FH21-8S-1DS Equivalent & Substitute Parts

Part Overview

The FH21-8S-1DS is an 8-position FFC/FPC connector manufactured by Hirose Electric Co Ltd, designed for flat flexible cable applications with 1.00mm pitch and right-angle through-hole mounting. This connector features top and bottom contacts with kinked pin termination and low insertion force operation. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FH21-8S-1DS is determined by the following critical parameters:

• Connector Position Count: Must be 8 positions
• Pitch Specification: Must be 0.039" (1.00mm)
• Mounting Configuration: Must be through-hole, right-angle orientation
• Electrical Ratings: Voltage rating of 50V and current rating of 0.5A minimum
• FFC/FPC Compatibility: Must support flat flexible cable applications
• Cable Thickness: FFC/FCB thickness of 0.30mm

The substitute part 006232008104800+ from KYOCERA AVX meets these core substitution criteria. However, the contact configuration differs: the FH21-8S-1DS provides top and bottom contacts, while the substitute provides bottom contacts only. This represents a functional difference that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The 006232008104800+ from KYOCERA AVX is an active product with current manufacturing support, addressing the obsolescence status of the FH21-8S-1DS. The substitute maintains electrical compatibility with identical voltage and current ratings, and shares the same pitch and position count specifications.

Key considerations for selection:

• Product Status: The substitute is active and in production, ensuring long-term availability compared to the obsolete main part.
• RoHS Compliance: The substitute meets ROHS3 compliance requirements, whereas the main part is non-compliant. This may be mandatory depending on application and regulatory jurisdiction.
• Contact Configuration: The substitute provides bottom contacts only, whereas the main part provides top and bottom contacts. This difference requires evaluation against specific PCB layout and signal routing requirements.
• Height Variation: The substitute has a 0.012" (0.30mm) greater height above board, which may impact clearance in space-constrained applications.
• Operating Temperature Range: The substitute supports an extended upper temperature limit of 85°C compared to 70°C for the main part.

Frequently Asked Questions (FAQ)

Q: Can the 006232008104800+ directly replace the FH21-8S-1DS in all applications?

A: Direct replacement depends on contact configuration requirements. The main part provides top and bottom contacts, while the substitute provides bottom contacts only. If your application requires top contact access, the substitute may not be suitable without PCB redesign.

Q: What is the significance of the contact configuration difference?

A: Contact configuration determines which side of the PCB the connector interfaces with. Top and bottom contacts allow dual-sided connectivity, while bottom-only contacts restrict connectivity to the bottom side. This affects signal routing and PCB layout.

Q: Does the height difference affect compatibility?

A: The substitute is 0.30mm taller above the board. This may impact clearance in applications with height constraints or adjacent components. Verify clearance in your specific mechanical design.

Q: Is RoHS compliance mandatory for substitution?

A: RoHS compliance requirements depend on your application's regulatory jurisdiction and customer specifications. If ROHS3 compliance is required, the substitute meets this requirement while the main part does not.

Q: Are the electrical ratings identical?

A: Yes. Both parts maintain 50V voltage rating and 0.5A current rating, ensuring electrical compatibility for signal integrity and power delivery specifications.

Q: What is the pitch specification and why does it matter?

A: Pitch is 0.039" (1.00mm) for both parts. Pitch determines the spacing between connector positions and must match the flat flexible cable design. Mismatched pitch prevents proper mating.
