Substitute Part Grouping Explanation

Substitute parts for the Molex 0194190021 are identified based on strict parametric equivalence. The following criteria determine substitutability:

Critical Parameters for Substitution:

• Connector type (Plug)
• Contact type (Male Blade)
• Number of positions (16)
• Pitch specification (0.230" / 5.84mm)
• Number of rows (2)
• Row spacing (0.236" / 6.00mm)
• Mounting type (Free Hanging In-Line)
• Contact termination method (Crimp)
• Fastening type (Locking Ramp)
• Environmental rating (IP67)
• Operating temperature range (-40°C ~ 120°C)
• RoHS compliance status (ROHS3)

The substitute part 0194190020 maintains identical specifications across all critical parameters, confirming full functional and mechanical interchangeability within the MX150L series.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0194190021 and 0194190020 are active production parts with full ROHS3 compliance and identical parametric specifications. Selection between these parts should be based on inventory availability and supply chain requirements. The substitute part 0194190020 carries higher inventory levels (5144 pcs vs. 947 pcs), making it suitable for applications where supply continuity is a priority. Both parts maintain equivalent environmental ratings (IP67), temperature performance (-40°C ~ 120°C), and moisture sensitivity classifications (MSL 1). No technical differentiation exists between these components for standard applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0194190020 be used as a direct replacement for the 0194190021?

A: Yes. Both parts are identical in all critical electrical and mechanical parameters, including connector type, position count, pitch, row configuration, mounting method, contact termination, fastening mechanism, and environmental rating. Direct substitution is supported without design modification.

Q: What are the key parameters that determine substitutability for this connector housing?

A: Substitutability is determined by: connector type (Plug), contact type (Male Blade), 16-position configuration, 0.230" pitch, 2-row layout with 0.236" row spacing, free-hanging in-line mounting, crimp termination, locking ramp fastening, IP67 environmental sealing, and -40°C to 120°C operating range.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance status, MSL 1 rating, and active product status. Both are manufactured by Molex within the MX150L series.

Q: What is the significance of the MSL 1 rating?

A: MSL 1 indicates unlimited shelf life with no moisture sensitivity restrictions. These connector housings do not require special moisture-controlled storage or handling procedures.

Q: Can these housings be used interchangeably in existing assemblies?

A: Yes. The identical pitch, row spacing, mounting type, and fastening mechanism ensure mechanical and functional interchangeability in any application designed for either part number.
