Key Parameters

Substitute Part Grouping Explanation

The CWR-220-14-0203 qualifies as a direct substitute for the CWR-220-14-0003 based on the following critical parameters:

• Identical connector type, contact type, and position count (14-position receptacle with female sockets)
• Matching pitch and row spacing (0.100" / 2.54mm)
• Identical mounting configuration (free hanging, in-line)
• Same cable termination method (IDC for ribbon cable)
• Matching feed-through feature and blue color
• Same series designation (CWR)

The primary difference between these parts is the contact finish specification: CWR-220-14-0003 uses tin-lead finish while CWR-220-14-0203 uses tin finish. Both finishes are compatible with IDC ribbon cable termination and maintain electrical and mechanical interchangeability for standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both CWR-220-14-0003 and CWR-220-14-0203 are active production parts suitable for 14-position IDC ribbon cable connector applications. Selection between these parts should be based on compliance requirements:

The CWR-220-14-0203 is ROHS3 compliant and should be selected for applications subject to RoHS regulations or where lead-free contact finish is mandated by design specifications. The CWR-220-14-0003 with tin-lead finish is appropriate for applications without RoHS compliance requirements. Both parts maintain identical mechanical and electrical characteristics for standard IDC ribbon cable termination. The CWR-220-14-0203 offers higher inventory availability with 7661 units in stock compared to 1010 units for the primary part number.

Frequently Asked Questions (FAQ)

Q: Are CWR-220-14-0003 and CWR-220-14-0203 mechanically interchangeable?

A: Yes. Both parts share identical connector type, position count, pitch, row spacing, mounting configuration, and feed-through design. They are mechanically interchangeable in all standard applications.

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

A: The CWR-220-14-0003 uses tin-lead finish while the CWR-220-14-0203 uses tin finish. Both finishes are suitable for IDC ribbon cable termination. The tin finish in CWR-220-14-0203 provides RoHS3 compliance, whereas the tin-lead finish in CWR-220-14-0003 does not.

Q: Which part should I select for RoHS-compliant applications?

A: The CWR-220-14-0203 is ROHS3 compliant and must be used for applications requiring RoHS certification or lead-free specifications.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts are electrically equivalent for IDC ribbon cable applications. Electrical performance is determined by the shared connector design, contact type, and pitch specification.

Q: What is the packaging format for both parts?

A: Both CWR-220-14-0003 and CWR-220-14-0203 are supplied in bulk packaging.
