Amphenol ICC 78299-520 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 78299-520 is a rectangular connector header featuring a right-angle, through-hole mount configuration with 20 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This connector belongs to the BERGSTIK® II series and is classified as an active product with 701 units currently in stock. The part is designed for board-to-board applications requiring press-fit and solder termination with push-pull fastening. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, ensuring functional compatibility in applications where the primary part may be unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 78299-520 are qualified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Connector type (Header)
• Contact type (Male Pin)
• Pitch - Mating (0.100" / 2.54mm)
• Number of positions (20)
• Number of rows (2)
• Row spacing - Mating (0.100" / 2.54mm)
• Mounting type (Through Hole, Right Angle)
• Fastening type (Push-Pull)
• Contact shape (Square)
• Material flammability rating (UL94 V-0)

Secondary Compatibility Factors:

• Termination method (Press-Fit, Solder or Solder)
• Contact finish (Gold or equivalent)
• Insulation material (varies by substitute)
• Operating temperature range (where specified)
• RoHS compliance status

The two identified substitutes—TE Connectivity AMP Connectors 1-826634-0 and Samtec Inc. HTSW-110-08-L-D-RA-001—meet all primary matching criteria and are therefore electrically and mechanically compatible with the original part for board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: Amphenol ICC 78299-520

• Active product status with established supply (701 units in stock)
• RoHS non-compliant; suitable for applications without RoHS requirements
• Phosphor bronze contact material with gold finish
• MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints

Substitute 1: TE Connectivity AMP Connectors 1-826634-0

• Active product with higher inventory availability (2,890 units in stock)
• RoHS Compliant; suitable for applications requiring RoHS adherence
• Brass contact material with gold mating finish and tin post finish
• Operating temperature range: -65°C ~ 105°C
• Current rating: 5A
• Breakaway connector option provides additional application flexibility
• MSL rating of 1 (Unlimited) matches original part

Substitute 2: Samtec Inc. HTSW-110-08-L-D-RA-001

• Active product with moderate inventory (999 units in stock)
• ROHS3 Compliant; meets current RoHS requirements
• Phosphor bronze contact material matching original part
• Operating temperature range: -55°C ~ 125°C (extended upper limit)
• Liquid Crystal Polymer (LCP) insulation material
• 19 positions loaded (versus 20 in original); verify application requirements
• MSL rating: Not Applicable

Selection between substitutes depends on RoHS compliance requirements, operating temperature specifications, and inventory availability. The TE Connectivity part offers RoHS compliance with higher stock levels. The Samtec part provides extended temperature range and ROHS3 compliance with phosphor bronze contacts matching the original material specification.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-826634-0 be used as a direct replacement for the Amphenol ICC 78299-520?

A: Yes, the TE Connectivity part is electrically and mechanically compatible. Both connectors share identical pitch (0.100" / 2.54mm), position count (20), row configuration (2 rows), mounting type (through-hole right-angle), and fastening mechanism (push-pull). The primary difference is RoHS compliance status; the TE Connectivity part is RoHS Compliant while the original is non-compliant. Verify your application's RoHS requirements before selection.

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

A: The breakaway feature on the 1-826634-0 indicates that individual connector sections can be separated from the main assembly. This provides application flexibility for board-to-board or cable configurations. The original Amphenol part is specified for board-to-board style only, so the breakaway capability represents an additional feature rather than a limitation.

Q: Why does the Samtec HTSW-110-08-L-D-RA-001 show 19 positions loaded instead of 20?

A: The Samtec part specification indicates 19 positions loaded out of 20 total positions. This means one position in the connector is not populated with a contact. Verify that your application uses only 19 signal connections or confirm with the manufacturer whether all 20 positions can be populated if required.

Q: Are there differences in contact length between these parts?

A: Yes. The Amphenol 78299-520 has a mating contact length of 0.230" (5.84mm), the TE Connectivity 1-826634-0 has 0.264" (6.70mm), and the Samtec HTSW-110-08-L-D-RA-001 has 0.230" (5.84mm). These variations may affect mating depth and connector stack height. Verify compatibility with your mating connector specifications.

Q: Which substitute part offers the widest operating temperature range?

A: The Samtec HTSW-110-08-L-D-RA-001 provides an operating temperature range of -55°C ~ 125°C, compared to the TE Connectivity part at -65°C ~ 105°C and the original Amphenol part with no specified operating temperature. Select the Samtec part if your application requires operation at temperatures above 105°C.

Q: What is the difference in contact material between these connectors?

A: The Amphenol 78299-520 and Samtec HTSW-110-08-L-D-RA-001 both use phosphor bronze contacts. The TE Connectivity 1-826634-0 uses brass contacts. Phosphor bronze typically offers superior spring properties and durability in high-cycle mating applications, while brass provides good electrical conductivity. Both materials are acceptable for standard board-to-board applications.

Q: Are all three parts UL94 V-0 rated?

A: Yes, all three connectors carry a UL94 V-0 material flammability rating, indicating compliance with flame retardancy requirements for electrical and electronic equipment.
