B14B-EH-A Equivalent & Substitute Parts

Part Overview

The B14B-EH-A is a rectangular connector header manufactured by JST Sales America Inc., designed for through-hole mounting applications. This 14-position, single-row connector operates at 3A current rating and 250V voltage rating, with a 0.098" (2.50mm) pitch. The part is actively produced and RoHS3 compliant, making it suitable for board-to-cable/wire interconnection in general industrial applications. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory constraints require component flexibility.

The substitute part 1-440052-4 (TE Connectivity AMP Connectors) meets all critical electrical and mechanical parameters required for direct substitution in applications currently using the B14B-EH-A.

Parameter Comparison

Engineering Selection Recommendations

Both the B14B-EH-A and 1-440052-4 are active production parts with ROHS3 compliance and UL94 V-0 flammability certification. The parts are electrically and mechanically equivalent across all specified parameters. Selection between these parts may be based on:

• Inventory availability and lead time requirements
• Supplier relationship and pricing considerations
• Series preference (EH series for JST; HPI series for TE Connectivity)
• Insulation material specification (Polyamide PA66 for JST; Thermoplastic for TE Connectivity)

Both parts satisfy identical electrical performance requirements and environmental operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the 1-440052-4 be used as a direct replacement for the B14B-EH-A?

A: Yes. Both parts meet identical specifications for connector type, position count, pitch, mounting method, current rating, voltage rating, operating temperature range, and flammability rating. The parts are mechanically and electrically interchangeable.

Q: Are there differences in contact dimensions between these parts?

A: Contact length specifications differ slightly. The B14B-EH-A has a mating contact length of 0.130" (3.30mm) and post length of 0.126" (3.20mm). The 1-440052-4 has a mating contact length of 0.136" (3.45mm) and post length of 0.134" (3.40mm). These variations remain within acceptable tolerances for the 2.50mm pitch connector class and do not affect functional compatibility.

Q: What is the difference in insulation material between these parts?

A: The B14B-EH-A uses Polyamide (PA66) nylon 6/6 insulation, while the 1-440052-4 uses Thermoplastic insulation. Both materials meet UL94 V-0 flammability requirements and operate across the identical temperature range of -25°C to 85°C.

Q: Are both parts RoHS compliant?

A: Yes. Both the B14B-EH-A and 1-440052-4 are ROHS3 compliant with MSL rating of 1 (Unlimited moisture sensitivity level).

Q: What applications are these connectors suitable for?

A: The B14B-EH-A is specified for general industrial applications. The 1-440052-4 is rated for automotive, general purpose, industrial, and medical applications. Both parts support board-to-cable/wire interconnection in through-hole mounting configurations.
