FH2400032Z 24 MHz Crystal Equivalent & Substitute Parts

Part Overview

The FH2400032Z is a 24 MHz fundamental mode crystal manufactured by Diodes Incorporated in the SaRonix-eCera™ FH series. This surface mount crystal operates at ±30ppm frequency stability with a 10pF load capacitance and 50 Ohms equivalent series resistance (ESR). The component is packaged in a 4-SMD, No Lead configuration measuring 2.50mm × 2.00mm with a maximum seated height of 0.70mm. The part maintains Active product status and is RoHS3 compliant with MSL 1 rating. Substitute parts are identified for applications requiring alternative electrical characteristics or packaging configurations while maintaining the core 24 MHz frequency specification.

Substitute Part Grouping Explanation

Substitution eligibility for the FH2400032Z is determined by the following critical parameters: frequency (24 MHz), frequency stability (±30ppm), operating mode (Fundamental), operating temperature range (-20°C to 70°C), mounting type (Surface Mount), package type (4-SMD, No Lead), and compliance certifications (RoHS, MSL 1).

The identified substitute parts maintain identical frequency, frequency stability, operating mode, temperature range, mounting type, and package classification. Variations occur in load capacitance (8pF to 12pF range) and ESR (50 to 150 Ohms range). These electrical parameter variations are within acceptable substitution tolerances for 24 MHz crystal applications, provided the circuit design accommodates the alternative load capacitance and ESR values.

All substitute parts are Active status components with RoHS compliance and MSL 1 ratings, ensuring regulatory and environmental compatibility with the original specification.

Engineering Selection Recommendations

All identified substitute parts maintain Active product status and RoHS compliance, ensuring regulatory alignment with the FH2400032Z. Selection between substitute options depends on circuit-specific load capacitance requirements and physical space constraints.

For applications requiring 10pF load capacitance matching the original specification, 8Z-24.000MAAE-T provides the closest electrical alignment with 12pF load capacitance and identical 2.50mm × 2.00mm footprint dimensions.

For applications tolerating 8pF load capacitance, 8Y-24.000MAAV-T and 8Z-24.000MAAV-T offer equivalent ESR (100 Ohms) with the same 2.50mm × 2.00mm footprint. The 8Q-24.000MAAV-T provides the most compact form factor (1.60mm × 1.20mm) with 8pF load capacitance and 100 Ohms ESR for space-constrained designs.

The 7R-24.000MAAV-T offers a smaller footprint (2.05mm × 1.65mm) but features elevated ESR (150 Ohms), requiring circuit design confirmation for compatibility.

All substitute parts carry MSL 1 ratings and operate across the -20°C to 70°C temperature range, maintaining environmental specification parity with the original component.

Frequently Asked Questions (FAQ)

Q: Can 8pF load capacitance crystals substitute for the 10pF FH2400032Z?

A: Substitution is possible when circuit design accommodates 8pF load capacitance. The oscillator circuit must be designed or adjusted to function with the lower capacitance value. Load capacitance mismatch affects oscillation frequency and startup characteristics.

Q: What is the impact of ESR variation between substitute parts?

A: ESR affects oscillator startup time and power consumption. The FH2400032Z operates at 50 Ohms ESR. Substitute parts range from 100 to 150 Ohms ESR. Higher ESR values increase startup time and power draw but do not affect steady-state frequency accuracy when frequency stability is maintained at ±30ppm.

Q: Are all substitute parts compatible with the same PCB footprint?

A: No. While all parts use 4-SMD, No Lead packaging, physical dimensions vary. The FH2400032Z and 8Z-24.000MAAE-T/8Z-24.000MAAV-T share identical 2.50mm × 2.00mm footprints. The 8Y-24.000MAAV-T measures 2.00mm × 1.60mm, 7R-24.000MAAV-T measures 2.05mm × 1.65mm, and 8Q-24.000MAAV-T measures 1.60mm × 1.20mm. PCB land pattern compatibility must be confirmed before substitution.

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

A: All substitute parts are RoHS compliant and carry MSL 1 ratings. The FH2400032Z is RoHS3 compliant, while substitute parts are RoHS compliant. Both certifications meet current regulatory requirements. REACH status varies by manufacturer; specific REACH documentation is available upon request for FTS components.

Q: Which substitute part provides the closest electrical match to FH2400032Z?

A: The 8Z-24.000MAAE-T provides the closest match with 12pF load capacitance (versus 10pF), 100 Ohms ESR (versus 50 Ohms), and identical 2.50mm × 2.00mm physical dimensions. This minimizes circuit redesign requirements.
