Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3-284489-4 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Connector type (Receptacle)
• Contact type (Female Blade Socket)
• Number of positions (9)
• Pitch (0.197" / 5.00mm)
• Number of rows (1)
• Cable termination method (IDC)
• Contact finish (Tin)

Mechanical Parameters:

• Mounting type (Free Hanging In-Line and Right Angle)
• PCB mating capability

Environmental & Compliance Parameters:

• RoHS compliance status
• Moisture sensitivity level (MSL 1)
• ECCN and HTSUS classifications

The substitute part 1-282049-1 meets all critical electrical and mechanical parameters required for functional equivalence. The primary difference is product status: the main part is obsolete while the substitute is active, making the substitute suitable for new designs and ongoing procurement.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement: The 1-282049-1 is the direct substitute for the 3-284489-4. Both parts share identical electrical and mechanical specifications across all critical parameters: 9-position receptacle configuration, 0.197" pitch, IDC termination, tin contact finish, and PCB mating capability. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

Compliance Considerations: Both parts meet RoHS compliance requirements and carry identical ECCN and HTSUS classifications. The substitute part specifies contact finish thickness (78.7µin / 2.00µm), providing additional documentation for quality assurance purposes. Both parts maintain MSL 1 rating, indicating unlimited moisture sensitivity protection.

Series Transition: The transition from Mark II (3-284489-4) to Mark I (1-282049-1) represents a backward-compatible design evolution within the TE Connectivity AMP Connectors product line. The Mark I series maintains full functional equivalence while offering improved availability and support.

Frequently Asked Questions (FAQ)

Q: Can the 1-282049-1 directly replace the 3-284489-4 in existing applications?

A: Yes. Both parts are 9-position rectangular receptacle connectors with identical pitch (0.197" / 5.00mm), IDC termination, tin contact finish, and mounting configurations. The electrical and mechanical interfaces are fully compatible.

Q: What is the primary reason for substitution?

A: The 3-284489-4 is classified as obsolete, while the 1-282049-1 is an active product. Substitution ensures continued availability and supply chain support for new designs and maintenance applications.

Q: Are there differences in fastening type between the two parts?

A: The 3-284489-4 specifies friction lock fastening. The 1-282049-1 does not specify a fastening type in the provided documentation. Both parts maintain the same mounting type (Free Hanging In-Line and Right Angle), ensuring mechanical compatibility.

Q: Do both parts meet the same compliance standards?

A: Both parts are RoHS compliant and carry identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications. The 3-284489-4 is ROHS3 compliant, while the 1-282049-1 is RoHS compliant. Both maintain MSL 1 rating.

Q: What is the difference in contact finish specification?

A: The 1-282049-1 provides explicit contact finish thickness documentation (78.7µin / 2.00µm), while the 3-284489-4 does not specify this parameter. Both use tin contact finish. The documented thickness on the substitute part provides additional quality assurance information.

Q: Are packaging differences significant for component selection?

A: The 3-284489-4 packaging is not specified in the documentation. The 1-282049-1 is supplied in bulk packaging. Packaging differences do not affect electrical or mechanical compatibility; they relate only to procurement and inventory management.

Q: What is the inventory status for each part?

A: The 3-284489-4 has 902 pieces in stock. The 1-282049-1 has 1069 pieces in stock. Both are available as new original components.
