Key Parameters

Substitute Part Grouping Explanation

Substitution of the PV18-8FX-M is determined by strict equivalence across the following critical parameters:

• Wire Gauge Compatibility: 18-22 AWG requirement must be maintained
• Stud Size: 8 stud configuration is mandatory for mechanical fit
• Termination Method: Crimp termination only
• Insulation Status: Insulated construction required
• Color Specification: Red insulation
• Contact Material: Copper contact material
• Mounting Configuration: Free hanging in-line mounting

The Molex 0191980004 satisfies all mandatory substitution criteria. Both components are standard terminal types with identical wire gauge ratings, stud sizes, termination methods, and insulation properties. The substitute part is currently active in production status, providing continuity for applications previously using the obsolete PV18-8FX-M.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0191980004 is the qualified substitute for the obsolete Panduit PV18-8FX-M based on the following factors:

Functional Equivalence: Both components meet identical electrical and mechanical specifications for 18-22 AWG wire termination onto 8 studs with crimp attachment. The dimensional variations (width difference of 0.004", length difference of 0.025", and tongue opening difference of 0.003") fall within acceptable tolerances for standard spade terminal applications.

Product Status: The substitute part maintains active production status, ensuring long-term availability and supply chain continuity. The original PV18-8FX-M is obsolete and no longer manufactured.

Compliance: The Molex 0191980004 carries ROHS3 compliance certification and REACH unaffected status, meeting current regulatory requirements. The original part lists RoHS status as not applicable due to its obsolete classification.

Material Composition: The substitute employs polyamide nylon insulation in place of vinyl, providing equivalent electrical and mechanical performance with enhanced durability characteristics. Both components utilize copper contacts with tin-based finishes suitable for standard electrical applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0191980004 directly replace the Panduit PV18-8FX-M in existing applications?

A: Yes. Both components are functionally equivalent for 18-22 AWG wire termination onto 8 studs. The dimensional differences are minor and do not affect mechanical fit or electrical performance in standard applications.

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

A: The Molex substitute is 0.025" longer overall (0.915" vs 0.890"), 0.004" narrower at outer edges (0.316" vs 0.320"), and has a tongue opening 0.003" larger (0.173" vs 0.170"). These variations are within normal manufacturing tolerances for spade terminal connectors.

Q: Why is the insulation material different between the two parts?

A: The Panduit PV18-8FX-M uses vinyl insulation, while the Molex 0191980004 uses polyamide nylon. Both materials provide equivalent electrical insulation and mechanical protection for 18-22 AWG applications. Polyamide nylon offers improved durability and is standard in current production spade terminals.

Q: Does the contact finish difference affect compatibility?

A: No. Both parts use tin-based contact finishes on copper substrates. The Panduit uses tin plating while the Molex uses electro-tin plating. Both finishes provide equivalent corrosion resistance and electrical conductivity for standard applications.

Q: What is the packaging difference between these parts?

A: The Panduit PV18-8FX-M is supplied in standard packaging, while the Molex 0191980004 is supplied in bulk packaging. Bulk packaging does not affect component performance or compatibility.

Q: Are there any compliance or certification differences?

A: The Molex 0191980004 is ROHS3 compliant and REACH unaffected, meeting current environmental regulations. The Panduit PV18-8FX-M lists RoHS status as not applicable due to its obsolete status. For new designs or applications requiring regulatory compliance, the Molex substitute is the appropriate selection.

Q: Can both parts be used interchangeably in the same circuit board or assembly?

A: Yes. The functional and dimensional equivalence of these components allows interchangeable use in applications designed for 18-22 AWG spade terminals on 8 studs. The minor dimensional variations do not create compatibility issues in standard mounting configurations.
