Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Amphenol ICC 78299-540 is determined by the following critical parameters:

• Connector Type: Header configuration
• Contact Type: Male Pin
• Pitch - Mating: 0.100" (2.54mm) — exact match required
• Number of Positions: 40 — 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
• Style: Board to Board or Board to Board/Cable compatible
• Shrouding: Unshrouded
• Contact Shape: Square
• Material Flammability Rating: UL94 V-0 — minimum requirement

The TE Connectivity AMP Connectors part 2-826634-0 meets all critical substitution criteria. This part maintains identical mating pitch, position count, row configuration, and mounting orientation. Both connectors feature unshrouded, square-contact male pin headers with UL94 V-0 flammability ratings suitable for through-hole, right-angle board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 2-826634-0 is a qualified substitute for the Amphenol ICC 78299-540 based on matching critical electrical and mechanical parameters. Both connectors maintain identical mating pitch (2.54mm), position count (40), row configuration (2 rows), and right-angle through-hole mounting orientation.

Key differentiation factors:

• RoHS Compliance: The TE Connectivity part is ROHS3 compliant, while the Amphenol ICC part is RoHS non-compliant. Selection should align with regulatory requirements for the target application.
• Contact Material: Amphenol ICC uses phosphor bronze; TE Connectivity uses brass. Both materials are suitable for standard board-to-board applications.
• Insulation Material: TE Connectivity specifies polybutylene terephthalate (PBT); Amphenol ICC does not specify insulation material. PBT provides documented thermal and chemical resistance.
• Operating Temperature: TE Connectivity specifies -65°C ~ 105°C operating range; Amphenol ICC does not specify. Applications requiring defined temperature performance should reference the TE Connectivity specification.
• Current Rating: TE Connectivity specifies 5A; Amphenol ICC does not specify. Applications with defined current requirements should reference the TE Connectivity specification.
• Inventory Availability: TE Connectivity 2-826634-0 has 2820 units in stock compared to 856 units for the Amphenol ICC part.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 2-826634-0 be used as a direct replacement for the Amphenol ICC 78299-540?

A: Yes, the TE Connectivity 2-826634-0 qualifies as a substitute. Both connectors share identical mating pitch (2.54mm), position count (40), row spacing (2 rows at 0.100" spacing), and right-angle through-hole mounting configuration. Mechanical and electrical compatibility is maintained for board-to-board applications.

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

A: Primary differences include contact material (phosphor bronze vs. brass), insulation material specification (unspecified vs. PBT), RoHS compliance status (non-compliant vs. ROHS3 compliant), and documented operating temperature range (unspecified vs. -65°C ~ 105°C). Both maintain UL94 V-0 flammability ratings and identical pitch/position configurations.

Q: Does the TE Connectivity part support cable applications?

A: The TE Connectivity 2-826634-0 is classified as "Header, Breakaway" with "Board to Board or Cable" style capability. The Amphenol ICC 78299-540 is specified for "Board to Board" style only. If cable connectivity is required, the TE Connectivity part provides additional application flexibility.

Q: Are there any compliance considerations when substituting?

A: Yes. The TE Connectivity 2-826634-0 is ROHS3 compliant, while the Amphenol ICC 78299-540 is RoHS non-compliant. Applications subject to RoHS regulations should use the TE Connectivity part. Both parts have MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What is the impact of different contact materials?

A: The Amphenol ICC part uses phosphor bronze contacts; the TE Connectivity part uses brass contacts. Both materials are standard for rectangular connectors in board-to-board applications. Contact material selection does not affect mechanical compatibility or mating performance for standard signal and power distribution applications.

Q: How do the insulation materials compare?

A: The TE Connectivity part specifies polybutylene terephthalate (PBT) insulation with documented thermal and chemical resistance. The Amphenol ICC part does not specify insulation material. PBT is a standard engineering thermoplastic suitable for industrial and commercial applications with defined performance characteristics.
