CWN-552-10-0021 Equivalent & Substitute Parts

Part Overview

The CWN-552-10-0021 is a rectangular connector header manufactured by CW Industries, designed for through-hole mounting applications. This shrouded 10-position header with 2.54mm pitch serves board-to-cable/wire interconnection requirements. The part is currently active in production with 1182 units in stock. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component selection from qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWN-552-10-0021 is determined by the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions and rows (10 positions, 2 rows)
• Pitch specification (0.100" / 2.54mm mating pitch and row spacing)
• Mounting method (Through Hole)
• Termination type (Solder)
• Shrouding configuration (Shrouded - 4 Wall)
• Style (Board to Cable/Wire or Board to Board)
• Material flammability rating (UL94 V-0)

All three substitute parts meet these core criteria. Variations in contact shape, fastening type, contact finish thickness, and insulation material composition do not preclude substitution when electrical and mechanical interface requirements are satisfied.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products with current manufacturing status and full RoHS compliance. Selection among CWN-552-10-0021, 71918-010LF, D3793-6002-AR, and N3793-6002RB is based on the following factors:

CWN-552-10-0021 (Primary Part): ROHS3 compliant with extended operating temperature range (-55°C to 125°C) and 1A current rating. Phosphor bronze contact material with circular contact geometry.

71918-010LF (Amphenol ICC): RoHS compliant with square contact geometry and push-pull fastening. Insulation material includes glass-filled thermoplastic. Operating temperature and current rating not specified in available data.

D3793-6002-AR (3M): ROHS3 compliant with higher current rating (1.75A) and operating temperature range of -55°C to 105°C. Brass contact material with square geometry and mounting flange feature. Tray packaging.

N3793-6002RB (3M): RoHS compliant with 1.75A current rating and -55°C to 105°C operating temperature. Copper alloy contact material with square geometry and mounting flange. Bulk packaging. Supports board-to-board or cable connection styles.

For applications requiring the full -55°C to 125°C temperature range, CWN-552-10-0021 is the appropriate selection. For applications with lower temperature requirements and higher current demands, D3793-6002-AR or N3793-6002RB provide suitable alternatives with enhanced current capacity.

Frequently Asked Questions (FAQ)

Q: Can 71918-010LF replace CWN-552-10-0021 in all applications?

A: 71918-010LF meets the core mechanical and electrical interface requirements (10-position, 2-row, 2.54mm pitch, shrouded header, through-hole solder termination). However, operating temperature and current rating specifications are not provided for 71918-010LF. Applications requiring the full -55°C to 125°C temperature range or specific current ratings should reference the primary part or the 3M alternatives.

Q: What is the difference between D3793-6002-AR and N3793-6002RB?

A: Both parts are 3M rectangular connectors with identical electrical and mechanical specifications (10-position, 2-row, 2.54mm pitch, -55°C to 105°C operating range, 1.75A current rating). Primary differences are packaging format (D3793-6002-AR in tray, N3793-6002RB in bulk) and contact finish thickness on the post (D3793-6002-AR: 39.4µin, N3793-6002RB: 200.0µin). N3793-6002RB explicitly supports board-to-board or cable connection styles.

Q: Are contact shape differences (circular vs. square) significant for substitution?

A: Contact shape differences do not affect mechanical or electrical compatibility when mating pitch, row spacing, and connector geometry remain constant. The circular contact of CWN-552-10-0021 and square contacts of substitute parts are functionally equivalent for standard 2.54mm pitch applications.

Q: Which substitute part has the highest current capacity?

A: D3793-6002-AR and N3793-6002RB both provide 1.75A current rating, compared to 1A for CWN-552-10-0021. These parts are suitable for applications requiring higher current capacity within the -55°C to 105°C operating range.

Q: What packaging options are available?

A: CWN-552-10-0021 packaging is not specified. 71918-010LF is supplied in tube packaging, D3793-6002-AR in tray, and N3793-6002RB in bulk. Packaging selection depends on assembly process requirements and inventory management practices.

Q: Are all substitute parts RoHS compliant?

A: All parts meet RoHS requirements. CWN-552-10-0021 and D3793-6002-AR are ROHS3 compliant. 71918-010LF and N3793-6002RB are RoHS compliant. ROHS3 compliance provides additional restrictions on certain substances compared to standard RoHS compliance.
