• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Threaded
• Center Contact Material: Beryllium Copper
• Body Material: Stainless Steel
• Dielectric Material: Polytetrafluoroethylene (PTFE)
• Mating Cycles: 500

Allowable Variation Parameters:

• Frequency - Max: Substitute must support the application frequency requirement; higher frequency ratings are acceptable
• Operating Temperature Range: Substitute must encompass or exceed the operating range of the original part
• Cable Group: Substitutes may support different cable groups (RG-402 or RG-405) depending on application requirements
• Product Status: Active status substitutes are preferred for obsolete parts
• RoHS/Compliance Status: Substitutes must maintain or exceed compliance certifications

The substitute parts listed below satisfy these criteria and provide direct functional equivalence for the 1050762-1 in SMA coaxial connector applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: Amphenol RF 901-9808-2

The 901-9808-2 is the direct functional equivalent for the 1050762-1. Both connectors support RG-402 (.141" semi-rigid) cable, maintain identical mechanical and electrical specifications for the core connector interface, and are rated for 500 mating cycles. The 901-9808-2 is currently in active production status with ROHS3 compliance and REACH affected status, ensuring long-term supply chain availability. The operating temperature range of -65°C to 165°C exceeds the original part specification, providing enhanced thermal margin. The maximum frequency rating of 18 GHz is lower than the original 26.5 GHz specification; this substitution is appropriate for applications operating below 18 GHz.

Secondary Substitutes: Amphenol RF 901-9201-1ASF and 901-9201-2ASF

Both 901-9201 series connectors provide functional equivalence with active product status and ROHS3 compliance. The 901-9201-1ASF maintains RG-402 cable compatibility identical to the original part. The 901-9201-2ASF supports RG-405 (.085", .086" semi-rigid) cable and includes weatherproof ingress protection, suitable for applications requiring different cable geometries or environmental protection. Both variants operate at -65°C to 165°C and are rated for 18 GHz maximum frequency.

Compliance Considerations

All substitute parts maintain or exceed the RoHS compliance status of the original 1050762-1. The Amphenol RF substitutes carry ROHS3 certification and REACH affected status, meeting current regulatory requirements for electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can the 901-9808-2 directly replace the 1050762-1 in existing designs?

A: The 901-9808-2 provides direct mechanical and electrical compatibility for applications operating at frequencies up to 18 GHz. Both connectors use identical SMA plug configuration, 50 Ohm impedance, solder termination, and RG-402 cable compatibility. The primary design consideration is the frequency rating: if your application operates below 18 GHz, the 901-9808-2 is a direct substitute. If your application requires operation above 18 GHz, the frequency limitation of the substitute must be evaluated against your specific performance requirements.

Q: What is the difference between the 901-9201-1ASF and 901-9201-2ASF?

A: The 901-9201-1ASF is configured for RG-402 (.141" semi-rigid) cable, matching the original 1050762-1 cable specification. The 901-9201-2ASF is configured for RG-405 (.085", .086" semi-rigid) cable and includes weatherproof ingress protection. Select the 901-9201-1ASF for direct cable compatibility or the 901-9201-2ASF if your application uses smaller diameter semi-rigid cable or requires environmental sealing.

Q: Are there frequency limitations when substituting the 1050762-1?

A: The original 1050762-1 is rated to 26.5 GHz. All listed substitute parts (901-9808-2, 901-9201-1ASF, 901-9201-2ASF) are rated to 18 GHz maximum frequency. Substitution is appropriate for applications operating at or below 18 GHz. Applications requiring operation above 18 GHz cannot use these substitutes without performance degradation.

Q: Do the substitute parts meet current RoHS requirements?

A: Yes. All substitute parts carry ROHS3 certification, which exceeds the RoHS compliance status of the original 1050762-1. The Amphenol RF substitutes also carry REACH affected status, meeting current European regulatory requirements.

Q: What is the operating temperature range difference between the original and substitute parts?

A: The 1050762-1 operates from -65°C to 105°C. All substitute parts operate from -65°C to 165°C. The substitutes provide a 60°C higher upper temperature limit, offering enhanced thermal margin for applications in elevated temperature environments.

Q: Can I use the 901-9201-2ASF with RG-402 cable?

A: No. The 901-9201-2ASF is configured for RG-405 (.085", .086" semi-rigid) cable. For RG-402 cable compatibility, use the 901-9808-2 or 901-9201-1ASF.

Q: What is the inventory status of these substitute parts?

A: The 901-9808-2 has 687 pieces in stock, the 901-9201-1ASF has 866 pieces in stock, and the 901-9201-2ASF has 1004 pieces in stock. All substitutes are currently available in active production.
