3M 3429-600T02TC Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 3429-600T02TC is a through-hole rectangular connector header with 26 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This component features shrouded 4-wall construction with gold-plated mating contacts and tin-lead plated posts, designed for board-to-board or cable interconnection applications. The part is classified as obsolete, making equivalent substitute parts necessary for ongoing procurement and system maintenance.

Substitute Part Grouping Explanation

Substitution eligibility for the 3429-600T02TC is determined by the following critical parameters:

Connector type (Header)
Contact type (Male Pin)
Number of positions (26)
Number of rows (2)
Pitch - mating (0.100" / 2.54mm)
Row spacing - mating (0.100" / 2.54mm)
Shrouding configuration (Shrouded - 4 Wall)
Mounting type (Through Hole)
Fastening type (Push-Pull)
Operating temperature range (-55°C ~ 105°C)
Material flammability rating (UL94 V-0)

All identified substitute parts maintain these core electrical and mechanical parameters. Variations in contact finish thickness, insulation material composition, contact post length, and RoHS compliance status do not affect functional interchangeability within the specified parameter constraints.

Engineering Selection Recommendations

D3429-6002-AR is the primary recommended substitute. This part maintains all critical electrical and mechanical parameters while offering active product status and ROHS3 compliance. The increased current rating of 1.75A provides additional design margin compared to the original 1A specification. Tray packaging supports automated assembly processes.

N3429-6002RB serves as an alternative substitute with active product status and RoHS compliance. This part matches the original 3429-600T02TC in RoHS compliance classification and provides the same 1.75A current rating as D3429-6002-AR. Bulk packaging is suitable for manual assembly or lower-volume applications.

3429-6002 is functionally equivalent but remains classified as obsolete with RoHS non-compliance status. This part should be considered only when active alternatives are unavailable and RoHS compliance is not a system requirement.

Frequently Asked Questions (FAQ)

Q: Can D3429-6002-AR be used as a direct replacement for 3429-600T02TC?

A: Yes. Both parts maintain identical connector type, contact configuration, position count, pitch, row spacing, shrouding, mounting type, and fastening mechanism. The higher current rating of D3429-6002-AR (1.75A versus 1A) is compatible with applications designed for the original 1A specification.

Q: What is the difference between the substitute parts?

A: The three substitutes differ in product status, RoHS compliance, and packaging format. D3429-6002-AR and N3429-6002RB are active products with current RoHS compliance. The 3429-6002 remains obsolete and RoHS non-compliant. D3429-6002-AR uses tray packaging while N3429-6002RB uses bulk packaging.

Q: Does the contact finish thickness variation affect compatibility?

A: No. Contact finish thickness variations (ranging from 10.0µin to 200.0µin on mating surfaces) do not affect electrical or mechanical interchangeability within the specified operating parameters.

Q: Are there packaging considerations for substitution?

A: Yes. D3429-6002-AR is supplied in tray packaging suitable for automated pick-and-place assembly. N3429-6002RB and 3429-6002 are supplied in bulk packaging. Packaging selection should align with assembly process requirements.

Q: Is the insulation material composition change significant?

A: No. All substitute parts maintain UL94 V-0 flammability rating and operate within the same temperature range (-55°C ~ 105°C). Insulation material variations between PCT and PBT formulations do not affect functional performance within these constraints.
