Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CWN-352-16-0021 are qualified based on the following critical parameters that must remain constant or compatible:

• Connector Type & Contact Type: All substitutes must be headers with male pins
• Position Count & Row Configuration: 16 positions in 2-row arrangement
• Pitch Specifications: Mating pitch and row spacing both 0.100" (2.54mm)
• Mounting & Termination: Through-hole solder termination required
• Shrouding: 4-wall shrouded configuration
• Flammability & Compliance: UL94 V-0 material rating and RoHS compliance

The following parts meet these core substitution criteria:

1. 71918-016LF (Amphenol ICC / FCI, Quickie™ Series)
2. D3408-6002-AR (3M, D3000 Series)
3. N3408-6002RB (3M, 3000 Series)
4. N3408-6003RB (3M, 3000 Series)

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and meet UL94 V-0 flammability requirements with RoHS compliance. Selection between the CWN-352-16-0021 and qualified substitutes depends on specific application constraints:

CWN-352-16-0021 (CW Industries): Supports the full operating temperature range of -55°C to 125°C with 1A current rating. Circular contact geometry with phosphor bronze material and nickel post finish. ROHS3 compliant.

71918-016LF (Amphenol ICC / FCI): Quickie™ series with square contact geometry and GXT™ gold mating finish. Operating temperature range not specified. Current rating not specified. RoHS compliant. Packaged in tubes.

D3408-6002-AR (3M): D3000 series with higher current rating of 1.75A. Operating temperature limited to -55°C to 105°C. Brass contact material with tin post finish. ROHS3 compliant. Packaged in trays. Includes overall contact length specification of 0.652" (16.56mm).

N3408-6002RB (3M): 3000 series with 1.75A current rating and -55°C to 105°C operating range. Copper alloy contact material with tin post finish. RoHS compliant. Bulk packaging. Overall contact length 0.652" (16.56mm).

N3408-6003RB (3M): 3000 series with 1.75A current rating and -55°C to 105°C operating range. Copper alloy contact material with tin post finish. RoHS compliant. Bulk packaging. Extended post length of 0.155" (3.94mm) with overall contact length of 0.695" (17.65mm).

Frequently Asked Questions (FAQ)

Q: Can 71918-016LF be used as a direct replacement for CWN-352-16-0021?

A: The 71918-016LF meets all core substitution criteria: 16-position, 2-row header with 0.100" pitch, through-hole solder termination, 4-wall shrouding, and UL94 V-0 rating. However, operating temperature range and current rating are not specified for this part. Contact geometry differs (square vs. circular), and contact finish materials vary (tin post vs. nickel post). Compatibility depends on application-specific thermal and electrical requirements.

Q: What are the key differences between the 3M substitute options?

A: N3408-6002RB and N3408-6003RB are both 3M 3000 series parts with identical electrical specifications (1.75A, -55°C to 105°C). The primary difference is post length: N3408-6002RB has 0.112" (2.84mm) post length with 0.652" (16.56mm) overall contact length, while N3408-6003RB has 0.155" (3.94mm) post length with 0.695" (17.65mm) overall contact length. Selection depends on PCB thickness and assembly requirements. D3408-6002-AR is the tray-packaged variant of the same electrical specification.

Q: Are there temperature limitations when substituting with 3M parts?

A: Yes. The CWN-352-16-0021 operates from -55°C to 125°C, while all 3M substitute parts (D3408-6002-AR, N3408-6002RB, N3408-6003RB) are rated only to 105°C maximum. Applications requiring operation above 105°C are not compatible with these 3M substitutes.

Q: How do contact material differences affect substitution?

A: The CWN-352-16-0021 uses phosphor bronze contacts with nickel post finish. Substitute parts use either phosphor bronze (71918-016LF), brass (D3408-6002-AR), or copper alloy (N3408-6002RB, N3408-6003RB) with tin post finish. These material variations affect electrical conductivity, corrosion resistance, and solderability. Substitution is valid within the defined parameter set, but material-specific performance characteristics should be evaluated for critical applications.

Q: What packaging options are available?

A: CWN-352-16-0021 packaging is not specified. Substitute parts are available in tube (71918-016LF), tray (D3408-6002-AR), and bulk (N3408-6002RB, N3408-6003RB) packaging. Packaging selection affects handling, storage, and assembly process integration.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts meet RoHS compliance requirements. The CWN-352-16-0021 and D3408-6002-AR are ROHS3 compliant. The 71918-016LF, N3408-6002RB, and N3408-6003RB are RoHS compliant. Both compliance levels are acceptable for RoHS-regulated applications.
