Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HARTING 09185405921 are qualified based on strict electrical and mechanical parameter alignment. The following criteria determine substitutability:

Critical Parameters (Must Match Exactly):

• Connector type: Header
• Contact type: Male Pin
• Number of positions: 40
• 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
• Fastening type: Push-Pull
• Termination: Solder
• Contact finish - mating: Gold
• Material flammability rating: UL94 V-0

Acceptable Variations (Within Specification):

• Contact length - mating: Variations within 0.228" to 0.240" (5.80mm to 6.10mm)
• Contact length - post: Variations within 0.112" to 0.177" (2.84mm to 4.50mm)
• Insulation height: Variations within 0.335" to 0.340" (8.51mm to 8.64mm)
• Contact material: Copper Alloy or Phosphor Bronze
• Insulation material: PBT or PCT/Polyester, both glass-filled
• Operating temperature: Minimum -55°C and maximum 105°C or higher
• RoHS/REACH compliance status

The two qualified substitutes—Amphenol ICC (FCI) 71922-040LF and 3M N3432-5002RB—meet all critical parameters and fall within acceptable mechanical tolerances.

Parameter Comparison

Engineering Selection Recommendations

HARTING 09185405921 (Primary Part) Use as the primary selection when SEK series specifications and ROHS3 compliance are required. This part maintains the widest operating temperature range (-55°C to 125°C) and is actively stocked with 669 units available.

Amphenol ICC (FCI) 71922-040LF (Substitute) Select this substitute when Quickie™ series compatibility is acceptable and tube packaging is preferred over bulk. The part meets all critical electrical and mechanical parameters with RoHS compliance. Note that operating temperature range is not specified; verify thermal requirements against application specifications. This part has the highest inventory availability at 938 units.

3M N3432-5002RB (Substitute) Select this substitute when 3000 series connector compatibility is required and the operating temperature range of -55°C to 105°C meets application needs. This part provides specified current rating of 1.75A per contact and is available in bulk packaging with 876 units in stock. Use when REACH-unaffected status is a procurement requirement.

All three parts carry UL94 V-0 flammability certification, MSL 1 rating, and meet solder termination and push-pull fastening requirements for direct functional substitution in board-to-cable/wire applications.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 71922-040LF replace the HARTING 09185405921 in all applications?

A: The Amphenol ICC 71922-040LF meets all critical electrical and mechanical parameters for direct substitution. However, the operating temperature range is not specified in the datasheet. Verify that your application does not require operation above the HARTING part's maximum of 125°C. The contact length post is shorter (0.114" vs. 0.177"), which may affect PCB layout spacing; confirm board design compatibility before substitution.

Q: What is the difference between the contact materials used in these parts?

A: The HARTING and 3M parts use Copper Alloy contacts, while the Amphenol ICC part uses Phosphor Bronze. Both materials are suitable for gold-plated mating surfaces and solder termination. Phosphor Bronze offers enhanced spring characteristics and durability in high-cycle mating applications. Material selection does not affect basic electrical performance for standard board-to-cable interconnection.

Q: Are there packaging differences between these substitutes?

A: Yes. The HARTING 09185405921 and 3M N3432-5002RB are supplied in bulk packaging. The Amphenol ICC 71922-040LF is supplied in tube packaging. Tube packaging may provide better protection during storage and handling but may require different bin organization in manufacturing environments. Confirm packaging compatibility with your assembly process before ordering.

Q: Which substitute should I choose if operating temperature is critical?

A: The HARTING 09185405921 supports -55°C to 125°C. The 3M N3432-5002RB supports -55°C to 105°C. If your application requires operation above 105°C, use the HARTING part. The Amphenol ICC 71922-040LF does not specify an operating temperature range; contact the manufacturer for thermal specifications before use in temperature-critical applications.

Q: Do all three parts meet RoHS compliance?

A: Yes. The HARTING 09185405921 is ROHS3 compliant. The Amphenol ICC 71922-040LF and 3M N3432-5002RB are RoHS compliant. All three parts meet current RoHS requirements and are suitable for applications requiring RoHS certification.

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

A: The HARTING part has a post length of 0.177" (4.50mm), while the Amphenol ICC and 3M parts have post lengths of 0.114" (2.90mm) and 0.112" (2.84mm) respectively. Post length determines solder joint depth on the PCB. Shorter posts may require PCB design adjustment to ensure adequate solder fillet formation. Verify PCB pad design and solder reflow profile compatibility before substitution.

Q: Can these parts be used interchangeably in existing designs without PCB modification?

A: Mechanical compatibility exists for all three parts due to matching pitch, row spacing, and mounting type. However, the variation in contact post length (0.177" vs. 0.112-0.114") may require PCB pad adjustment. Consult your PCB design specifications and solder joint requirements before confirming interchangeability without design changes.
