Key Parameters

Substitute Part Grouping Explanation

Substitution of the FH19C-4S-0.5SH(89) is determined by strict alignment of the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Manufacturer: Hirose Electric Co Ltd (same manufacturer ensures design compatibility)
• Connector Category: FFC, FPC (Flat Flexible) Connectors
• Number of Positions: 4
• Pitch: 0.020" (0.50mm)
• Mounting Type: Surface Mount, Right Angle
• Connector/Contact Type: Contacts, Bottom
• Termination Method: Solder
• Voltage Rating: 50V
• Current Rating: 0.5A
• Operating Temperature Range: -55°C ~ 85°C
• Moisture Sensitivity Level: 1 (Unlimited)
• ECCN Classification: EAR99
• HTSUS Code: 8536.69.4051

The FH19C-4S-0.5SH(10) qualifies as a direct substitute based on identical alignment across all critical parameters. The primary distinction is product status: the substitute part is Active, providing superior long-term availability compared to the Obsolete main part.

Engineering Selection Recommendations

Primary Recommendation: FH19C-4S-0.5SH(10)

The FH19C-4S-0.5SH(10) is the direct equivalent for the obsolete FH19C-4S-0.5SH(89). Selection of this substitute is based on the following engineering criteria:

1. Identical Electrical Specifications: Both parts maintain 50V voltage rating, 0.5A current capacity, and -55°C ~ 85°C operating temperature range, ensuring functional equivalence in circuit applications.

2. Identical Mechanical Configuration: 4-position, 0.50mm pitch, bottom-contact, right-angle surface mount design ensures PCB layout compatibility without redesign requirements.

3. Regulatory Compliance: Both parts carry EAR99 ECCN classification and identical HTSUS coding (8536.69.4051), maintaining export and tariff compliance. The substitute achieves ROHS3 compliance, meeting current environmental standards.

4. Product Status Advantage: The substitute's Active status provides assured long-term availability and supply chain stability, eliminating obsolescence risk associated with the main part.

5. Moisture Sensitivity: Both parts maintain MSL 1 (Unlimited) rating, requiring no special handling or storage protocols.

Frequently Asked Questions (FAQ)

Q: Can FH19C-4S-0.5SH(10) be used as a direct replacement for FH19C-4S-0.5SH(89) without PCB modifications?

A: Yes. Both connectors share identical mechanical dimensions, pitch spacing (0.50mm), mounting type (surface mount, right angle), and contact configuration (4-position, bottom contacts). PCB footprints and assembly processes remain unchanged.

Q: What is the primary advantage of switching to FH19C-4S-0.5SH(10)?

A: The substitute part carries Active product status, ensuring continuous availability and supply chain reliability. The main part's Obsolete designation creates sourcing uncertainty for future production runs and field replacements.

Q: Are the electrical ratings identical between both parts?

A: Yes. Both connectors operate at 50V voltage rating with 0.5A current capacity across the -55°C ~ 85°C temperature range, maintaining electrical performance equivalence.

Q: Does packaging differ between the main part and substitute?

A: The main part packaging is unspecified in available documentation. The substitute is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly operations.

Q: Are there any compliance or certification differences?

A: Both parts maintain EAR99 ECCN classification and identical HTSUS coding. The substitute achieves ROHS3 compliance, meeting current environmental regulations. Both carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the mating cycle rating for the substitute part?

A: The FH19C-4S-0.5SH(10) is rated for 20 mating cycles, indicating durability for applications requiring connector engagement and disengagement cycles.

Q: Is the substitute part from the same manufacturer?

A: Yes. Both the main part and substitute are manufactured by Hirose Electric Co Ltd, ensuring design consistency and quality standards alignment.
