Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWN-552-20-0000 is determined by the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Row Configuration: 20 positions arranged in 2 rows
• Pitch Specification: 0.100" (2.54mm) mating pitch and row spacing
• Mounting & Termination: Through-hole solder termination
• Shrouding: 4-wall shrouded design
• Regulatory Compliance: ROHS3 compliance and UL94 V-0 flammability rating

The substitute part N3428-6002RB from 3M meets these core electrical and mechanical criteria, enabling direct functional replacement in applications where the specified parameters are required.

Parameter Comparison

Engineering Selection Recommendations

Both CWN-552-20-0000 and N3428-6002RB are active production components with ROHS3 compliance and UL94 V-0 flammability certification. The N3428-6002RB substitute provides higher current rating capability (1.75A versus 1A) and operates within a -55°C to 105°C temperature range, which covers most standard industrial applications. Selection between these parts should be based on specific application current requirements and maximum operating temperature constraints. Both parts maintain identical pitch, position count, and shrouding specifications, ensuring mechanical and electrical compatibility in standard 2.54mm header applications.

Frequently Asked Questions (FAQ)

Q: Can N3428-6002RB replace CWN-552-20-0000 in all applications?

A: N3428-6002RB is functionally equivalent for applications operating within -55°C to 105°C. Applications requiring operation above 105°C must use CWN-552-20-0000, which is rated to 125°C.

Q: What are the key compatibility factors between these parts?

A: Both parts share identical mating pitch (0.100"/2.54mm), row spacing (0.100"/2.54mm), position count (20), row configuration (2 rows), shrouding design (4-wall), and termination method (solder). These parameters ensure direct mechanical and electrical compatibility.

Q: How do the current ratings differ?

A: CWN-552-20-0000 is rated for 1A per contact, while N3428-6002RB is rated for 1.75A per contact. Applications requiring higher current capacity benefit from the N3428-6002RB substitute.

Q: Are both parts RoHS compliant?

A: Yes, both CWN-552-20-0000 and N3428-6002RB are ROHS3 compliant and carry UL94 V-0 flammability certification.

Q: What is the difference in contact material?

A: CWN-552-20-0000 uses phosphor bronze contacts, while N3428-6002RB uses copper alloy contacts. Both materials provide reliable electrical performance with gold mating surface finish.

Q: Do packaging differences affect component selection?

A: CWN-552-20-0000 is available in standard packaging, while N3428-6002RB is supplied in bulk packaging. Packaging format does not affect electrical or mechanical performance.
