Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HCPL-091J is determined by strict equivalence across the following critical parameters:

• Isolation voltage rating: 2500Vrms
• Channel configuration: 4 channels with 2/2 input distribution
• Data rate: 110MBd
• Common mode transient immunity: 15kV/µs minimum
• Propagation delay specifications: 15ns maximum (tpLH and tpHL)
• Pulse width distortion: 3ns maximum
• Supply voltage range: 3V to 5.5V
• Package type: 16-SOIC with 0.154" width (3.90mm)
• Mounting configuration: Surface mount

The HCPL-091J-000E meets all these criteria and qualifies as a parametric equivalent. Both parts share identical electrical performance characteristics, mechanical dimensions, and functional specifications, enabling direct substitution in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

Both the HCPL-091J and HCPL-091J-000E are active production parts from Broadcom Limited with identical electrical and mechanical specifications. The primary distinction between these parts is regulatory compliance status: the HCPL-091J-000E carries ROHS3 compliance, while the HCPL-091J is RoHS non-compliant. Selection between these equivalents should be based on application requirements for environmental and regulatory compliance. Both parts maintain identical isolation performance, data rate capability, and package configuration. Inventory availability is adequate for both variants, with the HCPL-091J offering 1827 units and the HCPL-091J-000E offering 1580 units in current stock.
