CWR-217-10-0003 Equivalent & Substitute Parts

Part Overview

The CWR-217-10-0003 is a 10 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 equivalent parts may be required due to RoHS compliance requirements, inventory availability, or specific application constraints where contact finish specifications differ from the original design.

Substitute Part Grouping Explanation

Substitution eligibility for the CWR-217-10-0003 is determined by the following critical parameters that must remain constant across equivalent parts:

Connector Type & Contact Configuration: Receptacle with female socket contacts
Position Count & Pitch: 10 positions at 0.100" (2.54mm) pitch
Row Configuration: 2 rows with 0.100" (2.54mm) row spacing
Termination Method: IDC (Insulation Displacement Contact) for ribbon cable
Mechanical Features: Feed Through, Polarizing Key, Strain Relief
Mounting Style: Free Hanging (In-Line)
Color: Blue

The primary variable allowing substitution is the Contact Finish specification. The CWR-217-10-0003 uses tin-lead finish, while equivalent parts may use tin finish. This distinction affects RoHS compliance status but does not alter electrical or mechanical compatibility when both finishes meet the application's performance requirements.

Engineering Selection Recommendations

The CWR-217-10-0203 serves as a direct equivalent to the CWR-217-10-0003 for applications where RoHS3 compliance is required. Both parts maintain identical electrical and mechanical specifications across all critical parameters: connector type, contact configuration, position count, pitch, row spacing, mounting style, and IDC termination method.

The distinction between these parts is the contact finish specification. The CWR-217-10-0003 features tin-lead finish and carries RoHS non-compliant status. The CWR-217-10-0203 features tin finish and is ROHS3 compliant. Both parts are Active status products with unlimited moisture sensitivity rating (MSL 1).

Selection between these parts should be based on regulatory and compliance requirements of the end application. For applications subject to RoHS3 regulations or requiring lead-free components, the CWR-217-10-0203 is the appropriate selection. For legacy systems or applications without RoHS compliance constraints, either part is functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Are CWR-217-10-0003 and CWR-217-10-0203 mechanically interchangeable?

A: Yes. Both parts are mechanically identical. They share the same connector type (receptacle), contact configuration (10 female sockets), pitch (0.100"), row spacing (0.100"), mounting style (free hanging in-line), and mechanical features (feed through, polarizing key, strain relief).

Q: What is the difference between tin-lead and tin contact finishes?

A: The CWR-217-10-0003 uses tin-lead finish with 100.0µin (2.54µm) thickness. The CWR-217-10-0203 uses tin finish. This difference affects RoHS compliance classification but does not alter the electrical or mechanical performance of the connector for IDC ribbon cable applications.

Q: Can I use CWR-217-10-0203 as a replacement for CWR-217-10-0003 in existing designs?

A: Yes, provided your application does not have specific requirements for tin-lead contact finish. The CWR-217-10-0203 is electrically and mechanically equivalent and offers the advantage of ROHS3 compliance.

Q: What does IDC termination mean?

A: IDC (Insulation Displacement Contact) termination allows ribbon cable to be connected directly to the connector without stripping insulation. The connector's contacts pierce through the cable insulation to establish electrical connection.

Q: Are both parts available in the same packaging?

A: The CWR-217-10-0003 packaging is not specified in the provided data. The CWR-217-10-0203 is available in Bulk packaging.

Q: What is the moisture sensitivity level (MSL) rating?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity constraints for storage or handling.
