Amphenol RF 142146-75 Equivalent & Substitute Parts

Part Overview

The Amphenol RF 142146-75 is an SMB mini coaxial connector jack designed for 75-ohm RF applications. This through-hole, right-angle solder connector features a male pin configuration and is intended for PCB-mounted installations requiring snap-on fastening. The part maintains active product status with 864 units currently in stock.

Substitute parts are identified to provide alternative sourcing options when the primary manufacturer part becomes unavailable, when inventory constraints exist, or when design flexibility permits component standardization across multiple suppliers while maintaining equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Amphenol RF 142146-75 are identified based on strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Impedance: 75 Ohms (exact match required)
• Connector Type: Jack with Male Pin configuration
• Contact and Shield Termination: Solder (both required)

Mechanical Equivalence Criteria:

• Connector Style: SMB mini form factor
• Mounting Configuration: Through Hole, Right Angle orientation
• Fastening Mechanism: Snap-On engagement

Environmental & Compliance Criteria:

• Operating Temperature Range: -65°C to 165°C (minimum)
• RoHS3 Compliance: Required
• REACH Affected Status: Applicable
• Moisture Sensitivity Level: 1 (Unlimited)

Material Specifications:

• Body Material: Brass with Gold finish
• Center Contact: Brass with Gold plating
• Dielectric: Polytetrafluoroethylene (PTFE)

Substitute parts must satisfy all criteria listed above to ensure direct functional and mechanical interchangeability in PCB-mounted RF applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol RF 142146-75 and Samtec Inc. SMB7H-J-P-H-RA-TH1 maintain active product status and satisfy all regulatory compliance requirements for RF coaxial connector applications. Both parts are ROHS3 compliant and REACH affected, meeting current environmental standards for electronic component manufacturing and distribution.

The Samtec SMB7H-J-P-H-RA-TH1 provides an equivalent substitute with identical electrical impedance, mechanical mounting configuration, and material specifications. The substitute part is available in higher inventory quantity (2128 units) compared to the primary part (864 units), offering improved supply chain flexibility.

Selection between these parts should be based on availability requirements, packaging preferences (Amphenol supplied in Bulk; Samtec supplied in Tray), and established supplier relationships within the organization's procurement framework.

Frequently Asked Questions (FAQ)

Q: Can the Samtec SMB7H-J-P-H-RA-TH1 be used as a direct replacement for the Amphenol RF 142146-75?

A: Yes. Both connectors share identical electrical specifications (75-ohm impedance), mechanical configuration (SMB mini, through-hole, right-angle), termination method (solder), and material composition (brass body and center contact with gold plating and PTFE dielectric). Operating temperature ranges and compliance certifications are equivalent.

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

A: The primary differences are manufacturer identity and packaging format. The Amphenol part is supplied in Bulk packaging, while the Samtec equivalent is supplied in Tray packaging. The Samtec part specifies a maximum frequency rating of 4 GHz, which is not provided in the Amphenol specification. Inventory availability differs, with Samtec currently stocking 2128 units versus 864 units for Amphenol.

Q: Are there any compatibility concerns when substituting between these parts?

A: No compatibility concerns exist. Both parts conform to the SMB connector standard with identical jack/male-pin configuration, snap-on fastening, and solder termination. PCB footprints and mounting hole patterns are standardized for SMB connectors in this configuration.

Q: Do both parts meet the same environmental and regulatory standards?

A: Yes. Both parts are ROHS3 compliant, REACH affected, and rated for the same operating temperature range (-65°C to 165°C). Both maintain Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: What should be considered when selecting between these substitute parts?

A: Selection criteria include current inventory availability, packaging requirements for your assembly process, supplier lead times, and cost considerations. Both parts are functionally and mechanically equivalent for 75-ohm RF applications requiring through-hole, right-angle SMB connectors with solder termination.
