Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0934050316 is determined by strict equivalence across the following critical parameters:

• Connector type (Header) and contact type (Male Blade)
• Position count (16) and mating pitch (0.050"/1.27mm)
• Mounting method (Surface Mount) and termination type (Solder)
• Shrouding configuration (Shrouded - 2 Wall) and fastening mechanism (Push-Pull)
• Electrical ratings: 1.2A current and 250V voltage minimum
• Contact finish (Tin) and insulation material (Polyamide/Nylon, Glass Filled)
• Compliance certifications (UL94 V-0, ROHS3)

The Molex 0908140316 meets all substitution criteria as an active product within the Picoflex series, maintaining full electrical and mechanical compatibility while offering current production availability.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0908140316 is the direct substitute for the obsolete 0934050316. Both connectors maintain identical electrical specifications (1.2A, 250V), mechanical configuration (16-position, 0.050" pitch, surface mount, push-pull), and compliance certifications (UL94 V-0, ROHS3 Compliant). The 0908140316 offers the advantage of active product status with current manufacturing availability, ensuring supply chain continuity for new production and design updates. The minor dimensional difference in insulation height (0.252" versus 0.293") is within acceptable mechanical tolerance for board-level integration and does not affect electrical performance or mating compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 0908140316 directly replace the 0934050316 in existing designs?

A: Yes. The 0908140316 maintains full electrical and mechanical compatibility with identical pitch, position count, contact type, current/voltage ratings, and termination method. The insulation height difference is a minor dimensional variation that does not impact functional performance or PCB layout compatibility.

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

A: No. Both parts carry identical certifications: UL94 V-0 flammability rating, ROHS3 compliance, and MSL 1 (Unlimited) moisture sensitivity level. Both are suitable for automotive, general purpose, industrial, and medical applications.

Q: What is the primary reason for substitution?

A: The 0934050316 is obsolete. The 0908140316 is an active product from Molex's Picoflex series with current manufacturing and inventory availability, providing supply security for ongoing production requirements.

Q: Are the contact materials equivalent?

A: Yes. Both use tin-plated contacts with 118.1µin (3.00µm) finish thickness. The 0934050316 specifies cartridge brass while the 0908140316 specifies brass; both materials provide equivalent electrical and mechanical performance for this connector class.

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

A: The 0908140316 has a 0.041" (1.04mm) lower insulation height. This is a minor dimensional variation that does not affect mating compatibility, electrical performance, or standard PCB assembly processes. Verify clearance in applications with height-constrained layouts.
