Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector housings within the MX150 33482 series is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Connector Type (Plug)
• Contact Type (Male Blade)
• Number of Positions (12)
• Pitch (0.138" / 3.50mm)
• Number of Rows (2)
• Mounting Type (Free Hanging In-Line)
• Contact Termination (Crimp)
• Fastening Type (Locking Ramp)
• Features (Sealed)
• Series (MX150 33482)

The substitute parts 0334826202 and 0334826262 maintain full electrical and mechanical compatibility with the main part 0334826249 across all mandatory parameters. Variations in color (Black versus Gray) and insulation material composition do not affect functional interchangeability within the connector housing category, as these are cosmetic and material property differences that do not impact contact engagement, sealing performance, or mechanical fit.

Parameter Comparison

Engineering Selection Recommendations

All three parts—0334826249, 0334826202, and 0334826262—are classified as Active products and are suitable for direct substitution based on electrical and mechanical parameter equivalence. The substitute parts 0334826202 and 0334826262 provide additional compliance documentation, with both rated ROHS3 Compliant and REACH Unaffected, offering enhanced regulatory traceability for applications requiring formal compliance certification.

The operating temperature specification of -40°C to 150°C is documented for substitute parts 0334826202 and 0334826262, providing explicit thermal performance data for temperature-sensitive applications. The main part 0334826249 does not include an operating temperature specification in the provided data.

Selection between the three parts should be based on:

1. Color Requirements: Black housing (0334826249) versus Gray housing (0334826202, 0334826262)
2. Compliance Documentation: Substitute parts provide explicit RoHS3 and REACH compliance statements
3. Inventory Availability: Main part has 1,126 units; 0334826202 has 2,392 units; 0334826262 has 1,631 units
4. Material Composition: Main part specifies SPS only; substitute parts specify PA/Nylon with SPS

All parts are packaged in Bulk format and are suitable for crimp termination with male blade contacts in 12-position, 2-row configurations.

Frequently Asked Questions (FAQ)

Q: Can 0334826202 or 0334826262 be used as direct replacements for 0334826249?

A: Yes. Both substitute parts maintain full electrical and mechanical compatibility across all critical parameters: 12 positions, 3.50mm pitch, 2-row configuration, male blade contacts, crimp termination, locking ramp fastening, and sealed construction. The parts are functionally interchangeable within the MX150 33482 series.

Q: What is the difference between the three parts?

A: The primary differences are color (Black for 0334826249; Gray for 0334826202 and 0334826262) and insulation material composition. Substitute parts 0334826202 and 0334826262 include explicit operating temperature specifications (-40°C to 150°C) and formal RoHS3/REACH compliance documentation not provided for the main part.

Q: Are there any compatibility issues when substituting between these parts?

A: No compatibility issues exist. All three parts share identical connector type, contact type, position count, pitch, row configuration, mounting type, termination method, and fastening mechanism. Contacts are not included with any of these housing parts and must be sourced separately.

Q: Does the color difference affect electrical performance?

A: No. Color is a cosmetic attribute and does not affect electrical performance, contact engagement, sealing integrity, or mechanical fit.

Q: What is the significance of the different insulation materials?

A: Both material compositions (SPS for the main part; PA/Nylon with SPS for substitutes) are glass-filled and provide sealed construction. The material difference does not affect functional interchangeability for standard connector housing applications.

Q: Are these parts suitable for high-temperature applications?

A: Substitute parts 0334826202 and 0334826262 are rated for -40°C to 150°C operation. The main part 0334826249 does not include an operating temperature specification in the provided documentation.

Q: What is the MSL rating, and why does it differ?

A: The main part 0334826249 is rated MSL Not Applicable, while substitute parts are rated MSL 1 (Unlimited). MSL 1 indicates minimal moisture sensitivity and unlimited shelf life under standard storage conditions. This difference reflects different manufacturing or documentation standards but does not affect functional performance.

Q: Are contacts included with these connector housings?

A: No. All three parts are connector housings only. Male blade contacts must be sourced and crimped separately for assembly.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the design does not specify a particular color or material requirement. All three parts are mechanically and electrically equivalent for the connector housing function.
