Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Amphenol RF 901-9888 are classified into two categories based on parametric alignment:

Parametric Equivalent: Part 132147-48 (Amphenol RF) maintains identical electrical and mechanical specifications across all critical parameters: SMA connector style, receptacle female socket configuration, 50 Ohm impedance, solder termination for both contact and shield, panel mount with flange, threaded fastening, 12.4 GHz maximum frequency, beryllium copper center contact, PTFE dielectric, 500 mating cycles, and -65°C to 165°C operating temperature. This part qualifies as a direct parametric equivalent with full interchangeability.

Similar Manufacturer Parts: Parts HRM(V)-301S and HRM(V)-306S (Hirose Electric Co Ltd) share the core SMA connector architecture, receptacle female socket type, 50 Ohm impedance, solder termination, panel mount configuration with flange, threaded fastening, beryllium copper center contact, and PTFE dielectric. However, these parts exhibit differences in maximum frequency (18 GHz versus 12.4 GHz), operating temperature range (-55°C to 85°C versus -65°C to 165°C), body material (stainless steel versus brass), and housing color (silver versus gold). The HRM(V)-306S carries Obsolete product status, whereas HRM(V)-301S remains Active.

Substitution logic is based strictly on matching: connector style, connector type, impedance rating, termination methods, mounting configuration, fastening mechanism, center contact material, and dielectric material. Frequency capability, temperature range, and product status are documented for engineering selection context.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute - 132147-48 (Amphenol RF): This part is the recommended parametric equivalent for direct replacement of the 901-9888. All electrical and mechanical parameters align identically, including impedance, frequency rating, operating temperature range, and termination specifications. Both parts carry Active product status and ROHS3 compliance. Inventory availability is higher at 2200 pieces. This substitution requires no design modification and maintains full functional equivalence.

Alternative Substitutes - HRM(V)-301S (Hirose Electric Co Ltd): This part provides functional compatibility within applications operating below 12.4 GHz and within the -55°C to 85°C temperature window. The HRM(V)-301S maintains Active product status and ROHS3 compliance. The extended frequency capability (18 GHz) and identical core parameters (SMA style, 50 Ohm impedance, solder termination, PTFE dielectric, beryllium copper contact) support substitution in designs not requiring the full -65°C to 165°C temperature range of the original part. Inventory is available at 1923 pieces.

Not Recommended - HRM(V)-306S (Hirose Electric Co Ltd): This part carries Obsolete product status and should not be selected for new designs or long-term production applications. Although parametric compatibility exists with the HRM(V)-301S, the obsolete classification indicates discontinued manufacturing and limited future availability.

Selection should prioritize Active status parts (901-9888, 132147-48, HRM(V)-301S) and verify application temperature and frequency requirements against the documented operating ranges.

Frequently Asked Questions (FAQ)

Q: Can 132147-48 replace 901-9888 without any design changes?

A: Yes. The 132147-48 is a parametric equivalent with identical specifications across all critical parameters: SMA connector style, receptacle female socket configuration, 50 Ohm impedance, solder termination, panel mount with flange, threaded fastening, 12.4 GHz maximum frequency, beryllium copper center contact, PTFE dielectric, 500 mating cycles, and -65°C to 165°C operating temperature. Direct substitution is supported without circuit or layout modification.

Q: What are the key differences between the Amphenol RF and Hirose parts?

A: The Amphenol RF parts (901-9888 and 132147-48) use brass body material with gold finish, while Hirose parts (HRM(V)-301S and HRM(V)-306S) use stainless steel body. Amphenol RF parts operate across -65°C to 165°C, whereas Hirose parts are rated -55°C to 85°C. Hirose parts support higher maximum frequency (18 GHz versus 12.4 GHz). All parts share identical impedance (50 Ohms), connector style (SMA), termination method (solder), and dielectric material (PTFE).

Q: Can HRM(V)-301S be used in applications requiring -65°C operation?

A: No. The HRM(V)-301S operating temperature range is -55°C to 85°C. Applications requiring operation at -65°C must use 901-9888 or 132147-48, both rated to -65°C minimum. Temperature specification mismatch can result in connector performance degradation or failure.

Q: Why is HRM(V)-306S listed if it is obsolete?

A: The HRM(V)-306S is documented for reference purposes only, as it appears in the substitute list for the main part. Obsolete status indicates discontinued manufacturing. New designs and production applications should not select this part. Active alternatives (901-9888, 132147-48, HRM(V)-301S) are available with confirmed ongoing supply.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed parts carry RoHS compliance: 901-9888 and 132147-48 are ROHS3 Compliant, while HRM(V)-301S is ROHS3 Compliant and HRM(V)-306S is RoHS Compliant. All parts meet environmental regulatory requirements for lead-free and restricted substance standards.

Q: What is the significance of the MSL rating?

A: All parts carry MSL (Moisture Sensitivity Level) rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors do not require special moisture control during storage, handling, or assembly, simplifying supply chain and manufacturing logistics.

Q: Can frequency differences affect substitution decisions?

A: Frequency differences should be evaluated against application requirements. The 901-9888 and 132147-48 are rated to 12.4 GHz maximum. The Hirose parts (HRM(V)-301S and HRM(V)-306S) support 18 GHz. If the application operates below 12.4 GHz, all parts are suitable. If operation above 12.4 GHz is required, only Hirose parts qualify. Conversely, if the application requires the full -65°C to 165°C temperature range, only Amphenol RF parts are suitable.
