Substitute Part Grouping Explanation

Substitution eligibility for the FH41-30S-0.5SH(99) is determined by strict equivalence across the following critical parameters:

• Connector Series & Base Product: Must be FH41 series from Hirose Electric Co Ltd
• Position Count: Exactly 30 positions
• Pitch Specification: 0.020" (0.50mm) contact spacing
• Mounting Configuration: Surface mount, right-angle orientation
• Contact Arrangement: Bottom-contact configuration
• Termination Method: Solder termination
• Electrical Ratings: 50V voltage rating and 0.5A current rating per contact
• Operating Temperature: -40°C to 105°C range
• Material Compliance: Halogen-free housing and actuator materials with UL94 V-0 flammability rating

The substitute part FH41-30S-0.5SH(05) meets all these criteria and is therefore a direct parametric equivalent. Differences in packaging designation (99 vs. 05) and inventory levels do not affect functional or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the FH41-30S-0.5SH(99) and FH41-30S-0.5SH(05) are active production parts from Hirose Electric Co Ltd and are fully interchangeable for all design and manufacturing applications. The FH41-30S-0.5SH(05) variant offers higher inventory availability (5841 pieces versus 853 pieces), making it the preferred selection for procurement when supply chain continuity is a consideration. Both parts maintain identical compliance certifications including RoHS compliance, UL94 V-0 flammability rating, and EAR99 export classification. The ROHS3 designation for the FH41-30S-0.5SH(05) represents an updated compliance documentation standard and does not indicate functional or material differences. Selection between these parts should be based on inventory availability, lead time requirements, and supplier preference, as all electrical, mechanical, and environmental specifications are equivalent.

Frequently Asked Questions (FAQ)

Q: Are FH41-30S-0.5SH(99) and FH41-30S-0.5SH(05) mechanically interchangeable?

A: Yes. Both parts are identical in all mechanical dimensions, including pitch (0.50mm), position count (30), height above board (2.50mm), and mounting configuration (surface mount, right angle). They use the same housing and actuator materials and feature identical locking mechanisms.

Q: Can I substitute FH41-30S-0.5SH(05) for FH41-30S-0.5SH(99) in existing PCB designs?

A: Yes. The parts are direct parametric equivalents with no design modifications required. PCB footprints, assembly procedures, and electrical connections remain unchanged.

Q: What do the designations (99) and (05) represent?

A: These designations indicate different packaging or sourcing batches from Hirose Electric Co Ltd. They do not reflect functional, electrical, or mechanical differences between the parts.

Q: Are both parts RoHS compliant?

A: Yes. FH41-30S-0.5SH(99) is RoHS Compliant, and FH41-30S-0.5SH(05) is ROHS3 Compliant. Both meet RoHS requirements. ROHS3 represents an updated compliance documentation standard.

Q: What is the maximum current and voltage rating for these connectors?

A: Both parts are rated for 50V maximum voltage and 0.5A maximum current per contact. Operating temperature range is -40°C to 105°C.

Q: Are there any differences in contact finish or material composition?

A: No. Both parts feature phosphor bronze contacts with gold finish, halogen-free LCP housing and actuator materials, and identical solder retention features.

Q: Which part should I select for new designs?

A: Either part is suitable for new designs. Selection should be based on current inventory availability and supplier lead times, as both are active production parts with identical specifications.
