P50LE-100P1-SML-TGF Equivalent & Substitute Parts

Part Overview

The P50LE-100P1-SML-TGF is a rectangular connector header manufactured by 3M, designed for surface mount applications requiring 100-position, 1.27mm pitch interconnection. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and procurement planning. The substitute part P50LE-100P1-SML-DA provides direct functional equivalence with improved product status and compliance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P50LE-100P1-SML-TGF is determined by strict equivalence across the following critical parameters:

• Connector Type: Plug
• Number of Positions: 100
• Number of Rows: 2
• Pitch - Mating: 0.050" (1.27mm)
• Mounting Type: Surface Mount
• Termination: Solder
• Shrouding: Shrouded - 4 Wall
• Insulation Height: 0.197" (5.00mm)
• Contact Material: Phosphor Bronze
• Insulation Material: Polyphenylene Sulfide (PPS)
• Operating Temperature: -55°C ~ 85°C
• Current Rating: 0.5A
• Material Flammability Rating: UL94 V-0

The P50LE-100P1-SML-DA meets all these criteria and qualifies as a direct substitute. Variations in contact finish specifications and insulation material composition (glass-filled PPS) do not affect mechanical or electrical compatibility within the defined operating parameters.

Parameter Comparison

Engineering Selection Recommendations

The P50LE-100P1-SML-DA is the direct functional equivalent for the obsolete P50LE-100P1-SML-TGF. Selection of the substitute part is supported by:

• Identical mechanical and electrical specifications across all critical mating and mounting parameters
• Active product status ensuring continued availability and supply chain stability
• RoHS compliance of the substitute part, addressing regulatory requirements not met by the obsolete original
• Equivalent performance within the specified operating temperature range and current rating
• Maintained UL94 V-0 flammability certification

The contact finish variations (gold flash versus specified thickness on the original) and glass-filled insulation material composition of the substitute do not compromise functional compatibility within the defined electrical and mechanical operating envelope.

Frequently Asked Questions (FAQ)

Q: Can P50LE-100P1-SML-DA be used as a direct replacement for P50LE-100P1-SML-TGF in existing designs?

A: Yes. Both parts share identical connector type, position count, pitch, mounting method, and operating specifications. The substitute meets all mechanical and electrical requirements for direct substitution.

Q: What is the significance of the contact finish differences between the two parts?

A: The original part specifies tin post finish (80.0µin) and gold mating finish (2.00µin). The substitute uses gold flash finish for both mating and post contacts. Both finishes provide adequate electrical conductivity and corrosion resistance within the 0.5A current rating and operating temperature range.

Q: Does the glass-filled insulation material in the substitute part affect compatibility?

A: No. Glass-filled polyphenylene sulfide (PPS) maintains the same insulation height (0.197"), flammability rating (UL94 V-0), and mechanical properties as standard PPS. It does not affect mating or mounting characteristics.

Q: Why is RoHS compliance important for this substitution?

A: The original part is RoHS non-compliant, while the substitute is RoHS compliant. For new designs or systems subject to RoHS regulations, the substitute part ensures regulatory conformance without functional compromise.

Q: Are there packaging differences between the two parts?

A: The original part packaging is not specified. The substitute is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: What is the inventory status for each part?

A: The original P50LE-100P1-SML-TGF has 955 pieces in stock (obsolete status). The substitute P50LE-100P1-SML-DA has 1038 pieces in stock (active status), providing better long-term availability assurance.
