Substitute Part Grouping Explanation

The substitute part 3-644043-8 is functionally equivalent to the primary part 644043-8 based on the following critical parameters that determine substitution eligibility:

Matching Parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (8)
• Pitch (0.100" / 2.54mm)
• Number of rows (1)
• Mounting type (Free Hanging In-Line, Right Angle)
• Cable termination method (IDC)
• Wire gauge (26 AWG)
• Contact finish (Gold)
• Contact finish thickness (30.0µin / 0.76µm)
• Closed-end design
• Fastening type (Locking Ramp)
• Series designation (MTA-100)

Differing Parameters:

• Packaging format (original part unspecified; substitute in Bulk)
• RoHS certification level (original: RoHS Compliant; substitute: ROHS3 Compliant)
• HTSUS classification (original: 8536.69.8000; substitute: 8536.69.4051)
• REACH status (substitute: REACH Unaffected)

The substitute part maintains identical electrical and mechanical specifications, ensuring direct interchangeability in applications requiring the MTA-100 series 8-position IDC receptacle connector.

Parameter Comparison

Engineering Selection Recommendations

Both the primary part 644043-8 and substitute part 3-644043-8 are active products manufactured by TE Connectivity AMP Connectors and are suitable for direct substitution in applications requiring an 8-position MTA-100 series IDC receptacle connector with 26 AWG wire termination.

Compliance Considerations:

The primary part 644043-8 carries RoHS Compliant certification, while the substitute part 3-644043-8 carries ROHS3 Compliant certification. Both certifications indicate compliance with hazardous substance restrictions. The substitute part additionally carries REACH Unaffected status, indicating compliance with European chemical regulations.

Packaging and Inventory:

The primary part is available in 840 pieces with unspecified packaging. The substitute part is available in 854 pieces in Bulk packaging format. Selection between these parts should be based on packaging requirements and inventory availability for the specific application.

Regulatory Classification:

Both parts are classified under ECCN EAR99 for export control purposes. The HTSUS classifications differ (8536.69.8000 for the primary part and 8536.69.4051 for the substitute), which may affect tariff and customs documentation depending on import/export jurisdiction.

Frequently Asked Questions (FAQ)

Q: Can the 3-644043-8 be used as a direct replacement for the 644043-8?

A: Yes. Both parts are electrically and mechanically identical. They share the same connector type, contact configuration, pitch, termination method, wire gauge, and contact finish specifications. The parts are interchangeable in all applications requiring an 8-position MTA-100 series IDC receptacle connector.

Q: What is the difference between the two part numbers?

A: The primary difference is packaging format. The 644043-8 is supplied in unspecified packaging, while the 3-644043-8 is supplied in Bulk packaging. Additionally, the substitute part carries ROHS3 Compliant and REACH Unaffected certifications, compared to RoHS Compliant for the primary part. Both parts meet the same electrical and mechanical specifications.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. Both parts are manufactured by TE Connectivity AMP Connectors and conform to the MTA-100 series standard. They accept the same IDC termination tooling, mate with identical plug connectors, and support the same 26 AWG wire gauges.

Q: Which part should be selected for new designs?

A: Selection should be based on packaging requirements and regulatory compliance needs. The substitute part 3-644043-8 offers ROHS3 and REACH compliance certifications, which may be advantageous for applications subject to European regulatory requirements. Both parts are active products with adequate inventory availability.

Q: What is the significance of the contact finish thickness specification?

A: The 30.0µin (0.76µm) gold plating thickness ensures consistent electrical contact resistance and corrosion protection across both parts. This specification is identical for both the primary and substitute parts, confirming equivalent performance in high-reliability applications.

Q: Can these connectors be used with both discrete and ribbon cable?

A: Yes. Both parts support IDC termination with discrete or ribbon cable in 26 AWG gauge. The IDC termination method allows direct connection without stripping or soldering, accommodating both cable types within the specified wire gauge range.
