78299-104 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 78299-104 is an Amphenol ICC BERGSTIK® II rectangular connector header designed for through-hole, right-angle board-to-board applications. This 4-position, 2-row header with 0.100" (2.54mm) pitch provides press-fit and solder termination options for standard PCB interconnection. The part is currently active in production with 755 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to component availability, supply chain considerations, or design flexibility within the allowed parameter specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 78299-104 is determined by strict equivalence in the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — exact match required
• Number of Positions: 4 — exact match required
• Number of Rows: 2 — exact match required
• Row Spacing - Mating: 0.100" (2.54mm) — exact match required
• Mounting Type: Through Hole, Right Angle — exact match required
• Contact Type: Male Pin — exact match required
• Connector Type: Header (with or without breakaway feature) — functionally compatible
• Style: Board to Board or Board to Cable — compatible for interconnection applications
• Shrouding: Unshrouded — exact match required
• Material Flammability Rating: UL94 V-0 — minimum compliance required

The substitute part 826634-2 (TE Connectivity AMP Connectors AMPMODU Mod II) meets all critical electrical and mechanical parameters for direct substitution in applications requiring a 4-position, 2-row, 2.54mm pitch right-angle header connector.

Parameter Comparison

Engineering Selection Recommendations

The 78299-104 and 826634-2 are electrically and mechanically interchangeable for standard 4-position, 2.54mm pitch right-angle header applications. Selection between these parts should be based on the following criteria:

78299-104 (Amphenol ICC BERGSTIK® II): Select when the original design specification requires the BERGSTIK® II series, when RoHS non-compliance is acceptable for the application, or when inventory availability of this specific series is prioritized.

826634-2 (TE Connectivity AMPMODU Mod II): Select when RoHS compliance is required, when operating temperature specification (-65°C ~ 105°C) must be documented, when current rating specification (5A) is required for design validation, or when TE Connectivity supply chain integration is preferred. The breakaway feature of this connector provides additional design flexibility for modular applications.

Both parts carry UL94 V-0 flammability certification and are suitable for through-hole PCB assembly with right-angle mounting orientation.

Frequently Asked Questions (FAQ)

Q: Can 826634-2 be used as a direct replacement for 78299-104 in existing designs?

A: Yes. Both connectors share identical pitch (0.100" / 2.54mm), position count (4), row configuration (2 rows), and mounting type (through-hole, right-angle). Mechanical and electrical compatibility is confirmed across all critical parameters. The 826634-2 offers additional specifications (operating temperature range and current rating) that may enhance design documentation.

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

A: The primary differences are: (1) Manufacturer and series designation (Amphenol BERGSTIK® II vs. TE Connectivity AMPMODU Mod II); (2) RoHS compliance status (78299-104 is non-compliant; 826634-2 is compliant); (3) Contact material (Phosphor Bronze vs. Brass); (4) Contact finish thickness on mating surface (30.0µin vs. 3.90µin); (5) Insulation material specification (not provided for 78299-104; PBT for 826634-2); (6) Insulation color (Black vs. Green); (7) Operating temperature and current rating specifications provided only for 826634-2.

Q: Are there any dimensional concerns when substituting these parts?

A: Contact length and insulation height dimensions show minor variations. The 826634-2 has a slightly longer mating contact (0.264" vs. 0.230") and insulation height (0.219" vs. 0.190"). These variations are within standard manufacturing tolerances for this connector class and do not affect PCB footprint compatibility or mating performance in standard board-to-board applications.

Q: Which part should be selected for new designs?

A: For new designs, 826634-2 is recommended when RoHS compliance is a requirement or when documented operating temperature and current specifications are needed for design validation. The 78299-104 remains suitable for legacy designs or applications where RoHS non-compliance is acceptable and BERGSTIK® II series continuity is required.

Q: Do these connectors require different PCB footprints?

A: No. Both connectors use identical 0.100" (2.54mm) pitch spacing and 2-row configuration. PCB footprints are interchangeable without modification.
