Molex 2004880003 Rectangular Connector Plug Housing - Equivalent & Substitute Parts

Part Overview

The Molex 2004880003 is a 3-position rectangular connector plug housing from the Mini-Fit TPA2 200488 series, designed for panel mount and snap-in applications. This component is classified as Active product status with full RoHS3 compliance. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where form factor and performance requirements remain constant.

Substitute Part Grouping Explanation

Substitution of rectangular connector plug housings is determined by strict equivalence across critical electrical and mechanical parameters. The Molex 2004880003 accepts substitution with part number 0039014033 based on the following alignment criteria:

Critical Matching Parameters:

• Connector type (Plug) and contact type (Male Pin) are identical
• Number of positions (3) and pitch (0.165" / 4.20mm) are identical
• Single row configuration matches
• Mounting type (Panel Mount, Snap-In) and fastening type (Locking Ramp) are identical
• Contact termination method (Crimp) is identical
• Operating temperature range (-40°C ~ 105°C) is identical
• RoHS3 compliance and MSL Level 1 certification are equivalent
• ECCN and HTSUS classifications are identical

Non-Critical Variations:

• Insulation material differs (Polyamide PA vs. Polyamide PA66)
• Housing color differs (Black vs. Natural)
• Series designation differs (Mini-Fit TPA2 200488 vs. Mini-Fit Jr 5559)

These variations do not affect functional interchangeability in applications where the connector housing serves its specified electrical and mechanical role.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 2004880003 and Molex 0039014033 maintain Active product status and carry identical regulatory compliance certifications (RoHS3, REACH Unaffected, EAR99). Selection between these parts is based on availability and application-specific requirements:

The 2004880003 (Mini-Fit TPA2 200488 series, Black) is suitable for applications where the original specification is maintained and inventory is available.

The 0039014033 (Mini-Fit Jr 5559 series, Natural) serves as a functional equivalent when the 2004880003 is unavailable. The PA66 insulation material and natural color represent the only substantive differences; these do not compromise electrical or mechanical performance in standard rectangular connector applications.

Both parts are contacts-not-included housings; contact selection must be performed independently according to application requirements.

Frequently Asked Questions (FAQ)

Q: Can Molex 0039014033 be used as a direct replacement for Molex 2004880003?

A: Yes. Both parts share identical electrical and mechanical specifications: 3-position plug housing, 0.165" (4.20mm) pitch, male pin contact type, crimp termination, locking ramp fastening, and -40°C to 105°C operating range. The differences in insulation material (PA vs. PA66) and housing color (Black vs. Natural) do not affect functional interchangeability.

Q: What is the significance of the different insulation materials (PA vs. PA66)?

A: Both polyamide (PA) and polyamide (PA66/Nylon 6/6) are suitable for rectangular connector housings within the specified operating temperature range. PA66 offers slightly enhanced mechanical properties; however, both materials meet the performance requirements for this connector category.

Q: Are contacts included with these connector housings?

A: No. Both the 2004880003 and 0039014033 are housings only. Contacts must be sourced separately and selected according to your application's current rating and contact type requirements.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both parts are RoHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. MSL Level 1 (Unlimited) applies to both, indicating no moisture sensitivity restrictions during storage or handling.

Q: What is the difference between the Mini-Fit TPA2 and Mini-Fit Jr series designations?

A: These are different Molex connector series within the rectangular connector family. Despite the series difference, the 2004880003 and 0039014033 maintain equivalent pitch, position count, mounting configuration, and electrical specifications, making them functionally interchangeable for this housing application.
