Substitute Part Grouping Explanation

Substitution of the Molex 0934050504 is determined by strict equivalence across the following critical parameters:

• Connector type (Header) and contact type (Male Blade)
• Pitch specification (0.050" / 1.27mm)
• Position count (4 positions, single row)
• Mounting method (Surface Mount)
• Shrouding configuration (Shrouded - 2 Wall)
• Fastening mechanism (Push-Pull)
• Electrical ratings (1.2A current, 250V voltage)
• Contact finish (Tin plating)
• Flammability compliance (UL94 V-0)
• RoHS compliance status (ROHS3 Compliant)

The Molex 0908140504 meets all these criteria and is classified as an active product, providing continuity for applications previously using the obsolete 0934050504.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0908140504 is the direct substitute for the obsolete Molex 0934050504. Both components maintain identical electrical specifications, mechanical interfaces, and compliance certifications. The 0908140504 is currently in active production with substantial inventory availability (24,104 pieces), ensuring supply chain continuity.

The primary difference between the two parts is the insulation height: the substitute features a 0.252" (6.40mm) insulation height compared to the original 0.203" (5.16mm). This dimensional variance must be evaluated against PCB layout and mating connector specifications to ensure mechanical compatibility in the target application.

Both parts carry ROHS3 compliance, UL94 V-0 flammability rating, and REACH unaffected status, maintaining regulatory alignment for automotive, industrial, medical, and general purpose applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0908140504 be used as a direct replacement for the 0934050504 in existing designs?

A: The 0908140504 matches all critical electrical and functional parameters. However, the increased insulation height (0.252" versus 0.203") requires verification against PCB layout constraints and mating connector specifications before implementation.

Q: What is the significance of the insulation height difference?

A: Insulation height affects the overall profile of the connector assembly and its interaction with mating components. The 0908140504's greater height may impact board-to-board spacing or clearance requirements in compact designs.

Q: Are both parts compatible with the same mating connectors?

A: Both components feature identical pitch (1.27mm), position count (4), contact type (Male Blade), and shrouding configuration. Mating connector compatibility depends on the specific connector design and its tolerance specifications.

Q: Why is the original part obsolete?

A: The 0934050504 has been discontinued by Molex. The 0908140504 represents the current production equivalent within the Picoflex series.

Q: What are the packaging considerations for the substitute part?

A: The 0908140504 is supplied in Tape & Reel (TR) packaging, consistent with the original part's packaging format.

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

A: Both parts maintain identical compliance status: ROHS3 compliant, REACH unaffected, UL94 V-0 flammability rating, and EAR99 export classification.
