Compatible Replacement & Equivalent Models
When the 6ES7313-5BE00-0AB0 is discontinued or unavailable, the following models are commonly considered as replacements or functional equivalents:
- 6ES7313-5BF03-0AB0 — Direct successor (CPU 313C-2 DP, V3.3), pin-compatible, expanded memory, recommended upgrade
- 6ES7313-6BF03-0AB0 — CPU 313C-2 PtP, same form factor but RS-422/485 interface instead of DP; suitable if PROFIBUS is not required
- 6ES7314-1AG14-0AB0 — CPU 314, higher performance, no integrated I/O; requires additional SM modules
- 6ES7315-2EH14-0AB0 — CPU 315-2 DP, larger memory and more DP slaves; for expanded systems
- 6ES7318-3EL01-0AB0 — CPU 319-3 PN/DP, top-tier S7-300 CPU; overkill for simple replacements but future-proof
Note: Always verify firmware version, MMC card compatibility, and I/O mapping before substituting CPUs in live systems.

Selection Guide
Use the table below to select the right CPU for your S7-300 application:
- Need integrated I/O + PROFIBUS-DP + 32 KB memory? → 6ES7313-5BE00-0AB0 (this unit) or successor 6ES7313-5BF03-0AB0
- Need integrated I/O + serial (RS-422/485) instead of DP? → 6ES7313-6BF03-0AB0 (CPU 313C-2 PtP)
- Need more memory (96 KB) without integrated I/O? → 6ES7314-1AG14-0AB0 (CPU 314)
- Need PROFINET (PN) interface? → 6ES7315-2FJ14-0AB0 (CPU 315-2 PN/DP)
- Need TIA Portal compatibility? → Consider migrating to S7-1200 (6ES7214 series) or S7-1500
- Replacing a failed unit like-for-like? → 6ES7313-5BF03-0AB0 is the safest drop-in with minimal reconfiguration

Replacement & Compatibility FAQ
Q: Is 6ES7313-5BF03-0AB0 a direct drop-in replacement for 6ES7313-5BE00-0AB0?
A: Yes, in most cases. The BF03 is the successor with the same form factor and pinout. You will need to update the hardware configuration in STEP 7 and re-download the program. The MMC card from the old unit can typically be reused.
Q: Can I use this CPU with TIA Portal?
A: No. The 6ES7313-5BE00-0AB0 is only supported under SIMATIC STEP 7 v5.x. For TIA Portal, you need S7-1200 or S7-1500 series CPUs.
Q: Does this CPU support PROFINET?
A: No. It has MPI and PROFIBUS-DP interfaces only. For PROFINET, select a CPU 315-2 PN/DP or higher.
Q: What MMC card is required?
A: A SIMATIC Micro Memory Card (MMC) is required to store the program. Recommended: 6ES7953-8LF31-0AA0 (4 MB) or 6ES7953-8LJ31-0AA0 (8 MB).
Q: Can I mix this CPU with S7-400 modules?
A: No. S7-300 and S7-400 use different backplane buses and are not cross-compatible.
