RFSMAA2JDFHP SMA Coaxial Connector Equivalent & Substitute Parts

Part Overview

The RFSMAA2JDFHP is an SMA connector jack manufactured by Bulgin, designed as a female socket for 50 Ohm RF applications. This panel mount, through-hole solder connector operates across frequencies up to 26.5 GHz and is rated for operating temperatures between -65°C and 165°C. The connector features a two-hole flange mounting configuration with stainless steel construction and beryllium copper center contacts. The part maintains Active product status and is ROHS3 compliant. Equivalent substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part becomes unavailable or when alternative mounting configurations are required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RFSMAA2JDFHP are identified based on strict electrical and mechanical parameter equivalence. All substitute connectors maintain identical specifications across the following critical parameters: SMA connector style, female socket jack type, 50 Ohm impedance, panel mount through-hole configuration, solder termination for both contact and shield, maximum frequency of 26.5 GHz, operating temperature range of -65°C to 165°C, voltage rating of 335 V, mating cycle rating of 500, beryllium copper center contacts, stainless steel body construction, polyetherimide dielectric material, ROHS3 compliance, and MSL 1 rating.

The substitute parts are grouped into two categories based on mounting hole configuration:

Two-Hole Flange Configuration: RFSMAA2JEGDQ maintains identical mounting geometry with a two-hole flange, providing direct mechanical and electrical interchangeability.

Four-Hole Flange Configuration: RFSMAA4JCCDQ features a four-hole flange mounting pattern. This part is electrically equivalent but requires PCB layout modification to accommodate the additional mounting holes. Selection of this variant depends on mechanical mounting requirements and available PCB footprint space.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RFSMAA2JDFHP, RFSMAA2JEGDQ, and RFSMAA4JCCDQ—maintain Active product status and are ROHS3 compliant, ensuring regulatory compliance and long-term availability support.

RFSMAA2JDFHP and RFSMAA2JEGDQ are direct mechanical and electrical equivalents. Selection between these two-hole flange variants depends on inventory availability and procurement lead times. Both parts are suitable for applications where the two-hole mounting configuration is specified in the PCB design.

RFSMAA4JCCDQ is electrically equivalent but features a four-hole flange mounting pattern. This variant is selected when PCB layout accommodates or requires four-hole mounting for enhanced mechanical stability or when design specifications mandate four-point fastening. PCB footprint modification is necessary to implement this variant.

All parts are rated for identical electrical performance across the 50 Ohm impedance, 26.5 GHz maximum frequency, 335 V voltage rating, and -65°C to 165°C operating temperature range. Selection is determined by mechanical mounting requirements and available PCB real estate rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can RFSMAA2JEGDQ be used as a direct replacement for RFSMAA2JDFHP without PCB modification?

A: Yes. RFSMAA2JEGDQ is a direct mechanical and electrical equivalent with identical two-hole flange mounting geometry. No PCB layout changes are required for substitution.

Q: What is the primary difference between RFSMAA2JDFHP and RFSMAA4JCCDQ?

A: The primary difference is the mounting hole configuration. RFSMAA2JDFHP features a two-hole flange, while RFSMAA4JCCDQ features a four-hole flange. All electrical parameters remain identical. PCB footprint modification is required to accommodate the four-hole pattern.

Q: Are all three parts suitable for 26.5 GHz RF applications?

A: Yes. All three parts are rated for maximum frequency of 26.5 GHz and maintain 50 Ohm impedance across the full frequency range.

Q: Do these connectors require special handling or storage conditions?

A: All three parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control measures are required during storage or handling.

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

A: All three parts operate across the temperature range of -65°C to 165°C, supporting both cryogenic and elevated temperature applications.

Q: Are these connectors RoHS compliant?

A: Yes. All three parts are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: Can the four-hole variant RFSMAA4JCCDQ be used in applications designed for the two-hole variant?

A: Electrical compatibility is maintained; however, mechanical compatibility depends on PCB layout. The four-hole mounting pattern requires PCB footprint modification and cannot be directly installed in a two-hole mounting footprint without design changes.
