TE Connectivity AMP Connectors 103148-8 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 103148-8 is an 8-position rectangular connector header with through-hole, right-angle mounting and 0.100" (2.54mm) pitch. This connector belongs to the AMPMODU Mod II series and is designed for board-to-board or cable applications with solder termination and push-pull fastening.

The 103148-8 is classified as obsolete. Identifying active equivalent parts is necessary to ensure continued component availability, supply chain reliability, and compliance with current manufacturing standards for new designs or production continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the 103148-8 is determined by strict equivalence across the following critical parameters:

Connector type (Header, Breakaway)
Contact type (Male Pin)
Number of positions (8)
Mating pitch (0.100" / 2.54mm)
Mounting configuration (Through Hole, Right Angle)
Termination method (Solder)
Fastening mechanism (Push-Pull)
Current rating per contact (3A)
Operating temperature range (-65°C ~ 105°C)
Material flammability compliance (UL94 V-0)

The substitute part 5-146304-8 meets all these critical parameters. Variations in secondary attributes such as contact finish thickness, insulation material composition, or product status do not affect functional interchangeability when these core parameters remain equivalent.

Engineering Selection Recommendations

The 5-146304-8 is the direct active equivalent for the obsolete 103148-8. Both parts are manufactured by TE Connectivity within the same AMPMODU Mod II series and maintain identical electrical and mechanical specifications across all critical parameters.

The primary distinction is product status: 103148-8 is obsolete, while 5-146304-8 is active and currently in production. For new designs, production continuity, or component replenishment, the 5-146304-8 should be selected. Both parts carry identical compliance certifications (UL94 V-0, EAR99, HTSUS 8536.69.4040) and moisture sensitivity ratings (MSL 1).

The substitution is direct with no design modifications required. Pin configuration, mating interface, mounting footprint, and electrical performance are fully compatible.

Frequently Asked Questions (FAQ)

Q: Can the 5-146304-8 be used as a direct replacement for the 103148-8 in existing designs?

A: Yes. Both parts are functionally equivalent across all critical parameters: 8-position, 0.100" pitch, through-hole right-angle header with male pins, solder termination, and 3A current rating. No PCB layout or assembly modifications are required.

Q: What is the difference between the contact finish specifications?

A: The 103148-8 specifies Tin-Lead post finish (100.0µin / 2.54µm), while the 5-146304-8 specifies Tin post finish (100.0µin / 2.54µm). Both provide equivalent solder joint reliability and electrical performance. The post finish thickness remains identical at 100.0µin.

Q: Does the glass-filled thermoplastic insulation in the 5-146304-8 affect compatibility?

A: No. The glass-filled thermoplastic composition in the 5-146304-8 maintains the same mechanical and electrical properties as the standard thermoplastic in the 103148-8. Both materials meet UL94 V-0 flammability requirements and operate across the identical temperature range (-65°C ~ 105°C).

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical compliance designations: UL94 V-0 material flammability rating, EAR99 export classification, and HTSUS code 8536.69.4040. Moisture sensitivity level is MSL 1 (Unlimited) for both.

Q: Why is the 103148-8 obsolete if the 5-146304-8 is functionally identical?

A: Product obsolescence reflects manufacturing lifecycle decisions by TE Connectivity. The 5-146304-8 represents the current active production equivalent within the AMPMODU Mod II series. Inventory availability for the 103148-8 is limited (830 pcs), while the 5-146304-8 maintains active stock (833 pcs).

Q: Can these parts be intermixed in the same assembly?

A: Yes. Both parts are mechanically and electrically interchangeable. They can be used together in the same board assembly or cable harness without compatibility issues.
