Amphenol ICC 68705-409HLF Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68705-409HLF is a rectangular connector header for through-hole mounting with 9 positions at 0.100" (2.54mm) pitch. This BERGSTIK® II series connector is designed for board-to-board applications with male pin contacts, solder termination, and push-pull fastening. The part is currently active in production with 1146 units in stock.

Substitute parts are necessary when the original part becomes unavailable, when alternative compliance certifications are required, or when design specifications allow for compatible connector architectures from different manufacturers while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution compatibility for the 68705-409HLF is determined by the following critical parameters:

Pitch and Position Count: All substitutes must maintain 0.100" (2.54mm) pitch with 9 positions in a single row to ensure mechanical fit with mating connectors
Connector Architecture: Header type with male pin contacts for board-to-board or board-to-cable applications
Mounting and Termination: Through-hole solder termination is required for PCB integration
Electrical Ratings: Current and voltage ratings must meet or exceed the application requirements
Compliance: RoHS and flammability certifications determine suitability for regulated applications

The substitute parts listed below meet these core criteria. Variations in contact finish, insulation material, contact length, and operating temperature ranges represent design trade-offs that do not prevent functional substitution when application requirements permit.

Engineering Selection Recommendations

Primary Substitutes (Active Status, Full Compliance)

The following parts are recommended as direct substitutes based on active product status and RoHS compliance:

5-146278-9 (TE Connectivity AMPMODU Mod II): Active status, ROHS3 compliant, tin contact finish, copper alloy material, LCP insulation. Suitable for applications where tin finish is acceptable.
5-146280-9 (TE Connectivity AMPMODU Mod II): Active status, RoHS compliant, gold contact finish, copper alloy material, LCP insulation. Recommended for applications requiring enhanced corrosion resistance.

Current Rating Consideration

The main part 68705-409HLF is rated for 5A. Most substitute parts are rated for 3A. Applications requiring 5A current capacity should confirm that the 3A-rated substitutes are acceptable for the specific circuit design, or select alternatives with higher current ratings if available.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a lower current rating (3A vs. 5A)?

A: Current rating compatibility depends on your circuit design. If your application draws less than 3A per contact, a 3A-rated substitute is acceptable. If your design requires 5A capacity, you must either confirm that the substitute's 3A rating is sufficient for your actual current draw, or select an alternative part with a 5A or higher rating.

Q: What is the difference between tin and gold contact finishes?

A: Tin finish provides cost-effective corrosion resistance suitable for standard applications. Gold finish offers superior corrosion resistance and lower contact resistance, making it preferable for high-reliability applications or environments with corrosive exposure. Both finishes are electrically compatible with standard mating connectors.

Q: Are breakaway connector variants compatible with non-breakaway designs?

A: Breakaway variants (such as 4-103741-0-09, 5-146278-9, 5-146280-9, PBC09SAAN, and PEC09SAAN) feature segmented insulation that allows individual positions to be separated. These are mechanically and electrically compatible with standard non-breakaway headers when used in non-breakaway applications. The breakaway feature is optional and does not prevent substitution.

Q: What does ROHS3 compliance mean compared to RoHS compliance?

A: RoHS (Restriction of Hazardous Substances) compliance restricts specific hazardous materials. ROHS3 refers to RoHS 3 (Directive 2015/863/EU), which includes additional restricted substances beyond the original RoHS directive. ROHS3 compliant parts meet current EU environmental standards. Parts marked as RoHS compliant (without the "3" designation) meet the original RoHS requirements and are generally acceptable for most applications, though ROHS3 compliant parts are preferred for new designs.

Q: Why is 4-103741-0-09 marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. While the part may still be available from inventory, it is not recommended for new designs. Obsolete parts may have limited availability and no manufacturer support. Use active-status substitutes for new applications.

Q: Can I use a connector with a different operating temperature range?

A: Operating temperature range compatibility depends on your application environment. If your application operates within the substitute part's temperature range, it is acceptable. For example, if your application operates at -40°C to +85°C, a part rated for -65°C ~ 125°C is suitable. Conversely, if your application requires -55°C operation and a substitute is only rated to -40°C, that substitute is not appropriate.

Q: What is the difference between through-hole and kinked pin termination?

A: Through-hole termination uses straight pins inserted perpendicular to the PCB. Kinked pin termination (as in HTSW-109-07-F-S-LL) uses pins with a bend, allowing the connector to be mounted at an angle or in confined spaces. Both termination types are solder-compatible and electrically equivalent. Selection depends on mechanical mounting requirements.

Q: Are Samtec TS-109 series parts (TS-109-G-AA, TS-109-T-A-1) fully compatible?

A: TS-109 series parts are compatible with the 68705-409HLF in terms of pitch, position count, and electrical function. However, detailed mechanical specifications (contact length, insulation height, overall dimensions) differ slightly. Confirm mechanical fit with your mating connector before substitution. Both TS-109 variants are electrically equivalent; selection between gold and tin finish depends on application requirements.
