NTE's replacement list for it includes the MPSA12, MPSA13, MPSA14 and MPSA25 through MPSA29, among others. The MPSA13 is rated only 30V, so it can substitute only where 30V is sufficient. Verify the marking and ratings against the original circuit before use.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eQ\u0026amp;A\u003c\/strong\u003e\u003cbr\u003eQ: What does the ECG-46 replace? A: NTE lists the NTE46 \/ ECG46 as a replacement for the MPSA13, among other Darlington types.\u003cbr\u003eQ: Can an MPSA13 replace an ECG-46? A: Only if the circuit needs 30V or less; the ECG-46 is rated 100V.\u003cbr\u003eQ: How many are included?
