ADIP18-G-LC Equivalent & Substitute Parts

Part Overview

The ADIP18-G-LC is an 18-position ribbon cable DIP header connector manufactured by Assmann WSW Components. This through-hole mounted connector features IDC (Insulation Displacement Contact) termination and is designed for applications requiring reliable ribbon cable interconnection with 0.050" (1.27mm) cable pitch and 0.100" (2.54mm) board-side pitch spacing.

The ADIP18-G-LC is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADIP18-G-LC is based on strict equivalence of the following critical parameters:

• Connector type: Ribbon Cable, DIP Header
• Position count: 18 positions
• Cable pitch: 0.050" (1.27mm)
• Board-side pitch: 0.100" (2.54mm)
• Row configuration: 2 rows with 0.300" (7.62mm) spacing
• Mounting method: Through Hole
• Termination method: IDC
• Contact finish: Gold
• Color: Black
• All positions loaded

The substitute part 746611-9 (TE Connectivity AMP Connectors) meets all these critical parameters and is therefore electrically and mechanically compatible with the ADIP18-G-LC.

Parameter Comparison

Engineering Selection Recommendations

The 746611-9 manufactured by TE Connectivity AMP Connectors is the qualified substitute for the obsolete ADIP18-G-LC. Both parts are ROHS3 compliant and carry MSL rating of 1 (Unlimited), ensuring equivalent environmental and regulatory compliance.

The primary advantage of selecting 746611-9 is its active product status, which ensures ongoing availability and supply chain support. The connector maintains identical electrical and mechanical specifications, including pitch dimensions, row configuration, and contact finish properties.

Wire gauge specifications differ between the two parts: the ADIP18-G-LC does not specify wire gauge, while the 746611-9 supports 28 AWG stranded or 26-30 AWG solid conductors. This expanded wire gauge range in the substitute part provides additional design flexibility without compromising compatibility.

Frequently Asked Questions (FAQ)

Q: Can 746611-9 be used as a direct replacement for ADIP18-G-LC in existing designs?

A: Yes. Both connectors share identical pitch dimensions (0.050" cable pitch, 0.100" board-side pitch), row spacing (0.300"), mounting type (through hole), and termination method (IDC). The connectors are mechanically and electrically interchangeable.

Q: What is the significance of the product status difference?

A: The ADIP18-G-LC is obsolete, meaning it is no longer manufactured or supported by Assmann WSW Components. The 746611-9 is active, ensuring continued availability, technical support, and supply chain reliability for new production or maintenance applications.

Q: Are there compliance differences between the two parts?

A: No. Both parts are ROHS3 compliant and carry identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited). Regulatory and environmental compliance requirements are equivalent.

Q: Does the wire gauge specification affect substitution compatibility?

A: The wire gauge specification in 746611-9 (28 AWG stranded or 26-30 AWG solid) defines the supported conductor sizes for IDC termination. The ADIP18-G-LC does not specify wire gauge. When substituting, ensure that ribbon cable conductors fall within the 746611-9 specification range to maintain proper IDC contact engagement and electrical performance.

Q: Are the contact finish specifications identical?

A: Yes. Both connectors feature gold contact finish. The ADIP18-G-LC specifies flash thickness, while the 746611-9 specifies 30.0µin (0.76µm) thickness. Both finishes provide equivalent corrosion resistance and electrical conductivity for this connector class.
