Substitute Part Grouping Explanation

Substitution of the ED-21983-000 is determined by strict equivalence across the following critical parameters:

• Impedance: 725 Ohms (electrical matching requirement)
• Frequency Range: 200 Hz ~ 5 kHz (acoustic performance specification)
• Efficiency: 106.00 dBA (sensitivity matching)
• Port Location: Top (mechanical and acoustic design constraint)
• Shape: Rectangular (form factor and mounting compatibility)
• Termination: Solder Pads (assembly interface requirement)
• Physical Dimensions: 0.248" L x 0.169" W x 0.248" H maximum (spatial constraint)
• Technology & Type: Magnetic balanced armature receiver (functional equivalence)
• Compliance: ROHS3 Compliant (regulatory requirement)

The ED-21932-000 meets all substitution criteria as an active product with identical electrical, acoustic, and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The ED-21932-000 is the direct equivalent for the obsolete ED-21983-000. Both components are manufactured by Knowles and share identical electrical, acoustic, and mechanical specifications. The primary distinction is product status: ED-21983-000 is obsolete while ED-21932-000 is active and currently in production.

For new designs or production continuity, the ED-21932-000 is the appropriate selection. Both parts maintain ROHS3 compliance and are functionally interchangeable in applications requiring a 725 Ohm balanced armature receiver with 106 dB sensitivity in the 200 Hz to 5 kHz frequency band.

Frequently Asked Questions (FAQ)

Q: Can ED-21932-000 be used as a direct replacement for ED-21983-000?

A: Yes. Both components are electrically and mechanically identical. The ED-21932-000 is the active production equivalent of the obsolete ED-21983-000.

Q: What are the key parameters that determine substitution eligibility?

A: Impedance (725 Ohms), frequency range (200 Hz ~ 5 kHz), efficiency (106 dBA), port location (top), shape (rectangular), physical dimensions (0.248" L x 0.169" W x 0.248" H), termination type (solder pads), and technology (magnetic balanced armature) must all match exactly.

Q: Are there packaging differences between these parts?

A: ED-21983-000 is packaged in standard format, while ED-21932-000 is supplied in bulk packaging. Both use identical solder pad termination and are suitable for automated assembly processes.

Q: Do both parts meet current compliance requirements?

A: Yes. Both ED-21983-000 and ED-21932-000 are ROHS3 compliant and meet current regulatory standards for electronic components.

Q: What is the physical footprint compatibility?

A: Both components have identical dimensions: 6.30mm length × 4.29mm width × 6.30mm maximum seated height. They are mechanically interchangeable in PCB layouts designed for either part.
