HARTING 09185107912 Equivalent & Substitute Parts

Part Overview

The HARTING 09185107912 is an active rectangular connector header designed for through-hole mounting applications. This shrouded 10-position connector with 2.54mm pitch serves board-to-cable/wire interconnection requirements. The part is manufactured with gold-plated mating contacts and tin-plated posts, utilizing polybutylene terephthalate (PBT) glass-filled insulation. With 644 units currently in stock and ROHS3 compliance, this connector is suitable for applications requiring reliable solder termination in temperature ranges from -55°C to 125°C. Equivalent substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when design flexibility is required.

Substitute Part Grouping Explanation

Substitution eligibility for the HARTING 09185107912 is determined by strict alignment with the following critical parameters:

Primary Substitution Criteria:

• Connector type: Header
• Contact type: Male pin
• Number of positions: 10
• Number of rows: 2
• Pitch - mating: 0.100" (2.54mm)
• Row spacing - mating: 0.100" (2.54mm)
• Mounting type: Through hole
• Termination: Solder
• Contact finish - mating: Gold
• Contact finish - post: Tin
• Material flammability rating: UL94 V-0
• Moisture sensitivity level: 1 (Unlimited)

The 3M N3793-2202RB qualifies as a direct substitute based on matching all primary substitution criteria. While minor variations exist in shrouding configuration (3-wall versus 4-wall), contact length specifications, insulation material composition, and maximum operating temperature (105°C versus 125°C), these differences do not preclude functional equivalence in applications where the substitute's specifications remain within acceptable design tolerances.

Parameter Comparison

Engineering Selection Recommendations

Both the HARTING 09185107912 and 3M N3793-2202RB are active products with equivalent compliance certifications. The HARTING part maintains a higher maximum operating temperature specification of 125°C compared to the 3M substitute's 105°C rating. The 3M N3793-2202RB provides a specified current rating of 1.75A per contact, whereas the HARTING part does not include this specification in available documentation.

Selection between these parts should be based on application-specific temperature requirements and current handling needs. For applications operating consistently below 105°C, the 3M substitute provides functional equivalence with documented current capacity. For applications requiring the full -55°C to 125°C temperature range, the HARTING part is the appropriate choice. Both parts meet UL94 V-0 flammability requirements and maintain unlimited moisture sensitivity classification, ensuring suitability for standard PCB assembly and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can the 3M N3793-2202RB be used as a direct replacement for the HARTING 09185107912?

A: The 3M N3793-2202RB qualifies as a functional equivalent for applications where the maximum operating temperature does not exceed 105°C. Both connectors share identical pitch, position count, row configuration, contact type, and termination method. Verify that your application's thermal requirements fall within the 3M part's -55°C to 105°C operating range before substitution.

Q: What is the significance of the shrouding difference between 4-wall and 3-wall configurations?

A: The HARTING part features 4-wall shrouding, while the 3M substitute provides 3-wall shrouding. This difference affects mechanical protection and EMI shielding characteristics. Evaluate your application's mechanical stress and electromagnetic environment to determine if the reduced shrouding of the 3M part remains acceptable.

Q: Are there differences in contact length that affect PCB layout?

A: Yes. The HARTING 09185107912 has an overall contact length of 0.713" (18.10mm), while the 3M N3793-2202RB measures 0.652" (16.56mm). The post length also differs: 0.177" (4.50mm) for HARTING versus 0.112" (2.84mm) for 3M. These dimensional variations may impact PCB hole depth and solder joint formation. Verify PCB design compatibility before substitution.

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

A: The HARTING part uses polybutylene terephthalate (PBT) glass-filled insulation, while the 3M substitute uses polycyclohexylenedimethylene terephthalate (PCT) polyester glass-filled insulation. Both materials meet UL94 V-0 flammability requirements. PCT offers different thermal and chemical resistance characteristics compared to PBT; consult material datasheets if your application involves exposure to specific chemicals or extreme thermal cycling.

Q: Does the 3M part's specified current rating of 1.75A apply to all 10 positions simultaneously?

A: The 1.75A specification provided for the 3M N3793-2202RB represents the current rating per contact. Total system current capacity depends on the number of simultaneously loaded positions and thermal dissipation conditions. Refer to the 3M connector datasheet for detailed current distribution guidelines and thermal derating curves.

Q: Are both parts RoHS compliant?

A: Yes. The HARTING 09185107912 is ROHS3 compliant, and the 3M N3793-2202RB is RoHS compliant. Both parts meet hazardous substance restrictions for electronic components. REACH status is unaffected for both connectors.
