CS10-16.000MABJ-UT Equivalent & Substitute Parts

Part Overview

The CS10-16.000MABJ-UT is a 16 MHz fundamental mode crystal oscillator manufactured by Citizen Finedevice Co Ltd, designed for surface mount applications requiring precise frequency control. This part operates at 16 MHz with ±30ppm frequency tolerance and 18pF load capacitance in a compact 2-SMD, No Lead package measuring 6.00mm x 4.60mm. The product is currently obsolete, making equivalent substitute parts necessary for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution for the CS10-16.000MABJ-UT is determined by strict alignment of electrical and mechanical parameters. The critical substitution criteria are:

Frequency: 16 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)
Mounting Type: Surface Mount (exact match required)
Operating Mode: Fundamental (exact match required)

Two substitute parts meet these core requirements: ABM7-16.000MHZ-D2Y-T and ECS-160-18-23A-EN-TR. Both maintain identical frequency, load capacitance, package configuration, and physical dimensions as the original part.

Engineering Selection Recommendations

Both substitute parts are active products with current manufacturing support, addressing the obsolescence of the original CS10-16.000MABJ-UT.

ABM7-16.000MHZ-D2Y-T offers improved frequency stability (±30ppm vs. ±50ppm) and tighter frequency tolerance (±20ppm vs. ±30ppm), with extended operating temperature range (-40°C ~ 85°C). This part is ROHS3 compliant and carries REACH Affected status. The maximum seated height is 1.40mm, which exceeds the original part's 1.00mm specification.

ECS-160-18-23A-EN-TR maintains identical frequency tolerance (±30ppm) and frequency stability (±50ppm) as the original part, with ROHS3 compliance and REACH Unaffected status. The ESR specification is 60 Ohms compared to the original 50 Ohms. Maximum seated height is 1.10mm, closer to the original specification. This part provides the most direct electrical and mechanical alignment with the original CS10-16.000MABJ-UT.

Selection between these substitutes depends on system requirements for frequency stability, operating temperature range, and PCB height constraints.

Frequently Asked Questions (FAQ)

Q: Can ABM7-16.000MHZ-D2Y-T be used as a direct replacement for CS10-16.000MABJ-UT?

A: Yes. Both parts share identical frequency (16 MHz), load capacitance (18pF), package configuration (2-SMD, No Lead), and physical dimensions (6.00mm x 4.60mm). The ABM7 offers superior frequency stability and extended temperature range. The increased maximum seated height (1.40mm vs. 1.00mm) must be verified against PCB layout constraints.

Q: What is the difference in ESR between ECS-160-18-23A-EN-TR and the original part?

A: ECS-160-18-23A-EN-TR specifies 60 Ohms ESR compared to the original 50 Ohms. This 10 Ohm difference must be evaluated within the context of the circuit design and oscillator load requirements.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both ABM7-16.000MHZ-D2Y-T and ECS-160-18-23A-EN-TR are ROHS3 compliant.

Q: Which substitute part has the closest physical dimensions to the original?

A: Both substitute parts maintain the same length (6.00mm) and width (4.60mm) as the original CS10-16.000MABJ-UT. ECS-160-18-23A-EN-TR has a maximum seated height of 1.10mm, which is closer to the original 1.00mm specification than the ABM7's 1.40mm.

Q: What is the difference in operating temperature range?

A: The original CS10-16.000MABJ-UT operates from -10°C to 60°C. Both substitute parts extend this range to -40°C to 85°C, providing broader environmental compatibility.

Q: Does REACH status affect component selection?

A: ABM7-16.000MHZ-D2Y-T carries REACH Affected status, while ECS-160-18-23A-EN-TR is REACH Unaffected. Selection depends on regulatory requirements specific to the application and end market.
