Key Parameters

Substitute Part Grouping Explanation

Substitution of the H4CME8DM is based on the following critical parameters:

Matching Parameters:

• Manufacturer: Amphenol Industrial Operations
• Series: Helios H4
• Connector Type: Male Coupler
• Wire Gauge Rating: 8 AWG
• Category: Photovoltaic (Solar Panel) Connectors
• RoHS Compliance: RoHS Compliant

Differentiating Parameter:

• Coded, Keyed designation: H4CME8DM is Minus; substitute H4SMC8DM is Plus

The H4SMC8DM serves as the manufacturer-recommended substitute. Both connectors maintain identical electrical and mechanical specifications within the Helios H4 series, with the primary distinction being the keying configuration (Minus versus Plus). This keying difference ensures proper polarity management in photovoltaic systems.

Parameter Comparison

Engineering Selection Recommendations

The H4SMC8DM is the active equivalent for the obsolete H4CME8DM. Both components are manufactured by Amphenol Industrial Operations within the Helios H4 series and maintain identical electrical specifications for 8 AWG photovoltaic applications. The H4SMC8DM carries active product status, ensuring ongoing availability and supply chain continuity.

Selection of the H4SMC8DM is appropriate for new designs and field replacements where the Plus keying configuration aligns with system polarity requirements. Both components maintain RoHS compliance and EAR99 export classification, supporting regulatory and compliance requirements for photovoltaic installations.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between H4CME8DM and H4SMC8DM?

A: The primary difference is the keying configuration. The H4CME8DM features Minus keying, while the H4SMC8DM features Plus keying. Both connectors are mechanically and electrically identical within the Helios H4 series and support 8 AWG wire gauge applications.

Q: Can H4CME8DM and H4SMC8DM be used interchangeably?

A: These connectors are not interchangeable due to their different keying designations. The Minus and Plus configurations ensure proper polarity management in photovoltaic systems. Selection must align with the specific polarity requirements of the application.

Q: Why is the H4CME8DM classified as obsolete?
