MAS800 Equivalent & Substitute Parts

Part Overview

The MAS800 is an internally driven piezo buzzer rated for 12V DC operation, designed for indicator applications requiring audible signaling. This component features a 26mm diameter through-hole form factor with PC pin termination, delivering 103dB sound pressure level at 10cm distance. The MAS800 is classified as obsolete, necessitating identification of active equivalent parts to ensure design continuity and procurement availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAS800 is determined by electrical and mechanical parameter equivalence within the internally driven piezo buzzer category. The critical parameters governing substitutability are:

• Voltage rating and operating range (12V, 9-12V tolerance)
• Frequency output (2.7kHz single tone)
• Sound pressure level performance (103dB @ 12V, 10cm)
• Current consumption (50mA)
• Physical form factor (26mm diameter, 21.90mm height maximum)
• Mounting configuration (through-hole with PC pin termination)
• Driver circuitry type (internally driven indicator)

The MAS800Q qualifies as a direct substitute based on identical electrical specifications, mechanical dimensions, and functional characteristics. The primary distinction is product status: MAS800Q is active and RoHS3 compliant, whereas MAS800 is obsolete and RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

The MAS800Q is the direct equivalent for MAS800 applications. Both components share identical electrical performance, frequency output, sound pressure level, and physical dimensions. Selection between these parts is determined by regulatory and compliance requirements rather than functional differences.

For new designs and production runs, MAS800Q is the appropriate choice due to active product status and RoHS3 compliance. This ensures long-term supply chain stability and alignment with current environmental regulations.

For legacy system maintenance where MAS800 components are already deployed, MAS800Q provides pin-compatible replacement without circuit modification, as all electrical and mechanical parameters remain equivalent.

Frequently Asked Questions (FAQ)

Q: Can MAS800Q replace MAS800 in existing designs?

A: Yes. MAS800Q is electrically and mechanically identical to MAS800. Both operate at 12V rated voltage with 9-12V tolerance, deliver 103dB SPL at 2.7kHz, and share the same 26mm through-hole form factor with PC pin termination. Direct substitution requires no circuit changes.

Q: What is the primary reason to transition from MAS800 to MAS800Q?

A: MAS800 is obsolete with limited inventory availability. MAS800Q is an active product with higher stock levels and RoHS3 compliance, ensuring procurement reliability and regulatory alignment for current manufacturing standards.

Q: Are there packaging differences between MAS800 and MAS800Q?

A: MAS800 is supplied in standard packaging, while MAS800Q is available in bulk packaging. Both contain identical components with equivalent electrical and mechanical specifications.

Q: What are the critical parameters for confirming substitutability?

A: Voltage rating (12V), operating voltage range (9-12V), frequency (2.7kHz), sound pressure level (103dB @ 12V, 10cm), current consumption (50mA), mounting type (through-hole), termination style (PC pins), and physical dimensions (26mm diameter, 21.90mm maximum height) must all match for direct substitution.

Q: Is circuit redesign necessary when switching from MAS800 to MAS800Q?

A: No. Both parts are internally driven piezo buzzers with identical electrical characteristics and pin configurations. They are direct drop-in replacements requiring no circuit modifications.
