Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 2-1589474-2 connector is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: D-Type, Nano-D
• Connector Type: Plug, Male Pins
• Number of Positions: 25
• Mounting Type: Free Hanging (In-Line)
• Contact Type: Signal
• Flange Feature: Mating Side, Female Screwlock
• Termination: Wire Leads
• Contact Finish: Gold
• Wire Gauge: 30 AWG

The substitute part SSL025PC2DC006N meets all mandatory electrical and mechanical compatibility criteria. While the substitute exhibits a single-row configuration (versus the two-row layout of the main part), both components maintain the 25-position contact count and identical termination, flange, and contact specifications required for functional equivalence in wire lead applications.

Parameter Comparison

Engineering Selection Recommendations

The SSL025PC2DC006N connector is the designated substitute for the obsolete 2-1589474-2 based on the following engineering criteria:

Product Status Alignment: The substitute part maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Electrical and Mechanical Compatibility: Both connectors share identical specifications for connector style, type, position count, mounting configuration, contact type, flange design, termination method, contact finish, and wire gauge. These parameters establish functional equivalence for signal transmission and mechanical mating.

Regulatory Compliance: The substitute part carries ROHS3 compliance certification, providing enhanced environmental and regulatory standing. Both parts share identical ECCN (EAR99) and HTSUS (8544.42.9090) classifications, maintaining consistent export and tariff treatment.

Moisture Sensitivity: Both parts maintain MSL 1 (Unlimited) rating, indicating identical moisture handling requirements and storage conditions.

Material Specifications: The substitute incorporates Liquid Crystal Polymer (LCP) dielectric material and Beryllium Copper contacts with specified gold finish thickness (30.0µin), providing documented material composition for traceability and performance assurance.

Frequently Asked Questions (FAQ)

Q: Can SSL025PC2DC006N directly replace 2-1589474-2 in existing applications?

A: Yes. Both connectors maintain identical specifications for the 25 signal positions, male pin configuration, wire lead termination, gold contact finish, 30 AWG wire gauge, and mating side female screwlock flange. The single-row versus two-row layout difference does not affect electrical or mechanical compatibility for wire lead applications.

Q: What is the primary reason for substitution?

A: The 2-1589474-2 is classified as obsolete. The SSL025PC2DC006N is an active production part from the same manufacturer, ensuring continued availability for repair, maintenance, and new production requirements.

Q: Are there differences in contact material between the two parts?

A: The main part does not specify contact material composition. The substitute part uses Beryllium Copper contacts with documented gold finish thickness of 30.0µin (0.76µm), providing specified material traceability.

Q: Do both connectors have the same moisture sensitivity requirements?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating identical moisture sensitivity levels and storage condition requirements.

Q: What is the difference in row configuration?

A: The main part features a 2-row layout while the substitute features a 1-row layout. Both maintain 25 total positions. For wire lead termination applications, this configuration difference does not impact electrical performance or mechanical mating compatibility.

Q: Are there regulatory compliance differences?

A: The substitute part carries ROHS3 compliance certification, whereas the main part does not specify RoHS status. Both parts share identical ECCN (EAR99) and HTSUS (8544.42.9090) classifications. The substitute's REACH status is vendor-undefined, while the main part is REACH Unaffected.

Q: What is the inventory status of the substitute part?

A: SSL025PC2DC006N has 1104 pieces in new original stock, providing immediate availability for procurement.
