Substitute Part Grouping Explanation

The DF1B-4S-2.5R qualifies as a direct substitute based on the following critical parameters:

• Connector Type & Contact Configuration: Both parts feature 4-position female socket contacts with identical 0.098" (2.50mm) pitch spacing
• Mounting & Mechanical Compatibility: Both are free-hanging, in-line connectors with single-row configuration
• Termination Compatibility: The DF1B-4S-2.5R supports both crimp and IDC termination methods, encompassing the IDC requirement of the main part
• Electrical & Environmental Compliance: Both maintain ROHS3 compliance, unlimited MSL rating, and REACH unaffected status
• Manufacturer Consistency: Both are Hirose Electric products within the DF series family

The DF1B-4S-2.5R represents an evolution within the Hirose DF connector family, offering expanded termination options while maintaining mechanical and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The DF1B-4S-2.5R is the appropriate substitute for the DF1-4S-2.5R24(05) based on the following factors:

• Supply Continuity: The DF1B-4S-2.5R maintains active production status with 4699 units in stock, whereas the main part is Last Time Buy with limited availability
• Regulatory Compliance: Both parts maintain identical ROHS3 compliance and REACH unaffected status, ensuring regulatory requirements are met
• Functional Compatibility: Identical pitch, position count, and mounting configuration ensure mechanical interchangeability
• Termination Flexibility: The DF1B-4S-2.5R supports IDC termination as required, with additional crimp capability for design flexibility
• Environmental Rating: Both parts carry MSL 1 (Unlimited) rating, suitable for standard storage and handling conditions

Frequently Asked Questions (FAQ)

Q: Can the DF1B-4S-2.5R directly replace the DF1-4S-2.5R24(05) in existing designs?

A: Yes. Both connectors share identical pitch (0.098" / 2.50mm), position count (4), and mounting configuration (free-hanging, in-line). The DF1B-4S-2.5R supports IDC termination, matching the primary termination method of the original part.

Q: What is the difference between Socket and Receptacle connector types in this comparison?

A: In Hirose terminology, both designations refer to female contact housings compatible with male pin connectors. The functional role and mating interface remain equivalent.

Q: Are there any environmental or compliance differences between these parts?

A: No. Both parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) rating. Environmental operating conditions and moisture sensitivity are equivalent.

Q: Why does the DF1B-4S-2.5R support both crimp and IDC termination?

A: The DF1B series represents a later generation within the Hirose DF family, offering expanded termination options. IDC termination capability is retained for backward compatibility with existing wire preparation methods.

Q: Is the DF1B-4S-2.5R available in the same packaging as the original part?

A: Both parts are supplied in bulk packaging. Verify specific packaging requirements with your procurement department for order quantities and delivery specifications.
