HARTING 09185506923 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The HARTING 09185506923 is an active rectangular connector header designed for through-hole, right-angle board-to-cable/wire applications. This shrouded 50-position header with 2.54mm pitch serves as an interconnect solution in electronic assemblies requiring reliable push-pull fastening and keyed mating. Substitute parts are identified to provide alternative sourcing options while maintaining functional and mechanical compatibility within the specified parameter constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector headers is determined by strict alignment of the following parameters:

• Connector geometry: 50 positions, 2 rows, 0.100" (2.54mm) pitch and row spacing
• Mounting configuration: Through-hole, right-angle orientation
• Shrouding design: 4-wall shrouded structure with keying slot
• Contact system: Male pin contacts with gold-plated mating surfaces and tin-plated posts
• Fastening mechanism: Push-pull fastening type
• Insulation material class: Glass-filled thermoplastic (PBT or equivalent)
• Compliance certifications: UL94 V-0 flammability rating, RoHS compliance, REACH unaffected status

The 3M N3433-5002RB meets these core substitution criteria. Variations in contact post length (0.114" vs. 0.112"), insulation height (0.335" vs. 0.340"), insulation material composition (PBT vs. PCT/Polyester blend), and operating temperature maximum (-55°C to 125°C vs. -55°C to 105°C) are within acceptable tolerance ranges for this connector category and do not preclude functional substitution in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both the HARTING 09185506923 and 3M N3433-5002RB are active products with equivalent functional specifications for 50-position, 2.54mm-pitch rectangular connector header applications. Both maintain UL94 V-0 flammability certification, RoHS compliance, and unlimited moisture sensitivity classification.

The 3M N3433-5002RB operates within a reduced maximum temperature range (-55°C to 105°C versus -55°C to 125°C). Selection between these parts should be based on application temperature requirements and design constraints. The minor dimensional variations in contact post length and insulation height fall within standard manufacturing tolerances for this connector category and do not affect mechanical or electrical compatibility in standard through-hole PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 3M N3433-5002RB directly replace the HARTING 09185506923 in all applications?

A: Direct substitution is valid for applications operating within the 3M part's temperature range (-55°C to 105°C). Applications requiring operation above 105°C must use the HARTING part. Both parts share identical pitch, position count, shrouding design, and fastening mechanism.

Q: What is the significance of the insulation material difference (PBT vs. PCT/Polyester)?

A: Both materials are glass-filled thermoplastics with UL94 V-0 flammability ratings. The material composition difference does not affect electrical performance or mechanical compatibility in standard applications. Material selection may influence thermal stability and chemical resistance in specialized environments.

Q: Are the contact post length variations (0.114" vs. 0.112") critical for PCB design?

A: The 0.002" (0.06mm) difference is within standard PCB through-hole tolerance specifications and does not require design modification. Both parts are suitable for standard 0.125" (3.18mm) minimum hole depth requirements.

Q: Do both parts support the same mating connector types?

A: Yes. Both headers feature identical 50-position, 2.54mm-pitch, 4-wall shrouded geometry with keying slots and push-pull fastening. They mate with standard 2.54mm-pitch receptacle connectors designed for this pitch and shrouding configuration.

Q: What compliance certifications apply to both parts?

A: Both parts are RoHS compliant, REACH unaffected, UL94 V-0 rated, and carry MSL 1 (unlimited) moisture sensitivity classification. The HARTING part is ROHS3 compliant; the 3M part is RoHS compliant. Both meet the same functional compliance requirements for standard industrial and commercial applications.
