DF1EA-2EP-2.5C Equivalent & Substitute Parts

Part Overview

The DF1EA-2EP-2.5C is a 2-position rectangular connector plug housing manufactured by Hirose Electric Co Ltd. This connector features a 2.50mm pitch, crimp contact termination, and latch holder fastening. The part is actively produced and ROHS3 compliant, with an operating temperature range of -35°C to 85°C. Substitute parts are necessary when specific color variants are required, when alternative manufacturer sourcing is preferred for supply chain optimization, or when extended temperature performance is needed within compatible parameter ranges.

Substitute Part Grouping Explanation

Substitution eligibility for the DF1EA-2EP-2.5C is determined by the following critical parameters: connector type (plug), contact type (male pin), number of positions (2), pitch (2.50mm), number of rows (1), mounting type (free hanging in-line), contact termination (crimp), and fastening type (latch holder). All identified substitute parts maintain these core electrical and mechanical specifications.

The substitute parts are grouped into two manufacturer families:

TE Connectivity AMP Connectors (Grace Inertia, GIC Series): Parts 1-1903388-2, 1903388-1, 2-1903388-3, and 3-1903388-4 are parametric equivalents that differ only in housing color (red, natural, blue, and yellow respectively). These parts feature polybutylene terephthalate (PBT) glass-filled insulation and an extended operating temperature range of -30°C to 105°C.

Molex (CP-2.5 500593 Series): Part 5005930200 is a parametric equivalent with natural housing color, polybutylene terephthalate (PBT) insulation, and an operating temperature range of -40°C to 85°C.

All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with the original part's environmental and regulatory requirements.

Engineering Selection Recommendations

All substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the original DF1EA-2EP-2.5C specification. Selection among available substitutes should be based on application-specific requirements:

For applications requiring extended upper temperature performance beyond 85°C, the TE Connectivity AMP Connectors (1-1903388-2, 1903388-1, 2-1903388-3, 3-1903388-4) offer an operating range to 105°C. These parts are suitable for thermal environments where the original Hirose part's maximum rating is insufficient.

For applications requiring extended lower temperature performance to -40°C, the Molex 5005930200 provides this capability while maintaining the 85°C upper limit of the original part.

Housing color selection among TE Connectivity variants (red, natural, blue, yellow) or Molex natural color should be determined by circuit identification or assembly requirements. All variants maintain identical electrical and mechanical interface specifications.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity AMP Connectors substitute for the Hirose DF1EA-2EP-2.5C in all applications?

A: Yes, provided the application does not require the specific white housing color of the original part. The TE Connectivity variants (1-1903388-2, 1903388-1, 2-1903388-3, 3-1903388-4) maintain all critical electrical and mechanical parameters. Housing color differences do not affect electrical performance or mechanical compatibility.

Q: What is the difference between the TE Connectivity and Molex substitute options?

A: The primary difference is operating temperature range. TE Connectivity parts operate from -30°C to 105°C, while the Molex part operates from -40°C to 85°C. Both maintain the same 2-position, 2.50mm pitch configuration and crimp termination. Insulation material differs slightly (TE uses glass-filled PBT; Molex uses standard PBT), but both are ROHS3 compliant.

Q: Are contacts included with these connector housings?

A: No. All parts listed—the original DF1EA-2EP-2.5C and all substitutes—are housings only. Contacts must be sourced separately and are not included in the package.

Q: Do all substitute parts have the same moisture sensitivity level as the original?

A: Yes. All parts maintain MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Which substitute part offers the widest operating temperature range?

A: The TE Connectivity AMP Connectors (1-1903388-2, 1903388-1, 2-1903388-3, 3-1903388-4) offer the widest range at -30°C to 105°C, extending the upper limit by 20°C compared to the original Hirose part.
