Sola/Hevi-Duty Type SBE, SBO and SMT control transformers cross to Micron by VA and voltage group. The most common one, E105 (100 VA, 230 x 460 V to 120/115/110 V), crosses to Micron B100BTZ13JK. Sola numbers use a VA code: E060 is 50 VA, E105 is 100 VA, E550 is 500 VA. Read the code, then read across.

Micron universal voltage series through 750 VA; GlobalTRAN (E prefix, 180°C) above that.
Source: Micron Industries control transformer cross reference for EGS Sola/Hevi-Duty Type SBE, SBO, SMT and CE (through 2001), March 2018. Micron units through 750 VA are ImperviTRAN or ValuTRAN, 105°C construction, with provision for 13/32 x 1-1/2 in secondary fusing. The sheet prints some EconoTRAN numbers with a letter O (VF1KOBTZ13JK, EF2KOBTZ13); the Micron numbers use a zero. Sola groups 4, 5 and 6 and the CE series have no direct Micron standard or cross to Micron GlobalTRAN; send the number and we cross it. Linked Micron numbers open the part we list at the same VA and voltage. Our listing can carry an added suffix letter (for example B150BTZ13JKF); we confirm the exact suffix on every quote.
How to read a Sola/Hevi-Duty number
Type SBE numbers start with E, then a VA code (E060 = 50 VA, E095 = 75 VA, E105 = 100 VA, E180 = 150 VA, E225 = 200 VA, E275 = 250 VA, E320 = 300 VA, E380 = 350 VA, E550 = 500 VA, E850 = 750 VA, E1100 = 1 kVA). The letters after the code set the voltage group: none for Group 2, E for Group 1, A for Group 3, N for Group 7, TB for Group 8. Type SBO uses a Y prefix and the real VA (Y1500 = 1.5 kVA). Type SMT uses a T prefix and the VA in every group; the sheet says the 60 Hz SMT units interchange with Micron in the groups above. Primary and secondary fusing suffixes such as 3PB, 11PB and 20PB cross to the same Micron unit; tell us the fusing you need.
Common questions
What Micron transformer replaces Sola/Hevi-Duty E105?
Micron B100BTZ13JK, 100 VA, Group A. Primary 220x440, 230x460 or 240x480 V. Secondary 110, 115 or 120 V.
What replaces Sola/Hevi-Duty E550?
Micron B500BTZ13JK, 500 VA, Group A.
What replaces Sola/Hevi-Duty E105E (24 V)?
Micron B100LP7JK, 100 VA, 120 x 240 V primary, 24 V secondary.
Does Micron cross Sola SMT transformers?
Yes. The sheet says the 60 Hz SMT units interchange with Micron in Groups 1, 2, 3, 7 and 8. Send the SMT number and we match the VA and voltage.
