PV18-8R-C Ring Terminal Connector Equivalent & Substitute Parts

Part Overview

The PV18-8R-C is an insulated ring terminal connector manufactured by Panduit Corp, designed for 18-22 AWG wire gauges with an 8 stud circular configuration. This component features a brazed seam construction with tin-plated copper contacts and vinyl insulation. The part is classified as obsolete, necessitating identification of active equivalent alternatives for continued procurement and system maintenance.

Key Parameters

Parameter	Value
Terminal Type	Circular
Stud/Tab Size	8 Stud
Wire Gauge	18-22 AWG
Termination Method	Crimp
Insulation Type	Insulated
Contact Material	Copper

Mounting Type	Free Hanging (In-Line)

Substitute Part Grouping Explanation

Substitution eligibility for the PV18-8R-C is determined by the following critical parameters: terminal type (circular), stud size (8 stud), wire gauge compatibility, termination method (crimp), contact material (copper), and contact finish (tin). Parts meeting these core electrical and mechanical specifications are classified as direct or similar substitutes.

Direct Substitute: PV18-8R-CY maintains identical electrical and mechanical specifications to the main part, with the primary distinction being packaging format and active product status.

Similar Substitute: 2-34148-1 (TE Connectivity) accommodates an expanded wire gauge range (16-22 AWG versus 18-22 AWG) and exhibits minor dimensional variations within acceptable tolerance ranges for the 8 stud circular configuration. This part qualifies as a functional substitute despite wire gauge and dimensional differences.

Engineering Selection Recommendations

PV18-8R-CY is the primary substitute for the obsolete PV18-8R-C. This part is manufactured by the same supplier (Panduit Corp) and maintains identical electrical and mechanical specifications. The PV18-8R-CY carries active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. Packaging differs (bulk versus original format), but electrical performance and physical dimensions remain equivalent.

2-34148-1 (TE Connectivity) serves as a secondary substitute option. This part accommodates the specified 18-22 AWG range within its broader 16-22 AWG capability and maintains the 8 stud circular configuration with tin-plated copper contacts. Minor dimensional variations exist: thickness tolerance of 0.001" (0.02mm), width tolerance of 0.002" (0.05mm), and length reduction of 0.054" (1.37mm). Insulation diameter range (0.105" ~ 0.140") encompasses the original 0.150" specification within acceptable mechanical tolerance. The 2-34148-1 is supplied in cut tape packaging and carries ROHS3 compliance with higher inventory availability.

Frequently Asked Questions (FAQ)

Q: Can PV18-8R-CY be used as a direct replacement for PV18-8R-C?

A: Yes. PV18-8R-CY is a direct electrical and mechanical equivalent. Both parts feature identical wire gauge (18-22 AWG), stud size (8), terminal type (circular), contact material (copper), contact finish (tin), and overall dimensions. The primary difference is packaging format and active product status of the substitute.

Q: What are the limitations of using 2-34148-1 as a substitute?

A: The 2-34148-1 accommodates wire gauges from 16-22 AWG, which includes the original 18-22 AWG specification. Dimensional variations include 0.054" shorter overall length and insulation diameter range of 0.105" ~ 0.140" versus the original 0.150". These variations remain within acceptable mechanical tolerances for the 8 stud circular configuration. The part is supplied in cut tape packaging rather than bulk format.

Q: Are there compliance differences between the main part and substitutes?

A: The PV18-8R-C lists RoHS status as not applicable. Both PV18-8R-CY and 2-34148-1 are ROHS3 compliant, indicating updated manufacturing processes and material composition. This compliance enhancement does not affect electrical or mechanical performance for the specified application.

Q: How do insulation material differences affect substitution?

A: The PV18-8R-C and PV18-8R-CY both use vinyl insulation. The 2-34148-1 uses Poly-Vinyl Chloride (PVC), which is chemically equivalent to vinyl and provides equivalent electrical insulation properties for this terminal application.

Q: What packaging options are available for substitutes?

A: PV18-8R-CY is supplied in bulk packaging. The 2-34148-1 is supplied in cut tape (CT) format. Packaging selection depends on procurement volume and assembly process requirements.

Q: Are dimensional tolerances critical for this application?

A: The 8 stud circular configuration accommodates the minor dimensional variations present in the substitute parts. The 2-34148-1 exhibits maximum dimensional variance of 0.054" in overall length and 0.002" in width, which remain within standard mechanical tolerances for free-hanging in-line terminal applications.
