Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3-644087-2 are identified based on functional and electrical compatibility within the rectangular connector and terminal block categories. The primary substitution criteria are:

Critical Matching Parameters:

• Number of Positions: 5
• Connector Type: Header with Male Pins
• Mounting Type: Through Hole
• Termination: Solder
• Pitch Compatibility: 0.156" (3.96mm) or equivalent metric pitch (0.150" / 3.81mm acceptable for terminal block applications)
• Shrouding: Shrouded design
• Material Flammability: UL94 V-0
• RoHS3 Compliance
• MSL Rating: 1 (Unlimited)

Acceptable Variation Parameters:

• Contact finish materials (Gold, Tin, Brass)
• Insulation materials (Thermoplastic glass-filled, PBT glass-filled)
• Operating temperature ranges (provided minimum and maximum bounds are maintained for intended application)
• Voltage ratings (substitute must meet or exceed application requirements)
• Current ratings (substitute must meet or exceed application requirements)

The JST Sales America Inc. B5P-VH-B and On Shore Technology Inc. OSTVE053050 satisfy these criteria as functional equivalents, though with specific parameter variations documented in the comparison table.

Parameter Comparison

Engineering Selection Recommendations

JST Sales America Inc. B5P-VH-B:

The B5P-VH-B is an active product offering direct pitch and position compatibility with the 3-644087-2. Both components share identical mating pitch (0.156" / 3.96mm), 5-position configuration, through-hole solder termination, and shrouded design. The B5P-VH-B maintains ROHS3 compliance, UL94 V-0 flammability rating, and MSL 1 classification.

Key differences include reduced operating temperature range (-25°C to 85°C versus -55°C to 105°C) and lower voltage rating (250V versus 600VAC). The B5P-VH-B is suitable for applications operating within its specified temperature and voltage parameters. Contact finish differs (Tin versus Gold), and contact material is Brass rather than Copper Alloy. The B5P-VH-B features locking ramp fastening versus friction lock on the original part.

On Shore Technology Inc. OSTVE053050:

The OSTVE053050 is classified as a terminal block header rather than a rectangular connector, with a pitch of 0.150" (3.81mm) versus the 0.156" (3.96mm) of the 3-644087-2. This represents a 0.006" (0.15mm) pitch variation. The OSTVE053050 maintains 5-position, through-hole solder termination, and shrouded design (2-side shrouding versus 1-wall).

The OSTVE053050 provides operating temperature range of -30°C to 105°C, encompassing the upper temperature limit of the original part. Voltage rating is 300V (UL), lower than the 600VAC specification. Current rating is 8A (UL). The OSTVE053050 maintains ROHS3 compliance, UL94 V-0 flammability rating, and MSL 1 classification. Contact material is Brass with Tin finish.

Selection between B5P-VH-B and OSTVE053050 depends on application-specific requirements for operating temperature range, voltage rating, current capacity, and mechanical pitch tolerance. The B5P-VH-B provides closer electrical specifications for high-voltage applications, while the OSTVE053050 extends the upper temperature operating limit.

Frequently Asked Questions (FAQ)

Q: Can the B5P-VH-B directly replace the 3-644087-2 in all applications?

A: The B5P-VH-B is mechanically and electrically compatible for applications operating within its specified limits: -25°C to 85°C operating temperature and 250V maximum voltage. Applications requiring the full -55°C to 105°C temperature range or 600VAC voltage rating of the original part require evaluation of the OSTVE053050 or confirmation that the B5P-VH-B meets reduced specifications.

Q: What is the significance of the pitch difference between the 3-644087-2 (0.156") and OSTVE053050 (0.150")?

A: The 0.006" (0.15mm) pitch difference represents a 3.8% variation. This difference affects mechanical compatibility with mating connectors and PCB footprints designed for 0.156" pitch. The OSTVE053050 is suitable only for applications with PCB layouts and mating connectors designed for 0.150" (3.81mm) pitch spacing.

Q: How do the contact finish differences affect performance?

A: The 3-644087-2 features gold-plated mating contacts (30.0µin thickness), providing superior corrosion resistance and contact reliability in harsh environments. The B5P-VH-B and OSTVE053050 feature tin-plated contacts. Tin plating is suitable for general industrial applications but may exhibit reduced performance in high-humidity, corrosive, or high-cycle mating environments compared to gold plating.

Q: Are all three parts RoHS3 compliant?

A: Yes. The 3-644087-2, B5P-VH-B, and OSTVE053050 are all ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity classification, indicating no special moisture handling requirements during storage or assembly.

Q: What is the difference between shrouded 1-wall and shrouded 2-side designs?

A: The 3-644087-2 and B5P-VH-B feature 1-wall shrouding, providing protection on one side of the connector. The OSTVE053050 features 2-side shrouding, providing protection on two sides. This affects mechanical fit, polarization, and insertion guidance. Connectors with different shrouding configurations are not interchangeable with the same mating connectors.

Q: Which substitute part is recommended for new designs?

A: For new designs, the B5P-VH-B (JST VH series) is recommended when operating conditions fall within -25°C to 85°C and 250V maximum. The OSTVE053050 is recommended for applications requiring extended upper temperature operation to 105°C, provided the 0.150" pitch and 2-side shrouding are compatible with the application's mechanical and electrical design.

Q: What are the fastening type differences between these parts?

A: The 3-644087-2 uses friction lock fastening. The B5P-VH-B uses locking ramp fastening. The OSTVE053050 uses solder termination without mechanical fastening. These differences affect mating connector compatibility and insertion/removal force characteristics.
