RF55-30H-T-00-50-G-SH Equivalent & Substitute Parts

Part Overview

The RF55-30H-T-00-50-G-SH is an SMB Fakra connector plug manufactured by Adam Tech, designed for 50 Ohm coaxial applications with vertical mounting orientation. This through-hole solder termination connector operates across RF frequencies up to 4 GHz and is classified as an active product with ROHS3 compliance. Substitute parts become necessary when vertical mounting geometry conflicts with PCB layout requirements, when specific connector orientation variants are unavailable, or when inventory constraints necessitate alternative sourcing from the same product family.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for RF55-30H-T-00-50-G-SH is determined by strict equivalence across the following critical parameters:

• Connector Family: SMB Fakra plug configuration
• Electrical Impedance: 50 Ohms (mandatory for RF signal integrity)
• Termination Method: Solder contact and shield termination
• Mounting Technology: Through-hole PCB mounting
• Frequency Rating: 4 GHz maximum operating frequency
• Material Specifications: Brass body with gold finish, PTFE dielectric
• Compliance: ROHS3 and REACH Unaffected status
• Environmental Rating: -40°C to 85°C operating range, MSL 1

The substitute parts RF55-25H-T-00-50-G-SH and RF55-28H-T-00-50-G-SH maintain electrical and material equivalence. The primary distinction lies in connector orientation: RF55-30H features vertical mounting geometry, while RF55-25H provides straight orientation and RF55-28H offers alternative PCB mounting configuration. All three parts share identical electrical performance, impedance characteristics, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

All three connector variants maintain active product status with identical ROHS3 and REACH compliance certifications. Selection between RF55-30H-T-00-50-G-SH, RF55-25H-T-00-50-G-SH, and RF55-28H-T-00-50-G-SH is determined exclusively by PCB layout geometry and mounting orientation requirements. The RF55-30H vertical configuration suits applications requiring perpendicular connector orientation relative to the PCB plane. The RF55-25H straight configuration accommodates inline PCB mounting. The RF55-28H variant provides alternative mounting geometry for specific PCB design constraints. Electrical performance, impedance matching, and frequency response remain equivalent across all three options. Inventory availability shows RF55-28H-T-00-50-G-SH at 1626 units, RF55-25H-T-00-50-G-SH at 772 units, and RF55-30H-T-00-50-G-SH at 758 units.

Frequently Asked Questions (FAQ)

Q: Can RF55-25H-T-00-50-G-SH replace RF55-30H-T-00-50-G-SH in my application?

A: Electrical substitution is valid. Both connectors maintain 50 Ohm impedance, identical frequency response to 4 GHz, and equivalent material specifications. The primary difference is connector orientation: RF55-30H provides vertical mounting while RF55-25H provides straight mounting. Substitution is feasible only if PCB layout accommodates the straight connector geometry.

Q: What is the difference between these three SMB Fakra connectors?

A: RF55-30H-T-00-50-G-SH, RF55-25H-T-00-50-G-SH, and RF55-28H-T-00-50-G-SH are electrically equivalent 50 Ohm SMB Fakra male plug connectors with solder termination. The designations 30H, 25H, and 28H indicate distinct mounting orientations and PCB interface geometries. All three share identical electrical performance, frequency rating, operating temperature range, and compliance certifications.

Q: Are these connectors interchangeable for RF signal integrity?

A: Yes, from an RF perspective. All three connectors maintain 50 Ohm characteristic impedance, support frequencies to 4 GHz, and utilize identical dielectric materials (PTFE) and contact plating (gold). Signal integrity and impedance matching are equivalent. Interchangeability is limited only by physical mounting geometry constraints on the PCB.

Q: What compliance certifications apply to all substitute options?

A: All three connectors carry ROHS3 compliance and REACH Unaffected status. Moisture sensitivity level is rated at MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. ECCN classification is EAR99 for all variants.

Q: Can I use RF55-28H-T-00-50-G-SH as a direct replacement?

A: RF55-28H-T-00-50-G-SH is electrically and materially equivalent to RF55-30H-T-00-50-G-SH. Substitution is valid provided the PCB mounting footprint and connector orientation geometry align with the RF55-28H configuration. Verify physical mounting compatibility before implementation.
