D-436-38CS454 Equivalent & Substitute Parts

Part Overview

The D-436-38CS454 is an active-status terminal butt splice connector manufactured by TE Connectivity Aerospace, Defense and Marine. This component is a fully insulated heat shrink crimp splice terminal designed for inline, individual opening connections. The part accommodates 12-16 AWG wire gauges and features a blue body with yellow stripe identification. As an active product with full RoHS3 compliance and unlimited moisture sensitivity rating, this terminal is suitable for aerospace, defense, and marine applications requiring reliable wire splicing.

Equivalent and substitute parts are identified to provide procurement flexibility, support supply chain continuity, and offer alternative sourcing options when the primary part number becomes unavailable or when design requirements permit functional alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitute part identification for the D-436-38CS454 is based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Terminal type classification (Butt Splice, Inline, Individual Openings)
• Crimp termination method
• Fully insulated heat shrink insulation construction
• Two wire entry configuration
• RoHS3 compliance status
• Moisture sensitivity level (MSL 1)
• REACH unaffected status

Wire Gauge Compatibility Logic: The D-436-38CS454 operates within a fixed 12-16 AWG range. Substitute parts must accommodate this wire gauge range either through exact specification or through step-up/step-down capability that includes the 12-16 AWG band within its operational envelope.

The identified substitute part 0191640077 (Molex Perma-Seal series) meets all core substitution criteria and provides wire gauge accommodation through step-up/step-down functionality spanning 10-12 to 14-16 AWG, which fully encompasses the primary part's 12-16 AWG specification.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The D-436-38CS454 remains the specified component for applications requiring exact TE Connectivity Aerospace, Defense and Marine sourcing, fixed 12-16 AWG wire gauge specification, and blue body with yellow stripe color coding. This part maintains active product status with full regulatory compliance.

Substitute Part Selection: The Molex 0191640077 (Perma-Seal series) is suitable as a substitute when:

• TE Connectivity supply is unavailable
• Design specifications permit Molex component integration
• Wire gauge flexibility within the 10-12 to 14-16 AWG range is acceptable
• Step-up/step-down terminal functionality is compatible with application requirements
• Yellow body with blue stripe color identification is acceptable

Both parts maintain identical compliance certifications (RoHS3, REACH unaffected), identical moisture sensitivity ratings (MSL 1), and active product status. Both are supplied in bulk packaging and support crimp termination with fully insulated heat shrink construction.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0191640077 directly replace the TE Connectivity D-436-38CS454?

A: The Molex 0191640077 is functionally compatible as a substitute. Both parts share identical terminal type, termination method, insulation construction, wire entry count, and regulatory compliance. The Molex part accommodates the D-436-38CS454 wire gauge range (12-16 AWG) within its broader 10-12 to 14-16 AWG specification through step-up/step-down capability. Color identification differs (yellow/blue stripe versus blue/yellow stripe).

Q: What is the significance of the step-up/step-down feature on the Molex part?

A: Step-up/step-down functionality allows the Molex 0191640077 to accommodate wire gauge transitions within its specified range. This enables splicing of 10-12 AWG wire to 14-16 AWG wire, or any combination within the 10-12 to 14-16 AWG envelope. The D-436-38CS454 operates within a fixed 12-16 AWG range without this transition capability.

Q: Are there packaging differences between these parts?

A: Both parts are supplied in bulk packaging. The D-436-38CS454 has 1075 pieces in current inventory, while the Molex 0191640077 has 2687 pieces in current inventory. Packaging format is identical for both components.

Q: Do both parts meet aerospace and defense compliance requirements?

A: Both parts are RoHS3 compliant and REACH unaffected. Both maintain MSL 1 (unlimited moisture sensitivity) rating. The D-436-38CS454 is manufactured by TE Connectivity Aerospace, Defense and Marine, a supplier specializing in aerospace and defense applications. The Molex 0191640077 meets equivalent regulatory compliance standards.

Q: What is the difference in color coding between these parts?

A: The D-436-38CS454 features a blue body with yellow stripe. The Molex 0191640077 features a yellow body with blue stripe. Color coding serves identification purposes and may be significant in applications requiring specific color-coded wire splice identification schemes.

Q: Can these parts be used interchangeably in the same assembly?

A: Interchangeability depends on application-specific requirements regarding color identification, wire gauge range flexibility, and manufacturer sourcing specifications. Both parts provide equivalent electrical and mechanical function for butt splice crimp termination with fully insulated heat shrink construction.
