Substitute Part Grouping Explanation
Substitution eligibility for the E.FL-LP-040(01) is determined by strict equivalence across the following critical parameters:
- Connector Style: E.FL series only
- Connector Type: Plug, Female Socket configuration
- Impedance: 50 Ohms (RF performance requirement)
- Contact and Shield Termination: Solder (assembly compatibility)
- Mounting Type: Free Hanging (In-Line), Right Angle (mechanical fit)
- Fastening Type: Snap-On (mating interface)
- Frequency Rating: 6 GHz maximum (bandwidth capability)
- Number of Ports: 1 (circuit topology)
- Operating Temperature: -40°C ~ 90°C (environmental specification)
- Mating Cycles: 30 (mechanical durability)
- RoHS Compliance: Required (regulatory requirement)
Parts meeting all these parameters are classified as parametric equivalents and may be substituted without circuit redesign or mechanical rework.

Engineering Selection Recommendations
Both E.FL-LP-040(01) and E.FL-LP-066(01) are active production parts manufactured by Hirose Electric Co Ltd and carry RoHS compliance certification. Selection between these parts may be based on inventory availability: E.FL-LP-040(01) has 701 units in stock, while E.FL-LP-066(01) has 1195 units available. Both parts meet identical electrical specifications (50 Ohm impedance, 6 GHz frequency rating) and mechanical requirements (solder termination, snap-on fastening, 30 mating cycles). No performance degradation occurs when substituting between these parts in applications requiring E.FL connector plugs with female socket configuration.
Frequently Asked Questions (FAQ)
Q: Can E.FL-LP-066(01) be used as a direct replacement for E.FL-LP-040(01)?
A: Yes. Both parts are parametric equivalents meeting identical electrical and mechanical specifications. No circuit redesign or mechanical rework is required for substitution.
Q: What determines if a part is a valid substitute?
A: Substitution requires exact matching across all critical parameters: E.FL connector style, plug female socket type, 50 Ohm impedance, solder termination, free-hanging right-angle mounting, snap-on fastening, 6 GHz frequency rating, single port configuration, -40°C to 90°C operating temperature, 30 mating cycles, and RoHS compliance.
Q: Are there any differences in mechanical fit between these parts?
A: No. Both parts share identical mounting type (free hanging in-line, right angle), fastening mechanism (snap-on), and connector style (E.FL). Mechanical compatibility is guaranteed.
Q: What is the significance of the mating cycle rating?
A: The 30 mating cycle specification indicates the connector is rated for 30 connect-disconnect cycles. Both substitute parts carry this identical rating, ensuring equivalent mechanical durability.
Q: Does RoHS compliance affect substitution eligibility?
A: RoHS compliance is a regulatory requirement for both parts. Both E.FL-LP-040(01) and E.FL-LP-066(01) are RoHS compliant, meeting environmental and regulatory standards for equivalent substitution.
Q: Can these connectors be used interchangeably in production assembly?
A: Yes. Identical solder termination, contact materials (phosphor bronze with gold plating), and dielectric material (liquid crystal polymer) ensure assembly process compatibility and electrical performance equivalence.
