Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector headers is determined by strict alignment of electrical and mechanical parameters. The 3M N3433-5002RB qualifies as an equivalent substitute based on the following critical parameters:

Matching Parameters:

• Connector type: Header
• Contact type: Male pin
• Number of positions: 50
• Number of rows: 2
• Pitch - mating: 0.100" (2.54mm)
• Row spacing - mating: 0.100" (2.54mm)
• Mounting type: Through hole, right angle
• Shrouding: Shrouded - 4 wall
• Termination: Solder
• Fastening type: Push-pull
• Contact finish - mating: Gold
• Contact finish - post: Tin
• Contact material: Copper alloy
• Material flammability rating: UL94 V-0
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance: Confirmed

These parameters define the functional and physical compatibility required for direct substitution in board-to-cable/wire interconnect applications.

Parameter Comparison

Engineering Selection Recommendations

Both the HARTING 09185507921 and 3M N3433-5002RB are active products with confirmed RoHS compliance and UL94 V-0 flammability ratings. Selection between these parts should account for the following documented differences:

Operating Temperature: The HARTING part supports -55°C to 125°C, while the 3M substitute operates to -55°C to 105°C. Applications requiring operation above 105°C require the HARTING part.

Insulation Material: The HARTING part uses PBT (polybutylene terephthalate) while the 3M part uses PCT (polycyclohexylenedimethylene terephthalate) with polyester. Both are glass-filled and UL94 V-0 rated. Material selection depends on specific environmental and chemical exposure requirements.

Contact Post Length: The HARTING part provides 0.177" (4.50mm) post length versus 0.112" (2.84mm) for the 3M part. PCB design and solder joint geometry must accommodate this difference.

Current Rating: The 3M part specifies 1.75A per contact. The HARTING part does not provide a current rating specification. Applications with defined current requirements should reference the 3M specification or contact HARTING for clarification.

Both parts maintain identical pitch, position count, shrouding configuration, and contact finish specifications required for mechanical and electrical compatibility in board-to-cable/wire interconnect applications.

Frequently Asked Questions (FAQ)

Q: Can the 3M N3433-5002RB directly replace the HARTING 09185507921 in all applications?

A: Direct replacement is possible for applications operating within -55°C to 105°C. Applications requiring operation above 105°C require the HARTING part due to its extended temperature rating to 125°C. PCB design must accommodate the shorter contact post length of the 3M part (0.112" versus 0.177").

Q: What are the key compatibility criteria for these rectangular connector headers?

A: Compatibility is determined by matching pitch (0.100"/2.54mm), position count (50), row configuration (2 rows), mounting type (through hole, right angle), shrouding (4 wall), contact type (male pin), and termination method (solder). Both parts meet these criteria.

Q: How do the insulation materials differ between these parts?

A: The HARTING part uses PBT (polybutylene terephthalate) while the 3M part uses PCT (polycyclohexylenedimethylene terephthalate) with polyester. Both are glass-filled and UL94 V-0 rated. Material selection should be based on specific chemical exposure, humidity, and thermal cycling requirements of the application.

Q: What is the significance of the contact post length difference?

A: The HARTING part provides 0.177" (4.50mm) post length while the 3M part provides 0.112" (2.84mm). This difference affects solder joint geometry and PCB pad design. Designs must be verified to accommodate the shorter post length of the 3M substitute.

Q: Are both parts RoHS compliant?

A: Yes. The HARTING part is ROHS3 compliant and the 3M part is RoHS compliant. Both meet RoHS requirements for restricted substance elimination.

Q: What current rating should be used for design calculations?

A: The 3M part specifies 1.75A per contact. The HARTING part does not provide a current rating in the available specifications. For applications with defined current requirements, use the 3M specification or contact HARTING directly for the HARTING part rating.
