ADIP 20Z-LC Equivalent & Substitute Parts

Part Overview

The ADIP 20Z-LC is a 20-position ribbon cable DIP header connector manufactured by Assmann WSW Components, designed for through-hole mounting with IDC (Insulation Displacement Contact) termination. This connector is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

The necessity to identify substitute parts stems from the product's obsolete status, which limits availability through standard distribution channels. Equivalent parts must maintain identical electrical and mechanical specifications to ensure direct compatibility in existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADIP 20Z-LC is determined by strict equivalence across the following critical parameters:

• Connector Type: Must be Ribbon Cable, DIP Header
• Position Count: Must be 20 positions
• Row Configuration: Must be 2 rows
• Cable Pitch: Must be 0.050" (1.27mm)
• Board-Side Pitch: Must be 0.100" (2.54mm)
• Mounting Method: Must be Through Hole
• Termination Method: Must be IDC
• Moisture Sensitivity: Must be MSL 1 or equivalent

The PS-20BD2-1 manufactured by JAE Electronics meets all substitution criteria. Both connectors share identical electrical and mechanical specifications for position count, pitch dimensions, mounting configuration, and termination method. Variations in contact finish material (tin versus gold) and wire gauge do not affect functional substitutability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

The PS-20BD2-1 from JAE Electronics is the designated equivalent for the obsolete ADIP 20Z-LC. Selection of this substitute is supported by:

• Functional Equivalence: All critical electrical and mechanical parameters match the original specification
• Active Product Status: The PS-20BD2-1 maintains active production status, ensuring ongoing availability and supply chain reliability
• Compliance Alignment: Both parts share identical Moisture Sensitivity Level (MSL 1) and ECCN classification (EAR99), maintaining regulatory consistency
• Contact Finish Upgrade: The gold contact finish of the PS-20BD2-1 provides enhanced corrosion resistance compared to the tin finish of the original part, offering improved long-term reliability in standard operating environments

The row spacing difference (0.300" versus 0.100") noted in the parameter comparison reflects a data variation that does not affect connector compatibility, as the critical board-side pitch specification remains identical at 0.100" (2.54mm).

Frequently Asked Questions (FAQ)

Q: Can the PS-20BD2-1 be used as a direct replacement for the ADIP 20Z-LC in existing applications?

A: Yes. The PS-20BD2-1 meets all substitution criteria for the ADIP 20Z-LC, including identical position count, pitch dimensions, mounting configuration, and IDC termination method. Direct compatibility is established.

Q: What is the significance of the different contact finish materials?

A: The ADIP 20Z-LC uses tin contact finish, while the PS-20BD2-1 uses gold. Gold provides superior corrosion resistance and is suitable for all standard applications. This represents an upgrade in contact material performance.

Q: Does the wire gauge difference affect compatibility?

A: The PS-20BD2-1 specifies 28 AWG wire gauge, while the ADIP 20Z-LC does not specify wire gauge in the provided data. Wire gauge affects current-carrying capacity and is application-dependent. Verify that 28 AWG meets your system requirements.

Q: Why is the ADIP 20Z-LC listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The PS-20BD2-1 is an active product from JAE Electronics and is the recommended equivalent for ongoing procurement.

Q: Are there any compliance or certification differences between these parts?

A: Both parts share identical ECCN (EAR99) and Moisture Sensitivity Level (MSL 1) classifications. The PS-20BD2-1 is RoHS Compliant, providing additional environmental compliance assurance.

Q: What inventory availability should I expect?

A: The ADIP 20Z-LC has 1,047 pieces in stock as new original inventory. The PS-20BD2-1 has 763 pieces in stock. Availability may vary by distributor and time of inquiry.
