Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWN-512-10-0021 is determined by strict equivalence across the following critical parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 10
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole, Right Angle
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Material Flammability Rating: UL94 V-0

The identified substitute parts 71922-010LF (Amphenol ICC/FCI) and N3793-5002RB (3M) meet all critical substitution criteria. Variations in secondary parameters such as contact length, fastening type, insulation material composition, and contact finish thickness do not preclude functional equivalence in standard applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and comply with UL94 V-0 flammability requirements and MSL 1 moisture sensitivity classification. Selection between the CWN-512-10-0021 and its substitutes should be based on the following considerations:

CWN-512-10-0021 (CW Industries): Primary choice for applications requiring ROHS3 compliance and REACH unaffected status. Specified operating temperature range of -55°C to 125°C and 1A current rating are documented. Circular contact geometry and phosphor bronze material provide established performance characteristics.

71922-010LF (Amphenol ICC/FCI Quickie™ Series): Suitable for applications where REACH affected status is acceptable. Push-pull fastening type differs from the latch lock/eject hooks of the primary part. Operating temperature and current rating are not specified in available data. Square contact geometry and glass-filled thermoplastic insulation are provided.

N3793-5002RB (3M 3000 Series): Applicable for applications requiring higher current capacity (1.75A) within a -55°C to 105°C operating range. REACH unaffected status matches the primary part. Copper alloy contact material and enhanced insulation material composition (PCT/Polyester/Glass Filled) are specified. Push-pull fastening type and square contact geometry differ from the primary part.

Frequently Asked Questions (FAQ)

Q: Can 71922-010LF be used as a direct replacement for CWN-512-10-0021?

A: The 71922-010LF meets all critical substitution parameters including connector type, pitch, position count, row configuration, mounting type, and shrouding. However, fastening type differs (push-pull versus latch lock/eject hooks), and operating temperature and current rating are not specified. Application-specific requirements must be evaluated.

Q: What is the primary difference between the contact shapes in these parts?

A: The CWN-512-10-0021 features circular contacts, while both substitute parts (71922-010LF and N3793-5002RB) use square contacts. Both geometries are compatible with standard 2.54mm pitch mating connectors and do not affect electrical or mechanical interchangeability in typical applications.

Q: Does the N3793-5002RB have a higher current rating than the primary part?

A: Yes. The N3793-5002RB is rated for 1.75A compared to the 1A rating of the CWN-512-10-0021. This higher rating may be advantageous for applications with elevated current requirements, provided the operating temperature range of -55°C to 105°C is acceptable.

Q: Are there compliance differences between these parts?

A: All three parts are RoHS compliant and UL94 V-0 rated. The CWN-512-10-0021 and N3793-5002RB are REACH unaffected, while the 71922-010LF is REACH affected. The primary part carries ROHS3 compliance, while the substitutes carry RoHS compliance. Application regulatory requirements must be confirmed.

Q: What packaging formats are available?

A: The CWN-512-10-0021 is supplied in bulk packaging. The 71922-010LF is supplied in tube packaging. The N3793-5002RB is supplied in bulk packaging. Packaging format may affect procurement logistics and handling procedures.

Q: Can these parts be used interchangeably in high-temperature applications?

A: The CWN-512-10-0021 supports -55°C to 125°C operation. The N3793-5002RB supports -55°C to 105°C operation. The 71922-010LF operating temperature is not specified. Applications requiring operation above 105°C should use the primary part or confirm substitute suitability through manufacturer documentation.
