Substitute Part Grouping Explanation

Substitution of the obsolete 6-173279-3 with the active equivalent 6-5173279-3 is based on strict electrical and mechanical parameter alignment. Both connectors maintain identical specifications across all critical substitution criteria:

Key Parameters Determining Substitution Eligibility:

• Connector type, style, and gender (D-Type, Board to Board, Plug with Female Sockets)
• Position count and row configuration (50 positions, 2 rows)
• Pitch and row-to-row spacing (0.050 Pitch x 0.100 Row to Row)
• Mounting and termination method (Through Hole, Solder)
• Electrical ratings (1A current, 100V voltage)
• Operating temperature range (-55°C to 105°C)
• Contact material and finish specifications (Phosphor Bronze, Gold 30.0µin)
• Flange configuration (Housing/Shell Unthreaded)
• Regulatory compliance (UL94 V-0)
• Moisture sensitivity classification (MSL 1)

The substitute part 6-5173279-3 is manufactured by the same supplier (TE Connectivity AMP Connectors) and belongs to the same AMPLIMITE .050 I series, ensuring form, fit, and functional compatibility with existing designs.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 6-5173279-3 is the direct active equivalent for the obsolete 6-173279-3. Selection of the substitute part is based on the following engineering criteria:

Product Status: The main part 6-173279-3 is classified as obsolete, creating supply chain risk. The substitute 6-5173279-3 maintains active product status with confirmed inventory availability (702 pieces in stock), ensuring long-term component sourcing for production and field replacement applications.

Regulatory Compliance: The substitute part 6-5173279-3 is RoHS compliant, whereas the main part is RoHS non-compliant. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the substitute part satisfies these regulatory obligations without design modification.

Dielectric Material: The substitute part utilizes Polybutylene Terephthalate (PBT) as the dielectric material, compared to the generic thermoplastic specification of the main part. PBT provides enhanced thermal stability and chemical resistance while maintaining all electrical and mechanical performance parameters.

Electrical and Mechanical Compatibility: All critical electrical parameters (current rating, voltage rating, operating temperature range) and mechanical specifications (connector geometry, pitch, mounting method, termination type) are identical between the main part and substitute, ensuring direct form, fit, and function compatibility.

Packaging Consideration: The substitute part is supplied in bulk packaging, which may differ from the original packaging specification. Bulk packaging does not affect connector performance or functionality.

Frequently Asked Questions (FAQ)

Q: Can the 6-5173279-3 be used as a direct replacement for the 6-173279-3 in existing designs?

A: Yes. The 6-5173279-3 is a direct equivalent with identical electrical ratings (1A, 100V), mechanical configuration (50 positions, 0.050 pitch, through-hole solder termination), operating temperature range (-55°C to 105°C), and contact specifications (phosphor bronze with 30.0µin gold finish). No design modifications are required.

Q: What is the difference in dielectric material between the two parts?

A: The main part 6-173279-3 specifies thermoplastic as the dielectric material, while the substitute 6-5173279-3 uses Polybutylene Terephthalate (PBT). Both materials meet the UL94 V-0 flammability rating and maintain identical electrical performance across the specified operating temperature range. PBT offers enhanced thermal and chemical stability.

Q: Why is the main part classified as obsolete?

A: The 6-173279-3 is designated as obsolete by the manufacturer. The active equivalent 6-5173279-3 is available as the current production alternative, ensuring continued component availability and supply chain continuity.

Q: Does the RoHS compliance difference affect compatibility?

A: The substitute part 6-5173279-3 is RoHS compliant, while the main part 6-173279-3 is RoHS non-compliant. For applications or markets requiring RoHS compliance, the substitute part satisfies these regulatory requirements. The RoHS compliance status does not affect electrical or mechanical compatibility; it reflects the material composition and manufacturing process.

Q: Are the connector positions and pitch specifications identical?

A: Yes. Both parts feature 50 positions arranged in 2 rows with 0.050 pitch and 0.100 row-to-row spacing. The shell size and connector layout are identical, ensuring mechanical interchangeability.

Q: What is the current inventory status for each part?

A: The main part 6-173279-3 has 1041 pieces in stock (obsolete status). The substitute part 6-5173279-3 has 702 pieces in stock (active status). For new designs and long-term production, the active substitute part is recommended.

Q: Does the bulk packaging of the substitute part affect performance?

A: No. Packaging type does not affect connector electrical performance, mechanical function, or reliability. Bulk packaging is a supply and logistics consideration only.

Q: Are the contact finish specifications the same?

A: Yes. Both parts feature gold contact finish with 30.0µin (0.76µm) thickness applied to phosphor bronze contacts, ensuring identical electrical conductivity and corrosion resistance.

Q: What is the moisture sensitivity level for both parts?

A: Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly.
