Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity Erni 254893 is determined by the following critical parameters that must align between the original and substitute component:

Primary Substitution Criteria:

• Connector Type: Receptacle with female sockets (maintains mating compatibility)
• Number of Positions: 48 positions (ensures pin count equivalence)
• Contact Finish: Gold plating (preserves electrical performance and corrosion resistance)
• Category: Backplane Connectors (confirms application suitability)
• Mounting Technology: PCB mounting capability (ensures installation compatibility)

The substitute part TE Connectivity AMP Connectors 5650459-5 satisfies all primary substitution criteria, providing a direct functional equivalent with active product status and current manufacturing support.

Engineering Selection Recommendations

Primary Substitute: TE Connectivity AMP Connectors 5650459-5

The 5650459-5 is the manufacturer-recommended substitute for the obsolete 254893. This selection is based on:

1. Functional Equivalence: Identical 48-position DIN receptacle configuration with gold contact finish ensures direct compatibility with mating connectors designed for the original part.

2. Active Product Status: The substitute maintains active manufacturing status with current inventory availability (1169 pieces in stock), ensuring long-term supply chain reliability and technical support.

3. Compliance Certifications: The substitute carries RoHS compliance and UL94 V-0 flammability rating, meeting modern regulatory requirements for electronic component procurement.

4. Series Designation: Classification within the Eurocard series confirms standardized DIN connector architecture and interchangeability within backplane connector applications.

5. Packaging and Availability: Bulk packaging with substantial inventory levels supports both prototype and production-volume requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5650459-5 directly replace the 254893 in existing assemblies?

A: Yes. Both connectors share identical 48-position DIN receptacle configuration with gold-plated contacts. The 5650459-5 is the manufacturer-designated substitute and maintains mechanical and electrical compatibility with mating connectors designed for the original 254893.

Q: What is the significance of "32 Positions Loaded" on the 5650459-5?

A: The 5650459-5 has a total capacity of 48 positions but ships with 32 positions populated with contacts. This configuration accommodates applications requiring fewer active signal paths while maintaining the full 48-position connector footprint for future expansion or customization.

Q: Are there differences in mounting between the original and substitute?

A: Both connectors are PCB-mounted. The 5650459-5 specifies through-hole solder termination, which is the standard mounting method for DIN receptacle connectors in backplane applications.

Q: Does the substitute meet current regulatory standards?

A: Yes. The 5650459-5 carries RoHS compliance certification and UL94 V-0 flammability rating, meeting current electronic component procurement standards. The original 254893, being obsolete, lacks current certification documentation.

Q: What is the operating temperature range for the substitute?

A: The 5650459-5 operates across -55°C to 125°C, covering standard industrial and commercial temperature ranges for backplane connector applications.

Q: Is the substitute available in the same packaging as the original?

A: The 5650459-5 is supplied in bulk packaging. Specific packaging configurations should be confirmed with the distributor based on procurement requirements.
