Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF11-12DP-2DS(79) is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Manufacturer: Hirose Electric Co Ltd
• Series: DF11
• Number of Positions: 12
• Number of Rows: 2
• Pitch - Mating: 0.079" (2.00mm)
• Connector Type: Header
• Contact Type: Male Pin
• Voltage Rating: 250V
• Current Rating: 2A
• Operating Temperature Range: -40°C ~ 85°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Compliance: ROHS3 Compliant
• ECCN Classification: EAR99
• HTSUS Code: 8536.69.4040

The substitute part DF11-12DP-2DS(52) maintains all critical electrical parameters and series designation. The primary difference is the mounting configuration: the substitute features right-angle through-hole mounting with shrouded 4-wall design and detent lock fastening, compared to the original part's standard through-hole configuration. Both parts are manufactured by Hirose Electric Co Ltd within the DF11 series and satisfy identical electrical specifications.

Engineering Selection Recommendations

DF11-12DP-2DS(52) as Primary Substitute:

The DF11-12DP-2DS(52) is the designated substitute for the obsolete DF11-12DP-2DS(79). This substitution is supported by:

1. Product Status Alignment: The substitute part maintains active product status with Hirose Electric Co Ltd, ensuring ongoing availability and manufacturing support.

2. Electrical Compliance: Both parts satisfy identical electrical specifications including 250V voltage rating, 2A current rating, and -40°C to 85°C operating temperature range.

3. Regulatory Compliance: The substitute maintains ROHS3 compliance, EAR99 ECCN classification, and identical HTSUS coding (8536.69.4040), ensuring regulatory equivalence.

4. Series Continuity: Both connectors belong to the DF11 series with matching 12-position, 2-row configuration and 2.00mm pitch specifications.

5. Moisture Sensitivity: MSL rating of 1 (Unlimited) is maintained, indicating no moisture sensitivity constraints for either part.

Design Consideration: The substitute features right-angle mounting orientation with 4-wall shrouding and detent lock fastening. PCB layout and mechanical clearance verification is required to confirm compatibility with the original application's spatial constraints and mounting requirements.

Frequently Asked Questions (FAQ)

Q: Can DF11-12DP-2DS(52) directly replace DF11-12DP-2DS(79) in all applications?

A: Both parts share identical electrical specifications (250V, 2A, -40°C to 85°C operating range) and series designation (DF11, 12 positions, 2 rows, 2.00mm pitch). The primary difference is mounting configuration: the substitute uses right-angle through-hole mounting with 4-wall shrouding, while the original uses standard through-hole mounting. Mechanical compatibility depends on PCB layout and available space for the right-angle orientation.

Q: What is the significance of the part number suffix (79) versus (52)?

A: The suffix designates specific mechanical and packaging variants within the DF11 series. The (79) variant is obsolete, while the (52) variant is currently in active production. Both maintain identical electrical and environmental specifications.

Q: Are there compliance or certification differences between these parts?

A: No. Both parts carry ROHS3 compliance, EAR99 ECCN classification, and identical HTSUS coding. Moisture sensitivity levels are equivalent at MSL 1 (Unlimited).

Q: What packaging is available for the substitute part?

A: The DF11-12DP-2DS(52) is supplied in tube packaging with 12,347 pieces currently in stock.

Q: Does the right-angle mounting of the substitute affect electrical performance?

A: No. The right-angle mounting is a mechanical configuration change only. Electrical specifications including voltage rating, current rating, contact material (brass with gold finish), and operating temperature range remain identical.

Q: What is the contact configuration for both parts?

A: Both parts feature male pin contacts with 0.079" (2.00mm) pitch. The substitute specifies brass material with gold mating surface finish and 0.118" (3.00mm) contact length for both mating and post sections.

Q: Are there any environmental or temperature limitations?

A: Both parts operate across -40°C to 85°C with MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints. The substitute carries UL94 V-0 material flammability rating.
