EM35MP-4PC Equivalent & Substitute Parts

Part Overview

The EM35MP-4PC is a 4-position rectangular connector housing plug manufactured by Hirose Electric Co., Ltd., part of the EnerBee™ EM series. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The connector features a male pin contact type with crimp termination and latch lock fastening, designed for free hanging in-line mounting applications. Due to its obsolete status, equivalent parts with active product status are required to ensure supply chain continuity and long-term component availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EM35MP-4PC is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Plug with male pin contacts
• Position Count: 4 positions
• Mounting Architecture: Free hanging in-line configuration
• Termination Method: Crimp contact termination
• Fastening Mechanism: Latch lock fastening
• Material Specification: Polybutylene Terephthalate (PBT) insulation
• Thermal Operating Range: -40°C to 125°C
• Regulatory Compliance: RoHS compliant

The substitute part EM35MP-4PC(81) maintains compatibility with the original EM35MP-4PC across all critical electrical and mechanical parameters. The primary distinction is the transition from obsolete to active product status, enabling continued procurement and supply chain support. The packaging format change from standard to bag does not affect functional compatibility or electrical performance.

Parameter Comparison

Engineering Selection Recommendations

The EM35MP-4PC(81) is the direct substitute for the obsolete EM35MP-4PC. Both components share identical electrical and mechanical specifications, including connector architecture, contact configuration, termination method, and thermal operating range. The transition from obsolete to active product status makes EM35MP-4PC(81) the appropriate selection for new designs and replacement applications.

Both parts maintain RoHS compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols. The packaging format difference does not impact functional performance or electrical characteristics. Selection of the active substitute part ensures long-term supply chain availability and eliminates obsolescence risk.

Frequently Asked Questions (FAQ)

Q: Can EM35MP-4PC(81) be used as a direct replacement for EM35MP-4PC?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: 4-position plug configuration, male pin contacts, crimp termination, latch lock fastening, PBT insulation, and -40°C to 125°C operating range. The primary difference is product status; EM35MP-4PC(81) is active while EM35MP-4PC is obsolete.

Q: What is the significance of the "(81)" designation in EM35MP-4PC(81)?

A: The "(81)" suffix indicates a packaging or variant specification within the EnerBee™ EM series. This designation does not affect electrical performance or mechanical compatibility with the original part number.

Q: Are there any compliance or certification differences between these parts?

A: No. Both EM35MP-4PC and EM35MP-4PC(81) are RoHS compliant with MSL 1 rating. Regulatory compliance and environmental certifications are identical.

Q: Does the packaging change from standard to bag affect connector performance?

A: No. Packaging format is a logistics and storage consideration only. The connector's electrical and mechanical characteristics remain unchanged regardless of packaging type.

Q: Why is the original EM35MP-4PC classified as obsolete?

A: Obsolescence typically reflects manufacturer discontinuation decisions. The active substitute EM35MP-4PC(81) provides equivalent functionality with ongoing supply chain support.
