Key Parameters

Substitute Part Grouping Explanation

Substitution between the main part 146128-2 and the identified substitute 5-146128-2 is based on matching the following critical parameters:

• Connector Type: Header, Breakaway
• Contact Type: Male Pin
• Number of Positions: 4
• Pitch - Mating: 0.100" (2.54mm)
• Mounting Type: Surface Mount
• Termination: Solder
• Insulation Material: Liquid Crystal Polymer (LCP)
• Operating Temperature: -65°C ~ 105°C
• Current Rating: 3A
• Material Flammability Rating: UL94 V-0
• Series: AMPMODU Mod II

The primary difference between these parts is packaging format and compliance status. The substitute part 5-146128-2 is supplied in Tube packaging and carries RoHS Compliant status, whereas the main part 146128-2 is RoHS non-compliant. Both parts share identical electrical and mechanical specifications within the AMPMODU Mod II series.

Parameter Comparison

Engineering Selection Recommendations

Both 146128-2 and 5-146128-2 are Active status products from TE Connectivity within the AMPMODU Mod II series. Selection between these parts is determined by compliance and packaging requirements:

146128-2 is suitable for applications where RoHS compliance is not a requirement and standard packaging is acceptable.

5-146128-2 is the appropriate selection for applications requiring RoHS Compliant components and where Tube packaging is compatible with assembly processes. This part carries RoHS Compliant certification, making it suitable for regulated markets and applications with environmental compliance mandates.

Both parts maintain identical electrical performance, mechanical dimensions, and thermal operating characteristics. The contact finish on the post differs between the two parts: 146128-2 uses Tin-Lead while 5-146128-2 uses Tin. This distinction reflects the RoHS compliance requirement in the substitute part.

Frequently Asked Questions (FAQ)

Q: Are 146128-2 and 5-146128-2 electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including 3A current rating, operating temperature range of -65°C to 105°C, and contact material composition. The mating pitch, contact type, and number of positions are identical.

Q: What is the primary difference between these two parts?

A: The primary differences are packaging format and RoHS compliance status. The 146128-2 is supplied in standard packaging and is RoHS non-compliant. The 5-146128-2 is supplied in Tube packaging and is RoHS Compliant. Additionally, the contact finish on the post differs: Tin-Lead for 146128-2 and Tin for 5-146128-2.

Q: Can I use 5-146128-2 as a direct replacement for 146128-2 in my assembly?

A: Yes, provided your assembly process is compatible with Tube packaging. The mechanical and electrical specifications are identical, allowing direct substitution in the connector interface. Verify that your soldering process is compatible with the Tin contact finish on the post of the 5-146128-2.

Q: Which part should I select for new designs?

A: For new designs, 5-146128-2 is recommended if RoHS compliance is required by your application, market, or regulatory environment. Both parts are Active status and equally suitable for ongoing production.

Q: Does the packaging difference affect the connector performance?

A: No. Packaging format (standard versus Tube) does not affect electrical or mechanical performance. The difference is in supply and handling logistics only.

Q: Are there any temperature or current rating differences between these parts?

A: No. Both parts operate across -65°C to 105°C and are rated for 3A current. All thermal and electrical specifications are identical.

Q: What does RoHS Compliant mean for the 5-146128-2?

A: RoHS Compliant indicates that the 5-146128-2 meets the Restriction of Hazardous Substances directive, which limits the use of specific hazardous materials in electrical and electronic equipment. This is reflected in the Tin contact finish on the post, which replaces the Tin-Lead finish used in the non-compliant 146128-2.
