Equivalent & Substitute Parts: 8313505

Part Overview

The 8313505 is an F Plug to BNC Jack coaxial adapter manufactured by Winchester Interconnect. This adapter serves as an in-line connector for RF applications requiring conversion between F-series and BNC-series coaxial connectors. The part is currently active in production with 1097 units in stock. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when specific application requirements necessitate alternative specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for coaxial adapters is determined by the following critical parameters:

Mandatory Matching Parameters:

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

Allowable Variation Parameters:

• Impedance: 50 Ohms (main part) vs. 75 Ohms (substitute) — impedance differences are application-dependent and must be evaluated by the end user
• Frequency - Max: 1 GHz (main part) vs. 4 GHz (substitute) — higher frequency capability in substitute provides extended operational range
• Body Material: Brass (main part) vs. unspecified (substitute) — material differences do not affect electrical performance when body finish is equivalent
• Center Contact Material: Brass (main part) vs. Phosphor Bronze (substitute) — both materials support gold plating and maintain electrical integrity
• RoHS Status: RoHS Compliant (main part) vs. ROHS3 Compliant (substitute) — both meet regulatory requirements; ROHS3 represents updated compliance standard

The substitute part AD1300 maintains functional equivalence in connector geometry, mating interface, and mechanical fastening while offering enhanced frequency performance.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (8313505): Select the 8313505 when the application operates at frequencies up to 1 GHz and requires 50-ohm impedance matching. This part is RoHS Compliant and maintains active production status with established inventory availability.

Substitute Part Selection (AD1300): The AD1300 is suitable as a substitute when higher frequency performance (up to 4 GHz) is required or when 75-ohm impedance is acceptable for the application. The AD1300 meets ROHS3 compliance, representing current regulatory standards. Note that the AD1300 connector orientation is reversed (BNC Jack to F Plug) compared to the main part (F Plug to BNC Jack); this reversal does not affect functional equivalence in adapter applications but must be verified against specific cable assembly requirements.

Both parts share identical mechanical fastening (Bayonet Lock, Threaded), mounting configuration (Free Hanging In-Line), and contact plating (Gold), ensuring physical and electrical compatibility within their respective impedance and frequency specifications.

Frequently Asked Questions (FAQ)

Q: Can AD1300 be used as a direct replacement for 8313505?

A: The AD1300 provides functional equivalence for BNC-to-F conversion with identical mechanical interfaces and fastening methods. However, two differences require evaluation: (1) impedance differs (75 Ohms vs. 50 Ohms), and (2) connector orientation is reversed. Substitution is valid only if the application tolerates 75-ohm impedance and the reversed connector orientation aligns with cable assembly requirements.

Q: What is the significance of the impedance difference between 50 Ohms and 75 Ohms?

A: Impedance matching is application-dependent. 50-ohm systems are standard in RF and microwave applications, while 75-ohm systems are common in video and broadband applications. Impedance mismatch introduces signal reflections and insertion loss. Substitution across impedance classes requires confirmation that the end application can accommodate the impedance difference.

Q: Does the higher frequency rating of AD1300 (4 GHz vs. 1 GHz) affect compatibility?

A: Higher frequency capability does not create incompatibility. The AD1300 operates across a broader frequency range and is suitable for applications up to 4 GHz. For applications operating below 1 GHz, both parts perform equivalently within their respective impedance specifications.

Q: Are there packaging differences between these parts?

A: The 8313505 is supplied in unspecified packaging, while AD1300 is supplied in Bulk packaging. Packaging differences do not affect component performance but may influence procurement quantities and handling procedures.

Q: What compliance standards apply to each part?

A: The 8313505 is RoHS Compliant. The AD1300 is ROHS3 Compliant and REACH Affected. Both meet current environmental and regulatory requirements. ROHS3 represents the updated RoHS directive standard. Both parts carry MSL Rating 1 (Unlimited moisture sensitivity).

Q: Can these adapters be used interchangeably in existing assemblies?

A: Interchangeability depends on the specific assembly design. The reversed connector orientation (F Plug to BNC Jack vs. BNC Jack to F Plug) must be verified against the cable assembly configuration. Impedance compatibility with the system must also be confirmed before substitution.
