Substitute Part Grouping Explanation

Substitution for the FA2016AN 26.0000MF10P-KB is determined by the following critical parameters:

Frequency: Must be 26 MHz
Operating Mode: Must be Fundamental
Package / Case: Must be 4-SMD, No Lead
Physical Dimensions: Must match 0.079" L x 0.063" W (2.00mm x 1.60mm)
ESR: Must be 60 Ohms
Mounting Type: Must be Surface Mount

The substitute parts identified maintain these core electrical and mechanical specifications. Variations in load capacitance (10pF vs. 12pF) and operating temperature range are permitted within the allowed parameter tolerance for this product category, provided the primary frequency, package, and ESR specifications remain constant.

Engineering Selection Recommendations

EPSON FA-128 26.0000MF10Z-W: This substitute maintains identical frequency, ESR, operating temperature range, and package specifications as the main part. The load capacitance difference (12pF vs. 10pF) falls within acceptable substitution parameters. The part is active in production with ROHS3 compliance and unlimited moisture sensitivity rating. This is the preferred substitute for direct replacement in existing designs.

NDK America CS09818-26M: This substitute matches the frequency, load capacitance, ESR, package, and physical dimensions of the main part. The extended operating temperature range (-40°C ~ 125°C) provides broader environmental capability. The part carries AEC-Q200 automotive qualification and is active in production. This substitute is suitable for applications requiring extended temperature performance or automotive-grade reliability.

Frequently Asked Questions (FAQ)

Q: Can the FA-128 26.0000MF10Z-W be used as a direct replacement for the FA2016AN 26.0000MF10P-KB?

A: Yes. Both parts share identical frequency (26 MHz), ESR (60 Ohms), operating temperature range (-20°C ~ 75°C), and package specifications (4-SMD, no lead, 2.00mm x 1.60mm). The load capacitance difference (12pF vs. 10pF) is within acceptable substitution tolerance for this crystal category.

Q: What is the difference between the two substitute parts?

A: The EPSON FA-128 maintains the closest electrical and thermal specifications to the original part. The NDK America CS09818-26M offers an extended operating temperature range (-40°C ~ 125°C) and AEC-Q200 automotive qualification, making it suitable for more demanding environmental applications.

Q: Are all three parts physically interchangeable?

A: Yes. All three parts share identical package specifications (4-SMD, no lead), physical dimensions (0.079" L x 0.063" W / 2.00mm x 1.60mm), and maximum seated height (0.020" / 0.50mm). They are mechanically interchangeable in PCB layouts designed for this form factor.

Q: Does load capacitance affect substitution compatibility?

A: Load capacitance affects circuit tuning and frequency accuracy. The FA-128 operates at 12pF load capacitance compared to the original 10pF specification. Circuit design must accommodate this difference through appropriate load network adjustment to maintain target frequency performance.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity), meeting current environmental and regulatory requirements.
