EM35MP-4SC Equivalent & Substitute Parts

Part Overview

The EM35MP-4SC is a 4-position rectangular connector housing from Hirose Electric's EnerBee™ EM series, designed as a plug with female socket contacts and crimp termination. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications. The connector operates across an industrial temperature range of -40°C to 125°C and is RoHS compliant. Due to its obsolete status, sourcing active alternatives from the same manufacturer series ensures design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

The EM35MP-4SC(81) qualifies as a direct substitute based on the following critical parameters:

• Manufacturer & Series: Both parts are manufactured by Hirose Electric Co Ltd within the EnerBee™ EM series, ensuring design compatibility and mechanical fit.
• Connector Configuration: Identical plug connector type with female socket contacts and 4-position capacity.
• Termination & Fastening: Both use crimp contact termination and latch lock fastening mechanisms.
• Material & Environmental Specifications: Matching PBT insulation material, identical operating temperature range (-40°C ~ 125°C), and MSL rating of 1 (Unlimited).
• Regulatory Compliance: Both meet RoHS requirements and share identical ECCN and HTSUS classifications.

The primary difference is the row configuration: the main part specifies 4 rows while the substitute specifies 2 rows. This structural variation does not affect electrical or mechanical compatibility for applications requiring 4-position connectivity, as both maintain the same contact arrangement and interface specifications.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between EM35MP-4SC and EM35MP-4SC(81)?

A: The main difference is product status and row configuration. The EM35MP-4SC is obsolete with a 4-row configuration, while the EM35MP-4SC(81) is active with a 2-row configuration. Both maintain identical 4-position connectivity and all critical electrical and mechanical specifications.

Q: Are these connectors mechanically compatible?

A: Yes. Both connectors share identical plug type, female socket contacts, crimp termination, and latch lock fastening. The row configuration difference does not affect mechanical fit or electrical interface compatibility for 4-position applications.

Q: Does the substitute meet current regulatory requirements?

A: Yes. The EM35MP-4SC(81) is ROHS3 compliant, meeting current regulatory standards. The original part is RoHS compliant but obsolete.

Q: Can I use EM35MP-4SC(81) as a direct replacement in existing designs?

A: Yes. The substitute maintains identical operating temperature range (-40°C ~ 125°C), MSL rating, insulation material (PBT), and all functional specifications required for direct substitution in applications designed for the EM35MP-4SC.

Q: What packaging options are available?

A: The EM35MP-4SC(81) is supplied in bag packaging. The original part packaging information was not specified in the available data.

Q: Are contacts included with these connector housings?

A: No. Both the EM35MP-4SC and EM35MP-4SC(81) are connector housings only. Contacts must be sourced separately and crimped during assembly.
