Substitute Part Grouping Explanation

Substitution of 26 MHz crystal oscillators is determined by strict alignment of the following critical parameters:

Primary Matching Criteria:

• Frequency: 26 MHz (exact match required)
• Frequency Stability: ±20ppm (exact match required)
• Load Capacitance: 8pF (exact match required)
• Operating Mode: Fundamental (exact match required)
• Operating Temperature Range: -20°C ~ 70°C (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)

Secondary Compatibility Parameters:

• Mounting Type: Surface Mount (all substitutes must be surface mount)
• ESR (Equivalent Series Resistance): Variation permitted within 100-200 Ohms range for circuit compatibility
• Physical Dimensions: Variation permitted within SMD footprint tolerance (1.20mm to 2.00mm length; 1.60mm width standard)
• Height - Seated: Variation permitted (0.35mm to 0.55mm maximum)

All substitute parts listed meet the primary matching criteria. ESR and dimensional variations are within acceptable engineering tolerances for direct board-level substitution without circuit redesign.

Engineering Selection Recommendations

All four parts listed—8Y26020002, 416F26022CKR, ABM12-26.000MHZ-B2X-T3, and ECS-260-8-47-JTM-TR—are Active products with full regulatory compliance. Selection between these 26 MHz crystal oscillators should be based on the following engineering considerations:

ESR Compatibility: The 8Y26020002 and ECS-260-8-47-JTM-TR both feature 100 Ohms ESR, providing the lowest impedance option. The 416F26022CKR offers 120 Ohms ESR, representing a minimal 20 Ohm increase. The ABM12-26.000MHZ-B2X-T3 features 200 Ohms ESR, which is the highest among the group but remains within acceptable substitution parameters for most circuit applications.

Physical Footprint: The 8Y26020002 has the largest footprint at 2.00mm x 1.60mm with 0.55mm maximum height. The 416F26022CKR, ABM12-26.000MHZ-B2X-T3, and ECS-260-8-47-JTM-TR all share a compact 1.60mm x 1.20mm footprint with reduced heights (0.45mm, 0.45mm, and 0.35mm respectively). Smaller footprint options are suitable for space-constrained PCB layouts.

Regulatory Compliance: All parts are RoHS Compliant (RoHS3 for CTS, Abracon, and ECS variants), REACH Unaffected, and classified as EAR99 for export control purposes. The 8Y26020002, 416F26022CKR, and ECS-260-8-47-JTM-TR carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related handling restrictions. The ABM12-26.000MHZ-B2X-T3 is listed as Not Applicable for MSL, indicating equivalent or superior moisture performance.

Packaging and Availability: All parts are supplied in Tape & Reel (TR) packaging suitable for automated assembly. Current inventory levels are: 8Y26020002 (1122 Pcs), 416F26022CKR (1448 Pcs), ABM12-26.000MHZ-B2X-T3 (724 Pcs), and ECS-260-8-47-JTM-TR (1756 Pcs).

Frequently Asked Questions (FAQ)

Q: Can the 416F26022CKR substitute for the 8Y26020002 in a production design?

A: Yes. Both parts share identical frequency (26 MHz), frequency stability (±20ppm), load capacitance (8pF), operating mode (Fundamental), temperature range (-20°C ~ 70°C), and package type (4-SMD, No Lead). The ESR difference of 20 Ohms (120 Ohms vs. 100 Ohms) is within acceptable circuit tolerance for most applications. Physical dimensions differ slightly, with the 416F26022CKR being more compact (1.60mm x 1.20mm vs. 2.00mm x 1.60mm).

Q: What is the significance of ESR variation among these crystal oscillators?

A: Equivalent Series Resistance (ESR) affects the crystal's impedance and power consumption in the oscillator circuit. The 8Y26020002 and ECS-260-8-47-JTM-TR both feature 100 Ohms ESR, the lowest among the group. The 416F26022CKR at 120 Ohms and ABM12-26.000MHZ-B2X-T3 at 200 Ohms represent higher impedance options. Higher ESR values may require circuit tuning adjustments in sensitive applications, but all values listed are within standard engineering tolerances for 26 MHz fundamental mode crystals.

Q: Are there physical footprint compatibility concerns when substituting these parts?

A: The 8Y26020002 features a larger footprint (2.00mm x 1.60mm) compared to the other three substitutes (1.60mm x 1.20mm). If the PCB is designed for the larger 8Y26020002 footprint, the smaller alternatives can be used with appropriate pad adjustment or rework. Conversely, if the PCB is designed for the compact 1.60mm x 1.20mm footprint, the 8Y26020002 cannot be directly substituted without PCB redesign. Height variations (0.35mm to 0.55mm) are generally not a concern for standard SMD assembly processes.

Q: Do all substitute parts meet the same regulatory and compliance standards?

A: All four parts are RoHS Compliant, REACH Unaffected, and classified as EAR99 for export control. The 8Y26020002, 416F26022CKR, and ECS-260-8-47-JTM-TR carry Moisture Sensitivity Level 1 (Unlimited). The ABM12-26.000MHZ-B2X-T3 lists MSL as Not Applicable, which indicates equivalent or superior moisture handling characteristics. All parts are suitable for standard manufacturing and storage environments.

Q: Which substitute part offers the best combination of performance and availability?

A: The ECS-260-8-47-JTM-TR offers the lowest ESR (100 Ohms, matching the original 8Y26020002), the smallest height profile (0.35mm), and the highest current inventory (1756 Pcs). The 416F26022CKR provides a balanced option with slightly higher ESR (120 Ohms) and strong availability (1448 Pcs). Selection should be based on specific circuit requirements, PCB layout constraints, and delivery timeline needs.

Q: Can these 26 MHz crystals be used interchangeably in different circuit topologies?

A: All four parts operate in Fundamental mode across the identical temperature range (-20°C ~ 70°C) with matching frequency stability (±20ppm) and load capacitance (8pF). However, circuit-specific factors such as oscillator design, load impedance, and tuning capacitance may influence performance. ESR variations (100-200 Ohms) could affect startup behavior or power consumption in certain topologies. Engineering validation is recommended for critical applications, though all parts are designed for standard 26 MHz oscillator circuits.
