Key Parameters

Substitute Part Grouping Explanation

Substitution of the 50003-1240H is determined by strict equivalence across the following parameters:

• Connector type and gender (Receptacle, Female Sockets)
• Position count (240 positions)
• Pitch specification (0.100" / 2.54mm)
• Physical configuration (4 rows, 60 columns)
• Mounting method (Through Hole, Right Angle)
• Termination type (Solder)
• Contact finish specification (Gold plating)
• High-density connector style classification

The 50003-1240HLF meets all these criteria and is manufactured by the same supplier within the same HPC™ series, ensuring mechanical and electrical compatibility with applications designed for the 50003-1240H.

Parameter Comparison

Engineering Selection Recommendations

The 50003-1240HLF is the direct substitute for the obsolete 50003-1240H. Both parts share identical mechanical and electrical specifications within the HPC™ series. The primary distinction is product status and regulatory compliance: the 50003-1240HLF is currently in active production and meets RoHS compliance requirements, whereas the 50003-1240H is obsolete and RoHS non-compliant.

For new designs and systems requiring 240-position high-density backplane connectors with 0.100" pitch and right-angle through-hole mounting, the 50003-1240HLF is the appropriate selection. For legacy system maintenance where the original 50003-1240H is specified, the 50003-1240HLF provides direct functional equivalence with the added benefit of current availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Are the 50003-1240H and 50003-1240HLF mechanically interchangeable?

A: Yes. Both connectors share identical physical dimensions, mounting configuration (through-hole, right-angle), and contact pitch (0.100" / 2.54mm). They are mechanically interchangeable in PCB layouts designed for either part.

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

A: The primary differences are product lifecycle status and regulatory compliance. The 50003-1240H is obsolete and RoHS non-compliant. The 50003-1240HLF is in active production and RoHS compliant. All electrical and mechanical parameters are identical.

Q: Can I use the 50003-1240HLF as a direct replacement in existing assemblies?

A: Yes. The 50003-1240HLF is a direct substitute for the 50003-1240H. No design modifications or PCB layout changes are required.

Q: Are there any electrical performance differences between these connectors?

A: No. Both parts have identical contact finish (gold, 30.0µin), termination method (solder), and connector style (high-density). Electrical performance is equivalent.

Q: Why should I transition from the 50003-1240H to the 50003-1240HLF?

A: The 50003-1240H is obsolete and subject to supply discontinuation. The 50003-1240HLF is actively manufactured, ensuring long-term availability. Additionally, RoHS compliance of the 50003-1240HLF meets current regulatory requirements for many markets and applications.

Q: What is the MSL rating for these connectors?

A: Both the 50003-1240H and 50003-1240HLF have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
