Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0444720253 is determined by strict equivalence across the following critical parameters:

• Connector type, contact type, and gender (Header, Male Pin)
• Position count and row configuration (2 positions, 2 rows)
• Row spacing measurement (0.165" / 4.20mm)
• Mounting method (Through Hole)
• Termination type (Solder)
• Shrouding design (Shrouded - 4 Wall)
• Fastening mechanism (Locking Ramp)
• Contact geometry and material (Square, Copper Alloy)
• Insulation material specification (Polyamide PA66, Nylon 6/6)
• Physical dimensions (Insulation height 0.504" / 12.80mm, Post length 0.138" / 4.60mm)
• Contact finish specifications (Tin plating, 100.0µin thickness on both mating and post surfaces)
• Compliance certifications (ROHS3, UL94 flammability rating)

The substitute part 0444720250 meets all these criteria and belongs to the same Mini-Fit HCS 44472 series, with the distinction of active product status and different packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0444720250 is the direct functional equivalent to the obsolete 0444720253. Both components share identical electrical and mechanical specifications across all critical parameters including connector geometry, contact configuration, termination method, and material composition.

The primary distinction between these parts is product lifecycle status: the 0444720253 is obsolete while the 0444720250 maintains active production status. This makes the 0444720250 the appropriate selection for new designs, production continuity, and component replenishment.

Both parts maintain ROHS3 compliance and carry MSL rating of 1 (Unlimited), confirming suitability for standard handling and storage conditions. The flammability ratings differ slightly (UL94 V-0 versus UL94 V-2), with the main part offering superior flame resistance. The substitute part carries explicit REACH Unaffected certification, providing additional regulatory documentation for supply chain compliance.

Packaging configuration differs between the two parts: the substitute is supplied in Tray packaging, which may require adjustment to existing procurement and inventory management procedures.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0444720250 directly replace the 0444720253 in existing applications?

A: Yes. The 0444720250 is functionally equivalent across all electrical and mechanical parameters. Both components feature identical connector geometry, contact configuration, row spacing, mounting method, and material specifications. The primary difference is product status: the 0444720253 is obsolete while the 0444720250 is in active production.

Q: What is the significance of the different flammability ratings (UL94 V-0 versus UL94 V-2)?

A: The main part carries UL94 V-0 rating, indicating superior flame resistance compared to the substitute's UL94 V-2 rating. Both ratings satisfy standard flammability requirements for connector applications. Selection between these parts should consider specific application requirements and regulatory standards applicable to the end product.

Q: Does the Tray packaging of the 0444720250 affect compatibility?

A: Packaging format does not affect component compatibility or performance. Tray packaging is a supply and handling consideration only. The electrical and mechanical specifications remain identical regardless of packaging configuration.

Q: Are both parts suitable for automotive and medical applications?

A: Yes. Both the 0444720253 and 0444720250 are specified for automotive, general purpose, industrial, medical, and telecommunications applications. Both maintain ROHS3 compliance and MSL rating of 1 (Unlimited), confirming suitability for these sectors.

Q: What does REACH Unaffected status mean for the 0444720250?

A: REACH Unaffected status indicates that the component is not subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulatory requirements. This certification simplifies compliance documentation for supply chains operating under European chemical regulations.

Q: Are there any dimensional differences between these parts?

A: No. Both components share identical physical dimensions: insulation height of 0.504" (12.80mm), contact post length of 0.138" (4.60mm), and row spacing of 0.165" (4.20mm). These specifications ensure mechanical interchangeability in PCB layouts and mating connector designs.
