Substitute Part Grouping Explanation

Substitution between the main part 3-176264-9 and the equivalent part 3-5176264-9 is based on strict electrical and mechanical parameter alignment. Both components share identical specifications across all critical functional parameters: connector type (Header, Breakaway), contact type (Male Pin), position count (50), row configuration (2 rows), mating pitch (2.00mm), row spacing (2.00mm), mounting method (Through Hole), termination type (Solder), mating contact finish (Gold), operating temperature range (-40°C ~ 105°C), voltage rating (200VAC), and flammability rating (UL94 V-0).

The primary distinction between these parts is product status and compliance posture. The original part 3-176264-9 carries obsolete status with RoHS non-compliant classification, while the substitute 3-5176264-9 maintains active product status with RoHS compliant certification. The substitute also features improved packaging (Tray) and significantly higher inventory availability (7455 units versus 1101 units).

A secondary difference exists in the contact finish for the post termination: the original part specifies Tin-Lead finish, while the substitute specifies Tin finish. This distinction reflects modern compliance requirements and does not affect functional compatibility for the specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 3-5176264-9 is the direct equivalent for the obsolete 3-176264-9. Selection of the substitute part is supported by the following engineering criteria:

Product Status: The substitute maintains active product status, ensuring continued availability and manufacturer support. The original part's obsolete classification indicates discontinued production and potential supply constraints.

Regulatory Compliance: The substitute part carries RoHS compliant certification, meeting current regulatory requirements for electronic components in most jurisdictions. The original part's RoHS non-compliant status presents compliance risk for new designs and applications subject to RoHS directives.

Functional Equivalence: All electrical and mechanical parameters remain identical between the main part and substitute, including connector type, contact configuration, pitch specifications, mounting method, operating temperature range, voltage rating, and flammability rating. This ensures direct functional compatibility in existing circuit designs and PCB layouts.

Contact Finish Specification: The substitute part specifies Tin finish for post termination in place of the original Tin-Lead finish. This change aligns with modern lead-free manufacturing standards and does not affect electrical performance or mechanical compatibility.

Supply Availability: The substitute part demonstrates significantly higher inventory availability (7455 units) compared to the original part (1101 units), supporting production continuity and reducing procurement risk.

For new designs, production runs, and component replenishment, the substitute part 3-5176264-9 is the appropriate selection. For legacy systems requiring exact historical component matching, the original part 3-176264-9 remains available in limited quantities.

Frequently Asked Questions (FAQ)

Q: Are the 3-176264-9 and 3-5176264-9 connectors mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including pitch (2.00mm), row spacing (2.00mm), contact length dimensions, insulation height, and overall form factor. They mount identically on PCBs using the same through-hole solder termination method.

Q: What is the functional difference between these two parts?

A: There is no functional difference in electrical or mechanical performance. Both parts operate across the same temperature range (-40°C ~ 105°C), support the same voltage rating (200VAC), and provide identical contact configuration and contact finish for mating surfaces (Gold plated).

Q: Why does the substitute part specify Tin finish instead of Tin-Lead for the post termination?

A: The Tin finish specification reflects current manufacturing standards and regulatory compliance with lead-free requirements. This change does not affect electrical conductivity, solder joint reliability, or mechanical performance of the connector.

Q: Is the substitute part RoHS compliant?

A: Yes. The substitute part 3-5176264-9 carries RoHS compliant certification. The original part 3-176264-9 is RoHS non-compliant. For applications subject to RoHS directives, the substitute part is required.

Q: What is the difference in packaging between these parts?

A: The original part 3-176264-9 does not specify packaging format. The substitute part 3-5176264-9 is supplied in Tray packaging, which is standard for high-volume production and automated assembly processes.

Q: Can I use the substitute part in existing designs without PCB modification?

A: Yes. The substitute part maintains identical electrical and mechanical specifications, requiring no PCB layout changes, no design modifications, and no assembly process adjustments.

Q: Why is the original part classified as obsolete?

A: Obsolete classification indicates the manufacturer has discontinued production of part 3-176264-9. The substitute part 3-5176264-9 represents the current active equivalent in the AMPMODU series.

Q: What is the inventory status for each part?

A: The original part 3-176264-9 has 1101 units in stock. The substitute part 3-5176264-9 has 7455 units in stock, providing significantly higher availability for production requirements.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both parts operate across the identical temperature range of -40°C to 105°C, supporting the same thermal performance specifications.

Q: What certifications apply to both parts?

A: Both parts carry UL94 V-0 material flammability rating and MSL 1 (Unlimited) moisture sensitivity level. The substitute part adds RoHS compliant certification. Both parts are classified under ECCN EAR99 and HTSUS 8536.69.4040.
