Amphenol ICC 78299-516 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 78299-516 is a rectangular connector header, right-angle configuration, designed for through-hole mounting in board-to-board applications. This 16-position connector operates at 0.100" (2.54mm) pitch and features male pins with press-fit and solder termination options. The part is currently active in production with 920 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 alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 78299-516 is determined by strict alignment of the following critical parameters:

• Connector type classification (Header)
• Contact type (Male Pin)
• Mating pitch (0.100" / 2.54mm)
• Position count (16 positions)
• Row configuration (2 rows)
• Row spacing (0.100" / 2.54mm)
• Mounting method (Through Hole, Right Angle)
• Board-to-board application compatibility
• Unshrouded design
• Square contact geometry
• UL94 V-0 flammability compliance

The TE Connectivity AMP Connectors part 826634-8 meets all mandatory substitution criteria. This part is classified as a Header with Breakaway capability, accommodating both board-to-board and cable applications, which extends its functional scope while maintaining full compatibility with the original 78299-516 specification for board-to-board use cases.

Parameter Comparison

Engineering Selection Recommendations

Both the 78299-516 and 826634-8 are active production parts with identical core electrical and mechanical specifications for board-to-board applications. Selection between these parts should be based on the following factors:

The 78299-516 (Amphenol ICC BERGSTIK® II) is RoHS non-compliant and should be selected only when legacy system compatibility or specific procurement requirements mandate this status.

The 826634-8 (TE Connectivity AMPMODU Mod II) is RoHS compliant and offers extended functionality through breakaway capability, supporting both board-to-board and cable applications. This part provides greater design flexibility and meets modern regulatory compliance standards. The 826634-8 also provides specified operating temperature range (-65°C ~ 105°C) and current rating (5A), which are not documented for the 78299-516.

Both parts carry UL94 V-0 flammability certification and MSL 1 moisture sensitivity rating. The 826634-8 features a higher inventory level (4304 units versus 920 units), supporting improved supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the 826634-8 directly replace the 78299-516 in existing board-to-board applications?

A: Yes. Both connectors share identical mating pitch (0.100" / 2.54mm), position count (16), row configuration (2 rows), row spacing (0.100" / 2.54mm), mounting type (through-hole right-angle), and contact geometry (square male pins). The 826634-8 is mechanically and electrically compatible for board-to-board use.

Q: What are the differences in contact dimensions?

A: The 826634-8 has slightly longer mating contact length (0.264" versus 0.230") and post length (0.126" versus 0.120"), with correspondingly higher insulation height (0.219" versus 0.190"). These dimensional variations fall within acceptable tolerance ranges for standard 2.54mm pitch connector applications but should be verified against specific PCB layout and mating connector specifications.

Q: Does the RoHS compliance difference affect substitution eligibility?

A: RoHS compliance status does not affect electrical or mechanical substitution eligibility. The 78299-516 is RoHS non-compliant while the 826634-8 is RoHS compliant. Selection depends on regulatory requirements applicable to the end application and system design phase.

Q: What is the significance of the breakaway feature on the 826634-8?

A: The breakaway feature on the 826634-8 allows individual connector positions to be separated for custom configurations. This feature does not impact board-to-board compatibility and provides additional design flexibility for applications requiring partial connector use.

Q: Are there material differences between these connectors?

A: Yes. The 78299-516 uses phosphor bronze contacts, while the 826634-8 uses brass contacts. Both materials are standard for 2.54mm pitch connectors. The 826634-8 specifies polybutylene terephthalate (PBT) insulation material, while the 78299-516 insulation material is not documented. Both meet UL94 V-0 flammability requirements.

Q: Which part should be selected for new designs?

A: The 826634-8 is recommended for new designs due to RoHS compliance, documented operating temperature range (-65°C ~ 105°C), specified current rating (5A), and higher inventory availability. The 78299-516 should be reserved for legacy system maintenance or when specific procurement constraints require non-compliant components.
