Engineering Selection Recommendations

Direct Amphenol ICC Equivalent: The 76314-209LF is the active production equivalent of the obsolete 76314-209. Both parts share identical electrical and mechanical specifications with the primary difference being RoHS compliance status. The 76314-209LF is RoHS Compliant and REACH Affected, making it the preferred choice for new designs requiring regulatory compliance while maintaining full form, fit, and function compatibility.

Molex C-Grid 71850 Series (0015445118, 0015445818, 0015446818): These Molex receptacles meet all primary compatibility criteria and are active production parts with ROHS3 compliance. The 0015445118 and 0015445818 feature gold mating contact finish identical to the 76314-209, while 0015446818 provides tin mating contact finish. All three support operating temperatures of -40°C to 105°C or -40°C to 125°C with 2.5A current rating and 500VAC voltage rating. Contact material is phosphor bronze rather than brass, providing enhanced durability. These parts are suitable for applications requiring higher electrical specifications and extended temperature ranges.

Samtec CLH-109-F-D-PE: This pass-through receptacle connector meets all primary compatibility criteria with ROHS3 compliance and active product status. The CLH series features a low-profile design with 0.140" insulation height compared to 0.335" for the 76314-209, making it suitable for space-constrained applications. Operating temperature range extends to -65°C to 125°C. Contact material is phosphor bronze with gold mating finish.

Samtec ESD-109 Series (ESD-109-G-03, ESD-109-G-06, ESD-109-G-23, ESD-109-G-26, ESD-109-G-28): These elevated socket connectors meet all primary compatibility criteria with ROHS3 compliance and active product status. The ESD series differs in contact post length, ranging from 0.090" to 0.365", allowing selection based on specific board thickness and stacking height requirements. All variants feature beryllium copper contacts with gold finish on both mating and post surfaces, operating across -55°C to 125°C. These connectors are suitable for applications requiring elevated socket geometry and enhanced contact performance.

Frequently Asked Questions (FAQ)

Q: Can the 76314-209 be directly replaced with the 76314-209LF? A: Yes. The 76314-209LF is the active production equivalent with identical form, fit, and function. The primary difference is RoHS compliance status. The 76314-209LF is suitable for direct replacement in new designs and legacy system updates.

Q: What are the key differences between Amphenol ICC and Molex substitutes? A: Amphenol ICC parts (76314-209, 76314-209LF) use brass contacts, while Molex C-Grid 71850 series use phosphor bronze contacts. Molex parts provide specified current ratings (2.5A) and voltage ratings (500VAC) with extended operating temperature ranges (-40°C to 125°C). Insulation material differs: Amphenol uses polyester while Molex uses liquid crystal polymer (LCP).

Q: Are Samtec ESD-109 connectors compatible with standard 0.100" pitch headers? A: Yes. All ESD-109 variants maintain 0.100" (2.54mm) pitch and 0.100" row spacing, ensuring mechanical compatibility with standard headers. The primary distinction is the elevated socket design and variable contact post lengths, which accommodate different board thicknesses and stacking configurations.

Q: Which substitute part should be selected for new designs requiring RoHS compliance? A: All substitute parts listed (76314-209LF, Molex 0015445118/0015445818/0015446818, Samtec CLH-109-F-D-PE, and all ESD-109 variants) are RoHS Compliant or ROHS3 Compliant. Selection should be based on specific application requirements including operating temperature, current/voltage specifications, and form factor constraints.

Q: What is the difference between the Samtec CLH-109-F-D-PE and ESD-109 series? A: The CLH-109-F-D-PE is a pass-through connector with low-profile insulation height (0.140"), suitable for compact designs. The ESD-109 series are elevated socket connectors with standard insulation height (0.300") and variable contact post lengths (0.090" to 0.365"), providing flexibility for different board thickness applications.

Q: Can the 76314-209 be used in new production designs? A: No. The 76314-209 is classified as obsolete. New designs must use active production equivalents such as 76314-209LF or cross-manufacturer alternatives. Obsolete parts have limited availability and no manufacturer support.

Q: Are there electrical performance differences between gold and tin mating contact finishes? A: The 76314-209 and most substitutes feature gold mating contact finish. The Molex 0015446818 provides tin mating contact finish as an alternative. Gold finish offers superior corrosion resistance and lower contact resistance. Tin finish is suitable for applications where cost optimization is prioritized and environmental conditions do not require enhanced corrosion protection.
