Substitute Part Grouping Explanation

Substitute parts for the PRF92-P-C-EE-118-SD are identified based on strict electrical and mechanical parameter alignment. The substitution criteria are:

Primary Substitution Parameters:

• Connector Style: 2.92mm
• Connector Type: Plug, Male Pin
• Impedance: 50 Ohms
• Contact Termination: Solder
• Shield Termination: Solder
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Threaded
• Frequency - Max: 40 GHz
• Number of Ports: 1
• Body Material: Stainless Steel
• RoHS Status: ROHS3 Compliant

All identified substitutes meet these core parameters. Variations in secondary parameters such as dielectric material, center contact plating, and operating temperature specifications do not preclude substitution where the primary electrical and mechanical requirements are satisfied.

Parameter Comparison

Engineering Selection Recommendations

PRF92-P-C-EE-085A-SD (Samtec Inc.): This part is a direct parametric equivalent to the PRF92-P-C-EE-118-SD, manufactured by the same supplier. Both parts share identical electrical specifications, materials, and compliance certifications. The PRF92-P-C-EE-085A-SD offers higher inventory availability (1036 units versus 642 units), making it suitable for applications where supply continuity is a priority. Selection between these two Samtec variants should be based on cable length requirements or specific design documentation references.

RF292APG (Bulgin): This part meets all primary electrical and mechanical substitution criteria and is ROHS3 compliant with EAR99 export classification. The RF292APG features a polyetherimide (PEI) dielectric material in place of PTFE, with documented operating temperature range (-65°C to 165°C) and mating cycle rating (500 cycles). This part is suitable for applications where the specified operating temperature and mechanical durability parameters are compatible with system requirements. Inventory availability is comparable to the Samtec alternatives (1029 units in stock).

All three parts are active products with current production status and meet regulatory compliance requirements for the specified application category.

Frequently Asked Questions (FAQ)

Q: Can PRF92-P-C-EE-085A-SD be used interchangeably with PRF92-P-C-EE-118-SD?

A: Yes. Both parts are manufactured by Samtec Inc. and share identical electrical specifications, impedance (50 Ohms), frequency rating (40 GHz), connector style (2.92mm), termination method (solder), and compliance certifications (ROHS3). The primary difference is inventory availability. Selection should be based on design documentation or cable length specifications if applicable.

Q: What is the key difference between the Samtec PRF92 series and the Bulgin RF292APG?

A: The primary electrical and mechanical parameters are equivalent. The RF292APG differs in dielectric material (PEI versus PTFE) and includes documented operating temperature (-65°C to 165°C) and mating cycle (500) specifications. These differences do not affect substitution eligibility for 50-ohm, 40 GHz 2.92mm solder-terminated applications.

Q: Are all three parts ROHS3 compliant?

A: Yes. PRF92-P-C-EE-118-SD, PRF92-P-C-EE-085A-SD, and RF292APG are all ROHS3 compliant and carry EAR99 export classification.

Q: What is the significance of the dielectric material difference (PTFE versus PEI)?

A: Both PTFE and PEI are suitable dielectric materials for 50-ohm RF connectors operating at frequencies up to 40 GHz. The choice between them is determined by application-specific requirements such as operating temperature range, mechanical durability, and environmental exposure. The RF292APG with PEI dielectric includes a documented operating temperature range of -65°C to 165°C.

Q: How should I select between these three parts for procurement?

A: Selection should be based on: (1) design documentation or engineering specification references; (2) inventory availability and lead time requirements; (3) supplier preference or qualification status; (4) operating environment specifications (temperature, mating cycles); (5) cost considerations. All three parts satisfy the core electrical and mechanical requirements for 2.92mm, 50-ohm, solder-terminated RF cable connector applications.

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

A: No compatibility concerns exist at the connector interface level. All three parts feature identical 2.92mm connector geometry, male pin configuration, threaded fastening, and 50-ohm impedance. Substitution is mechanically and electrically compatible. System-level validation should confirm that any differences in secondary specifications (dielectric material, operating temperature range) align with application requirements.
