Parameter Comparison

Engineering Selection Recommendations

The AS07104PO-WR-R is the direct equivalent for the obsolete AS07104PO-WR. Both parts share identical electrical specifications, mechanical dimensions, and functional characteristics. The primary distinction is product status and regulatory compliance.

The AS07104PO-WR-R is currently in active production status, ensuring availability for new designs and ongoing procurement. Additionally, the AS07104PO-WR-R meets ROHS3 compliance requirements, whereas the original AS07104PO-WR is RoHS non-compliant. For applications subject to RoHS regulations or requiring components from active product lines, the AS07104PO-WR-R is the appropriate selection.

Both parts are manufactured by PUI Audio, Inc., and maintain identical performance characteristics across all electrical and mechanical parameters.

Frequently Asked Questions (FAQ)
