Part Overview

The Amphenol ICC 78208-404 is a rectangular connector header designed for through-hole, right-angle mounting applications. This shrouded 4-position connector operates at 0.100" (2.54mm) pitch and features male pins with solder termination and friction lock fastening. The part is currently active in production with 1035 units in stock. Equivalent and substitute parts are identified to support design flexibility, supply chain continuity, and application-specific requirements where mechanical or electrical parameters align within acceptable tolerances.

Substitute Part Grouping Explanation

Substitution eligibility is determined by alignment in the following critical parameters:

Pitch - Mating: 0.100" (2.54mm) — mechanical compatibility with mating connectors
Number of Positions: 4 — circuit configuration match
Number of Rows: 1 — board layout compatibility
Mounting Type: Through Hole, Right Angle — PCB assembly process compatibility
Termination: Solder — assembly method compatibility
Contact Type: Male Pin — mating interface requirement
Material Flammability Rating: UL94 V-0 — safety compliance baseline

The three substitute parts listed below meet these core criteria. Variations in shrouding design, contact finish, insulation material, and fastening type are secondary parameters that do not prevent functional substitution when application requirements permit.

Engineering Selection Recommendations

All four parts are active products with UL94 V-0 flammability ratings and MSL 1 moisture sensitivity classification, indicating equivalent safety and handling characteristics.

78208-404 (Amphenol ICC): Primary specification. RoHS non-compliant status requires verification against regulatory requirements for the end application.

0022286043 (Molex KK254): Functionally compatible with core parameters. Unshrouded design and push-pull fastening differ from the primary part. Gold contact finish on mating surface provides enhanced corrosion resistance. ROHS3 compliant. Highest inventory availability (11635 units).

281698-4 (TE Connectivity HE13/HE14): Shrouded design and friction lock fastening match the primary part. Tin contact finish on mating surface. RoHS compliant. Operating temperature range specified (-40°C ~ 100°C). Highest inventory availability (18102 units).

281699-4 (TE Connectivity HE13/HE14): Shrouded design and friction lock fastening match the primary part. Gold contact finish on mating surface provides enhanced corrosion resistance compared to tin. RoHS compliant. Operating temperature range specified (-40°C ~ 100°C).

Selection between TE Connectivity variants (281698-4 vs. 281699-4) depends on contact finish requirements. Selection of the Molex part (0022286043) requires acceptance of unshrouded design and push-pull fastening differences.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0022286043 be used as a direct replacement for the Amphenol ICC 78208-404?

A: The Molex part meets core substitution criteria (4-position, 2.54mm pitch, through-hole right-angle, solder termination, male pins). However, it differs in shrouding (unshrouded vs. shrouded) and fastening type (push-pull vs. friction lock). These differences may affect mating connector compatibility and board layout. Verify mating connector specifications before substitution.

Q: What is the difference between the two TE Connectivity substitute parts (281698-4 and 281699-4)?

A: Both parts are mechanically and electrically identical. The primary difference is contact finish: 281698-4 features tin plating on mating contacts, while 281699-4 features gold plating. Gold plating provides superior corrosion resistance in high-humidity or corrosive environments. Tin plating is suitable for standard industrial applications.

Q: Are all substitute parts RoHS compliant?

A: The primary part (78208-404) is RoHS non-compliant. All three substitute parts are RoHS compliant (ROHS3 or RoHS Compliant status). Regulatory requirements for the end application determine whether RoHS compliance is mandatory.

Q: Do the substitute parts have specified operating temperature ranges?

A: The primary part (78208-404) does not specify an operating temperature range. Both TE Connectivity parts (281698-4 and 281699-4) specify -40°C ~ 100°C. The Molex part (0022286043) does not specify an operating temperature range. Verify temperature requirements against application specifications.

Q: What is the inventory status of each part?

A: Amphenol ICC 78208-404: 1035 units. Molex 0022286043: 11635 units. TE Connectivity 281698-4: 18102 units. TE Connectivity 281699-4: 4955 units. TE Connectivity 281698-4 has the highest availability.

Q: Can these parts be used interchangeably in the same PCB design?

A: Mechanical compatibility depends on PCB footprint design and mating connector specifications. Shrouded vs. unshrouded designs and friction lock vs. push-pull fastening may require footprint modifications. Consult PCB layout documentation and mating connector specifications before design changes.
