DF1E-5P-2.5DS Equivalent & Substitute Parts

Part Overview

The Hirose Electric DF1E-5P-2.5DS is a shrouded right-angle rectangular connector header with 5 positions at 2.5mm pitch, designed for through-hole board-to-cable/wire applications. This connector features male pins with tin-plated brass contacts, polyamide insulation, and a 3A current rating across an operating temperature range of -35°C to 85°C. The part is classified as obsolete, necessitating identification of functionally equivalent alternatives from active manufacturers for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution of the DF1E-5P-2.5DS is constrained by the following critical parameters:

Pitch Incompatibility: The main part operates at 2.5mm (0.098") pitch. All identified substitute parts from Molex and TE Connectivity operate at 2.54mm (0.100") pitch. This represents a 0.04mm difference per position, resulting in cumulative spacing variations that prevent direct mechanical interchangeability without PCB redesign.

Allowed Substitution Criteria (based on provided parameters):

Connector type: Header
Contact type: Male Pin
Number of positions: 5
Mounting: Through Hole, Right Angle
Shrouding: Shrouded - 4 Wall
Termination: Solder
Fastening: Latch Holder
Flammability: UL94 V-0

0705530004 (Gold mating finish, 15.0µin)
0705530039 (Tin mating finish, 150.0µin)
0705530109 (Gold mating finish, 30.0µin)

Group 2 - TE Connectivity AMPMODU MTE Series (2.54mm pitch)

103634-4 (Tin-Lead finish, standard keying)

All substitutes share the same 5-position, shrouded 4-wall configuration with through-hole right-angle mounting and solder termination. Contact material differs (Phosphor Bronze or Brass vs. original Brass), and operating temperature ranges extend to -40°C or -65°C minimum and 105°C maximum, exceeding the original specification.

Frequently Asked Questions (FAQ)

Q: Can the DF1E-5P-2.5DS be directly replaced with a 2.54mm pitch substitute without PCB modification?

A: No. The 0.04mm pitch difference per position creates cumulative spacing variations that prevent mechanical interchangeability. PCB redesign is required to accommodate the 2.54mm pitch grid.

Q: What is the primary difference between Molex and TE Connectivity substitutes?

A: Molex SL 70553 series uses Phosphor Bronze contacts with polyester glass-filled insulation and is ROHS3 compliant. TE Connectivity AMPMODU MTE series uses brass contacts with thermoplastic insulation and offers extended temperature range (-65°C minimum). Contact material and insulation composition differ, though both meet UL94 V-0 flammability requirements.

Q: Which substitute offers the best compliance profile?

A: Molex 0705530004, 0705530039, and 0705530109 are ROHS3 compliant with active product status. TE Connectivity variants have mixed RoHS applicability. For new designs requiring RoHS compliance, Molex options are preferred.

Q: Does contact finish affect electrical performance?

A: Gold-plated contacts (0705530004, 0705530109, 103635-4, 103673-4, 103904-4, 103906-4) provide superior corrosion resistance and lower contact resistance over extended service life. Tin-plated contacts (0705530039, 103634-4, 2-103634-7) are suitable for controlled environments with lower corrosion risk.

Q: Are there inventory differences between substitute options?

A: Yes. Molex 0705530004 has the highest inventory (13,964 units), followed by 0705530039 (13,517 units). TE Connectivity 103906-4 has 6,532 units. TE Connectivity 103904-4 has the lowest availability (658 units). Molex options provide superior supply chain stability.

Q: What is the significance of the Board Lock feature in TE Connectivity parts?

A: Board Lock (present in 103672-4, 103673-4, 103904-4) provides mechanical retention during mating, preventing accidental disconnection. Standard keying (103634-4, 103635-4, 103906-4) relies on latch holder engagement alone. Selection depends on application vibration and shock requirements.

Q: Can substitutes be mixed within a single design?

A: No. Mixing Molex and TE Connectivity parts creates inconsistent contact materials, insulation types, and mechanical features. Standardize on a single manufacturer series within a design to ensure uniform electrical and mechanical performance.
