DSC1124CE1-100.0000 Equivalent & Substitute Parts

Part Overview

The DSC1124CE1-100.0000 is a 100 MHz MEMS-based XO (Standard) oscillator manufactured by Microchip Technology. It operates across a 2.25V to 3.6V supply range with HCSL output, Enable/Disable functionality, and ±50ppm frequency stability. The device is housed in a 6-SMD, No Lead package measuring 3.20mm × 2.50mm with a maximum seated height of 0.90mm. This part is Active status and ROHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DSC1124CE1-100.0000 is determined by the following critical parameters:

• Frequency Match: 100 MHz output frequency
• Output Compatibility: HCSL output standard
• Package Compatibility: 6-SMD, No Lead form factor with matching 3.20mm × 2.50mm footprint
• Enable/Disable Function: Presence of enable/disable control capability
• Frequency Stability: ±50ppm tolerance
• Compliance: ROHS3 and REACH compliance status

The NX3241E0100.000000 from Diodes Incorporated meets these substitution criteria. Both parts share identical frequency, output type, package form factor, footprint dimensions, function capability, and frequency stability specification. Compliance certifications are equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the DSC1124CE1-100.0000 and NX3241E0100.000000 are Active status products with ROHS3 compliance and REACH unaffected status. Selection between these parts is based on application-specific requirements:

The DSC1124CE1-100.0000 operates across a wider supply voltage range (2.25V ~ 3.6V) and exhibits lower maximum supply current (42mA active, 22mA disabled). It is suitable for applications requiring operation below 3.3V or with strict power consumption constraints.

The NX3241E0100.000000 operates at a fixed 3.3V supply with an extended operating temperature range (-40°C ~ 85°C) compared to the DSC1124CE1-100.0000 (-20°C ~ 70°C). Higher supply current specifications (70mA active, 40mA disabled) and slightly increased seated height (1.05mm versus 0.90mm) are design considerations for space-constrained or low-power applications.

Frequently Asked Questions (FAQ)

Q: Can the NX3241E0100.000000 replace the DSC1124CE1-100.0000 in all applications?

A: Substitution is valid when the application supply voltage is 3.3V and the operating temperature range of -40°C ~ 85°C is acceptable. The increased seated height (1.05mm versus 0.90mm) must be verified against PCB clearance requirements. Higher supply current consumption must be evaluated against power budget constraints.

Q: What is the primary difference between these oscillators?

A: The DSC1124CE1-100.0000 uses a MEMS resonator with a 2.25V ~ 3.6V supply range, while the NX3241E0100.000000 uses a crystal resonator with a fixed 3.3V supply. Both deliver identical 100 MHz HCSL output with ±50ppm stability and Enable/Disable functionality.

Q: Are the package footprints identical?

A: Both parts use 6-SMD, No Lead packaging with identical 3.20mm × 2.50mm footprints. The seated height differs: DSC1124CE1-100.0000 is 0.90mm maximum, while NX3241E0100.000000 is 1.05mm maximum. PCB layout clearance must accommodate the taller profile.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the DSC1124CE1-100.0000 and NX3241E0100.000000 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What supply voltage should I use for the NX3241E0100.000000?

A: The NX3241E0100.000000 operates at 3.3V. It does not support the 2.25V ~ 3.6V range of the DSC1124CE1-100.0000. Applications requiring sub-3.3V operation must use the DSC1124CE1-100.0000.
