Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 5111824-9 is determined by strict alignment with the following core parameters: 40-position connector header configuration, 2-row layout, 0.100" (2.54mm) mating pitch, 0.100" (2.54mm) row spacing, shrouded 4-wall design, through-hole mounting, solder termination, square contact shape, and UL94 V-0 flammability rating. All identified substitute parts meet these mandatory criteria. Secondary parameters including contact length dimensions, insulation height, contact finish specifications, and operating temperature ranges vary among substitutes but remain within acceptable tolerances for rectangular connector header applications. Substitute parts are grouped by manufacturer: Amphenol ICC (FCI) Quickie™ series (53611-S40-6LF and 71918-140LF) and 3M 3000 series (N3432-6302RB and N3432-6303RB). Packaging format differences (Tray, Tube, Bulk) and inventory availability are secondary considerations that do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and RoHS compliance, meeting regulatory requirements equivalent to the primary TE Connectivity 5111824-9 part. The 3M 3000 series parts (N3432-6302RB and N3432-6303RB) provide higher current rating capability at 1.75A per contact compared to the primary part's 1A rating, with operating temperature range of -55°C to 105°C. The Amphenol ICC Quickie™ series parts (53611-S40-6LF and 71918-140LF) maintain the same core electrical and mechanical specifications but do not specify current or voltage ratings in available documentation. Contact length variations exist across all substitutes, with the 3M parts matching the primary part's 0.240" (6.10mm) mating contact length. Insulation height differences range from 0.549" to 0.685", which may affect board layout considerations. All parts feature identical pitch, row spacing, shrouding configuration, and flammability rating. Selection should be based on specific application requirements regarding current capacity, operating temperature range, and packaging format availability.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 53611-S40-6LF be used as a direct replacement for the TE Connectivity 5111824-9?

A: The 53611-S40-6LF meets all core mechanical and electrical compatibility criteria: 40-position, 2-row configuration, 0.100" (2.54mm) pitch, shrouded 4-wall design, through-hole solder termination, and UL94 V-0 rating. However, the mating contact length is 0.230" (5.84mm) versus 0.240" (6.10mm) on the primary part, and current/voltage ratings are not specified for the Amphenol part. Compatibility depends on application-specific requirements for contact engagement depth and electrical performance.

Q: What are the key differences between the 3M N3432-6302RB and N3432-6303RB?

A: Both 3M parts share identical core specifications: 40-position, 2-row, 0.100" (2.54mm) pitch, shrouded 4-wall, through-hole solder termination, and 1.75A current rating. The primary difference is contact length on the post: N3432-6302RB features 0.112" (2.84mm) post length, while N3432-6303RB features 0.155" (3.94mm) post length. This affects overall connector height and board penetration depth. Packaging also differs: N3432-6302RB is supplied in Tray format, while N3432-6303RB is supplied in Bulk format.

Q: Are there operating temperature limitations when substituting with Amphenol ICC parts?

A: Operating temperature specifications are not provided for the Amphenol ICC Quickie™ series parts (53611-S40-6LF and 71918-140LF). The primary TE Connectivity part operates from -65°C to 105°C, while the 3M 3000 series parts operate from -55°C to 105°C. If the application requires operation below -55°C, the 3M parts may not be suitable. Amphenol ICC specifications should be obtained directly from the manufacturer for temperature-dependent applications.

Q: Do packaging format differences affect electrical performance?

A: Packaging format (Tray, Tube, or Bulk) does not affect electrical or mechanical performance of the connector itself. Packaging differences impact handling, storage, and inventory management only. Selection between Tray, Tube, and Bulk packaging should be based on assembly process requirements and supply chain logistics rather than technical compatibility.

Q: What is the significance of the contact finish thickness variations?

A: Contact finish thickness affects durability and wear resistance during mating cycles. The primary TE Connectivity part specifies 30.0µin (0.76µm) mating contact finish thickness. The Amphenol ICC 53611-S40-6LF specifies 15.0µin (0.38µm), which is thinner and may result in reduced contact life under high-cycle mating applications. The 3M and Amphenol ICC 71918-140LF parts match the primary part's 30.0µin specification. Post contact finish thickness also varies: the primary part specifies 100.0µin (2.54µm), while 3M parts specify 200.0µin (5.08µm), providing enhanced solder joint durability.

Q: Can the 71918-140LF be used in applications requiring the primary part's 250VAC rating?

A: The Amphenol ICC 71918-140LF does not specify voltage rating in available documentation. The primary TE Connectivity 5111824-9 is rated for 250VAC. For applications with specific voltage requirements, the 3M 3000 series parts are recommended, though voltage ratings are also not specified for these parts. Voltage capability should be confirmed with the manufacturer before substitution in high-voltage applications.

Q: What is the impact of insulation height differences on PCB design?

A: Insulation height varies significantly across substitutes: primary part 0.549" (13.94mm), Amphenol ICC 53611-S40-6LF 0.640" (16.26mm), Amphenol ICC 71918-140LF 0.685" (17.40mm), and 3M parts 0.680" (17.27mm). Greater insulation height increases the connector's profile above the PCB, which may affect component placement density and clearance to adjacent components. PCB layout must accommodate the specific insulation height of the selected substitute part.

Q: Are all substitute parts RoHS compliant?

A: Yes, all identified substitute parts are RoHS Compliant. The primary TE Connectivity 5111824-9 and all four substitute parts (53611-S40-6LF, 71918-140LF, N3432-6302RB, and N3432-6303RB) meet RoHS requirements. Moisture Sensitivity Level is 1 (Unlimited) for all parts, indicating no special moisture handling requirements during storage or assembly.
