Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 146425-5 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Header, Breakaway
• Contact Type: Male Pin
• Number of Positions: 7
• Number of Rows: 1
• Pitch - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Shrouding: Unshrouded
• Contact Shape: Square
• Contact Finish - Mating: Gold
• Contact Finish - Post: Tin-Lead
• Insulation Material: Thermoplastic
• Insulation Color: Black
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations:

• Contact Material: Phosphor Bronze or Copper Alloy
• Contact Finish Thickness - Mating: 5.00µin (0.127µm) to 30.0µin (0.76µm)
• Operating Temperature: Specified or unspecified
• Current Rating: Specified or unspecified
• RoHS Status: Compliant or non-compliant
• Product Status: Obsolete, Discontinued, or Active

The substitute part 4-103747-0-07 meets all mandatory matching parameters and falls within allowable variations for contact material and finish thickness specifications.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 4-103747-0-07 is electrically and mechanically equivalent to the 146425-5 across all critical connector parameters. Both components are from the same AMPMODU Mod II series and share identical pitch, position count, contact configuration, and mounting characteristics.

Compliance Considerations:

The primary distinction between the two parts is RoHS compliance status. The main part 146425-5 is RoHS Compliant, while the substitute 4-103747-0-07 is RoHS non-compliant. Applications subject to RoHS regulations (EU Directive 2011/65/EU and amendments) require the compliant variant. Applications without RoHS requirements may use either part.

Contact Material Variation:

The substitute part uses Copper Alloy contact material compared to Phosphor Bronze in the main part. Both materials are suitable for the specified connector class and provide equivalent electrical performance in this application context.

Contact Finish Thickness:

The substitute part specifies a higher gold plating thickness (30.0µin versus 5.00µin on the mating surface). This represents an enhancement in contact durability and wear resistance, with no negative impact on compatibility.

Operational Specifications:

The substitute part provides explicit operating temperature range (-65°C ~ 105°C) and current rating (3A), whereas the main part does not specify these parameters. These specifications define the operational envelope for the substitute component.

Frequently Asked Questions (FAQ)

Q: Are the 146425-5 and 4-103747-0-07 mechanically interchangeable?

A: Yes. Both connectors share identical pitch (0.100"), position count (7), row configuration (1 row), mounting type (through hole), and overall contact geometry. They are mechanically interchangeable in board-level applications.

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

A: The 146425-5 uses Phosphor Bronze contacts, while the 4-103747-0-07 uses Copper Alloy contacts. Both materials provide equivalent electrical conductivity and contact performance for this connector class. The material difference does not affect functional compatibility.

Q: Why does the substitute part have a higher gold plating thickness?

A: The 4-103747-0-07 specifies 30.0µin (0.76µm) gold plating on mating surfaces compared to 5.00µin (0.127µm) on the 146425-5. Increased plating thickness enhances contact durability and extends service life under repeated mating cycles. This represents a specification enhancement with no compatibility impact.

Q: Can I use the 4-103747-0-07 in applications requiring RoHS compliance?

A: No. The 4-103747-0-07 is RoHS non-compliant. Applications subject to RoHS regulations must use the 146425-5 or other RoHS-compliant alternatives. Verify regulatory requirements for your specific application before component selection.

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

A: The 146425-5 does not specify an operating temperature range. The 4-103747-0-07 specifies -65°C ~ 105°C. For applications requiring defined thermal performance, the 4-103747-0-07 provides explicit operational limits. Consult application requirements to determine if temperature specification is necessary.

Q: What current rating applies to these connectors?

A: The 146425-5 does not specify a current rating. The 4-103747-0-07 specifies 3A per contact. For applications requiring defined current capacity, the 4-103747-0-07 provides explicit current limits. Consult application requirements to determine if current specification is necessary.

Q: Are both parts available in the same packaging?

A: The 146425-5 packaging is not specified in available documentation. The 4-103747-0-07 is supplied in Bulk packaging. Verify packaging requirements with your procurement process.

Q: What is the moisture sensitivity level for these connectors?

A: Both the 146425-5 and 4-103747-0-07 are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors do not require special moisture control during storage or handling.
