Engineering Selection Recommendations

Primary Active Substitutes (Recommended for New Designs)

The following parts are suitable for direct functional replacement with RJE031880310 based on Active product status and compliance certifications:

0855035001 (Molex): Active, ROHS3 Compliant. Preferred for Cat5e-rated applications requiring extended temperature range (-40°C to 85°C). Thermally equivalent to the main part.
1-1705951-1 / 1705951-1 (TE Connectivity AMP): Active, RoHS Compliant. Suitable for Cat3 applications with matching board lock and phosphor bronze contacts. Available in both Tray and Cut Tape packaging.
54602-908LF (Amphenol ICC FCI): Active, RoHS Compliant. Copper alloy contacts with Cat3 rating. Operates to -40°C to 70°C; verify thermal requirements for applications exceeding 70°C.
A-20042/LP (Assmann WSW): Active, ROHS3 Compliant. Unrated configuration matching the main part's electrical profile. Operating range -40°C to 85°C.

Conditional Substitutes

92250-088LF (Amphenol ICC FCI): Shielded configuration. Select only when EMI shielding is required. Operates -40°C to 70°C; not suitable for applications requiring extended temperature to 85°C. Active, RoHS Compliant.

Obsolete / Not Recommended for New Designs

E5388-000012-L (Pulse Electronics): Marked Obsolete status. Use only for legacy system maintenance or repair where form-factor matching is critical.

Frequently Asked Questions (FAQ)

Q: Can I substitute RJE031880310 with the shielded version 92250-088LF?

A: The shielded version 92250-088LF provides electrical isolation from external EMI. Mechanical fit and functional operation are equivalent; however, it operates to -40°C to 70°C versus the main part's -40°C to 85°C range. Use shielded substitution only when EMI mitigation is required for the application.

Q: What is the difference between Cat3 and Cat5e ratings?

A: Cat5e (0855035001) supports higher bandwidth specifications suitable for Ethernet applications. Cat3 (54602-908LF, 1-1705951-1, 1705951-1, E5388-000012-L) provides lower bandwidth capacity but maintains mechanical and electrical interchangeability with unrated connectors such as RJE031880310. Select Cat3 or Cat5e based on application data rate requirements.

Q: Does packaging format (Tray vs. Cut Tape vs. Bulk) affect connector performance?

A: Packaging format does not affect connector electrical or mechanical performance. Selection depends on manufacturing requirements: Tray format for robotic placement, Cut Tape for sequential feeding, and Bulk for high-volume manual assembly. Choose based on production equipment compatibility and assembly methodology.

Q: Are TE Connectivity 1-1705951-1 and 1705951-1 functionally identical?

A: Both parts share identical specifications (8P8C, 90° right-angle, Cat3, phosphor bronze contacts, PBT housing, -40°C to 85°C). The difference is packaging: 1-1705951-1 is supplied in Tray format, while 1705951-1 is supplied in Cut Tape format. Select based on assembly equipment requirements.

Q: Can I use substitutes with different contact finish thicknesses?

A: Contact finish thickness variation (5.00µin to 30.0µin) does not impact connector interoperability or electrical performance within the specified operating parameters. All finishes provide equivalent gold plating for corrosion resistance and contact reliability.

Q: Is Molex 0855035001 a suitable upgrade from RJE031880310?

A: Yes. The 0855035001 provides Cat5e rating, higher bandwidth capacity, and equivalent mechanical compatibility with active product status and ROHS3 compliance. Temperature range matches the main part (-40°C to 85°C). Use for applications where Cat5e performance is beneficial or required.

Q: Why is E5388-000012-L marked Obsolete?

A: Obsolete status indicates discontinued production by the manufacturer. While functional equivalence exists, active alternatives (0855035001, 54602-908LF, 1-1705951-1, 1705951-1, A-20042/LP) are recommended for new designs to ensure long-term supply chain stability.
