GPU Parts Cross-Reference: Hobart, Tronair, and TLD Interchangeable Components
Parts Engineering Team·May 1, 2026
Why Cross-Reference Matters
Running a multi-brand GSE fleet means managing diverse parts inventories. Some components — especially standard electrical and hydraulic parts — are interchangeable across brands.
Direct Cross-References
Cooling Fans
| Description | Hobart P/N | Tronair P/N | TLD P/N | Common (Nidec/Multifan) |
| 24" Axial Fan, 460V | H-FAN-2400 | T-FAN-24 | 24-FAN-460 | MF-24-460-3P |
| 18" Axial Fan, 230V | H-FAN-1800 | T-FAN-18 | 18-FAN-230 | MF-18-230-1P |
| Cabinet Cooling Fan | H-FAN-CAB | TC-100-FAN | CAB-FAN-01 | EBM-Papst R4D400 |
Contactors and Relays
| Description | Hobart P/N | Tronair P/N | TLD P/N | Common Cross |
| Main Contactor 200A | H-CON-200 | T-CONT-200A | CON-200-TLD | GE CL04A200 |
| Output Contactor 100A | H-CON-100 | T-CONT-100 | CON-100-TLD | Square D 8910 |
| Control Relay 24VDC | H-REL-24 | T-RELAY-24 | REL-24DC | Allen-Bradley 700 |
Circuit Breakers
Most brands use standardized thermal-magnetic breakers:
- 60A Input: All three use identical 3-pole breakers (Carling/ABB)
- 15A Control: Standard DIN-rail mount across brands
- GFCI: Standard industrial GFCI breakers work universally
Hydraulic Filtration
| Filter Type | Cross-Brand Compatibility |
| Return line | Universal spin-on (Donaldson P550447 or equivalent) |
| Suction strainer | Standard 100-mesh, all brands |
| Oil breather | Standard 10-micron breathers |
Parts That Are NOT Interchangeable
Do NOT attempt to cross-reference:
- Control boards / logic controllers (brand-specific firmware)
- IGBT modules (different gate driver requirements)
- Voltage regulator modules (different sensing circuits)
- Display panels (proprietary communication protocols)
Inventory Strategy
By standardizing on cross-referenceable parts for the items above, a typical 20-unit GPU fleet can reduce inventory SKUs by 35% and cut stock-out incidents by 50%.
