Amphenol ICC 69155-120 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 69155-120 is a rectangular connector header featuring a right-angle through-hole mount configuration with 20 positions at 2.54mm pitch. This connector is part of the Quickie™ series and is classified as obsolete. Due to its obsolete status, identifying functionally equivalent substitute parts is essential for design continuity, board redesigns, and production sourcing. The substitute parts listed maintain the core electrical and mechanical specifications required for direct functional replacement in applications requiring 20-position, 2.54mm pitch header connectors with right-angle mounting.

Engineering Selection Recommendations

All listed substitute parts maintain active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The 69155-120 is RoHS non-compliant and obsolete, making migration to compliant alternatives necessary for new designs and production continuity.

Primary Substitutes (Highest Compatibility):

Molex 0702472052, TE Connectivity 2-1761605-7, and Samtec HTST-110-04-S-D-RA are recommended as primary substitutes. These parts maintain push-pull fastening mechanisms consistent with the original design, active product status, and full ROHS3 compliance. The Samtec HTST series offers enhanced current rating (3.4A per contact) and superior temperature range (-55°C to 125°C), providing performance margin for demanding applications.

Secondary Substitutes (Latch Holder Configuration):

HARTING SEK series connectors (09185205323, 09185206323, 09185207323, 09195206323) employ latch holder fastening instead of push-pull mechanisms. These parts are suitable for applications where latch-based mating is acceptable and provide active product status with ROHS3 compliance. Operating temperature range extends to -55°C to 125°C.

Vertical Mount Alternative:

HARTING 09185206904001 provides equivalent electrical specifications with vertical through-hole mounting. This part is applicable only when board layout permits vertical header orientation and does not require right-angle geometry.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different fastening type (latch holder vs. push-pull)?

A: Fastening type differences affect mating interface behavior but do not prevent functional substitution if the mating connector is compatible with the fastening mechanism. Verify that the mating connector (socket or receptacle) is designed for the substitute's fastening type before implementation.

Q: What is the significance of contact shape differences (circular vs. square)?

A: Contact shape affects mating force and contact pressure distribution. Circular contacts (original 69155-120) and square contacts (most substitutes) are not interchangeable within the same mating interface. Ensure the mating connector is designed for the substitute part's contact geometry.

Q: Are the Samtec HTST series parts direct replacements?

A: Yes, Samtec HTST-110-04-S-D-RA, HTST-110-04-L-D-RA, and HTST-110-04-G-D-RA are direct right-angle substitutes with identical pitch, position count, and mounting configuration. The HTST series offers enhanced current rating (3.4A per contact) and extended temperature range, making them suitable for applications requiring higher performance margins.

Q: Why is the original 69155-120 marked as obsolete?

A: Obsolescence reflects discontinuation by the manufacturer. Active substitute parts ensure design continuity and production availability. Migration to active alternatives is recommended for new designs and ongoing production.

Q: What is the impact of insulation material differences?

A: Insulation materials (polyester, PBT, PCT, LCP) affect thermal stability, moisture absorption, and mechanical properties. All listed materials maintain UL94 V-0 flammability rating. LCP (Samtec HTST series) offers superior thermal and dimensional stability compared to polyester or PBT, beneficial for high-temperature or high-reliability applications.

Q: Can I substitute a vertical mount header (09185206904001) for a right-angle header?

A: Vertical mount headers require different board layout and mating connector orientation. Substitution is possible only if the application permits vertical header mounting and the mating connector is compatible with vertical orientation.

Q: What does ROHS3 compliance mean for my application?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. All active substitutes are ROHS3 compliant, whereas the original 69155-120 is non-compliant. Compliance is mandatory for many regulated industries and markets.

Q: Are there packaging differences between substitutes?

A: Yes. Molex 0702472052 is supplied in bulk packaging, HARTING parts in bulk or tray, TE Connectivity 2-1761605-7 in bulk, and Samtec HTST series in tube packaging. Packaging affects handling, storage, and cost but does not affect electrical or mechanical performance.
