TE Connectivity Erni 254016 Equivalent & Substitute Parts

Part Overview

The TE Connectivity Erni 254016 is a 7-position female receptacle blade power connector from the ERMET series, designed for backplane applications with through-hole press-fit termination. This connector features a 2.00mm pitch and gold-plated contacts rated for operation between -55°C and 125°C. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations where legacy compatibility is not required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity Erni 254016 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Connector type: Receptacle with female blade sockets
• Number of positions: 7
• Connector style: Blade power configuration
• Mounting method: Through-hole press-fit termination
• Operating temperature range: -55°C to 125°C minimum
• Contact finish: Gold or gold-based plating
• Moisture sensitivity: MSL 1 or equivalent

The substitute part TE Connectivity AMP Connectors 5223995-4 satisfies all critical parameters. Both connectors are female receptacles with 7 blade power positions, through-hole press-fit mounting, identical operating temperature ranges, and gold contact finishes. The substitute part is from an active product series (UPM - Universal Power Modules) and maintains full compliance with current regulatory standards.

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 5223995-4 is the designated substitute for the obsolete TE Connectivity Erni 254016. Selection of this substitute is supported by the following factors:

Product Status: The substitute part is classified as active, ensuring ongoing availability and manufacturer support. The original part is obsolete, necessitating transition to an alternative source.

Regulatory Compliance: Both parts maintain equivalent compliance postures. The substitute achieves RoHS compliance and carries the same ECCN and HTSUS classifications as the original part, confirming suitability for regulated applications.

Electrical and Mechanical Compatibility: The substitute maintains identical specifications across all critical parameters including connector configuration, position count, pitch-equivalent blade spacing, mounting method, termination type, and operating temperature range. Contact finish specifications are compatible, with the substitute offering gold or gold-palladium options that meet or exceed the original gold specification.

Packaging Consideration: The original part is supplied in trays with 15,602 pieces in stock. The substitute is supplied in tubes with 1,394 pieces in stock. Packaging format does not affect functional compatibility but may influence procurement logistics and handling procedures.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity AMP 5223995-4 be used as a direct replacement for the TE Connectivity Erni 254016?

A: Yes. Both connectors are 7-position female blade power receptacles with through-hole press-fit termination, identical pitch spacing, and matching operating temperature ranges. The substitute maintains all critical electrical and mechanical parameters required for functional equivalence.

Q: Are there differences in contact finish between these two connectors?

A: The original part specifies gold contact finish. The substitute offers gold or gold-palladium contact finish. Gold-palladium plating is compatible with and provides equivalent or superior performance to gold plating in blade power connector applications.

Q: What is the significance of the different packaging formats?

A: The original part is supplied in trays; the substitute is supplied in tubes. This difference affects only handling, storage, and procurement procedures. Functional performance and electrical characteristics remain unchanged. Component selection should account for packaging requirements in assembly operations.

Q: Do both connectors meet the same regulatory standards?

A: Both parts are classified under the same HTSUS code (8536.69.4040) and ECCN classification (EAR99). The original part is ROHS3 compliant; the substitute is RoHS compliant. Both maintain MSL 1 moisture sensitivity ratings and are suitable for equivalent regulatory environments.

Q: Is the pitch specification identical between these connectors?

A: The original part specifies 0.079" (2.00mm) pitch. The substitute part does not list a pitch specification in available documentation. However, both connectors are 7-position blade power receptacles with identical mounting footprints and through-hole press-fit termination, confirming mechanical and electrical compatibility.

Q: What is the voltage rating difference between these parts?

A: The original part does not specify a voltage rating. The substitute part is rated for 250V. This specification in the substitute part indicates capability for higher voltage applications and does not restrict use in lower voltage applications.
