CEM-1205C Equivalent & Substitute Parts

Part Overview

The CEM-1205C is an internally driven magnetic buzzer manufactured by CUI Devices, rated for 5V DC operation with a 12mm through-hole form factor. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The part delivers 85dB sound pressure level at 10cm distance with 2.3kHz frequency output and 35mA supply current consumption.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CEM-1205C is determined by the following critical parameters: rated voltage (5V), magnetic technology, internally driven indicator circuitry, through-hole mounting, PC pin termination, and 12mm diameter form factor. Parts meeting these criteria maintain functional and mechanical compatibility within the original design envelope.

The CEM-1205-IC qualifies as a direct substitute, sharing identical voltage rating, technology, driver type, mounting method, and physical dimensions while maintaining active product status. The PB-12N23P-05Q from Mallory Sonalert Products Inc. provides equivalent performance across voltage range, frequency, SPL, current consumption, and form factor specifications. The OWMB-1295P-24-5 differs in driver circuitry classification (externally driven transducer versus internally driven indicator) and input signal type, placing it in a similar but not directly equivalent category.

Parameter Comparison

Engineering Selection Recommendations

CEM-1205-IC is the primary direct substitute for CEM-1205C. Both components share identical electrical ratings, magnetic technology, internally driven indicator architecture, and physical form factor. The CEM-1205-IC maintains active product status with improved operating temperature range (-40°C to 80°C versus -30°C to 70°C) and reduced current consumption (30mA versus 35mA). Both parts carry ROHS3 compliance and REACH unaffected status.

PB-12N23P-05Q from Mallory Sonalert Products Inc. provides functional equivalence with matching voltage rating, frequency, SPL output, current consumption, and through-hole PC pin configuration. This part maintains active status with extensive inventory availability and identical compliance certifications.

OWMB-1295P-24-5 operates as an externally driven transducer requiring zero-peak signal input rather than DC voltage, representing a different driver architecture. This part is suitable only for designs that can accommodate external drive circuitry and signal generation requirements distinct from the internally driven indicator topology of the CEM-1205C.

Frequently Asked Questions (FAQ)

Q: Can CEM-1205-IC replace CEM-1205C in existing designs without modification?

A: Yes. Both parts share identical voltage rating, magnetic technology, internally driven indicator circuitry, through-hole mounting, PC pin termination, and 12mm diameter dimensions. The CEM-1205-IC exhibits lower current consumption (30mA versus 35mA) and improved operating temperature range, making it a direct functional replacement.

Q: What is the primary difference between CEM-1205-IC and OWMB-1295P-24-5?

A: CEM-1205-IC is an internally driven indicator requiring DC voltage input. OWMB-1295P-24-5 is an externally driven transducer requiring zero-peak signal input. These represent different driver architectures and cannot be substituted without circuit redesign.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. CEM-1205-IC, PB-12N23P-05Q, and OWMB-1295P-24-5 all carry ROHS3 compliance and REACH unaffected status, matching the environmental regulatory requirements of the original CEM-1205C.

Q: How do the physical dimensions compare across substitute parts?

A: All parts maintain the 0.472" (12.00mm) diameter specification. Height variations exist: CEM-1205C measures 0.394" (10.00mm), while CEM-1205-IC and OWMB-1295P-24-5 measure 0.374" (9.50mm), and PB-12N23P-05Q measures 0.354" (9.00mm). These height differences may affect PCB layout clearance in space-constrained applications.

Q: What packaging formats are available for these substitute parts?

A: CEM-1205-IC is supplied in Box packaging. PB-12N23P-05Q is supplied in Tube packaging. OWMB-1295P-24-5 is supplied in Tray packaging. Original CEM-1205C packaging format is not specified in available documentation.
