Key Parameters

Substitute Part Grouping Explanation

Substitution of D-Sub 50 position receptacle connectors is determined by strict equivalence across the following critical parameters: connector style (D-Sub), connector type (receptacle with female sockets), position count (50), row configuration (3 rows), shell size and layout (5 DD, D), mounting method (through hole), termination technology (press-fit), shell material and finish (steel, tin plated), contact finish (gold), contact material (copper alloy), flange configuration (unthreaded housing/shell), and operating temperature range (-55°C to 105°C). The substitute part 5747143-2 maintains identical electrical and mechanical specifications to the primary part 747143-2, with the distinction that 5747143-2 carries RoHS Compliant status while 747143-2 is RoHS non-compliant. Both parts are manufactured by TE Connectivity AMP Connectors within the AMPLIMITE HD-20 series and are classified as active products.

Parameter Comparison

Engineering Selection Recommendations

Both 747143-2 and 5747143-2 are active products manufactured by TE Connectivity AMP Connectors and are electrically and mechanically equivalent. Selection between these parts is determined by regulatory and compliance requirements. The primary part 747143-2 is RoHS non-compliant, making it suitable for applications where RoHS compliance is not mandated. The substitute part 5747143-2 is RoHS Compliant, making it the appropriate selection for applications subject to RoHS directives or customer specifications requiring RoHS compliance. Both parts carry identical UL94 V-0 flammability ratings, ECCN classification (EAR99), and HTSUS codes. Inventory availability differs between the two parts, with 747143-2 having 928 units in stock and 5747143-2 having 846 units in stock. Component selection should be based on the specific regulatory environment and compliance requirements of the end application.

Frequently Asked Questions (FAQ)

Q: Are 747143-2 and 5747143-2 electrically interchangeable?
