Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for FFC/FPC connectors in the FH28 series is determined by strict equivalence across the following critical parameters:

• Number of Positions: 55
• Pitch: 0.020" (0.50mm)
• Mounting Type: Surface Mount, Right Angle
• Connector/Contact Type: Contacts, Bottom
• Voltage Rating: 50V
• Current Rating: 0.5A
• Operating Temperature Range: -40°C ~ 105°C
• Locking Feature: Rotary Lock
• Features: Solder Retention, Zero Insertion Force (ZIF)
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)

All three substitute parts—FH28-55S-0.5SH(05), FH28-55S-0.5SH(10), and FH28D-55S-0.5SH(05)—maintain identical electrical and mechanical specifications across these parameters. The differences in part number suffixes reflect manufacturing date codes or packaging variants that do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The FH28-55S-0.5SH(98) is designated Last Time Buy status. For new designs or ongoing production requiring this connector specification, FH28-55S-0.5SH(05), FH28-55S-0.5SH(10), and FH28D-55S-0.5SH(05) are functionally equivalent alternatives with Active product status.

FH28-55S-0.5SH(05) carries ROHS3 Compliant certification, providing enhanced regulatory alignment for applications subject to updated RoHS directives. FH28-55S-0.5SH(10) and FH28D-55S-0.5SH(05) maintain standard RoHS Compliant status. All three substitutes are manufactured by Hirose Electric Co Ltd and maintain identical electrical, mechanical, and environmental specifications as the main part.

Inventory availability is highest for FH28-55S-0.5SH(05) at 2020 units, followed by FH28D-55S-0.5SH(05) at 1641 units and FH28-55S-0.5SH(10) at 942 units, providing supply chain flexibility for production planning.

Frequently Asked Questions (FAQ)

Q: Can FH28-55S-0.5SH(05), FH28-55S-0.5SH(10), and FH28D-55S-0.5SH(05) be used interchangeably with FH28-55S-0.5SH(98)?

A: Yes. All three substitute parts maintain identical electrical specifications (50V voltage rating, 0.5A current rating), mechanical configuration (55 positions, 0.5mm pitch, surface mount right-angle), operating temperature range (-40°C ~ 105°C), and functional features (rotary lock, ZIF operation, solder retention). The part number suffixes reflect manufacturing date codes or packaging variants that do not affect functional compatibility.

Q: What is the difference between the three substitute parts?

A: The primary differences are product status and regulatory compliance. FH28-55S-0.5SH(05) is ROHS3 Compliant, while FH28-55S-0.5SH(10) and FH28D-55S-0.5SH(05) are RoHS Compliant. All three are Active products with sufficient inventory. The "D" designation in FH28D-55S-0.5SH(05) indicates a variant within the FH28 series but does not affect electrical or mechanical compatibility.

Q: Why is the main part FH28-55S-0.5SH(98) in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer is discontinuing this specific date code or variant. Equivalent substitutes with Active status are available to ensure design continuity and supply chain stability.

Q: Are there any compliance or certification differences between the main part and substitutes?

A: All parts are UL94 V-0 rated and MSL 1 (Unlimited). FH28-55S-0.5SH(05) carries ROHS3 Compliant certification, providing alignment with updated regulatory requirements. FH28-55S-0.5SH(10) and FH28D-55S-0.5SH(05) maintain standard RoHS Compliant status. Selection should be based on specific regulatory requirements for the application.

Q: Can I mix different substitute parts in the same production run?

A: Yes. All three substitutes are functionally equivalent and maintain identical electrical and mechanical specifications. However, for consistency in manufacturing records and traceability, it is standard practice to use a single part number per production batch.
