Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PA9751 are identified based on functional and mechanical equivalence within the coaxial connector adapter category. The following parameters establish substitution eligibility:

Critical Matching Parameters:

• Adapter Type: Plug to Jack
• Adapter Series: BNC to F
• Center Gender: Female to Male
• Convert From: BNC Plug, Male Pin
• Convert To: F Jack, Female Socket
• Style: Straight
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Bayonet Lock, Threaded

The substitute part 242154 (Amphenol RF) satisfies all critical matching parameters and provides additional technical specifications including impedance rating, operating temperature range, and material composition that were not specified for the PA9751.

Parameter Comparison

Engineering Selection Recommendations

The PA9751 is obsolete and no longer in active production. The 242154 (Amphenol RF) is the identified equivalent substitute, classified as active product status with current manufacturing support.

Selection Basis:

The 242154 maintains functional and mechanical equivalence to the PA9751 across all critical adapter parameters: BNC to F conversion, plug-to-jack configuration, straight in-line mounting, and bayonet lock fastening.

The 242154 provides additional compliance certifications including ROHS3 compliance and REACH affected status, supporting modern regulatory requirements. The part is specified with 75 Ohms impedance and operates across -65°C to 165°C, establishing defined performance boundaries for RF applications.

Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications, confirming trade and export equivalence.

Frequently Asked Questions (FAQ)

Q: Can the 242154 directly replace the PA9751 in existing designs?
