SCAN921025HSM Equivalent & Substitute Parts

Part Overview

The SCAN921025HSM is a high-temperature serializer interface IC manufactured by Texas Instruments, designed for 800Mbps data rate conversion from LVCMOS/LVTTL inputs to LVDS outputs. This component is classified as not for new designs, indicating it has been superseded in the product lifecycle. Finding equivalent substitute parts is necessary for legacy system maintenance, repair operations, and inventory management where the original part number may be unavailable or where active product variants are preferred for new procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCAN921025HSM is determined by strict equivalence across the following critical parameters: identical serializer function, 800Mbps data rate capability, 10 LVCMOS/LVTTL inputs to 1 LVDS output configuration, 3V to 3.6V supply voltage range, -40°C to 125°C operating temperature range, 49-LFBGA (7x7) package type, and surface mount mounting technology. The substitute part SCAN921025HSM/NOPB meets all these electrical and mechanical requirements, differing only in product lifecycle status and moisture sensitivity classification, which do not affect functional compatibility in equivalent circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The SCAN921025HSM/NOPB is the direct functional equivalent of SCAN921025HSM. Both parts share identical electrical specifications and package geometry, ensuring pin-for-pin compatibility and equivalent circuit performance. The primary distinction is product lifecycle status: SCAN921025HSM/NOPB carries Active status, making it the preferred selection for new procurement and long-term supply chain continuity. The SCAN921025HSM/NOPB also carries REACH Unaffected certification, providing regulatory advantage in restricted substance compliance. The moisture sensitivity level difference (MSL 3 versus MSL 4) reflects storage and handling requirements but does not affect functional equivalence in installed applications. For legacy system repairs or replacement scenarios where SCAN921025HSM inventory is depleted, SCAN921025HSM/NOPB provides direct substitution without circuit redesign or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can SCAN921025HSM/NOPB be used as a direct replacement for SCAN921025HSM in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all functional parameters: 800Mbps serializer operation, 10 LVCMOS/LVTTL inputs, 1 LVDS output, 3V to 3.6V supply voltage, -40°C to 125°C operating temperature, and 49-LFBGA (7x7) package. Pin-for-pin compatibility is guaranteed.

Q: What is the significance of the product status difference between these parts?

A: SCAN921025HSM is marked Not For New Designs, indicating it has been superseded in Texas Instruments' product portfolio. SCAN921025HSM/NOPB carries Active status, ensuring ongoing manufacturing support, documented availability, and long-term supply chain reliability for new procurement.

Q: Does the moisture sensitivity level difference affect substitution suitability?

A: Moisture sensitivity level (MSL) classification affects storage, handling, and shelf-life requirements prior to assembly, not functional performance after installation. SCAN921025HSM/NOPB with MSL 4 (72 hours) requires more controlled storage conditions than SCAN921025HSM with MSL 3 (168 hours), but both parts perform identically once soldered into the circuit.

Q: Are there any regulatory compliance differences between these parts?

A: SCAN921025HSM/NOPB carries REACH Unaffected certification, while SCAN921025HSM is REACH Affected. Both are ROHS3 Compliant. For applications subject to REACH regulations, SCAN921025HSM/NOPB provides regulatory advantage. Both parts share identical ECCN and HTSUS classifications.

Q: What packaging formats are available for these serializer parts?

A: Both SCAN921025HSM and SCAN921025HSM/NOPB are supplied in 49-NFBGA (7x7) package format with surface mount mounting type. No alternative package options are available for these part numbers.
