HARTING 09185505921 Equivalent & Substitute Parts

Part Overview

The HARTING 09185505921 is a rectangular connector header designed for through-hole, right-angle board-to-cable applications. This shrouded 50-position connector operates across -55°C to 125°C and features gold-plated mating contacts with tin-plated posts. The part is currently active in production with 1161 units in stock. Equivalent parts are identified to support procurement flexibility, design revisions, or supply chain continuity when the primary part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HARTING 09185505921 is determined by strict alignment of the following electrical and mechanical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Row Configuration: 50 positions arranged in 2 rows
• Pitch Specification: 0.100" (2.54mm) mating pitch and 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 Materials & Finishes: Gold-plated mating contacts, tin-plated posts, copper alloy base
• Insulation Material: Glass-filled thermoplastic (PBT or equivalent)
• Flammability Rating: UL94 V-0
• Environmental Compliance: RoHS3 and REACH compliance

The 3M N3433-5002RB meets all critical substitution criteria. Minor variations in insulation material composition (PCT/Polyester vs. PBT), insulation color, and post contact length do not affect functional interchangeability in standard board-to-cable applications.

Parameter Comparison

Engineering Selection Recommendations

Both the HARTING 09185505921 and 3M N3433-5002RB are active production parts with full RoHS and REACH compliance. Selection between these parts is based on application-specific thermal and electrical requirements:

HARTING 09185505921 is suitable for applications requiring the extended operating temperature range of -55°C to 125°C. This part should be selected when thermal performance at elevated temperatures is a design requirement.

3M N3433-5002RB is suitable for applications operating within -55°C to 105°C and where a specified current rating of 1.75A per contact is required. This part provides documented electrical performance specifications.

Both parts feature identical mating pitch, position count, shrouding design, and contact finish specifications. The difference in post contact length (0.177" vs. 0.112") reflects design variations between manufacturers but does not affect functional interchangeability in standard through-hole solder applications. Both parts carry UL94 V-0 flammability certification and unlimited moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can the 3M N3433-5002RB be used as a direct replacement for the HARTING 09185505921?

A: Yes, for applications operating within the 3M part's temperature range of -55°C to 105°C. Both parts share identical mating pitch (0.100"), position count (50), row configuration (2 rows), shrouding design (4-wall), and contact finishes. The primary difference is the maximum operating temperature; the HARTING part extends to 125°C.

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

A: The HARTING part has a post contact length of 0.177" (4.50mm) while the 3M part measures 0.112" (2.84mm). This variation reflects different manufacturing designs but does not affect solder joint quality or electrical performance in standard through-hole PCB applications where post length is not a critical constraint.

Q: Are both parts RoHS compliant?

A: Yes. The HARTING 09185505921 is ROHS3 compliant, and the 3M N3433-5002RB is RoHS compliant. Both meet current environmental regulations for electronic component manufacturing.

Q: What is the difference in insulation material between these parts?

A: The HARTING part uses polybutylene terephthalate (PBT) glass-filled insulation, while the 3M part uses polycyclohexylenedimethylene terephthalate (PCT) and polyester glass-filled insulation. Both materials are glass-filled thermoplastics with UL94 V-0 flammability ratings and provide equivalent electrical insulation properties for this connector class.

Q: Does the 3M part specify a current rating while the HARTING part does not?

A: The 3M N3433-5002RB provides a documented current rating of 1.75A per contact. The HARTING 09185505921 does not specify a current rating in the provided data. For applications requiring explicit current specifications, the 3M part provides this documentation.

Q: Are both parts available in bulk packaging?

A: Yes. Both the HARTING 09185505921 (1161 units in stock) and 3M N3433-5002RB (1041 units in stock) are supplied in bulk packaging.
