Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 87543-7 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 14
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Shrouding: Unshrouded

The substitute part Amphenol ICC (FCI) 67998-414HLF satisfies all mandatory matching parameters. Both components are unshrouded, two-row headers with identical pitch spacing and position count, enabling direct functional substitution in applications requiring through-hole solder termination with push-pull fastening.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol ICC (FCI) 67998-414HLF connector is a direct functional equivalent to the obsolete TE Connectivity 87543-7. Selection of this substitute is supported by the following engineering criteria:

Functional Equivalence: Both connectors maintain identical mating pitch (0.100"), row spacing (0.100"), position count (14 in 2 rows), and contact geometry. Through-hole solder termination and push-pull fastening mechanisms are identical, ensuring compatibility with existing printed circuit board layouts and mating connector designs.

Product Status: The substitute part is classified as Active, ensuring continued availability and supply chain stability. The original part's obsolete status creates supply risk and justifies transition to the active equivalent.

Compliance Improvement: The substitute part is RoHS Compliant, whereas the original part is RoHS non-compliant. This represents an improvement in regulatory compliance for new designs and manufacturing processes subject to RoHS requirements.

Contact Finish: The original part features Tin-Lead finish, while the substitute features Tin finish. Both finishes are compatible with standard solder reflow processes and provide equivalent electrical performance for the specified application.

Mechanical Compatibility: Minor variations in contact length post (0.125" versus 0.107") and overall contact length (0.533" versus 0.525") do not affect functional compatibility, as both dimensions remain within acceptable ranges for standard through-hole PCB mounting and mating connector engagement.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 67998-414HLF directly replace the TE Connectivity 87543-7 in existing designs?

A: Yes. Both connectors share identical mating pitch, row spacing, position count, and contact geometry. The substitute part is compatible with existing PCB layouts and mating connectors designed for the original part.

Q: What is the significance of the contact finish difference (Tin-Lead versus Tin)?

A: Both finishes are compatible with standard solder reflow processes and provide equivalent electrical performance. The Tin finish on the substitute part aligns with modern manufacturing practices and RoHS compliance requirements.

Q: Does the RoHS compliance status of the substitute part affect compatibility?

A: No. RoHS compliance is a regulatory and manufacturing requirement, not a functional parameter. The substitute part's RoHS Compliant status represents an improvement for applications subject to RoHS regulations.

Q: Are there dimensional differences between the two connectors?

A: Minor variations exist in contact post length and overall contact length. The original part has a contact post length of 0.125" (3.18mm) and overall contact length of 0.533" (13.55mm), while the substitute has a contact post length of 0.107" (2.71mm) and overall contact length of 0.525" (13.34mm). These variations do not affect functional compatibility with standard through-hole PCB mounting.

Q: What is the packaging difference between the two parts?

A: The original part packaging is not specified in available documentation. The substitute part is supplied in Bulk packaging. Packaging format does not affect functional compatibility.

Q: Is the insulation material specification different between the two parts?

A: The original part specifies Polyamide (PA), Nylon, Glass Filled insulation material. The substitute part's insulation material is not specified in available documentation. Both parts feature identical Black insulation color and equivalent electrical properties.

Q: What is the current and voltage rating for these connectors?

A: The original part does not specify current or voltage ratings in available documentation. The substitute part is rated for 5A at 110V, providing reference specifications for the connector series.
