Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF11-26DP-2DSA(73) is determined by strict equivalence across the following critical parameters:

• Connector Type & Series: Both parts must be Hirose DF11 series rectangular connectors classified as headers
• Position Count & Row Configuration: 26 positions arranged in 2 rows
• Mating Pitch: 0.079" (2.00mm) pitch for both row and position spacing
• Mounting & Termination: Through-hole solder termination for PCB assembly
• Electrical Ratings: 2A current rating and 250V voltage rating
• Operating Temperature Range: -30°C to 85°C

The DF11-26DP-2DSA(08) meets all these criteria and is the manufacturer-recommended substitute. Both parts share identical mechanical and electrical specifications within the DF11 series, ensuring direct functional equivalence for circuit board integration.

Parameter Comparison

Engineering Selection Recommendations

The DF11-26DP-2DSA(08) is the direct functional equivalent for the obsolete DF11-26DP-2DSA(73). Selection of this substitute is supported by:

• Product Status: The substitute is in active production, ensuring long-term availability and supply chain stability
• Compliance Certifications: The DF11-26DP-2DSA(08) is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards
• Moisture Sensitivity: MSL rating of 1 (Unlimited) provides superior handling flexibility compared to the original part
• Electrical & Mechanical Equivalence: All critical parameters—position count, pitch, current/voltage ratings, and operating temperature—are identical
• Inventory Availability: 9582 units in stock provide immediate procurement capability

For applications requiring the DF11-26DP-2DSA(73), direct substitution with DF11-26DP-2DSA(08) is appropriate without circuit redesign or mechanical modification.

Frequently Asked Questions (FAQ)

Q: What is the difference between DF11-26DP-2DSA(73) and DF11-26DP-2DSA(08)?

A: Both connectors are identical in mechanical and electrical specifications. The suffix designations (73) and (08) represent different manufacturing batches or packaging configurations. The (08) variant is the current active production version.

Q: Can DF11-26DP-2DSA(08) be used as a direct replacement in existing designs?

A: Yes. The substitute part maintains 100% compatibility with designs originally specified for DF11-26DP-2DSA(73). No PCB layout modifications, schematic changes, or mechanical adjustments are required.

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

A: Substitution is determined by matching: connector series (DF11), position count (26), row configuration (2), mating pitch (2.00mm), connector type (header), mounting method (through-hole), termination type (solder), and electrical ratings (2A/250V).

Q: Is the substitute part RoHS compliant?

A: Yes. DF11-26DP-2DSA(08) is ROHS3 compliant, meeting current environmental regulations for lead-free and restricted substance requirements.

Q: What is the moisture sensitivity level of the substitute?

A: The DF11-26DP-2DSA(08) has an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there any packaging differences between the original and substitute parts?

A: The original part packaging is not specified. The substitute is supplied in bulk packaging, which is standard for through-hole connector components.
