Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 50003-1252E is determined by strict equivalence across the following critical parameters:

• Connector type and style (Receptacle, Female Sockets; High Density)
• Position count and array configuration (252 positions, 4 rows × 63 columns)
• Pitch specification (0.100" / 2.54mm)
• Mounting method (Through Hole, Right Angle)
• Termination type (Solder)
• Contact material and finish (Gold, 30.0µin thickness)
• Mating guide feature presence

The 50003-1252ELF meets all these criteria and is classified as a direct substitute. The primary distinction between the main part and its substitute is product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The 50003-1252ELF is the direct functional equivalent of the 50003-1252E. Selection between these parts is determined by regulatory and supply chain requirements rather than electrical or mechanical performance differences.

For new designs and systems requiring RoHS compliance, the 50003-1252ELF is the appropriate selection. This part maintains active product status with Amphenol ICC (FCI), ensuring ongoing availability and supply chain support.

For legacy system maintenance where RoHS compliance is not mandated, either part is functionally equivalent. However, the 50003-1252ELF is preferred due to its active status and superior long-term availability. The 50003-1252E remains available in current inventory (892 pcs) for immediate requirements in non-RoHS applications.

Frequently Asked Questions (FAQ)

Q: Can the 50003-1252ELF be used as a direct replacement for the 50003-1252E?

A: Yes. Both parts are identical in electrical and mechanical specifications, including connector type, position count, pitch, mounting method, and contact finish. The 50003-1252ELF is the active equivalent with RoHS compliance.

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

A: The primary differences are product status and regulatory compliance. The 50003-1252E is obsolete and RoHS non-compliant. The 50003-1252ELF is active and RoHS compliant. All functional parameters are identical.

Q: Are there any compatibility concerns when substituting one part for the other?

A: No compatibility concerns exist. Both parts share identical connector geometry, pin configuration, pitch, and mounting specifications. They are fully interchangeable at the board level.

Q: Which part should be selected for new designs?

A: The 50003-1252ELF should be selected for new designs. It is the active product with RoHS compliance and ensures long-term supply chain availability.

Q: Is the 50003-1252E still available?

A: The 50003-1252E is currently available in inventory (892 pcs new original stock) but is classified as obsolete. Future availability is not guaranteed.
