Substitute Part Grouping Explanation

Substitution eligibility for the WP-23502-P49 is determined by strict equivalence across the following critical parameters:

• Microphone type: Electret Condenser
• Output configuration: Analog
• Directional pattern: Omnidirectional
• Frequency response: 100 Hz ~ 4 kHz
• Sensitivity specification: -52dB ±3dB @ 74dB SPL
• Impedance: 4.4 kOhms
• Termination method: Solder Pads
• Physical dimensions: 0.219" L x 0.157" W (5.56mm x 3.99mm)
• Maximum height: 0.089" (2.26mm)
• Environmental rating: Waterproof

The WP-23502-000 meets all substitution criteria as a direct equivalent from the same manufacturer within the WP series, with identical electrical and mechanical specifications. The primary distinction is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The WP-23502-000 is the direct substitute for the obsolete WP-23502-P49. Both components share identical electrical performance characteristics and mechanical dimensions, ensuring functional compatibility in existing circuit designs.

The WP-23502-000 carries Active product status, providing assured long-term availability and supply chain continuity. This component is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

The substitute part includes documented voltage specifications (1.3 V rated, 1.3 V ~ 10 V operating range) and supply current (50 µA), which were not provided for the original part. These parameters are consistent with standard electret condenser microphone operation and do not introduce design constraints for applications previously using the WP-23502-P49.
