DMF-16-R-N Equivalent & Substitute Parts

Part Overview

The DMF-16-R-N is a rectangular connector header manufactured by Adam Tech, designed for through-hole, right-angle mounting applications. This 16-position connector features a 0.165" (4.20mm) pitch and is rated for 6A at 600VAC. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DMF-16-R-N is determined by strict alignment of the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions and rows (16 positions, 2 rows)
• Mating pitch (0.165" / 4.20mm)
• Mounting configuration (Through Hole, Right Angle)
• Shrouding design (Shrouded - 4 Wall)
• Termination method (Solder)
• Material compliance (UL94 V-2, ROHS3 Compliant)

The Molex 0039301161 (Mini-Fit Jr 5569 series) meets these core substitution criteria. Variations in secondary parameters such as contact finish, insulation height, and post length do not preclude functional equivalence when mating interface geometry and electrical ratings are preserved.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0039301161 is a direct functional substitute for the obsolete DMF-16-R-N. Both connectors share identical mating pitch, position count, mounting orientation, and shrouding configuration. Both are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The Molex part offers the advantage of active product status, ensuring continued availability and supply chain reliability. The gold contact finish on the mating surface of the Molex connector provides enhanced corrosion resistance compared to the tin finish of the original part, which may improve long-term reliability in certain environmental conditions.

Minor dimensional variations in post length (0.012" difference) and insulation height (0.016" difference) are within typical PCB design tolerances and do not affect mechanical or electrical compatibility when proper footprint accommodation is maintained.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0039301161 be used as a direct replacement for the DMF-16-R-N?

A: Yes. Both connectors share identical mating pitch (0.165" / 4.20mm), position configuration (16 positions, 2 rows), mounting type (through-hole right-angle), and shrouding design (4-wall shrouded). Electrical and mechanical compatibility is maintained.

Q: What is the significance of the different contact finishes?

A: The DMF-16-R-N uses tin plating on mating contacts, while the Molex 0039301161 uses gold plating. Gold provides superior corrosion resistance and is suitable for applications requiring extended shelf life or exposure to corrosive environments. Tin is adequate for standard industrial applications.

Q: Are there any dimensional concerns when substituting these parts?

A: The post length differs by 0.012" (3.30mm vs. 3.60mm) and insulation height by 0.016" (10.00mm vs. 9.60mm). These variations are within standard PCB design tolerances. Verify that your PCB footprint accommodates the Molex connector dimensions before implementation.

Q: Do both connectors meet current compliance standards?

A: Yes. Both the DMF-16-R-N and Molex 0039301161 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: Why is the DMF-16-R-N listed as obsolete?

A: The DMF-16-R-N has been discontinued by Adam Tech. The Molex 0039301161 remains in active production, making it the recommended choice for new designs and ongoing system support.
