Parameter Comparison

Engineering Selection Recommendations

The 9-146285-0 serves as the direct functional equivalent to the obsolete 4-146297-0. Selection of the substitute part is supported by the following engineering factors:

Product Status Consideration: The 4-146297-0 is classified as obsolete, creating supply chain risk for new designs and ongoing production. The 9-146285-0 maintains active product status, ensuring long-term availability and manufacturing support.

Compliance Enhancement: The substitute part 9-146285-0 achieves RoHS compliance and REACH unaffected status, whereas the main part carries RoHS non-compliance and REACH affected designations. This compliance improvement aligns with current regulatory requirements for electronic components in most markets.

Electrical and Mechanical Equivalence: Both parts maintain identical specifications across all critical electrical parameters (40 positions, 2.54mm pitch, 3A current rating, -65°C to 105°C operating range) and mechanical parameters (through-hole mounting, square contact shape, LCP insulation, UL94 V-0 rating).

Termination Compatibility: The substitute employs standard solder termination versus the kinked pin solder termination of the main part. Both termination methods are compatible with standard PCB assembly processes and provide equivalent electrical performance.

Contact Finish Improvement: The substitute utilizes tin finish on the post versus tin-lead finish on the main part. Tin finish represents the lead-free equivalent and is compatible with modern soldering processes.

Frequently Asked Questions (FAQ)

Q: Can the 9-146285-0 be used as a direct replacement for the 4-146297-0 in existing designs?

A: Yes. The 9-146285-0 maintains identical electrical and mechanical specifications across all critical parameters including pitch, position count, contact type, current rating, and operating temperature range. PCB footprints and mating connector interfaces are fully compatible.

Q: What is the difference between kinked pin and standard solder termination?

A: Kinked pin termination features a bent contact post designed for specific insertion angles during assembly. Standard solder termination uses a straight contact post. Both methods provide equivalent electrical performance and are compatible with standard PCB soldering processes. The substitute's standard termination is compatible with conventional assembly equipment.

Q: Does the change from tin-lead to tin finish affect soldering or reliability?

A: No. Tin finish is the lead-free equivalent of tin-lead finish and is compatible with modern lead-free soldering processes. Both finishes provide equivalent electrical conductivity and contact reliability. The tin finish on the substitute part aligns with current RoHS compliance requirements.

Q: Why does the substitute part have different RoHS and REACH status?

A: The 9-146285-0 was manufactured to meet current regulatory requirements, achieving RoHS compliance and REACH unaffected status. The 4-146297-0 predates these regulatory updates. The substitute part's improved compliance status makes it suitable for applications requiring adherence to current environmental and chemical regulations.

Q: Are there any packaging differences between the main part and substitute?

A: The main part 4-146297-0 has unspecified packaging, while the substitute 9-146285-0 is supplied in bulk packaging. Both parts are identical in form, fit, and function. Packaging differences do not affect component performance or compatibility.

Q: What is the inventory status for each part?

A: The main part 4-146297-0 has 632 pieces in stock. The substitute part 9-146285-0 has 3,276 pieces in stock. The substitute's higher inventory level reflects its active product status and ongoing market demand.

Q: Are both parts from the same manufacturer and series?

A: Yes. Both parts are manufactured by TE Connectivity AMP Connectors and belong to the AMPMODU Mod II series. They share the same connector platform and design heritage, ensuring full compatibility.
