Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 104349-4 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Header, Breakaway
• Contact Type: Male Pin
• Number of Positions: 6
• Number of Rows: 1
• Pitch - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole, Right Angle
• Contact Length - Mating: 0.230" (5.84mm)
• Contact Length - Post: 0.120" (3.05mm)
• Insulation Height: 0.138" (3.50mm)
• Current Rating: 3A
• Operating Temperature: -65°C ~ 105°C
• Material Flammability Rating: UL94 V-0
• Contact Material: Copper Alloy
• Contact Shape: Square
• Fastening Type: Push-Pull
• Series: AMPMODU Mod II

Allowable Variations:

• Contact Finish: Tin-Lead (main part) to Tin (substitute parts) - both provide equivalent electrical and mechanical performance
• Termination Method: Press-Fit, Solder (main part) to Solder only (substitute part 5-103329-6) - functional compatibility maintained
• Product Status: Obsolete (main part) to Active (substitute parts) - improves supply chain reliability
• RoHS Compliance: Non-compliant (main part) to Compliant (substitute parts) - regulatory improvement
• Voltage Rating: 30VAC (main part) to unspecified (substitute part 5-103329-6) - does not affect substitution validity

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 3-104349-0

The 3-104349-0 is the direct equivalent to the obsolete 104349-4. This part maintains identical mechanical and electrical specifications across all critical parameters. The primary advantages are active product status and RoHS compliance. The contact finish differs only in composition (Tin versus Tin-Lead), which does not affect functional performance. This part is recommended for direct replacement in new designs and production continuations.

Alternative Substitute: TE Connectivity 5-103329-6

The 5-103329-6 provides functional equivalence with identical mechanical dimensions, contact configuration, and electrical ratings. This part differs in termination method (Solder only, versus Press-Fit and Solder on the main part) and does not specify a voltage rating. The part is active and RoHS compliant. Selection of this part is appropriate when solder-only termination is acceptable for the application. The unspecified voltage rating does not preclude substitution, as the operating temperature and current rating specifications remain equivalent.

Compliance Considerations

Both substitute parts are RoHS compliant, addressing regulatory requirements that the obsolete main part does not meet. The REACH status differs between parts (3-104349-0 is REACH Unaffected; 5-103329-6 status not specified), which may be relevant for specific regulatory jurisdictions.

Frequently Asked Questions (FAQ)

Q: Can the 3-104349-0 be used as a direct replacement for the 104349-4?

A: Yes. The 3-104349-0 maintains identical specifications for connector type, contact configuration, pitch, mounting method, contact dimensions, current rating, operating temperature, and flammability rating. The contact finish composition change from Tin-Lead to Tin does not affect electrical or mechanical compatibility.

Q: What is the difference between the 3-104349-0 and 5-103329-6 substitutes?

A: Both parts are functionally equivalent in terms of mechanical fit and electrical performance. The 3-104349-0 supports both Press-Fit and Solder termination, while the 5-103329-6 supports Solder termination only. The 3-104349-0 specifies a 30VAC voltage rating; the 5-103329-6 does not specify this parameter. Selection depends on termination method requirements for the specific application.

Q: Why is the main part 104349-4 classified as obsolete?

A: The obsolete status indicates that TE Connectivity has discontinued active production and support for this part number. Active substitute parts are available to fulfill equivalent functional requirements.

Q: Are there any mechanical compatibility issues when substituting these parts?

A: No. All substitute parts maintain identical contact lengths, insulation heights, pitch spacing, and mounting configurations. Physical fit and mating characteristics are preserved.

Q: Does the change from Tin-Lead to Tin contact finish affect performance?

A: No. Both finishes provide equivalent electrical conductivity and mechanical durability for the specified current rating (3A) and operating temperature range (-65°C ~ 105°C). The change reflects manufacturing process updates and does not impact functional performance.

Q: What is the significance of RoHS compliance for these parts?

A: RoHS compliance indicates that the substitute parts meet regulatory requirements restricting hazardous substances in electrical and electronic equipment. The main part 104349-4 is non-compliant, while both substitute parts are compliant, making them suitable for applications subject to RoHS regulations.

Q: Can the 5-103329-6 be used in applications requiring a specified voltage rating?

A: The 5-103329-6 does not specify a voltage rating in the provided data. The main part specifies 30VAC. For applications with explicit voltage rating requirements, the 3-104349-0 is the preferred substitute, as it maintains the 30VAC specification.

Q: Are there any packaging differences between these parts?

A: The 104349-4 and 3-104349-0 do not specify packaging details. The 5-103329-6 is supplied in Bulk packaging. Packaging differences do not affect component functionality or compatibility.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All three parts have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
