Amphenol ICC 78299-504 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 78299-504 is a through-hole, right-angle rectangular connector header with 4 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This connector is part of the BERGSTIK® II series and is designed for board-to-board applications requiring press-fit and solder termination. The part maintains active product status with 779 units in current inventory. 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.

Substitute Part Grouping Explanation

Substitution eligibility for the Amphenol ICC 78299-504 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 4
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole, Right Angle
• Contact Shape: Square
• Shrouding: Unshrouded
• Style: Board to Board or Board to Board/Cable compatible

Allowable Variations:

• Contact material (Phosphor Bronze or Brass)
• Contact finish composition and thickness
• Insulation material and color
• Termination method (Press-Fit, Solder, or combined)
• Operating temperature range
• Current rating specifications
• RoHS compliance status

The TE Connectivity AMP Connectors 826634-2 meets all mandatory matching parameters and qualifies as a direct substitute for the Amphenol ICC 78299-504.

Parameter Comparison

Engineering Selection Recommendations

Primary Part - Amphenol ICC 78299-504:

• Active product status with established supply chain
• RoHS non-compliant designation requires verification against application regulatory requirements
• UL94 V-0 flammability rating meets safety standards
• MSL 1 rating indicates no moisture sensitivity constraints

Substitute Part - TE Connectivity 826634-2:

• Active product status with comparable inventory availability
• RoHS Compliant designation provides regulatory advantage for applications subject to RoHS requirements
• UL94 V-0 flammability rating maintains safety standard equivalence
• MSL 1 rating maintains moisture sensitivity equivalence
• Specified operating temperature range (-65°C ~ 105°C) and current rating (5A) provide defined performance envelope
• Breakaway connector feature offers additional design flexibility

Selection between these parts depends on regulatory compliance requirements and application-specific performance specifications. Both parts satisfy the core electrical and mechanical interface requirements for 4-position, 2-row, 2.54mm pitch through-hole right-angle header applications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 826634-2 be used as a direct replacement for the Amphenol ICC 78299-504?

A: Yes. Both connectors share identical pitch (0.100"), position count (4), row configuration (2 rows), row spacing (0.100"), contact type (male pin), mounting style (through-hole right-angle), and contact shape (square). The mechanical and electrical interface parameters are equivalent.

Q: What are the differences in contact dimensions between these parts?

A: The TE Connectivity 826634-2 has slightly longer mating contact length (0.264" vs. 0.230") and post length (0.126" vs. 0.120"), with correspondingly greater insulation height (0.219" vs. 0.190"). These dimensional variations remain within typical tolerance ranges for 2.54mm pitch header connectors and do not prevent functional interchangeability in standard board-to-board applications.

Q: Does the RoHS compliance difference affect substitution eligibility?

A: RoHS compliance status is a regulatory and supply-chain consideration rather than a functional compatibility factor. The Amphenol ICC 78299-504 is RoHS non-compliant, while the TE Connectivity 826634-2 is RoHS Compliant. Selection depends on whether the application or end-market requires RoHS compliance. Both parts meet UL94 V-0 flammability requirements.

Q: Are the contact materials interchangeable?

A: The Amphenol ICC 78299-504 uses Phosphor Bronze contacts, while the TE Connectivity 826634-2 uses Brass contacts. Both materials are standard for connector applications and provide equivalent electrical conductivity and durability for 2.54mm pitch header interfaces. Contact finish specifications (gold plating) ensure reliable mating performance in both cases.

Q: What is the significance of the "Breakaway" feature on the TE Connectivity part?

A: The TE Connectivity 826634-2 is designated as a "Header, Breakaway" connector, indicating that individual positions can be separated if required. The Amphenol ICC 78299-504 does not specify this feature. This difference does not affect standard board-to-board applications where the full 4-position connector is used intact.

Q: Are there any termination method differences to consider?

A: The Amphenol ICC 78299-504 supports both Press-Fit and Solder termination. The TE Connectivity 826634-2 specifies Solder termination only. If press-fit termination is required for the application, the Amphenol ICC part is the appropriate choice. For solder-only applications, both parts are functionally equivalent.
