Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 1-103639-3 is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Connector type (Header)
• Number of positions (14)
• Pitch specification (0.100" / 2.54mm)
• Row configuration (1 row)
• Mounting method (Through Hole)
• Contact gender (Male Pin)
• Shrouding design (Shrouded - 4 Wall)
• Current rating (3A)
• Operating temperature range (-65°C ~ 105°C)

Important Matching Parameters:

• Series designation (AMPMODU MTE)
• Contact finish material (Tin-Lead or Tin)
• Flammability rating (UL94 V-0)
• Insulation material (Thermoplastic)
• Contact material (Brass)

The substitute part 6-103639-3 meets all critical and important parameters. The primary difference is the contact finish specification: the main part uses Tin-Lead finish while the substitute uses Tin finish. Both finishes are applied at identical thickness (100.0µin / 2.54µm) and provide equivalent electrical and mechanical performance within the specified operating parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 6-103639-3

The 6-103639-3 is a direct functional equivalent to the 1-103639-3 across all critical electrical and mechanical parameters. Both connectors are manufactured by TE Connectivity within the AMPMODU MTE series and maintain identical specifications for pitch, position count, current rating, temperature range, and physical dimensions.

Compliance Consideration:

The substitute part 6-103639-3 carries RoHS Compliant status, whereas the main part 1-103639-3 is RoHS non-compliant. This distinction is significant for applications subject to RoHS directives. The contact finish difference (Tin versus Tin-Lead) is the technical basis for the RoHS compliance status of the substitute part. Both finishes are applied at identical thickness and provide equivalent electrical performance within the specified operating parameters.

Inventory Status:

The substitute part 6-103639-3 maintains higher stock availability (2512 pieces) compared to the main part (782 pieces), both supplied in tube packaging and with Active product status.

Selection Basis:

• Use 1-103639-3 when RoHS non-compliant specifications are explicitly required or when tin-lead contact finish is mandated by design requirements.
• Use 6-103639-3 when RoHS compliance is required or preferred, or when higher inventory availability is advantageous.

Both parts are suitable for automotive, general purpose, medical, and telecommunications applications within the specified operating temperature range of -65°C to 105°C.

Frequently Asked Questions (FAQ)

Q: Are the 1-103639-3 and 6-103639-3 interchangeable in all applications?

A: Both connectors are functionally equivalent across all critical electrical and mechanical parameters including pitch, position count, current rating, temperature range, and physical dimensions. The primary difference is the contact finish material (tin-lead versus tin) and RoHS compliance status. Interchangeability depends on whether the application has specific requirements for contact finish material or regulatory compliance. Consult application documentation for finish material specifications.

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

A: The main part 1-103639-3 uses tin-lead contact finish, while the substitute 6-103639-3 uses tin finish. Both are applied at identical thickness (100.0µin / 2.54µm). The tin finish in the substitute part is the basis for its RoHS Compliant status. From an electrical and mechanical standpoint, both finishes provide equivalent performance within the specified operating parameters of 3A current rating and -65°C to 105°C temperature range.

Q: Why does the substitute part have RoHS Compliant status while the main part does not?

A: RoHS compliance is determined by the absence of restricted substances including lead. The main part 1-103639-3 uses tin-lead contact finish, which contains lead and results in RoHS non-compliant status. The substitute part 6-103639-3 uses tin contact finish without lead, achieving RoHS Compliant status. Both parts are otherwise identical in design and function.

Q: Are there any performance differences between tin-lead and tin contact finishes in this connector?

A: Both contact finishes are applied at identical thickness and provide equivalent electrical conductivity and mechanical durability within the specified operating parameters. The choice between tin-lead and tin finish is primarily driven by regulatory compliance requirements rather than performance differences in this application.

Q: Can I use the 6-103639-3 as a direct replacement for the 1-103639-3 in existing designs?

A: Yes, the 6-103639-3 is a direct functional replacement for the 1-103639-3. All critical parameters including connector type, position count, pitch, mounting method, current rating, and operating temperature are identical. The substitute part maintains the same physical footprint and electrical characteristics. Verify that your application does not have explicit requirements for tin-lead contact finish or RoHS non-compliant status before substitution.

Q: What is the packaging format for both parts?

A: Both the 1-103639-3 and 6-103639-3 are supplied in tube packaging. This packaging format is standard for through-hole connector headers and is suitable for both manual and automated assembly processes.

Q: Are both parts suitable for medical applications?

A: Yes, both the 1-103639-3 and 6-103639-3 are listed for medical applications. Both connectors carry UL94 V-0 material flammability rating and operate across the temperature range of -65°C to 105°C, meeting requirements for medical device applications. Verify specific medical device regulatory requirements for your application.

Q: What is the current rating for these connectors?

A: Both connectors are rated for 3A continuous current. This rating applies to each individual contact within the 14-position header. Ensure that your application current requirements do not exceed this specification.

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

A: Both connectors operate across a temperature range of -65°C to 105°C. This range covers typical industrial, automotive, medical, and telecommunications applications. Verify that your application environment falls within this specification.
