Substitute Part Grouping Explanation

Substitution eligibility for the P50L-100P-RR4-DA is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Plug with center strip contacts
• Electrical Interface: 100 positions at 0.050" (1.27mm) pitch, 2-row configuration
• Physical Form Factor: Through-hole, right-angle mounting with 0.354" (9.00mm) height above board
• Contact Material & Finish: Gold plating on contacts
• Mechanical Features: Board lock functionality
• Environmental Rating: MSL 1 (Unlimited moisture sensitivity)

The TX25-100P-LT-H1E from JAE Electronics meets all substitution criteria, maintaining identical position count, pitch, mounting orientation, and contact specifications. This part is currently in active production status with confirmed inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The TX25-100P-LT-H1E is the qualified substitute for the obsolete P50L-100P-RR4-DA based on the following factors:

Functional Equivalence: Both parts share identical connector architecture, position count, pitch spacing, and mounting configuration. The 100-position, 0.050" pitch specification with 2-row center strip contact design ensures mechanical and electrical interchangeability in existing PCB layouts.

Compliance Status: The TX25-100P-LT-H1E carries active ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for new designs and ongoing procurement. The original P50L-100P-RR4-DA does not specify these certifications.

Production Availability: The substitute part is in active production with confirmed inventory (2742 units), whereas the original part is obsolete with limited remaining stock (892 units). Selection of the active part ensures long-term supply chain continuity.

Contact Finish Specification: The substitute specifies a defined gold plating thickness of 4.00µin (0.100µm), compared to the original's flash finish. This provides consistent contact resistance and wear characteristics across production batches.

Frequently Asked Questions (FAQ)

Q: Can the TX25-100P-LT-H1E be used as a direct replacement in existing designs using the P50L-100P-RR4-DA?

A: Yes. Both parts maintain identical electrical and mechanical specifications: 100 positions, 0.050" pitch, 2-row configuration, through-hole right-angle mounting, and board lock features. PCB footprints and mating connector interfaces are compatible.

Q: What is the difference in gold plating between the two parts?

A: The original P50L-100P-RR4-DA specifies flash gold plating (thickness not defined). The TX25-100P-LT-H1E specifies 4.00µin (0.100µm) gold plating. Both finishes provide adequate contact conductivity and corrosion resistance for the application; the substitute's defined thickness ensures consistent batch-to-batch performance.

Q: Why is the original part listed as obsolete?

A: The P50L-100P-RR4-DA is classified as obsolete by the manufacturer, indicating it is no longer in active production. The TX25-100P-LT-H1E from JAE Electronics is the current active equivalent in the market.

Q: Are there packaging differences between these parts?

A: The original part packaging is not specified in available data. The substitute is supplied in tray packaging. Confirm packaging requirements with your procurement process.

Q: Does the substitute meet current regulatory standards?

A: Yes. The TX25-100P-LT-H1E is ROHS3 compliant and REACH unaffected, meeting current environmental and chemical restriction requirements. The original part's compliance status is not specified.

Q: What is the MSL rating for both parts?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
