DEMD9PJK87 D-Sub Connector Equivalent & Substitute Parts

Part Overview

The DEMD9PJK87 is a 9-position D-Sub plug connector manufactured by ITT Cannon, LLC, featuring right-angle solder termination and male pins. This connector is designed for panel mount and through-hole applications with a 2-row configuration in shell size 1 (DE, E). The part is currently active in production with 680 units in stock.

Substitute parts are necessary when the original manufacturer part becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design requirements allow for functionally equivalent alternatives that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DEMD9PJK87 is determined by the following mandatory parameters:

• 9-position configuration with 2-row layout in shell size 1 (DE, E)
• D-Sub plug connector with male pins
• Right-angle mounting orientation
• Solder termination method
• Steel shell with tin-nickel or nickel plating
• Gold contact finish
• UL94 V-0 flammability rating
• Operating temperature range of -55°C minimum

All four substitute parts meet these core requirements. Variations exist in secondary parameters including current rating, voltage rating, contact material composition, dielectric material type, and packaging format. These variations do not affect mechanical or electrical interchangeability for standard D-Sub applications.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are active products with current manufacturing status. Selection among substitutes should be based on the following criteria:

D09P33E4PA00LF is suitable for applications requiring standard solder termination with tin-nickel plated shell finish. This part maintains the closest electrical specifications to the original DEMD9PJK87 and is available in tray packaging. RoHS compliance status differs from the original part.

D09P33E6RX09LF and D09P33E6RX12LF are functionally equivalent alternatives designed for solder paste reflow processes. These parts feature nickel-plated shells and are available in tray and tape & reel packaging respectively. The tape & reel format (D09P33E6RX12LF) is optimized for automated assembly environments. Both parts are RoHS compliant.

L17HTNEP4F1C offers the highest voltage rating (600V) and extended operating temperature range (-55°C ~ 150°C). This part features a stamped contact form and is suitable for applications requiring enhanced thermal performance. RoHS compliance is confirmed.

All substitute parts maintain mechanical interchangeability through identical shell size, pin count, and right-angle mounting configuration. Packaging format selection should align with manufacturing process requirements.

Frequently Asked Questions (FAQ)

Q: Are all substitute parts mechanically compatible with the DEMD9PJK87?

A: Yes. All substitute parts share identical shell size 1 (DE, E), 9-position configuration, 2-row layout, and right-angle mounting orientation. Mechanical interchangeability is confirmed across all listed alternatives.

Q: What is the difference between solder and solder paste termination?

A: Solder termination (DEMD9PJK87, D09P33E4PA00LF, L17HTNEP4F1C) is applied manually or through wave soldering processes. Solder paste termination (D09P33E6RX09LF, D09P33E6RX12LF) is designed for reflow soldering in automated assembly lines. Both methods achieve equivalent electrical connections.

Q: Which substitute part should I select for automated assembly?

A: D09P33E6RX12LF is packaged in tape & reel format optimized for pick-and-place equipment. D09P33E6RX09LF is available in tray packaging suitable for semi-automated processes. Both feature solder paste termination.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance status reflects manufacturing process and material composition but does not alter electrical or mechanical performance. All parts meet UL94 V-0 flammability requirements.

Q: What is the current rating difference between the DEMD9PJK87 and substitute parts?

A: The DEMD9PJK87 is rated at 7.5A, while most substitutes are rated at 5A per contact. For applications requiring the higher current rating, verify that the 5A specification meets your circuit requirements.

Q: Which substitute part has the highest operating temperature rating?

A: L17HTNEP4F1C supports -55°C ~ 150°C, compared to the DEMD9PJK87 specification of -55°C ~ 125°C. This part is suitable for applications requiring extended thermal performance.

Q: Can I use D09P33E6RX09LF or D09P33E6RX12LF with traditional wave soldering?

A: These parts are designed for solder paste reflow processes. While mechanical compatibility exists, use of solder paste termination parts with wave soldering may not achieve optimal connection quality. Consult process specifications for your manufacturing method.
