Amphenol ICC 89882-403 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 89882-403 is a 3-position receptacle connector with 0.100" (2.54mm) pitch, designed for through-hole, right-angle board-to-board applications. This connector features tin-lead contact finish and is part of the Dubox™ series. The part is currently obsolete, making identification of suitable substitutes necessary for ongoing system support and new designs requiring compatible interconnect solutions.

Key Parameters

Substitute Part Grouping Explanation

The 89882-403LF qualifies as a direct substitute based on the following critical parameters:

• Connector Type & Position Count: Both are 3-position receptacles
• Pitch Specification: Both maintain 0.100" (2.54mm) mating pitch
• Mounting Configuration: Both are through-hole, right-angle board-to-board connectors
• Contact Geometry: Both feature female socket contacts with square shape and phosphor bronze material
• Insulation Properties: Both use thermoplastic, glass-filled insulation with UL94 V-0 rating
• Mechanical Dimensions: Insulation height (0.130"), contact length (0.114"), and row configuration are identical
• Series Compatibility: Both belong to the Dubox™ series

The primary difference is the contact finish specification: the 89882-403 uses tin-lead finish (196.9µin / 5.00µm), while the 89882-403LF uses tin finish (78.7µin / 2.00µm). This distinction reflects regulatory compliance evolution rather than functional incompatibility.

Parameter Comparison

Engineering Selection Recommendations

The 89882-403LF is the active production equivalent of the obsolete 89882-403. Selection between these parts depends on regulatory and compliance requirements:

Use 89882-403LF for:

• New designs and production builds
• Applications requiring RoHS compliance
• Systems subject to REACH regulations
• Long-term supply chain continuity

Use 89882-403 for:

• Legacy system repairs where original tin-lead finish is specified
• Applications explicitly exempted from RoHS requirements
• Existing inventory management

Both connectors maintain identical mechanical and electrical interface specifications, ensuring direct interchangeability in board-to-board applications with 0.100" pitch mating requirements.

Frequently Asked Questions (FAQ)

Q: Are the 89882-403 and 89882-403LF mechanically interchangeable?

A: Yes. Both connectors share identical mounting type (through-hole, right-angle), position count (3), pitch (0.100"), insulation dimensions, and contact geometry. They are mechanically and electrically interchangeable.

Q: What is the difference between tin-lead and tin contact finishes?

A: The 89882-403 uses tin-lead finish (5.00µm thickness), while the 89882-403LF uses tin finish (2.00µm thickness). This reflects the transition from lead-containing to lead-free manufacturing standards. Both finishes provide equivalent electrical performance and solder joint reliability.

Q: Why is the 89882-403 marked as obsolete?

A: The part has been superseded by the 89882-403LF, which meets current RoHS compliance requirements. Amphenol ICC has transitioned production to the lead-free variant.

Q: Can I use the 89882-403LF as a direct replacement in existing designs?

A: Yes, the 89882-403LF is a direct functional replacement. Verify that your application or regulatory framework does not explicitly require the tin-lead finish variant.

Q: What is the packaging difference?

A: The 89882-403 is supplied in standard packaging, while the 89882-403LF is supplied in bulk packaging. This does not affect connector performance or compatibility.

Q: Are there any soldering process differences between these parts?

A: Both parts use solder termination and are compatible with standard PCB assembly processes. The tin-lead finish of the 89882-403 may have different thermal characteristics compared to the tin finish of the 89882-403LF, but both are suitable for conventional reflow and wave soldering.
