TE Connectivity Erni 044148 Equivalent & Substitute Parts

Part Overview

The TE Connectivity Erni 044148 is a 110-position header connector with male pins, featuring 0.079" (2.00mm) pitch and through-hole press-fit termination. This connector is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning. The part belongs to the ERMET series backplane connector category and maintains ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1).

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity Erni 044148 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector pitch: 0.079" (2.00mm)
• Mounting type: Through hole
• Termination method: Press-fit
• Connector style: A 22
• Connector type: Header with male pins
• Category: Backplane connectors

Position Configuration: The 044148 specifies 110 positions across 5 rows. Substitute parts must accommodate the 110-position functional requirement, though alternative row configurations and additional ground positions are permissible when the total position count meets or exceeds the original specification.

Environmental & Compliance Considerations: Substitute parts must maintain MSL 1 rating and support through-hole PCB assembly processes. RoHS compliance status and REACH applicability are documented for procurement and regulatory assessment purposes.

Engineering Selection Recommendations

TE Connectivity AMP 188834-1 Substitution Assessment:

The TE Connectivity AMP Connectors 188834-1 provides functional equivalence to the obsolete 044148 based on matching connector pitch (2.00mm), mounting type (through hole), termination method (press-fit), connector style (A 22), and connector type (header, male pins). The 188834-1 accommodates 154 total positions, including the required 110 signal positions plus 44 dedicated ground positions, satisfying the position requirement of the original part.

Product Status Advantage: The 188834-1 maintains active product status with documented availability of 500,400 pieces in inventory, providing supply continuity for the obsolete 044148.

Compliance Considerations: The 188834-1 is RoHS non-compliant and REACH-affected, contrasting with the ROHS3-compliant, REACH-unaffected status of the 044148. Organizations subject to RoHS3 or REACH regulatory requirements must evaluate compliance implications prior to substitution.

Performance Specifications: The 188834-1 provides documented electrical ratings (500Vrms, 1.5 A) and operating temperature range (-55°C ~ 125°C) not specified for the 044148. Gold contact finish (30.0µin / 0.76µm) is specified for the substitute part. These specifications support applications requiring defined electrical performance parameters.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity AMP 188834-1 directly replace the 044148 in existing designs?

A: The 188834-1 provides mechanical and electrical compatibility based on matching pitch (2.00mm), mounting type (through hole), termination (press-fit), and connector style (A 22). The 188834-1 accommodates 110 signal positions within its 154-position configuration. PCB layout verification is required to confirm that the additional 44 ground positions and modified row configuration (5 + 2 rows versus 5 rows) do not conflict with existing board designs.

Q: What is the significance of the additional ground positions in the 188834-1?

A: The 188834-1 includes 44 dedicated ground positions in addition to the 110 signal positions, totaling 154 positions. This configuration provides enhanced grounding capability compared to the 044148. Board layout must accommodate the additional ground row structure (5 + 2 rows) to utilize this feature.

Q: Are there compliance differences between these parts?

A: Yes. The 044148 is ROHS3 compliant and REACH unaffected. The 188834-1 is RoHS non-compliant and REACH affected. Organizations operating under RoHS3 or REACH regulatory frameworks must assess whether substitution aligns with applicable compliance requirements.

Q: What packaging format is the 188834-1 supplied in?

A: The 188834-1 is supplied in tube packaging, as specified in the product data. The 044148 packaging format is not specified in available documentation.

Q: Are the electrical ratings of the 188834-1 suitable for the original 044148 application?

A: The 188834-1 specifies 500Vrms voltage rating and 1.5 A current rating. The 044148 does not provide documented electrical ratings. Application requirements must be evaluated against the 188834-1 specifications to confirm suitability.

Q: What is the operating temperature range for these connectors?

A: The 188834-1 operates across -55°C to 125°C. The 044148 does not specify an operating temperature range in available documentation. Application temperature requirements must be assessed against the 188834-1 specification.
