Amphenol ICC 78299-508 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 78299-508 is a rectangular connector header classified as BERGSTIK® II series, designed for through-hole, right-angle board-to-board applications. This 8-position connector operates at 0.100" (2.54mm) pitch and features male pin contacts with press-fit and solder termination options. The part is currently active in production with 735 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part becomes unavailable or when design requirements permit alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 78299-508 is determined by strict alignment of the following critical parameters:

• Connector Type: Header configuration
• Contact Type: Male Pin contacts
• Pitch - Mating: 0.100" (2.54mm) spacing
• Number of Positions: 8-position configuration
• Number of Rows: 2-row arrangement
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole, Right Angle orientation
• Style: Board to Board connectivity
• Shrouding: Unshrouded design
• Contact Shape: Square profile
• Material Flammability Rating: UL94 V-0 compliance

The TE Connectivity AMP Connectors 826634-4 meets all critical substitution criteria. This part maintains identical mating pitch, position count, row configuration, mounting orientation, and flammability rating. Variations in contact length, insulation height, contact material composition, and finish specifications remain within acceptable tolerances for equivalent board-to-board header applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 78299-508 and 826634-4 maintain active product status and are suitable for new designs and production applications. The 826634-4 offers ROHS3 compliance, whereas the 78299-508 is RoHS non-compliant. Selection between these parts should account for regulatory requirements in the target application and end-market jurisdiction. Both connectors carry UL94 V-0 flammability certification and MSL 1 moisture sensitivity rating, indicating equivalent environmental performance characteristics. The 826634-4 provides additional flexibility through breakaway connector capability and specified operating temperature range (-65°C ~ 105°C) and current rating (5A), whereas the 78299-508 does not specify these parameters. For applications requiring RoHS compliance or specified thermal and electrical performance data, the 826634-4 is the preferred selection. For applications without RoHS requirements and where the 78299-508 specifications are sufficient, either part is functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can the 826634-4 directly replace the 78299-508 in existing designs?

A: Yes. Both connectors share identical mating pitch (0.100"), position count (8), row configuration (2), mounting type (through-hole right-angle), and contact geometry (square male pins). The 826634-4 features slightly longer contact lengths and greater insulation height, which remain compatible with standard PCB footprints designed for 2.54mm pitch headers.

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

A: Primary differences include contact material (Phosphor Bronze vs. Brass), contact finish composition, insulation material specification, RoHS compliance status, and specified operating parameters. The 826634-4 provides documented operating temperature range and current rating, while the 78299-508 does not specify these values.

Q: Are there packaging or inventory considerations for substitution?

A: The 78299-508 is available in bulk packaging with 735 units in stock. The 826634-4 is also available in bulk packaging with 7,547 units in stock, providing greater availability for high-volume applications.

Q: Does the difference in contact material affect electrical performance?

A: Both Phosphor Bronze and Brass contacts with gold plating provide equivalent electrical conductivity and contact resistance for standard board-to-board header applications. Material selection does not impact functional compatibility.

Q: Is the breakaway feature of the 826634-4 relevant for substitution?

A: The breakaway capability of the 826634-4 is an additional feature that does not affect compatibility with applications designed for the 78299-508. This feature provides design flexibility for applications requiring individual position separation.

Q: What compliance certifications apply to both parts?

A: Both connectors carry UL94 V-0 flammability certification and MSL 1 moisture sensitivity rating. The 826634-4 additionally carries ROHS3 compliance certification, while the 78299-508 is RoHS non-compliant.
