Amphenol ICC 78283-516 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 78283-516 is a rectangular connector header designed for through-hole mounting with 16 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This connector features shrouded 4-wall construction, press-fit and solder termination options, and gold-plated mating contacts with phosphor bronze material. The part is classified as obsolete, making identification of active equivalent components essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Amphenol ICC 78283-516 is determined by strict alignment of the following electrical and mechanical parameters:

• Connector type: Header
• Contact type: Male Pin
• Number of positions: 16
• Number of rows: 2
• Pitch - mating: 0.100" (2.54mm)
• Row spacing - mating: 0.100" (2.54mm)
• Shrouding: Shrouded - 4 Wall
• Mounting type: Through Hole
• Style: Board to Cable/Wire
• Contact shape: Square
• Material flammability rating: UL94 V-0

The substitute parts identified below maintain these core parameters. Variations in contact length, insulation height, contact finish thickness, insulation material composition, and fastening type are permitted within the scope of functional equivalence, provided the primary mating and mounting characteristics remain unchanged.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol ICC 78283-516 is obsolete and no longer in active production. All identified substitute parts maintain the critical mating and mounting parameters required for functional equivalence.

Molex 0015477716 is the manufacturer-recommended substitute. This part is active and ROHS3 compliant, addressing regulatory requirements not met by the original component. It features solder-only termination and latch holder fastening, differing from the original push-pull mechanism.

HARTING 09185166322, 09185167322, and 09185167324 are active alternatives from the SEK series. All three maintain core connector specifications and provide ROHS3 compliance. These parts feature latch holder fastening and solder termination. The primary distinction among the three HARTING options is contact length on the post: 09185166322 and 09185167322 specify 0.177" (4.50mm), while 09185167324 specifies 0.114" (2.90mm). All three provide specified operating temperature range of -55°C to 125°C.

Selection between substitute options should be based on packaging requirements (tube, bulk, or tray), inventory availability, and specific post length requirements for your application's PCB thickness and assembly process.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0015477716 directly replace the Amphenol ICC 78283-516?

A: The Molex 0015477716 maintains all critical mating and mounting parameters: 16 positions, 2 rows, 0.100" pitch, shrouded 4-wall construction, and through-hole mounting. The fastening mechanism differs (latch holder versus push-pull), and termination is solder-only rather than press-fit and solder. These differences do not affect functional equivalence for standard board-to-cable applications.

Q: What is the difference between the three HARTING substitute options?

A: All three HARTING parts (09185166322, 09185167322, 09185167324) are from the SEK series and share identical mating and mounting specifications. The primary difference is contact post length: 09185166322 and 09185167322 feature 0.177" (4.50mm) posts, while 09185167324 features 0.114" (2.90mm) posts. Selection depends on your PCB thickness and solder joint requirements. Packaging also differs: 09185166322 is supplied in bulk, 09185167322 in bulk, and 09185167324 in tray.

Q: Are all substitute parts RoHS compliant?

A: The original Amphenol ICC 78283-516 is RoHS non-compliant. All identified substitutes—Molex 0015477716 and all three HARTING options—are ROHS3 compliant, meeting current regulatory requirements.

Q: What is the operating temperature range for substitute parts?

A: The Molex 0015477716 does not specify an operating temperature range. The three HARTING substitutes specify -55°C to 125°C. The original part does not provide operating temperature data.

Q: Do the substitute parts have the same contact finish specifications?

A: All parts feature gold-plated mating contacts. The original Amphenol ICC part specifies GXT™ gold with 30.0µin (0.76µm) thickness. The Molex 0015477716 specifies gold with matching 30.0µin (0.76µm) thickness. The HARTING parts specify gold mating contact finish but do not provide thickness specifications.

Q: What insulation materials are used in the substitute parts?

A: The original part uses polyester with glass filler. The Molex 0015477716 uses liquid crystal polymer (LCP) with glass filler. The three HARTING substitutes use polybutylene terephthalate (PBT) with glass filler. All materials meet UL94 V-0 flammability requirements.

Q: Are there packaging considerations when selecting a substitute?

A: Yes. The Molex 0015477716 is supplied in tube packaging. HARTING 09185166322 is supplied in bulk, 09185167322 in bulk, and 09185167324 in tray. Packaging selection affects handling, storage, and assembly processes. Current inventory levels are: Molex 1050 pcs, HARTING 09185166322 693 pcs, HARTING 09185167322 1151 pcs, and HARTING 09185167324 2088 pcs.
