402F26033CLR 26 MHz Crystal Equivalent & Substitute Parts

Part Overview

The 402F26033CLR is a 26 MHz surface mount crystal manufactured by CTS-Frequency Controls. This fundamental mode crystal operates at ±30ppm frequency stability with a 12pF load capacitance and 100 Ohms equivalent series resistance. The component is housed in a 4-SMD, No Lead package measuring 2.00mm × 1.60mm with a maximum seated height of 0.55mm. The part is Active status and RoHS3 compliant, making it suitable for modern electronic applications requiring precise frequency reference. Alternative equivalent parts may be required due to inventory availability, supply chain considerations, or design flexibility across manufacturing sources.

Substitute Part Grouping Explanation

Substitution of the 402F26033CLR is determined by strict equivalence across the following critical parameters: frequency (26 MHz), frequency stability (±30ppm), load capacitance (12pF), ESR (100 Ohms), operating mode (Fundamental), operating temperature range (-20°C to 70°C), mounting type (Surface Mount), and package configuration (4-SMD, No Lead). All substitute parts listed maintain identical electrical specifications and are housed in compatible SMD packages. Physical dimensions may vary within acceptable tolerances for PCB footprint compatibility. Compliance certifications (RoHS, REACH, MSL) are verified for each substitute to ensure regulatory alignment.

Parameter Comparison

Engineering Selection Recommendations

All three parts—402F26033CLR, 8Z-26.000MAAE-T, and 8Y-26.000MAAE-T—are Active status components with full regulatory compliance. The 402F26033CLR and 8Y-26.000MAAE-T share identical physical dimensions (2.00mm × 1.60mm), making them direct footprint-compatible substitutes. The 8Z-26.000MAAE-T features slightly larger dimensions (2.50mm × 2.00mm) while maintaining the same electrical specifications and maximum seated height. Selection between these parts should be based on PCB layout constraints, inventory availability, and supply chain requirements. All parts maintain equivalent electrical performance across the specified operating temperature range and load conditions.

Frequently Asked Questions (FAQ)

Q: Can the 8Z-26.000MAAE-T be used as a direct replacement for the 402F26033CLR?

A: The 8Z-26.000MAAE-T is electrically equivalent but has different physical dimensions (2.50mm × 2.00mm versus 2.00mm × 1.60mm). PCB footprint compatibility must be verified before substitution.

Q: Are the 8Y-26.000MAAE-T and 402F26033CLR interchangeable?

A: Yes. Both parts share identical electrical specifications, operating temperature range, and physical dimensions (2.00mm × 1.60mm), making them direct substitutes.

Q: What are the critical parameters for crystal substitution?

A: Frequency (26 MHz), frequency stability (±30ppm), load capacitance (12pF), ESR (100 Ohms), operating mode (Fundamental), and package configuration (4-SMD, No Lead) must remain constant for functional equivalence.

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

A: All listed parts are RoHS compliant, REACH unaffected, and carry MSL 1 (Unlimited) ratings. The 402F26033CLR is RoHS3 compliant, while the TXC parts are RoHS compliant.

Q: What is the maximum seated height for these crystals?

A: All three parts have a maximum seated height of 0.55mm, ensuring compatibility with standard PCB assembly processes.
