Part Overview

The 3M 3429-5002UG is a through-hole, right-angle rectangular connector header with 26 positions at 2.54mm pitch, designed for board-to-board or cable interconnection applications. This part carries an obsolete product status, making identification of functionally equivalent alternatives essential for ongoing design support and procurement planning. Substitute parts must maintain electrical and mechanical compatibility across the specified parameter set while accommodating modern availability and compliance requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the 3429-5002UG is determined by strict equivalence across the following critical parameters:

Connector type (Header), contact type (Male Pin), and position count (26 positions in 2-row configuration)
Pitch specification (0.100" / 2.54mm mating pitch with 0.100" row spacing)
Mounting method (Through Hole, Right Angle) and shrouding style (Shrouded - 4 Wall)
Termination method (Solder) and current rating (1.75A)
Operating temperature range (-55°C ~ 105°C)
Material flammability compliance (UL94 V-0)

The following parts meet these substitution criteria: 3429-5002 (3M, Bulk packaging), D3429-5002-AR (3M, Tray packaging, Active status), N3429-5002RB (3M, Bulk packaging, Active status), 65823-073 (Amphenol ICC, Bulk packaging), and 65823-169 (Amphenol ICC, Bulk packaging).

Engineering Selection Recommendations

For applications requiring active product status and modern compliance, D3429-5002-AR (3M, ROHS3 Compliant, Active) and N3429-5002RB (3M, ROHS3 Compliant, Active) are the primary 3M alternatives. Both maintain full electrical and mechanical compatibility with the obsolete 3429-5002UG while offering current manufacturing support and regulatory compliance.

The 3429-5002 (3M, Bulk) provides direct functional equivalence but retains obsolete status and RoHS non-compliance, suitable only for legacy system maintenance where compliance is not required.

Amphenol ICC alternatives 65823-073 and 65823-169 (Quickie™ series) deliver functional substitution with active product status but carry RoHS non-compliance. These parts are suitable for applications where cross-manufacturer sourcing is acceptable and compliance requirements align with the original design.

Frequently Asked Questions (FAQ)

Q: Can 3429-5002 be used as a direct replacement for 3429-5002UG?

A: Yes. Both parts share identical electrical and mechanical specifications including 26-position, 2.54mm pitch, through-hole right-angle configuration, 1.75A current rating, and -55°C to 105°C operating range. The primary difference is product status; 3429-5002 is also obsolete.

Q: What is the difference between D3429-5002-AR and N3429-5002RB?

A: Both are active 3M alternatives with ROHS3 compliance. D3429-5002-AR uses Brass contact material with Tin post finish (39.4µin thickness), while N3429-5002RB uses Copper Alloy with Tin post finish (200.0µin thickness). Both maintain the required 26-position, 2.54mm pitch configuration and 1.75A current rating.

Q: Are Amphenol ICC 65823-073 and 65823-169 fully compatible?

A: Both Amphenol ICC parts meet the core substitution criteria: 26-position, 2.54mm pitch, through-hole right-angle headers with shrouded 4-wall configuration and solder termination. Operating temperature and current rating specifications are not provided for these parts. The primary distinction is fastening type; 65823-073 uses Latch Lock/Eject Hooks while 65823-169 uses Latch Lock/Eject Hooks, Short variant.

Q: What packaging options are available?

A: 3429-5002 and N3429-5002RB are supplied in Bulk packaging. D3429-5002-AR is supplied in Tray packaging. Amphenol ICC alternatives 65823-073 and 65823-169 are supplied in Bulk packaging. Packaging selection should align with assembly process requirements and inventory management practices.

Q: Which substitute offers the best compliance profile?

A: D3429-5002-AR and N3429-5002RB both carry ROHS3 Compliant status with active product status, providing the strongest regulatory alignment for new designs and ongoing production support.
