Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWN-361-40-0021 is determined by strict alignment of 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
• Termination: Solder
• Shrouding: Shrouded - 4 Wall
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant or RoHS Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All three substitute parts meet these core substitution criteria. Variations in contact shape, contact finish materials, fastening type, and insulation material do not preclude substitution when the primary electrical and mechanical interface parameters are identical.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products with full RoHS compliance and MSL 1 rating, meeting the core substitution criteria for the CWN-361-40-0021.

CWN-361-40-0021 (CW Industries): Primary specification. Circular contact geometry with phosphor bronze material. Operating temperature range -55°C to 125°C. Current rating 1A. Latch lock/eject fastening type.

09185407924 (HARTING): Equivalent substitute with matching operating temperature range (-55°C to 125°C). Square contact geometry with copper alloy material. Push-pull fastening type. ROHS3 compliant. Inventory: 835 pcs.

71918-040LF (Amphenol ICC): Equivalent substitute with square contact geometry and phosphor bronze material. Push-pull fastening type with mounting flange. RoHS compliant. Inventory: 1395 pcs (highest availability).

N3432-6002RB (3M): Equivalent substitute with higher current rating (1.75A) and square contact geometry. Operating temperature range -55°C to 105°C (5°C lower maximum than primary part). Push-pull fastening type with mounting flange. RoHS compliant. Inventory: 791 pcs.

Selection between substitutes depends on application requirements for fastening type, contact geometry preference, current capacity, and maximum operating temperature tolerance.

Frequently Asked Questions (FAQ)

Q: Can the 09185407924 (HARTING) replace the CWN-361-40-0021 in all applications?

A: Yes, the 09185407924 meets all core substitution parameters: 40-position, 2-row, 2.54mm pitch header with through-hole solder termination and shrouded 4-wall construction. Both parts share identical operating temperature range (-55°C to 125°C) and UL94 V-0 flammability rating. The primary difference is fastening type (push-pull versus latch lock/eject) and contact geometry (square versus circular).

Q: What is the difference between the 71918-040LF and N3432-6002RB substitutes?

A: Both are equivalent substitutes with square contact geometry and push-pull fastening. The N3432-6002RB has a higher current rating (1.75A versus unspecified for 71918-040LF) but a lower maximum operating temperature (105°C versus unspecified for 71918-040LF). The 71918-040LF offers higher inventory availability (1395 pcs).

Q: Does contact shape (circular versus square) affect substitution compatibility?

A: Contact shape does not affect electrical or mechanical interface compatibility for these 2.54mm pitch headers. The mating pitch, row spacing, number of positions, and mounting method remain identical. Contact shape is a design variation that does not preclude substitution.

Q: Are all substitute parts RoHS compliant?

A: Yes. The CWN-361-40-0021 is ROHS3 compliant. The 09185407924 is also ROHS3 compliant. The 71918-040LF and N3432-6002RB are RoHS compliant. All parts meet RoHS requirements.

Q: What packaging formats are available for these substitutes?

A: CWN-361-40-0021 packaging is not specified. 09185407924 is supplied in bulk packaging. 71918-040LF is supplied in tube packaging. N3432-6002RB is supplied in bulk packaging. Packaging format should be confirmed with supplier based on procurement requirements.

Q: Can the N3432-6002RB be used in applications requiring the full -55°C to 125°C operating range?

A: The N3432-6002RB has a maximum operating temperature of 105°C, which is 20°C lower than the CWN-361-40-0021 specification of 125°C. Use of the N3432-6002RB is limited to applications with maximum operating temperature of 105°C or below.
