FN2500258Z Equivalent & Substitute Parts

Part Overview

The FN2500258Z is a 25 MHz XO (Standard) LVCMOS oscillator manufactured by Diodes Incorporated, part of the SaRonix-eCera™ FN series. This crystal oscillator operates at 3.3V with enable/disable functionality and is housed in a 4-SMD, No Lead package. The device is Active status and ROHS3 compliant. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are required for design flexibility, inventory management, or supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FN2500258Z is based on strict equivalence of the following critical parameters:

• Frequency: 25 MHz
• Output: LVCMOS
• Supply Voltage: 3.3V
• Function: Enable/Disable
• Frequency Stability: ±50ppm
• Operating Temperature: -20°C ~ 70°C
• Package / Case: 4-SMD, No Lead
• Footprint Dimensions: 7.00mm x 5.00mm
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The CWX823-025.0M from Connor Winfield meets all these critical electrical and mechanical parameters, making it a direct substitute for the FN2500258Z.

Parameter Comparison

*Compatible: CWX823-025.0M has higher maximum supply current (30mA vs 10mA) and lower seated height (1.30mm vs 1.80mm), both acceptable for substitution in applications designed for FN2500258Z.

Engineering Selection Recommendations

Both FN2500258Z and CWX823-025.0M are Active status products with ROHS3 compliance and REACH Unaffected status. Selection between these parts is based on:

• Availability: CWX823-025.0M has higher inventory (17,093 pcs vs 791 pcs)
• Supply current tolerance: Applications requiring lower maximum current draw should specify FN2500258Z; applications with higher current tolerance can use CWX823-025.0M
• PCB height constraints: CWX823-025.0M offers lower profile (1.30mm vs 1.80mm) for space-constrained designs
• Regulatory compliance: Both parts meet identical compliance requirements (ROHS3, REACH Unaffected, EAR99, HTSUS 8542.39.0001)

Frequently Asked Questions (FAQ)

Q: Can CWX823-025.0M replace FN2500258Z in existing designs?

A: Yes. Both parts share identical electrical specifications (25 MHz, LVCMOS, 3.3V, ±50ppm stability, -20°C ~ 70°C operation) and mechanical compatibility (4-SMD, No Lead, 7.00mm x 5.00mm footprint). The CWX823-025.0M has higher maximum supply current (30mA vs 10mA) and lower seated height (1.30mm vs 1.80mm), both acceptable for direct substitution.

Q: Are there any pin compatibility concerns?

A: No. Both parts use identical 4-SMD, No Lead packaging with the same footprint dimensions (7.00mm x 5.00mm). PCB layout and schematic connections remain unchanged.

Q: What is the difference in supply current specifications?

A: FN2500258Z specifies 10mA maximum supply current; CWX823-025.0M specifies 30mA maximum. The CWX823-025.0M can be used in applications designed for FN2500258Z without modification, as it operates within the same voltage and frequency parameters.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both FN2500258Z and CWX823-025.0M are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are there compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH Unaffected, and classified under identical ECCN (EAR99) and HTSUS (8542.39.0001) codes.
