Key Parameters

Substitute Part Grouping Explanation

The substitute part 5-103669-7 maintains full electrical and mechanical compatibility with the main part 103669-7 based on the following critical parameters:

Matching Parameters:

• Connector type, contact type, and position count (8-position, 1-row header)
• Pitch specification (0.100" / 2.54mm mating pitch)
• Mounting configuration (through-hole, shrouded 4-wall design)
• Termination method (press-fit and solder capable)
• Current rating (3A)
• Operating temperature range (-65°C ~ 105°C)
• Contact material (brass)
• Insulation material (thermoplastic)
• Flammability rating (UL94 V-0)
• Physical dimensions (contact lengths, insulation height, overall contact length)

Distinguishing Parameter:

• Contact finish specification: 103669-7 uses Tin-Lead finish; 5-103669-7 uses Tin finish
• Compliance status: 5-103669-7 carries RoHS Compliant certification; 103669-7 is Not applicable for RoHS

The substitution is valid where contact finish material and RoHS compliance requirements align with application specifications.

Parameter Comparison

Engineering Selection Recommendations

Part 103669-7 Selection Criteria:

• Applications requiring Tin-Lead contact finish specifications
• Designs where RoHS compliance is not a requirement
• Legacy system compatibility or existing design specifications calling for Tin-Lead plating

Part 5-103669-7 Selection Criteria:

• Applications subject to RoHS Directive compliance requirements
• New designs or design revisions incorporating lead-free component specifications
• Supply chain scenarios where higher inventory availability (2020 units) supports procurement timelines
• Tin contact finish compatibility with mating connector specifications

Both parts maintain identical electrical performance, mechanical dimensions, and thermal operating characteristics. Selection between these parts depends on compliance framework requirements and contact finish material specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Are 103669-7 and 5-103669-7 electrically interchangeable?

A: Yes. Both parts deliver identical electrical performance with 3A current rating, matching contact materials (brass), and equivalent operating temperature ranges (-65°C ~ 105°C). The primary distinction is contact finish material: Tin-Lead versus Tin.

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

A: The 103669-7 features Tin-Lead finish while 5-103669-7 uses Tin finish. Both finishes provide equivalent contact thickness (100.0µin / 2.54µm) and corrosion resistance. The Tin finish in 5-103669-7 aligns with RoHS Compliant requirements, whereas 103669-7 is not RoHS applicable.

Q: Can I substitute 5-103669-7 for 103669-7 in existing designs?

A: Substitution is valid when the application permits Tin contact finish and does not require Tin-Lead specifications. Verify mating connector compatibility with Tin finish contacts and confirm RoHS compliance is acceptable or required for the target application.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical dimensions: 0.100" (2.54mm) mating pitch, 0.230" (5.84mm) contact mating length, 0.130" (3.30mm) post length, 0.545" (13.84mm) overall contact length, and 0.535" (13.60mm) insulation height. Mechanical fit and board layout compatibility are equivalent.

Q: What is the packaging configuration for both parts?

A: Both 103669-7 and 5-103669-7 are supplied in tube packaging. Current inventory shows 1097 units for 103669-7 and 2020 units for 5-103669-7.

Q: Do both parts support the same mounting and termination methods?

A: Yes. Both parts support through-hole mounting with press-fit and solder termination options. Shrouding configuration (4-wall shrouded design) and latch holder fastening type are identical.

Q: Which part should I select for new product designs?

A: For new designs, 5-103669-7 is the preferred selection due to RoHS Compliant status and higher inventory availability. This part aligns with current regulatory requirements and modern component specifications while maintaining full compatibility with the AMPMODU MTE series.
