Key Parameters

Substitute Part Grouping Explanation

Substitution of the CS00469-26M is determined by strict alignment of the following critical parameters: frequency (26 MHz), frequency tolerance (±10ppm), load capacitance (10pF), package type (4-SMD, No Lead), physical dimensions (3.20mm x 2.50mm), and operating mode (Fundamental). All substitute parts listed maintain these core electrical and mechanical specifications. ESR values may vary within acceptable ranges for crystal oscillators of this class. Operating temperature ranges may differ; selection should account for application-specific thermal requirements. All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance. CS00468-26M and CS00546-26M are direct NDK America alternatives with identical electrical specifications to the main part, differing only in operating temperature upper limit (70°C versus 75°C). Both parts offer significantly higher inventory availability. ECS-260-10-33B-CKM-TR from ECS Inc. provides equivalent functionality with a lower ESR value (40 Ohms versus 50 Ohms) and slightly increased maximum height (0.80mm versus 0.70mm). ABM8-26.000MHZ-10-1-U-T from Abracon LLC matches the main part's ESR specification but operates within a narrower temperature range (-10°C to 60°C). Selection should prioritize application temperature requirements and ESR performance characteristics specific to circuit design parameters.

Frequently Asked Questions (FAQ)

Q: Can CS00468-26M replace CS00469-26M in all applications? A: CS00468-26M is electrically equivalent with identical frequency, tolerance, load capacitance, and ESR specifications. The operating temperature range differs by 5°C at the upper limit (70°C versus 75°C). Substitution is valid for applications operating within -20°C to 70°C.

Q: What is the significance of ESR differences between substitute parts? A: ESR (Equivalent Series Resistance) affects circuit startup characteristics and power consumption. The main part and most substitutes specify 50 Ohms ESR. ECS-260-10-33B-CKM-TR specifies 40 Ohms ESR, which may improve startup performance in some circuit topologies but requires verification against circuit design specifications.

Q: Are all substitute parts compatible with the same PCB footprint? A: All substitute parts share identical package type (4-SMD, No Lead) and base dimensions (3.20mm x 2.50mm). Maximum seated height varies slightly: CS00469-26M, CS00468-26M, and CS00546-26M are 0.70mm; ECS-260-10-33B-CKM-TR and ABM8-26.000MHZ-10-1-U-T are 0.80mm. Verify PCB clearance specifications for applications with height constraints.

Q: Which substitute part offers the best inventory availability? A: CS00468-26M provides the highest inventory level at 43,394 pieces, followed by CS00546-26M at 30,696 pieces. Both are NDK America products with specifications matching the main part within the stated temperature range.

Q: Do all substitute parts meet the same compliance standards? A: All listed parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols. ECS Inc. and Abracon LLC parts additionally carry REACH Unaffected status.
