AX5HCF1-100.0000C Equivalent & Substitute Parts

Part Overview

The AX5HCF1-100.0000C is a 100 MHz XO (Standard) HCSL Oscillator manufactured by Abracon LLC, part of the ClearClock™ AX5 series. This component operates at 1.8V with Enable/Disable functionality and is housed in an 8-SMD, No Lead package. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX5HCF1-100.0000C is determined by the following critical parameters:

• Frequency: 100 MHz (exact match required)
• Output Type: HCSL (exact match required)
• Supply Voltage: 1.8V (exact match required)
• Function: Enable/Disable capability (exact match required)
• Frequency Stability: ±20ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Base Resonator: Crystal (exact match required)
• Type: XO (Standard) (exact match required)

The two substitute parts listed—510LCA100M000BAG and 511LCA100M000BAG—both meet these critical electrical and functional parameters. However, they differ in package configuration (6-SMD, No Lead versus 8-SMD, No Lead) and maximum supply current specifications, which may affect PCB layout and thermal design considerations.

Parameter Comparison

Engineering Selection Recommendations

Both 510LCA100M000BAG and 511LCA100M000BAG are active products from Skyworks Solutions Inc., providing design continuity for the discontinued AX5HCF1-100.0000C. Both substitutes maintain electrical equivalence across all critical parameters: 100 MHz frequency, HCSL output, 1.8V supply, Enable/Disable function, ±20ppm stability, and -40°C to 85°C operating range.

Key differences between substitutes and the original part:

• Package Configuration: Substitutes use 6-SMD, No Lead packages versus the original 8-SMD, No Lead. PCB layout modifications may be required.
• Maximum Supply Current: Substitutes draw 44mA maximum versus 90mA for the original, representing improved power efficiency.
• Disable Mode Current: Substitutes consume 18mA in disable mode versus 80mA for the original.
• Height: Substitutes are 0.050" (1.28mm) maximum seated height versus 0.059" (1.50mm) for the original, providing reduced board profile.

Both substitutes share identical ECCN (EAR99), HTSUS (8542.39.0001), and MSL (1 - Unlimited) classifications with the original part. Selection between 510LCA100M000BAG and 511LCA100M000BAG depends on specific application requirements and design constraints, as both are electrically and functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can 510LCA100M000BAG and 511LCA100M000BAG be used interchangeably with AX5HCF1-100.0000C?

A: Both Skyworks parts meet all critical electrical and functional parameters: 100 MHz frequency, HCSL output, 1.8V supply, Enable/Disable function, ±20ppm stability, and -40°C to 85°C operating range. However, the package change from 8-SMD to 6-SMD requires PCB layout verification and potential footprint modification.

Q: What are the main differences between the substitute parts and the original?

A: The primary differences are package configuration (6-SMD versus 8-SMD), maximum supply current (44mA versus 90mA), disable mode current (18mA versus 80mA), and seated height (0.050" versus 0.059"). Electrical performance and frequency stability remain identical.

Q: Are there any compliance or certification differences?

A: All three parts share the same ECCN (EAR99), HTSUS code (8542.39.0001), and MSL rating (1 - Unlimited). The original part is ROHS3 compliant; RoHS status for the substitutes is not specified in available documentation.

Q: How do the power consumption differences affect design?

A: The substitute parts consume significantly less current in both active (44mA versus 90mA) and disable modes (18mA versus 80mA). This may reduce thermal load and power supply requirements, potentially simplifying board design.

Q: Is PCB layout modification required for substitution?

A: Yes. The change from 8-SMD to 6-SMD package requires footprint modification. The identical board dimensions (5.00mm x 3.20mm) and reduced height (0.050" versus 0.059") may simplify integration, but the SMD pad configuration differs and must be verified against the substitute part datasheets.
