Substitute Part Grouping Explanation

The P50L-040P-AS-TGF has one identified equivalent substitute: P50L-040P-AS-DA. This substitution is valid based on the following critical parameters that remain constant across both parts:

• Connector type and contact configuration (Plug, Center Strip Contacts)
• Position count and electrical interface (40 positions)
• Pitch specification (0.050" / 1.27mm)
• Row configuration (2 rows)
• Mounting technology (Surface Mount)
• Physical envelope (Height Above Board: 0.197", Mated Stacking Heights: 7mm, 8mm)
• Mechanical features (Board Guide, Solder Retention)
• Moisture sensitivity rating (MSL 1)

These parameters define the functional and mechanical compatibility required for direct substitution in applications originally designed for the P50L-040P-AS-TGF.

Engineering Selection Recommendations

The P50L-040P-AS-DA is the direct functional equivalent for the obsolete P50L-040P-AS-TGF. Selection of the substitute part is based on the following engineering criteria:

Product Status: The P50L-040P-AS-DA maintains active production status, ensuring continued availability and supply chain reliability compared to the obsolete main part.

Regulatory Compliance: The P50L-040P-AS-DA achieves ROHS3 compliance, addressing modern regulatory requirements for electronic components. The original part is RoHS non-compliant, making the substitute necessary for applications subject to RoHS directives.

Electrical and Mechanical Compatibility: Both parts maintain identical specifications across all critical parameters including position count, pitch, mounting type, and physical dimensions, ensuring direct interchangeability in existing designs without circuit modification or PCB redesign.

Contact Finish Specification: The substitute part specifies flash gold plating versus the 2.00µin thickness of the original. Flash plating is standard for this connector series and provides adequate contact performance for the intended application class.

Frequently Asked Questions (FAQ)

Q: Can P50L-040P-AS-DA be used as a direct replacement for P50L-040P-AS-TGF in existing designs?

A: Yes. Both parts share identical connector type, position count, pitch, row configuration, mounting type, and physical envelope. No circuit redesign or PCB modification is required.

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

A: The original part specifies 2.00µin (0.051µm) gold thickness, while the substitute uses flash gold plating. Flash plating is the standard specification for this connector series and provides equivalent contact performance for the application.

Q: Why is the substitute part listed as active while the original is obsolete?

A: The P50L-040P-AS-DA represents the current production variant within the P50L series. The original part number has been discontinued, making the substitute the available alternative for new procurement and production requirements.

Q: Does the substitute part meet RoHS requirements?

A: Yes. The P50L-040P-AS-DA is ROHS3 compliant. The original part is RoHS non-compliant. For applications subject to RoHS directives, the substitute is the required selection.

Q: Are the packaging formats interchangeable?

A: The substitute is supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility. Verify packaging requirements for your specific procurement and assembly processes.

Q: What are the moisture sensitivity requirements for both parts?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard handling procedures apply to both variants.
