A comparison of the T14-1 and XA88 showing the main features for transition.
- Which T14-1 version is equivalent to my XA88 model?
| XA88 version | Equivalent T14-1 version |
| XA88-24DC-1 XA88-24DC-2 | T14-1LW or T14-1LH* |
| XA88-72DC-2 XA88-110DC-1 XA88-110DC-2 | T14-1UW or T14-1 UH |
‘L’ versions operate on 24 to 36 V DC nominal supply
‘H’ versions operate on 72 to 110 V DC nominal supply
In both cases, the normal voltage variations of EN50155:2017 are supported.
*For use on buses and similar vehicles, the XA88-24DC-2 is replaced by the T14-1LB which carries ECE‑R10 and other relevant compliances – please see T14-1LB data sheet (available on request).
- Performance and other features are significantly improved from XA88 to T14-1.

- Which connector should I choose?
The T14-1 range has different connectors from the XA88’s MIL-C-5015 circular connectors. There is now a choice:
Wago 769 (‘W’ versions): robust, easy-to-wire, spring clamp contacts, strong connector retention, cable strain relief plates available, lower cost
Harting HAN-3D (‘H’ versions): industrial, sealed, strong lever-latching connectors, with gold-plated crimp contacts, but at higher cost than the Wago 769.
- Physical and mounting details differ but are similar:
| XA88 | T14-1 | |
| Physical dimensions (Width x Depth x Height) | 251 x 320 x 89 mm | 258 (295 flanges) x 221 x 55 mm |
| Mounting holes | 6 qty M4 tapped holes in underside | 4 qty M4 clear holes mounting flanges at side |
| Mounting orientation | Horizontal with airflow through heatsink | Any orientation, no heatsink |
| Rack tray options | 2U, 300 mm rack tray | 2U, 300 mm rack tray 2U, 430 mm (19-inch) rack tray |
