HARTING 09185407921 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The HARTING 09185407921 is an active rectangular connector header designed for through-hole, right-angle board-to-cable/wire applications. This 40-position, 2-row connector with 0.100" (2.54mm) pitch and shrouded 4-wall design serves as a standard interconnect component in electronic assemblies. Substitute parts are identified to provide alternative sourcing options while maintaining electrical and mechanical compatibility within the specified parameter constraints.

Substitute Part Grouping Explanation

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

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 configuration (Shrouded - 4 Wall)
Termination method (Solder)
Fastening type (Push-Pull)
Contact shape (Square)
Material flammability rating (UL94 V-0)

The identified substitute parts meet all these core parameters. Variations in contact length, insulation material composition, contact finish specifications, and insulation color do not affect functional interchangeability within the defined electrical and mechanical constraints.

Engineering Selection Recommendations

All three parts maintain active product status and comply with RoHS requirements. Selection between the HARTING 09185407921, Amphenol ICC 71922-040LF, and 3M N3432-5002RB should be based on the following considerations:

The HARTING 09185407921 and 3M N3432-5002RB both specify operating temperature ranges, with HARTING supporting -55°C to 125°C and 3M supporting -55°C to 105°C. Applications requiring operation above 105°C should use the HARTING part. The Amphenol ICC 71922-040LF does not specify an operating temperature range in the provided data.

All parts carry UL94 V-0 flammability ratings and MSL 1 moisture sensitivity levels, indicating equivalent environmental performance. Contact material differs between suppliers: HARTING and 3M use copper alloy, while Amphenol ICC uses phosphor bronze. Both materials are acceptable for the specified electrical and mechanical requirements.

Packaging format varies: HARTING and 3M are supplied in bulk, while Amphenol ICC is supplied in tube packaging. Inventory availability should be verified for production requirements.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 71922-040LF be used as a direct replacement for the HARTING 09185407921?

A: Yes. Both parts meet all critical substitution parameters: 40-position, 2-row configuration with 0.100" (2.54mm) pitch, through-hole right-angle mounting, shrouded 4-wall design, solder termination, and push-pull fastening. Differences in contact material (phosphor bronze vs. copper alloy) and contact finish specifications do not affect functional interchangeability.

Q: What is the temperature limitation when using the 3M N3432-5002RB?

A: The 3M N3432-5002RB is rated for -55°C to 105°C operation. Applications requiring sustained operation above 105°C should use the HARTING 09185407921, which is rated to 125°C.

Q: Does packaging format affect electrical or mechanical performance?

A: No. Packaging format (bulk vs. tube) affects only handling, storage, and supply chain logistics. Electrical and mechanical performance is identical regardless of packaging method.

Q: Are all three parts RoHS compliant?

A: Yes. The HARTING 09185407921 is ROHS3 compliant. Both the Amphenol ICC 71922-040LF and 3M N3432-5002RB are RoHS compliant. All three parts meet RoHS requirements for lead-free construction.

Q: What is the significance of the different insulation colors?

A: Insulation color (gray vs. black) is a visual identifier only and does not affect electrical or mechanical function. Color selection may be driven by manufacturing process or design convention but does not impact interchangeability.

Q: Can these parts be intermixed in the same assembly?

A: Yes. All three parts are mechanically and electrically equivalent within the specified parameter constraints and can be used interchangeably in the same assembly without modification to PCB layout, mating connectors, or electrical design.
