Key Parameters

Substitute Part Grouping Explanation

Substitution of HRM-508S(40) is based on the following critical parameters derived from the product category and electrical specifications:

• Base product number alignment (HRM-508 series)
• Manufacturer consistency (Hirose Electric Co Ltd)
• Impedance specification (50 Ohms)
• Coaxial connector category classification
• Regulatory compliance (ECCN: EAR99, HTSUS: 8536.69.4010)
• Product status transition from obsolete to active alternatives

The substitute part HRM-508S(31) maintains identical base product lineage, manufacturer origin, impedance rating, and regulatory classification while offering active product status and current inventory availability.
