CWR-210-20-0003 Equivalent & Substitute Parts

Part Overview

The CWR-210-20-0003 is a 20 position rectangular receptacle connector manufactured by CW Industries. This connector features IDC (Insulation Displacement Contact) termination for ribbon cable applications with tin-lead contact finish. The part is currently active in production with 688 units in stock. Identifying equivalent substitute parts is necessary when the primary part becomes unavailable or when alternative compliance certifications are required for specific applications.

Substitute Part Grouping Explanation

Substitute parts for the CWR-210-20-0003 are identified based on strict electrical and mechanical compatibility criteria. The following parameters must match or be functionally equivalent:

• Connector type: Receptacle
• Contact type: Female Socket
• Number of positions: 20
• Pitch: 0.100" (2.54mm)
• Number of rows: 2
• Row spacing: 0.100" (2.54mm)
• Mounting type: Free Hanging (In-Line)
• Cable termination: IDC
• Wire type: Ribbon Cable
• Features: Feed Through, Strain Relief
• Series: CWR
• Base product number: CWR-210

The CWR-210-20-0203 meets all these criteria. The primary difference is the contact finish specification: the substitute uses tin finish instead of tin-lead finish, and the RoHS compliance status differs accordingly.

Parameter Comparison

Engineering Selection Recommendations

Both the CWR-210-20-0003 and CWR-210-20-0203 are active products from CW Industries with identical mechanical and electrical specifications for connector form, fit, and function. The primary distinction is regulatory compliance status.

The CWR-210-20-0003 carries RoHS non-compliant status with tin-lead contact finish. The CWR-210-20-0203 is ROHS3 compliant with tin contact finish. Selection between these parts should be based on the regulatory requirements of the end application and target market. Applications requiring RoHS3 compliance must use the CWR-210-20-0203. Applications without RoHS compliance requirements may use either part based on availability and supply chain considerations.

Both parts share identical MSL ratings, REACH status, and ECCN classifications. The CWR-210-20-0203 currently has higher inventory availability at 1007 units compared to 688 units for the CWR-210-20-0003.

Frequently Asked Questions (FAQ)

Q: Are the CWR-210-20-0003 and CWR-210-20-0203 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including pitch (0.100"), number of positions (20), row configuration (2 rows), mounting type (free hanging in-line), and physical form factor. They are mechanically interchangeable in applications where the contact finish difference is not a constraint.

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

A: The CWR-210-20-0003 uses tin-lead contact finish with 100.0µin (2.54µm) thickness. The CWR-210-20-0203 uses tin contact finish. This difference affects RoHS compliance status and may impact solder joint characteristics in specific manufacturing processes.

Q: Can I use the CWR-210-20-0203 as a direct replacement for the CWR-210-20-0003?

A: The CWR-210-20-0203 is functionally equivalent for connector form, fit, and function. Selection depends on regulatory compliance requirements. If your application requires RoHS3 compliance, the CWR-210-20-0203 is the appropriate choice. If RoHS compliance is not required, either part may be used based on availability.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the lowest moisture sensitivity classification. Both parts have unlimited shelf life under normal storage conditions without requiring special moisture control measures.

Q: Are both parts currently in production?

A: Yes. Both the CWR-210-20-0003 and CWR-210-20-0203 are active products. The CWR-210-20-0203 has higher current inventory availability at 1007 units versus 688 units for the CWR-210-20-0003.
