FA1-NCSP-PCB-2 Equivalent & Substitute Parts

Part Overview

The FA1-NCSP-PCB-2 is an SMB Fakra Connector Plug manufactured by Amphenol RF, designed for RF coaxial applications requiring 50 Ohm impedance. This through-hole solder-mount connector operates at frequencies up to 4 GHz and is rated for -40°C to 85°C operating temperature with 100 mating cycles. The connector features a male pin configuration with gold-plated brass contacts and PTFE dielectric material, housed in a blue signal connector body with locking ramp fastening. The part is RoHS Compliant and currently Active in product status with 1025 units in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are required but alternative form factors, frequency ratings, or mounting configurations better suit specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

The FA1-NCRP-PCB-8 is identified as a substitute for the FA1-NCSP-PCB-2 based on the following electrical and mechanical compatibility criteria:

Matching Parameters:

• Connector Style: SMB, Fakra
• Connector Type: Plug, Male Pin
• Impedance: 50 Ohms
• Contact Termination: Solder
• Shield Termination: Solder
• Mounting Type: Through Hole
• Center Contact Material: Brass
• Center Contact Plating: Gold
• Dielectric Material: Polytetrafluoroethylene (PTFE)
• Fastening Type: Locking Ramp
• Housing Color: Blue, Signal
• Number of Ports: 1

Differing Parameters:

• Mounting Configuration: FA1-NCRP-PCB-8 features right-angle orientation versus straight orientation of FA1-NCSP-PCB-2
• Frequency Rating: FA1-NCRP-PCB-8 rated to 6 GHz versus 4 GHz for FA1-NCSP-PCB-2
• Operating Temperature: FA1-NCRP-PCB-8 rated -65°C ~ 125°C versus -40°C ~ 85°C for FA1-NCSP-PCB-2
• Body Material: FA1-NCRP-PCB-8 uses Zinc Die Cast versus Brass for FA1-NCSP-PCB-2
• Body Finish: FA1-NCRP-PCB-8 has Tin finish versus Gold finish for FA1-NCSP-PCB-2
• Packaging: FA1-NCRP-PCB-8 supplied in Box versus Tray for FA1-NCSP-PCB-2
• Insertion Loss: FA1-NCRP-PCB-8 specifies 0.3dB
• RoHS Status: FA1-NCRP-PCB-8 is ROHS3 Compliant versus RoHS Compliant for FA1-NCSP-PCB-2

Substitution is applicable when PCB layout accommodates right-angle connector orientation and when extended frequency bandwidth and operating temperature range provide design margin.

Parameter Comparison

Engineering Selection Recommendations

Both FA1-NCSP-PCB-2 and FA1-NCRP-PCB-8 are Active products from Amphenol RF with full regulatory compliance. Selection between these parts is determined by PCB layout requirements and application frequency bandwidth.

FA1-NCSP-PCB-2 Selection Criteria:

• Straight through-hole connector orientation required
• Operating frequency limited to 4 GHz maximum
• Operating temperature range -40°C to 85°C sufficient
• RoHS Compliant status required
• Gold body finish preferred for corrosion resistance

FA1-NCRP-PCB-8 Selection Criteria:

• Right-angle connector orientation required for space-constrained PCB layouts
• Operating frequency up to 6 GHz required
• Extended operating temperature range -65°C to 125°C required
• ROHS3 Compliant status required
• Zinc Die Cast body with Tin finish acceptable
• Higher frequency bandwidth provides design margin for future applications

Both connectors maintain 50 Ohm impedance, identical contact materials and plating, PTFE dielectric, and equivalent mating cycle ratings. The substitute relationship is valid when PCB layout and frequency requirements align with the right-angle configuration and extended specifications of FA1-NCRP-PCB-8.

Frequently Asked Questions (FAQ)

Q: Can FA1-NCRP-PCB-8 be used as a direct replacement for FA1-NCSP-PCB-2 on existing PCBs?

A: Direct PCB replacement is not possible without layout modification. FA1-NCSP-PCB-2 is a straight through-hole connector, while FA1-NCRP-PCB-8 is right-angle. The connector orientation and mounting footprint differ, requiring PCB redesign to accommodate the right-angle configuration.

Q: Are the electrical characteristics identical between these two connectors?

A: Both connectors maintain 50 Ohm impedance, identical contact materials (brass with gold plating), and PTFE dielectric. FA1-NCRP-PCB-8 provides extended frequency bandwidth to 6 GHz compared to 4 GHz for FA1-NCSP-PCB-2. Both support equivalent mating cycles (100) and fastening methods (locking ramp).

Q: What is the difference in operating temperature ranges?

A: FA1-NCSP-PCB-2 operates from -40°C to 85°C. FA1-NCRP-PCB-8 operates from -65°C to 125°C, providing extended temperature capability for applications requiring wider thermal operating margins.

Q: How do the body materials differ and does this affect performance?

A: FA1-NCSP-PCB-2 uses brass with gold finish. FA1-NCRP-PCB-8 uses zinc die cast with tin finish. Both materials are suitable for RF coaxial connector applications. The gold finish on FA1-NCSP-PCB-2 provides enhanced corrosion resistance, while the tin finish on FA1-NCRP-PCB-8 is standard for cost-optimized applications.

Q: What is the significance of the different RoHS compliance levels?

A: FA1-NCSP-PCB-2 is RoHS Compliant (RoHS 2). FA1-NCRP-PCB-8 is ROHS3 Compliant, which represents the current regulatory standard. Both meet hazardous substance restrictions. ROHS3 compliance indicates the part meets the most recent regulatory requirements.

Q: Are these connectors supplied in different packaging formats?

A: Yes. FA1-NCSP-PCB-2 is supplied in Tray packaging. FA1-NCRP-PCB-8 is supplied in Box packaging with 2 pcs per unit (1 Connector, 1 Housing). Packaging format may affect inventory management and component handling procedures.

Q: Can these connectors be used interchangeably in RF applications up to 4 GHz?

A: Electrical interchangeability at 4 GHz is supported by both connectors' impedance and dielectric specifications. However, physical interchangeability requires matching PCB layout to the connector orientation (straight versus right-angle). Substitution is valid only when PCB design accommodates the right-angle mounting of FA1-NCRP-PCB-8.

Q: What does the "Code C" feature designation indicate?

A: Both connectors include Code C feature designation, indicating they conform to the same Fakra connector code specification for this connector family.
