Substitute Part Grouping Explanation

Substitution eligibility for the DSC1001AL5-100.0000T is determined by strict alignment with the following critical parameters:

• Frequency: 100 MHz (exact match required)
• Base Resonator: MEMS technology
• Type: XO (Standard)
• Output: CMOS or LVCMOS (compatible logic families for 1.8V ~ 3.3V operation)
• Voltage Supply Range: 1.8V ~ 3.3V
• Frequency Stability: ±10ppm
• Operating Temperature: -40°C ~ 105°C
• Function: Standby (Power Down) capability
• Mounting: Surface Mount
• Package Footprint: 7.00mm x 5.00mm with 0.90mm maximum height
• Compliance: ROHS3 Compliant, MSL 1

The ASVMB-100.000MHZ-XY-T from Abracon LLC meets all substitution criteria. Both parts share identical frequency, MEMS resonator technology, supply voltage range, frequency stability, operating temperature, and physical dimensions. The output difference (CMOS vs. LVCMOS) is compatible within the specified voltage range, as LVCMOS is a subset of CMOS logic levels for low-voltage applications.

Parameter Comparison

Engineering Selection Recommendations

Both the DSC1001AL5-100.0000T and ASVMB-100.000MHZ-XY-T are active production components with ROHS3 compliance and MSL 1 rating, indicating equivalent environmental and regulatory standing. Selection between these parts should be based on:

• Supply Chain Availability: DSC1001AL5-100.0000T has 1094 units in stock; ASVMB-100.000MHZ-XY-T has 1739 units in stock.
• Current Consumption: The DSC1001AL5-100.0000T operates at 8.7mA maximum supply current, while the ASVMB-100.000MHZ-XY-T operates at 16mA maximum. Applications with strict power budgets should prioritize the Microchip part.
• Package Variant: Both parts maintain identical footprint dimensions (7.00mm x 5.00mm x 0.90mm). The VDFN and SMD package variants are mechanically interchangeable for PCB placement.
• Output Logic Compatibility: LVCMOS output (Abracon) is fully compatible with CMOS input receivers across the 1.8V ~ 3.3V supply range.

Frequently Asked Questions (FAQ)

Q: Can the ASVMB-100.000MHZ-XY-T replace the DSC1001AL5-100.0000T in existing designs?

A: Yes. Both parts share identical frequency (100 MHz), supply voltage range (1.8V ~ 3.3V), frequency stability (±10ppm), operating temperature range (-40°C ~ 105°C), and physical dimensions (7.00mm x 5.00mm x 0.90mm). The LVCMOS output is compatible with CMOS input receivers. The primary difference is higher supply current (16mA vs. 8.7mA), which must be evaluated against application power budgets.

Q: Are the package types interchangeable?

A: The 4-VDFN Exposed Pad (Microchip) and 4-SMD, No Lead Exposed Pad (Abracon) maintain identical footprint dimensions and pin assignments. Both are surface-mount packages with the same 7.00mm x 5.00mm footprint and 0.90mm maximum height, allowing direct PCB layout compatibility.

Q: What is the difference between CMOS and LVCMOS output?

A: CMOS is a general-purpose logic family, while LVCMOS (Low-Voltage CMOS) is optimized for low-voltage operation. Both are compatible within the 1.8V ~ 3.3V supply range specified for these oscillators. LVCMOS output levels conform to CMOS input thresholds across this voltage range.

Q: Do both parts support standby mode?

A: Yes. Both the DSC1001AL5-100.0000T and ASVMB-100.000MHZ-XY-T include standby (power-down) functionality with identical disable current specifications (15µA maximum).

Q: Are there any compliance or regulatory differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity level) ratings. Both are classified under ECCN EAR99 and HTSUS 8542.39.0001.

Q: Which part should I select for new designs?

A: Selection depends on application requirements. For power-sensitive applications, the DSC1001AL5-100.0000T (8.7mA) is preferred. For applications where supply current is not critical, the ASVMB-100.000MHZ-XY-T offers higher inventory availability (1739 units vs. 1094 units).
