Parameter Comparison

Engineering Selection Recommendations

The 50003-1216HLF is the direct active equivalent for the obsolete 50003-1216H. Selection of the substitute part is based on the following engineering criteria:

Product Status: The original part is classified as obsolete, while the substitute maintains active product status with ongoing manufacturer support and availability.

Regulatory Compliance: The 50003-1216HLF achieves RoHS compliance, whereas the original part is RoHS non-compliant. This distinction is significant for applications subject to RoHS directives and environmental regulations.

Electrical & Mechanical Equivalence: All functional parameters—position count, pitch, mounting configuration, termination method, and contact specifications—are identical between the two parts, ensuring direct PCB-level compatibility.

Supply Chain Continuity: With 783 units in current inventory, the substitute part provides reliable supply availability compared to the obsolete original.

Frequently Asked Questions (FAQ)

Q: Can the 50003-1216HLF be used as a direct replacement for the 50003-1216H in existing designs?

A: Yes. The substitute part maintains identical electrical and mechanical specifications across all critical parameters: 216-position configuration, 0.100" pitch, through-hole right-angle mounting, solder termination, and gold contact finish. PCB layouts and mating connector specifications require no modification.

Q: What is the significance of the RoHS compliance difference?

A: The 50003-1216HLF is RoHS compliant, meeting Restriction of Hazardous Substances directives. The original 50003-1216H is non-compliant. For applications subject to RoHS regulations or customer requirements, the substitute part is the appropriate selection.

Q: Are there any packaging or handling differences between these parts?

A: Both parts share identical moisture sensitivity level (MSL 1 - Unlimited), indicating no special moisture control requirements during storage or handling. Packaging specifications are not differentiated in the provided data.

Q: How do I verify compatibility with existing mating connectors?

A: Compatibility is determined by the HPC™ series designation, 216-position count, 0.100" pitch specification, and right-angle through-hole mounting configuration. Verify that mating connectors reference the same series and position count. The mating guide feature is present on both parts.

Q: What is the difference between the part numbers 50003-1216H and 50003-1216HLF?

A: The suffix "LF" in 50003-1216HLF indicates lead-free construction, which correlates with RoHS compliance. The base product number 50003 and all functional specifications remain identical.
