RFSMAA4PAAC SMA Coaxial Connector Equivalent & Substitute Parts

Part Overview

The RFSMAA4PAAC is an SMA connector plug manufactured by Bulgin, designed for 50 Ohm RF applications requiring panel mount installation with four-hole flange mounting. This male pin connector operates across frequencies up to 26.5 GHz and utilizes compression contact termination with screw shield termination. The part is Active in product status with 897 units currently in stock. Substitute parts are identified when mechanical mounting configurations differ while maintaining identical electrical performance and environmental specifications, enabling design flexibility and supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RFSMAA4PAAC are identified based on electrical and environmental parameter equivalence. The primary substitution criterion is the maintenance of identical electrical specifications: SMA connector style, male pin configuration, 50 Ohm impedance, 26.5 GHz maximum frequency, compression contact termination, and screw shield termination. All substitute parts operate within the same temperature range (-65°C ~ 165°C), voltage rating (335 V), and mating cycle specification (500 cycles).

The key differentiating parameter among substitute parts is the mounting feature configuration. The RFSMAA4PAAC features a four-hole flange mount, while the RFSMAA2PEGA features a two-hole flange mount. Both configurations provide panel mount installation with flange-based fastening using threaded fasteners. This mechanical variation does not affect electrical performance or RF characteristics, allowing substitution based on specific panel layout requirements.

All substitute parts share identical material specifications: beryllium copper center contact, stainless steel body, and polyetherimide (PEI) dielectric material. Compliance certifications remain consistent across all parts: ROHS3 Compliant, MSL Level 1, ECCN EAR99, and HTSUS 8536.69.4010.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RFSMAA4PAAC, RFSMAA2PEGA, and RFSMAA4PCCA—are Active products manufactured by Bulgin with identical electrical and environmental specifications. Selection between these parts is determined solely by panel mounting hole configuration requirements.

RFSMAA4PAAC and RFSMAA4PCCA are electrically and mechanically equivalent, both featuring four-hole flange mounting. These parts are interchangeable for applications requiring four-hole panel mount installation. RFSMAA4PCCA currently has the highest inventory availability at 1057 units.

RFSMAA2PEGA provides an alternative for applications where two-hole flange mounting is specified. This part maintains all electrical performance characteristics and environmental ratings while accommodating different panel layout geometries.

All parts maintain ROHS3 compliance and MSL Level 1 rating, suitable for standard handling and storage conditions. Selection should be based on panel design specifications and mounting hole pattern requirements.

Frequently Asked Questions (FAQ)

Q: Can RFSMAA2PEGA be used in place of RFSMAA4PAAC?

A: RFSMAA2PEGA is electrically equivalent to RFSMAA4PAAC but features a two-hole flange mount instead of four-hole. Substitution is possible only if the panel design accommodates two-hole mounting. The electrical performance, frequency response, impedance, and environmental specifications are identical.

Q: What is the primary difference between RFSMAA4PAAC and RFSMAA4PCCA?

A: Both parts are four-hole flange mount SMA connectors with identical electrical and environmental specifications. They are direct mechanical and electrical equivalents. Selection between them may be based on inventory availability or supplier preference.

Q: Are all three parts suitable for high-frequency RF applications?

A: Yes. All three parts support frequencies up to 26.5 GHz with 50 Ohm impedance, making them suitable for microwave and high-frequency RF applications within this frequency range.

Q: Do these connectors require special handling or storage?

A: All parts carry MSL Level 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard component handling and storage practices apply.

Q: Can these connectors be used interchangeably in existing designs?

A: Interchangeability depends on the specific mounting hole pattern in the panel design. RFSMAA4PAAC and RFSMAA4PCCA are fully interchangeable. RFSMAA2PEGA requires a two-hole mounting pattern and cannot be used in designs specifying four-hole mounting without panel modification.

Q: What is the operating temperature range for these connectors?

A: All three parts operate across -65°C to 165°C, providing performance across industrial and extended temperature applications.

Q: Are these parts RoHS compliant?

A: Yes. All three parts are ROHS3 Compliant, meeting current environmental and hazardous substance restrictions.
