Amphenol ICC 78229-102 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 78229-102 is a rectangular connector header designed for through-hole mounting applications. This 2-position, 0.100" (2.54mm) pitch connector operates in the BERGSTIK® II series and is classified as Active product status. The connector features unshrouded, board-to-board configuration with press-fit and solder termination options. Substitute parts are necessary when the primary part experiences supply constraints, when alternative compliance certifications are required, or when design specifications permit equivalent electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the 78229-102 is determined by the following critical parameters:

Pitch - Mating: 0.100" (2.54mm) — exact match required
Number of Positions: 2 — exact match required
Number of Rows: 1 — exact match required
Mounting Type: Through Hole — exact match required
Contact Type: Male Pin — exact match required
Connector Type: Header (with or without breakaway feature) — functionally compatible
Style: Board to Board or Board to Board/Cable — functionally compatible
Material Flammability Rating: UL94 V-0 — exact match required
Shrouding: Unshrouded — exact match required

All three substitute parts (826648-2, 929700-01-02-RK, 929705-11-02-EU) meet these critical parameters and are therefore electrically and mechanically interchangeable with the 78229-102 in applications where the specified tolerances and material compositions are acceptable.

Engineering Selection Recommendations

All three substitute parts maintain Active product status and meet the core electrical and mechanical requirements of the 78229-102. Selection among substitutes should be based on the following compliance and certification factors:

RoHS Compliance: The 78229-102 is RoHS non-compliant. If RoHS compliance is required for the application, all three substitutes (826648-2, 929700-01-02-RK, 929705-11-02-EU) are RoHS Compliant alternatives.

Operating Temperature Range: The 78229-102 does not specify an operating temperature range. The TE Connectivity 826648-2 provides the widest operating range (-65°C ~ 105°C), while both 3M parts (929700-01-02-RK and 929705-11-02-EU) operate from -40°C ~ 105°C.

Current Rating: The 78229-102 does not specify a current rating. The TE Connectivity 826648-2 is rated for 5A, while both 3M parts are rated for 2.5A. Applications requiring higher current capacity should prioritize 826648-2.

Contact Finish: The 78229-102 specifies gold or gold GXT™ finish on mating contacts. The TE Connectivity 826648-2 and 3M 929705-11-02-EU both provide gold mating contact finish. The 3M 929700-01-02-RK uses tin finish on mating contacts and may be selected only if tin contact finish is acceptable for the application.

Termination Options: The 78229-102 supports both press-fit and solder termination. All three substitutes support solder termination only. Applications requiring press-fit termination cannot use these substitutes.

Frequently Asked Questions (FAQ)

Q: Can the 78229-102 be directly replaced with any of these substitute parts?

A: Yes, all three substitute parts are electrically and mechanically interchangeable with the 78229-102 in applications where the specified contact finishes, materials, and termination methods are acceptable. The critical matching parameters are pitch (0.100"), position count (2), row count (1), mounting type (through hole), and connector type (header).

Q: What is the difference between the three substitute parts?

A: The primary differences are manufacturer, contact finish on mating surfaces, contact material composition, insulation material, operating temperature range, and current rating. The TE Connectivity 826648-2 offers the widest operating temperature range and highest current rating. The 3M 929705-11-02-EU matches the gold contact finish of the original part. The 3M 929700-01-02-RK uses tin finish and should be selected only when tin contact finish is compatible with the application.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts (826648-2, 929700-01-02-RK, 929705-11-02-EU) are RoHS Compliant. The original 78229-102 is RoHS non-compliant. If RoHS compliance is a requirement, any of the three substitutes can be used.

Q: Does the breakaway feature on the substitute parts affect compatibility?

A: No. The breakaway feature on the TE Connectivity 826648-2 and both 3M parts is an additional capability that does not affect compatibility with the original 78229-102. The connector will function identically in board-to-board applications whether or not the breakaway feature is utilized.

Q: What is the difference in contact length between these parts?

A: Contact length variations are minor and within acceptable tolerances for standard 2.54mm pitch header applications. The overall contact lengths range from 0.528" (929700-01-02-RK) to 0.551" (826648-2), compared to 0.538" for the original part. These variations do not affect mechanical or electrical compatibility in standard PCB applications.

Q: Can I use the 929700-01-02-RK if my application requires gold contact finish?

A: No. The 929700-01-02-RK uses tin finish on mating contacts, not gold. If gold contact finish is required, select either the 826648-2 or 929705-11-02-EU.

Q: Which substitute part should I choose for high-temperature applications?

A: The TE Connectivity 826648-2 supports the widest operating temperature range (-65°C ~ 105°C). Both 3M parts operate from -40°C ~ 105°C. For applications requiring operation below -40°C, the 826648-2 is the appropriate choice.

Q: Are there any termination differences I should be aware of?

A: Yes. The original 78229-102 supports both press-fit and solder termination. All three substitute parts support solder termination only. If your application requires press-fit termination, these substitutes are not compatible.
