Engineering Selection Recommendations

Both FH52-28S-0.5SH and FH52-28S-0.5SH(99) are active production parts from Hirose Electric Co Ltd with full RoHS compliance. The FH52-28S-0.5SH(99) carries ROHS3 certification and REACH unaffected status, providing enhanced regulatory documentation for applications requiring advanced compliance tracking. Selection between these parts should be based on inventory availability and specific regulatory documentation requirements for the end application. Both parts are electrically and mechanically interchangeable for 28-position, 0.5mm pitch FFC/FPC connector applications with surface mount right-angle configuration.

Frequently Asked Questions (FAQ)

Q: Can FH52-28S-0.5SH(99) be used as a direct replacement for FH52-28S-0.5SH?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (28 positions, 0.5mm pitch, 0.5A rating), mechanical dimensions (2.00mm height, 0.30mm thickness), and material composition (phosphor bronze contacts, LCP halogen-free housing). The primary difference is enhanced RoHS3 certification on the substitute part.

Q: What are the critical parameters that define substitution eligibility for this connector series?

A: Substitution eligibility is determined by: number of positions (28), pitch (0.5mm), mounting configuration (surface mount right angle), contact location (bottom), locking mechanism (flip lock), termination method (solder), current rating (0.5A), and operating temperature range (-40°C to 105°C). Any deviation in these parameters requires re-evaluation for compatibility.

Q: Are there packaging differences between these part numbers?

A: Both parts are supplied in Tape & Reel (TR) packaging. The FH52-28S-0.5SH(99) has higher inventory availability (2049 units) compared to FH52-28S-0.5SH (984 units), which may influence procurement decisions for high-volume applications.

Q: What compliance certifications apply to both parts?

A: Both parts meet UL94 V-0 flammability requirements, RoHS compliance standards, and MSL 1 moisture sensitivity classification. The FH52-28S-0.5SH(99) additionally carries ROHS3 certification and REACH unaffected status for enhanced regulatory documentation.

Q: Are these connectors suitable for high-temperature applications?

A: Both parts operate within the -40°C to 105°C temperature range. Applications requiring operation outside this range require alternative connector selection.
