Engineering Selection Recommendations

Primary Substitute: TE Connectivity AMP Connectors 5223995-3

The TE Connectivity AMP Connectors 5223995-3 is the recommended substitute for the obsolete TE Connectivity Erni 254927. This selection is based on the following engineering criteria:

1. Functional Equivalence: Both connectors provide 6-position power distribution through identical mounting and termination methods. The female blade socket configuration of the substitute is functionally equivalent to the female socket design of the original part for power connector applications.

2. Product Status: The substitute part maintains active production status, ensuring long-term availability and supply chain continuity. The original part's obsolete status creates procurement risk for ongoing applications.

3. Compliance Alignment: Both parts meet RoHS compliance requirements and maintain MSL 1 (Unlimited) moisture sensitivity ratings, ensuring compatibility with current manufacturing and storage protocols.

4. Temperature Performance: Identical operating temperature range (-55°C to 125°C) ensures thermal performance equivalence across all specified operating conditions.

5. Electrical Specifications: The substitute part's 250V voltage rating exceeds the original specification, providing enhanced electrical performance margin for power distribution applications.

6. Contact Finish: Gold or gold-palladium contact finish on the substitute part provides equivalent corrosion resistance and electrical conductivity to the original gold-plated contacts.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity AMP 5223995-3 directly replace the TE Connectivity Erni 254927 in existing applications?

A: Yes. Both connectors share identical specifications for number of positions (6), mounting type (through-hole), termination method (press-fit), operating temperature range (-55°C to 125°C), and row configuration (1). The female blade socket design of the substitute is functionally equivalent to the female socket design for power distribution applications.

Q: What is the primary reason for substitution?

A: The TE Connectivity Erni 254927 is classified as obsolete, creating supply chain risk. The TE Connectivity AMP 5223995-3 is an active production part that meets all functional and compliance requirements of the original connector.

Q: Are there differences in contact geometry between these connectors?

A: The original part features female sockets, while the substitute features female blade sockets. Both configurations provide equivalent electrical performance for power connector applications and are compatible with standard mating connectors in the respective product families.

Q: Does the substitute part meet the same compliance standards?

A: Both parts are RoHS compliant and maintain MSL 1 (Unlimited) moisture sensitivity ratings. The substitute part's RoHS compliance status is confirmed, ensuring compatibility with current manufacturing and environmental regulations.

Q: What is the packaging difference between these parts?

A: The original part packaging is not specified in available documentation. The substitute part is supplied in tube packaging, which is standard for backplane connector distribution.

Q: Is the voltage rating difference significant?

A: The substitute part is rated for 250V, while the original part's voltage rating is not specified. This represents an enhancement in electrical performance margin and does not create compatibility issues for applications using the original part.

Q: Are both parts suitable for through-hole PCB assembly?

A: Yes. Both connectors are designed for through-hole mounting with press-fit termination, making them suitable for standard PCB assembly processes without modification to existing board designs.
