Parameter Comparison

Engineering Selection Recommendations

The substitute part 9-146306-0 is the direct equivalent for the obsolete 2-104347-7. Both components share identical mechanical and electrical specifications within the AMPMODU Mod II series, ensuring pin-for-pin and footprint compatibility.

The 9-146306-0 offers the following advantages for new designs and production transitions:

Compliance Status: The substitute part is RoHS compliant, whereas the original part is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulations and environmental compliance requirements.

Material Enhancement: The substitute incorporates glass-filled thermoplastic insulation material, compared to standard thermoplastic in the original part. This provides improved mechanical and thermal stability.

Contact Finish: The substitute uses tin plating on the post termination, replacing the tin-lead finish of the original part. This change aligns with lead-free manufacturing standards.

Documented Performance Parameters: The substitute part includes specified operating temperature range (-65°C ~ 105°C), current rating (3A), and material flammability rating (UL94 V-0), providing complete environmental and performance documentation.

Product Availability: The substitute part maintains active product status with higher inventory availability (1045 pieces in stock versus 681 pieces for the obsolete part).

For applications currently using 2-104347-7, direct substitution with 9-146306-0 is supported across all mechanical, electrical, and functional requirements.

Frequently Asked Questions (FAQ)

Q: Are the 2-104347-7 and 9-146306-0 pin-for-pin compatible?

A: Yes. Both parts maintain identical pin counts (40 positions), pitch (0.100" / 2.54mm), contact geometry, and mounting configuration. PCB footprints are interchangeable.

Q: What is the difference in contact finish between these parts?

A: The original 2-104347-7 uses tin-lead plating on the post termination. The substitute 9-146306-0 uses tin plating. Both maintain gold plating on the mating contact surfaces at 30.0µin thickness. The tin finish on the substitute aligns with lead-free manufacturing standards.

Q: Does the glass-filled thermoplastic insulation in the substitute part affect mechanical fit?

A: No. The insulation height (0.138" / 3.50mm) and overall dimensional specifications remain identical. Glass-filled thermoplastic provides enhanced mechanical strength and thermal stability without changing the connector's physical envelope.

Q: Is the substitute part suitable for applications requiring RoHS compliance?

A: Yes. The 9-146306-0 is RoHS compliant, whereas the original 2-104347-7 is RoHS non-compliant. The substitute part meets RoHS requirements for new designs and production transitions.

Q: What is the operating temperature range for these connectors?

A: The original part does not specify an operating temperature range. The substitute part 9-146306-0 is rated for -65°C ~ 105°C operation.

Q: What is the current rating for these connectors?

A: The original part does not specify a current rating. The substitute part 9-146306-0 is rated for 3A per contact.

Q: Are both parts available in the same packaging?

A: The original 2-104347-7 packaging is not specified. The substitute 9-146306-0 is supplied in bulk packaging.

Q: Can I use the 9-146306-0 as a direct replacement in existing designs?

A: Yes. The substitute part maintains full mechanical and electrical equivalence with the original part. All dimensional, contact, and termination specifications are identical, supporting direct substitution in existing PCB designs and assemblies.
