Substitute Part Grouping Explanation

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

Position Count & Pitch Configuration: The substitute part must maintain identical 10-position count and 0.165" (4.20mm) pitch specification to ensure mechanical and electrical compatibility with mating receptacle housings and contact arrangements.

Connector Geometry & Mounting: Both the main part and substitute must share identical row configuration (2 rows), row spacing (0.165"), mounting methodology (Panel Mount, Snap-In), and fastening mechanism (Locking Ramp) to guarantee physical interchangeability in circuit board and panel assemblies.

Material & Environmental Specifications: Insulation material (Polyamide PA66, Nylon 6/6), operating temperature range (-40°C ~ 105°C), and sealed feature classification must remain constant to preserve environmental protection and thermal performance characteristics.

Regulatory Compliance: Both parts must maintain RoHS3 compliance status to satisfy regulatory requirements across target markets.

The substitute part Molex 2143720003 satisfies all substitution criteria through complete parametric alignment with the main part 2070170010 across these critical dimensions.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: Molex 2070170010 remains the baseline specification for new designs and production orders where supply availability permits. This part maintains Active product status with established manufacturing continuity and full RoHS3 compliance certification.

Substitute Part Selection: Molex 2143720003 is qualified as a direct parametric equivalent for applications requiring supply diversification or inventory management. This part demonstrates identical electrical and mechanical specifications, Active product status, and RoHS3 compliance. The substitute part is drawn from the Mini-Fit Sigma 214372 series, representing an alternative design generation within the same connector family.

Compliance Basis: Both parts satisfy RoHS3 regulatory requirements. Selection between primary and substitute parts may be driven by procurement lead times, inventory availability, or supply chain strategy rather than technical performance differentiation.

Frequently Asked Questions (FAQ)

Q: Can Molex 2143720003 be used as a direct replacement for Molex 2070170010 in existing assemblies?

A: Yes. Both parts share identical specifications across all critical parameters including position count (10), pitch (0.165"), row configuration (2 rows), mounting type (Panel Mount, Snap-In), fastening mechanism (Locking Ramp), insulation material (PA66/Nylon 6/6), and operating temperature range (-40°C ~ 105°C). Physical and electrical interchangeability is confirmed.

Q: Are there differences in the connector series designation between these parts?

A: The parts belong to different design generations within the Molex Mini-Fit Sigma family. The main part 2070170010 is from series 207017, while the substitute 2143720003 is from series 214372. Despite series differentiation, parametric equivalence across all functional specifications ensures interchangeability.

Q: Do both parts require the same contact pins and mating receptacle housings?

A: Yes. The identical pitch (0.165"), position count (10), row spacing (0.165"), and connector geometry ensure compatibility with the same contact pin specifications and mating receptacle housings. Contacts are not included with either housing and must be sourced separately.

Q: What is the significance of the sealed feature on both parts?

A: The sealed feature indicates environmental protection against moisture and contaminant ingress. Both parts maintain this sealed design characteristic, ensuring equivalent environmental performance in applications requiring protection from dust, moisture, or other environmental factors.

Q: Are there any packaging or inventory considerations when selecting between these parts?

A: Both parts are supplied in bag packaging. Current inventory levels differ: 2070170010 has 898 pieces in stock, while 2143720003 has 2527 pieces available. Procurement decisions may factor inventory availability alongside technical equivalence.

Q: Do both parts comply with the same regulatory standards?

A: Yes. Both parts maintain ROHS3 compliance status, satisfying regulatory requirements for restricted substance elimination across target markets. Regulatory compliance is equivalent between the primary and substitute parts.
