MD40-19S HDMI Plug Connector - Equivalent & Substitute Parts

Part Overview

The MD40-19S is a 19-position HDMI plug connector manufactured by Hirose Electric Co Ltd, designed for free hanging (in-line) solder termination applications. This connector is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system support, maintenance, and new design implementations where this connector type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MD40-19S must satisfy the following core electrical and mechanical parameters:

• Connector Type: HDMI
• Number of Contacts: 19 positions
• Gender: Plug configuration
• Mounting Type: Free Hanging (In-Line)
• Termination Method: Solder
• Contact Finish: Gold plating
• Shell Material: Copper Alloy
• Flammability Rating: UL94 V-0

The DCC-HD19T-310 manufactured by Conxall/Switchcraft meets these primary substitution criteria. This part maintains functional equivalence for HDMI signal transmission and mechanical compatibility in free hanging solder applications.

Parameter Comparison

Engineering Selection Recommendations

The DCC-HD19T-310 is the manufacturer-recommended substitute for the obsolete MD40-19S. Both connectors maintain UL94 V-0 flammability compliance and equivalent gold-plated contact construction.

Key considerations for selection:

• The DCC-HD19T-310 is actively manufactured and available in production quantities, addressing the obsolescence of the MD40-19S.
• Operating temperature range differs: the substitute operates within -20°C ~ 80°C versus the original -55°C ~ 85°C. Applications requiring extended low-temperature operation below -20°C or high-temperature operation above 80°C require thermal performance verification.
• Mating cycle rating is reduced in the substitute (350 cycles versus 10000 cycles). Applications with frequent connector mating cycles require cycle count evaluation.
• Shielding configuration differs: the MD40-19S is shielded while the DCC-HD19T-310 is unshielded. Applications requiring EMI/RFI protection must account for this difference.
• The DCC-HD19T-310 includes circular threaded coupling and IP67/IP68 ingress protection, providing enhanced environmental sealing not present in the original design.

Frequently Asked Questions (FAQ)

Q: Can the DCC-HD19T-310 directly replace the MD40-19S in existing designs?

A: The DCC-HD19T-310 maintains mechanical and electrical compatibility for HDMI signal transmission in free hanging solder applications. However, differences in operating temperature range, mating cycle rating, and shielding configuration must be evaluated against specific application requirements before implementation.

Q: What is the significance of the shielding difference between these connectors?

A: The MD40-19S features shielding for EMI/RFI protection, while the DCC-HD19T-310 is unshielded. Applications in electromagnetically noisy environments may require additional shielding measures if substituting with the DCC-HD19T-310.

Q: Why does the DCC-HD19T-310 have a lower mating cycle rating?

A: The DCC-HD19T-310 is rated for 350 mating cycles compared to the MD40-19S rating of 10000 cycles. This difference reflects different design specifications and intended use cases. Applications requiring frequent connector engagement must verify this parameter against operational requirements.

Q: What does the IP67/IP68 rating on the DCC-HD19T-310 provide?

A: The IP67/IP68 ingress protection rating indicates dust-tight and waterproof performance. This feature is not present in the MD40-19S and may provide additional environmental protection in applications exposed to moisture or particulate contamination.

Q: Are both connectors RoHS compliant?

A: The DCC-HD19T-310 is ROHS3 compliant. Compliance information for the MD40-19S is not provided in the available specifications.

Q: What is the packaging difference between these parts?

A: The MD40-19S is supplied in standard packaging, while the DCC-HD19T-310 is supplied in bulk packaging. Verify packaging requirements for procurement and assembly processes.
