CWN-360-20-0021 Equivalent & Substitute Parts

Part Overview

The CWN-360-20-0021 is a rectangular connector header manufactured by CW Industries, designed for through-hole mounting applications. This shrouded 20-position header with 2.54mm pitch serves board-to-cable/wire interconnection requirements. The part is active in production status with full inventory availability. Substitute parts may be required due to supply constraints, lead time considerations, or specific application requirements where alternative manufacturers' offerings meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWN-360-20-0021 is determined by strict equivalence across the following critical parameters:

• Connector type: Header
• Contact type: Male Pin
• Number of positions: 20
• Number of rows: 2
• Mating pitch: 0.100" (2.54mm)
• Row spacing: 0.100" (2.54mm)
• Mounting type: Through Hole
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Fastening type: Push-Pull
• Material flammability rating: UL94 V-0
• RoHS compliance: ROHS3 Compliant or equivalent
• Moisture sensitivity level: 1 (Unlimited)

The three substitute parts listed—71918-020LF (Amphenol ICC), N3428-6002RB (3M), and N3428-6003RB (3M)—meet all critical substitution criteria. Variations in contact length, insulation height, contact finish materials, and current ratings are within acceptable tolerances for this connector category and do not preclude functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active production items with full RoHS compliance status. The CWN-360-20-0021 and N3428-6003RB share identical contact length specifications (0.155" post length, 0.240" mating length), making N3428-6003RB the closest mechanical equivalent. The 71918-020LF offers an alternative from Amphenol ICC with slightly reduced contact lengths but maintains all critical electrical and mechanical parameters. The N3428-6002RB provides a 3M alternative with different post length characteristics.

Selection between substitutes should be based on availability, lead time requirements, and specific application constraints. All parts maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification. The 3M parts (N3428-6002RB and N3428-6003RB) support higher current ratings (1.75A) compared to the primary part (1A), providing additional margin for applications with elevated current demands.

Frequently Asked Questions (FAQ)

Q: Can 71918-020LF be used as a direct replacement for CWN-360-20-0021?

A: Yes. The 71918-020LF meets all critical substitution parameters: 20-position, 2-row, 2.54mm pitch, shrouded 4-wall header with through-hole solder termination and push-pull fastening. Minor variations in contact length (0.228" vs. 0.240" mating) and insulation height (0.685" vs. 0.681") fall within acceptable tolerances for this connector category.

Q: What are the differences between N3428-6002RB and N3428-6003RB?

A: Both are 3M 3000 series headers with identical electrical specifications. The primary difference is contact post length: N3428-6002RB has 0.112" (2.84mm) post length, while N3428-6003RB has 0.155" (3.94mm) post length, matching the CWN-360-20-0021. Selection depends on PCB thickness and application requirements.

Q: Are there temperature rating differences between substitutes?

A: The CWN-360-20-0021 operates from -55°C to 125°C. The 3M parts (N3428-6002RB and N3428-6003RB) operate from -55°C to 105°C, providing a 20°C lower upper limit. The 71918-020LF does not specify an operating temperature range. Applications requiring operation above 105°C should use the primary CWN-360-20-0021 part.

Q: Do packaging differences affect substitution?

A: The CWN-360-20-0021 is supplied in bulk packaging, while 71918-020LF is supplied in tube packaging. This affects handling and storage but does not impact electrical or mechanical compatibility. N3428-6002RB and N3428-6003RB are supplied in bulk packaging.

Q: Are all substitute parts RoHS compliant?

A: Yes. The CWN-360-20-0021 is ROHS3 compliant. The 71918-020LF is RoHS compliant. The N3428-6002RB and N3428-6003RB are ROHS3 compliant. All parts meet REACH requirements and carry EAR99 ECCN classification.
