DEMV9SNF225 D-Sub Receptacle Connector: Equivalent & Substitute Parts

Part Overview

The DEMV9SNF225 is a 9-position D-Sub receptacle connector manufactured by ITT Cannon, LLC, featuring female sockets for signal applications. This connector is designed for panel mount installation with solder termination and operates across an industrial temperature range of -55°C to 125°C. The part maintains active product status with RoHS compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when design requirements necessitate alternative mounting configurations, shell material specifications, or packaging formats while maintaining electrical and mechanical compatibility within the D-Sub connector category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DEMV9SNF225 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: D-Sub
• Connector Type: Receptacle, Female Sockets
• Number of Positions: 9
• Number of Rows: 2
• Shell Size, Connector Layout: 1 (DE, E)
• Termination: Solder
• Current Rating: 7.5A
• Operating Temperature Range: -55°C ~ 125°C
• Contact Material: Copper Alloy
• Contact Finish: Gold
• Dielectric Material: Polycyclohexylenedimethylene Terephthalate (PCT)
• RoHS Status: RoHS Compliant
• Material Flammability Rating: UL94 V-0

Allowable Variation Parameters:

• Mounting Type: Panel Mount variants (cable side vs. board side flange orientation)
• Shell Material: Stainless Steel or Steel with Tin-Nickel plating
• Flange Feature: Cable Side (4-40) or Board Side (4-40)
• Packaging: Bulk or standard packaging formats

The DEMV9SNA197 qualifies as a direct substitute based on matching all mandatory parameters while differing only in shell material finish and flange orientation, both allowable variations for D-Sub receptacle applications.

Parameter Comparison

Engineering Selection Recommendations

Both the DEMV9SNF225 and DEMV9SNA197 maintain active product status with full RoHS compliance and UL94 V-0 flammability certification. Selection between these parts is determined by mechanical mounting requirements rather than electrical performance.

DEMV9SNF225 Selection Criteria:

• Applications requiring cable-side flange orientation
• Designs utilizing stainless steel shell material for corrosion resistance
• Standard panel mount configurations with cable-side mounting holes

DEMV9SNA197 Selection Criteria:

• Applications requiring board-side flange orientation
• Through-hole panel mount installations
• Designs where tin-nickel plated steel shell material is acceptable
• Bulk packaging requirements

Both connectors deliver equivalent electrical performance with 7.5A current rating, gold-plated copper alloy contacts, and PCT dielectric material across the full -55°C to 125°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can DEMV9SNA197 replace DEMV9SNF225 in existing designs?

A: Substitution is possible only if the design accommodates board-side flange orientation instead of cable-side orientation. The flange position determines mounting hole placement on the panel or PCB. Verify mechanical mounting hole alignment before substitution.

Q: What is the difference between cable-side and board-side flange features?

A: Cable-side flange (DEMV9SNF225) positions mounting holes toward the cable entry direction. Board-side flange (DEMV9SNA197) positions mounting holes toward the PCB or panel rear. This affects panel cutout dimensions and mounting hardware placement.

Q: Are the shell materials electrically equivalent?

A: Yes. Stainless steel (DEMV9SNF225) and tin-nickel plated steel (DEMV9SNA197) both provide equivalent electrical shielding and grounding performance. Material selection is based on environmental corrosion resistance requirements rather than electrical function.

Q: Do both parts support the same wire gauge range?

A: The DEMV9SNF225 specifies 20-28 AWG wire gauge. The DEMV9SNA197 does not specify wire gauge in the provided data. Confirm wire gauge compatibility with the substitute part before final selection.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates unlimited shelf life without moisture bake-out requirements. Both parts can be stored indefinitely without special humidity control or pre-soldering bake procedures.

Q: Are both parts suitable for industrial temperature applications?

A: Yes. Both connectors operate across -55°C to 125°C, meeting industrial temperature requirements. Operating temperature range is identical between the two parts.
