3M 3408-5402 Equivalent & Substitute Parts

Part Overview

The 3M 3408-5402 is a rectangular connector header, right-angle configuration, with 16 positions at 0.100" (2.54mm) pitch. This through-hole component features shrouded 4-wall design with solder termination and ejector fastening. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Active alternatives from TE Connectivity AMP Connectors series provide functional equivalence while maintaining current product status and improved compliance profiles.

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 3408-5402 is determined by the following mandatory parameters:

Connector type: Header
Contact type: Male Pin
Number of positions: 16
Number of rows: 2
Pitch - mating: 0.100" (2.54mm)
Row spacing - mating: 0.100" (2.54mm)
Mounting type: Through Hole, Right Angle
Shrouding: Shrouded - 4 Wall
Termination: Solder
Contact shape: Square
Material flammability rating: UL94 V-0
Moisture sensitivity level: 1 (Unlimited)

All four substitute parts (102322-3, 5102322-3, 2-5499141-3, 499141-3) meet these core electrical and mechanical requirements. Variations in contact length specifications, contact finish materials, and fastening mechanism details (ejector versus latch lock) do not preclude functional substitution within the defined parameter set.

Engineering Selection Recommendations

All four substitute parts are active products from TE Connectivity AMP Connectors series and provide functional equivalence to the obsolete 3M 3408-5402 based on core electrical and mechanical parameters.

For applications requiring RoHS compliance, TE 5102322-3 (RoHS Compliant) or TE 2-5499141-3 (ROHS3 Compliant) are appropriate selections. TE 5102322-3 offers the highest inventory availability (1766 pcs) and RoHS compliance status.

For applications without RoHS compliance requirements, TE 102322-3 and TE 499141-3 remain valid alternatives. TE 102322-3 is available in tray packaging (769 pcs), while TE 499141-3 is available in bulk packaging (631 pcs).

Current rating differences (1.75A for the original part versus 1A per contact for substitutes) and contact material variations (copper alloy versus brass) should be evaluated against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity AMP Connectors parts directly replace the 3M 3408-5402?

A: Yes. All four substitute parts meet the core substitution parameters: 16-position, 2-row header configuration at 0.100" (2.54mm) pitch, through-hole right-angle mounting, shrouded 4-wall design, solder termination, and square contact shape. Functional compatibility is established through these parameters.

Q: What is the difference between TE 102322-3 and TE 5102322-3?

A: Both parts are mechanically and electrically equivalent. TE 5102322-3 is RoHS Compliant, while TE 102322-3 is RoHS non-compliant. TE 5102322-3 has higher inventory availability (1766 pcs versus 769 pcs) and offers superior compliance status for regulated applications.

Q: How do the contact post lengths differ among substitutes?

A: TE 102322-3 and TE 5102322-3 feature 0.155" (3.94mm) contact post length, while TE 2-5499141-3 and TE 499141-3 feature 0.110" (2.79mm) contact post length. Both configurations are valid substitutes within the defined parameter set. PCB design and mating connector specifications should determine the appropriate selection.

Q: What packaging options are available?

A: TE 102322-3 and TE 5102322-3 are supplied in tray packaging. TE 2-5499141-3 is supplied in tray packaging. TE 499141-3 is supplied in bulk packaging. Packaging selection depends on procurement and assembly requirements.

Q: Are there compliance differences between the substitute parts?

A: Yes. TE 2-5499141-3 is ROHS3 Compliant and REACH Unaffected. TE 5102322-3 is RoHS Compliant with Vendor Undefined REACH status. TE 102322-3 and TE 499141-3 are RoHS non-compliant. Applications subject to RoHS or REACH regulations should specify TE 2-5499141-3 or TE 5102322-3.

Q: What is the operating temperature range for substitute parts?

A: All substitute parts operate from -65°C to 105°C, which exceeds the original part specification of -55°C to 105°C. This represents an improvement in low-temperature performance.
