PH18-8F-Q Equivalent & Substitute Parts

Part Overview

The PH18-8F-Q is a red 8 stud spade terminal connector manufactured by Panduit Corp, designed for crimp termination of 18-22 AWG wire. This component features insulation with heat shrink and is part of the Pan-Term® series. The part is currently listed as obsolete, necessitating identification of active equivalent alternatives that maintain functional compatibility for applications requiring spade terminal connectors with identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PH18-8F-Q is determined by the following critical parameters:

Primary Compatibility Criteria:

• Wire gauge range: 18-22 AWG
• Stud size: 8 Stud
• Termination method: Crimp
• Contact material: Copper with tin finish
• Mounting configuration: Free Hanging (In-Line)
• Color: Red

Secondary Compatibility Considerations:

• Insulation type and material composition
• Overall dimensions (width and length)
• Insulation diameter specifications

Two substitute parts meet the primary compatibility criteria with variations in terminal geometry and insulation specifications:

PH18-8R-Q qualifies as a substitute with identical wire gauge, stud size, termination method, and contact specifications. This part differs in terminal type (circular ring versus spade) and overall dimensions, suitable for applications where ring terminal geometry is functionally equivalent.

PV18-8F-CY qualifies as a substitute with matching terminal type (spade), wire gauge, stud size, and termination method. This part differs in insulation material (vinyl versus polyolefin) and insulation diameter, with active product status and current availability.

Parameter Comparison

Engineering Selection Recommendations

PV18-8F-CY is the primary substitute for direct replacement of the obsolete PH18-8F-Q. Both parts share identical terminal type (spade), stud size (8), wire gauge range (18-22 AWG), and termination method (crimp). The PV18-8F-CY maintains the same outer width dimension (0.320") and color specification. This part is currently active with ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and production applications.

The PV18-8F-CY differs from the main part in insulation material (vinyl versus polyolefin), insulation diameter (0.150" versus 0.170"), and overall length (0.930" versus 1.040"). These dimensional variations require verification of fit within existing connector housings and assembly configurations.

PH18-8R-Q serves as an alternative substitute when circular ring terminal geometry is functionally acceptable. This part maintains identical wire gauge, stud size, contact material, contact finish, and termination method. The PH18-8R-Q is active with ROHS3 compliance. Selection of this part requires confirmation that ring terminal geometry is compatible with the intended application, as it differs fundamentally from the spade terminal configuration of the main part.

Frequently Asked Questions (FAQ)

Q: Can PV18-8F-CY directly replace PH18-8F-Q in existing assemblies?

A: PV18-8F-CY shares the same terminal type (spade), stud size, wire gauge, and termination method as PH18-8F-Q. However, dimensional differences exist: overall length is 0.930" versus 1.040", and insulation diameter is 0.150" versus 0.170". Physical fit within existing connector housings and assembly fixtures must be confirmed before implementation.

Q: What is the functional difference between PH18-8R-Q and PH18-8F-Q?

A: PH18-8R-Q is a circular ring terminal, while PH18-8F-Q is a spade terminal. Both accommodate 18-22 AWG wire on an 8 stud. Ring terminals provide 360-degree contact around the stud, while spade terminals provide contact along a slot. Selection depends on the specific stud configuration and application requirements.

Q: Are both substitute parts compliant with current regulatory standards?

A: Yes. Both PV18-8F-CY and PH18-8R-Q are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What insulation material differences exist between the substitute parts?

A: PH18-8F-Q and PH18-8R-Q use polyolefin insulation, while PV18-8F-CY uses vinyl insulation. Polyolefin provides superior heat shrink recovery characteristics, while vinyl offers different mechanical and thermal properties. Application temperature ranges and environmental exposure conditions determine material suitability.

Q: How do the dimensional specifications affect part selection?

A: The PV18-8F-CY is 0.110" shorter in overall length and has a 0.020" smaller insulation diameter compared to PH18-8F-Q. These differences may affect fit within connector blocks, terminal strips, or custom assemblies. Physical verification is required for applications with tight dimensional tolerances.

Q: Are inventory levels a consideration for part selection?

A: Current inventory shows PV18-8F-CY with 1128 pieces and PH18-8R-Q with 929 pieces available. Both parts maintain active production status, ensuring continued availability for ongoing production requirements.
