Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HARTING 09185265921 is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Row Configuration: 26 positions arranged in 2 rows
• Pitch Specification: 0.100" (2.54mm) mating pitch with 0.100" row spacing
• Mounting & Orientation: Through-hole, right-angle mounting
• Shrouding Design: Shrouded with 4-wall construction
• Termination Method: Solder termination
• Fastening Mechanism: Push-pull fastening
• Contact Surface Finish: Gold-plated mating contacts
• Compliance & Environmental: ROHS3 compliance, UL94 V-0 flammability rating, MSL 1

The 3M N3429-5002RB meets all critical substitution criteria. Both parts share identical connector topology, position count, pitch, mounting method, shrouding configuration, and termination approach. Both are ROHS3 compliant with UL94 V-0 ratings and MSL 1 classification.

Parameter Comparison

Engineering Selection Recommendations

The 3M N3429-5002RB is a qualified substitute for the HARTING 09185265921 based on matching connector topology, position configuration, pitch specification, mounting method, and compliance certifications. Both parts are ROHS3 compliant and carry UL94 V-0 flammability ratings with MSL 1 classification.

Noted variations exist in contact post length (0.177" versus 0.112"), insulation height (0.335" versus 0.340"), insulation material composition (PBT versus PCT/Polyester), operating temperature upper limit (125°C versus 105°C), and insulation color (gray versus black). These variations do not affect functional substitution for standard board-to-cable/wire interconnection applications where the mating interface, position count, pitch, and mounting orientation are the primary design constraints.

Selection between these parts should be based on specific application requirements regarding maximum operating temperature, PCB layout constraints related to post length and insulation height, and any design specifications that mandate particular insulation material properties or color coding.

Frequently Asked Questions (FAQ)

Q: What makes the 3M N3429-5002RB a valid substitute for the HARTING 09185265921?

A: Both connectors share identical specifications for the critical substitution parameters: 26-position, 2-row header configuration with 0.100" (2.54mm) pitch, through-hole right-angle mounting, shrouded 4-wall design, solder termination, push-pull fastening, and gold-plated mating contacts. Both are ROHS3 compliant with UL94 V-0 ratings.

Q: Are there any differences I should be aware of before substituting?

A: Yes. The 3M part has a shorter contact post length (0.112" versus 0.177"), slightly taller insulation height (0.340" versus 0.335"), different insulation material (PCT/Polyester versus PBT), lower maximum operating temperature (105°C versus 125°C), and black insulation color instead of gray. Verify these variations do not conflict with your PCB layout, thermal requirements, or design specifications.

Q: Can I use the 3M N3429-5002RB in applications requiring operation above 105°C?

A: No. The 3M part is rated to -55°C ~ 105°C maximum. If your application requires sustained operation above 105°C, the HARTING 09185265921 with its -55°C ~ 125°C rating is the appropriate choice.

Q: Do the different insulation materials affect compatibility?

A: The insulation material difference (PBT versus PCT/Polyester) does not affect mating interface compatibility. Both materials are glass-filled, UL94 V-0 rated, and suitable for standard connector applications. Material selection should be based on specific environmental exposure, chemical resistance, or mechanical property requirements in your application.

Q: How do the contact post length differences impact PCB design?

A: The 3M part has a shorter post length (0.112" versus 0.177"). This may affect solder joint formation and PCB pad design. Verify that your PCB layout and solder process parameters accommodate the shorter post length before substitution.

Q: Are both parts available in equivalent quantities?

A: Inventory levels differ. The HARTING 09185265921 has 824 pieces in stock, while the 3M N3429-5002RB has 2290 pieces available. Supply chain considerations may favor one part over the other depending on project timelines and volume requirements.
