Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF7-9P-3.96DSA(25) is determined by the following critical parameters:

• Pitch - Mating: 0.156" (3.96mm) — must match exactly for mechanical and electrical compatibility
• Number of Positions: 9 — connector must accommodate all 9 signal paths
• Connector Type & Contact Type: Header with Male Pin contacts
• Mounting Type: Through Hole — PCB mounting method must remain consistent
• Shrouding Configuration: Shrouded - 4 Wall — mechanical protection and keying alignment
• Termination Method: Solder — assembly process compatibility
• Insulation Material & Flammability: UL94 V-0 rated materials for safety compliance

The two substitute parts listed below meet these core substitution criteria while offering active product status and enhanced availability.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts satisfy the core mechanical and electrical compatibility requirements for the DF7-9P-3.96DSA(25). Selection between them depends on specific application requirements:

1877285-9 (TE Connectivity AMP Connectors) — This part offers active product status with extended operating temperature range (-25°C ~ 105°C), specified current rating of 7.5A at 250VAC, and ROHS3 compliance. The Economy Power series provides industrial-grade reliability with brass contact material and PBT insulation. This option is suitable for applications requiring higher temperature performance and documented electrical specifications.

B9P-VH-FB-B (JST Sales America Inc.) — This part provides active product status with a higher current rating of 10A at 250V and ROHS3 compliance. The VH series features copper alloy contacts and PBT insulation. Operating temperature range is -25°C ~ 85°C, matching the upper limit of the original part. This option is suitable for applications requiring higher current capacity.

Both parts carry UL94 V-0 flammability ratings, MSL 1 (Unlimited) moisture sensitivity, and identical core connector geometry (9-position, 0.156" pitch, shrouded 4-wall, through-hole solder termination). The choice between them should be based on application-specific requirements for current capacity, temperature range, and contact material compatibility with mating connectors.

Frequently Asked Questions (FAQ)

Q: Can the 1877285-9 or B9P-VH-FB-B be used as direct replacements for the DF7-9P-3.96DSA(25)?

A: Both parts meet the core substitution criteria: identical 9-position, 0.156" (3.96mm) pitch configuration, shrouded 4-wall construction, through-hole solder termination, and UL94 V-0 flammability rating. Physical and electrical compatibility is established through these matching parameters. Fastening mechanism differs (Locking Ramp vs. Latch Holder), but both provide secure mating.

Q: What are the key differences between the two substitute parts?

A: The 1877285-9 offers extended operating temperature range (-25°C ~ 105°C) and 7.5A current rating. The B9P-VH-FB-B provides higher current capacity (10A) with operating temperature range of -25°C ~ 85°C. Contact material differs: 1877285-9 uses brass; B9P-VH-FB-B uses copper alloy. Insulation color also varies (White vs. Natural).

Q: Are both substitute parts RoHS compliant?

A: Yes, both 1877285-9 and B9P-VH-FB-B are ROHS3 compliant. The original DF7-9P-3.96DSA(25) RoHS status is not specified in the provided data.

Q: What is the significance of the fastening type difference (Latch Holder vs. Locking Ramp)?

A: Both fastening mechanisms provide secure mating and retention. Latch Holder and Locking Ramp are different mechanical approaches to the same functional requirement. Selection depends on mating connector design and assembly process compatibility.

Q: Do the substitute parts have the same moisture sensitivity level?

A: Yes, all three parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Which substitute part should be selected for high-temperature applications?

A: The 1877285-9 supports operating temperatures up to 105°C, making it suitable for applications requiring extended temperature performance beyond the original part's -35°C ~ 85°C range.

Q: Which substitute part should be selected for high-current applications?

A: The B9P-VH-FB-B provides 10A current rating, compared to 7.5A for the 1877285-9, making it the appropriate choice for applications requiring higher current capacity.
