TE Connectivity AMP Connectors 1-1546462-4 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 1-1546462-4 is a 14-circuit barrier block terminal connector with 0.325" (8.26mm) pitch spacing, designed for through-hole, right-angle mounting applications. This connector features a dual-wall barrier design, screw-based top termination with captive plate, and PC pin bottom termination. The part is classified as Active product status and is ROHS3 compliant with UL94 V-0 flammability rating.

Substitute parts are identified when equivalent barrier block connectors share the same circuit count, pitch spacing, barrier type, and termination methodology while maintaining compatibility within specified electrical and mechanical tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 1-1546462-4 are identified based on strict equivalence of the following critical parameters:

Critical Matching Parameters:

• Terminal Block Type: Barrier Block
• Number of Circuits: 14
• Pitch: 0.325" (8.26mm)
• Number of Rows: 1
• Barrier Type: 2 Wall (Dual)
• Bottom Termination: PC Pin
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

Application-Dependent Parameters: Substitution feasibility depends on circuit design requirements for current rating, voltage rating, and wire gauge compatibility. The main part supports 20A at 150V with 12-22 AWG wire gauge. Substitute parts with lower current or voltage ratings require verification against application specifications.

Termination Consideration: The main part features screws with captive plate top termination. Substitute parts with screw-only termination (without captive plate) represent functional equivalents for applications where captive plate retention is not required.

Engineering Selection Recommendations

Curtis Industries 325111-14-0 Substitution Criteria:

The Curtis Industries 325111-14-0 is a valid substitute for the TE Connectivity 1-1546462-4 when the following conditions are met:

1. Circuit Architecture Compatibility: Both parts feature 14-circuit, single-row barrier block design with 0.325" pitch and dual-wall barrier configuration. PCB footprint and mounting hole spacing are equivalent.

2. Electrical Specification Alignment: The Curtis Industries part supports 15A at 300V. Applications requiring the full 20A capacity of the TE Connectivity part require confirmation that circuit design operates within 15A limits. The higher voltage rating (300V vs. 150V) of the Curtis Industries part provides additional margin for high-voltage applications.

3. Wire Gauge Consideration: The Curtis Industries part accepts 14-22 AWG wire gauge, compared to 12-22 AWG for the TE Connectivity part. Applications using 12 AWG wire require the TE Connectivity part or confirmation that 14 AWG substitution is acceptable.

4. Termination Difference: The Curtis Industries part features screw-only termination without captive plate. Applications requiring captive plate retention for assembly or vibration resistance must use the TE Connectivity part.

5. Compliance Status: Both parts are ROHS3 compliant, UL94 V-0 rated, and carry Active product status. Both meet EAR99 export classification and 8536.90.4000 HTSUS coding.

6. Insulation Material: The TE Connectivity part uses thermoplastic insulation; the Curtis Industries part uses polypropylene (PP). Both materials meet UL94 V-0 flammability requirements.

Frequently Asked Questions (FAQ)

Q: Can the Curtis Industries 325111-14-0 replace the TE Connectivity 1-1546462-4 in all applications?

A: The Curtis Industries part is a functional substitute when application current requirements do not exceed 15A and wire gauge requirements do not include 12 AWG. The absence of captive plate termination may affect assembly procedures in applications requiring positive screw retention during manufacturing.

Q: What is the difference between "Screws with Captive Plate" and "Screws" termination?

A: Screws with captive plate termination includes a metal plate that retains the screw, preventing loss during assembly and providing additional mechanical stability. Screw-only termination requires manual screw handling and does not provide captive retention. Both provide equivalent electrical connection when properly installed.

Q: Are both parts suitable for high-temperature applications?

A: The TE Connectivity part operates from -40°C to 105°C. The Curtis Industries part specification indicates 105°C maximum operating temperature without specified minimum. Both parts are suitable for standard industrial temperature ranges. Applications requiring -40°C minimum temperature operation require the TE Connectivity part.

Q: What is the significance of the pitch specification (0.325")?

A: Pitch defines the center-to-center spacing between adjacent circuits. Both parts feature identical 0.325" (8.26mm) pitch, ensuring equivalent PCB footprint and mounting compatibility. Pitch is a critical parameter for substitution.

Q: Do both parts have the same physical dimensions?

A: Both parts feature identical circuit count (14), pitch (0.325"), row configuration (1), and barrier type (2 Wall Dual). Physical dimensions are equivalent for PCB mounting. The Curtis Industries part lacks captive plate, resulting in minor height variation in the termination area.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For applications requiring 20A capacity, 12 AWG wire support, or captive plate termination, the TE Connectivity 1-1546462-4 is required. For applications within 15A limits using 14-22 AWG wire without captive plate requirement, either part is acceptable. Both parts carry Active status and full compliance certifications.

Q: Are there any moisture sensitivity concerns with either part?

A: Both parts carry MSL 1 (Unlimited) moisture sensitivity level, indicating no moisture sensitivity restrictions for storage, handling, or reflow processes.
