Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LEHR-02V-S-A(HF) is determined by strict equivalence across the following critical parameters:

• Connector Type & Function: Receptacle housing for socket contact, board-to-cable/wire configuration
• Electrical Specifications: 2-position, 1.80mm pitch, 300V voltage rating, 3A current rating (22 AWG)
• Termination Method: Crimp termination
• Mounting Configuration: Free hanging (in-line)
• Environmental Ratings: Operating temperature range -55°C ~ 105°C, MSL 1

The substitute part LEAR-02V-S meets all critical functional and electrical parameters. While the housing material differs (PBT vs. PA66 glass-filled nylon), both materials satisfy the specified electrical and thermal requirements for this connector category. The substitute maintains identical pitch, position count, voltage/current ratings, and termination method.

Parameter Comparison

Engineering Selection Recommendations

The LEAR-02V-S is the direct functional equivalent for the obsolete LEHR-02V-S-A(HF). Selection of this substitute is supported by:

• Electrical Equivalence: Identical voltage (300V), current (3A at 22 AWG), and pitch (1.80mm) specifications
• Mechanical Compatibility: Same connector type, position count, termination method, and mounting configuration
• Environmental Performance: Matching operating temperature range (-55°C ~ 105°C) and MSL rating (1)
• Active Product Status: LEAR-02V-S is currently in active production with documented inventory availability (123,398 pcs)
• Regulatory Compliance: LEAR-02V-S carries ROHS3 compliance certification and REACH unaffected status, providing documented regulatory standing

The material difference (PBT vs. PA66 glass-filled nylon) does not impact functional compatibility within the specified electrical and thermal operating envelope.

Frequently Asked Questions (FAQ)

Q: Can LEAR-02V-S directly replace LEHR-02V-S-A(HF) in existing assemblies?

A: Yes. Both parts are 2-position receptacle housings with identical 1.80mm pitch, crimp termination, and electrical ratings (300V, 3A). The connector interface and mating characteristics are equivalent.

Q: What is the significance of the different housing materials?

A: LEHR-02V-S-A(HF) uses PA66 glass-filled nylon; LEAR-02V-S uses PBT. Both materials meet the specified operating temperature range (-55°C ~ 105°C) and voltage rating (300V). Material selection does not affect electrical or thermal performance within these parameters.

Q: Why is LEHR-02V-S-A(HF) classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured. LEAR-02V-S is the active equivalent available for new procurement and ongoing system support.

Q: Are there packaging differences between these parts?

A: LEHR-02V-S-A(HF) packaging is not specified in available data. LEAR-02V-S is supplied in bulk packaging. Confirm packaging requirements with your procurement specification.

Q: What compliance certifications apply to the substitute?

A: LEAR-02V-S carries ROHS3 compliance and is REACH unaffected. Verify compliance requirements against your system specifications.

Q: Is the pitch measurement identical between both parts?

A: Yes. Both parts specify 0.071" (1.80mm) pitch, ensuring mechanical and electrical compatibility in mating applications.
