MD-80SMW Equivalent & Substitute Parts

Part Overview

The MD-80SMW is an 8-position circular connector receptacle with female sockets designed for solder termination. Manufactured by CUI Devices, this Mini DIN connector features a through-hole, right-angle mounting configuration with push-pull fastening and keyed orientation. The connector is shielded, rated for 1A–2A current and 100VAC/12VDC voltage, with an operating temperature range of -25°C to 85°C.

The MD-80SMW is classified as obsolete. Locating equivalent or substitute parts becomes necessary when inventory is depleted or when design updates require components with extended availability and improved specifications.

Key Parameters

Substitute Part Grouping Explanation

The MD-80SM qualifies as a direct substitute for the MD-80SMW based on alignment across all critical electrical and mechanical parameters. Substitution eligibility is determined by the following criteria:

Matching Parameters:

• Connector type, gender, and socket configuration (Receptacle, Female Sockets)
• Position count (8 positions)
• Shell size and form factor (Mini DIN)
• Mounting method and orientation (Through Hole, Right Angle, Keyed)
• Termination technology (Solder)
• Fastening mechanism (Push-Pull)
• Shell material composition (PBT)
• Contact finish specification (Silver)
• Shielding configuration (Shielded)
• Electrical ratings (1A–2A current, 100VAC/12VDC voltage)
• Contact material (Phosphor Bronze)
• Regulatory compliance (RoHS, EAR99, HTSUS classification)

Differences:

• Operating temperature range: MD-80SM extends to -40°C (versus -25°C minimum on MD-80SMW)
• Product status: MD-80SM is active; MD-80SMW is obsolete
• Packaging: MD-80SM supplied in Tray; MD-80SMW packaging not specified
• Flammability rating: MD-80SM rated UL94 V-0; MD-80SMW rating not provided
• Moisture sensitivity: MD-80SM rated MSL 1 (Unlimited); MD-80SMW not applicable

Parameter Comparison

Engineering Selection Recommendations

The MD-80SM is a qualified substitute for the MD-80SMW. Both components share identical electrical and mechanical specifications across all critical parameters. The MD-80SM offers the following advantages:

• Active product status: Ensures ongoing availability and supply chain continuity, eliminating obsolescence risk associated with the MD-80SMW.
• Extended temperature range: The MD-80SM operates from -40°C to 85°C, providing a 15°C lower minimum operating threshold compared to the MD-80SMW (-25°C to 85°C). This extended range accommodates applications requiring enhanced cold-temperature performance.
• Enhanced compliance: The MD-80SM carries ROHS3 certification and UL94 V-0 flammability rating, meeting current regulatory standards and material safety requirements.
• Standardized packaging: Supplied in Tray format, facilitating inventory management and automated assembly processes.
• Moisture sensitivity specification: Rated MSL 1 (Unlimited), indicating superior moisture tolerance during storage and handling.

Selection of the MD-80SM is appropriate for new designs, redesigns, and replacement applications where the MD-80SMW is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the MD-80SM directly replace the MD-80SMW in existing designs?

A: Yes. Both connectors share identical electrical ratings (1A–2A, 100VAC/12VDC), mechanical form factor (8-position Mini DIN, through-hole right-angle solder receptacle), and functional specifications. The MD-80SM is electrically and mechanically interchangeable with the MD-80SMW.

Q: What is the significance of the extended operating temperature range on the MD-80SM?

A: The MD-80SM operates from -40°C to 85°C, compared to the MD-80SMW range of -25°C to 85°C. This 15°C extension at the lower temperature limit allows the MD-80SM to function in colder environments. If your application operates within the MD-80SMW temperature range (-25°C to 85°C), both parts perform identically in this overlap region.

Q: Why is the MD-80SMW classified as obsolete?

A: Obsolescence typically reflects end-of-life status, indicating that the manufacturer has discontinued production. The MD-80SM, as an active product from the same manufacturer, represents the current equivalent offering.

Q: Are there packaging differences between these connectors?

A: Yes. The MD-80SM is supplied in Tray packaging, while the MD-80SMW packaging specification is not provided. Tray packaging is standard for automated assembly and high-volume production environments.

Q: What does the UL94 V-0 rating on the MD-80SM indicate?

A: UL94 V-0 is a flammability classification indicating that the material (PBT shell) meets stringent flame-retardant requirements. This certification is not specified for the MD-80SMW but is present on the MD-80SM, reflecting current material safety standards.

Q: Are both connectors RoHS compliant?

A: Yes. The MD-80SMW is RoHS Compliant, and the MD-80SM is ROHS3 Compliant. Both meet lead-free and hazardous substance restrictions. ROHS3 represents the current regulatory standard.

Q: What is the MSL rating, and why does it differ between these parts?

A: Moisture Sensitivity Level (MSL) indicates moisture absorption risk during storage. The MD-80SMW lists MSL as Not Applicable, while the MD-80SM is rated MSL 1 (Unlimited), meaning it can be stored indefinitely without moisture-related degradation concerns.
