Substitute Part Grouping Explanation

Substitution of the DF3-15S-2DSA(50) is based on strict equivalence of the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with 15 female socket positions
• Pitch Specification: 0.079" (2.00mm) mating pitch
• Electrical Ratings: 3A current capacity and 30VAC voltage rating
• Mechanical Interface: Through-hole solder termination with friction lock fastening
• Contact Material & Finish: Phosphor bronze contacts with gold mating finish and tin post finish
• Environmental Specifications: Operating temperature range -30°C ~ 85°C, UL94 V-0 flammability rating

The DF3-15S-2DSA(55) meets all these critical parameters while offering active product status and improved compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The DF3-15S-2DSA(55) is the direct equivalent substitute for the obsolete DF3-15S-2DSA(50). Both connectors are functionally and mechanically identical across all critical electrical and mechanical parameters. The primary advantages of selecting the DF3-15S-2DSA(55) are:

• Active Product Status: The substitute maintains current manufacturing support from Hirose Electric Co Ltd, ensuring long-term availability and supply chain continuity.
• RoHS Compliance: The DF3-15S-2DSA(55) is RoHS compliant, whereas the original part is non-compliant. This compliance status is significant for applications subject to environmental regulations.
• Standardized Packaging: The substitute is supplied in tube packaging, providing consistent handling and storage conditions.

No electrical, mechanical, or thermal performance differences exist between these parts. Direct substitution is appropriate for all applications currently using the DF3-15S-2DSA(50).

Frequently Asked Questions (FAQ)

Q: Are the DF3-15S-2DSA(50) and DF3-15S-2DSA(55) pin-compatible?

A: Yes. Both connectors have identical 15-position configurations with 0.079" (2.00mm) pitch mating, through-hole solder termination, and friction lock fastening. They are mechanically and electrically interchangeable.

Q: What is the difference between the two part numbers?

A: The primary differences are product status and compliance. The DF3-15S-2DSA(50) is obsolete and RoHS non-compliant, while the DF3-15S-2DSA(55) is an active product with RoHS compliance. All functional and electrical specifications are identical.

Q: Can I use the DF3-15S-2DSA(55) as a direct replacement in existing designs?

A: Yes. The substitute part meets all electrical, mechanical, and thermal requirements of the original part. No design modifications are required.

Q: Does the packaging difference affect compatibility?

A: No. The DF3-15S-2DSA(55) is supplied in tube packaging, which is a standard handling and storage format. This does not affect the connector's performance or compatibility with existing PCB designs or mating components.

Q: Are there any compliance considerations when switching to the substitute?

A: The DF3-15S-2DSA(55) offers improved compliance status with RoHS certification. If your application or market requires RoHS compliance, the substitute part provides this advantage over the original obsolete part.
