Key Parameters

Substitute Part Grouping Explanation

Substitution of the 50003-1172E is determined by strict equivalence across the following critical parameters:

• Connector type and style (Receptacle, Female Sockets; High Density)
• Number of positions and configuration (172 positions; 4 rows × 43 columns)
• Pitch specification (0.100" / 2.54mm)
• Mounting type and orientation (Through Hole, Right Angle)
• Termination method (Solder)
• Contact finish specification (Gold plating)
• Series compatibility (HPC™)

The substitute part 50003-1172ELF maintains identical electrical and mechanical specifications to the original part. The primary distinction is product status and RoHS compliance, which may be relevant depending on application requirements and regulatory context.

Parameter Comparison

Engineering Selection Recommendations

The 50003-1172ELF is a direct functional equivalent to the 50003-1172E. Both parts share identical electrical and mechanical specifications, including connector type, position count, pitch, mounting configuration, and contact finish.

The 50003-1172ELF is currently in active production status, whereas the 50003-1172E is obsolete. For new designs or ongoing production requiring this connector specification, the 50003-1172ELF is the appropriate selection.

The 50003-1172ELF carries RoHS compliance certification, whereas the 50003-1172E does not. Applications subject to RoHS regulatory requirements should specify the 50003-1172ELF.

Frequently Asked Questions (FAQ)

Q: Can the 50003-1172ELF be used as a direct replacement for the 50003-1172E?

A: Yes. Both parts are identical in electrical and mechanical specifications. The 50003-1172ELF is the active production equivalent of the obsolete 50003-1172E.

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

A: The primary differences are product status and RoHS compliance. The 50003-1172E is obsolete and RoHS non-compliant. The 50003-1172ELF is in active production and RoHS compliant. All connector specifications remain identical.

Q: Are there any compatibility concerns when substituting the 50003-1172ELF for the 50003-1172E?

A: No. Both parts maintain the same 172-position configuration, 0.100" pitch, through-hole right-angle mounting, and gold contact finish. PCB footprints and mating interfaces are identical.

Q: Does the RoHS compliance status affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical or mechanical performance. Both parts deliver equivalent functionality.

Q: What is the MSL rating for these connectors?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
