ASM SIPLACE 00355989 is identified in placement-machine parts references as a vacuum generator / vacuum distributor used in the placement-head vacuum system. Because public references use both descriptions, the exact P/N should remain the primary purchasing identity.
Do not confuse 00355989 with the near-identical P/N 00335989. The latter is separately documented as VACUUM GENERATOR COMPLETE/DLM1, so the complete installed label should be verified before ordering.
00355989 Vacuum Specifications
| Part Number | 00355989 |
| Part Type | Vacuum generator / vacuum distributor |
| Application Area | Placement-head vacuum system |
| Confusing P/N | 00335989 — complete DLM1 vacuum generator |
| Selection Risk | Near-identical P/Ns identify separately documented vacuum service parts |
| Key Matching Point | Confirm exact label and installed head configuration |
Weak or unstable suction should first be separated from the surrounding pneumatic path. Air supply, hose condition, leakage, seals and downstream vacuum connections can affect suction performance without proving that the generator or distributor itself has failed.
For 00355989, use the complete installed label and placement-head configuration as the primary matching references. A generic vacuum-generator description or a similar-looking P/N is not sufficient to confirm the correct part.
Send a clear label photo, placement-head information, installation photos and the observed vacuum symptom for remote technical troubleshooting. Other pneumatic and vacuum head components are available under ASM SIPLACE SMT head parts.
