Amphenol ICC 78208-504 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 78208-504 is a rectangular connector header designed for through-hole, right-angle mounting applications. This shrouded 4-position header 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 817 units in stock. Equivalent parts are necessary when primary inventory is unavailable, when design requirements permit alternative contact finishes or shrouding configurations, or when supply chain optimization requires sourcing from multiple manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 78208-504 is determined by the following core parameters: 0.100" (2.54mm) mating pitch, 4-position single-row configuration, male pin contact type, through-hole right-angle mounting, solder termination, and square contact geometry. All listed substitute parts meet these fundamental requirements.

The three qualified substitutes differ in secondary characteristics that do not affect basic mating compatibility:

Shrouding Configuration: The main part features shrouded 2-wall design. Substitute 0022286043 (Molex) is unshrouded, while 281698-4 and 281699-4 (TE Connectivity) maintain shrouded 2-wall configuration.

Contact Finish - Mating: The main part specifies gold or gold GXT™. Substitute 0022286043 uses gold finish. Substitute 281698-4 uses tin finish. Substitute 281699-4 uses gold finish.

Fastening Type: The main part uses friction lock. Substitute 0022286043 uses push-pull fastening. Substitutes 281698-4 and 281699-4 use friction lock.

Insulation Material: The main part uses PCT glass-filled material. Substitute 0022286043 uses polyamide (PA) nylon glass-filled. Substitutes 281698-4 and 281699-4 use thermoplastic material.

Contact Length - Mating: Varies between 0.230" (5.84mm) for the main part, 0.405" (10.29mm) for 0022286043, and 0.276" (7.00mm) for both TE Connectivity parts.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (281698-4 or 281699-4): TE Connectivity HE13/HE14 series parts maintain shrouded 2-wall configuration and friction lock fastening identical to the main part. Both are RoHS compliant with defined operating temperature range (-40°C ~ 100°C). Selection between 281698-4 (tin mating finish) and 281699-4 (gold mating finish) depends on contact finish requirements. These parts offer the highest compatibility with existing designs using the 78208-504.

Secondary Selection (0022286043): The Molex KK254 part is RoHS3 compliant and offers the highest inventory availability (11635 units). This part is suitable when design constraints permit unshrouded configuration and push-pull fastening. The longer mating contact length (0.405" vs. 0.230") and reduced insulation height (0.090" vs. 0.203") require PCB layout verification before implementation.

Compliance Consideration: The main part 78208-504 is RoHS non-compliant. All three substitute parts are RoHS compliant, making them preferable for applications subject to RoHS regulations.

Frequently Asked Questions (FAQ)

Q: Can 0022286043 (Molex) be used as a direct replacement for 78208-504?

A: The Molex 0022286043 shares the critical mating parameters (0.100" pitch, 4-position, male pin, through-hole right-angle, solder termination). However, it differs in shrouding (unshrouded vs. shrouded 2-wall), fastening type (push-pull vs. friction lock), and insulation height (0.090" vs. 0.203"). PCB layout and connector cavity design must be verified for compatibility.

Q: What is the difference between 281698-4 and 281699-4?

A: Both TE Connectivity parts are mechanically and electrically identical. The primary difference is contact finish: 281698-4 uses tin mating finish, while 281699-4 uses gold mating finish. Selection depends on application requirements for contact durability and corrosion resistance.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts (0022286043, 281698-4, 281699-4) are RoHS compliant. The main part 78208-504 is RoHS non-compliant. For applications requiring RoHS compliance, any substitute part is acceptable from a regulatory standpoint.

Q: Does contact length variation affect mating compatibility?

A: Contact length differences (0.230" for 78208-504, 0.405" for 0022286043, 0.276" for TE parts) do not prevent mating with standard 0.100" pitch receptacles. However, contact engagement depth and retention force may vary. Verify mating receptacle specifications for applications with critical contact force requirements.

Q: Which substitute offers the best inventory availability?

A: Molex 0022286043 has the highest inventory level at 11635 units, followed by TE Connectivity 281698-4 at 18102 units. Both exceed the main part inventory of 817 units.

Q: Can I use these parts interchangeably in existing designs?

A: Mechanical and electrical interchangeability depends on design specifics. Shrouding configuration, fastening type, and insulation height differences require design review. TE Connectivity parts (281698-4, 281699-4) offer the closest mechanical match to the original 78208-504. Molex 0022286043 requires design verification due to unshrouded configuration and different fastening mechanism.
