P25E-050S-TG Equivalent & Substitute Parts

Part Overview

The P25E-050S-TG is a 50-position rectangular receptacle connector manufactured by 3M, designed for IDC (Insulation Displacement Contact) termination with ribbon cable at 30 AWG wire gauge. This connector features gold-plated contacts and is configured as a feed-through receptacle with latch lock/eject hook fastening. The part is currently obsolete, making identification of compatible substitute components essential for ongoing system support and maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P25E-050S-TG is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle) and contact type (Female Socket)
• Position count (50) and pitch spacing (0.050"/1.27mm)
• Row configuration (2 rows)
• Termination method (IDC) and wire gauge compatibility (30 AWG)
• Mounting style (Free Hanging In-Line) and fastening mechanism (Latch Lock/Eject Hooks)
• Contact finish specification (Gold)
• Feed-through functionality

The P25E-050S-EA qualifies as a direct substitute because it maintains identical electrical and mechanical specifications across all these parameters. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The P25E-050S-EA is the direct functional equivalent of the P25E-050S-TG. Both parts share identical electrical and mechanical specifications, ensuring pin-for-pin and form-factor compatibility in existing applications.

Selection between these parts should be based on regulatory and compliance requirements:

• For applications requiring ROHS3 compliance, the P25E-050S-EA is the appropriate selection.
• The P25E-050S-TG, while obsolete, remains available in inventory (643 units) and may be suitable for legacy system maintenance where RoHS compliance is not mandated.
• The P25E-050S-EA is currently in active production status with higher inventory availability (1353 units), providing supply chain continuity for new designs and ongoing production.

Frequently Asked Questions (FAQ)

Q: Are P25E-050S-TG and P25E-050S-EA mechanically interchangeable?

A: Yes. Both connectors are identical in form factor, mounting configuration, and fastening mechanism. They can be used interchangeably in applications where the connector interfaces with 50-position IDC ribbon cables at 30 AWG.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and compliance certification. The P25E-050S-TG is obsolete and RoHS non-compliant, while the P25E-050S-EA is active production and ROHS3 compliant. All electrical and mechanical specifications are identical.

Q: Can I use P25E-050S-EA as a replacement for P25E-050S-TG in existing designs?

A: Yes. The P25E-050S-EA is a direct substitute with no design modifications required. It maintains all electrical and mechanical compatibility.

Q: What does "Feed Through" mean for this connector?

A: Feed-through indicates that the connector allows signal or power to pass through the connector body, enabling daisy-chaining or pass-through configurations in ribbon cable applications.

Q: Are there any packaging differences between these parts?

A: The P25E-050S-TG packaging is not specified in available data. The P25E-050S-EA is supplied in bulk packaging.

Q: What is the contact finish thickness difference?

A: The P25E-050S-TG specifies 10.0µin (0.25µm) gold plating thickness. The P25E-050S-EA specifies flash gold plating. Both provide adequate contact durability for IDC termination applications.
