RFSMAA2JCCHP SMA Coaxial Connector Equivalent & Substitute Parts

Part Overview

The RFSMAA2JCCHP is an SMA connector jack (female socket) manufactured by Bulgin, designed for 50 Ohm RF applications requiring panel mount through-hole solder termination. This connector operates across frequencies up to 26.5 GHz and is rated for operating temperatures between -65°C and 165°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent electrical and mechanical parameters are maintained, allowing for component interchangeability in circuit designs where specific mounting configurations or inventory availability require alternative part numbers.

Substitute Part Grouping Explanation

Substitute parts for the RFSMAA2JCCHP are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

Electrical Parameters (Must Match):

• Connector Style: SMA
• Connector Type: Jack, Female Socket
• Impedance: 50 Ohms
• Frequency - Max: 26.5 GHz
• Voltage Rating: 335 V
• Mating Cycles: 500

Mechanical Parameters (Must Match):

• Mounting Type: Panel Mount, Through Hole
• Mounting Feature: Flange
• Contact Termination: Solder
• Shield Termination: Solder
• Center Contact Material: Beryllium Copper
• Body Material: Stainless Steel
• Dielectric Material: Polyetherimide (PEI)

Environmental & Compliance Parameters (Must Match):

• Operating Temperature Range: -65°C ~ 165°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute parts RFSMAA2JEGDQ and RFSMAA4JCCDQ maintain all electrical and environmental specifications. The primary distinction between RFSMAA2JCCHP and RFSMAA2JEGDQ is internal construction detail, while RFSMAA4JCCDQ differs in the number of mounting holes (4-hole versus 2-hole configuration), which affects panel layout and mechanical mounting only.

Parameter Comparison

Engineering Selection Recommendations

All three parts (RFSMAA2JCCHP, RFSMAA2JEGDQ, and RFSMAA4JCCDQ) are active production components with ROHS3 compliance and identical electrical performance specifications. Selection between these parts is determined by mechanical mounting requirements:

RFSMAA2JCCHP and RFSMAA2JEGDQ are functionally equivalent with 2-hole flange mounting configurations. These parts are suitable for applications where panel layout accommodates 2-hole mounting geometry.

RFSMAA4JCCDQ provides a 4-hole flange mounting configuration while maintaining all electrical and environmental specifications. This variant is selected when panel design requires four mounting points for enhanced mechanical stability or when existing panel tooling specifies 4-hole mounting.

All parts maintain identical RF performance, impedance characteristics, temperature ratings, and compliance certifications. Selection is based solely on mechanical mounting hole configuration and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can RFSMAA2JEGDQ be used as a direct replacement for RFSMAA2JCCHP?

A: Yes. Both parts are electrically and mechanically equivalent with identical 2-hole flange mounting configurations. All RF performance parameters, impedance, frequency response, temperature ratings, and compliance certifications are identical.

Q: What is the primary difference between RFSMAA2JCCHP and RFSMAA4JCCDQ?

A: The primary difference is the mounting hole configuration. RFSMAA2JCCHP features 2-hole flange mounting, while RFSMAA4JCCDQ features 4-hole flange mounting. All electrical specifications, RF performance, and environmental ratings are identical. Selection depends on panel layout and mechanical mounting requirements.

Q: Are these connectors suitable for high-frequency applications?

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

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 environments.

Q: Are these parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant and carry unlimited moisture sensitivity level (MSL 1), suitable for standard storage and handling conditions.

Q: Can I interchange these parts in an existing design?

A: RFSMAA2JCCHP and RFSMAA2JEGDQ are directly interchangeable. RFSMAA4JCCDQ requires panel modification to accommodate the 4-hole mounting configuration. Electrical performance and RF characteristics remain identical across all three parts.

Q: What is the mating cycle rating for these connectors?

A: All three parts are rated for 500 mating cycles, indicating the expected number of connect/disconnect operations before performance degradation.
