How to Verify SR70.TCT Before Ordering

Datasheet and parameter checks

  • Confirm the full manufacturer part number, not only a shortened search keyword.
  • Compare package, pinout, dimensions, voltage or rating fields, temperature range and compliance wording against the released BOM.
  • Use the manufacturer datasheet or drawing for electrical and mechanical limits before approving a substitute.

RFQ fields SENICO needs

  • Send exact part number, manufacturer, quantity, target delivery date, destination and required packaging.
  • State whether alternates are allowed, and list any date-code, certificate, traceability or customer AVL requirement.
  • Keep exact stock, factory lead time and proposed alternatives in separate quote lanes.

For SR70.TCT, SENICO recommends checking manufacturer marking, package, date code, requested quantity, approved vendor requirements and replacement risk before issuing a purchase order. If a supplier suggests an equivalent, record the changed fields and approval owner before comparing price.

We do not treat displayed data as a real-time stock or price commitment. The RFQ reply is the verified commercial reference.
