Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 78299-408 is determined by strict equivalence across the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 8
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole, Right Angle
• Contact Type: Male Pin
• Connector Type: Header
• Shrouding: Unshrouded
• Contact Shape: Square
• Material Flammability Rating: UL94 V-0

The TE Connectivity AMP Connectors part number 826634-4 meets all critical substitution criteria. Both parts maintain identical mating pitch, position count, row configuration, and mounting orientation. Both are unshrouded headers with square male pins and UL94 V-0 flammability ratings, ensuring mechanical and electrical compatibility in board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 78299-408 and 826634-4 are active production parts with identical critical mating parameters, ensuring mechanical and electrical interchangeability in board-to-board header applications. Selection between these parts should be based on the following factors:

The 78299-408 (Amphenol ICC BERGSTIK® II) is RoHS non-compliant and offers press-fit termination capability in addition to solder termination. This part is suitable for applications where RoHS compliance is not required and press-fit assembly is advantageous.

The 826634-4 (TE Connectivity AMPMODU Mod II) is ROHS3 compliant and provides higher inventory availability (7547 units versus 1056 units). This part features gold-plated mating contacts, brass contact material, and specified operating temperature range (-65°C ~ 105°C) with 5A current rating. The breakaway connector option provides additional design flexibility. This part is suitable for applications requiring RoHS3 compliance and extended environmental specifications.

Both parts maintain UL94 V-0 flammability ratings and MSL 1 moisture sensitivity levels. Minor dimensional variations exist in contact length and insulation height; these differences do not affect mechanical fit in standard 2.54mm pitch header applications.

Frequently Asked Questions (FAQ)

Q: Are the 78299-408 and 826634-4 mechanically interchangeable?

A: Yes. Both parts share identical mating pitch (0.100" / 2.54mm), position count (8), row configuration (2 rows), and right-angle through-hole mounting. The minor differences in contact length (0.230" versus 0.264") and insulation height (0.190" versus 0.219") do not prevent mechanical substitution in standard board-to-board applications.

Q: What is the primary difference between these two parts?

A: The 826634-4 is ROHS3 compliant with specified operating temperature (-65°C ~ 105°C) and current rating (5A), while the 78299-408 is RoHS non-compliant with unspecified environmental ratings. The 78299-408 supports both press-fit and solder termination, whereas the 826634-4 supports solder termination only. Contact finish differs: tin on the 78299-408 versus gold on the 826634-4.

Q: Can I use the 826634-4 as a direct replacement for the 78299-408?

A: Direct substitution is possible from a mechanical and electrical standpoint. However, if your application requires RoHS non-compliance or press-fit assembly capability, the 78299-408 is the appropriate choice. If RoHS3 compliance is required, the 826634-4 is the suitable option.

Q: What are the termination differences?

A: The 78299-408 supports both press-fit and solder termination, providing assembly flexibility. The 826634-4 supports solder termination only. Verify your assembly process requirements before substitution.

Q: Does the contact finish difference affect compatibility?

A: Both tin and gold finishes are standard for 2.54mm pitch header applications. Gold plating on the 826634-4 provides enhanced corrosion resistance and contact reliability. Tin plating on the 78299-408 is suitable for standard industrial applications. Contact finish does not affect mechanical fit or basic electrical function.

Q: Are there inventory considerations?

A: The 826634-4 has significantly higher inventory availability (7547 units) compared to the 78299-408 (1056 units). If supply continuity is a concern, the 826634-4 may be preferable.
