DF7-6P-3.96DSA Equivalent & Substitute Parts

Part Overview

The DF7-6P-3.96DSA is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole mounting with 6 positions at 0.156" (3.96mm) pitch. This connector features shrouded 4-wall construction with solder termination and latch holder fastening. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Substitute Part Grouping Explanation

Substitution of the DF7-6P-3.96DSA is determined by strict alignment of the following electrical and mechanical parameters:

Connector type (Header) and contact type (Male Pin)
Mating pitch of 0.156" (3.96mm)
Position count of 6 in single-row configuration
Through-hole mounting with solder termination
Shrouded 4-wall construction
Copper alloy contacts with tin finish
UL94 V-0 flammability rating
Operating temperature compatibility

The substitute part B6P-VH-FB-B from JST Sales America Inc. meets these core substitution criteria. Both connectors share identical mating pitch, position count, row configuration, mounting method, termination type, shrouding style, contact material, contact finish, and flammability rating.

Engineering Selection Recommendations

The B6P-VH-FB-B from JST Sales America Inc. is the designated substitute for the obsolete DF7-6P-3.96DSA. Both connectors share identical core electrical and mechanical specifications for mating pitch, position count, mounting configuration, and termination method.

The JST substitute offers the advantage of active product status with current manufacturing availability. The B6P-VH-FB-B achieves ROHS3 compliance, whereas the original DF7-6P-3.96DSA is RoHS non-compliant. This compliance improvement supports modern procurement and regulatory requirements.

Operating temperature range differs slightly: the DF7-6P-3.96DSA operates from -35°C to 85°C, while the B6P-VH-FB-B operates from -25°C to 85°C. Applications requiring operation below -25°C must account for this specification difference.

Insulation material differs between the two connectors: the original uses polyamide (PA) nylon glass-filled material, while the substitute uses polybutylene terephthalate (PBT) glass-filled material. Both materials achieve UL94 V-0 flammability rating. The different insulation materials may affect mechanical properties and environmental resistance characteristics specific to application requirements.

Frequently Asked Questions (FAQ)

Q: Can the B6P-VH-FB-B directly replace the DF7-6P-3.96DSA in existing designs?

A: The B6P-VH-FB-B meets all core substitution criteria for mating pitch, position count, mounting type, termination method, and shrouding configuration. Physical compatibility is established. Applications operating below -25°C require evaluation of the narrower operating temperature range of the JST substitute.

Q: What are the key differences between these two connectors?

A: The primary differences are product status (obsolete vs. active), RoHS compliance status (non-compliant vs. ROHS3 compliant), operating temperature lower limit (-35°C vs. -25°C), and insulation material composition (polyamide vs. polybutylene terephthalate). All other electrical and mechanical parameters are identical.

Q: Does the change in insulation material affect electrical performance?

A: Both materials achieve UL94 V-0 flammability rating. Insulation material differences may affect mechanical properties, environmental resistance, and long-term performance under specific operating conditions. Application-specific requirements should be evaluated.

Q: Is the B6P-VH-FB-B available in the same packaging as the original?

A: The B6P-VH-FB-B is supplied in bulk packaging, whereas the original DF7-6P-3.96DSA packaging information is not specified in available data. Packaging format should be confirmed with the supplier for procurement purposes.

Q: What is the fastening type difference between these connectors?

A: The DF7-6P-3.96DSA uses a latch holder fastening type, while the B6P-VH-FB-B uses a locking ramp fastening type. Both provide mechanical retention for mated connections. Mating interface compatibility should be confirmed for specific applications.
