AB-16.000MAME-T Equivalent & Substitute Parts

Part Overview

The AB-16.000MAME-T is a 16 MHz fundamental mode crystal oscillator manufactured by TXC CORPORATION. This surface mount device is specified for 12pF load capacitance with 80 Ohms equivalent series resistance (ESR) and operates across the industrial temperature range of -40°C to 125°C. The part maintains AEC-Q200 automotive qualification and RoHS compliance. Substitute parts are identified to address inventory availability, packaging format preferences, or supply chain requirements while maintaining electrical and mechanical compatibility within specified tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AB-16.000MAME-T is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Frequency: 16.0000 MHz (exact match required)
• Load Capacitance: 12 pF (exact match required)
• Frequency Tolerance: ±30 ppm (substitute must meet or exceed this specification)
• Operating Temperature Range: -40°C to 125°C (substitute must cover this range)
• Package Type: 4-SMD, No Lead (physical footprint compatibility)
• Mounting Type: Surface Mount (assembly process compatibility)

Acceptable Variation Parameters:

• ESR (Equivalent Series Resistance): Substitute ESR values within ±25% of the main part specification are acceptable, provided circuit design margins accommodate the variation
• Packaging Format: Tape & Reel (TR) and Cut Tape (CT) formats are interchangeable for the same component
• Moisture Sensitivity Level (MSL): Both MSL 1 ratings are equivalent

Compliance Parameters:

• AEC-Q200 automotive qualification required for automotive applications
• RoHS compliance required for regulatory adherence

Engineering Selection Recommendations

Primary Selection (AB-16.000MAME-T): The AB-16.000MAME-T remains the primary choice when TXC CORPORATION supply is available. This part carries active product status, AEC-Q200 automotive qualification, and RoHS compliance. Inventory of 769 pieces supports immediate deployment.

Substitute Selection (FC3BACAGI16.0-T3): The FC3BACAGI16.0-T3 from Fox Electronics qualifies as an equivalent substitute based on matching critical electrical parameters: 16 MHz frequency, ±30 ppm tolerance, 12 pF load capacitance, and identical operating temperature range. Both parts maintain AEC-Q200 automotive qualification and current RoHS3 compliance.

Key Differences Affecting Selection:

1. ESR Variation: The substitute exhibits 100 Ohms ESR compared to 80 Ohms in the main part. This 25% increase falls within acceptable variation for most circuit designs. Circuit designers must verify that oscillator startup margin and frequency stability remain within specification with the higher ESR value.

2. Physical Dimensions: The FC3BACAGI16.0-T3 features a smaller footprint (3.20mm x 2.50mm versus 5.00mm x 3.20mm) and lower profile (0.80mm versus 1.05mm). This dimensional reduction is compatible with PCB layouts designed for the larger main part, as the substitute occupies less board space.

3. Packaging Format: The main part is supplied in Tape & Reel (TR) format; the substitute is supplied in Cut Tape (CT) format. Both formats are suitable for automated assembly processes.

4. Inventory Availability: The substitute maintains higher inventory (1,055 pieces) compared to the main part (769 pieces), supporting extended supply chain requirements.

Compliance Verification: Both parts satisfy AEC-Q200 automotive qualification and RoHS compliance requirements. The substitute carries REACH Unaffected status, providing additional regulatory clarity for European applications.

Frequently Asked Questions (FAQ)

Q1: Can the FC3BACAGI16.0-T3 be used as a direct replacement for the AB-16.000MAME-T in all applications?

A: The FC3BACAGI16.0-T3 qualifies as an electrical and mechanical equivalent for applications where the 100 Ohms ESR specification is acceptable. Circuit designers must confirm that oscillator startup behavior and frequency stability margins remain within design specifications with the higher ESR value. Both parts share identical frequency, load capacitance, temperature range, and AEC-Q200 qualification.

Q2: What is the significance of the ESR difference between these parts?

A: ESR (Equivalent Series Resistance) affects crystal oscillator startup time and frequency stability. The substitute's 100 Ohms ESR represents a 25% increase over the main part's 80 Ohms specification. This variation is within acceptable engineering tolerance for most applications but must be verified during circuit design validation, particularly for low-power or battery-operated designs where startup margin is critical.

Q3: Are the physical dimension differences between these parts compatible with existing PCB layouts?

A: Yes. The FC3BACAGI16.0-T3 features a smaller footprint (3.20mm x 2.50mm) and lower profile (0.80mm) compared to the AB-16.000MAME-T (5.00mm x 3.20mm, 1.05mm height). PCB layouts designed for the larger main part will accommodate the smaller substitute without modification. However, layouts designed specifically for the smaller substitute cannot accommodate the larger main part.

Q4: What is the difference between Tape & Reel and Cut Tape packaging formats?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) packaging supplies components on cut segments of carrier tape, suitable for lower-volume or mixed-component assembly processes. Both formats are compatible with standard pick-and-place assembly equipment.

Q5: Do both parts meet automotive qualification requirements?

A: Yes. Both the AB-16.000MAME-T and FC3BACAGI16.0-T3 carry AEC-Q200 automotive qualification, confirming compliance with automotive industry reliability and quality standards. Both parts are suitable for automotive applications requiring this certification.

Q6: What is the difference between RoHS and ROHS3 compliance?

A: RoHS (Restriction of Hazardous Substances) compliance restricts the use of specified hazardous materials in electrical and electronic equipment. ROHS3 represents the current version of the RoHS directive. Both designations indicate compliance with hazardous substance restrictions; ROHS3 reflects the current regulatory standard. Both parts satisfy RoHS compliance requirements.

Q7: Can these parts be used interchangeably in the same production batch?

A: Interchangeability depends on circuit design validation. Both parts meet identical electrical specifications for frequency, tolerance, load capacitance, and temperature range. However, the ESR difference must be evaluated during design validation to confirm that oscillator performance remains within specification. Once validated, both parts can be used interchangeably, provided supply chain documentation clearly identifies which part is installed in each unit.

Q8: What factors should determine the choice between these two parts?

A: Selection should be based on: (1) Supply availability and lead time requirements; (2) Packaging format compatibility with assembly processes; (3) Circuit design validation confirming acceptable performance with 100 Ohms ESR; (4) Cost considerations if applicable; (5) Inventory management and supply chain strategy. Both parts satisfy all critical electrical and compliance requirements.
