Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DF1-9P-2.5DS(05) are identified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Connector type (Header, male pin contact)
• Mounting configuration (Through hole, right angle)
• Termination method (Solder)
• Shrouding design (Shrouded - 1 wall)
• Contact material and finish (Brass with tin plating)
• Insulation material (Polyamide/Nylon)
• Flammability rating (UL94 V-0)
• Environmental compliance (RoHS, MSL 1)

Identified Substitutes:

• Molex 0022058104 (KK254 Series)
• Molex 0022058109 (KK254 Series)

Both Molex substitutes are 10-position headers with 2.54mm pitch, loaded with 9 positions. This configuration accommodates the 9-position requirement of the original part while providing a standard pitch alternative. Both parts maintain equivalent electrical performance, material specifications, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The DF1-9P-2.5DS(05) is designated Last Time Buy, indicating end-of-life status. The Molex KK254 series substitutes (0022058104 and 0022058109) are both Active products with confirmed ongoing availability.

Compliance & Certification: Both substitute parts maintain UL94 V-0 flammability certification and MSL 1 moisture sensitivity rating, matching the original specification. The Molex parts carry ROHS3 compliance, exceeding the RoHS Compliant status of the original part.

Electrical & Mechanical Equivalence: The substitutes provide equivalent electrical performance through identical contact material (brass with tin finish), shrouding design, and termination method. The 2.54mm pitch represents a standard industry alternative to the 2.5mm pitch, with both parts accommodating 9-position loading within a 10-position housing.

Inventory & Supply: Both Molex substitutes maintain active production status with confirmed stock availability (795 and 1037 units respectively), ensuring long-term supply continuity compared to the discontinued Hirose part.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0022058104 and 0022058109 directly replace the DF1-9P-2.5DS(05)?

A: Both Molex parts are functionally equivalent substitutes. They share identical connector type, contact configuration, mounting method, and material specifications. The primary difference is pitch: 2.54mm (Molex) versus 2.50mm (Hirose). Both parts are loaded with 9 positions within a 10-position housing, accommodating the original 9-position requirement.

Q: What is the difference between the two Molex substitute parts?

A: The Molex 0022058104 and 0022058109 are both KK254 series headers with identical electrical and mechanical specifications. Both are 10-position, 2.54mm pitch, right-angle, through-hole connectors with 9 positions loaded. The parts differ only in inventory availability and manufacturing lot designation.

Q: Does the pitch difference (2.50mm vs 2.54mm) affect compatibility?

A: The pitch difference requires PCB redesign if the original layout was designed specifically for 2.50mm spacing. However, both pitches are standard in rectangular connector applications. The 2.54mm pitch is more widely available in active production, supporting long-term supply chain stability.

Q: Are the Molex substitutes RoHS compliant?

A: Yes. Both Molex parts carry ROHS3 compliance, which exceeds the RoHS Compliant designation of the original Hirose part. This ensures regulatory compliance for current and future applications.

Q: What is the significance of the 10-position housing with 9 positions loaded?

A: The 10-position housing accommodates the 9-position requirement of the original part while utilizing a standard Molex KK254 platform. The unused 10th position remains empty, maintaining full functional compatibility with the original 9-position design.
