Substitute Part Grouping Explanation

Substitution of the obsolete 8-520133-1 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part 3-520133-2 maintains identical specifications for tab width (0.250"), tab thickness (0.032"), wire gauge range (14-16 AWG), terminal gender (Female), terminal type (Angled - 90°, Flag), insulation classification (Fully Insulated), mounting configuration (Free Hanging/Right Angle), termination method (Crimp), contact material (Brass), contact finish (Tin), and insulation diameter (0.185"). Both parts share the same base product number (520133) and series designation (Ultra-Fast), confirming functional and mechanical interchangeability.

The primary distinction between these parts is product status and packaging configuration. The substitute part 3-520133-2 is classified as active and supplied in bulk packaging, whereas the original 8-520133-1 is obsolete and supplied in standard packaging. This substitution enables continued access to functionally identical connectors through current production channels.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 3-520133-2 is the direct functional equivalent for the obsolete 8-520133-1. Selection of the substitute part is based on the following engineering criteria:

Product Status: The substitute part 3-520133-2 maintains active production status, ensuring continued availability and supply chain reliability. The original part 8-520133-1 is classified as obsolete and subject to discontinuation.

Regulatory Compliance: Both parts maintain identical ROHS3 compliance certification and EAR99 export classification, confirming equivalence for regulated applications. Moisture Sensitivity Level (MSL) rating of 1 (Unlimited) is maintained across both parts.

Electrical and Mechanical Specifications: All critical parameters including tab dimensions (0.250" width, 0.032" thickness), wire gauge compatibility (14-16 AWG), terminal configuration (90° angled flag), and contact materials (brass with tin finish) are identical between the original and substitute parts.

Packaging Consideration: The substitute part is supplied in bulk packaging rather than standard packaging. Bulk packaging does not affect connector functionality or performance; it represents a distribution format change only. Organizations requiring standard packaging quantities should consult with the supplier regarding packaging options for part 3-520133-2.

Frequently Asked Questions (FAQ)

Q: Are the 8-520133-1 and 3-520133-2 connectors mechanically interchangeable?

A: Yes. Both connectors share identical tab width (0.250"), tab thickness (0.032"), terminal type (90° angled flag), and mounting configuration (free hanging, right angle). They are direct mechanical substitutes.

Q: Can the 3-520133-2 be used in applications originally designed for the 8-520133-1?

A: Yes. The substitute part maintains identical electrical specifications (14-16 AWG wire gauge, fully insulated, crimp termination) and mechanical dimensions. No design modifications are required.

Q: What is the difference between the two part numbers?

A: The primary differences are product status and packaging. The 8-520133-1 is obsolete and supplied in standard packaging. The 3-520133-2 is active production and supplied in bulk packaging. All functional and electrical specifications are identical.

Q: Does the bulk packaging of the 3-520133-2 affect connector quality or performance?

A: No. Packaging format does not affect connector electrical performance, mechanical dimensions, or material composition. Bulk packaging is a distribution method only.

Q: Are both parts RoHS compliant?

A: Yes. Both the 8-520133-1 and 3-520133-2 are ROHS3 compliant and carry identical regulatory certifications.

Q: What wire gauge range is supported by these connectors?

A: Both connectors support 14-16 AWG wire gauge range with crimp termination.

Q: Can these connectors be used in moisture-sensitive applications?

A: Yes. Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Is the contact material the same between both parts?

A: Yes. Both connectors use brass contacts with tin finish, ensuring identical electrical conductivity and corrosion resistance characteristics.
