CWN-502-14-0021 Equivalent & Substitute Parts

Part Overview

The CWN-502-14-0021 is a rectangular connector header manufactured by CW Industries, designed for through-hole, right-angle mounting applications. This 14-position connector operates at 0.100" (2.54mm) pitch with shrouded 4-wall construction and solder termination. The part is Active status and widely used in board-to-cable/wire interconnect applications requiring reliable male pin connections with keying slot features.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part's specifications, enabling direct replacement in compatible applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWN-502-14-0021 is determined by strict alignment of the following critical parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 14
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• 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 substitute part N3314-5002RB from 3M meets these core mechanical and electrical compatibility criteria. Variations in secondary parameters such as contact finish thickness, insulation material composition, fastening mechanism, and current rating do not preclude substitution when the primary mating and mounting characteristics are identical.

Parameter Comparison

Engineering Selection Recommendations

Both CWN-502-14-0021 and N3314-5002RB are Active status products with UL94 V-0 flammability ratings and RoHS compliance. The primary consideration for selection is the operating temperature requirement: the CWN-502-14-0021 supports -55°C to 125°C, while the N3314-5002RB supports -55°C to 105°C. Applications requiring operation above 105°C must use the CWN-502-14-0021.

The N3314-5002RB provides higher current capacity (1.75A versus 1A) and longer post contact length (0.112" versus 0.090"), which may offer advantages in high-current or deep-board-penetration applications. Both parts feature identical mating pitch, row spacing, and gold-plated mating contact finish, ensuring mechanical and electrical compatibility in standard 0.100" (2.54mm) pitch interconnect designs.

Frequently Asked Questions (FAQ)

Q: Can N3314-5002RB directly replace CWN-502-14-0021 in all applications?

A: Direct replacement is possible when operating temperature does not exceed 105°C. The N3314-5002RB is rated to 105°C maximum, while the CWN-502-14-0021 operates to 125°C. Both parts share identical mating pitch (0.100"), row spacing (0.100"), position count (14), and shrouded 4-wall construction, ensuring mechanical compatibility in standard board-to-cable interconnect designs.

Q: What are the key differences between these two parts?

A: The primary differences are operating temperature range (CWN-502-14-0021: -55°C to 125°C; N3314-5002RB: -55°C to 105°C), current rating (1A versus 1.75A), contact post length (0.090" versus 0.112"), fastening mechanism (Latch Lock/Eject Hooks versus Push-Pull), and contact shape (Circular versus Square). Mating characteristics, pitch, and shrouding are identical.

Q: Are both parts RoHS compliant?

A: Yes. The CWN-502-14-0021 is ROHS3 Compliant, and the N3314-5002RB is RoHS Compliant. Both meet REACH Unaffected status and carry UL94 V-0 flammability ratings.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts have Moisture Sensitivity Level (MSL) 1, indicating Unlimited shelf life without special moisture control requirements.

Q: Does the difference in contact shape (Circular versus Square) affect compatibility?

A: Contact shape differences do not affect mating compatibility when both parts maintain identical pitch (0.100"), row spacing (0.100"), and mating contact length (0.240"). The shape variation is a manufacturing design difference that does not impact electrical or mechanical interconnection in standard applications.
