CWN-360-16-0021 Equivalent & Substitute Parts

Part Overview

The CWN-360-16-0021 is a rectangular connector header manufactured by CW Industries, designed for through-hole mounting applications. This 16-position, 2-row connector with 0.100" (2.54mm) pitch serves board-to-cable/wire interconnection in electronic assemblies. The part is currently active in production with full inventory availability (1086 pieces in stock). Substitute parts are identified when original stock is unavailable, when alternative packaging formats are required, or when design specifications permit equivalent electrical and mechanical parameters within the allowed tolerance ranges for this connector category.

Substitute Part Grouping Explanation

Substitution eligibility for the CWN-360-16-0021 is determined by strict equivalence across the following critical parameters:

Connector Type & Contact Configuration: Header with male pins
Position Count & Row Configuration: 16 positions in 2-row arrangement
Mating Pitch & Row Spacing: 0.100" (2.54mm) for both mating pitch and row spacing
Mounting & Termination: Through-hole solder termination
Shrouding Configuration: Shrouded with 4-wall design
Fastening Mechanism: Push-pull fastening type
Flammability & Compliance: UL94 V-0 material rating; RoHS compliance status

The four identified substitute parts (71918-016LF, D3408-6002-AR, N3408-6002RB, N3408-6003RB) meet these core electrical and mechanical requirements. Variations in contact finish thickness, contact material composition, insulation material formulation, and packaging format do not affect functional interchangeability within the allowed parameter ranges for this rectangular connector category.

Engineering Selection Recommendations

All four substitute parts maintain active product status and meet the core electrical and mechanical requirements for direct substitution with the CWN-360-16-0021. Selection among these alternatives is based on the following criteria:

D3408-6002-AR (3M) offers the highest inventory availability (6514 pieces) and maintains ROHS3 compliance matching the original part specification. This part is suitable for applications requiring maximum supply assurance.

71918-016LF (Amphenol ICC/FCI) provides an alternative from a major connector manufacturer with adequate inventory (882 pieces). This part is packaged in tube format, which may be preferred for automated assembly processes.

N3408-6002RB and N3408-6003RB (3M) are both available in bulk packaging with inventory levels of 773 and 977 pieces respectively. These parts differ primarily in contact length specifications (post length 0.112" versus 0.155"), allowing selection based on specific board thickness and mating depth requirements.

All substitute parts carry RoHS compliance certification and MSL 1 rating, confirming compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can 71918-016LF be used as a direct replacement for CWN-360-16-0021?

A: Yes. Both parts share identical connector type, position count, row configuration, mating pitch (0.100"), row spacing (0.100"), mounting method (through-hole), termination (solder), shrouding (4-wall), and fastening type (push-pull). Packaging format differs (tube versus bulk), but this does not affect functional compatibility.

Q: What is the difference between N3408-6002RB and N3408-6003RB?

A: Both parts are electrically and mechanically equivalent. The primary difference is contact post length: N3408-6002RB has 0.112" (2.84mm) post length, while N3408-6003RB has 0.155" (3.94mm) post length. Selection depends on PCB thickness and connector mating depth requirements in your application.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts carry RoHS compliance certification. The original CWN-360-16-0021 is ROHS3 compliant, while substitute parts carry either ROHS3 or RoHS compliance status. Both certifications meet current regulatory requirements.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (bulk, tube, or tray) is a logistics and handling consideration only. It does not affect the electrical or mechanical performance of the connector itself. Selection should be based on your assembly process requirements and inventory management practices.

Q: Can I mix different substitute parts in the same assembly?

A: Yes. All identified substitute parts meet the same electrical and mechanical specifications for the 16-position, 2.54mm pitch header connector category. Mixed usage within a single assembly does not create compatibility issues.

Q: What operating temperature range applies to all substitute parts?

A: The original CWN-360-16-0021 operates from -55°C to 125°C. Substitute parts D3408-6002-AR, N3408-6002RB, and N3408-6003RB operate from -55°C to 105°C. The 71918-016LF does not specify an operating temperature range in the provided data. Verify temperature requirements against your application specifications before final selection.
