CWR-217-50-0003 Equivalent & Substitute Parts

Part Overview

The CWR-217-50-0003 is a 50-position rectangular receptacle connector manufactured by CW Industries, designed for IDC (Insulation Displacement Contact) termination with ribbon cable applications. This connector features tin-lead contact finish and is classified as Active product status. Alternative models become necessary when specific compliance requirements, packaging formats, or contact finish specifications differ from the original design parameters, particularly regarding RoHS compliance and contact material composition.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWR-217-50-0003 is determined by the following critical parameters that must remain constant:

• Connector Type: Receptacle
• Number of Positions: 50
• Pitch: 0.100" (2.54mm)
• Number of Rows: 2
• Row Spacing: 0.100" (2.54mm)
• Cable Termination: IDC
• Wire Type: Ribbon Cable
• Features: Feed Through, Polarizing Key, Strain Relief
• Series: CWR

The primary variable parameter permitting substitution is Contact Finish composition (tin-lead versus tin), which affects RoHS compliance status and contact material specifications without altering the mechanical or electrical interface characteristics. The CWR-217-50-0203 qualifies as a direct substitute based on identical mechanical and electrical parameters with modified contact finish material.

Parameter Comparison

Engineering Selection Recommendations

Selection between CWR-217-50-0003 and CWR-217-50-0203 is determined by regulatory and compliance requirements:

CWR-217-50-0003 is appropriate for applications where RoHS non-compliance is acceptable or where legacy tin-lead contact specifications are required. This part maintains Active product status with unlimited moisture sensitivity level (MSL 1).

CWR-217-50-0203 is the required selection for applications subject to ROHS3 compliance mandates. This substitute provides identical mechanical and electrical interface characteristics while eliminating lead from the contact finish composition. Both parts maintain Active product status and identical REACH and ECCN classifications.

The substitution is mechanically and electrically transparent, with the primary distinction being contact material composition and resulting regulatory compliance profile.

Frequently Asked Questions (FAQ)

Q: Are CWR-217-50-0003 and CWR-217-50-0203 mechanically interchangeable?

A: Yes. Both connectors share identical pitch (0.100"), position count (50), row configuration (2 rows), mounting type (free hanging in-line), and feature set (feed through, polarizing key, strain relief). Physical dimensions and mating interfaces are equivalent.

Q: What is the primary difference between these two parts?

A: The contact finish material differs. CWR-217-50-0003 uses tin-lead finish and is RoHS non-compliant. CWR-217-50-0203 uses tin finish and is ROHS3 compliant. All other electrical and mechanical parameters remain identical.

Q: Can CWR-217-50-0203 replace CWR-217-50-0003 in existing designs?

A: Yes, provided the application does not specifically require tin-lead contact composition. The substitute maintains all electrical performance characteristics and mechanical compatibility. Verify that ROHS3 compliance aligns with your application requirements.

Q: What packaging formats are available?

A: CWR-217-50-0003 is supplied in standard packaging. CWR-217-50-0203 is available in Bulk packaging format.

Q: Are both parts currently in production?

A: Yes. Both CWR-217-50-0003 and CWR-217-50-0203 maintain Active product status with CW Industries.
