Amphenol ICC 78554-207 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 78554-207 is a through-hole, right-angle rectangular connector header with 7 positions at 0.100" (2.54mm) pitch. This BERGSTIK® II series component is designed for board-to-board applications requiring male pin headers with kinked pin solder termination and push-pull fastening. The part is currently active in production with 903 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the original part becomes unavailable or when design requirements permit alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 78554-207 is determined by strict alignment of the following critical parameters:

• Connector type classification (Header)
• Contact type (Male Pin)
• Mating pitch (0.100" / 2.54mm)
• Position count (7 positions)
• Row configuration (1 row)
• Mounting orientation (Through Hole, Right Angle)
• Termination method (Solder)
• Fastening mechanism (Push-Pull)
• Contact geometry (Square shape)
• Flammability compliance (UL94 V-0)

The identified substitute parts, Molex 0022288071 and Molex 0022288073, satisfy all critical parameters. Both are KK254 series headers with identical pitch, position count, row configuration, and mounting characteristics. Variations in contact finish material and thickness do not preclude substitution, as these represent alternative surface treatments applied to the same base contact geometry and material composition. Both substitute parts maintain UL94 V-0 flammability compliance and MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

Both Molex substitute parts maintain active product status and full compliance with UL94 V-0 flammability requirements and MSL 1 moisture sensitivity specifications. The Molex 0022288073 offers the closest electrical equivalence to the original 78554-207, featuring identical gold contact finish with matching 15.0µin (0.38µm) thickness specification. The Molex 0022288071 provides an alternative with tin contact finish and increased thickness of 100.0µin (2.54µm), suitable for applications where contact finish material substitution is acceptable.

A significant compliance distinction exists: the original 78554-207 is RoHS non-compliant, while both Molex substitutes (0022288071 and 0022288073) are ROHS3 compliant. This difference is material for applications subject to RoHS regulatory requirements. Both substitute parts are REACH unaffected, providing additional regulatory clarity.

Minor dimensional variations exist in contact mating length (0.318" original versus 0.324" substitutes) and insulation height (0.095" original versus 0.098" substitutes). These differences fall within typical connector design tolerances and do not affect functional interchangeability in standard board-to-board applications.

Frequently Asked Questions (FAQ)

Q: Can Molex 0022288071 and 0022288073 be used interchangeably with the Amphenol ICC 78554-207?

A: Both Molex parts satisfy the critical substitution parameters: 7-position, 0.100" pitch, through-hole right-angle headers with male pins, square contacts, push-pull fastening, and UL94 V-0 compliance. The primary difference is contact finish material. Part 0022288073 matches the original gold finish specification, while 0022288071 uses tin finish. Selection depends on application requirements for contact finish material.

Q: What are the key dimensional differences between the original and substitute parts?

A: Contact mating length differs by 0.006" (0.318" original versus 0.324" substitutes), and insulation height differs by 0.003" (0.095" original versus 0.098" substitutes). These variations are within standard connector manufacturing tolerances and do not impact mating compatibility or board-level integration in typical applications.

Q: Does the RoHS compliance difference affect substitution eligibility?

A: The original 78554-207 is RoHS non-compliant, while both Molex substitutes are ROHS3 compliant. This distinction is critical for applications subject to RoHS regulatory requirements. If RoHS compliance is mandatory, only the Molex substitutes are acceptable. If RoHS compliance is not required, this difference does not preclude substitution.

Q: Are there contact finish considerations for substitution?

A: Contact finish material and thickness vary among the three parts. The original specifies gold or gold GXT™ at 15.0µin thickness. Molex 0022288073 matches this specification with gold at 15.0µin. Molex 0022288071 uses tin at 100.0µin thickness. Contact finish affects corrosion resistance and mating force characteristics. Applications with specific contact finish requirements should select the matching part.

Q: What is the inventory status for these parts?

A: The original Amphenol ICC 78554-207 has 903 units in stock. Molex 0022288071 has 1914 units available, and Molex 0022288073 has 2504 units available. Substitute parts offer higher inventory availability.

Q: Are all three parts suitable for automotive, medical, and telecommunications applications?

A: The original 78554-207 does not specify applications. Both Molex substitutes list automotive, general purpose, medical, and telecommunications applications. Application suitability should be confirmed against specific design requirements and regulatory standards for the intended end-use.
