TE Connectivity 8134-HC-8P3 Pin Receptacle Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 8134-HC-8P3 is a pin receptacle connector from the HOLTITE series, designed for press-fit termination of pins with diameters between 0.025" and 0.035" (0.64mm to 0.89mm). This component features a beryllium copper contact material with tin-lead finish and operates across a temperature range of -55°C to 105°C. The part is classified as obsolete, necessitating identification of active equivalent alternatives to maintain design continuity and ensure ongoing component availability for new production and field service applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 8134-HC-8P3 is determined by strict equivalence across all mechanical and electrical parameters. The substitute part must maintain identical specifications for pin acceptance diameter (0.025" ~ 0.035"), pin hole diameter (0.042"), mounting hole diameter (0.058"), overall length (0.136"), board thickness (0.030"), termination method (press-fit), tail configuration (no tail), contact material (beryllium copper), and operating temperature range (-55°C ~ 105°C). These parameters define the physical and functional compatibility required for direct substitution in existing circuit board designs and connector assemblies.

Parameter Comparison

Engineering Selection Recommendations

The 8134-HC-8P3-LF serves as the direct active equivalent to the obsolete 8134-HC-8P3. Both components are manufactured by TE Connectivity and belong to the HOLTITE series with identical mechanical and electrical specifications. The primary distinction is product status: the original part is obsolete while the substitute is active and currently in production.

A secondary consideration is regulatory compliance. The 8134-HC-8P3-LF is RoHS compliant, whereas the original 8134-HC-8P3 is RoHS non-compliant. This distinction is relevant for applications subject to RoHS directives or customer specifications requiring lead-free components. The contact finish differs between the two parts: the original uses tin-lead while the substitute uses tin. Both finishes maintain the same thickness specification of 80.0µin (2.03µm) and are compatible with the beryllium copper base material and identical operating temperature range.

For new designs and production applications, the 8134-HC-8P3-LF is the appropriate selection due to its active status and RoHS compliance. For legacy system maintenance where the original tin-lead finish is specifically required, the obsolete 8134-HC-8P3 may be sourced from existing inventory, though long-term availability is limited.

Frequently Asked Questions (FAQ)

Q: Are the 8134-HC-8P3 and 8134-HC-8P3-LF mechanically interchangeable?

A: Yes. Both components share identical mechanical specifications including pin hole diameter (0.042"), mounting hole diameter (0.058"), overall length (0.136"), and board thickness (0.030"). They accept the same pin diameter range (0.025" ~ 0.035") and square pin size (0.025"). Direct substitution in existing circuit board designs is supported.

Q: What is the difference between the contact finishes?

A: The original 8134-HC-8P3 features a tin-lead contact finish, while the substitute 8134-HC-8P3-LF uses a tin finish. Both maintain the same finish thickness of 80.0µin (2.03µm). The tin finish in the substitute reflects the RoHS compliance requirement, which restricts lead content in electronic components.

Q: Why is the 8134-HC-8P3 listed as obsolete?

A: The original part has been discontinued by TE Connectivity. The 8134-HC-8P3-LF represents the active production equivalent and is the recommended component for all new applications.

Q: Does the RoHS compliance status affect electrical performance?

A: No. Both components maintain identical electrical specifications including contact material (beryllium copper), operating temperature range (-55°C ~ 105°C), and contact finish thickness (80.0µin). RoHS compliance is a regulatory and material composition designation, not an electrical performance parameter.

Q: Can the 8134-HC-8P3-LF be used in applications originally designed for the 8134-HC-8P3?

A: Yes. The substitute part is fully compatible with existing designs. All mechanical and electrical parameters are identical. The only consideration is the contact finish change from tin-lead to tin, which does not affect functional compatibility in standard applications.

Q: What is the press-fit termination method?

A: Press-fit termination is a solderless connection method where the component is mechanically pressed onto a pin or lead. The 0.042" pin hole diameter accommodates pins within the 0.025" ~ 0.035" diameter range, creating a secure mechanical and electrical connection without solder.

Q: Are both parts available in the same packaging?

A: Packaging information is not specified in the provided data for either component. Contact the manufacturer or authorized distributor for current packaging configurations and availability.
