Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 50003-1140F is determined by strict equivalence across the following critical parameters:

• Connector type: Receptacle with female sockets
• Connector style: High density (HPC series)
• Number of positions: 140 (all positions loaded)
• Pitch: 0.100" (2.54mm)
• Row and column configuration: 4 rows × 35 columns
• Mounting type: Through hole, right angle
• Termination method: Solder
• Contact finish: Gold plating
• Mating guide feature: Present

The substitute part 50003-1140FLF maintains identical electrical and mechanical specifications across all these parameters. The primary distinction is product status: the substitute transitions from obsolete to active production status, and includes RoHS compliance certification, making it suitable for new designs and ongoing procurement.

Parameter Comparison

Engineering Selection Recommendations

The 50003-1140FLF is the direct active equivalent for the obsolete 50003-1140F. Both parts share identical mechanical and electrical specifications, ensuring pin-for-pin and footprint compatibility. The substitute part offers two significant advantages: active production status ensures long-term availability and supply chain stability, and RoHS compliance certification aligns with current regulatory requirements for electronic components in most markets.

For applications requiring RoHS non-compliant components, the original 50003-1140F remains available through existing inventory channels. However, for new designs and ongoing production, the 50003-1140FLF is the recommended selection based on product lifecycle and compliance status.

Frequently Asked Questions (FAQ)

Q: Are the 50003-1140F and 50003-1140FLF mechanically interchangeable?

A: Yes. Both parts feature identical connector geometry, pitch, mounting configuration, and contact layout. They are direct mechanical substitutes with no PCB redesign required.

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

A: The primary differences are product status and RoHS compliance. The 50003-1140FLF is an active production part with RoHS certification, while the 50003-1140F is obsolete and RoHS non-compliant. All electrical and mechanical specifications are identical.

Q: Can I use the 50003-1140FLF as a replacement in existing designs using the 50003-1140F?

A: Yes. The substitute part maintains full compatibility with existing PCB layouts, mating connectors, and system designs. No modifications are required.

Q: What does the "FLF" suffix in 50003-1140FLF indicate?

A: The suffix denotes manufacturing and compliance variations within the HPC™ series. The FLF variant specifically indicates the RoHS-compliant version of the base 50003-1140 connector.

Q: Is the contact finish identical between both parts?

A: Yes. Both parts feature gold plating at 30.0µin (0.76µm) thickness, ensuring equivalent electrical performance and mating characteristics.

Q: What is the significance of the MSL rating for these connectors?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors can be stored and handled without special humidity controls or baking requirements prior to assembly.
