Engineering Selection Recommendations

High Current Applications (≥5A per contact): For applications requiring the full 7.5A current rating of the DEM09P500M, substitute parts 09651626817 (6.5A) and 09651627817 (6.5A) from HARTING provide the closest electrical performance. Both maintain the -55°C to 125°C operating range and UL94 V-0 rating. These HARTING parts are ROHS3 compliant, offering regulatory advantage over the non-compliant main part.

Moderate Current Applications (3A to 6A per contact): The TE Connectivity 5745434-8 (6A) and Amphenol ICC FCE17E09PB440 (5A) are suitable for moderate-load circuits. The 5745434-8 maintains full temperature range (-55°C to 125°C) and includes gold-plated brass contacts. The FCE17E09PB440 operates to 85°C maximum and includes integrated filtering and board lock features. Both are RoHS compliant.

Lower Current Applications (≤3A per contact): The Amphenol ICC SD series parts (L717SDE09PA4CH3F, L717SDE09PA4CH4F, L717SDE09PA4CH3R, L717SDE09PA4CH4RC309, and L777SDE09PA4CH4F) are rated for 3A per contact and maintain the full -55°C to 125°C operating range with 250V voltage rating. These parts feature board lock and grounding indents. RoHS compliance varies: L717SDE09PA4CH3F, L717SDE09PA4CH4RC309, and L777SDE09PA4CH4F are compliant; L717SDE09PA4CH4F is non-compliant.

Regulatory Compliance: If RoHS compliance is required, select from HARTING 09651626817, HARTING 09651627817, TE Connectivity 5745434-8, Amphenol ICC FCE17E09PB440, or the compliant Amphenol ICC SD series variants. The DEM09P500M itself is RoHS non-compliant.

Temperature Constraints: Applications limited to -40°C to 85°C may use FCE17E09PB440. All other substitutes support the full -55°C to 125°C range of the original part.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with lower current rating than the DEM09P500M? A: Yes, provided your application does not exceed the substitute's current rating. The DEM09P500M is rated 7.5A per contact; substitutes range from 3A to 6.5A. Verify your circuit's actual current draw before selection.

Q: What is the difference between the HARTING and Amphenol ICC substitute parts? A: HARTING parts (09651626817, 09651627817) are rated 6.5A and feature board lock and grounding indents with copper alloy contacts. Amphenol ICC parts vary by series: FCE17 series offers integrated filtering; SD series (L717, L777) provide lower current ratings (3A) with board lock and grounding indents. All maintain UL94 V-0 flammability.

Q: Are all substitute parts pin-compatible with the DEM09P500M? A: Yes. All listed substitutes share the same 9-position D-Sub shell size (1/DE/E), right-angle through-hole mounting, and solder termination. Physical and electrical interfaces are compatible.

Q: Which substitute offers the best RoHS compliance? A: HARTING 09651626817, HARTING 09651627817, TE Connectivity 5745434-8, Amphenol ICC FCE17E09PB440, and Amphenol ICC L717SDE09PA4CH3F, L717SDE09PA4CH4RC309, and L777SDE09PA4CH4F are all RoHS compliant. The DEM09P500M and L717SDE09PA4CH4F are non-compliant.

Q: What is the backset spacing difference between parts? A: DEM09P500M has 0.406" (10.30mm) backset spacing. HARTING and TE Connectivity parts have 0.409" to 0.454" spacing. Amphenol ICC SD series parts have 0.318" (8.08mm) spacing. Verify PCB layout compatibility before substitution.

Q: Can I substitute a part with different shell finish (cadmium vs. tin plating)? A: Yes, provided environmental and corrosion requirements are met. DEM09P500M uses yellow cadmium plating; most substitutes use tin or bare steel. Tin plating offers better corrosion resistance in many environments. Verify finish suitability for your application's operating conditions.

Q: Which substitute has the highest inventory availability? A: TE Connectivity 5745434-8 has 2054 units in stock, the highest among all listed substitutes.
