Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 103669-4 are identified based on strict equivalence of core electrical and mechanical parameters. The substitution logic is based on the following criteria:

Critical Parameters for Substitution:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 5
• Number of Rows: 1
• Pitch - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Press-Fit, Solder
• Shrouding: Shrouded - 4 Wall
• Current Rating: 3A
• Operating Temperature: -65°C ~ 105°C
• Material Flammability Rating: UL94 V-0
• Contact Material: Brass
• Insulation Material: Thermoplastic
• Overall Contact Length: 0.545" (13.84mm)
• Insulation Height: 0.535" (13.60mm)
• Contact Shape: Square
• Features: Keying Slot
• Fastening Type: Latch Holder

All identified substitute parts maintain these parameters. Variations in contact finish composition (Tin-Lead versus Tin) and RoHS compliance status do not affect functional interchangeability in circuit applications. Both substitute parts belong to the same AMPMODU MTE series and share the base product number 103669.

Parameter Comparison

Engineering Selection Recommendations

All three parts—103669-4, 2-103669-7, and 5-103669-4—are Active product status connectors from the TE Connectivity AMPMODU MTE series and are functionally equivalent for circuit applications requiring 5-position, 0.100" pitch through-hole headers with 3A current capacity and -65°C to 105°C operating range.

103669-4 (Main Part): This part features Tin-Lead contact finish and carries "Not applicable" RoHS status. It is suitable for applications where Tin-Lead plating is specified or where RoHS compliance is not a requirement.

2-103669-7 (Substitute): This part features Tin contact finish and is ROHS3 Compliant. It is suitable for applications requiring RoHS3 compliance with Tin plating. Inventory availability is 628 pieces.

5-103669-4 (Substitute): This part features Tin contact finish and is RoHS Compliant. It is suitable for applications requiring RoHS compliance with Tin plating. This part has the highest inventory availability at 26,961 pieces, making it the most readily available option.

Selection between these parts depends on specific regulatory requirements (RoHS compliance level) and contact finish specifications for the application. All parts maintain identical mechanical fit, electrical performance, and thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Can 2-103669-7 and 5-103669-4 be used interchangeably with 103669-4?

A: Yes. All three parts maintain identical electrical and mechanical parameters including connector type, position count, pitch, current rating, operating temperature range, and physical dimensions. The primary differences are contact finish composition and RoHS compliance status, which do not affect functional interchangeability in circuit applications.

Q: What is the difference between Tin-Lead and Tin contact finishes?

A: The main part 103669-4 uses Tin-Lead contact finish, while substitutes 2-103669-7 and 5-103669-4 use Tin contact finish. Both finishes provide equivalent electrical conductivity and contact reliability. The choice depends on application-specific requirements and regulatory compliance needs.

Q: Are these parts RoHS compliant?

A: The main part 103669-4 carries "Not applicable" RoHS status. Substitute 2-103669-7 is ROHS3 Compliant. Substitute 5-103669-4 is RoHS Compliant. Applications requiring RoHS compliance should specify either 2-103669-7 or 5-103669-4.

Q: Do all three parts have the same physical dimensions?

A: Yes. All three parts share identical overall contact length (0.545" / 13.84mm), insulation height (0.535" / 13.60mm), and all other mechanical specifications. They are mechanically interchangeable in PCB layouts and cable assemblies.

Q: What is the current rating for these connectors?

A: All three parts are rated for 3A continuous current. This rating applies to each individual contact position.

Q: What is the operating temperature range?

A: All three parts operate across the temperature range of -65°C to 105°C, suitable for automotive, medical, and telecommunications applications.

Q: Are these connectors keyed?

A: Yes. All three parts feature a keying slot, which prevents incorrect mating orientation and ensures proper connector alignment.

Q: What mounting method do these connectors use?

A: All three parts use through-hole mounting with press-fit and solder termination options, suitable for standard PCB assembly processes.

Q: Which substitute part has the best inventory availability?

A: Part 5-103669-4 has the highest inventory availability with 26,961 pieces in stock, compared to 628 pieces for 2-103669-7 and 987 pieces for the main part 103669-4.

Q: Can these connectors be used in automotive applications?

A: Yes. All three parts are specified for automotive applications and meet the required flammability rating of UL94 V-0.
