Substitute Part Grouping Explanation

The A-DFF37LPIII/FP-R can be directly substituted with A-DFF 37 LPIII/FP based on identical electrical and mechanical specifications. Both connectors share the same core parameters that define functional compatibility:

• 37-position D-Sub receptacle configuration
• 2-row layout in shell size 4 (DC, C)
• IDC ribbon cable termination method
• 3A current rating at 250V
• Gold-flashed contact finish
• PBT glass-filled dielectric material
• 26-28 AWG wire gauge compatibility
• UL94 V-0 flammability rating
• Operating temperature range of -55°C to 105°C

The primary difference between these parts is packaging format and product status. The substitute part is supplied in tray packaging and maintains active product status, whereas the original part is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The A-DFF 37 LPIII/FP is the direct functional equivalent for the obsolete A-DFF37LPIII/FP-R. Selection of the substitute part is supported by:

• Identical electrical specifications (3A, 250V)
• Matching mechanical configuration (37-position, 2-row, shell size 4)
• Identical termination method (IDC ribbon cable)
• Equivalent contact and dielectric materials
• Same operating temperature range
• Active product status ensuring continued availability
• ROHS3 compliance certification on the substitute part

No additional design modifications or interface changes are required when transitioning from the obsolete part to its substitute.
