AS-13.560MAHE-B Equivalent & Substitute Parts

Part Overview

The AS-13.560MAHE-B is a 13.56 MHz through-hole crystal oscillator manufactured by TXC CORPORATION, designed for fundamental mode operation with 12pF load capacitance and 60 Ohms equivalent series resistance. This component operates across the -40°C to 85°C temperature range with ±30ppm frequency stability and is housed in the HC-49/US package format.

The AS-13.560MAHE-B is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support legacy system maintenance where this crystal frequency and electrical specification remain functionally required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AS-13.560MAHE-B is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 13.56 MHz (exact match required)
• Load Capacitance: 12pF (exact match required)
• Operating Mode: Fundamental (exact match required)

Allowable Variation Parameters:

• Frequency Stability: ±30ppm or tighter (lower values acceptable)
• Frequency Tolerance: ±30ppm or tighter (lower values acceptable)
• ESR: Variations permitted within circuit design margins
• Operating Temperature Range: Must encompass or match the required range
• Mounting Type: Through-hole preferred for direct replacement; surface-mount variants require PCB redesign
• Package Format: HC-49/US preferred for direct replacement; alternative packages require mechanical redesign

Compliance Considerations:

• RoHS Status: Compliant or ROHS3 Compliant acceptable
• AEC-Q200 Rating: Preferred for automotive and high-reliability applications
• Product Status: Active preferred; obsolete acceptable for legacy support

Two substitute parts meet these criteria with documented electrical and mechanical compatibility.

Engineering Selection Recommendations

9B-13.560MAAE-B (Through-Hole Substitute):

This part provides direct mechanical compatibility with the AS-13.560MAHE-B, sharing the HC-49/US through-hole package format and identical frequency/load capacitance specifications. The 9B-13.560MAAE-B features lower ESR (40 Ohms versus 60 Ohms), which reduces power consumption and improves oscillator startup characteristics. However, the operating temperature range is narrower (-20°C ~ 70°C versus -40°C ~ 85°C), restricting use in applications requiring full military or extended temperature operation. This part is ROHS3 compliant and REACH affected. Selection of this substitute is appropriate for legacy through-hole PCB designs operating within the -20°C to 70°C temperature envelope.

AM-13.560MDHE-T (Surface-Mount Substitute):

This part maintains identical frequency, load capacitance, and operating temperature range (-40°C ~ 85°C) as the main part, with tighter frequency tolerance (±20ppm versus ±30ppm). The AM-13.560MDHE-T is surface-mount (4-SMD, No Lead package), requiring PCB redesign and reflow soldering processes. Higher ESR (100 Ohms versus 60 Ohms) increases power consumption and may affect oscillator startup margin in designs with weak drive capability. This part carries AEC-Q200 rating and active product status, ensuring long-term availability and supply chain support. Selection of this substitute is appropriate for new designs or redesigned PCBs where surface-mount assembly is preferred and the higher ESR is accommodated by circuit design.

Frequently Asked Questions (FAQ)

Q: Can the 9B-13.560MAAE-B directly replace the AS-13.560MAHE-B in all applications?

A: Direct mechanical and electrical replacement is possible for applications operating within the -20°C to 70°C temperature range. Applications requiring operation below -20°C or above 70°C must use the AM-13.560MDHE-T or retain the original AS-13.560MAHE-B. The lower ESR of the 9B-13.560MAAE-B (40 Ohms) is electrically compatible and improves performance in most oscillator circuits.

Q: What are the implications of the AM-13.560MDHE-T's higher ESR (100 Ohms)?

A: Higher ESR increases power dissipation in the crystal element and may reduce oscillator startup margin in circuits with weak drive capability. Circuit designers must verify that the oscillator amplifier provides sufficient drive current to sustain oscillation with 100 Ohms ESR. Existing through-hole designs cannot accommodate this part without PCB redesign.

Q: Is the AM-13.560MDHE-T suitable for automotive applications?

A: Yes. The AM-13.560MDHE-T carries AEC-Q200 qualification, indicating suitability for automotive-grade reliability requirements. The AS-13.560MAHE-B also carries AEC-Q200 rating. The 9B-13.560MAAE-B does not carry AEC-Q200 rating.

Q: Why does the 9B-13.560MAAE-B have a narrower operating temperature range?

A: The 9B-13.560MAAE-B is specified for -20°C ~ 70°C operation. This narrower range reflects the design and qualification limits of this particular series. Applications requiring -40°C operation must select the AS-13.560MAHE-B or AM-13.560MDHE-T.

Q: Can the AM-13.560MDHE-T be used in existing through-hole PCB designs?

A: No. The AM-13.560MDHE-T uses a 4-SMD, No Lead surface-mount package, incompatible with through-hole PCB footprints. PCB redesign and reflow soldering capability are required. For through-hole designs, the 9B-13.560MAAE-B is the appropriate substitute.

Q: What is the significance of the tighter frequency tolerance (±20ppm) in the AM-13.560MDHE-T?

A: The ±20ppm tolerance in the AM-13.560MDHE-T is tighter than the ±30ppm specification of the main part, providing improved frequency accuracy. This is a performance enhancement and does not restrict substitution compatibility. Circuits designed for ±30ppm tolerance operate within specification with ±20ppm parts.

Q: Are there supply chain advantages to selecting the AM-13.560MDHE-T?

A: Yes. The AM-13.560MDHE-T carries active product status, indicating ongoing manufacturing and distribution support. The AS-13.560MAHE-B and 9B-13.560MAAE-B are both obsolete, with limited inventory availability. For new designs or long-term production, the AM-13.560MDHE-T provides superior supply chain continuity.
