Substitute Part Grouping Explanation

Substitution of the R300124403 with CONREVSMA002-G is valid based on strict electrical and mechanical parameter equivalence. Both components share identical specifications across all critical substitution criteria: RP-SMA connector style, receptacle configuration with male pin, 50-ohm impedance, through-hole right-angle mounting, solder termination for both contact and shield, maximum frequency of 12.4 GHz, operating temperature range of -65°C to 165°C, threaded fastening, single port configuration, and 500 mating cycles. The dielectric material (PTFE), body material (brass), body finish (gold), and center contact plating (gold) are identical across both parts. These parameters define the functional and physical compatibility required for direct substitution in RF coaxial connector applications.

Parameter Comparison

Engineering Selection Recommendations

Both R300124403 and CONREVSMA002-G are classified as Active products, confirming ongoing manufacturer support and availability. Selection between these components should be based on supply chain requirements and inventory status. The R300124403 maintains 1,096 units in current stock, while CONREVSMA002-G provides 7,685 units in inventory. CONREVSMA002-G carries RoHS Compliant certification and REACH Unaffected status, with Moisture Sensitivity Level (MSL) rated at 1 (Unlimited), indicating superior handling flexibility compared to the R300124403 which lists MSL as Not Applicable. Both components share identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications, ensuring equivalent regulatory treatment. The center contact material differs between manufacturers—R300124403 uses brass while CONREVSMA002-G uses beryllium copper—however this material variation does not affect the electrical or mechanical substitution criteria for the specified application parameters.

Frequently Asked Questions (FAQ)

Q: Can CONREVSMA002-G directly replace R300124403 in existing designs?

A: Yes. Both components meet identical specifications for RP-SMA receptacle configuration, 50-ohm impedance, through-hole right-angle mounting, solder termination, 12.4 GHz maximum frequency, -65°C to 165°C operating temperature range, and 500 mating cycles. No design modifications are required.

Q: What are the key electrical parameters that define substitution compatibility?

A: Connector style (RP-SMA), connector type (receptacle with male pin), impedance (50 ohms), frequency rating (12.4 GHz maximum), and operating temperature range (-65°C to 165°C) are the primary electrical parameters. Both parts are identical across these criteria.

Q: Are there mechanical differences between these connectors?

A: Both connectors share identical mechanical specifications: through-hole right-angle mounting, threaded fastening, single port configuration, and 500 mating cycles. Physical form factor and PCB interface are equivalent.

Q: What is the significance of the center contact material difference?

A: R300124403 uses brass center contacts while CONREVSMA002-G uses beryllium copper. Both materials provide adequate conductivity and durability for the specified 50-ohm RF application. This material variation does not affect substitution eligibility based on the provided electrical and mechanical parameters.

Q: How do the compliance certifications compare?

A: Both components carry identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications. CONREVSMA002-G includes RoHS Compliant certification and REACH Unaffected status. Both are classified as Active products with ongoing manufacturer support.

Q: What packaging considerations apply to these connectors?

A: Both components are supplied in bulk packaging. CONREVSMA002-G specifies MSL 1 (Unlimited), allowing unrestricted handling and storage conditions. R300124403 lists MSL as Not Applicable. Standard moisture control practices are recommended for both components during storage and assembly.

Q: Are there any frequency or temperature limitations that would restrict substitution?

A: No. Both connectors operate identically across the full frequency range up to 12.4 GHz and maintain performance across the complete temperature range of -65°C to 165°C. No operational restrictions apply to substitution.
