Parts RT134012 and RT134012F meet all specified electrical and mechanical parameters and are therefore classified as parametric equivalents to the RT234012.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RT234012, RT134012, and RT134012F—are active products manufactured by TE Connectivity Potter & Brumfield Relays and are ROHS3 compliant. The parts are electrically and mechanically equivalent across all specified parameters.

Selection between these parts is based on inventory availability and compliance requirements:

• RT234012: Primary part number with 731 units in stock. REACH status is unaffected.
• RT134012: Parametric equivalent with 1499 units in stock. REACH status is affected.
• RT134012F: Parametric equivalent with 1709 units in stock. REACH status is affected.

All parts operate within the same electrical specifications, temperature range, and switching characteristics. The choice between substitute parts depends on procurement requirements, inventory levels, and regulatory compliance considerations specific to the application.
