P18-8SLF-M Equivalent & Substitute Parts

Part Overview

The P18-8SLF-M is a spade terminal connector manufactured by Panduit Corp, designed for crimp termination of 18-22 AWG wire onto an 8 stud. This non-insulated connector features a serrated termination and tin contact finish on copper material. The part is classified as obsolete, necessitating identification of active equivalent alternatives to maintain supply chain continuity and ensure component availability for new designs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P18-8SLF-M is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Stud/Tab Size: 8 Stud
• Wire Gauge: 18-22 AWG
• Terminal Type: Spring, Snap
• Termination Method: Crimp
• Contact Material: Copper
• Contact Finish: Tin
• Insulation: Non-Insulated
• Tongue Inside Opening: 0.160" (4.06mm)

Allowable Variations:

• Overall length may vary (affects mounting geometry but not electrical function)
• Termination feature design (serrated versus brazed seam) does not affect substitution eligibility
• Product status transition from obsolete to active
• RoHS compliance status upgrade
• Packaging configuration

The substitute part P18-8LF-M maintains all mandatory electrical and mechanical parameters while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The P18-8LF-M is the direct substitute for the obsolete P18-8SLF-M. Selection of the substitute part is based on the following engineering criteria:

Product Status: The P18-8LF-M maintains active product status with current manufacturing support, ensuring long-term availability and supply chain reliability compared to the obsolete P18-8SLF-M.

Compliance Certifications: The P18-8LF-M achieves ROHS3 compliance, meeting current regulatory requirements for restricted substances. Both parts maintain REACH Unaffected and EAR99 export classification status.

Electrical and Mechanical Equivalence: All critical parameters determining functional compatibility are identical between the two parts, including stud size, wire gauge range, contact material and finish, and tongue opening dimensions.

Physical Geometry: The P18-8LF-M features a longer overall length (0.740" versus 0.560"), which reflects design refinement in the Pan-Term® series. This dimensional change does not affect electrical performance or crimp termination compatibility.

Termination Design: The transition from serrated termination to brazed seam construction represents manufacturing process improvement without functional impact on wire retention or electrical conductivity.

Frequently Asked Questions (FAQ)

Q: Can P18-8LF-M be used as a direct replacement for P18-8SLF-M in existing assemblies?

A: Yes. The P18-8LF-M is electrically and mechanically equivalent to the P18-8SLF-M across all critical parameters. Both parts accept 18-22 AWG wire, mount on 8 studs, and feature identical contact material, finish, and tongue opening dimensions. The longer overall length of the P18-8LF-M does not affect functional compatibility.

Q: What is the difference between the serrated termination and brazed seam features?

A: Serrated termination (P18-8SLF-M) and brazed seam (P18-8LF-M) are alternative manufacturing methods for securing the wire crimp. Both methods provide equivalent wire retention and electrical conductivity. The brazed seam design represents a manufacturing refinement in the current product line.

Q: Does the longer length of P18-8LF-M affect installation or performance?

A: The P18-8LF-M is 0.180" (4.58mm) longer overall than the P18-8SLF-M. This dimensional difference reflects design optimization and does not affect electrical performance, crimp compatibility, or stud mounting. Installation procedures remain identical.

Q: Is the P18-8LF-M compliant with current regulatory standards?

A: Yes. The P18-8LF-M is ROHS3 compliant and maintains REACH Unaffected status. Both parts share identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications.

Q: What packaging is available for the P18-8LF-M?

A: The P18-8LF-M is supplied in bulk packaging, with 1166 pieces available in current inventory. The P18-8SLF-M was supplied without specified packaging designation.

Q: Are both parts from the same manufacturer?

A: Yes. Both P18-8SLF-M and P18-8LF-M are manufactured by Panduit Corp and are part of the Pan-Term® series of terminal connectors.
