EAS-4P15SA Equivalent & Substitute Parts

Part Overview

The EAS-4P15SA is an 8 Ohm general purpose speaker manufactured by Panasonic Electronic Components, rated for 100 mW power handling with a top-mounted round port configuration. This component operates across a frequency range of 530 Hz to 3 kHz with a sound pressure level of 92 dBA at 1W/500mm testing conditions. The product is currently obsolete, making equivalent or substitute components necessary for new designs or system replacements requiring similar acoustic performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EAS-4P15SA is determined by the following critical parameters:

• Impedance Match: 8 Ohms (electrical compatibility requirement)
• Port Location: Top-mounted configuration (mechanical and acoustic requirement)
• Shape: Round form factor (mechanical fit requirement)
• Technology: Magnetic speaker construction (functional requirement)
• Frequency Range Compatibility: Minimum coverage of 530 Hz lower bound
• Power Rating: Rated power must accommodate system requirements

The CLS0402MA-1-L152 from CUI Devices meets these core substitution criteria. While this substitute exhibits higher power handling (500 mW rated, 1 W maximum) and extended frequency response (530 Hz ~ 6 kHz), it maintains the essential electrical and mechanical parameters required for functional equivalence in applications where the EAS-4P15SA is specified.

Parameter Comparison

Engineering Selection Recommendations

The CLS0402MA-1-L152 is an active product with current manufacturing support and availability, addressing the obsolescence status of the EAS-4P15SA. Both components share identical impedance (8 Ohms) and self-resonant frequency (530 Hz), establishing electrical compatibility for direct substitution in 8 Ohm speaker circuits.

The CLS0402MA-1-L152 provides enhanced power handling capability (500 mW rated versus 100 mW), which allows operation in higher-power applications without derating. The extended frequency response (up to 6 kHz versus 3 kHz) provides broader acoustic coverage. The substitute maintains top-port configuration and round form factor, preserving mechanical compatibility in existing enclosure designs.

Physical dimensions differ: the CLS0402MA-1-L152 is smaller in diameter (40mm versus 45mm) and significantly lower in profile (5.30mm versus 15.80mm seated height). Termination differs from solder pads to wire leads, requiring circuit board layout and assembly process modifications.

The CLS0402MA-1-L152 carries RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements for new product designs.

Frequently Asked Questions (FAQ)

Q: Can the CLS0402MA-1-L152 directly replace the EAS-4P15SA in existing designs?

A: Electrical substitution is valid due to matching 8 Ohm impedance and identical self-resonant frequency. Mechanical substitution requires verification of physical space constraints, as the CLS0402MA-1-L152 has a smaller diameter (40mm versus 45mm) and lower profile (5.30mm versus 15.80mm). Termination conversion from solder pads to wire leads requires circuit board redesign.

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

A: Impedance (8 Ohms), port location (top-mounted), shape (round), technology (magnetic), and self-resonant frequency (530 Hz) are the primary criteria. Power rating and frequency range extensions do not prevent substitution but may alter system performance characteristics.

Q: Is the CLS0402MA-1-L152 suitable for applications requiring 100 mW power handling?

A: Yes. The CLS0402MA-1-L152 is rated for 500 mW continuous power, providing substantial margin above 100 mW requirements. This allows operation without thermal or acoustic stress in applications originally designed for the EAS-4P15SA.

Q: How do the efficiency ratings compare?

A: The EAS-4P15SA produces 92 dBA at 1W/500mm testing conditions. The CLS0402MA-1-L152 produces 90 dBA at 500mW/500mm testing conditions. Direct comparison is not applicable due to different test power levels; however, both components operate within typical speaker efficiency ranges for their respective categories.

Q: What packaging and supply considerations apply?

A: The EAS-4P15SA is obsolete with limited remaining inventory (840 pcs). The CLS0402MA-1-L152 is an active product with current manufacturing and higher inventory availability (1803 pcs). Both carry MSL 1 (Unlimited) moisture sensitivity classification.
