TE Connectivity Erni 114153 Equivalent & Substitute Parts

Part Overview

The TE Connectivity Erni 114153 is a 169-position backplane connector header with male pins, featuring a 2.00mm pitch and press-fit termination. This connector is classified as obsolete, which necessitates identification of active equivalent alternatives for new designs and ongoing production requirements. The part operates across an extended temperature range of -55°C to 125°C and incorporates shielding with gold-plated contacts. Locating functionally compatible substitutes ensures design continuity and supply chain reliability for applications requiring this connector specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity Erni 114153 is determined by strict equivalence across the following critical parameters: connector type (Header, Male Pins), position count (169 positions with 125 + 44 ground configuration), pitch specification (2.00mm), row configuration (5 + 2), mounting method (Through Hole), termination technology (Press-Fit), contact finish (Gold), and operating temperature range (-55°C to 125°C). All identified substitute parts maintain these core electrical and mechanical characteristics, enabling direct functional replacement in applications designed for the original connector. The substitute parts are sourced from TE Connectivity AMP Connectors within the Z-PACK series and carry active product status, providing long-term availability and supply security.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity Erni 114153 is obsolete and requires substitution for new production and design implementations. Both identified substitute parts—5646529-1 and 646529-1—are active products from TE Connectivity AMP Connectors and maintain full electrical and mechanical compatibility with the original connector specification.

5646529-1 is the manufacturer-recommended substitute. This part carries RoHS Compliant certification and is suitable for applications requiring modern regulatory compliance. The contact finish is specified as gold with 30.0µin (0.76µm) thickness, providing documented contact durability specifications. This part is the preferred selection for new designs and applications subject to RoHS requirements.

646529-1 is an alternative substitute that maintains identical electrical and mechanical parameters. However, this part is RoHS non-compliant and REACH-affected, making it unsuitable for applications requiring regulatory compliance with current environmental standards. This part may be considered only for legacy system maintenance where RoHS compliance is not a requirement.

Both substitute parts provide current rating (1.5 A) and voltage rating (500Vrms) specifications not documented in the original part, indicating enhanced electrical performance characterization in the active product line.

Frequently Asked Questions (FAQ)

Q: Can the 5646529-1 directly replace the obsolete 114153 in existing designs?

A: Yes. The 5646529-1 maintains identical position count (169), pitch (2.00mm), row configuration (5 + 2), mounting type (Through Hole), termination method (Press-Fit), and operating temperature range (-55°C to 125°C). No design modifications are required for direct substitution.

Q: What is the difference between 5646529-1 and 646529-1?

A: Both parts are mechanically and electrically identical. The primary differences are regulatory compliance status: 5646529-1 is RoHS Compliant, while 646529-1 is RoHS non-compliant and REACH-affected. For new designs and applications requiring environmental compliance, 5646529-1 is the appropriate selection.

Q: Are there packaging differences between the substitute parts?

A: Both substitute parts are supplied in Tube packaging. The original 114153 packaging specification was not provided. Tube packaging is standard for backplane connectors of this size and position count.

Q: Does the contact finish specification affect substitution compatibility?

A: The 5646529-1 specifies gold contact finish with 30.0µin (0.76µm) thickness, matching the original part's gold finish requirement. The 646529-1 contact finish is not specified. Both parts maintain the gold finish characteristic necessary for the application.

Q: What electrical performance parameters should be considered for substitution?

A: The substitute parts provide current rating (1.5 A) and voltage rating (500Vrms) specifications. These ratings define the maximum electrical load capacity. Applications must verify that existing circuit requirements do not exceed these specifications. The original 114153 did not document these ratings.

Q: Is the Z-PACK series compatible with the original ERMET series application?

A: Yes. Series designation indicates product line organization within the manufacturer's portfolio. Substitution compatibility is determined by the electrical and mechanical parameters listed in this document, not by series name. The Z-PACK series parts meet all specified requirements for the ERMET application.
