Key Parameters

Substitute Part Grouping Explanation

Substitution of the ED-30003-000 is determined by the following critical parameters:

• Receiver Type & Technology: Both parts must be Balanced Armature Receivers with Magnetic technology to maintain functional equivalence
• Impedance Tolerance: The substitute impedance of 87 Ohms falls within acceptable tolerance of the original 85 Ohms specification
• Frequency Range Compatibility: The substitute frequency range of 200 Hz ~ 4.4 kHz encompasses the original 200 Hz ~ 4 kHz range
• Termination Method: Solder pad termination must be maintained for circuit integration compatibility
• Mechanical Form Factor: Rectangular shape and port configuration must support the original mechanical design
• Compliance & Status: The substitute must maintain ROHS3 compliance and possess Active product status for ongoing availability

The ED-23147-000 satisfies all substitution criteria as an Active equivalent within the ED series from Knowles.

Parameter Comparison

Engineering Selection Recommendations

The ED-23147-000 is the designated manufacturer-recommended substitute for the obsolete ED-30003-000. Selection of this equivalent is supported by:

• Active Product Status: The ED-23147-000 maintains Active status, ensuring long-term availability and supply chain reliability
• Regulatory Compliance: Both components maintain ROHS3 compliance, satisfying environmental and regulatory requirements
• Electrical Compatibility: Impedance variance of 2 Ohms and frequency range overlap provide functional equivalence within standard engineering tolerances
• Mechanical Integration: Identical rectangular form factor and solder pad termination enable direct circuit board integration
• Manufacturer Certification: Knowles designation as the recommended substitute confirms engineering validation

The primary design consideration is the port location change from Side to Top orientation. Circuit board layout and acoustic chamber design must accommodate this mechanical difference during integration.

Frequently Asked Questions (FAQ)

Q: Can the ED-23147-000 be used as a direct replacement for ED-30003-000?

A: The ED-23147-000 is electrically and mechanically compatible as a substitute. The primary design consideration is the port location change from Side to Top. Circuit board layout and acoustic enclosure design must be evaluated to accommodate this orientation difference.

Q: What is the impedance difference between these parts?

A: The ED-30003-000 specifies 85 Ohms while the ED-23147-000 specifies 87 Ohms. This 2 Ohm variance is within standard engineering tolerance for balanced armature receiver applications and does not affect functional compatibility.

Q: Does the frequency range difference affect substitution?

A: The ED-23147-000 frequency range of 200 Hz ~ 4.4 kHz encompasses the original ED-30003-000 range of 200 Hz ~ 4 kHz. The extended upper frequency response of the substitute provides equivalent or improved performance characteristics.

Q: Are there packaging differences between these parts?

A: The ED-30003-000 is supplied in standard packaging while the ED-23147-000 is supplied in Bulk packaging. Procurement specifications should reflect the required packaging format for production requirements.

Q: What compliance certifications apply to both parts?

A: Both the ED-30003-000 and ED-23147-000 maintain ROHS3 compliance. The ED-23147-000 additionally carries REACH Unaffected status. Both components are classified under ECCN EAR99 and HTSUS 8518.29.8000.

Q: Why is the ED-30003-000 classified as Obsolete?

A: Obsolete status indicates the part is no longer in active production. The ED-23147-000 serves as the active equivalent to maintain design continuity and ensure component availability for ongoing applications.
