Key Parameters

Substitute Part Grouping Explanation

Substitution of the 221540-1 is determined by strict alignment of electrical and mechanical parameters. The primary substitution criteria include:

Critical Parameters for Substitution:

• Connector Style: F Type
• Connector Type: Plug, Male Pin
• Impedance: 75 Ohms
• Mounting Type: Free Hanging (In-Line)
• Cable Group: RG-59
• Number of Ports: 1
• Voltage Rating: 500 V
• Operating Temperature Range: -65°C ~ 85°C

Secondary Parameters Affecting Compatibility:

• Shield Termination Method (Twist On vs. Crimp)
• Fastening Type (Threaded vs. Push-Twist)
• Frequency Maximum Rating
• Product Status (Active vs. Obsolete)
• RoHS Compliance Status

The TE Connectivity AMP Connectors 414766-8 maintains full electrical and mechanical compatibility with the 221540-1, with the primary difference being shield termination method (Crimp vs. Twist On) and active product status. The Winchester Interconnect 810A409G presents a partial substitute with non-constant impedance and reduced frequency rating, requiring engineering evaluation for specific applications.

Engineering Selection Recommendations

TE Connectivity AMP Connectors 414766-8

The 414766-8 is the primary equivalent substitute for the obsolete 221540-1. Both components maintain identical electrical specifications including 75 Ohm impedance, 1 GHz frequency rating, 500 V voltage rating, and -65°C to 85°C operating temperature range. The 414766-8 carries Active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The primary operational difference is the shield termination method (Crimp vs. Twist On), which does not affect electrical performance but requires appropriate termination tooling. The 414766-8 is available in Bulk packaging with 1065 pieces in stock.

Winchester Interconnect 810A409G

The 810A409G presents a secondary substitute option with significant parameter deviations. This connector features non-constant impedance, reduced maximum frequency rating (500 MHz vs. 1 GHz), narrower operating temperature range (-40°C to 65°C vs. -65°C to 85°C), and push-twist fastening instead of threaded fastening. The 810A409G is suitable only for applications where the reduced frequency and temperature specifications are acceptable. RoHS compliance is confirmed. This component is available with 807 pieces in stock.

Frequently Asked Questions (FAQ)

Q: Can the 414766-8 directly replace the 221540-1 in all applications?

A: The 414766-8 maintains full electrical and mechanical compatibility with the 221540-1 for standard F Type coaxial connector applications. The primary difference is shield termination method. The 221540-1 uses twist-on termination while the 414766-8 uses crimp termination. Both methods achieve equivalent electrical performance when properly executed. Termination tooling requirements differ between the two methods.

Q: What are the impedance implications of using the 810A409G?

A: The 810A409G features non-constant impedance, whereas the 221540-1 and 414766-8 both maintain constant 75 Ohm impedance. Non-constant impedance introduces impedance discontinuities that may affect signal integrity in high-frequency applications. The 810A409G is limited to 500 MHz maximum frequency compared to 1 GHz for the primary part. Applications requiring constant impedance characteristics should use the 414766-8.

Q: Are there packaging differences between the substitute parts?

A: The 221540-1 packaging specification is not provided in the technical data. The 414766-8 is supplied in Bulk packaging. The 810A409G packaging specification is not provided. Packaging differences do not affect connector performance but may impact procurement and inventory management processes.

Q: What is the significance of the operating temperature range difference in the 810A409G?

A: The 810A409G operates within -40°C to 65°C, which is narrower than the 221540-1 and 414766-8 range of -65°C to 85°C. Applications requiring operation at temperatures below -40°C or above 65°C must use the 414766-8 or 221540-1. The 810A409G is unsuitable for extreme temperature environments.

Q: How does the fastening type difference affect installation?

A: The 221540-1 uses threaded fastening while the 810A409G uses push-twist fastening. The 414766-8 maintains threaded fastening identical to the main part. Fastening type affects mating procedure and mechanical retention characteristics. Threaded fastening provides consistent torque-based connection, while push-twist fastening relies on rotational engagement. The 414766-8 requires no installation procedure changes from the 221540-1.

Q: What is the RoHS compliance status for each part?

A: The 221540-1 carries "Not applicable" RoHS status. The 414766-8 is ROHS3 Compliant. The 810A409G is RoHS Compliant. For applications requiring RoHS compliance, both the 414766-8 and 810A409G are acceptable. The 414766-8 provides the most current compliance standard (ROHS3).

Q: Are there frequency limitations when substituting with the 810A409G?

A: The 810A409G maximum frequency rating is 500 MHz compared to 1 GHz for the 221540-1 and 414766-8. Applications operating above 500 MHz must use the 414766-8. The 810A409G is suitable only for applications operating at or below 500 MHz.
