Key Parameters

Substitute Part Grouping Explanation

Substitution for the CS09818-26M is determined by strict alignment of electrical and mechanical parameters. The primary substitution criteria are:

Critical Parameters for Substitution:

• Frequency: 26 MHz (exact match required)
• Operating Mode: Fundamental
• Package / Case: 4-SMD, No Lead
• Size / Dimension: 2.00mm x 1.60mm
• Height - Seated (Max): 0.50mm
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C to 125°C
• RoHS Status: ROHS3 Compliant
• Ratings: AEC-Q200

Electrical Parameters Allowing Variation:

• Load Capacitance: 10pF (primary) or 8pF (acceptable substitute)
• ESR: 60 Ohms (consistent across all parts)

The CS07225-26M is classified as a Similar Manufacturer Part with a 2pF load capacitance difference (8pF vs. 10pF). The CS08144-26M is classified as a Parametric Equivalent with identical electrical specifications to the main part.

Parameter Comparison

Engineering Selection Recommendations

CS08144-26M (Parametric Equivalent): This part is a direct parametric equivalent to the CS09818-26M, sharing identical electrical and mechanical specifications including 10pF load capacitance and 60 Ohms ESR. Both parts maintain Active product status, ROHS3 compliance, and AEC-Q200 certification. Selection between these two parts is based on inventory availability and supply chain considerations, as no functional differentiation exists.

CS07225-26M (Similar Manufacturer Part): This part differs from the main part by load capacitance specification (8pF versus 10pF). All other parameters remain aligned: 26 MHz frequency, 60 Ohms ESR, identical package dimensions, surface mount configuration, operating temperature range, ROHS3 compliance, and AEC-Q200 certification. The load capacitance variation must be evaluated against circuit design requirements and oscillator tuning specifications.

All three parts are manufactured by NDK America, Inc., belong to the NX2016SA series, maintain Active product status, and satisfy automotive-grade reliability standards through AEC-Q200 certification.

Frequently Asked Questions (FAQ)

Q: Can CS08144-26M be used as a direct replacement for CS09818-26M?
