• Row Spacing - Mating: 0.100" (2.54mm)
• Contact Type: Male Pin
• Current Rating: 3A
• Operating Temperature Range: -65°C ~ 105°C

Mechanical Compatibility:

• Connector Type: Header, Breakaway
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Shape: Square
• Insulation Material: Liquid Crystal Polymer (LCP)
• Insulation Height: 0.090" (2.29mm)
• Contact Length - Mating: 0.230" (5.84mm)
• Contact Length - Post: 0.090" (2.29mm)
• Overall Contact Length: 0.410" (10.41mm)

Regulatory Compliance:

• Material Flammability Rating: UL94 V-0
• RoHS Compliance: Required
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part 9-146258-0 maintains full equivalence across all electrical and mechanical parameters. The primary distinction is product status: the original part is obsolete, while the substitute is active and available in higher inventory quantities.

Parameter Comparison

Engineering Selection Recommendations

The 9-146258-0 is the direct active equivalent for the obsolete 4-146258-0. Both parts are manufactured by TE Connectivity AMP Connectors within the AMPMODU Mod II series and maintain identical electrical and mechanical specifications across all critical parameters.

Product Status Consideration: The original part 4-146258-0 carries an obsolete status, indicating discontinued production and limited long-term availability. The substitute 9-146258-0 maintains active product status with significantly higher inventory levels (5415 units versus 915 units), ensuring supply chain continuity for new designs and production requirements.

Compliance and Certification: Both parts maintain identical regulatory compliance profiles:

• RoHS Compliant
• UL94 V-0 Material Flammability Rating
• Moisture Sensitivity Level 1 (Unlimited)
• ECCN EAR99 classification
• HTSUS 8536.69.4040 tariff code

Contact Finish Distinction: The primary technical difference between the two parts is the contact finish composition. The original part features Tin-Lead plating, while the substitute features Tin plating. Both maintain identical finish thickness specifications of 100.0µin (2.54µm) on both mating and post contacts. This distinction reflects industry-wide transition toward lead-free manufacturing practices while maintaining equivalent electrical and mechanical performance.

Packaging Configuration: The substitute part is supplied in bulk packaging, whereas the original part packaging specification is not provided. This packaging difference does not affect functional compatibility or performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 9-146258-0 be used as a direct replacement for the 4-146258-0 in existing designs?

A: Yes. The 9-146258-0 maintains full electrical and mechanical equivalence with the 4-146258-0 across all critical parameters including position count, pitch, row spacing, contact type, mounting configuration, and operating temperature range. The parts are functionally interchangeable.

Q: What is the significance of the different part number prefix (4- versus 9-)?

A: The prefix difference reflects TE Connectivity's internal product numbering system. The base number 146258 remains identical, indicating the same connector design within the AMPMODU Mod II series. The prefix change corresponds to the transition from obsolete to active product status and associated manufacturing updates.

Q: How does the contact finish difference affect performance?

A: Both Tin-Lead and Tin finishes provide equivalent electrical conductivity and mechanical durability at the specified finish thickness of 100.0µin (2.54µm). The transition to Tin plating reflects industry compliance with lead-free manufacturing standards while maintaining performance specifications. Both finishes support the 3A current rating and -65°C to 105°C operating temperature range.

Q: Are there any compatibility issues with existing mating connectors?

A: No. The 9-146258-0 maintains identical mating specifications including 0.100" (2.54mm) pitch, 0.100" (2.54mm) row spacing, square contact shape, and 0.230" (5.84mm) mating contact length. Existing mating connectors designed for the 4-146258-0 are fully compatible with the 9-146258-0.

Q: What is the difference in packaging between the two parts?

A: The original part 4-146258-0 packaging specification is not provided in the technical documentation. The substitute part 9-146258-0 is supplied in bulk packaging. This packaging difference does not affect connector performance, electrical characteristics, or mechanical compatibility.

Q: Why should the 9-146258-0 be selected for new designs?

A: The 9-146258-0 should be selected for new designs because it maintains active product status with established supply chain availability. The original part 4-146258-0 is obsolete, which limits long-term procurement options and increases supply risk. The substitute part provides equivalent functionality with superior inventory availability (5415 units in stock versus 915 units).

Q: Are both parts RoHS compliant?

A: Yes. Both the 4-146258-0 and 9-146258-0 are RoHS Compliant with identical UL94 V-0 material flammability ratings and Moisture Sensitivity Level 1 (Unlimited) specifications.

Q: What is the current rating for these connectors?

A: Both parts support a current rating of 3A per contact position, with identical operating temperature specifications of -65°C to 105°C.
