DF1EC-6P-2.5DSA(01) Equivalent & Substitute Parts

Part Overview

The DF1EC-6P-2.5DSA(01) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole mounting in board-to-cable/wire applications. This connector features 6 positions with 0.098" (2.50mm) pitch spacing, shrouded 4-wall construction, and solder termination. The part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the DF1EC-6P-2.5DSA(01) is determined by the following critical parameters: connector type (header), contact type (male pin), mounting method (through hole), termination type (solder), shrouding configuration (4-wall), and pitch spacing (0.098" / 2.50mm). Parts meeting these specifications are classified as direct equivalents. The DF1EC-6P-2.5DSA(36) represents a direct equivalent within the same DF1E series, differing only in product status (active vs. obsolete) and packaging configuration. The TE Connectivity 1888291-6 is listed as a manufacturer-recommended alternative but operates at a different pitch (0.100" / 2.54mm) and position count (8 positions), requiring design-level evaluation for compatibility.

Parameter Comparison

Engineering Selection Recommendations

The DF1EC-6P-2.5DSA(36) is the primary equivalent for the obsolete DF1EC-6P-2.5DSA(01). Both parts share identical electrical and mechanical specifications within the DF1E series, with the primary distinction being product status. The DF1EC-6P-2.5DSA(36) is currently in active production with ROHS3 compliance and REACH unaffected status, making it suitable for direct substitution in new designs and ongoing production support.

The TE Connectivity 1888291-6 is listed as a manufacturer-recommended alternative but introduces design modifications. This part operates at 0.100" (2.54mm) pitch versus the original 0.098" (2.50mm) specification and accommodates 8 positions instead of 6. Additionally, the 1888291-6 features tin contact finish and phosphor bronze contact material, differing from the gold-plated brass contacts of the original part. This alternative requires PCB layout redesign and connector cavity reconfiguration and is not a pin-compatible substitute.

Frequently Asked Questions (FAQ)

Q: Can the DF1EC-6P-2.5DSA(36) be used as a direct replacement for the DF1EC-6P-2.5DSA(01)?

A: Yes. Both parts are identical in electrical and mechanical specifications. The DF1EC-6P-2.5DSA(36) differs only in product status (active vs. obsolete) and packaging (bulk vs. standard). No design modifications are required.

Q: What are the key differences between the Hirose DF1E series substitute and the TE Connectivity 1888291-6?

A: The TE Connectivity 1888291-6 operates at 0.100" (2.54mm) pitch spacing with 8 positions, compared to the 0.098" (2.50mm) pitch and 6-position configuration of the DF1E series. Contact finish and material composition also differ. This part requires design-level evaluation and is not pin-compatible.

Q: Is the DF1EC-6P-2.5DSA(36) RoHS compliant?

A: Yes. The DF1EC-6P-2.5DSA(36) is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity level for these connectors?

A: All listed parts carry Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without special moisture control requirements.

Q: Can the 1888291-6 be used in applications requiring 0.098" (2.50mm) pitch spacing?

A: No. The 1888291-6 operates at 0.100" (2.54mm) pitch spacing. Using this part in a design specified for 0.098" (2.50mm) pitch will result in mechanical misalignment and connector failure.
