RFSMAA2JCCHR SMA Coaxial Connector Equivalent & Substitute Parts

Part Overview

The RFSMAA2JCCHR 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 the primary functional requirements remain constant.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RFSMAA2JCCHR 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
• 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 RFSMAA2JCCHR has two identified substitutes: RFSMAA2JEGDQ and RFSMAA4JCCDQ. The RFSMAA2JEGDQ maintains identical specifications across all parameters. The RFSMAA4JCCDQ differs only in mounting feature configuration (4-hole flange versus 2-hole flange), representing a mechanical variation while maintaining all electrical and environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RFSMAA2JCCHR, RFSMAA2JEGDQ, and RFSMAA4JCCDQ—are active production components manufactured by Bulgin with ROHS3 compliance and unlimited moisture sensitivity rating. Selection between these parts is determined by panel mounting hole configuration requirements.

RFSMAA2JCCHR and RFSMAA2JEGDQ are electrically and mechanically identical, both featuring 2-hole flange mounting. These parts are interchangeable for applications requiring 2-hole panel mount configurations.

RFSMAA4JCCDQ provides the same electrical performance and environmental specifications but incorporates a 4-hole flange mounting feature. This part is selected when panel design requires four-point mechanical fastening instead of two-point fastening.

All three parts maintain identical RF performance characteristics (50 Ohm impedance, 26.5 GHz maximum frequency), thermal operating range (-65°C to 165°C), voltage rating (335 V), and contact material specifications (Beryllium Copper center contact, Stainless Steel body, Polyetherimide dielectric).

Frequently Asked Questions (FAQ)

Q: Can RFSMAA2JEGDQ be used as a direct replacement for RFSMAA2JCCHR?

A: Yes. RFSMAA2JEGDQ is a parametric equivalent with identical electrical, mechanical, and environmental specifications. Both parts feature 2-hole flange mounting and are fully interchangeable in circuit designs.

Q: What is the primary difference between RFSMAA2JCCHR and RFSMAA4JCCDQ?

A: The primary difference is the mounting feature configuration. RFSMAA2JCCHR uses a 2-hole flange, while RFSMAA4JCCDQ uses a 4-hole flange. All electrical and RF performance parameters are identical. Selection depends on panel hole pattern requirements.

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 identical RF applications. The choice between them is based on mechanical mounting requirements, not RF performance.

Q: Do these connectors require special handling or storage?

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 maximum operating temperature for these connectors?

A: All three parts operate across the temperature range of -65°C to 165°C, providing identical thermal performance.

Q: Can these SMA connectors be used interchangeably with other 50 Ohm connectors?

A: These are SMA-style connectors with 50 Ohm impedance. Interchangeability with other connector types depends on the specific connector interface and is outside the scope of these three equivalent parts.

Q: What is the voltage rating for these connectors?

A: All three parts are rated for 335 V, providing identical electrical safety specifications.

Q: How many mating cycles are these connectors rated for?

A: All three parts are rated for 500 mating cycles, indicating identical mechanical durability specifications.
