ADIP40-G-LC Equivalent & Substitute Parts

Part Overview

The ADIP40-G-LC is a 40-position ribbon cable DIP header connector manufactured by Assmann WSW Components, designed for IDC (Insulation Displacement Connector) termination in through-hole applications. This connector features a dual-row configuration with 0.100" (2.54mm) board-side pitch and 0.050" (1.27mm) cable pitch, commonly used in legacy computing and industrial equipment interfaces.

The ADIP40-G-LC is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system compatibility, ensure continued availability for repair and maintenance applications, and support legacy equipment that requires this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADIP40-G-LC is determined by strict equivalence across the following critical parameters:

• Connector Type: Must be Ribbon Cable, DIP Header
• Position Count: Must be 40 positions
• Row Configuration: Must be 2 rows
• Cable Pitch: Must be 0.050" (1.27mm)
• Board-Side Pitch: Must be 0.100" (2.54mm)
• Row Spacing: Must be 0.600" (15.24mm)
• Mounting Type: Must be Through Hole
• Cable Termination: Must be IDC
• Contact Finish: Must be Gold
• Feed Through Feature: Must be present

The CWR-130-40-0000 from CW Industries meets all these critical parameters and is classified as an active product with current manufacturing support, making it a direct functional equivalent for the obsolete ADIP40-G-LC.

Parameter Comparison

Engineering Selection Recommendations

The CWR-130-40-0000 is the direct substitute for the ADIP40-G-LC based on complete mechanical and electrical parameter equivalence. The substitute part offers the following advantages:

• Active Product Status: The CWR-130-40-0000 is actively manufactured and supported, ensuring long-term availability and supply chain continuity compared to the obsolete ADIP40-G-LC.
• Regulatory Compliance: The substitute meets ROHS3 compliance requirements, aligning with current environmental and regulatory standards.
• Specified Wire Gauge: The CWR-130-40-0000 explicitly supports 28-30 AWG wire in both stranded and solid configurations, providing clear guidance for cable selection.
• Contact Finish Specification: The substitute provides a defined contact finish thickness of 10.0µin (0.25µm), ensuring consistent electrical performance.
• REACH Compliance: Both parts maintain REACH Unaffected status, confirming compliance with chemical substance regulations.

Frequently Asked Questions (FAQ)

Q: Can the CWR-130-40-0000 be used as a direct replacement for the ADIP40-G-LC in existing designs?

A: Yes. The CWR-130-40-0000 matches all critical mechanical and electrical parameters of the ADIP40-G-LC, including connector type, position count, pitch specifications, mounting type, and cable termination method. Both connectors are gold-plated, feed-through DIP headers with identical row configurations and spacing.

Q: What is the difference in contact finish between these two parts?

A: The ADIP40-G-LC specifies a flash gold finish, while the CWR-130-40-0000 provides a defined thickness of 10.0µin (0.25µm). Both are gold contact finishes suitable for IDC ribbon cable applications. The specified thickness in the substitute part provides consistent electrical contact characteristics.

Q: Does the CWR-130-40-0000 support the same wire gauges as the ADIP40-G-LC?

A: The ADIP40-G-LC does not specify wire gauge requirements. The CWR-130-40-0000 explicitly supports 28-30 AWG wire in both stranded and solid configurations, which is standard for 40-position IDC ribbon cables with 0.050" pitch.

Q: Are there any compliance differences between the original and substitute part?

A: The CWR-130-40-0000 is ROHS3 compliant, while the ADIP40-G-LC does not specify RoHS status. Both parts are REACH Unaffected and carry the same ECCN (EAR99) and HTSUS classifications. The substitute part meets current environmental compliance standards.

Q: Why is the ADIP40-G-LC classified as obsolete?

A: The ADIP40-G-LC is no longer in active production. The CWR-130-40-0000 from CW Industries is the active equivalent, ensuring continued availability and manufacturing support for this connector type.

Q: Are the physical dimensions and mounting footprints identical?

A: Yes. Both connectors share identical board-side pitch (0.100"), cable pitch (0.050"), row spacing (0.600"), and through-hole mounting configuration. The connectors are mechanically interchangeable in PCB designs.
