HARTING 09185406921 Equivalent & Substitute Parts

Part Overview

The HARTING 09185406921 is an active rectangular connector header designed for through-hole, right-angle mounting applications. This 40-position, 2-row connector with 0.100" (2.54mm) pitch serves board-to-cable/wire interconnection requirements in industrial and commercial electronics. The connector features shrouded 4-wall construction with push-pull fastening, gold-plated mating contacts, and tin-plated solder posts. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component interchange based on equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HARTING 09185406921 is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (40) and rows (2)
• Mating pitch (0.100" / 2.54mm)
• Row spacing (0.100" / 2.54mm)
• Mounting configuration (Through Hole, Right Angle)
• Shrouding style (Shrouded - 4 Wall)
• Fastening mechanism (Push-Pull)
• Termination method (Solder)
• Contact finish on mating surface (Gold)
• Contact finish on post (Tin)
• Flammability rating (UL94 V-0)

The identified substitute parts—Amphenol ICC (FCI) 71922-040LF and 3M N3432-5002RB—meet these core electrical and mechanical requirements. Variations in contact length, insulation material composition, and operating temperature ranges are secondary parameters that do not preclude substitution when primary functional criteria are satisfied.

Parameter Comparison

Engineering Selection Recommendations

All three connectors—HARTING 09185406921, Amphenol ICC (FCI) 71922-040LF, and 3M N3432-5002RB—maintain active product status and comply with RoHS regulations. Each part carries UL94 V-0 flammability certification and MSL 1 moisture sensitivity rating, indicating equivalent environmental durability.

The HARTING 09185406921 and 3M N3432-5002RB share identical mating contact length (0.240" / 6.10mm), while the Amphenol ICC 71922-040LF provides a slightly shorter mating contact length (0.228" / 5.80mm). This dimensional variance does not affect electrical performance but may influence mechanical fit in applications with tight tolerance requirements.

Operating temperature range differs between the HARTING part (-55°C ~ 125°C) and the 3M part (-55°C ~ 105°C). Applications requiring operation above 105°C should prioritize the HARTING 09185406921 or confirm thermal compatibility with the Amphenol ICC part, for which operating temperature is not specified.

Contact material composition varies: HARTING and 3M use copper alloy, while Amphenol ICC employs phosphor bronze. Both materials are standard for this connector class and do not preclude substitution.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 71922-040LF be used as a direct replacement for the HARTING 09185406921?

A: Yes. Both connectors share identical pitch (0.100" / 2.54mm), position count (40), row configuration (2), mounting type (through-hole right-angle), shrouding (4-wall), fastening mechanism (push-pull), and contact finishes (gold mating, tin post). The primary difference is mating contact length (0.228" vs. 0.240"), which does not affect electrical compatibility in standard applications.

Q: What is the significance of the contact material difference between copper alloy and phosphor bronze?

A: Both materials are acceptable for this connector class. Copper alloy and phosphor bronze provide equivalent electrical conductivity and corrosion resistance when combined with gold plating on mating surfaces. Material selection does not impact substitution eligibility.

Q: Does the 3M N3432-5002RB operate at the same temperature range as the HARTING part?

A: The 3M part operates from -55°C to 105°C, while the HARTING part operates from -55°C to 125°C. For applications requiring sustained operation above 105°C, the HARTING 09185406921 is the appropriate choice. For applications within the -55°C to 105°C range, the 3M part is suitable.

Q: Are there packaging differences between these parts?

A: Yes. The HARTING 09185406921 is supplied in bulk packaging, the Amphenol ICC 71922-040LF in tube packaging, and the 3M N3432-5002RB in bulk packaging. Packaging format does not affect electrical or mechanical performance but may influence procurement logistics and handling procedures.

Q: Do all three connectors meet RoHS compliance requirements?

A: Yes. The HARTING 09185406921 is ROHS3 compliant, while both the Amphenol ICC 71922-040LF and 3M N3432-5002RB are RoHS compliant. All three parts satisfy RoHS regulatory requirements for lead-free construction.

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

A: The HARTING part uses polybutylene terephthalate (PBT), the Amphenol ICC part uses thermoplastic, and the 3M part uses polycyclohexylenedimethylene terephthalate (PCT) with polyester, all glass-filled. These materials provide equivalent mechanical and electrical insulation properties for this connector application.
