Amphenol ICC 78299-606 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 78299-606 is a rectangular connector header featuring a right-angle, through-hole configuration with 6 positions at 2.54mm pitch. This BERGSTIK® II series component is designed for board-to-board applications with press-fit and solder termination options. The part maintains Active product status with 886 units in current inventory.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct replacement in applications where the core functional requirements remain constant.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment of the following parameters:

• Connector type classification (Header)
• Contact type and gender (Male Pin)
• Mating pitch and position count (0.100" / 2.54mm, 6 positions)
• Row configuration (2 rows at 0.100" spacing)
• Mounting orientation (Through Hole, Right Angle)
• Shrouding status (Unshrouded)
• Contact geometry (Square shape)
• Flammability compliance (UL94 V-0)
• Fastening mechanism (Push-Pull)

The three identified substitutes—TE Connectivity 826634-3, Samtec HTSW-103-08-S-D-RA, and Samtec HTSW-103-09-F-D-RA—satisfy these core parameters. Variations in contact length, insulation material, and operating temperature ranges reflect design differences within the acceptable substitution envelope.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain Active product status and satisfy the core electrical and mechanical substitution criteria. Selection should account for the following compliance and availability factors:

TE Connectivity 826634-3 offers the highest current inventory (7037 units) and provides RoHS Compliant certification. The brass contact material and extended operating temperature range (-65°C to 105°C) support general-purpose applications. Insulation height variation (0.219" vs. 0.190") and contact length differences require PCB layout verification.

Samtec HTSW-103-08-S-D-RA delivers ROHS3 Compliant status with extended operating temperature capability (-55°C to 125°C) and liquid crystal polymer insulation. The shorter post length (0.090") suits applications with space constraints. Adequate inventory (2147 units) supports production requirements.

Samtec HTSW-103-09-F-D-RA provides ROHS3 Compliant certification with identical operating temperature range and insulation material as the HTSW-103-08-S-D-RA variant. The extended post length (0.290") accommodates deeper board penetration requirements. Lower inventory (755 units) may impact lead time for high-volume orders.

The original 78299-606 remains RoHS non-compliant; applications requiring RoHS certification must transition to one of the three substitute options.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 826634-3 directly replace the Amphenol ICC 78299-606 on existing PCBs?

A: Direct replacement requires verification of contact length and insulation height tolerances. The 826634-3 exhibits a longer mating contact (0.264" vs. 0.230") and increased insulation height (0.219" vs. 0.190"), which may affect mating depth and board clearance. PCB layout review is necessary before implementation.

Q: What is the primary difference between the two Samtec HTSW variants?

A: The HTSW-103-08-S-D-RA and HTSW-103-09-F-D-RA differ in post length. The -08 variant provides a 0.090" post for compact applications, while the -09 variant extends to 0.290" for deeper board penetration. Both share identical mating contact length, operating temperature range, and insulation material.

Q: Are all substitute parts compatible with the original connector housing and mating interfaces?

A: All substitutes maintain the 0.100" (2.54mm) pitch, 6-position, 2-row configuration with square contact geometry. Mechanical compatibility with existing mating connectors is established through these core parameters. Contact finish variations (gold thickness) do not affect mating compatibility.

Q: Which substitute part offers the best compliance profile for new designs?

A: Both Samtec options (HTSW-103-08-S-D-RA and HTSW-103-09-F-D-RA) provide ROHS3 Compliant certification and extended operating temperature ranges (-55°C to 125°C), supporting modern design standards. The TE Connectivity 826634-3 provides RoHS Compliant status with broader inventory availability.

Q: Does the insulation material change affect electrical performance?

A: The original 78299-606 does not specify insulation material. Substitute parts employ polybutylene terephthalate (PBT) or liquid crystal polymer (LCP) insulation. Both materials maintain UL94 V-0 flammability compliance and support the electrical requirements of 2.54mm pitch header applications. Material selection reflects design optimization within the substitution envelope.

Q: What inventory considerations apply to high-volume production?

A: TE Connectivity 826634-3 maintains the highest stock level (7037 units), followed by Samtec HTSW-103-08-S-D-RA (2147 units) and Samtec HTSW-103-09-F-D-RA (755 units). Lead time and supply chain continuity should inform part selection for sustained production volumes.
