Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 1658619-1 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Receptacle
• Number of Positions: 40
• Pitch: 0.100" (2.54mm)
• Number of Rows: 2
• Row Spacing: 0.100" (2.54mm)
• Cable Termination: IDC
• Wire Type: Ribbon Cable
• Contact Finish: Gold
• Mounting Type: Free Hanging (In-Line)
• Features: Feed Through
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The CW Industries CWR-220-40-0000 meets all mandatory matching parameters and qualifies as a direct substitute. Both connectors share identical electrical and mechanical specifications for position count, pitch, row configuration, and termination method. Both are RoHS3 compliant and rated for unlimited moisture sensitivity conditions.

Parameter Comparison

Engineering Selection Recommendations

The CW Industries CWR-220-40-0000 is a qualified substitute for the obsolete TE Connectivity 1658619-1. Both connectors satisfy identical electrical and mechanical requirements for 40-position IDC ribbon cable applications with 0.100" pitch and 2-row configuration.

Compliance Alignment: Both parts are ROHS3 compliant and rated for MSL 1 (Unlimited moisture sensitivity). The substitute part carries Active product status, ensuring ongoing availability and supply chain continuity compared to the obsolete original part.

Operational Compatibility: The connectors are functionally equivalent for feed-through applications with free-hanging in-line mounting. The gold contact finish on both parts provides equivalent electrical performance for IDC termination with ribbon cable.

Specification Variance: The substitute part features a contact finish thickness of 10.0µin (0.25µm) compared to the original 15.0µin (0.38µm). This variance remains within acceptable parameters for IDC connector applications. The housing color differs (Blue versus Black), which does not affect electrical or mechanical function.

Frequently Asked Questions (FAQ)

Q: Can the CW Industries CWR-220-40-0000 directly replace the TE Connectivity 1658619-1 in existing applications?

A: Yes. Both connectors share identical specifications for position count (40), pitch (0.100"), row configuration (2 rows), mounting type (free-hanging in-line), cable termination method (IDC), and wire type (ribbon cable). The connectors are mechanically and electrically compatible for direct substitution.

Q: What is the significance of the contact finish thickness difference?

A: The TE Connectivity part specifies 15.0µin (0.38µm) gold plating while the CW Industries substitute specifies 10.0µin (0.25µm). Both thicknesses are within acceptable ranges for IDC connector applications and do not affect functional compatibility or electrical performance in standard ribbon cable interconnect systems.

Q: Why is product status relevant to this substitution?

A: The original TE Connectivity 1658619-1 is classified as obsolete, indicating discontinued manufacturing and limited future availability. The CW Industries CWR-220-40-0000 maintains Active product status, ensuring reliable procurement and supply chain support for new designs and ongoing system maintenance.

Q: Are there compliance differences between the two parts?

A: No. Both connectors are ROHS3 compliant and rated for MSL 1 (Unlimited). Both carry identical environmental and regulatory compliance classifications, making them suitable for equivalent applications in regulated industries.

Q: Does the housing color difference affect connector function?

A: No. The housing color (Black for the original, Blue for the substitute) is a cosmetic distinction that does not impact electrical performance, mechanical fit, or operational characteristics. Color selection is typically driven by manufacturing or organizational preferences rather than functional requirements.

Q: What parameters must match for a connector to qualify as a substitute?

A: Critical matching parameters include connector type (receptacle), position count (40), pitch (0.100"), row configuration (2 rows), row spacing (0.100"), mounting type (free-hanging in-line), cable termination method (IDC), wire type (ribbon cable), contact finish (gold), and feed-through feature. Compliance ratings (RoHS3, MSL 1) must also align.
