Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-104354-8 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 50
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole, Right Angle
• Shrouding: Unshrouded
• Contact Shape: Square
• Insulation Material: Thermoplastic-based
• Material Flammability Rating: UL94 V-0

Allowable Parameter Variations: Substitute parts may differ in the following parameters while maintaining functional equivalence:

• Product Status (Active substitutes acceptable for obsolete parts)
• Termination method (Press-Fit, Solder, or combined)
• Contact Finish composition (Gold on mating surface required; post finish may vary)
• Contact Finish Thickness (minor variations acceptable)
• Operating Temperature Range (substitute range must encompass or exceed original)
• Current Rating (substitute must meet or exceed original rating)
• Voltage Rating (substitute must meet or exceed original rating)
• RoHS Compliance Status (newer substitutes may be RoHS compliant)

The 3M 929667-04-25-I meets all mandatory matching parameters and qualifies as a functional substitute.

Engineering Selection Recommendations

Primary Substitute: 3M 929667-04-25-I

The 3M 929667-04-25-I qualifies as a functional substitute for the obsolete TE Connectivity 1-104354-8 based on the following engineering criteria:

Mechanical Compatibility: All critical dimensional parameters align: 50-position, 2-row configuration with 0.100" (2.54mm) pitch spacing and row spacing. Both connectors feature through-hole, right-angle mounting with square male pin contacts and unshrouded design. Physical board interface compatibility is established.

Electrical Compatibility: Both connectors feature gold-plated mating contacts and copper alloy contact material. The 3M substitute provides a current rating of 2.5A compared to the original 3A rating. For applications operating at or below 2.5A, direct substitution is appropriate. Applications requiring the full 3A capacity of the original part require evaluation of circuit requirements.

Compliance and Product Status: The 3M 929667-04-25-I is an active product with current manufacturing support, addressing the obsolescence status of the TE Connectivity part. The 3M substitute achieves RoHS compliance, meeting modern regulatory requirements. Both parts maintain UL94 V-0 flammability certification.

Termination Considerations: The TE Connectivity original supports both press-fit and solder termination. The 3M substitute supports solder termination only. Applications utilizing press-fit termination require alternative solutions or process modification to solder-based assembly.

Temperature Range Consideration: The original part operates from -65°C to 105°C. The 3M substitute operates from -40°C to 105°C. Applications requiring operation below -40°C cannot use this substitute without thermal performance verification.

Contact Finish Post Difference: The original part features tin-lead post finish; the 3M substitute features gold post finish. This difference does not affect functional compatibility for standard solder termination applications.

Frequently Asked Questions (FAQ)

Q: Can the 3M 929667-04-25-I directly replace the TE Connectivity 1-104354-8 in all applications?

A: Direct replacement is appropriate for applications meeting these conditions: operating current does not exceed 2.5A, operating temperature range does not go below -40°C, and solder termination is acceptable. Applications with different requirements require alternative solutions.

Q: What is the significance of the different current ratings (3A vs. 2.5A)?

A: The current rating represents the maximum continuous current each contact can safely carry. The 3M substitute is rated for 2.5A per contact. Applications drawing 2.5A or less per contact operate within specification. Applications requiring 2.5A to 3A per contact exceed the 3M substitute specification and require alternative components.

Q: Why does the 3M part have a narrower operating temperature range?

A: The 3M 929667-04-25-I operates from -40°C to 105°C, while the original operates from -65°C to 105°C. The 3M substitute does not support operation below -40°C. Applications requiring low-temperature operation below -40°C must use alternative components or verify thermal performance through testing.

Q: What is the difference between press-fit and solder termination?

A: Press-fit termination uses mechanical pressure to insert contacts into plated through-holes without solder. Solder termination requires melting solder to create electrical and mechanical connection. The original TE Connectivity part supports both methods; the 3M substitute supports solder only. Applications using press-fit assembly require process modification or alternative components.

Q: Does the difference in contact finish (tin-lead vs. gold) affect compatibility?

A: Both finishes are compatible with standard solder termination processes. The tin-lead finish on the original part and gold finish on the 3M substitute both provide adequate solderability. This difference does not affect functional compatibility for solder-based assembly.

Q: What does RoHS compliance mean for this substitution?

A: RoHS (Restriction of Hazardous Substances) compliance restricts use of lead, cadmium, and other hazardous materials. The original TE Connectivity part is RoHS non-compliant; the 3M substitute is RoHS compliant. For applications subject to RoHS regulations or customer requirements, the 3M substitute meets modern compliance standards.

Q: Are there dimensional differences that could affect PCB layout?

A: Minor dimensional variations exist: contact length mating (0.230" vs. 0.235"), contact length post (0.120" vs. 0.145"), and insulation height (0.238" vs. 0.215"). These variations are within typical manufacturing tolerances for connector interfaces. Standard PCB layouts designed for 0.100" pitch headers accommodate both parts.

Q: What inventory status should influence my selection?

A: The TE Connectivity 1-104354-8 is obsolete with 804 pieces in stock. The 3M 929667-04-25-I is an active product with 894 pieces in stock. For long-term supply security and ongoing production, the active 3M part provides better availability and manufacturing continuity.
