PT06E-12-3S Equivalent & Substitute Parts

Part Overview

The PT06E-12-3S is a 3-position circular connector plug with female sockets manufactured by Amphenol Industrial Operations under the MIL-DTL-26482 Series I standard. This connector is an active product designed for aerospace, industrial, instrumentation, mass transit, and military applications. Finding equivalent and substitute parts is necessary to address supply chain variability, compliance requirements, and specific application constraints such as shell finish specifications and backshell features.

Key Parameters

Substitute Part Grouping Explanation

Substitution relationships for PT06E-12-3S connectors are determined by equivalence across core electrical and mechanical parameters. The following parameters establish compatibility for direct substitution:

• Connector Type and Position Configuration: Plug with female sockets in 3-position configuration
• Shell Size and Series Designation: 12-3 insert size within MIL-DTL-26482 Series I, PT
• Termination Method: Solder cup for identical assembly and soldering processes
• Fastening Mechanism: Bayonet lock coupling identical to the main part
• Contact System: Gold-plated copper alloy contacts with specified mating finish
• Environmental Sealing: Environment sealed ingress protection classification
• Temperature Rating: -55°C to 125°C operating range
• Material Classification: Aluminum shell with neoprene insert

The PT06E-12-3S(470) substitute part maintains equivalence across all these core parameters while differing in shell finish specification and backshell features, which are application-dependent selections rather than functional incompatibilities.

Parameter Comparison

Engineering Selection Recommendations

Both PT06E-12-3S(SR) and PT06E-12-3S(470) are active products meeting MIL-DTL-26482 Series I specifications and operate within identical electrical and mechanical parameters. Selection between these parts should be based on specific compliance and application requirements.

The PT06E-12-3S(SR) with olive drab chromate over cadmium finish is suitable for applications where traditional military connector specifications and appearance are primary considerations. However, this part is RoHS non-compliant and REACH-affected.

The PT06E-12-3S(470) with black zinc cobalt finish is the appropriate selection for applications requiring RoHS3 compliance and REACH unaffected status. This variant includes integrated backshell, cable clamp, and coupling nut features, providing enhanced mechanical integration. The shell finish change from chromate to zinc cobalt offers alternative corrosion protection characteristics for specific environmental conditions.

Frequently Asked Questions (FAQ)

Q: What parameters determine whether a PT06E-12-3S substitute is electrically compatible? A: Electrical compatibility is determined by connector type (plug with female sockets), number of positions (3), contact material (copper alloy), contact finish (gold-plated), and the MIL-DTL-26482 Series I designation. Both PT06E-12-3S(SR) and PT06E-12-3S(470) maintain these specifications.

Q: How do shell finish differences affect part substitution? A: Shell finish (olive drab chromate versus black zinc cobalt) is a material selection parameter that affects corrosion resistance and environmental performance but does not change the electrical or mechanical interface. Selection depends on environmental exposure and application-specific corrosion protection requirements.

Q: Are the backshell features different between the two parts? A: Yes. The PT06E-12-3S(SR) includes strain relief, while the PT06E-12-3S(470) includes backshell, cable clamp, and coupling nut features. These are mechanical integration elements that may influence cable retention and assembly procedures but do not affect the core connector interface.

Q: What is the significance of RoHS and REACH compliance differences? A: The PT06E-12-3S(SR) is RoHS non-compliant and REACH-affected, while PT06E-12-3S(470) is ROHS3 compliant and REACH unaffected. Applications subject to RoHS and REACH regulations must use the PT06E-12-3S(470) variant.

Q: Can these parts be used interchangeably in the same assembly? A: Both parts share identical connector interfaces, termination method (solder cup), and electrical specifications. Mechanical compatibility depends on whether backshell feature differences and shell finish specifications align with assembly requirements and application constraints.
