B2P-VH-B Equivalent & Substitute Parts

Part Overview

The B2P-VH-B is a rectangular connector header manufactured by JST Sales America Inc., designed for through-hole mounting applications. This 2-position vertical header operates at 10A current rating and 250V voltage rating, with an operating temperature range of -25°C to 85°C. The connector features a 0.156" (3.96mm) pitch, shrouded single-wall design, and solder termination with locking ramp fastening. The product maintains Active status and ROHS3 compliance. Equivalent parts are identified to support procurement flexibility, inventory management, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the B2P-VH-B is determined by strict alignment of the following critical parameters:

Connector pitch (0.156" / 3.96mm), number of positions (2), row configuration (1 row), connector type (header), contact type (male pin), mounting method (through hole), shrouding style (shrouded - 1 wall), termination method (solder), and fastening mechanism (locking ramp) must remain identical. Electrical parameters including current rating, voltage rating, contact material (brass), and contact finish (tin) establish the baseline performance envelope. Environmental compliance certifications (ROHS3, UL94 V-0) and insulation material composition (PBT, glass filled) are non-negotiable for direct substitution.

The substitute part 1-1123723-2 (TE Connectivity AMP Connectors) meets all critical mechanical and electrical compatibility criteria for direct substitution in the B2P-VH-B application.

Parameter Comparison

Engineering Selection Recommendations

The 1-1123723-2 (TE Connectivity AMP Connectors) is a direct mechanical and electrical substitute for the B2P-VH-B. Both connectors maintain identical pitch, position count, row configuration, mounting method, shrouding, termination, and fastening specifications. Both products are ROHS3 compliant and carry UL94 V-0 flammability certification.

The substitute part exhibits a reduced current rating of 7.5A compared to the B2P-VH-B's 10A specification. Applications operating at or below 7.5A current levels are fully compatible with the substitute. The 1-1123723-2 provides an extended operating temperature range (-25°C to 105°C) compared to the B2P-VH-B (-25°C to 85°C), offering broader thermal performance capability. The insulation height differs between the two parts (0.370" versus 0.118"), which may affect board layout and clearance considerations in specific applications.

Both parts maintain identical contact material (brass), contact finish (tin), and insulation material (PBT, glass filled) specifications. Both are rated for 250V operation and carry unlimited moisture sensitivity level (MSL 1) classification.

Frequently Asked Questions (FAQ)

Q: Can the 1-1123723-2 be used as a direct replacement for the B2P-VH-B in all applications?

A: The 1-1123723-2 is mechanically and electrically compatible for applications operating at 7.5A or below. If your application requires the full 10A current rating of the B2P-VH-B, the substitute is not suitable. Verify your circuit's actual current draw before substitution.

Q: What is the significance of the insulation height difference between these connectors?

A: The B2P-VH-B has an insulation height of 0.370" (9.40mm), while the 1-1123723-2 measures 0.118" (3.00mm). This difference affects the physical profile of the connector on the PCB. Verify that your board layout and component clearances accommodate the lower profile of the substitute part.

Q: Are both connectors RoHS compliant?

A: Yes. Both the B2P-VH-B and 1-1123723-2 are ROHS3 compliant and carry UL94 V-0 flammability certification, meeting equivalent environmental and safety standards.

Q: Does the extended operating temperature range of the 1-1123723-2 affect substitution decisions?

A: The 1-1123723-2 operates from -25°C to 105°C, exceeding the B2P-VH-B's -25°C to 85°C range. This extended capability does not restrict substitution; it provides additional thermal margin for applications within the B2P-VH-B's original temperature specification.

Q: What packaging format is available for the 1-1123723-2?

A: The 1-1123723-2 is supplied in bulk packaging, compared to the B2P-VH-B's unspecified packaging format. Confirm packaging requirements for your procurement and assembly processes.

Q: Are the contact dimensions identical between these two connectors?

A: Contact length specifications are identical: mating contact length is 0.303" (7.70mm) and post contact length is 0.146" (3.70mm) for both parts. Overall contact length differs slightly (0.575" versus 0.567"), representing a negligible 0.008" variation that does not affect functional compatibility.
