Substitute Part Grouping Explanation

Substitution of the 9-146291-0 is based on electrical and mechanical compatibility within the AMPMODU Mod II series. The substitute part 9-146278-0 shares the following critical parameters that establish functional equivalence:

• Identical connector type (Header, Breakaway)
• Identical number of positions (40)
• Identical pitch spacing (0.100" / 2.54mm)
• Identical contact type (Male Pin)
• Identical mounting method (Through Hole)
• Identical row configuration (1 row)
• Identical operating temperature range (-65°C ~ 105°C)
• Identical current rating (3A)
• Identical insulation material (Liquid Crystal Polymer)
• Identical flammability rating (UL94 V-0)

The primary difference between these parts is the termination method and contact finish specifications. The 9-146291-0 features kinked pin termination with gold mating contact finish, while the 9-146278-0 features standard solder termination with tin mating contact finish. Both parts maintain electrical and mechanical compatibility for standard through-hole PCB applications.

Parameter Comparison

Engineering Selection Recommendations

The 9-146278-0 serves as the active production equivalent for the obsolete 9-146291-0. Selection between these parts is determined by application requirements and product lifecycle status.

For new designs and active production: The 9-146278-0 is the appropriate selection. This part maintains active product status with TE Connectivity, ensuring ongoing availability and supply chain support. The part is ROHS3 compliant, meeting current regulatory requirements. Inventory availability is higher (1072 pieces) compared to the main part.

For legacy system maintenance and repair: The 9-146291-0 remains suitable where existing designs are locked to this specific part number. However, the 9-146278-0 provides functional equivalence for applications where component substitution is permissible.

Contact finish consideration: The primary technical difference is the mating contact finish. The 9-146291-0 features gold plating (5.00µin thickness), while the 9-146278-0 features tin plating (100.0µin thickness). Both finishes are suitable for standard through-hole PCB applications with equivalent electrical performance. The gold finish on the main part provides enhanced corrosion resistance in high-humidity or corrosive environments; the tin finish on the substitute part is standard for general-purpose applications.

Termination method: The 9-146291-0 specifies kinked pin termination, while the 9-146278-0 specifies standard solder termination. Both methods are compatible with through-hole PCB assembly processes. The kinked pin design on the main part provides mechanical retention during PCB insertion; the standard solder termination on the substitute part is the current manufacturing standard.

Compliance status: Both parts meet UL94 V-0 flammability requirements and maintain unlimited moisture sensitivity (MSL 1). The 9-146278-0 carries ROHS3 compliance, representing the current regulatory standard.

Frequently Asked Questions (FAQ)

Q: Can the 9-146278-0 directly replace the 9-146291-0 in existing PCB designs?

A: Yes. Both parts share identical electrical and mechanical specifications for connector type, position count, pitch spacing, contact type, mounting method, operating temperature range, and current rating. The parts are functionally equivalent for through-hole PCB applications. The difference in contact finish (gold versus tin) and termination method (kinked pin versus standard solder) does not affect electrical compatibility or mechanical fit.

Q: What is the significance of the kinked pin termination on the 9-146291-0?

A: Kinked pin termination provides mechanical retention of the connector during PCB insertion and wave soldering processes. The 9-146278-0 uses standard solder termination, which is the current manufacturing standard and provides equivalent mechanical stability through solder joint formation. Both termination methods are suitable for production PCB assembly.

Q: Does the gold contact finish on the 9-146291-0 provide superior performance compared to the tin finish on the 9-146278-0?

A: Gold plating provides enhanced corrosion resistance in high-humidity or chemically aggressive environments. Tin plating is suitable for standard indoor and controlled environment applications. Selection between these finishes depends on the specific operating environment. For general-purpose applications, both finishes deliver equivalent electrical performance.

Q: Why is the 9-146291-0 classified as obsolete?

A: The 9-146291-0 has been superseded by the 9-146278-0 in TE Connectivity's active product portfolio. The substitute part incorporates current manufacturing standards and regulatory compliance (ROHS3). Existing inventory of the main part remains available for legacy system support.

Q: Are there packaging differences between these parts?

A: The 9-146291-0 is listed with unspecified packaging, while the 9-146278-0 is packaged in bulk. Both parts are identical in form, fit, and function. Packaging differences do not affect electrical or mechanical compatibility.

Q: What is the current availability status of these parts?

A: The 9-146291-0 has 732 pieces in stock (new original). The 9-146278-0 has 1072 pieces in stock (new original). The substitute part offers higher inventory availability and active production status.

Q: Are both parts RoHS compliant?

A: Yes. The 9-146291-0 is RoHS compliant. The 9-146278-0 is ROHS3 compliant, representing the current regulatory standard. Both parts meet RoHS requirements for restricted substance elimination.
