-hanging inline applications with crimp contact termination and latch lock fastening. This component is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations. The part features a 0.100" (2.54mm) pitch configuration with 2-row arrangement and polycarbonate insulation material suitable for operating temperatures between -40°C and 85°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 91486-541 is determined by strict alignment with the following critical parameters:

• Connector Type & Contact Configuration: Plug housing with female socket contacts
• Position Count & Pitch: 8 positions at 0.100" (2.54mm) pitch
• Row Configuration: 2-row arrangement with 0.100" (2.54mm) row spacing
• Termination Method: Crimp contact termination
• Fastening Mechanism: Latch lock fastening type
• Mounting Style: Free hanging inline configuration
• Contact Compatibility: Contacts not included; housing must accept equivalent crimp contacts

The TE Connectivity AMP Connectors part 936233-1 qualifies as a parametric equivalent based on matching all critical mechanical and electrical interface parameters. Differences in insulation material (PBT vs. PC), color, and operating temperature ceiling do not preclude functional substitution when environmental specifications are within the substitute's rated range.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 936233-1 is the identified parametric equivalent for the obsolete Amphenol ICC 91486-541. Selection between these parts should be based on the following engineering criteria:

For New Designs or Compliance-Driven Applications: The 936233-1 is the preferred choice. It maintains active product status, ensuring long-term availability and supply chain stability. The part achieves ROHS3 compliance, meeting modern regulatory requirements for new equipment designs and procurement specifications.

For Legacy System Maintenance: The 91486-541 remains suitable for direct replacement in existing installations where the original part specifications are required and RoHS non-compliance does not conflict with system-level requirements.

Temperature Consideration: Applications requiring sustained operation at temperatures between 80°C and 85°C must retain the original 91486-541 or identify alternative solutions, as the 936233-1 is rated to 80°C maximum.

Material Compatibility: Both parts employ different insulation materials (PC vs. PBT). In applications with specific chemical exposure or mechanical stress requirements tied to polycarbonate properties, material compatibility must be independently evaluated.

Frequently Asked Questions (FAQ)

Q: Can the 936233-1 directly replace the 91486-541 in existing assemblies?

A: Yes, for applications operating within -40°C to 80°C. The 936233-1 matches all critical mechanical and electrical interface parameters: 8-position, 2-row configuration at 0.100" pitch, crimp termination, and latch lock fastening. Existing crimp contacts designed for the 91486-541 are compatible with the 936233-1 housing.

Q: What is the significance of the different insulation materials?

A: The 91486-541 uses polycarbonate (PC) insulation; the 936233-1 uses polybutylene terephthalate (PBT). Both materials are suitable for standard industrial applications. PBT offers superior chemical resistance in certain environments, while PC provides better impact resistance at low temperatures. Material selection should align with the specific chemical and mechanical environment of the application.

Q: Why is the 91486-541 listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Amphenol ICC. The 936233-1 from TE Connectivity provides functional continuity for applications requiring this connector form factor and pin configuration.

Q: Are contacts included with either housing?

A: No. Both the 91486-541 and 936233-1 are supplied as housings only. Crimp contacts must be sourced separately and must be compatible with the 0.100" (2.54mm) pitch and crimp termination specification.

Q: What is the difference in operating temperature ranges?

A: The 91486-541 operates from -40°C to 85°C; the 936233-1 operates from -40°C to 80°C. For applications requiring the full 85°C upper limit, the original part must be retained or alternative solutions identified.

Q: Does RoHS compliance affect substitution decisions?

A: RoHS compliance is a regulatory and procurement consideration, not a functional one. The 936233-1's ROHS3 compliance makes it suitable for new designs and systems subject to RoHS regulations. Legacy systems using the non-compliant 91486-541 may continue operation without functional impact, but new procurements should prioritize the compliant alternative.
