CWN-552-60-0021 Equivalent & Substitute Parts

Part Overview

The CWN-552-60-0021 is a rectangular connector header manufactured by CW Industries, designed for through-hole mounting applications. This 60-position, 2-row connector operates at 0.100" (2.54mm) pitch and is rated for 1A current at operating temperatures from -55°C to 125°C. The connector features shrouded 4-wall construction with solder termination and latch lock/eject hooks for secure mating. As an active product with ROHS3 compliance and UL94 V-0 flammability rating, substitute parts may be required due to inventory constraints, application-specific requirements, or design optimization needs.

• Operating Temperature: -55°C ~ 105°C (lower maximum acceptable if application operates within this range)
• Fastening Type: Push-Pull (alternative to Latch Lock/Eject Hooks)
• Contact Shape: Square (alternative to Circular)
• Contact Finish - Post: Tin (alternative to Nickel)
• Insulation Material: PCT/Polyester/Glass Filled (alternative to Thermoplastic)
• Insulation Color: Black (alternative to Blue)

Parameter Comparison

Engineering Selection Recommendations

Both the CWN-552-60-0021 and N3372-6002RB are active products with equivalent regulatory compliance. The CWN-552-60-0021 supports a higher maximum operating temperature of 125°C compared to the N3372-6002RB at 105°C. Applications requiring operation above 105°C must use the CWN-552-60-0021. The N3372-6002RB provides higher current capacity at 1.75A versus 1A, suitable for applications with elevated current demands within the -55°C to 105°C operating range. Both connectors maintain UL94 V-0 flammability ratings and RoHS compliance. Selection between these parts depends on specific application temperature and current requirements within the stated operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the N3372-6002RB replace the CWN-552-60-0021 in all applications?

A: The N3372-6002RB is compatible for applications operating within -55°C to 105°C. Applications requiring operation above 105°C must use the CWN-552-60-0021.

Q: What are the key dimensional differences between these connectors?

A: Contact length at mating is identical at 0.240" (6.10mm). Insulation height differs minimally: CWN-552-60-0021 at 0.681" (17.30mm) versus N3372-6002RB at 0.680" (17.27mm). Contact length at post differs: CWN-552-60-0021 at 0.090" (2.29mm) versus N3372-6002RB at 0.112" (2.84mm).

Q: Are both connectors suitable for high-reliability applications?

A: Both connectors meet UL94 V-0 flammability requirements and maintain ROHS3/RoHS compliance. Both have MSL rating of 1 (Unlimited) and REACH Unaffected status, suitable for regulated applications.

Q: What is the difference in fastening mechanisms?

A: The CWN-552-60-0021 uses Latch Lock/Eject Hooks with long fastening type. The N3372-6002RB uses Push-Pull fastening. Both provide secure mating but differ in engagement method.

Q: Can these connectors be used interchangeably in board-to-board applications?

A: Both connectors support board-to-board or board-to-cable/wire configurations with identical 60-position, 2-row, 2.54mm pitch specifications. Physical form factor compatibility depends on PCB layout and mating connector design.
