ACT96WE35PN Equivalent & Substitute Parts

Part Overview

The ACT96WE35PN is a 55-position circular connector plug with male pins manufactured by TE Connectivity Deutsch Connectors. This connector is designed for aerospace and military applications, featuring crimp termination, gold-plated mating contacts, and shielded construction compliant with MIL-DTL-38999 Series III specifications. The part is discontinued at DiGi Electronics, necessitating identification of equivalent substitute components that maintain electrical and mechanical compatibility for ongoing system support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACT96WE35PN is determined by strict adherence to the following critical parameters:

Mandatory Compatibility Parameters:

• Connector type must be plug with male pins
• Position count must be 55
• Shell size (insert) must be 17-35 with MIL size E
• Termination method must be crimp
• Fastening type must be threaded
• Mounting configuration must be free hanging (in-line)
• Shielding must be present
• Contact finish must be gold with 50.0µin (1.27µm) thickness
• Contact material must be copper alloy
• Ingress protection must be environment resistant
• Series compliance must be MIL-DTL-38999 Series III

Application Scope: Substitute parts are identified from manufacturers producing MIL-DTL-38999 Series III circular connectors with identical electrical and mechanical specifications. All identified substitutes maintain the same position count, shell geometry, termination method, and environmental protection rating.

Parameter Comparison

Engineering Selection Recommendations

D38999/26KE35PN (Conesys) is the primary substitute for ACT96WE35PN. This connector maintains full mechanical and electrical compatibility with identical shell size (17-35, MIL E), 55-position configuration, crimp termination, threaded fastening, and free hanging mounting. The D38999/26KE35PN operates across an extended temperature range (-65°C ~ 200°C) compared to the original part (-65°C ~ 175°C) and holds ROHS3 compliance status, providing enhanced regulatory alignment for new procurement. Current inventory availability is 992 pieces.

D38999/26WE35PNLC (Amphenol Aerospace Operations) serves as a secondary substitute. This connector housing component is designed for male pins and maintains the same 55-position, 17-35 shell size, and MIL-DTL-38999 Series III compliance. The part features self-locking coupling nut functionality and operates within the original temperature specification (-65°C ~ 175°C). Inventory availability is 978 pieces. Note that this component is a plug housing and does not include contacts.

D38999/26FE35PN (Glenair) is listed as a substitute based on the original part documentation. However, detailed electrical and mechanical specifications are not provided in the available data. This part maintains active product status with 791 pieces in inventory.

Selection between active substitutes should prioritize D38999/26KE35PN for applications requiring full specification documentation and ROHS3 compliance, or D38999/26WE35PNLC for applications requiring self-locking coupling nut features.

Frequently Asked Questions (FAQ)

Q: Can D38999/26KE35PN directly replace ACT96WE35PN in existing assemblies?

A: Yes. Both connectors share identical mechanical specifications: 55 positions, shell size 17-35 (MIL E), crimp termination, threaded fastening, and free hanging mounting configuration. Both are MIL-DTL-38999 Series III compliant with shielded construction and environment-resistant ingress protection.

Q: What is the difference between D38999/26WE35PNLC and the other substitutes?

A: D38999/26WE35PNLC is a plug housing component designed for male pins, whereas ACT96WE35PN and D38999/26KE35PN are complete plug assemblies. The housing component does not include contacts and is intended for integration with separate contact assemblies. This part features self-locking coupling nut functionality.

Q: Does D38999/26KE35PN meet RoHS requirements?

A: Yes. D38999/26KE35PN holds ROHS3 compliance status. The original ACT96WE35PN is RoHS non-compliant. Organizations with RoHS compliance mandates should select D38999/26KE35PN.

Q: Are there temperature rating differences between substitutes?

A: Yes. D38999/26KE35PN operates across -65°C ~ 200°C, providing a 25°C extended upper temperature limit compared to ACT96WE35PN and D38999/26WE35PNLC, both rated -65°C ~ 175°C. Applications requiring operation above 175°C should specify D38999/26KE35PN.

Q: What is the contact finish specification for all substitutes?

A: ACT96WE35PN specifies gold contact finish with 50.0µin (1.27µm) thickness. D38999/26KE35PN maintains identical contact finish specifications. D38999/26WE35PNLC is a housing component without integrated contacts. D38999/26FE35PN contact finish specifications are not provided in available documentation.

Q: Which substitute has the highest current rating?

A: ACT96WE35PN specifies 5A current rating. Current ratings for D38999/26KE35PN and D38999/26WE35PNLC are not provided in available documentation. D38999/26FE35PN current rating is not specified.

Q: Are all substitutes available in current inventory?

A: Yes. D38999/26KE35PN (992 pieces), D38999/26WE35PNLC (978 pieces), and D38999/26FE35PN (791 pieces) are all listed as active products with new original stock available.

Q: What is the significance of the "Tri-Start™ TV" designation on D38999/26WE35PNLC?

A: Tri-Start™ TV is a series designation indicating specific design features of the Amphenol connector. This designation is provided in the product documentation but does not affect mechanical or electrical compatibility with the original ACT96WE35PN specification.
