Substitute Part Grouping Explanation

Substitution eligibility for the N.FL-R-SMT-1(10) is determined by the following critical parameters:

Connector Style: U.FL (UMCC)
Connector Type: Receptacle, Male Pin
Impedance: 50 Ohms
Mounting Type: Surface Mount
Contact Termination: Solder
Shield Termination: Solder
Frequency - Max: 6 GHz

Engineering Selection Recommendations

All three substitute parts are functionally equivalent to the N.FL-R-SMT-1(10) based on the critical electrical and mechanical parameters. The primary distinction is product status: the N.FL-R-SMT-1(10) is in Last Time Buy status, while X.FL-R-SMT-1(02), X.FL-R-SMT-1(80), and X.FL-R-SMT-1(90) are all Active products.

For new designs or long-term production requirements, selection from the active substitute parts is appropriate. X.FL-R-SMT-1(02) offers the highest inventory availability (14,332 pcs), followed by X.FL-R-SMT-1(80) (9,448 pcs) and X.FL-R-SMT-1(90) (667 pcs). All substitute parts maintain ROHS compliance and EAR99 export classification consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Are the X.FL-R-SMT-1 series parts electrically compatible with the N.FL-R-SMT-1(10)?

A: Yes. All substitute parts maintain identical impedance (50 Ohms), frequency rating (6 GHz), connector style (U.FL/UMCC), and termination specifications (Solder). Electrical performance is equivalent within the specified operating parameters.

Q: What is the difference between the N.FL and X.FL series designations?

A: The series designation reflects the base product line. Both N.FL and X.FL series connectors in this comparison share identical electrical and mechanical specifications for the receptacle, male pin configuration. The series letter does not indicate functional differences for this connector type.

Q: Does the body finish variation (Silver vs. Gold) affect compatibility?

A: No. Body finish is a cosmetic and corrosion-resistance characteristic that does not affect electrical performance or mechanical mating. Both Silver (N.FL-R-SMT-1(10)) and Gold finishes (X.FL variants) are suitable for the same applications.

Q: Why is the N.FL-R-SMT-1(10) in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer is discontinuing this specific part number. Active equivalent alternatives are available to support ongoing production and design requirements.

Q: Can I use these connectors interchangeably on the same PCB assembly?

A: Yes. All parts share identical footprints, solder pad configurations, and mechanical mounting requirements for surface mount assembly. No PCB redesign is required for substitution.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All parts in this comparison carry this rating, eliminating moisture sensitivity as a selection factor.
