TE Connectivity Erni 053008 Equivalent & Substitute Parts

Part Overview

The TE Connectivity Erni 053008 is a 175-position backplane connector header with male pins, featuring 0.079" (2.00mm) pitch and press-fit termination. This connector is designed for through-hole mounting applications requiring high-density interconnection across 5 + 2 rows with integrated ground positions (125 signal + 50 ground).

The 053008 is classified as obsolete. Locating equivalent substitute parts is necessary to support ongoing maintenance, repair, and production requirements for systems utilizing this connector configuration.

Substitute Part Grouping Explanation

Substitution of the TE Connectivity Erni 053008 is determined by strict equivalence across the following critical parameters:

Position and Pitch Configuration: The substitute part must maintain 175 total positions (125 signal + 50 ground) with 0.079" (2.00mm) pitch spacing across 5 + 2 row arrangement. This ensures mechanical and electrical compatibility with existing PCB layouts and mating connectors.

Connector Type and Termination: Both the main part and substitute must be header connectors with male pins using press-fit termination for through-hole mounting. This preserves assembly compatibility and electrical performance.

Environmental and Compliance Requirements: Operating temperature range of -55°C ~ 125°C, ROHS3 compliance, and MSL 1 rating must be maintained to ensure functional equivalence across thermal and regulatory specifications.

Contact Material: Gold contact finish is required to maintain electrical performance and corrosion resistance characteristics.

The TE Connectivity AMP Connectors 5100669-1 satisfies all substitution criteria across these parameters.

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 5100669-1 is the manufacturer-recommended substitute for the obsolete 053008. This part maintains full electrical and mechanical equivalence across all critical parameters.

Product Status Advantage: The 5100669-1 carries active product status with 2300 units in stock, ensuring availability for immediate procurement and future supply chain continuity. The 053008, classified as obsolete with limited remaining inventory (821 units), presents long-term sourcing risk.

Compliance and Certification: Both parts maintain ROHS3 compliance and MSL 1 rating. The 5100669-1 provides additional electrical specifications including 1.5 A current rating and 500Vrms voltage rating, which are not specified for the 053008 but represent standard performance for this connector class.

Series Designation: The 5100669-1 belongs to the Z-PACK series within TE Connectivity AMP Connectors product line, representing the current generation equivalent to the legacy ERMET series 053008.

Frequently Asked Questions (FAQ)

Q: Can the 5100669-1 be used as a direct replacement for the 053008 in existing designs?

A: Yes. The 5100669-1 maintains identical position count (175), pitch (2.00mm), row configuration (5 + 2), mounting type (through-hole), and termination method (press-fit). PCB layouts and mating connector interfaces designed for the 053008 are compatible with the 5100669-1.

Q: What is the difference in packaging between these parts?

A: The 053008 packaging specification is not provided in available documentation. The 5100669-1 is supplied in tube packaging. Confirm packaging requirements with your procurement specification before ordering.

Q: Are there electrical performance differences between the 053008 and 5100669-1?

A: Both parts operate across -55°C ~ 125°C and feature gold contact finish. The 5100669-1 specifies 1.5 A current rating and 500Vrms voltage rating. The 053008 does not provide these electrical specifications. These ratings represent standard performance for 2.00mm pitch backplane connectors in this position class.

Q: Why is the 053008 classified as obsolete?

A: The 053008 belongs to the legacy ERMET series. TE Connectivity has transitioned this product line to the current Z-PACK series, of which the 5100669-1 is the active equivalent. Obsolete classification reflects end-of-life status for the legacy series.

Q: Are both parts RoHS compliant?

A: Yes. Both the 053008 and 5100669-1 are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level) rating, suitable for standard storage and handling conditions.

Q: What is the base product number for the 5100669-1?

A: The base product number is 5100669. The suffix "-1" designates the specific configuration variant within this product family.
