Key Parameters

Substitute Part Grouping Explanation

The 3M N3429-5002RB qualifies as an equivalent substitute for the HARTING 09185267921 based on the following critical parameters:

Matching Specifications:

• Connector type: Header with male pin contacts
• Position count: 26 positions in 2-row configuration
• Pitch: 0.100" (2.54mm) mating pitch with 0.100" row spacing
• Mounting: Through-hole, right-angle orientation
• Shrouding: 4-wall shrouded design
• Termination: Solder attachment
• Fastening: Push-pull mechanism
• Contact finish: Gold mating surface with tin post finish
• Contact material: Copper alloy
• Flammability: UL94 V-0 rated
• Compliance: ROHS3 compliant, REACH unaffected

Substitution Basis: Electrical and mechanical interchangeability is established through identical mating pitch, position count, row configuration, contact geometry, and mounting methodology. Both connectors support equivalent board-to-cable/wire applications with identical shrouding and fastening characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the HARTING 09185267921 and 3M N3429-5002RB are active production components with ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on application-specific operating temperature requirements and PCB design constraints.

The HARTING part supports an extended operating temperature range of -55°C to 125°C, making it suitable for applications requiring higher temperature performance. The 3M part operates within -55°C to 105°C, appropriate for standard industrial and commercial temperature environments.

Post contact length differs between the two designs (0.177" versus 0.112"), which may affect PCB layout and solder joint geometry. Insulation material composition varies, with HARTING using PBT and 3M using PCT polyester, both glass-filled formulations rated for equivalent flammability performance.

Current rating is specified for the 3M part (1.75A) but not provided for the HARTING part. Voltage rating information is not available for either connector. Both connectors maintain identical mating pitch, position count, shrouding configuration, and fastening mechanism, ensuring mechanical and electrical interchangeability within their respective temperature operating ranges.

Frequently Asked Questions (FAQ)

Q: Can the 3M N3429-5002RB directly replace the HARTING 09185267921 in all applications?

A: Direct replacement is possible for applications operating within the 3M part's temperature range of -55°C to 105°C. Applications requiring operation above 105°C must use the HARTING part, which supports temperatures to 125°C. Both connectors share identical mating pitch, position count, shrouding, and fastening characteristics.

Q: What is the significance of the different post contact lengths?

A: The HARTING part features 0.177" (4.50mm) post length while the 3M part has 0.112" (2.84mm) post length. This difference affects solder joint formation and PCB hole depth requirements. PCB design must accommodate the specific post length of the selected connector to ensure proper solder joint quality and mechanical stability.

Q: Are both connectors suitable for high-reliability applications?

A: Both connectors meet ROHS3 compliance and UL94 V-0 flammability requirements. Moisture sensitivity level is identical at MSL 1 (Unlimited) for both parts. Selection should be based on specific application temperature requirements and compliance certifications mandated by the end-use industry.

Q: What is the difference between the insulation materials used?

A: HARTING uses polybutylene terephthalate (PBT) glass-filled insulation, while 3M uses polycyclohexylenedimethylene terephthalate (PCT) polyester glass-filled insulation. Both materials achieve UL94 V-0 flammability rating. Material selection may affect chemical resistance and long-term environmental performance in specific application environments.

Q: How do the two connectors differ in terms of availability?

A: HARTING 09185267921 has 676 units in stock. 3M N3429-5002RB has 2290 units in stock. Availability should be considered when planning procurement for production schedules or inventory management.
