The 30 mm width fits the standard 3RK3 backplane slot — no additional DIN rail space beyond the module footprint. ## Substance prohibitance and compliance baseline Substance prohibitance date is 05/01/2012 — this marks the RoHS compliance transition point for the part. The documentation package should include Siemens' declaration of conformity and the material composition statement supporting the audit trail for 21 CFR Part 11 data integrity requirements. No UL, CSA, or IEC certification marks appear on the record. For a clean-room or sterile-fill qualification, the buyer should request the Siemens certificate of compliance at RFQ to confirm the part meets the site's regulatory jurisdiction. ## Sourcing posture for the BOM line The 3RK1903-3AB10 is sourced to order against the BOM quantity through independent distribution channels. No official successor or pin-compatible alternative is recorded for this order code. If a second-source gate review is required, the buyer should provide the target shutdown group coding and backplane slot count to the sourcing desk for cross-reference validation.","metaTitle":"Siemens 3RK1903-3AB10 F-CM Contact Multiplier","metaDescription":"Siemens 3RK1903-3AB10 F-CM contact multiplier for shutdown groups SG1-SG6, 30 mm width.
