EHR-7 Equivalent & Substitute Parts Reference

Part Overview

The EHR-7 is a 7-position rectangular connector housing manufactured by JST Sales America Inc. in the EH series. This receptacle housing accepts female socket contacts with a 2.50mm pitch and is designed for free-hanging in-line applications using crimp termination. The part is actively produced and ROHS3 compliant, making it suitable for modern electronic assemblies requiring standard rectangular interconnection solutions.

Substitute parts become necessary when primary sourcing is unavailable, when alternative manufacturers offer improved lead times or inventory availability, or when design flexibility permits equivalent connector housings from qualified manufacturers.

Substitute Part Grouping Explanation

Substitution eligibility for the EHR-7 is determined by strict equivalence across the following critical parameters:

Connector Type & Contact Configuration: Must be receptacle housing with female socket contacts
Position Count & Pitch: Must maintain 7 positions at 0.098" (2.50mm) pitch
Row Configuration: Single row layout only
Mounting & Termination: Free hanging in-line mounting with crimp termination required
Material & Temperature: Polyamide (PA66) insulation with operating range of -25°C minimum
Compliance: ROHS3 compliance mandatory; MSL 1 rating required

The three parts listed below meet these criteria as direct substitutes for the EHR-7 rectangular connector housing.

Engineering Selection Recommendations

All three parts listed are active products with ROHS3 compliance and MSL 1 ratings, qualifying them as equivalent substitutes for the EHR-7.

EHR-7 (JST Sales America Inc.): Primary part with established supply chain. Suitable for standard applications within the -25°C to 85°C operating range.

440133-7 (TE Connectivity AMP Connectors): Extended operating temperature range to 105°C provides additional thermal margin. Highest current inventory (7927 pcs) supports rapid procurement. Suitable for applications requiring enhanced temperature performance or when JST sourcing is constrained.

25CH-C-07 (Adam Tech): Includes friction lock fastening feature and white housing color. Inventory of 4117 pcs available. Suitable for applications where mechanical retention enhancement or color differentiation is beneficial. Note housing color differs from EHR-7 natural finish.

Frequently Asked Questions (FAQ)

Q: Can the 440133-7 be used in place of the EHR-7 in all applications?

A: The 440133-7 meets all critical electrical and mechanical parameters for direct substitution. The extended operating temperature range (-25°C to 105°C versus -25°C to 85°C) provides additional capability without reducing performance in standard temperature applications.

Q: What is the significance of the friction lock feature on the 25CH-C-07?

A: The friction lock fastening type on the 25CH-C-07 provides mechanical retention between mating connectors. The EHR-7 and 440133-7 lack this feature. Selection depends on application requirements for connector retention force.

Q: Does the white color of the 25CH-C-07 affect electrical performance?

A: Housing color is a cosmetic and identification parameter only. The white color of the 25CH-C-07 does not affect electrical or mechanical performance. Selection should be based on assembly or identification requirements.

Q: Are contacts included with these connector housings?

A: No. All three parts (EHR-7, 440133-7, and 25CH-C-07) are housings only. Female socket contacts must be sourced separately and crimped into the housing.

Q: What is the pitch specification and why is it critical?

A: Pitch is the center-to-center distance between adjacent contact positions, specified as 0.098" (2.50mm) for all three parts. Pitch must match exactly between housing and mating connector to ensure proper alignment and electrical contact.

Q: Can these housings be used interchangeably in existing assemblies?

A: Mechanical and electrical interchangeability is confirmed across all three parts for the specified 7-position, 2.50mm pitch configuration. Physical dimensions and contact spacing are equivalent. Verify mating connector compatibility before assembly.
