P50LE-050P1-SML-TGF Equivalent & Substitute Parts

Part Overview

The P50LE-050P1-SML-TGF is a rectangular connector header manufactured by 3M, designed for surface mount applications with 50 positions at 0.050" (1.27mm) pitch. This connector features a shrouded 4-wall design with solder termination and is classified as obsolete. Due to its obsolete status, identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications.

Substitute Part Grouping Explanation

Substitution eligibility for the P50LE-050P1-SML-TGF is determined by strict adherence to the following critical parameters:

• Connector Type & Series: Must be Plug type from the P50LE series
• Position Count & Row Configuration: Must maintain 50 positions in 2 rows
• Pitch Specification: Must match 0.050" (1.27mm) mating pitch
• Mounting Technology: Must be Surface Mount
• Shrouding Design: Must be Shrouded - 4 Wall configuration
• Termination Method: Must use Solder termination
• Insulation Material: Must be Polyphenylene Sulfide (PPS) or PPS Glass Filled
• Operating Temperature Range: Must support -55°C ~ 85°C
• Current Rating: Must support 0.5A minimum
• Flammability Compliance: Must meet UL94 V-0 rating

The substitute part P50LE-050P1-SML-DA meets all these critical parameters and is therefore electrically and mechanically compatible with the main part.

Engineering Selection Recommendations

The P50LE-050P1-SML-DA is a direct substitute for the P50LE-050P1-SML-TGF based on electrical and mechanical compatibility. The substitute part offers the following advantages:

• Active Product Status: The substitute is currently in active production, ensuring long-term availability and supply chain stability compared to the obsolete main part.
• RoHS Compliance: The substitute meets RoHS compliance requirements, whereas the main part is RoHS non-compliant. This is significant for applications subject to environmental regulations.
• Enhanced Insulation Material: The substitute uses glass-filled PPS insulation, providing improved mechanical and thermal properties while maintaining the same operating temperature range.
• Contact Finish Upgrade: The substitute features gold plating on both mating and post contacts, compared to tin plating on the post contacts of the main part. This provides enhanced corrosion resistance and contact reliability.

For new designs or component replacement in existing applications, the P50LE-050P1-SML-DA is the recommended selection.

Frequently Asked Questions (FAQ)

Q: Are P50LE-050P1-SML-TGF and P50LE-050P1-SML-DA mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications: 50 positions, 2 rows, 0.050" (1.27mm) pitch, shrouded 4-wall design, and surface mount configuration. They are pin-compatible and footprint-compatible.

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

A: The main part (P50LE-050P1-SML-TGF) has gold-plated mating contacts and tin-plated post contacts. The substitute (P50LE-050P1-SML-DA) has gold plating on both mating and post contacts. Gold plating provides superior corrosion resistance and contact reliability.

Q: Does the glass-filled PPS insulation in the substitute part affect electrical performance?

A: No. Glass-filled PPS maintains the same electrical properties as standard PPS while providing improved mechanical strength and thermal stability. Both materials meet UL94 V-0 flammability requirements and support the same operating temperature range of -55°C to 85°C.

Q: Why is the main part obsolete?

A: The P50LE-050P1-SML-TGF is classified as obsolete by the manufacturer. The P50LE-050P1-SML-DA represents the current active production equivalent within the same series.

Q: Is RoHS compliance a functional requirement for substitution?

A: RoHS compliance is a regulatory and environmental requirement, not a functional electrical or mechanical requirement. However, for applications subject to RoHS regulations or customer specifications, the substitute part's RoHS compliance is a significant advantage.

Q: What is the current rating for both parts?

A: Both the main part and substitute are rated for 0.5A per contact. This current rating applies to the connector contacts and must be considered in circuit design.

Q: Are there any packaging differences between these parts?

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