UT06FC1412SH Equivalent & Substitute Parts

Part Overview

The UT06FC1412SH is a 12-position circular connector plug housing manufactured by Souriau-Sunbank by Eaton, part of the Trim Trio® UTO series. This free-hanging, in-line connector features a bayonet lock fastening mechanism, shielded construction, and is designed for female socket termination with crimp contacts. The connector meets IP67/IP68/IP69K ingress protection ratings and operates across a temperature range of -40°C to 105°C. As an active product with ROHS3 compliance and REACH unaffected status, the UT06FC1412SH remains in current production. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements necessitate alternative specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the UT06FC1412SH is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 12
• Shell Size - Insert: 14-12
• Connector Type: Plug for Female Sockets
• Contact Type: Crimp
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Bayonet Lock
• Orientation: Normal (N)

The MS3126F-14-12S from Amphenol Industrial Operations satisfies these core substitution criteria. Both connectors share identical positional configuration, shell sizing, crimp termination methodology, and bayonet lock engagement. However, material composition, environmental ratings, temperature operating ranges, and compliance certifications differ between the two parts and must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

UT06FC1412SH Selection Criteria: The UT06FC1412SH is the primary choice for applications requiring ROHS3 compliance and REACH unaffected status. This connector is suitable for commercial and industrial applications where halogen-free construction and UL94 V-0 flammability rating are mandatory. The shielded design provides electromagnetic interference mitigation. The nickel-plated zinc alloy shell offers corrosion resistance in standard industrial environments. Active product status ensures continued availability and supply chain stability.

MS3126F-14-12S Selection Criteria: The MS3126F-14-12S is applicable for military, aerospace, and legacy system applications where MIL-DTL-26482 Series I compliance is specified. This connector accommodates extended temperature operation from -55°C to 125°C, exceeding the UT06FC1412SH range. The aluminum construction with olive drab chromate over cadmium finish is standard for military applications. However, this part is RoHS non-compliant and REACH affected, restricting use in commercial and regulated markets. The unshielded configuration differs from the UT06FC1412SH and may not provide equivalent electromagnetic shielding performance.

Substitution Feasibility: Direct substitution between these parts is limited to applications where compliance requirements, temperature ranges, and shielding specifications are not critical differentiators. Both connectors maintain identical mechanical interface geometry and crimp contact compatibility at the 12-position, 14-12 shell size level.

Frequently Asked Questions (FAQ)

Q: Can the MS3126F-14-12S directly replace the UT06FC1412SH in all applications?

A: No. While both connectors share identical positional configuration, shell sizing, and bayonet lock fastening, they differ in shielding (shielded vs. unshielded), compliance certifications (ROHS3 vs. RoHS non-compliant), and operating temperature ranges (-40°C to 105°C vs. -55°C to 125°C). Substitution is application-specific and requires verification of compliance, environmental, and electromagnetic requirements.

Q: What are the key mechanical compatibility factors between these connectors?

A: Both connectors are mechanically compatible at the mating interface level. They share 12-position configuration, 14-12 shell size, bayonet lock engagement, and free-hanging in-line mounting. Crimp contact termination is identical. Mechanical interchangeability is confirmed for these parameters.

Q: Are there compliance or regulatory restrictions on using the MS3126F-14-12S as a substitute?

A: Yes. The MS3126F-14-12S is RoHS non-compliant and REACH affected, making it unsuitable for applications subject to European Union regulations, consumer electronics markets, or commercial procurement standards requiring ROHS3 compliance. The UT06FC1412SH is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: How do the environmental ratings differ between these connectors?

A: The UT06FC1412SH provides IP67/IP68/IP69K ingress protection (dust tight, water resistant, waterproof). The MS3126F-14-12S is rated as environment resistant without specific IP classification. For applications requiring defined ingress protection levels, the UT06FC1412SH specification is more precise.

Q: What is the significance of shielding differences?

A: The UT06FC1412SH is shielded; the MS3126F-14-12S is unshielded. Shielding provides electromagnetic interference (EMI) mitigation. Applications in environments with high electromagnetic noise or requiring EMI suppression should use the shielded UT06FC1412SH. Unshielded connectors are suitable for low-noise environments or where EMI is not a design constraint.

Q: Are the contact materials compatible between these connectors?

A: Both connectors use crimp contact termination. The UT06FC1412SH specifies contact size 16. The MS3126F-14-12S uses copper alloy contacts with gold mating finish. Contact material compatibility depends on the specific contact pins used; however, both support standard crimp termination methods for 12-position, 14-12 shell size connectors.

Q: What is the operating temperature consideration for substitution?

A: The UT06FC1412SH operates from -40°C to 105°C. The MS3126F-14-12S operates from -55°C to 125°C. If the application requires operation below -40°C or above 105°C, the MS3126F-14-12S provides extended range capability. Conversely, if the application operates within -40°C to 105°C, both connectors are suitable from a temperature perspective.

Q: Is inventory availability a factor in selecting between these parts?

A: Both connectors are active products with current inventory. The UT06FC1412SH has 1011 pieces in stock; the MS3126F-14-12S has 1131 pieces in stock. Inventory levels may fluctuate; current availability should be verified at the time of procurement.
