Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7M26000028 is determined by strict alignment of electrical and mechanical parameters. The primary substitution criteria are:

Critical Parameters (Must Match):

• Frequency: 26 MHz
• Frequency Stability: ±10ppm
• Frequency Tolerance: ±10ppm
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, No Lead
• Operating Temperature Range: -20°C ~ 75°C

Secondary Parameters (Allowable Variation):

• Load Capacitance: 7.5pF (main part) to 9pF (substitute parts) — acceptable variation within crystal oscillator design margins
• Load Capacitance: 7.5pF (main part) to 8pF (substitute parts) — acceptable variation within crystal oscillator design margins
• ESR (Equivalent Series Resistance): Not specified in main part; 60 Ohms in substitute parts — acceptable specification
• Physical Dimensions: Variation permitted within 4-SMD, No Lead package class

All substitute parts listed maintain identical frequency, stability, tolerance, temperature range, and mounting specifications. Load capacitance variations of ±1.5pF are within acceptable engineering tolerances for 26 MHz crystal applications.

Frequently Asked Questions (FAQ)

Q: Can the EPSON FA-128 26.0000MF10Z-AC3 directly replace the TXC 7M26000028?

A: Yes. Both parts share identical frequency (26 MHz), frequency stability (±10ppm), operating temperature range (-20°C to 75°C), mounting type (Surface Mount), and package specification (4-SMD, No Lead). The load capacitance difference (9pF vs 7.5pF) is within acceptable engineering tolerances for 26 MHz crystal applications.

Q: What is the significance of load capacitance variation between the main part and substitutes?

A: Load capacitance affects the crystal's resonant frequency in the circuit. The 7.5pF specification of the 7M26000028 and the 8pF to 9pF specifications of substitute parts represent acceptable variations within crystal oscillator design margins. Circuit designers typically account for ±1.5pF load capacitance tolerance in frequency-critical applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. The EPSON and Diodes Incorporated parts carry ROHS3 Compliant certification. The NDK America part carries RoHS Compliant certification. All parts meet regulatory requirements for RoHS compliance.

Q: What packaging options are available for the substitute parts?

A: FA-128 26.0000MF10Z-AC3 is supplied in Tape & Reel (TR) format. FA-20H 26.0000MF10Z-AC3 is supplied in Cut Tape (CT) & Digi-Reel® format. FW2600018 and STDCSX1-26M are supplied in Tape & Reel (TR) format. Selection depends on assembly process requirements and volume needs.

Q: Which substitute part has the closest load capacitance match to the 7M26000028?

A: The NDK America STDCSX1-26M offers 8pF load capacitance, representing a 0.5pF difference from the 7.5pF specification. The EPSON and Diodes parts offer 9pF, representing a 1.5pF difference. Both variations are within acceptable tolerances.

Q: Do all parts maintain the same operating temperature range?

A: Yes. All substitute parts operate across the identical -20°C to 75°C temperature range as the 7M26000028, ensuring thermal compatibility in equivalent applications.

Q: What is the moisture sensitivity level for these crystal parts?

A: All parts, including the main part and all substitutes, carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.
