Amphenol ICC 78299-404 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 78299-404 is a through-hole, right-angle rectangular connector header with 4 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This BERGSTIK® II series connector is designed for board-to-board applications requiring press-fit and solder termination with push-pull fastening. The part is currently active in production with 811 units in stock. Substitute parts are identified when inventory constraints, lead time requirements, or specific application needs necessitate alternative sourcing while maintaining functional compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the Amphenol ICC 78299-404 is determined by strict alignment of the following critical parameters:

Connector Type & Contact Configuration: Header with male pins
Position Count & Row Arrangement: 4 positions in 2 rows
Pitch Specification: 0.100" (2.54mm) mating pitch and row spacing
Mounting & Orientation: Through-hole, right-angle mounting
Fastening Mechanism: Push-pull fastening
Shrouding Status: Unshrouded design
Flammability Compliance: UL94 V-0 rating

The TE Connectivity AMP Connectors part number 826634-2 qualifies as a direct substitute based on matching all critical parameters. Both connectors share identical pitch, position count, row configuration, mounting type, and fastening mechanism. Functional interchangeability is established through these core electrical and mechanical specifications.

Engineering Selection Recommendations

Both the Amphenol ICC 78299-404 and TE Connectivity 826634-2 are active production parts with unlimited moisture sensitivity tolerance. Selection between these connectors should be based on regulatory and compliance requirements specific to the application.

The TE Connectivity 826634-2 is RoHS compliant, making it the appropriate choice for applications subject to RoHS directives or customer specifications requiring RoHS certification. The Amphenol ICC 78299-404 is RoHS non-compliant and should be selected only when RoHS compliance is not a requirement.

Both connectors meet UL94 V-0 flammability standards. The TE Connectivity part provides documented operating temperature range (-65°C ~ 105°C) and current rating (5A), while the Amphenol ICC part does not specify these parameters in the available data.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 826634-2 be used as a direct replacement for the Amphenol ICC 78299-404?

A: Yes, the TE Connectivity 826634-2 qualifies as a functional substitute. Both connectors share identical pitch (0.100"), position count (4), row configuration (2 rows), mounting type (through-hole right-angle), and fastening mechanism (push-pull). Physical and electrical interchangeability is established through these core specifications.

Q: What are the key differences between these two connectors?

A: The primary differences are contact finish (tin vs. gold), contact material (phosphor bronze vs. brass), insulation material specification (not specified vs. PBT), and RoHS compliance status (non-compliant vs. compliant). The TE Connectivity part also provides documented operating temperature and current rating specifications.

Q: Which connector should I select for a new design?

A: Selection depends on regulatory requirements. If RoHS compliance is mandatory, select the TE Connectivity 826634-2. If RoHS compliance is not required and tin-plated phosphor bronze contacts are preferred, the Amphenol ICC 78299-404 is suitable. Both parts are active in production with adequate inventory.

Q: Are there dimensional compatibility concerns between these connectors?

A: Contact length and insulation height differ slightly between the two parts. The TE Connectivity 826634-2 has longer mating contacts (0.264" vs. 0.230") and greater insulation height (0.219" vs. 0.190"). These dimensional variations should be evaluated against specific PCB layout and mating connector specifications to ensure proper engagement and clearance.

Q: What is the moisture sensitivity level for both connectors?

A: Both connectors are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
