Key Parameters

Substitute Part Grouping Explanation

Substitution of the P50L-040P-RR4-DA is determined by strict equivalence across the following critical parameters:

• Connector Type: Plug with center strip contacts
• Position Count: 40 positions
• Pitch Specification: 0.050" (1.27mm)
• Row Configuration: 2 rows
• Mounting Method: Through hole, right angle orientation
• Contact Material: Gold plating
• Board Height: 0.354" (9.00mm)

The TX25-40P-LT-N1E from JAE Electronics meets all these requirements and is classified as an active product, providing continuity for applications currently using the obsolete P50L-040P-RR4-DA.

Parameter Comparison

Engineering Selection Recommendations

The TX25-40P-LT-N1E is the direct substitute for the P50L-040P-RR4-DA. Selection is based on:

• Electrical Compatibility: Identical position count, pitch, and contact configuration ensure direct functional equivalence
• Mechanical Compatibility: Matching mounting type, orientation, and board height enable direct PCB integration without redesign
• Product Lifecycle: The TX25-40P-LT-N1E is an active product with current manufacturing support, addressing the obsolescence of the original part
• Compliance: The substitute meets ROHS3 requirements, supporting modern regulatory standards

Frequently Asked Questions (FAQ)

Q: Can the TX25-40P-LT-N1E be used as a direct replacement for the P50L-040P-RR4-DA?

A: Yes. Both connectors share identical electrical and mechanical specifications: 40 positions, 0.050" pitch, 2-row configuration, through-hole right-angle mounting, and gold contact finish. The board height of 0.354" is identical, permitting direct PCB substitution.

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

A: The P50L-040P-RR4-DA specifies flash gold plating, while the TX25-40P-LT-N1E specifies 4.00µin (0.100µm) gold plating. Both finishes provide equivalent corrosion resistance and electrical performance for standard applications.

Q: Does the packaging difference affect compatibility?

A: Packaging format (bulk versus tray) does not affect electrical or mechanical compatibility. The TX25-40P-LT-N1E is supplied in tray packaging, which is standard for active production parts and does not impact connector performance or PCB integration.

Q: Is the TX25-40P-LT-N1E suitable for applications requiring ROHS compliance?

A: Yes. The TX25-40P-LT-N1E is ROHS3 compliant, meeting current environmental and regulatory requirements. The original P50L-040P-RR4-DA does not specify RoHS status.

Q: Are there any electrical performance differences between these connectors?

A: No. Both connectors maintain identical electrical specifications across all provided parameters: contact material, finish, pitch, and position count. Electrical performance is equivalent.
