Overview

The nVent SCHROFF 21500072 is a CompactPCI subrack designed for railway applications, specifically complying with SNCF standards. It features a 6U height and supports 36 HP (Half-Height) slots within a 320 mm depth chassis. The unit is constructed from aluminum and includes shielding capabilities to ensure electromagnetic compatibility in demanding transport environments.

Feature Summary

• Compliant with SNCF specifications for railway electronics packaging
• Shielded design for CompactPCI bus applications
• Aluminum construction for structural integrity and thermal management

Applications

• SNCF compliant railway control systems
• CompactPCI based train monitoring equipment
• Railway signaling and communication hardware enclosures

Procurement Notes

Verify the specific revision of the SNCF standard required for your deployment, as railway certifications can vary by region and era. Confirm that the 320 mm depth aligns with your cabinet constraints. Ensure the shielded variant matches your EMI requirements. Cross-reference the part number with official nVent SCHROFF documentation to confirm current production status and any superseding models.

Selection Notes

Select this model only if SNCF railway compliance is mandatory for your project. The 6U form factor limits vertical expansion compared to larger racks. Verify that the 36 HP slot count meets your board density needs. Consider the 320 mm depth limitation when integrating with deep backplanes or peripheral modules. Aluminum material selection offers weight savings over steel but may require additional coating for harsh corrosion environments.

Part Context

This component belongs to the nVent SCHROFF subrack family, specialized for industrial and transport sectors. It serves as a mechanical housing for CompactPCI modules. The product line emphasizes ruggedness and adherence to specific regional transport regulations, such as those set by French National Railway Company (SNCF).

Replacement Considerations

Check nVent SCHROFF catalogs for updated part numbers, as railway components often undergo revision cycles. Generic 6U CompactPCI subracks may not meet SNCF certification requirements. Verify mechanical mounting hole patterns and electrical grounding points before substituting with non-OEM alternatives.
