B5092

Cold-cathode numeric or character indicator cross-referenced to RFT Z5600M in a German comparison catalog. Because the source warns that comparable types are not necessarily electrically identical, the RFT mapping is useful functional evidence rather than exact-rating evidence.

Description

B5092 is a cold-cathode numeric or character indicator tube listed in the supplied German comparison catalog as comparable to RFT type Z5600M. The catalog provides electrical and mechanical data for that RFT type, including anode striking, maintaining, and operating limits. The source cautions that comparable types are not necessarily electrically identical, so the mapped RFT values are retained as comparison data rather than asserted as exact original-manufacturer ratings.
