Key Parameters

Substitute Part Grouping Explanation

Substitution of the P50L-040S-BS-TGF is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Socket with outer shroud contacts, 40 positions, 2-row arrangement
• Electrical Interface: 0.050" (1.27mm) pitch
• Mounting Technology: Surface mount with board guide and solder retention features
• Contact Properties: Gold finish for electrical performance and corrosion resistance
• Physical Envelope: Height above board of 0.252" (6.40mm) and mated stacking heights of 7mm and 8mm
• Series Compatibility: Pak 50 and P50L series designation

The substitute part P50L-040S-BS-DA meets all these critical parameters and maintains full mechanical and electrical compatibility with the original part.

Parameter Comparison

Engineering Selection Recommendations

The P50L-040S-BS-DA is the direct substitute for the obsolete P50L-040S-BS-TGF. Both parts maintain identical mechanical and electrical specifications across all critical parameters including connector configuration, pitch, mounting type, and physical dimensions.

The primary distinction between the two parts is product status and regulatory compliance. The P50L-040S-BS-TGF is obsolete and RoHS non-compliant, while the P50L-040S-BS-DA is active and ROHS3 compliant. The contact finish thickness differs (2.00µin versus flash), but both maintain gold plating for equivalent electrical performance.

For new designs or ongoing production requiring this connector type, the P50L-040S-BS-DA is the appropriate selection due to its active status and regulatory compliance. For legacy system support where the original part specification must be maintained, the P50L-040S-BS-DA provides full functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can P50L-040S-BS-DA be used as a direct replacement for P50L-040S-BS-TGF?

A: Yes. Both parts are identical in connector type, position count, pitch, mounting configuration, and physical dimensions. The P50L-040S-BS-DA is the active equivalent and is fully compatible.

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

A: The P50L-040S-BS-TGF specifies 2.00µin (0.051µm) gold plating, while the P50L-040S-BS-DA uses flash gold plating. Both provide gold contact finish for electrical performance and corrosion resistance. Flash plating is a thinner application suitable for surface mount connectors.

Q: Why is the original part obsolete?

A: The P50L-040S-BS-TGF is classified as obsolete. The P50L-040S-BS-DA represents the current active offering from 3M for this connector configuration and is the recommended source for procurement.

Q: Are there packaging differences between these parts?

A: The P50L-040S-BS-TGF packaging is listed as unspecified, while the P50L-040S-BS-DA is supplied in bulk packaging. Both parts are identical in form, fit, and function.

Q: What is the RoHS compliance status?

A: The P50L-040S-BS-TGF is RoHS non-compliant. The P50L-040S-BS-DA is ROHS3 compliant, making it suitable for applications requiring regulatory compliance with current environmental standards.

Q: Are the moisture sensitivity levels the same?

A: Yes. Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
