Amphenol ICC 50294-1210EB Backplane Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 50294-1210EB is a 210-position high-density backplane connector designed for daughtercard applications. This receptacle features female sockets in a through-hole, right-angle configuration with a 0.100" (2.54mm) pitch across 3 rows and 70 columns. The connector is classified as obsolete, which necessitates identification of active equivalent parts to maintain design continuity and ensure ongoing component availability for production and field service applications.

Substitute Part Grouping Explanation

Substitution of the 50294-1210EB is determined by strict equivalence across the following parameters:

• Connector type and style (Receptacle, Female Sockets, High Density)
• Electrical configuration (210 positions, 3 rows × 70 columns)
• Mechanical interface (0.100" pitch, through-hole, right-angle mounting)
• Termination method (Solder)
• Contact specifications (Gold finish, 30.0µin thickness)
• Physical features (Board Lock, Mating Guide)
• Material compliance (UL94 V-0)

The substitute part 50294-1210EBLF maintains identical electrical and mechanical specifications while offering improved product status and regulatory compliance. Both parts share the same base product number (50294) and series designation (HPC™), confirming functional interchangeability within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

The 50294-1210EBLF is the direct substitute for the obsolete 50294-1210EB. Selection of the substitute part is justified on the following grounds:

• Product Status: The substitute part maintains active production status, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: The substitute part is RoHS Compliant, meeting current environmental and material restriction directives, whereas the main part is RoHS non-compliant.
• Functional Equivalence: All electrical, mechanical, and physical parameters remain identical, confirming pin-for-pin and form-factor compatibility.
• Certification Alignment: Both parts maintain UL94 V-0 material flammability rating and MSL 1 moisture sensitivity classification.

For new designs or component refresh cycles, the 50294-1210EBLF should be specified. For legacy systems currently using the 50294-1210EB, the substitute part provides a direct replacement path without design modification.

Frequently Asked Questions (FAQ)

Q: Are the 50294-1210EB and 50294-1210EBLF mechanically interchangeable?

A: Yes. Both parts share identical mounting type (through-hole, right-angle), pitch (0.100"), position count (210), and row/column configuration (3 × 70). They are form-factor compatible and require no PCB redesign.

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

A: The primary differences are product status and RoHS compliance. The 50294-1210EB is obsolete and RoHS non-compliant. The 50294-1210EBLF is active production and RoHS Compliant. All functional specifications are identical.

Q: Can I use the 50294-1210EBLF in place of the 50294-1210EB in existing designs?

A: Yes. The substitute part maintains all electrical and mechanical specifications. No circuit design changes or PCB layout modifications are required.

Q: What does the "LF" suffix in 50294-1210EBLF indicate?

A: The "LF" suffix typically indicates lead-free or RoHS-compliant material composition in Amphenol ICC part numbering conventions.

Q: Are there any differences in contact finish or plating between these parts?

A: No. Both parts specify gold contact finish at 30.0µin (0.76µm) thickness, ensuring equivalent electrical performance and mating characteristics.

Q: What is the moisture sensitivity level for both parts?

A: Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
