04P-FJ

Overview

The JST Sales America Inc. 04P-FJ is a male wire-to-board connector housing from the FJ series, featuring four positions with a 2.5 mm pitch. Designed for cable installation, this straight-mount unit utilizes a polyamide (PA) insulator and brass contacts plated with tin. It supports AWG #28 to #22 wire gauges and operates within a temperature range of -25°C to 85°C, rated for 300V and 3A per contact.

Feature Summary

• Provides secure mechanical retention via an integrated locking tab mechanism.
• Constructed from flame-retardant polyamide material for thermal stability.
• Facilitates reliable electrical connections through tin-plated brass terminals.

Applications

• Consumer electronic device interconnections
• Internal wiring harnesses in small appliances
• Low-voltage signal transmission circuits

Procurement Notes

Verify that the specific ordering suffix matches the required terminal type and insulation color. Confirm compatibility with mating receptacles from the same FJ series family. Ensure the selected variant meets the necessary environmental certifications for your target market before finalizing the purchase order.

Selection Notes

Select this component when a compact, low-profile solution is required for tight spaces. The 2.5 mm pitch allows for higher density compared to standard 2.54 mm connectors. Ensure the design accommodates the specific crimping requirements for the designated wire gauge range.

Part Context

This housing belongs to the FJ series, which is characterized by its slim profile and robust locking features. It serves as the male counterpart to female receptacles, enabling modular assembly in various electronic systems where space constraints are critical.

Replacement Considerations

Direct substitutes include other 4-position, 2.5 mm pitch male housings from compatible families. Verify pinout orientation and locking mechanism geometry before replacing with generic equivalents.

FAQ

Does the 04P-FJ housing include the metal terminals?

No, the housing is sold separately and requires the insertion of appropriate crimp terminals.

What is the maximum current rating for each position?

Each contact position is rated for a maximum current of 3 Amperes.
