Amphenol ICC 71922-126 Rectangular Connector Header – Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 71922-126 is a through-hole, right-angle rectangular connector header with 26 positions at 0.100" (2.54mm) pitch, configured as a 2-row shrouded design with male pins. This connector is classified as obsolete, which necessitates identification of active equivalent and substitute parts for ongoing design support and procurement.

The 71922-126 features gold-plated mating contacts with phosphor bronze material, thermoplastic glass-filled insulation, and latch lock/eject hook fastening. With UL94 V-0 flammability rating and RoHS non-compliant status, alternative parts must be evaluated for compliance requirements and functional compatibility.

Engineering Selection Recommendations

Primary Substitute – Amphenol ICC 71922-126LF: The 71922-126LF is the direct functional equivalent manufactured by the original supplier. It maintains identical electrical and mechanical specifications while transitioning to RoHS Compliant status. This part is recommended for designs requiring continuity with the original Amphenol ICC Quickie™ series and is currently in active production with substantial inventory availability (3556 units).

Secondary Substitutes – HARTING SEK Series (09185265911, 09185265913, 09185266911, 09185266913, 09185267911, 09185267913): These HARTING parts are manufacturer-recommended alternatives that meet all critical electrical and mechanical parameters. All are ROHS3 Compliant and in active production. Differentiation among these variants is based on contact length specifications:

Parts ending in "11" or "911": Contact Length - Post 0.177" (4.50mm)
Parts ending in "13" or "913": Contact Length - Post 0.114" (2.90mm)

Selection between these variants depends on application-specific post length requirements. All maintain the same mating contact length (0.240" / 6.10mm) and insulation height (0.335" / 8.51mm).

Alternative Substitute – HARTING 09195266903: This variant uses Polycyclohexylenedimethylene Terephthalate (PCT) glass-filled insulation instead of PBT, with beige insulation color. It is ROHS3 Compliant and active. This part is suitable for applications where insulation material composition is not design-critical.

Alternative Substitute – Amphenol CONEC 141A10959X: This part offers ROHS3 Compliance and active status with a current rating of 1A specified. It is suitable for applications with defined current requirements and represents an alternative source from the Amphenol family.

Frequently Asked Questions (FAQ)

Q: Can the 71922-126 be directly replaced with the 71922-126LF? A: Yes. The 71922-126LF is the direct successor from Amphenol ICC. Both parts share identical connector type, pitch, position count, row configuration, mounting style, shrouding, and termination method. The primary difference is RoHS compliance status, with the 71922-126LF meeting RoHS requirements.

Q: What is the difference between HARTING parts ending in "11/911" and "13/913"? A: The difference is in the contact post length. Parts designated "11" or "911" have a post length of 0.177" (4.50mm), while parts designated "13" or "913" have a post length of 0.114" (2.90mm). The mating contact length remains constant at 0.240" (6.10mm) across all variants. Selection depends on PCB pad depth and solder joint requirements.

Q: Are HARTING SEK series parts electrically compatible with the original 71922-126? A: Yes. All HARTING SEK series substitutes maintain the same pitch (2.54mm), position count (26), row configuration (2 rows), shrouding (4-wall), and termination method (solder). Contact material differs (copper alloy vs. phosphor bronze) and insulation material is PBT glass-filled instead of thermoplastic glass-filled, but these differences do not affect electrical compatibility for standard applications.

Q: What is the significance of the "LF" designation in 71922-126LF? A: The "LF" suffix indicates lead-free compliance, reflecting RoHS Directive adherence. This designation confirms that the part meets current environmental and regulatory requirements for electronic components.

Q: Can I use the HARTING 09195266903 if my design specifies thermoplastic or PBT insulation? A: The 09195266903 uses PCT (Polycyclohexylenedimethylene Terephthalate) glass-filled insulation instead of PBT. If your design has specific insulation material requirements, this part may not be suitable. Refer to design specifications for insulation material constraints before selection.

Q: What packaging options are available for these substitutes? A: The 71922-126LF is supplied in tube packaging. HARTING parts (09185265911, 09185265913, 09185266911, 09185266913, 09185267911, 09185267913, 09195266903) and the Amphenol CONEC 141A10959X are supplied in bulk packaging. Packaging selection may affect procurement logistics and handling procedures.

Q: Are all substitute parts RoHS compliant? A: The 71922-126LF is RoHS Compliant. All HARTING parts and the Amphenol CONEC 141A10959X are ROHS3 Compliant. The original 71922-126 is RoHS non-compliant. For applications requiring RoHS compliance, select from the compliant alternatives listed above.

Q: What is the operating temperature range for these connectors? A: The original 71922-126 does not specify an operating temperature range. HARTING parts specify -55°C to 125°C. The Amphenol CONEC 141A10959X does not specify an operating temperature range. Verify application temperature requirements against available specifications before final selection.
