CWN-511-14-0021 Equivalent & Substitute Parts

Part Overview

The CWN-511-14-0021 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.

Identifying equivalent and substitute parts is necessary when the primary part experiences supply constraints, inventory limitations, or when design flexibility permits component standardization across manufacturing batches or product revisions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWN-511-14-0021 is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Must be Header with Male Pin contacts
• Position Count & Row Configuration: Must be 14 positions in 2 rows
• Pitch Specifications: Mating pitch and row spacing must both be 0.100" (2.54mm)
• Mounting & Termination: Must support through-hole, right-angle mounting with solder termination
• Shrouding: Must maintain shrouded 4-wall construction
• Style: Must support board-to-cable/wire interconnect applications
• Compliance: Must maintain UL94 V-0 flammability rating and RoHS compliance

The substitute part N3314-5002RB by 3M meets all critical substitution criteria. Both parts share identical position counts, pitch specifications, mounting orientation, shrouding design, and termination method. Both are Active status products with equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both CWN-511-14-0021 and N3314-5002RB are Active status products with UL94 V-0 flammability certification and RoHS compliance, establishing baseline engineering suitability for equivalent applications.

The N3314-5002RB substitute part demonstrates higher current capacity (1.75A versus 1A) and maintains identical mating contact length and pitch specifications. However, the following parameter variations require evaluation against specific application requirements:

• Operating Temperature: CWN-511-14-0021 supports -55°C to 125°C; N3314-5002RB supports -55°C to 105°C. Applications requiring operation above 105°C must use the primary part.
• Contact Post Length: N3314-5002RB post length is 0.043" (1.10mm) shorter. PCB layout and solder joint geometry must accommodate this difference.
• Insulation Height: N3314-5002RB insulation height is 0.010" (0.25mm) shorter. Board-level clearance and mating interface geometry must be verified.
• Contact Geometry & Material: Contact shape differs (circular versus square) and base materials differ (phosphor bronze versus copper alloy). These variations do not preclude substitution but should be documented in design change records.

Selection between these parts is determined by application-specific thermal requirements, PCB layout constraints, and compliance documentation needs.

Frequently Asked Questions (FAQ)

Q: Can N3314-5002RB replace CWN-511-14-0021 in all applications?

A: Substitution is valid for applications operating within -55°C to 105°C temperature range. Applications requiring operation above 105°C must use CWN-511-14-0021. PCB layout must accommodate the 0.043" shorter post length and 0.010" shorter insulation height of the N3314-5002RB.

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

A: Critical differences include operating temperature upper limit (125°C versus 105°C), contact post length (0.155" versus 0.112"), insulation height (0.350" versus 0.340"), contact shape (circular versus square), and contact material (phosphor bronze versus copper alloy). Mating pitch, position count, mounting type, and shrouding are identical.

Q: Are both parts RoHS compliant?

A: Yes. CWN-511-14-0021 is ROHS3 Compliant; N3314-5002RB is RoHS Compliant. Both meet RoHS requirements.

Q: Does the higher current rating of N3314-5002RB affect compatibility?

A: No. The 1.75A rating of N3314-5002RB exceeds the 1A requirement of CWN-511-14-0021, providing additional margin. This does not create compatibility issues in applications designed for 1A operation.

Q: What packaging is available for each part?

A: CWN-511-14-0021 packaging is not specified in available data. N3314-5002RB is supplied in Bulk packaging.

Q: Are there keying features on both parts?

A: CWN-511-14-0021 includes a keying slot. N3314-5002RB includes both keying slot and mounting flange features.
