Amphenol ICC 89891-316 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 89891-316 is a 32-position receptacle connector in the Dubox™ series, designed for board-to-board applications with 0.100" (2.54mm) pitch spacing. This connector features bottom or top entry configuration with through-hole solder termination and gold-plated mating contacts. The part is currently listed as obsolete, making identification of suitable substitutes essential for ongoing system support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

The 89891-316LF serves as a direct substitute for the 89891-316 based on the following critical parameters that determine functional and mechanical compatibility:

• Connector Type & Configuration: Both are receptacle connectors with bottom or top entry capability
• Position Count & Pitch: Identical 32-position layout with 0.100" (2.54mm) mating pitch and row spacing
• Mounting & Termination: Both use through-hole solder termination
• Contact System: Identical female socket contacts with gold mating finish and tin post finish
• Insulation Properties: Matching thermoplastic glass-filled insulation with UL94 V-0 flammability rating
• Physical Dimensions: Equivalent insulation height (0.335"), contact length (0.114"), and contact geometry

The primary distinction between these parts is product status and compliance certification, not electrical or mechanical function.

Parameter Comparison

Engineering Selection Recommendations

The 89891-316LF is the appropriate substitute for the obsolete 89891-316 in new designs and ongoing procurement. Both connectors are electrically and mechanically identical across all functional parameters. The 89891-316LF offers the advantage of active product status, ensuring continued availability and manufacturer support.

For applications requiring RoHS compliance, the 89891-316LF is the mandated selection. The 89891-316 does not meet RoHS requirements and should not be specified for new applications subject to RoHS regulations.

The 89891-316LF is supplied in tube packaging, whereas the 89891-316 was supplied in bulk packaging. This packaging difference does not affect connector performance or compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 89891-316LF be used as a direct replacement for the 89891-316?

A: Yes. The connectors are functionally and mechanically identical. All electrical parameters, contact geometry, pitch spacing, mounting configuration, and insulation properties are equivalent. The primary difference is product status and compliance certification.

Q: What is the significance of the "LF" designation in the 89891-316LF part number?

A: The "LF" suffix indicates Lead-Free construction, which aligns with RoHS compliance requirements. This designation reflects the material composition of the connector, specifically the elimination of lead from solder and plating materials.

Q: Are there any compatibility concerns when substituting the 89891-316LF for the 89891-316?

A: No compatibility concerns exist. Both connectors feature identical 32-position, 0.100" pitch receptacle configurations with matching contact systems, insulation materials, and physical dimensions. They are interchangeable at the board level.

Q: Does the packaging difference (bulk vs. tube) affect connector selection?

A: No. Packaging is a logistics consideration only and does not impact electrical or mechanical performance. The connector itself is identical regardless of packaging format.

Q: Which part should be specified for new designs?

A: The 89891-316LF should be specified for all new designs. It is the active product with current manufacturer support and meets modern compliance standards including RoHS requirements.
