DSC1001CE2-100.0000 MEMS Oscillator Equivalent & Substitute Parts

Part Overview

The DSC1001CE2-100.0000 is a 100 MHz MEMS-based XO (Standard) oscillator manufactured by Microchip Technology. This component operates across a 1.8V to 3.3V supply range with CMOS output, designed for applications requiring stable frequency generation with low power consumption. The part is currently in active production status with 814 units in stock. Substitute parts may be required due to supply constraints, lead time considerations, or specific application requirements that align with alternative qualified components.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DSC1001CE2-100.0000 is determined by strict alignment of the following critical parameters:

Core Electrical Requirements:

• Frequency: 100 MHz (exact match required)
• Output Type: CMOS
• Supply Voltage Range: 1.8V ~ 3.3V (minimum overlap required)
• Base Resonator: MEMS

Physical & Mechanical Requirements:

• Package Type: 4-pin surface mount configuration
• Footprint Dimensions: 3.20mm x 2.50mm (0.126" L x 0.098" W)
• Height - Seated (Max): 0.90mm
• Mounting Type: Surface Mount

Compliance & Regulatory:

• RoHS3 Compliance
• MSL Rating: 1 (Unlimited)

The ASEMB-100.000MHZ-LY-T from Abracon LLC meets all core electrical and mechanical requirements. Both components share identical frequency, CMOS output, overlapping supply voltage range, MEMS resonator technology, matching footprint dimensions, and equivalent compliance certifications. Differences in frequency stability (±10ppm vs ±25ppm), operating temperature range (-40°C ~ 85°C vs -20°C ~ 70°C), and maximum supply current (16mA vs 8.7mA) do not preclude substitution but represent performance variations that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the DSC1001CE2-100.0000 and ASEMB-100.000MHZ-LY-T are active production components with full RoHS3 compliance and MSL 1 ratings, qualifying them for equivalent use in applications requiring 100 MHz CMOS oscillators with 1.8V to 3.3V operation.

Selection Criteria Based on Application Requirements:

The Microchip DSC1001CE2-100.0000 is appropriate for applications where maximum supply current efficiency is critical, with a 8.7mA maximum specification. This component operates within a -20°C to 70°C temperature range and maintains ±25ppm frequency stability.

The Abracon ASEMB-100.000MHZ-LY-T is appropriate for applications requiring extended operating temperature coverage (-40°C to 85°C) or tighter frequency stability (±10ppm). The higher maximum supply current specification (16mA) must be accommodated in power budget calculations.

Both components share identical physical footprints, electrical interfaces, and regulatory compliance status, enabling direct substitution at the PCB assembly level without design modification.

Frequently Asked Questions (FAQ)

Q: Can the ASEMB-100.000MHZ-LY-T directly replace the DSC1001CE2-100.0000 on an existing PCB?

A: Yes. Both components share identical footprint dimensions (3.20mm x 2.50mm), height (0.90mm), and pin configuration for 4-pin surface mount packages. The CMOS output, supply voltage range (1.8V ~ 3.3V), and frequency (100 MHz) are identical. PCB layout and schematic connections require no modification.

Q: What is the difference between 4-VDFN and 4-SMD, No Lead packaging?

A: Both designations refer to 4-pin surface mount packages with no leads. The functional and dimensional specifications are equivalent for this application. The terminology difference reflects manufacturer nomenclature conventions.

Q: Does the higher frequency stability of the Abracon part (±10ppm vs ±25ppm) affect compatibility?

A: No. Tighter frequency stability is a performance enhancement, not a compatibility issue. Applications designed for ±25ppm tolerance will operate correctly with ±10ppm components. Applications requiring ±10ppm stability cannot use the Microchip part.

Q: The Abracon part has higher maximum supply current (16mA vs 8.7mA). Is this a concern?

A: This represents a worst-case specification difference. The actual operating current depends on load conditions and duty cycle. Verify that your power supply and current-limiting circuitry can accommodate 16mA maximum draw. If your design is constrained to 8.7mA, the Microchip part is required.

Q: Are both parts suitable for industrial temperature applications?

A: The Abracon ASEMB-100.000MHZ-LY-T operates across -40°C to 85°C, covering extended industrial temperature ranges. The Microchip DSC1001CE2-100.0000 operates across -20°C to 70°C, suitable for commercial and light industrial applications. Select based on your specific operating temperature requirements.

Q: Do both parts have identical moisture sensitivity handling requirements?

A: Yes. Both components carry MSL 1 (Unlimited) ratings, indicating no moisture sensitivity restrictions. Standard handling procedures for surface mount components apply.
