UT07128PH Equivalent & Substitute Parts

Part Overview

The UT07128PH is an 8-position circular connector receptacle housing manufactured by Souriau-Sunbank by Eaton, part of the Trim Trio® UTO series. This panel-mount receptacle housing is designed for male pins with bayonet lock fastening and IP67 ingress protection. The component is actively produced and maintained in inventory (1148 pcs available), making it suitable for new designs and production applications. Substitute parts are identified when original inventory is unavailable, when supply chain optimization is required, or when equivalent performance specifications allow for alternative sourcing from qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

The RT07128PNH from Amphenol Sine Systems Corp qualifies as a direct substitute based on the following critical parameters that determine functional equivalence:

Matching Parameters:

• 8-position circular connector receptacle housing
• Shell size 12-8 insert configuration
• Panel mount with bulkhead front side nut mounting feature
• Bayonet lock fastening mechanism
• IP67 ingress protection rating
• Operating temperature range -40°C ~ 105°C
• Nickel-plated zinc alloy shell construction
• Shielded configuration
• UL94 V-0 flammability compliance
• ROHS3 compliance
• Contact size 16

Acceptable Variations:

• Contact type: UT07128PH supports both crimp and solder; RT07128PNH supports crimp only. Crimp contact compatibility is maintained.
• Insert material: UT07128PH uses thermoplastic glass-filled material; RT07128PNH uses thermoplastic material. Both materials meet mechanical and environmental requirements.
• Moisture sensitivity level: UT07128PH is not applicable; RT07128PNH is MSL 1 (Unlimited). This represents an improvement in moisture tolerance.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (UT07128PH): Use the UT07128PH when original equipment specifications explicitly require the Trim Trio® UTO series or when solder contact capability is a design requirement. This part maintains active production status and has higher current inventory availability.

Substitute Selection (RT07128PNH): The RT07128PNH from Amphenol Sine Systems Corp is functionally equivalent for applications requiring 8-position circular receptacle housings with bayonet lock fastening and IP67 protection. This substitute is appropriate when:

• Crimp contact termination is acceptable
• Supply chain diversification is beneficial
• The ecomate® RM series meets application requirements
• Both parts maintain identical compliance certifications (ROHS3, REACH Unaffected, EAR99)

Both parts satisfy UL94 V-0 flammability requirements and operate across the identical temperature range. The RT07128PNH offers improved moisture sensitivity classification (MSL 1 Unlimited), which may provide additional reliability in high-humidity environments.

Frequently Asked Questions (FAQ)

Q: Can RT07128PNH replace UT07128PH in existing designs?

A: Yes, provided the design does not require solder contact termination. The RT07128PNH supports crimp contacts only, while the UT07128PH supports both crimp and solder. All other mechanical, electrical, and environmental parameters are equivalent.

Q: Are the shell materials compatible?

A: Both parts use nickel-plated zinc alloy shells. The UT07128PH specifies halogen-free material, while the RT07128PNH specification does not explicitly state halogen content. Verify halogen-free requirements with the manufacturer if this is a design constraint.

Q: Do both parts meet the same ingress protection rating?

A: Yes. Both UT07128PH and RT07128PNH are rated IP67 (dust tight and waterproof to 1 meter depth for 30 minutes).

Q: What is the difference in insert material?

A: The UT07128PH uses thermoplastic with glass filler, while the RT07128PNH uses thermoplastic without specified filler. Both materials are suitable for the operating temperature range (-40°C ~ 105°C) and mechanical requirements of 8-position bayonet-lock housings.

Q: Are compliance certifications identical?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both carry UL94 V-0 flammability ratings.

Q: What does MSL 1 (Unlimited) mean for the RT07128PNH?

A: MSL 1 indicates the component has unlimited shelf life without moisture bake-out requirements. The UT07128PH lists MSL as not applicable, which typically indicates the component does not require moisture sensitivity management.

Q: Can these parts be intermixed in the same assembly?

A: Yes, both parts are mechanically and electrically compatible for panel-mount applications with bayonet lock fastening. Ensure all mated connector plugs are compatible with the 12-8 shell size and 8-position configuration.

Q: What is the contact size specification?

A: Both parts use contact size 16, which determines the wire gauge and current-carrying capacity of the mated pin contacts.
