TE Connectivity Erni 043190 Equivalent & Substitute Parts

Part Overview

The TE Connectivity Erni 043190 is a 110 Position Header connector with male pins, featuring 0.079" (2.00mm) pitch and through-hole press-fit termination. This connector is part of the ERMET series and is classified as obsolete. The product operates across a temperature range of -55°C to 125°C and includes a board guide feature. Due to its obsolete status, identification of active equivalent parts is necessary to support ongoing procurement and system maintenance requirements.

Substitute Part Grouping Explanation

Substitution of the TE Connectivity Erni 043190 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

Connector type classification (Header, Male Pins)
Position count (110 positions)
Pitch specification (0.079" / 2.00mm)
Row configuration (5 rows)
Mounting methodology (Through Hole)
Termination technology (Press-Fit)
Contact finish material (Gold)
Operating temperature range (-55°C ~ 125°C)
Physical feature set (Board Guide)

The substitute part TE Connectivity AMP Connectors 5100143-1 satisfies all critical parameters. Both connectors maintain identical mechanical and electrical interface specifications, enabling direct functional substitution in applications requiring 110-position, 2.00mm pitch header connectors with press-fit termination.

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 5100143-1 is the designated substitute for the obsolete TE Connectivity Erni 043190. Selection of the 5100143-1 is supported by the following factors:

Product Status: The 043190 is classified as obsolete, while the 5100143-1 maintains active product status with current manufacturing availability (3040 units in stock versus 710 units for the obsolete part).

Regulatory Compliance: Both connectors maintain ROHS3 compliance and identical moisture sensitivity ratings (MSL 1, Unlimited). The 5100143-1 carries EAR99 ECCN classification, matching the original part.

Electrical and Mechanical Compatibility: All critical interface parameters are identical, including connector type, position count, pitch, row configuration, mounting methodology, termination technology, and operating temperature range. The 5100143-1 provides additional electrical specifications (1.5 A current rating, 500Vrms voltage rating) not documented for the original part.

Series Transition: The substitute represents a transition from the ERMET series to the Z-PACK series within the TE Connectivity product portfolio, both manufactured by TE Connectivity divisions.

Frequently Asked Questions (FAQ)

Q: Can the 5100143-1 be used as a direct replacement for the 043190 in existing designs?

A: Yes. The 5100143-1 satisfies all critical mechanical and electrical interface parameters of the 043190. Both connectors feature identical pitch (2.00mm), position count (110), row configuration (5), mounting type (through hole), termination method (press-fit), and operating temperature range (-55°C to 125°C).

Q: What is the primary reason for substitution?

A: The 043190 is classified as obsolete. The 5100143-1 is an active product with current manufacturing support and documented availability.

Q: Are there packaging differences between these connectors?

A: The 043190 packaging is not specified in the available documentation. The 5100143-1 is supplied in tube packaging. Packaging format does not affect connector functionality or interface compatibility.

Q: Do both connectors meet the same regulatory standards?

A: Yes. Both the 043190 and 5100143-1 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings. Both carry EAR99 ECCN classification.

Q: What electrical specifications should be considered for the 5100143-1?

A: The 5100143-1 is rated for 1.5 A current and 500Vrms voltage. These specifications were not documented for the original 043190 part.

Q: Are there any connector style differences?

A: No. Both connectors use the identical A 22 connector style classification.

Q: What is the contact finish specification for both parts?

A: Both connectors feature gold contact finish. The 5100143-1 specifies a contact finish thickness of 30.0µin (0.76µm).
