Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity Erni 054528 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Header, Male Pins
• Number of positions: 154 (110 + 44 Ground)
• Pitch: 0.079" (2.00mm)
• Number of rows: 5 + 2
• Mounting type: Through Hole
• Termination method: Press-Fit
• Connector style: A 22
• Contact finish: Gold

Compliance Considerations:

• RoHS compliance status
• Moisture Sensitivity Level (MSL)
• ECCN and HTSUS classifications

The substitute parts identified below satisfy all mandatory matching parameters and maintain regulatory compliance suitable for direct replacement in backplane connector applications.

Engineering Selection Recommendations

Primary Substitute: TE Connectivity AMP 5188399-1

The TE Connectivity AMP Connectors 5188399-1 is the manufacturer-recommended substitute for the obsolete TE Connectivity Erni 054528. This part maintains complete electrical and mechanical equivalence across all critical parameters, including identical pitch, position count, row configuration, and termination method. The 5188399-1 is classified as active product status with RoHS compliance and carries identical ECCN and HTSUS classifications. The operating temperature range of -55°C ~ 125°C matches the original specification, and the MSL rating of 1 (Unlimited) ensures compatibility with standard handling and storage protocols. This substitute is available in tube packaging with 1392 units in stock.

Secondary Substitute: 3M CP2-HA110-GA1-KR

The 3M CP2-HA110-GA1-KR is a similar alternative that satisfies all mandatory matching parameters for connector type, position count, pitch, row configuration, mounting type, termination method, and connector style. This part is active product status with RoHS compliance and identical ECCN and HTSUS classifications. The operating temperature range of -40°C ~ 85°C is narrower than the original specification, limiting applicability to environments within this reduced range. The part includes board guide features and is designated for CompactPCI Hot Swap applications. This substitute is available in bulk packaging with 721 units in stock.

Selection Criteria:

For applications requiring the full operating temperature range of -55°C ~ 125°C, the TE Connectivity AMP 5188399-1 is the appropriate selection. For applications operating within -40°C ~ 85°C, the 3M CP2-HA110-GA1-KR provides an alternative with equivalent mechanical and electrical characteristics. Both substitutes maintain RoHS compliance and regulatory alignment with the original part.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity AMP 5188399-1 directly replace the TE Connectivity Erni 054528 in existing designs?

A: Yes. The 5188399-1 maintains complete equivalence across all critical parameters: 154-position configuration, 2.00mm pitch, 5 + 2 row arrangement, press-fit termination, through-hole mounting, A 22 connector style, and gold contact finish. Both parts operate across -55°C ~ 125°C and carry identical regulatory classifications.

Q: What is the key difference between the TE Connectivity AMP 5188399-1 and the 3M CP2-HA110-GA1-KR?

A: The primary difference is the operating temperature range. The TE Connectivity AMP 5188399-1 operates from -55°C ~ 125°C, matching the original specification. The 3M CP2-HA110-GA1-KR operates from -40°C ~ 85°C, which is narrower. Both parts are mechanically and electrically equivalent in all other respects.

Q: Are there packaging differences between the substitute parts?

A: Yes. The TE Connectivity AMP 5188399-1 is supplied in tube packaging, while the 3M CP2-HA110-GA1-KR is supplied in bulk packaging. Packaging selection depends on inventory management and assembly process requirements.

Q: Do both substitute parts meet RoHS compliance requirements?

A: Yes. Both the TE Connectivity AMP 5188399-1 and the 3M CP2-HA110-GA1-KR are RoHS compliant. The original TE Connectivity Erni 054528 is ROHS3 compliant, and both substitutes maintain RoHS compliance status suitable for regulated applications.

Q: What is the MSL rating for the substitute parts?

A: Both substitute parts carry an MSL rating of 1 (Unlimited), identical to the original part. This rating indicates unlimited shelf life under standard storage conditions without moisture sensitivity concerns.

Q: Are the contact finish specifications identical across all three parts?

A: All three parts feature gold contact finish. The TE Connectivity AMP 5188399-1 and 3M CP2-HA110-GA1-KR specify a contact finish thickness of 30.0µin (0.76µm), while the original part does not specify thickness. The specified thickness on the substitutes ensures consistent contact resistance and durability.

Q: Can the 3M CP2-HA110-GA1-KR be used in applications requiring -55°C operation?

A: No. The 3M CP2-HA110-GA1-KR is rated for -40°C ~ 85°C operation and is not suitable for applications requiring the full -55°C ~ 125°C range of the original part. The TE Connectivity AMP 5188399-1 must be used for such applications.
