Substitute Part Grouping Explanation

Substitution of the CS10-32.000MABJ-UT is determined by the following critical parameters:

• Frequency: 32 MHz (exact match required)
• Load Capacitance: 18pF (exact match required)
• ESR: 50 Ohms (exact match required)
• Package / Case: 2-SMD, No Lead (exact match required)
• Physical Dimensions: 6.00mm x 4.60mm footprint (exact match required)
• Operating Mode: Fundamental (exact match required)

The ABM7-32.000MHZ-D2Y-T meets all critical electrical and mechanical parameters. Variations in frequency tolerance, frequency stability, operating temperature range, and product status do not preclude substitution when the core electrical and mechanical specifications align.

Parameter Comparison

Engineering Selection Recommendations

The ABM7-32.000MHZ-D2Y-T is a direct substitute for the CS10-32.000MABJ-UT based on matching electrical and mechanical specifications. The substitute part offers the following advantages:

• Active product status ensures long-term availability and supply chain continuity
• ROHS3 compliance supports regulatory requirements for new designs
• Extended operating temperature range (-40°C ~ 85°C) provides broader application flexibility compared to the original part (-10°C ~ 60°C)
• Improved frequency tolerance (±20ppm) and frequency stability (±30ppm) exceed the original specifications (±30ppm and ±50ppm respectively)

The substitute part exhibits a maximum seated height of 0.055" (1.40mm) compared to 0.039" (1.00mm) for the original part. This dimensional difference must be evaluated against PCB layout and clearance requirements in the target application.

Frequently Asked Questions (FAQ)

Q: Can the ABM7-32.000MHZ-D2Y-T be used as a direct replacement for the CS10-32.000MABJ-UT?

A: Yes. Both parts share identical frequency (32 MHz), load capacitance (18pF), ESR (50 Ohms), operating mode (Fundamental), and package configuration (2-SMD, No Lead with 6.00mm x 4.60mm footprint). These parameters determine functional compatibility in crystal oscillator applications.

Q: What is the significance of the height difference between these parts?

A: The ABM7-32.000MHZ-D2Y-T has a maximum seated height of 1.40mm compared to 1.00mm for the CS10-32.000MABJ-UT. This 0.40mm difference must be verified against PCB layout constraints, component clearance requirements, and enclosure dimensions in the target application.

Q: Does the extended operating temperature range of the substitute part affect compatibility?

A: No. The substitute part operates across -40°C to 85°C, which encompasses the original part's range of -10°C to 60°C. Applications operating within the original temperature range will function without modification.

Q: Are there compliance differences between these parts?

A: The substitute part is ROHS3 compliant and REACH affected, while the original part is REACH unaffected. Regulatory requirements for the target application must be evaluated to determine if these compliance differences impact part selection.

Q: What packaging formats are available for these parts?

A: The CS10-32.000MABJ-UT is supplied in Cut Tape (CT) & Digi-Reel® format. The ABM7-32.000MHZ-D2Y-T is supplied in Tape & Reel (TR) format. Procurement and assembly processes must accommodate the available packaging options.
