Key Parameters

Substitute Part Grouping Explanation

The VMB1094 has one identified parametric equivalent: the Amphenol RF 903-402J-51R. Substitution eligibility is determined by strict alignment of the following critical parameters:

• Connector Style: SMB (identical)
• Connector Type: Jack, Male Pin (identical)
• Impedance: 50 Ohms (identical)
• Contact Termination: Solder (identical)
• Shield Termination: Solder (identical)
• Mounting Type: Panel Mount (identical)
• Mounting Feature: Bulkhead - Rear Side Nut (identical)
• Fastening Type: Snap-On (identical)
• Frequency - Max: 4 GHz (identical)
• Number of Ports: 1 (identical)
• Body Finish: Gold (identical)
• Center Contact Plating: Gold (identical)

The 903-402J-51R meets all electrical and mechanical requirements for direct substitution in applications currently using the VMB1094.

Parameter Comparison

Engineering Selection Recommendations

Both the VMB1094 and 903-402J-51R are active production parts with identical core electrical and mechanical specifications for SMB 50-ohm panel-mount solder connectors. Selection between these parts may be based on:

• Inventory availability: VMB1094 has 1033 units in stock; 903-402J-51R has 1180 units in stock
• Compliance requirements: The 903-402J-51R carries explicit ROHS3 compliance and REACH affected status certifications
• Documented performance data: The 903-402J-51R provides specified operating temperature range (-65°C ~ 165°C), mating cycle rating (500), and insertion loss (0.3dB)

Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications and MSL rating (1 - Unlimited).

Frequently Asked Questions (FAQ)

Q: Can the 903-402J-51R be used as a direct replacement for the VMB1094?

A: Yes. Both connectors meet identical specifications for connector style (SMB), type (Jack, Male Pin), impedance (50 Ohms), termination method (Solder), mounting configuration (Panel Mount Bulkhead), and frequency rating (4 GHz). All critical electrical and mechanical parameters align.

Q: What are the key differences between these two parts?

A: The VMB1094 and 903-402J-51R share identical core specifications. The 903-402J-51R provides additional documented specifications including operating temperature range, mating cycle rating, insertion loss, and explicit RoHS3 and REACH compliance statements. The VMB1094 does not specify these parameters.

Q: Are there any packaging or lead-time considerations?

A: Both parts are supplied in bulk packaging. Inventory levels differ: VMB1094 (1033 units) and 903-402J-51R (1180 units). Procurement decisions should account for current stock availability and supply chain requirements.

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

A: Both parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there any compliance or regulatory differences?

A: Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications. The 903-402J-51R explicitly states ROHS3 compliance and REACH affected status. Compliance requirements for specific applications should be verified against end-use regulations.
