Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 2-1589474-1 connector is based on 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
• Termination: Wire Leads
• Contact Finish: Gold
• Wire Gauge: 30 AWG
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part SSL025PC2DC006 satisfies all mandatory parameters required for functional and mechanical compatibility. While the substitute exhibits differences in row configuration (1 row versus 2 rows in the original) and additional specifications such as dielectric material and contact material composition, these variations do not preclude substitution when the connector layout and pin count remain functionally equivalent for the application.

Parameter Comparison

Engineering Selection Recommendations

The SSL025PC2DC006 connector is the designated substitute for the obsolete 2-1589474-1 part. Selection of this substitute is supported by the following factors:

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

Compliance and Certifications: The SSL025PC2DC006 achieves ROHS3 compliance, providing enhanced environmental and regulatory alignment for new designs and production batches. Both parts carry identical ECCN classification (EAR99), maintaining export control consistency.

Electrical and Mechanical Compatibility: The substitute maintains all critical connector parameters including 25-position configuration, D-Type Nano-D style, male pin plug type, free hanging in-line mounting, gold contact finish, and 30 AWG wire gauge termination. These parameters ensure direct functional compatibility in existing applications.

Moisture Sensitivity: Both parts share MSL 1 (Unlimited) classification, indicating equivalent moisture handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can SSL025PC2DC006 directly replace 2-1589474-1 in existing applications?

A: Yes. Both connectors maintain identical specifications for connector style (D-Type, Nano-D), connector type (Plug, Male Pins), position count (25), mounting configuration (Free Hanging In-Line), contact type (Signal), termination method (Wire Leads), contact finish (Gold), and wire gauge (30 AWG). These parameters define functional and mechanical compatibility.

Q: What is the significance of the row configuration difference (2 rows versus 1 row)?

A: The row configuration difference reflects the internal pin arrangement within the 25-position connector. The substitute part SSL025PC2DC006 uses a single-row configuration while the original uses a two-row configuration. This difference does not affect substitution compatibility when the overall connector layout and pin count remain functionally equivalent for the application.

Q: Does the substitute part have better compliance status?

A: The SSL025PC2DC006 achieves ROHS3 compliance, whereas the original part does not specify RoHS status. Both parts maintain identical ECCN classification (EAR99) and equivalent moisture sensitivity levels (MSL 1, Unlimited). The substitute's active production status provides superior long-term availability compared to the obsolete original.

Q: Are there differences in contact material composition?

A: The substitute part specifies Beryllium Copper contact material and Liquid Crystal Polymer (LCP) dielectric material, with a defined contact finish thickness of 30.0µin (0.76µm). The original part does not provide these material specifications. Both parts maintain gold contact finish and are functionally compatible for signal applications.

Q: What is the inventory status for each part?

A: The original 2-1589474-1 has 851 pieces in stock with obsolete status. The substitute SSL025PC2DC006 has 1099 pieces in stock with active product status, providing greater availability and ongoing supply assurance.
