Q: What is the significance of the seated height variation?

A: Seated heights range from 1.42mm (original 7W-25.000MBD-T) to 1.90mm (Cardinal Components parts). These variations are within acceptable tolerances for standard PCB assembly and do not affect electrical performance or mechanical fit in typical applications. Verify clearance in your specific PCB layout if height-constrained applications are involved.

Q: Do all substitute parts have the same frequency stability specification?

A: Yes. All substitute parts, including the original 7W-25.000MBD-T, specify ±25ppm frequency stability across the -40°C to 85°C operating temperature range. This ensures consistent timing accuracy across all alternatives.

Q: Which substitute part has the highest inventory availability?

A: The SXO75C3C481-25.000M from Suntsu Electronics has the highest inventory level at 12,029 pieces. The OCETDLJANF-25.000000 from Taitien has the second-highest availability at 3,414 pieces.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts carry RoHS compliance certifications (either RoHS3 or equivalent RoHS status). The original 7W-25.000MBD-T is also RoHS Compliant. All parts are REACH Unaffected and classified under ECCN EAR99.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All parts, including the original 7W-25.000MBD-T, carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity concerns during storage and handling.
