Key Parameters

Substitute Part Grouping Explanation

Substitution for the 72902-272LF is determined by the following critical parameters:

• Connector Configuration: 96-position receptacle with female sockets
• Pitch and Row Structure: 0.100" (2.54mm) pitch with 3-row arrangement
• Mounting and Termination: Through-hole PCB mounting capability
• Contact Material: Gold plating for electrical reliability
• Insulation Material: PBT-based construction for mechanical stability

The identified substitute, TE Connectivity AMP Connectors part number 1-1393642-6, satisfies all critical substitution criteria. This part maintains identical position count, pitch, row configuration, and mounting methodology while offering enhanced specifications in product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 1-1393642-6 substitute from TE Connectivity AMP Connectors is suitable for applications requiring replacement of the obsolete 72902-272LF. The substitute maintains mechanical and electrical compatibility through identical position count, pitch, row configuration, and through-hole mounting architecture.

The substitute offers improved product lifecycle status as an active component with established supply chain availability. The part carries ROHS3 compliance and UL94 V-0 flammability certification, providing enhanced regulatory alignment for modern applications. Operating temperature specification of -55°C ~ 125°C is documented for the substitute, whereas the original part does not provide this parameter.

Termination method differs between the two parts: the original uses solder termination while the substitute specifies wire wrap termination. This difference requires evaluation against specific PCB assembly processes and design requirements.

Frequently Asked Questions (FAQ)

Q: Are the 72902-272LF and 1-1393642-6 mechanically interchangeable?

A: Both connectors share identical 96-position configuration, 0.100" (2.54mm) pitch, 3-row structure, and through-hole mounting. Mechanical interchangeability is established through these common parameters.

Q: What is the significance of the termination method difference?

A: The original part specifies solder termination while the substitute uses wire wrap termination. The selection between these methods depends on the PCB assembly process and design specifications of the target application. Compatibility must be confirmed against the specific assembly methodology.

Q: Does the substitute provide better environmental performance?

A: The substitute includes documented operating temperature range (-55°C ~ 125°C), UL94 V-0 flammability rating, and ROHS3 compliance. The original part does not provide these specifications. Environmental performance comparison requires evaluation against specific application requirements.

Q: What is the difference between gold and gold-palladium contact finish?

A: The substitute offers either gold or gold-palladium contact finish options. Both finishes provide electrical reliability and corrosion resistance. Selection between these options depends on specific application requirements and supplier availability.

Q: Is the substitute available in production quantities?

A: The 1-1393642-6 is classified as an active product with documented inventory availability, providing established supply chain access compared to the obsolete original part.
