Molex 0334828821 Rectangular Connector Plug Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0334828821 is a 16-position rectangular connector plug housing designed for applications requiring male blade contact termination with a 0.138" (3.50mm) pitch. This component is part of the MX150 33482 series and features a sealed design with a locking ramp fastening mechanism. The part is currently in active production status with 958 units in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across connector housings within the same series, allowing for interchangeability in applications where specific color or material specifications do not impose design constraints.

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector plug housings is determined by strict equivalence across the following parameters:

• Connector Type: Must be Plug
• Contact Type: Must be Male Blade
• Number of Positions: Must be 16
• Pitch: Must be 0.138" (3.50mm)
• Number of Rows: Must be 2
• Mounting Type: Must be Free Hanging (In-Line)
• Contact Termination: Must be Crimp
• Fastening Type: Must be Locking Ramp
• Features: Must be Sealed
• Series: Must be MX150 33482

The substitute part Molex 0334828602 maintains all critical electrical and mechanical parameters. Variations in color (Black versus Gray) and insulation material composition do not affect functional interchangeability within the MX150 33482 series architecture.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0334828821 and Molex 0334828602 are active production components within the MX150 33482 series. Selection between these parts is based on application-specific requirements:

Molex 0334828821 (Black, SPS Glass Filled) is the primary specification when color coding or specific material composition is required by design documentation.

Molex 0334828602 (Gray, PA/Nylon and SPS Glass Filled) is functionally equivalent and provides an alternative when the primary part is unavailable. This substitute carries ROHS3 compliance and REACH Unaffected status, with an operating temperature range of -40°C to 150°C. The substitute maintains all critical connector parameters and is suitable for direct replacement in applications where color differentiation is not a functional requirement.

Both parts are classified under ECCN EAR99 and carry MSL Not Applicable status.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0334828602 be used as a direct replacement for the Molex 0334828821?

A: Yes. Both parts maintain identical electrical and mechanical specifications across all critical parameters including connector type, contact configuration, pitch, position count, mounting type, and fastening mechanism. The parts are functionally interchangeable within the MX150 33482 series.

Q: What are the differences between these two connector housings?

A: The primary differences are color (Black versus Gray) and insulation material composition. The 0334828821 uses Syndiotactic Polystyrene (SPS) glass filled material, while the 0334828602 uses Polyamide (PA) Nylon glass filled material combined with Syndiotactic Polystyrene (SPS). The 0334828602 also specifies an operating temperature range of -40°C to 150°C.

Q: Do these connector housings include contacts?

A: No. Both the 0334828821 and 0334828602 are housing-only components. Male blade contacts must be sourced separately and crimped into the housing according to Molex specifications.

Q: Are there packaging differences between these parts?

A: The 0334828821 is supplied in standard packaging, while the 0334828602 is supplied in bulk packaging. Inventory availability differs, with 1754 units of the 0334828602 currently in stock compared to 958 units of the 0334828821.

Q: What is the pitch specification and why is it important?

A: The pitch is 0.138" (3.50mm), which defines the center-to-center distance between adjacent contact positions. This specification must remain constant for interchangeability and determines compatibility with mating connector receptacles.

Q: Can color selection affect connector performance?

A: Color is a visual identifier and does not affect electrical or mechanical performance. Selection between black and gray housings is based on application documentation, assembly traceability requirements, or design specifications rather than functional capability.
