B8P-VH-B Equivalent & Substitute Parts

Part Overview

The B8P-VH-B is an 8-position vertical header connector manufactured by JST Sales America Inc., designed for through-hole board-to-cable/wire applications. This shrouded rectangular connector features a 0.156" (3.96mm) pitch and is rated for 10A at 250V, making it suitable for general-purpose industrial and power distribution applications. The connector is currently in active production status with ROHS3 compliance and UL94 V-0 flammability rating. Equivalent parts are identified when alternative manufacturers offer connectors with matching electrical and mechanical specifications that allow direct functional substitution in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the B8P-VH-B is determined by strict alignment of the following critical parameters:

• Connector type (Header) and contact type (Male Pin)
• Number of positions (8) and mating pitch (0.156" / 3.96mm)
• Mounting method (Through Hole) and termination type (Solder)
• Shrouding configuration (Shrouded - 1 Wall)
• Electrical ratings: minimum current capacity and voltage rating
• Material compliance: UL94 V-0 flammability and ROHS3 status
• Operating temperature range compatibility

The substitute part 1-1123723-8 from TE Connectivity AMP Connectors meets these core substitution criteria, allowing it to function as a direct equivalent in applications requiring the B8P-VH-B specification.

Parameter Comparison

Engineering Selection Recommendations

Both the B8P-VH-B and 1-1123723-8 are active production connectors with ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for industrial and general-purpose applications.

The B8P-VH-B is the primary specification with a 10A current rating and operating temperature range of -25°C to 85°C. The 1-1123723-8 substitute from TE Connectivity provides equivalent mechanical and electrical functionality with the following considerations:

The TE Connectivity part carries a 7.5A current rating, which is lower than the JST specification. Applications requiring the full 10A capacity must use the B8P-VH-B. The TE part offers an extended operating temperature range to 105°C, providing additional thermal margin in high-temperature environments.

The insulation height differs between the two parts (9.40mm versus 3.00mm), reflecting different mechanical designs. This dimensional variance requires physical verification during board layout and assembly planning to ensure clearance compatibility with surrounding components and enclosure constraints.

Both connectors share identical mating pitch, contact geometry, termination method, and shrouding configuration, ensuring mechanical interchangeability at the connector interface level.

Frequently Asked Questions (FAQ)

Q: Can the 1-1123723-8 be used as a direct replacement for the B8P-VH-B in all applications?

A: The 1-1123723-8 is mechanically and electrically compatible for applications requiring up to 7.5A at 250V. Applications demanding the full 10A rating specified for the B8P-VH-B require the JST part. The significant difference in insulation height (9.40mm versus 3.00mm) must be evaluated for physical fit within the target assembly.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is based on matching connector type, contact type, number of positions, mating pitch (0.156"), mounting method (through-hole), termination type (solder), shrouding configuration, and compliance certifications (UL94 V-0, ROHS3). Electrical ratings and operating temperature ranges must meet or exceed application requirements.

Q: Does the TE Connectivity part meet the same compliance standards?

A: Yes. The 1-1123723-8 is ROHS3 compliant and carries UL94 V-0 flammability certification, matching the B8P-VH-B compliance profile.

Q: What is the significance of the insulation height difference?

A: Insulation height affects the overall connector profile and clearance requirements on the printed circuit board. The B8P-VH-B has an insulation height of 0.370" (9.40mm), while the TE part measures 0.118" (3.00mm). This dimensional difference requires physical verification during PCB layout to ensure compatibility with component placement and enclosure constraints.

Q: Are there packaging differences between these parts?

A: The B8P-VH-B is supplied in standard packaging, while the 1-1123723-8 is available in bulk packaging. Procurement and inventory management processes should account for packaging format differences.

Q: What is the operating temperature range for each connector?

A: The B8P-VH-B operates from -25°C to 85°C. The 1-1123723-8 operates from -25°C to 105°C, providing a 20°C higher upper temperature limit. Applications in elevated-temperature environments may benefit from the TE part's extended range.
