Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector headers is determined by the following critical parameters:

• Pitch (Mating): Must be 0.100" (2.54mm) to ensure mechanical and electrical compatibility with mating connectors and PCB layouts
• Contact Type: Must be Male Pin to maintain proper mating interface
• Mounting Type: Must be Through Hole for PCB assembly compatibility
• Termination: Must be Solder for standard PCB integration
• Connector Style: Board to Board or Board to Board/Cable configurations are acceptable
• Contact Finish: Gold plating on mating surfaces ensures reliable electrical contact
• Current Rating: Must meet or exceed 2.5A for electrical load compatibility
• Operating Temperature Range: Must encompass or exceed -40°C ~ 105°C for thermal environment compatibility
• RoHS Compliance: Preferred for regulatory alignment

The substitute part 4-102972-0 (TE Connectivity AMP Connectors) shares the core electrical and mechanical parameters but differs in position count (40 vs. 11) and product status (Obsolete vs. Active). This part is listed as a manufacturer-recommended substitute based on parameter compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 3M 929705-11-11-I is the primary selection for new designs and active production applications due to its Active product status and RoHS compliance. This part meets current regulatory requirements and maintains full manufacturer support.

The TE Connectivity 4-102972-0 is listed as a manufacturer-recommended substitute based on electrical and mechanical parameter compatibility. However, this part carries an Obsolete product status and is not RoHS compliant. Selection of this substitute should be limited to legacy system maintenance or applications where regulatory compliance is not required. The higher current rating (3A vs. 2.5A) and extended lower operating temperature limit (-65°C vs. -40°C) provide additional margin in specific thermal environments, but these advantages do not offset the obsolescence and compliance limitations for new applications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 4-102972-0 be used as a direct replacement for the 3M 929705-11-11-I?

A: The two parts share compatible electrical and mechanical parameters (pitch, contact type, mounting, termination, and current rating). However, the TE part has 40 positions versus 11 positions on the 3M part. Direct substitution is possible only if the application circuit design accommodates the higher position count or if only 11 positions are populated. The TE part's Obsolete status and lack of RoHS compliance make it unsuitable for new designs.

Q: What are the critical parameters that determine connector header substitutability?

A: The primary parameters are pitch (0.100" / 2.54mm), contact type (Male Pin), mounting method (Through Hole), termination type (Solder), and current rating (minimum 2.5A). These parameters ensure mechanical fit on the PCB and electrical compatibility with mating connectors. Operating temperature range and contact finish also influence long-term reliability.

Q: Does the difference in contact finish thickness affect compatibility?

A: The TE Connectivity part has a thicker gold plating on mating contacts (15.0µin vs. 10.0µin). This provides additional corrosion resistance and contact durability but does not affect mechanical or electrical compatibility. Both finishes meet standard connector performance requirements.

Q: Why is the TE Connectivity part listed as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued production and support. While existing inventory may be available, long-term supply cannot be guaranteed. For production applications, the Active 3M part is the recommended choice.

Q: Are there RoHS compliance implications for using the TE Connectivity substitute?

A: The TE Connectivity 4-102972-0 is marked as "Not applicable" for RoHS status, indicating it does not meet RoHS compliance requirements. Applications subject to RoHS regulations (EU and similar markets) must use the 3M 929705-11-11-I, which is RoHS Compliant.
