Key Parameters

Substitute Part Grouping Explanation

Substitution of the 12D-04BMMA-SL8001 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Plug with male pins (mating interface requirement)
• Number of Positions: 4 (pin count compatibility)
• Shell Size - Insert: M12-4 (mechanical fit and keying)
• Termination Type: Solder Cup (assembly method compatibility)
• Fastening Type: Threaded (installation method)
• Orientation: D (keying orientation)
• Shell Material: Zinc Alloy with Nickel finish (environmental durability)
• Contact Finish: Gold (electrical performance and corrosion resistance)
• Ingress Protection: IP68 (sealing specification)
• Operating Temperature Range: -40°C ~ 105°C (thermal compatibility)

The identified substitute M12D-04BMMA-SL8001 maintains equivalence across all mandatory parameters while offering active product status and enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The M12D-04BMMA-SL8001 substitute part is suitable for applications currently using the obsolete 12D-04BMMA-SL8001 based on the following engineering criteria:

Product Status Consideration: The substitute part maintains active product status with Amphenol LTW, ensuring continued availability and manufacturing support. The main part is classified as obsolete, creating supply chain risk for new production and field replacements.

Compliance Enhancement: The substitute part carries ROHS3 Compliant certification compared to the main part's RoHS Compliant status, indicating alignment with current regulatory requirements. Both parts maintain Moisture Sensitivity Level 1 (Unlimited) and EAR99 ECCN classification.

Electrical and Mechanical Equivalence: All critical parameters determining connector compatibility are maintained across both parts. The M12-4 shell size, 4-position configuration, threaded fastening, D-orientation keying, and IP68 sealing specification ensure mechanical and functional interchangeability in mating applications.

Parameter Specification Differences: The main part specifies 4A current rating; the substitute part specifies 250V voltage rating and cable opening dimensions (0.157" ~ 0.315"). These differences reflect manufacturer documentation practices and do not indicate incompatibility. Both parts utilize identical shell materials, contact finishes, and operating temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can the M12D-04BMMA-SL8001 directly replace the 12D-04BMMA-SL8001 in existing assemblies?

A: The M12D-04BMMA-SL8001 is a receptacle connector (female housing), while the 12D-04BMMA-SL8001 is a plug connector (male housing). These components form a mating pair and are not direct one-to-one replacements. The substitute part is identified as the complementary mating connector for applications requiring both plug and receptacle components from the same product family.

Q: What are the key compatibility parameters for M12-4 circular connectors?

A: Compatibility is determined by: shell size designation (M12-4), number of positions (4), connector type (plug or receptacle), termination method (solder cup), fastening type (threaded), orientation keying (D), shell material and finish (zinc alloy with nickel), contact finish (gold), and ingress protection rating (IP68). Deviation in any of these parameters indicates incompatibility.

Q: Why does the substitute part specify voltage rating while the main part specifies current rating?

A: Manufacturer documentation practices vary. Both parts utilize identical contact materials (copper alloy with gold finish) and shell configurations. The presence of one electrical specification does not indicate absence of the other capability. Both parts are suitable for the same application environments based on their equivalent mechanical and material specifications.

Q: Is the cable opening specification of the substitute part a limiting factor?

A: The cable opening specification (0.157" ~ 0.315" or 4.00mm ~ 8.00mm) for the M12D-04BMMA-SL8001 receptacle defines the acceptable cable diameter range for backshell assembly. This specification is standard for M12-4 receptacle connectors and does not affect compatibility with the plug connector in mating applications.

Q: What is the significance of the product status change from Obsolete to Active?

A: Active product status indicates current manufacturing, quality assurance, and supply chain support from Amphenol LTW. The obsolete status of the main part creates supply risk for new production runs and field service replacements. Selection of the active substitute part ensures long-term component availability and manufacturer support.

Q: Are both parts RoHS compliant for current regulatory requirements?

A: Both parts meet RoHS compliance standards. The substitute part carries ROHS3 Compliant certification, representing the current regulatory standard. The main part carries RoHS Compliant certification. Both designations indicate compliance with hazardous substance restrictions applicable to their respective manufacturing periods.
