Substitute Part Grouping Explanation

Substitution eligibility for the 50003-1200F is determined by strict equivalence across the following parameters:

• Connector Type & Style: Must be Receptacle, Female Sockets in High Density (HDC, HDI, HPC) configuration
• Position Count & Layout: Must maintain 200 positions in 4 rows × 50 columns
• Pitch & Spacing: Must match 0.100" (2.54mm) pitch
• Mounting & Termination: Must be Through Hole, Right Angle with Solder termination
• Contact Specifications: Must feature gold plating at 30.0µin (0.76µm) thickness
• Series Compatibility: Must belong to the HPC™ series with base product number 50003

The 50003-1200FLF meets all substitution criteria as a direct equivalent within the same product family.

Parameter Comparison

Engineering Selection Recommendations

The 50003-1200FLF is the direct functional equivalent of the 50003-1200F. Both components share identical electrical and mechanical specifications across all critical parameters: connector type, position count, pitch, mounting configuration, and contact finish.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The 50003-1200F is classified as obsolete, while the 50003-1200FLF maintains active product status. Additionally, the 50003-1200FLF carries RoHS Compliant certification, whereas the 50003-1200F is RoHS non-compliant.

For new designs and ongoing system support where component availability is a consideration, the 50003-1200FLF is the appropriate selection. Both parts are functionally interchangeable in applications where the mechanical and electrical interface requirements are identical.

Frequently Asked Questions (FAQ)

Q: Are the 50003-1200F and 50003-1200FLF mechanically interchangeable?

A: Yes. Both connectors share identical mounting type (through hole, right angle), PCB footprint dimensions (4 rows × 50 columns at 0.100" pitch), and contact configuration. They are mechanically interchangeable in PCB designs.

Q: What is the significance of the "FLF" suffix in the 50003-1200FLF part number?

A: The "FLF" suffix indicates RoHS Compliant status and active product lifecycle. The base 50003-1200F lacks this designation and is RoHS non-compliant.

Q: Can I use the 50003-1200FLF as a direct replacement for the 50003-1200F in existing assemblies?

A: Yes. The 50003-1200FLF is a direct substitute. All electrical and mechanical parameters are identical, ensuring functional compatibility in existing designs.

Q: Are there any differences in contact finish or plating specifications?

A: No. Both parts feature gold-plated contacts with identical thickness specification of 30.0µin (0.76µm).

Q: What is the current availability status of these parts?

A: The 50003-1200F is obsolete with 1101 pieces in stock. The 50003-1200FLF is active with 915 pieces in stock.
