Key Parameters

Substitute Part Grouping Explanation

The substitute part 174933-1 is classified as a parametric equivalent based on the following criteria:

Matching Parameters (Substitution Basis):

• Identical manufacturer and series (TE Connectivity Multi-Lock)
• Identical connector type and contact type (Receptacle, Tab)
• Identical number of positions and row configuration (12 positions, 2 rows)
• Identical row spacing (0.232" / 5.90mm)
• Identical mounting type (Free Hanging In-Line)
• Identical contact termination method (Crimp)
• Identical insulation material (Polybutylene Terephthalate PBT)
• Identical operating temperature range (-30°C ~ 105°C)
• Identical moisture sensitivity level (MSL 1 Unlimited)
• Identical base product number (174933)

Differing Parameters (Non-Critical Variations):

• Color: Black (174933-2) versus White (174933-1)
• Packaging: Bulk (174933-2) versus Tray (174933-1)
• RoHS Status: RoHS Compliant (174933-2) versus ROHS3 Compliant (174933-1)

The color and packaging variations do not affect electrical or mechanical compatibility. Both parts maintain identical functional specifications and environmental ratings.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (174933-2): The 174933-2 is suitable for applications where black housing color is specified or preferred. This part maintains Active product status with RoHS compliance certification and unlimited moisture sensitivity rating, confirming suitability for standard industrial and commercial applications.

Substitute Part Selection (174933-1): The 174933-1 provides functional equivalence with identical electrical and mechanical specifications. The white housing color and tray packaging represent the primary differentiators. This part carries ROHS3 compliance, which exceeds the baseline RoHS requirement. Selection of this substitute is appropriate when tray packaging is preferred for automated assembly processes or when white housing color meets application requirements.

Compliance Considerations: Both parts maintain compliance with RoHS directives and carry unlimited moisture sensitivity ratings, confirming suitability for equivalent environmental conditions. The ROHS3 certification of the substitute part indicates enhanced compliance status without introducing incompatibility.

Frequently Asked Questions (FAQ)

Q: Can 174933-1 be used as a direct replacement for 174933-2?

A: Yes. The 174933-1 is a parametric equivalent with identical electrical and mechanical specifications. All critical parameters including connector type, position count, row spacing, mounting configuration, contact termination, insulation material, and operating temperature range are identical. The parts are functionally interchangeable.

Q: What is the significance of the color difference between these parts?

A: Color is a cosmetic variation that does not affect electrical performance or mechanical compatibility. Selection between black (174933-2) and white (174933-1) housings depends on application aesthetics or assembly line color-coding requirements. Both colors utilize identical PBT insulation material and maintain the same environmental ratings.

Q: How does packaging type affect part selection?

A: The 174933-2 is supplied in bulk packaging, while the 174933-1 is supplied in tray packaging. Tray packaging is typically preferred for automated pick-and-place assembly systems, while bulk packaging may be suitable for manual assembly or kitting operations. Packaging selection does not affect component functionality or compatibility.

Q: Are both parts RoHS compliant?

A: Yes. The 174933-2 carries RoHS compliance certification, and the 174933-1 carries ROHS3 compliance certification. Both certifications confirm lead-free construction and compliance with hazardous substance restrictions. ROHS3 represents an enhanced compliance level without introducing incompatibility.

Q: What does Moisture Sensitivity Level 1 (Unlimited) mean?

A: MSL 1 (Unlimited) indicates that the component has no moisture sensitivity restrictions. The part does not require special moisture-controlled storage, handling, or baking procedures prior to assembly. Both the main part and substitute maintain this rating.

Q: Can these parts be used in the same connector assembly?

A: Yes. Both parts are from the TE Connectivity Multi-Lock series with identical position counts, row spacing, and mounting configurations. They are mechanically and electrically compatible within the same connector assembly design.

Q: What is the operating temperature range for these parts?

A: Both parts operate across the temperature range of -30°C to 105°C. This range is suitable for standard industrial and commercial applications. No temperature-related limitations exist between the main part and substitute.
