Engineering Selection Recommendations

FH52-50S-0.5SH(99) is a parametric equivalent manufactured by Hirose Electric Co Ltd. This part maintains identical electrical and mechanical specifications to the primary part number, with ROHS3 compliance certification. Selection of this variant is appropriate when ROHS3 compliance is a design requirement. Both parts are active in production with substantial inventory availability.

10085901-50115ELF manufactured by Amphenol ICC (FCI) is a functional substitute with the following considerations: The part is currently obsolete and inventory is limited to 946 units. Operating temperature range is reduced to -55°C to 85°C, which may not satisfy applications requiring the full -40°C to 105°C range of the primary part. The locking mechanism differs (Slide Lock vs. Flip Lock), and cable end type is tapered rather than tabbed. Contact material is copper alloy instead of phosphor bronze. This part includes Zero Insertion Force (ZIF) functionality and 50V voltage rating. Selection of this substitute is limited to applications where the reduced operating temperature range and mechanical differences are acceptable, and only when inventory constraints on the primary part necessitate substitution.

Frequently Asked Questions (FAQ)

Q: Can FH52-50S-0.5SH(99) be used as a direct replacement for FH52-50S-0.5SH?

A: Yes. FH52-50S-0.5SH(99) is a parametric equivalent with identical electrical and mechanical specifications. The primary difference is ROHS3 compliance certification versus RoHS compliance. Both parts are manufactured by Hirose Electric Co Ltd and are active in production.

Q: What are the key differences between FH52-50S-0.5SH and 10085901-50115ELF?

A: Both connectors share the same 50-position, 0.5mm pitch, surface mount right-angle configuration. However, 10085901-50115ELF has a reduced operating temperature range (-55°C to 85°C versus -40°C to 105°C), uses a slide lock mechanism instead of flip lock, features tapered cable ends instead of tabbed, and employs copper alloy contacts instead of phosphor bronze. The Amphenol part is currently obsolete.

Q: Is the 10085901-50115ELF suitable for high-temperature applications?

A: No. The maximum operating temperature of 10085901-50115ELF is 85°C, which is below the 105°C maximum of the FH52-50S-0.5SH. Applications requiring operation above 85°C must use the primary part or its parametric equivalent.

Q: What is the significance of the locking mechanism difference?

A: The FH52-50S-0.5SH uses a flip lock mechanism, while 10085901-50115ELF uses a slide lock mechanism. These are different mechanical actuation methods for securing the FFC/FPC cable. Compatibility depends on the cable connector design and PCB layout. Mechanical verification is required before substitution.

Q: Are all three parts RoHS compliant?

A: FH52-50S-0.5SH and 10085901-50115ELF are RoHS Compliant. FH52-50S-0.5SH(99) is ROHS3 Compliant, which represents a more recent certification standard. All three parts meet halogen-free requirements and UL94 V-0 flammability ratings.

Q: What inventory considerations should guide part selection?

A: FH52-50S-0.5SH has 4312 units in stock, FH52-50S-0.5SH(99) has 3634 units, and 10085901-50115ELF has 946 units. The primary part and its parametric equivalent offer substantially higher availability. The Amphenol part, being obsolete, should be considered only when primary options are exhausted and application parameters permit the noted variations.
