• Mounting & Termination: Surface mount with solder termination
• Electrical Ratings: 1.2A current and 250V voltage capacity
• Mechanical Interface: Shrouded 2-wall construction with push-pull fastening
• Contact Finish & Material: Tin-plated contacts with polyamide nylon insulation
• Compliance: UL94 V-0 flammability and ROHS3 compliance

The Molex 0908140308 meets all substitution criteria across these parameters, enabling direct functional replacement in applications currently specified for the 0934050308.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0908140308 is the primary substitute for the obsolete Molex 0934050308. Both components are ROHS3 compliant and carry identical electrical ratings, mechanical interfaces, and application certifications.

The 0908140308 holds active product status, ensuring ongoing availability and supply chain support. The insulation height differential (0.293" versus 0.252") represents a minor mechanical variation that does not affect functional compatibility in standard board-to-cable/wire configurations.

Selection of the 0908140308 eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with existing designs specified for the 0934050308.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0908140308 directly replace the 0934050308 in existing designs?

A: Yes. Both connectors share identical pitch (0.050"), position count (8), contact type (male blade), electrical ratings (1.2A/250V), and mechanical fastening (push-pull). The 0908140308 is functionally equivalent for board-to-cable/wire applications.

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

A: The 0908140308 has an insulation height of 0.252" compared to 0.293" on the 0934050308. This 0.041" reduction does not impact mating compatibility or electrical performance in standard applications. PCB layout and clearance requirements should be evaluated for specific designs.

Q: Why is the 0934050308 listed as obsolete?

A: The 0934050308 has reached end-of-life status. The 0908140308 represents the current production equivalent within the Molex Picoflex connector family, offering the same functional specifications with active manufacturing support.

Q: Are there compliance differences between these parts?

A: No. Both components are ROHS3 compliant, UL94 V-0 rated, carry MSL 1 (Unlimited) moisture sensitivity, and share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: What contact material is used in each connector?

A: The 0934050308 uses cartridge brass contacts, while the 0908140308 uses brass contacts. Both are tin-plated at 118.1µin (3.00µm) thickness and deliver equivalent electrical performance and corrosion resistance.
