CS10-24.000MABJ-UT Equivalent & Substitute Parts

Part Overview

The CS10-24.000MABJ-UT is a 24 MHz crystal oscillator manufactured by Citizen Finedevice Co Ltd, designed for fundamental mode operation with 18pF load capacitance and 50 Ohms equivalent series resistance. This part is classified as obsolete, making identification of suitable substitute components necessary for ongoing production and maintenance applications. The 2-SMD, no-lead package with compact 6.00mm x 4.60mm footprint serves applications requiring precise frequency reference in a surface-mount configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CS10-24.000MABJ-UT is determined by the following critical parameters:

• Frequency: 24 MHz (exact match required)
• Load Capacitance: 18pF (exact match required)
• Package / Case: 2-SMD, No Lead (exact match required)
• Size / Dimension: 6.00mm x 4.60mm (exact match required)
• Operating Mode: Fundamental (exact match required)

The identified substitute parts meet all mandatory electrical and mechanical parameters. Variations in frequency stability, frequency tolerance, ESR, operating temperature range, and compliance certifications are permitted within the scope of substitution, provided the core parameters remain unchanged.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with current manufacturing status, addressing the obsolescence of the original CS10-24.000MABJ-UT component.

The ABM7-24.000MHZ-D2Y-T offers improved frequency tolerance (±20ppm versus ±30ppm) and enhanced frequency stability (±30ppm versus ±50ppm), with extended operating temperature range (-40°C ~ 85°C). This part is ROHS3 compliant and REACH affected. Height-seated maximum is 1.40mm.

The ECS-240-18-23A-EN-TR maintains frequency tolerance and stability specifications identical to the original part (±30ppm and ±50ppm respectively), with lower ESR (30 Ohms versus 50 Ohms). This part is ROHS3 compliant and REACH unaffected. Height-seated maximum is 1.10mm, closer to the original specification.

Selection between substitutes depends on application requirements for frequency accuracy, temperature operating range, and PCB height constraints.

Frequently Asked Questions (FAQ)

Q: Can the ABM7-24.000MHZ-D2Y-T be used as a direct replacement for the CS10-24.000MABJ-UT?

A: Yes. Both parts share identical frequency (24 MHz), load capacitance (18pF), package type (2-SMD, No Lead), and physical dimensions (6.00mm x 4.60mm). The ABM7 offers superior frequency tolerance and stability specifications with extended operating temperature range.

Q: What is the difference in ESR between the ECS-240-18-23A-EN-TR and the original part?

A: The ECS-240-18-23A-EN-TR has 30 Ohms ESR compared to 50 Ohms in the CS10-24.000MABJ-UT. Lower ESR may improve circuit performance in applications sensitive to series resistance characteristics.

Q: Are there height constraints when substituting these parts?

A: The original part has a maximum seated height of 1.00mm. The ABM7-24.000MHZ-D2Y-T reaches 1.40mm, while the ECS-240-18-23A-EN-TR reaches 1.10mm. PCB layout and component clearance requirements must be evaluated for each substitute.

Q: Do the substitute parts have different moisture sensitivity requirements?

A: The ABM7-24.000MHZ-D2Y-T lists moisture sensitivity as not applicable. The ECS-240-18-23A-EN-TR maintains MSL 1 (Unlimited), matching the original part specification.

Q: Which substitute part is recommended for extended temperature applications?

A: Both substitute parts operate across -40°C ~ 85°C, compared to the original part's -10°C ~ 60°C range. Either substitute supports extended temperature requirements.
